:rofl2:

I was really interested, planned, and budgeted to get one with the above statement. But at 10.5k + hood. Cost wise it makes no sense over other proven kits in the same power range. With a good reliable SC kit out there at 6k and a single turbo at 7.5k I was thinking this would be in the 8k range rather then the ~11k actual price. Not to mention the actual problems inherent with a roots blower, heat soak and actual intake temps, are theoretically "solved" but none are to date proven to be solved.

Lesson is don't buy product that doesn't have any proven data. :icon14:

That goes with RJM transmission as well. When things are quiet seems like something is running into some issues.

Damn.... I cant even take a week to myself...

So let me address some of the items posted above:

Since I had a hand in developing the kit and was a key contributor to the design, sourcing and testing of the product I have made it my best effort to be on here to answer any and all questions. Many of you know me personally and know that I am extremely up front and honest. It has given me a reputation and some people dont like it. Regardless I am here for the community and I am not an employee of RJM. I was not paid for my Design work I did it for the sake of the community and the experience.

So if you have any questions please point them to me. I know every inch of that kit including its capabilities and limitations.


The HOOD Options:
Right now there is only one option and that is to cut your hood. Some like it and some dont... There has been 3 shops that have been contracted to build a hood cowl over the last year... Each shop failing to produce a working prototype. This is especially frustrating to me since I designed the damn thing and its not hard to do. If you have a shop that can do this work let me know. This last shop is stating they will have something for us in March but its literally been pushed back so many times I lost count... If I have to take a week off of work to make one myself I will. If you think your frustrated you have no idea... We know that a Majority of kit buyers are not buying the kit because of the lack of a hood cowl.

Performance:
I hear a few people on here complaining about performance of this kit. None of them have bought the kit, rode in a car with the kit or even asked what the capabilities of the kit are.

RJM set a limit on the stage 1 kits (Pulley Size) for the initial offering because they knew guys would be putting these on stock block cars. RJM does offer any size pulley you want for power levels north of 800whp! the only thing you have to do is make sure you have the supporting mods. That means an upgraded block, Upgraded fuel pump option, Race Heat exchanger, upgraded trans... The RJM kit was designed specifically to let a customer buy the kit and run on the stock block and with little money upgrade it to support north of 800whp+ If you look at the guys who do the stillen kits they are spending $14k+ into their kits and upgrades of that kit to make it hit 700whp+. Now you can buy the whipple kit stage 1: $10.5k + $500 race heat exchanger upgrade and select a 17psi pulley free of charge... so for $11k your getting a more efficient setup with the ability to grow further than what people have already proven with a vortech based system can do for $14k+. Not only that the whipple kit has max TQ at 2600-5200 rpm!!! the Tq curve is damn flat!!! But what does this mean? Well a mid 500's whipple is going to walk that 600whp+ stillen kit every day of the week! Why? Power under the curve!

Now someone mentioned overheating... Why do you think RJM chose the 2.9L? It was chosen for the following reasons:
1. its ability to effortlessly scale power levels
2. its (Twin Screw not roots) efficiency is the highest of every supercharger on the market
3. in this application it is being purposefully under driven
4. its instant response and power delivery

The supercharger is purposefully being under driven to reduce heat soak. I can give you a perfect example. Last year prior to Zdayz debut the kit was onthe Carbon Z as a stage 1.5 (Race heat exchanger and larger injectors). I was there when the car was on the dyno in Florida on a 90*+ day and over 100% humidity and the car did pull after pull after pull for hours with little to no rest. All on a stock block and trans! the car was detuned to mid 500's and mid 400's on tq so the trans would not let go at zdayz. The whole time the car only experienced a 10* rise of iat over ambient temp!!!! That is ******* insane! for a twin screw to be that efficient and that cool on its intake charge temps is excellent! this all measured from a MAP sensor installed into the lower manifold post intercooler. There are a few customer reporting the exact same IAT performance in the real world. Additionally, most cars with this supercharger only see 14-17psi max... with a built block and trans we are able to push north of 28psi!!!!

So will the system overheat? we havent seen it yet...

REAL WORLD Data:
I for one want to see peoples dyno numbers as much as you do however a majority of the people on the group buy live up north and we all know they have taken a beating with the winter this year. Cars are up and running but they havent been on the dyno. As mentioned earlier most customers are on stock blocks and running a combination of 10-12psi pulleys.

Another reason Bobby and RJM havent been on here is because they are building an AWD G37 sedan for a customer with this kit for Drag racing. This is a massive build that has taken every free second of his time! From paint/bodywork to Roll cage fabrication and custom longtube headers. the coordination of this build has been a massive undertaking. not to mention bobby flew out and installed a majority of people's kits for FREE!

So while you guys may be antsy and have the perception that RJM ghosted people its far from the truth! Just ask any of the RJM customers who are running the kit. They get daily and weekly support even on nights and weekends!

Rest assured this kit will continue to outperform and be a rockstar. I get the hesitation to jump in. Just know that I am buying one myself and building another car in the near future. I have tested and driven a ton of miles on this kit... It is the real deal. I made sure it was designed right and would be a reliable solution.

RJM Trans is doing just fine. The drag race AWD G37 has a unit and so does the carbon Z...

Just because it isnt posted here doesnt mean something bad is happening. Honestly most people balk at the price. RJM may decide to only do them for in house projects given the lack of adoptance from customers. There is a reason shops like fast intentions only do trans builds on cars that they work on.

If you dont want or like the RJM trans there are other options on the market. go buy one of their packages. RJM will continue to push the 7at transmissions with 2 extremely high hp vehicles with TQ expected to be north of 800ftlbs+

Been 2 plus years and nothing to show for it. You can keep repeating yourself ,but if you can’t prove anything, then the bashing will continue. Sure once someone finally can afford a real tune and get the cars up and running I’m sure the platform will speak for itself. Don’t blame the weather for the reasoning behind people not getting there cars up and running.

There are already several cars up and running... Thats what I was saying... Christian, Brad, trey and James all have their cars up and running. the Carbon Z is up and running on its new motor and trans... thats 4 out of the 10 right there.... the rest of the guys are building their cars or have put them up for the winter. Kits went out to customers in august-october... Bobby I believe has traveled and installed atleast 5-6 kits for customers.

Trey was running nearly 700whp (680+) on a stock block! his car is at the body shop and his new built motor is in the works...

RJM Trans putting in the work: this was on a twin turbo car...

Bullitt. At this point why not get someone from rjm to chime in? Are you saying their single person awd g37 customer is more important than all interested parties for their pd kit they should sell to many that they have invested 10s of thousands into?
Thats a very odd business technique.

Oh, please list the $14k stillen build mods required to hit 600whp. Go!

I saw that video when he first posted it and thought "Why he hating on singles?" . Almost 700 is absolutely not going to cut it. I'm in Orlando and Wanna Go fast registration starts March 1st.

Cuz he’s a jackass.

I am not saying that the one car is what keeps RJM busy. What I am saying is that it is a huge time eater. Maybe you should reach out to RJM because you don’t want to hear what I have to say.

As an FYI RJM does more than Motorsports... they do work for medical businesses, aero space and third party manufacturing. The motorsports part of the business is their passion. But it doesn’t keep the doors open, people paid or the lights on.

If you or anyone is truly interested in the kit I have given you the means to contact RJM and ask all the questions you want. Get it from them directly... I talk to Bobby on nearly a daily basis so I know what’s going on.

Name me one build on a vortech stillen kit that didn’t require an entire overhaul of that kit...full supercharger upgrade or rebuild, switch to an air to air setup, or change out multiple parts. Not to mention to rebuild the entire fuel system.... you buy a kit that does 420whp and then you have to tear it apart and replace 70%+ of its components! On a whipple kit you just swap a pulley.

There is a LOT of backstory and behind the scenes grudge matching going on. If you aren’t on Facebook you wouldn’t know about the grudges and **** talking. By the way trey’s car does not have the right suspension in it. Hence, why it is all over the place. He is running some ridiculously firm springs on his coil overs. This leads to the dwell time for weight transfer to be very short and thus not allowing the tires enough time to grab traction. 20” wheels don’t help either. You also forget this is a stock block and was pushing over 600ftlbs! 2600-5200 saw over 600ftlbs! No forced induction bring on power that quickly and that sustained.

Bobby can be at times. However, refer to my other comment about Facebook **** talking as this was the audience. The people he called out were on the live stream.

You must be spending too much time on Facebook. I sell vortech kits as tuner kits for $6000 and you just need fuel and tuning solution on top of that. These kits consistently make around 500whp right out of the box on pump gas. Throw a RFS on and make 575-600whp on E85 all day. A FAR cry from $14k unless you buy your injectors for $7000 a set.

I get that you want to push this product for RJM and I have no problem with that. You said your in it for the community. If you truly are then do not fill them up with misinformed and completely incorrect information surrounding their other options.

How much power do those $7,000 injectors give you?

Did I mention your kit or did I mention the stillen kit. Before we talk about misinformation let’s get our facts straight... my comments are through all the experience I have had helping my friends and community mates try to make the most out of their stillen kits.

Not once did I mention the topgunz kits. So before you get all butt hurt let’s get this thread back on topic. Customer builds!

Guys guys calm down. For those wondering we are still here. We have not been active on the forum for many reasons.

Bullitt is right we are insanely busy wrapping up POs for our customers. We are trying to expand to take on more and to focus some more on the motorsports side.

We also had several customers send us cars to work on which in hindsight we should have avoided doing. These builds have been a distraction from the core of our business.

Also, we have focused on Facebook marketing due to the lack of response here in this forum. On Facebook we have gained more customers and revenue. We are actively participating on the Z pages there. Yes this is a great community but a business has to focus where they get the most return on their investment. With that being said Bullitt has attempted to keep you guys in the loop and share some of the updates from Facebook here.



Topgunz we marketed this kit to go after the stillen kit before you were selling your kit. No one is knocking your kit. However, we would be willing to put a whipple kit against a top gun kit any day of the week. The power delivery of the whipple kit is just insane with more power under the curve the kit is sure to have a major advantage. Maybe we can schedule something.

Bullitt opened that can when he stated $14k for a stillen kit over 420whp.

The kit I offer had goals in mind. Offer a SC kit that is affordable/ecomically friendly. Offer a kit that lands the VQ37 motor in it's sweet spot for Max power yet safe and reliable.
This is especially true on the AT guys (well for engine internals also). The way it ramps in torque is linear and places the least amount of stress on the AT. Unlike "power under the curve" of PD blowers like this one. Which I get it, you can "detune" your kit to keep tq down...but then why spend the extra money?

Goals achieved!


Maybe we can schedule it sometime. Is there a car that is really ready? I'll look for the Mad Max blower sticking out of the hood so I'll know how to find you.

I have no doubt this kit would be fun to own. But for guys with less than $7k to spend it's just not possible.

Anything can be made faster than the next guy when you throw enough money into it.

I have no skin in this game and I just follow because I love the platform, but a spade is a spade. You absolutely did mention the Stillen kit by name. You also mentioned air-2-air conversion, which Topgunz offers the only one, so indirectly you did mention his kit.

Think we need a timeline check here. Topgunz has been sending out his upgrade kit for years.

:drama:

I didn't forget anything. I know it's stock block because he said so. What I did was answer the question he asked several times. ""Where all y'all single turbos?" Tires, springs, widebody , ugly paint. All that matters none. Hell I have 16lb springs on HKS SPs. I don't know how much yet but I guarantee I make a **** ton of torque on C2 cams at 17psi at 10:1 and on E85. Ocala , sign up Mar 1. I was gonna pass because Matt won't go but if they bring a whipple challenge accepted. I'll have Seb step up the tuning and start getting ready. I even told Seb to stop me when he thinks I get close to where 800 should be.
Real **** talk is put up or ahut up.

You know they won’t have a car ready next month. Storms are crazy up north, plus others are only running zero timing or can’t afford a dyno tune,

Hell I think my car will be ready before any whipple hits the streets.

ehm....

If I am correct...Eugene (ByThaBay) already has whipples on the street being safe and sound, lol. Two of them if I remember.

Where them numbers at? I saw the one guy who said it's running but he still has minor issues. I don't have a problem with the platform or the people. But when people start calling out singles either I can do it and step up. Or I can't and I shut up. Calling people out means you're ready right now. If you're not then stay humble. Again Ocala sign up March 1st. They have shop resources, all I have is my bank account and thats it. A shop should be able to make it happen.

I duno. I'll ask Eugene. I'll get back to you though! I'm sure he has proof somewhere xD Either that or I'll ask the person who's getting his whipple tuned by him! Be back soon!

As Bullitt has correctly stated there are multiple cars on the road. I find it funny that some of you only care about dyno numbers.

Bullitt has also correctly stated that stillen was the only other turnkey supercharger kit when we started this. Yes topgunz had his a2a conversion which to be honest doesn’t make it a supercharger kit. Yes topgunz did eventually make his own kit based off the stillen bracketry. And while yes it is a budget friendly option it has limitations. You will have to upgrade the centrifugal supercharger to make the higher hp numbers we are able to achieve with just a pulley change. This isn’t knocking the topgunz kit at all but it has its place as a budget friendly option. We are bringing the best bang for your buck if you want to make power. No need to modify kits just change the pulley and switch maps.

We have several cars on the street. The kits are doing just fine. You can ask our customers their thoughts on the kit. Brad, Christian, trey and others are loving their kits. Mike even gave several stillen kit owners rides last year at zdayz and their responses are priceless.

Nothing like positive displacement power!

I have nothing against topgunz or his kit. As RJM stated it’s a good budget kit.

Thank you Bobby and RJM for backing me up.

I find it funny all the hate from people who have no experience with the kit. This whole thread was to share the information that users of the kit have had with the kit. But instead of asking legit questions I have gotten a good bit of flack for trying to share what many people were asking for.

I know some of our members don’t have Facebook accounts that’s why this thread was started in the first place. I don’t have to share the updates...

Brad has a YouTube channel “ageekyguy” and he has been actively given an honest review of his experiences with the kit. From when he ordered to his tuning has been going. He updates very regularly. He is very direct and honest and he is learning a lot about his car. He should be in the mid 500’s on hp and mid 400’s on tq limited due to his stock trans.

It's true. The TG kit will Max out near 600whp (well some have pushed it above that). Beyond that you will need to step into a different forced induction kit, built motor, and built transmission. The $ per HP starts to diminish at an astonishing rate.

Power costs money, absolute power will bankrupt you. :mad: If you chose to go down that rabbit hole. You end up like this guy. Been there with my big blocks.

I know all about this! When you could have bought a new Z for the price of your motor...

Doesn't take much to push it past 600. 😎

Amen to that.... Then you wonder how long it is going to live and if you did everything just right.

The other part of this equation is how long you planning on keeping the car.

The only way you can make out is to keep the car FOREVER!!!!

I have 2 of those type cars laying around the house. LOL One in the garage and one in my shop.

Guess I need to bring my photo album to Zdayz.

You have a true bang for the buck kit. This is why I designed the whipple kit with RJM. The idea was to make going forced induction easier. Get into a kit and the kit be something you can grow into. Start out with 500-600whp and then when you want to go big you only have to worry about the motor and trans. No new supercharger, no new turbos or new housings. Just build the motor and trans and let it eat. Yeah it’s more expensive than your kit by a good margin but every component will last the life of the car! The pump is rated to a life that would equate to over 100k miles! There isn’t a “cheap” part in the kit and thus why the price is what it is. Could corners have been cut yeah but it wouldn’t be as solid of a kit. Everything was thought out from longevity to maintenance and performance. I am just glad some guys get to enjoy it and I can’t wait to do my build!
