Just as I was looking at the stillen kit you give me the whine I loved when I drove the ZL1. Find me a good hood option and Im in, heck ill modify my OEM hood to fit if I have to. Let me know how this rounds up because I may be ordering in the next few months if it works well vs the stillen kit

On CARB...

RJM is going to be working with Roush on CARB approval. Their vast experience and testing capabilities makes them the best partner for this process. The main delay is that roush has gone through an audit earlier this year by the CARB board. This happens every once in a while. Due to this audit they cannot do certified testing on behalf of CARB.

RJM has all the documentation and is consulting roush for advice on CARB. Once they clear their audit RJM will source a car and send it to roush for testing.

This is a costly endeavor for RJM. So please be patient they aren’t as big as stolen but the kit is extremely solid!

Another customer's car put down 617rwhp and 408ftlbs on 12.5psi and e85. There is a ton of room for his car to go once he upgrades his oil cooler.

So far we have about 4 cars running this kit on the road now and several more on the way.

bullitt5897 09-22-2018 03:18 PM

Customer’s car is stock block and a full stage 1 kit with the race heat exchanger upgrade. He has the fast intentions flex plate and RJM triple disk tq converter and level 10 valvebody for his 7at.

He will be making the switch to the RJM fully built transmission soon as well.

RJM now has pulleys for the following PSI levels: (*note: these are calculated PSI levels)
4.2 = 8psi (Mid to high 400whp) - tested and proven super reliable
4.0 = 11psi (500's) most people pick this one
3.9 = 13psi (500's - 600's) Tested and proven to make 600's and mid to high 500tq on e85
3.6 = 15psi (600's) new pulley
3.4 = 17psi (600's-700's) already tested to make 700's and 600ftlbs
3.2 = 19psi (800's) new pulley
3.0 = 21psi (900+) new pulley

RJM has two built cars in the shop about to run the 3.0 pulleys.

RJM will be stocking these pulleys and you can choose which one you want when you order.

RJM also has told me they have a few kits on the shelf for fast turn around. only the heat exchanger and supercharger need to be ordered.

bullitt5897 11-09-2018 01:30 PM

Technically speaking we can run the lower pulley up to 6.5" over drive pulley (15%OD) and with a 3" upper pulley run ~ 30-31psi... this should theoretically net well over 1000whp+ Testing is expected to be done on this.

ZontheRocks 11-09-2018 01:40 PM

Would it be possible to have a thread similar to the Fast Intentions and others that have the builds for the kits in one place to review build data and dynos, etc.?

Something along the lines of......

Customer #X
Ordered Stage 1.5 with the following upgrades....
Pics of install
Dyno Sheet
-------------
It's hard to follow this product, IMO. I would think that with 10+ installed we would be seeing increased marketing (by way of owner testimony/pictures and experience) on the forum. One thing to see promotion from the seller. Whole other ball game when its from the customers.

goeagles11 11-09-2018 01:58 PM

+1 ^ Where are the driving videos or customer dyno charts?

bullitt5897 11-09-2018 02:01 PM

Of course. However most of the customers arent even on this board. Most of the media you guys are requesting is actually been posted on facebook and on the RJM facebook page for months now. I can see what I can do to compile that information into a single thread for you guys.

There is also a private group for the Whipple owners on facebook. I can share some of the pics, vids and experiences from there.

So you mean to tell me there is a super secret Whipple clique? That's all the selling point I needed!

Yes, please. I do believe that we on the forum are interested in the continued development, production and execution of RJM P.D. Supercharger kits. Both from the manufacturer/company marketing standpoint AND the direct customer.

Not possible to have reviews written and copy pasta to here on the forum?

*Save $500 on your kit and write a review/testimonial that we will use to promote (and get others to drop coin!)*

bullitt5897 11-09-2018 11:29 PM

new thread posted and I threw in a few customers cars. there are several more including one built by cruizin auto in north carolina a few months ago.

EZT 12-30-2018 05:00 PM

Bullitt, any update on the hood? I’m trying to coordinate with some paint and body work, so I can have it done all at once. Then save for the whipple.

They keep coming up with excuses, it’s winter time, kits are new, something broke on my car. But I’ve seen video’s Of cars idling in garage, and data logging on the highway

phreak9i6 01-08-2019 01:56 PM

My RJM kit is in the garage waiting to be installed. Hopefully when the car gets back from the audio shop in late feb I'll have the RJM whipple on and some updates for everyone.

The build quality is top notch on all the parts/brackets/etc, I'm amazed at the craftsmanship.

Elmo370z 09-21-2019 08:57 PM

Habahaha. So much for these 1,000 hp whipples

bullitt5897 09-26-2019 03:51 PM

Rich’s car is being tuned right now. Lots of changes and custom work outside of the kit went into this car. RJM was relying on a tuner but that tuner was not making themselves available. I could empathize with rich and offered up one of my ecutek cables and dongles and tuner I am working with offered to upgrade rich to ecutek. So right now Bobby has been doing driveability tuning with Eugene Turkov. The plan is to have the car on the final dyno next week. I would have to confirm with RJM though.

Most of the delay on this car has been from relying on third party shops to do work. As most of you know RJM is a parts manufacturer not a performance shop. There are no lifts and no power tools to work on cars. It’s a cnc manufacturing shop. Additionally, RJM took on another build the awd g37. Rich’s car has been running and driving just fine for months sadly the tuning situation was not expedient and should have been. The awd g37 is an insane build with multiple shops touching the car. It’s currently at another shop getting the interior put back in and then it will be tuning.

That’s as much as I know meanwhile there are several guys with the kits on their cars.

bullitt5897 09-26-2019 03:58 PM

Per Rich’s request we aren’t looking to top the kit out. We will tune it and dyno with a small pulley but rich will be taking delivery with a larger pulley (smaller pulley and belt included in the car). Why? Power delivery... most of you guys haven’t been in one of these cars let alone driven one. The power deliver especially at higher psi comes on very quick and if you are not ready for it you will spin the car out with relative ease! With the pulley that is on the car now I believe we could see 800whp+ relatively easy. The car was on its way there when we pulled it from the dyno to save his titanium exhaust. With his new free flowing exhaust I am excited for the results.

I know rich has waited a long time for this and I can’t wait for him to take delivery of his car!

And the other 8-10 owners that picked up the kit?

Many have... I just don’t have their sheets and most of them aren’t on the forums... so not much I can share there. The carbon z on stock motor and 7at made 540+whp and 400+ ftlbs @12psi since day one. The car now has a 4.2L built race motor. As soon as I have final numbers I will post it.

I would really like to admire your product. I do admire the new design and the engineering that went into it. But from a sales perspective you have to understand it's in your best interest to provide proof of claims, especially when working with a guy widely viewed to be untrustworthy.

I agree with 100%^^^. All these claims, 1000hp, built race motors, etc.... this thread is like beating a dead horse. Lot of pumping of the product with no backing.

In reference to boosted VQ’s, there are enough folks on here with social media and smart phones to capture any footage to link here. You think with a untested and expensive product you and Bobby would keep in close contact with shops and/or DIY’s in regards to installs and most importantly dyno numbers which you have failed to provide beside the z days car. That 540 you claim was a small spike at the very top of the graph, it’s all documented here on the forums. In reference to built race motor, isthis car actually going to be raced or just mall crawl around like most high HP VQ builds? When is soon, soon has been going on 4 years now. This thread about the whipple kit is been in a coma since it’s release date. I get things take time, but I suggest quit posting until you have some concrete data to show and explain any question folks have instead giving beating around the bushes type of answers. We don’t care about what your calculations say or what type of data this or that provides. With someone pumping this product so much as running a TT kit and lack of data and the hibernation of people not getting these kits installed is a huge “Red Flag” for the wise

Dyno graphs were provided day 1 of the preorder. it seems people forget that.I would love to share the graphs of the carbon z when it was on the dyno last however, i am not in possession of those dyno sheets. I was on the phone with bobby when they were dynoing it and I know it was making well into the 600's on pump gas and a lot left in it.

Again, Bobby is street tuning with Eugene (remote tuning) so once they have the drive ability done eta hopefully mid week. then we will be getting on the dyno immediately. Bobby wants this car back in Rich's hands. It does no one any good sitting in the shop...

Where is it that you get the idea this is an untested kit?

That 540whp would have been higher if we weren't on a stock block and trans... the redline was actually limited to preserve the transmission. If you recall that Zdayz we were giving people rides and beating on the car.

4 years???? the kit was released june of 2018 for preorder... which goes back to your comment of untested. we were testing and revising the kit for over a year...

You are the type of guy why people dont post and the reason the community gets toxic. Talk to one of the owners. Brad and Ken both have thousands of miles on their kits with no issues. Both can speak to the power difference compared to the stillen based vortech kits.

If I had a spare Z I would do this over a weekend and give you the numbers your asking for. However, I am down to one Z and when I get another I am putting my money into building one of these. Thats how much faith I have in the kit. I am desperately waiting to get another Z to build with this kit. Ask anyone who knows me personally I wan to do this more than keeping my TT Z!

So Again, the carbon z is finishing up remote tuning this next week. once that is finished the eta to dyno is the following week. I have been 100% honest and transparent about this kit. I am one of the lead designers on it. I havent been pushing or even trying to sell the kit on the forums.

He has a cut hood smae as brad who has won a ton of car shows. I designed a hood cowl but finding a reliable body shop to make it has been the bane of my existence. 4 body/carbon fiber shops and not one person has provided a plug for mold yet. I have even provided them detailed cad files to work with. I am more than happy to share that with anyone who wants to have one made for their car.

Who is pumping the product. I am simply responding to comments and questions... do you see me or anyone selling the kits on here? No you dont. What claims? the fact that customers have hit 500whp with dyno proof in the OP? the fact that the Blower and components are engineered and rated to 1200whp? those arent claims but actually documented facts.

The blowers used are the W175AX "high pressure" units. what does that mean? well the center catridge is designed for higher efficiency for 17psi and above. this means the blower hits softer down low saving parts and as a person grows with the kit they will experience better power gains at 17psi and above. The standard cartridge unit peaks out around 17-19psi... where as the "High pressure" unit has already been documented to make 28psi on other applications and likely higher on our VQ motors given our pulley configuration.

No one is pitching this kit has made 1000whp. And in a few weeks more results will be posted. I will make sure you all get an opportunity to hate on another dyno graph. funny thing is the guys who have bought this kit are mainly 7AT owners. only 2 6mt owners have bought the kit...

For those that don’t know. Christian posted a video of his latest track day weekend with the car. It took a while but it’s up on Facebook now. I don’t have a way to share it here.

Zoey_the_Z 09-30-2019 06:27 PM

TLDR, my car made 400/320 on a mustang dyno last october on a less than stellar tune with conservative timing. Now, the car has been completely retuned and we are working on fine tuning the car using logs from hpde events. As far as power goes, I'm unsure. It feels a lot more stout than it previously did at "400/320" but take that with a grain of salt as I am still on factory clutch/CSC.
