I am not sure when we will have 93 numbers. However, I am sure you have nothing to worry about. I can GUARANTEE this will make more power on 93 than any other supercharger option you have been considering. Really, what would be the reason it wouldn't even if you ran with a dirt ingesting kit?

The supercharger is more efficient, the intercooler is very efficient (24*F temp rise at 21psi! ) , it can control boost to dial in exactly where you make power with timing vs boost. Just looking at this kit can tell you it will dominate any other SC on 93 all while filtering the air.

And the hummm and whine of this unit puts it in a whole new realm of sound vs the marbles effect.

How much boost can we run with what comes with kit? Or do we need to buy a separate electronic boost controller ?

The kit will come with 5 wastegate springs. Dial in whatever you want with those. You could add a manual or even better electronic boost controller to dial in on the fly. Revolutionary in the supercharger industry. No kit on any platform has offered this.

Best part is you can buy a Specialty Z boost solenoid wiring kit, a Mac boost solenoid and control it all through EcuTek, and monitor with the Bluetooth dongle. 😎

Any reading on how these all interface and work through the tune? Does it just eliminate the need for the boost controller in the cockpit?

Nevermind, I think I found here: https://www.full-race.com/store/borg...ol-solenoid-1/

That was already answered on the last page or 2 pages ago brotha.

I currently see the kit on the website. Does that mean is it currently in production? If so what is turn around from order place to it being shipped? With its current configuration( pulley ratio, etc ), what is the expected boost level and rwhp it is expected to produce?

What is your definition of "in production"? You won't see customers running the kit already. It was literally just announced as you can tell from this thread.

On https://www.topgunspeedworks.com/nis...percharger-kit it says:

"We have many of these components being fabricated but will not be able to assemble and ship kits for 6-10 weeks."

So expect up towards 10 weeks, I guess, before it'll be shipped to you.

My local tuner here in Sweden has just put down an order for me. Really looking forward to it. Been waiting for a Topgun kit since November last year. :eekdance:

Swedez summed up most of this. I placed a dyno sheet for boost and rwhp on the first page. Basically, you can make anywhere from 400whp to 800whp. It all depends on what you want.

So basically it is a 700+ rwhp kit that is being sold and if you want less rwhp you have to buy a external wastegate, boost controller, and then either manually set the boost level or control it electronic ally with a tune. Looks like EcuTek and not UpRev can do this through a tune.

Realistically this is a $9300+ kit. Base supercharger kit, fuel injectors and connectors, return style fuel system, boost controller, electronic wastegate, EcuTek license & tuning, plus X amount of unanticipated things. Does that sum things up?

A wastegate comes with it with 5 springs. It's on the listing on the site. You just put whatever psi spring or combo of springs to hit your desires power level. If you want to run on the fly different power levels then an in cabin boost controller is needed or wire into ecutek. But you would still want an afr and boost gauge so you might as well opt for the innovate scb-1 which is those plus boost controller all in one for $320.

It's hard to put a dollar amount on it since everyone wants a different build and fuel required to do that. You can get fic injectors for half the price of ID...etc..

TOPGUN SPEEDWORKS ROTREX SC KIT Vs. competition SCs.

www.topgunspeedworks.com

Rotrex: Record breaking 556+wtq and 22+ psi out of the box with a full filter
Competition: V3 requires overspinning and a sand eating turboguard for only 15psi.
Rotrex:Full filter that can be cleaned in 5 minutes.
Comp:Dirt and sand ingesting turboguard..or motorcycle filter that restricts psi to 12 and requires the removal of the entire supercharger to clean.
Rotrex: Stock plenum
Competition: Stillen plenum requiring MAF and TB extension harnesses which are extremely problematic and known heatsoak issues
Rotrex: Purrs like a kitten and whines like a F1 car
Competition: Marbles in a coffee can due to gear backlash
Rotrex: Ability to dial in exactly what psi you want to run with in cabin boost select options
Competition: Choice between 8psi or 9psi pulley. Manually removing them to swap.
Rotrex: Most affordable supercharger kit on the market that can break 500whp.
Competition: More expensive.

***We are just scratching the surface on what this kit can do!***

And don't forget to add, Vortech's customer and technical service are one of the worse to deal with.

To be fair the old kit is easily possible to hit 15psi with that tiny filter, seems most people can't figure out proper belt tension to save their lives. I was at 15psi with a fresh filter, now after a year of almost daily driving the car without cleaning the filter it's only down to 14psi.

Anyways, the new kit looks amazing, good job. Love seeing the constant progress being made with this platform.

Can you prove/validate your 15psi? Pulleys, SC rpm, SC trim, SC bearing upgrade, accuracey of boost gauge, etc? How do you know people making less than 15psi is due to belt slip? How did you figure out and know "proper belt tension"?

Sure do. I can grab datalogs from my laptop tomorrow if you are still interested (rather do this via PM's though, just remind me). The big thing was swapping the supercharger to the RPM belt, the "normal" one is a constant losing battle between trying to tension it just for it to stretch and be loose again. Not one problem since.

I wouldnt say "easily possible" since I have never seen anyone make 15psi with it. Not saying you didnt but there have been many of these kits sold and I have never seen one make any decent power with that filter on.

What is considered almost daily driving? 10,000 miles? That means every year you have to remove the entire supercharger and reinstall it to clean your filter. Also, I see that filter gets completely smashed from engine movement. Even after cleaning it I am pretty sure it will not bring in the same psi as it did when it was new. It physically loses surface area, something it cant afford.

Plus just the fact that knowing every time you drive your car it is losing psi/power is kind of strange.

I know I am calling the kettle black here since this was my design and I appreciate the feedback to help the community understand facts. (unlike facebook)

In your below comment you have stated you had to modify the kit in order to gain boost. When I say 12 psi that is because that is what the competition sends out to the customer. Yes its possible to modify it to make more boost. You could have done this by overdriving the head unit even further also.

The point is "here is what you get when you order a Rotrex kit Vs. here is what you get if you order the competitor kit". Nothing needs to be done to the Rotrex kit at all in order to make more power than most people know what to do with instead of constantly modifying and trying to figure out how to make these Vortech kits make more power.

I also forgot to add:

Rotrex: 50,000 mile service (oil change) Once every 3.5 years
Competitor: 7,000 mile service (oil change) Once every 6 months

Don't get me wrong, I am in no way trying to diminish the new kits capabilities. I know it will be superior to the previous kit(s) in virtually every way. I despise that stupid filter, I have offered several shops good money to come up with a custom solution to it and none of them even wanted to try.

Ok, so this would be my first major purchase for my Z. If I can't do 700+ due to having stock internals and block, what all do I need besides this kit? Trying to figure the total cost for parts.

Did you read the product page?

It mentions:

91/93 OCTANE MINIMUM REQUIREMENTS - up to 500whp

- 1000cc injectors (Highly recommend Plug and Play Clips)

- 340lph pump with install kit and voltage stabilizer kit

- Ecutek package (Interface, deskey, license)

- 4 bar omni MAP sensor

- Tune required (We offer a base or remote tune package, see main page)

(All components listed are available on the main page)

....furthermore it’s typically not the HP value that destroys the motors it’s the torque getting beyond about 500wtq that blows the connecting rods through the block. It’s like an unwanted axe throwing contest inside your engine, you’re just waiting to see which one of 6 punches a hole first. Superchargers in general have a linear curve so if you hit 500wtq it’s at the very top near redline, your motor is spinning at a high RPM so it’ll wear the motor out less quickly. On the flip side, twin turbo setups make torque very low in the RPM band which puts a lot of turning/twisting force on those con rods which is how you end up having a bad day if you just “tune for max HP”, disregard the fact you’re making 550+ tq, and give ‘er a full send or 2, hope you got $$$ for a built block. Then again, the torque pulling you like a freight train down low is what people love. It’s all what you want to do.

Still need to see a dyno or driving video of the TG C39-110 kit.... I need to hear some S/C soundsssss :driving:

What will this kit sound like with regards to the blow off of excess boost? Will there be a way to completely silence it?

I know on your other kit there were methods but i can only imagine the sounds when you only want to run 10psi but its making 23.

You will likely need a very beefy clutch upgrade for that much power.

Sent from my Pixel 3 using Tapatalk

Are there any clutch recommendations if I want to make 500 WHP with this kit? I have roughly estimated a maximum of around 500 torques at the crankshaft. Zspeed has a stage 2 clutch rated at 480 but he reports some safety range included in that.

Sent from my Pixel 3 using Tapatalk

Call up Joe at ZSpeed and he’ll give you the hookup. I believe their Stage 3 clutch setup is the one I see a lot of twin turbo guys running. Good for them, it’s god enough for me! Plus, you’ll want to do a CSC delete since you’re already there, may as well. Oh, and get an RJM Clutch pedal cuz the stock one is absolutely garbage to put it nicely. That helper spring is trash.

Southbend stage 3 is a great clutch. It's full face so it drives like stock, it's just a little stiffer and will hold that power and torque.

If I was to order the kit today would it be included functionally? I know it isn't tested yet but I would want to pass a visual inspection under the hood which should be enough for me.

Sent from my Pixel 4a using Tapatalk

Could it pass Smog? Yes. Could it pass CARB? NO, The MAFS are still in the intake pipes right before the throttle body. IN order to pass carb you would need the mafs in the intake pipe before the supercharger. Which is totally possible. I just havent gotten that far yet.

But the Fast Intentions Twin Turbo guys have been running over 550wtq for years - some at 580wtq.

Stillin plenum with A2A setup....15.2 psi with a v3 SCi trim 2.87 serpentine pulley, 3.47 jackshaft pulley, 2.95 supercharger pulley, K&N filter. Validated through EcuTek data log. I’m sure if I had an Si or upgraded Ti trim and no filter it may be more...but that v3 can’t take that abuse for long before the oil slinger is destroyed and is eaten by the gears-trust me on that.

I have also have Stillin plenum with A2A setup but about 2000rpm slower with my pulley sizes (checked with Vortex calculator), but with upgraded Si trim and only get 10psi. I'm also running the "standard" belts on serp and SC. Are you using the Gates "RPM" belt(s)?
I have ordered these to see if they will help with boost, otherwise I have no idea how you could get 50% more boost than me, but would love to know.

https://i.imgur.com/Z9ihOTR.png

It does happen. I have nothing more than a stock v3 SI and an RPM belt on the supercharger side (planning on trying to add one to the serp side as well as an experiment in the near future). I really can't stress enough how much of a difference that RPM belt makes. That normal belt stretches VERY quickly and begins to slip as a result. The last dyno run I did with the "normal" belt was at 10.5psi because of how bad it got.

I don't think we should continue to derail Topgunz topic with this old kit talk though.

True. Lets get back on topic here.

We are going back to the Dyno on Monday and will have additional boost level logs to share. I think we will do a 15psi log, 20psi and then also one where we remove the filter system to see where the kit can go. However, we will most likely run out of fuel again so we will chop throttle at 100% duty cycle and then superimpose the boost line to show what the kit could do if someone were to string it all the way out.

I was talking to a guy on the phone last night and he was saying that he was trying for the NA record and was taking his motor up to 8500rpm on the dyno. He is now going built block and this kit. Cant wait to see someone run this thing up.

Stock intake manifold? I recall there being problems where the stock manifold can crack at those higher boost pressures.

It should last at that. Mine started leaking after a good day of running 25psi of boost. That boost pressure was at 4000rpms all the way to 8k.

Yes stock manifold.

Do you have a picture of one of these cracked ones? I think its more of a scare tactic for people to buy unnecessary parts and spend money.

WRONG, they don't crack. They start leaking at the back. 20psi should be fine. I ran 22psi with no issues. 25psi, forget it. If you get up in the 20psi range that is build
motor territory anyways.

[QUOTE= I don't think we should continue to derail Topgunz topic with this old kit talk though.[/QUOTE]

Agreed, just wanted to relay how it was achieved. That being said...I would MUCH MUCH rather move to the rotrex setup. Much easier to reach HP #’s(if your chasing that), the efficiency of the supercharger to me is one of the biggest pros; plus I HATE the Stillen manifold...I have the jx/qx60/maxima(whatever you want to go with there) T/B’s and adapters that absolutely do not fit because of the location of the Stillen mounting for the stock t/b. Having the stock manifold would just be that much better, especially with the bigger t/b’s. Super impressive Topgunz-keep up the fantastic work!
