***Topgunz ROTREX C38R Supercharger Kit***
 

Topgun Speedworks is consistently striving to create the best supercharger kit on the market. We are in the process of releasing an all new supercharger kit for the VQ37VHR platform utilizing the Rotrex C38R-112. This kit will have numerous benefits over the ACE kit and make more power than any kit on the market.

Utilizing the Rotrex C38R we plan to achieve the following:

- Increased HP/TQ
- Increased efficiency
- Decreased intake temps
- Decreased Maintenance (Oil changes every 50,000 miles vs 7,500 miles on the V3)
- Quieter operation (no more harsh supercharger gear backlash or ""marbles"" effect)
- Optional On the fly boost control (In cabin)
- Optional full size cone filter in bumper with Straight through design.
- Optional full BOV recirculation with PCV ingestion (Emission and CARB compliancy)
- Optional pre Supercharger MAF placement (Emission and CARB compliancy)

To be somewhat comparable I went to Vortechs website and pulled up the massive Ti supercharger since it is closer to the power range of the C38R. However, as seen by the compressor maps below you can see how the C38R efficiency island is much, much better than that of even the Ti.

TEASER!!

Update 4-07-2021

Topgun Speedworks ROTREX kit release!!! With a FULL FILTER!!

708whp!
556wtq!
21.5psi!

All at only 7000rpm rev limit!

Stock block!

We ran out of injector. We were at 107% injector duty cycle at 7000rpm. Conservative tune.

This kit will hit 23+psi and make 750whp pretty easily with more fuel. With a full filter! We need a built motor to see what happens with a turboguard.

This kit will be able to bleed off boost for whatever power you want to make.

Still the most affordable supercharger kit on the market!

Tuned by the best... Eugene Turkov

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: 50,000 mile service (oil change) Once every 3.5 years
Competitor: 7,000 mile service (oil change) Once every 6 months
Rotrex: 10 rib supercharger belt, no slip serpentine belt, 10 second tensioner adjustment design
Competition: 8 rib supercharger belt, serpentine belt slip common, most guys remove the supercharger to tighten it down
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!***

Reserved Spot #2

Finally! A kit with a viable option for a real air filter!

Congrats Aaron. Looking forward to seeing how the Rotrex performs. By all indications, it should perform very well. And you don't have to deal with the sh1tty customer/tech service of vortech.

Right on man! I haven’t logged into the forum in ages, but this setup may be just what I’ve been waiting for. Will be a lot more friendly for a daily IMO.

Boss! Now he comes out with something I been saying for years

So will this replace your Ace kit or will it be another product? I can’t imagine a major price difference between kits.

Nice to see conaiderations for CARB/emission compliance. Are you actually going to get the kit CARB tested for those in california, and elsewhere with strict emissions compliance?

Also what are we looking at in terms of boost figures, and will there be an option for conversion from your old kit?

Well, you have my attention for sure.

Damn, that's nice.

Subbed!

In for NSFW engine bay porn. :yum:

Any durability testing data you can share on the kit?

It will replace the ace kit. No sense in offering an inferior product.

Price will be similar. Also, the most affordable air SC kit on the market. $ per HP will be superior!

Actual carb approved will be a goal.

Boost will be posted after Dyno testing in a couple weeks.

An ace kit can be converted to this with a bracket, head unit and driver side piping swap. I might do a buy back program.

I want this on the Dragon Z lol

Mother of God

I should have never checked back in after being away for so long. Looking good Aaron.

Upgrade time

THIS is what I’ve been waiting for. I’ll accept this as a sign that I need forced induction.

Good to see the Rotrex being used on the platform . Us Honda J series guys use it as our primary big power kit however now many have it as people don't really mess with Honda v6 stuff. The creator of the kit used the rotrex due to its size (these blowers are small af), it's efficiency and potential. I have a c38r, not pushing it all the way. Looking forward to what this is capable of in this platform

How will the "Optional On the fly boost control (In cabin)" work?

Probably a wastegate and ecutek boost controller

I wonder if the boost controller can protect the 7AT from boost while in the taller gears?

I'm not sure if Ecutek has boost by gear for the 370Z yet

I was also considering other ways of using vehicle speed/RPM programming to limit boost also....

Just spit-balling, I heard rumors that the 7AT doesn't like boost in higher gears. Not something I am sure needs to be chased yet.....

That's way above my pay grade ;)

We will know by the end of year; as IPT has mine & working it over,,,knowing there’s gonna be 5th & 6th pulls on it @800whp+ :ugh2:

I dont want to put pre-drawn conclusions on the whp this kit will make. 800whp is a very high number. That is almost 1000bhp. Either way this kit is going to put a lot of guys in the "need a built motor" area if they want to maximize the kit and also have a reliable setup. However for guys that want modest power and not place the stock engine at its limits then we have options for that also. This is why we are offering the kit with a boost control option. It allows the user to chose when they want to really put power down and adjust it back for daily. Auto transmission guys will benefit from this immensely. Also, a benefit is that it will shift the curve to the left of the graph where we will notice higher power and torque lower in the RPM band which makes the car...faster.

Again, the goals are that we will offer the highest horsepower, out of the box supercharger kit available and we have seen the ACE kit making 650whp on E85. Also, this is the only high horsepower kit that will offer a full filter setup while minimizing power loss.

We are going to dyno the kit with just a turbo guard on the first few pulls to see its potential and then put the intake and filter on and see how much we make. I am guessing it will be around 2psi loss but I am hoping that at even a loss like that it will still make more power with filtered air then all these other SC cars with no filter at all.

:yum:

Why can't we do this with the ACE Kit?

You can. I've been running a wastegate and electronic boost controller for a few years

Patrick, I remember about 3 years back when I explained to you how to set that up. However, I have a new technique which modifys the BPV to achieve the same result without the added cost of a WG.

Engineering win! I'm sure it will be copied soon after.. again. But it will still benefit the community.

I remember it very well also. For my application, probably the best sc mod I did. Thanks for the help on that.

Your new technique sounds interesting. And of course it will be copied, just like the wastegate set up has. Actually, I'm surprised more haven't done the wastegate.

You haven't seen the WG option because the current mainstream setups can't produce enough boost to take advantage of those mechanics.

Enter the C38R-112...gives us a better reason.

The Vortech V3 just can't handle being overspun to be able to produce that kind of boost. I like the V2 but when we couldn't get the Ti to make the power it should have been capable of and the lack of support from Vortech, I've decided to go tt's instead. Of course I made that decision prior to you releasing the info on the Rotrex kit.

Well I could of told you to wait

Wait for a blower that hasn't as of yet proven to make power on our cars?
