Full CJM fuel return system/billet rails with 450 pump and ID 1300 injectors. Also will have flex fuel. Starting out with just a 93 pump gas tune then bringing in the E85 afterwards.

Hoping for around 550wheel on pump and 600 on E85, I feel like that is moderate compared to what Topgunz says this is capable of. Currently have all parts ready for install other than Topgunz Kit.

Nice, will you be posting your install and results on here?

I can only get 91 in my state, and anywhere from 400 to 450whp would be fine for me. I don't want to push the 7AT too hard.
I had a 2016 GTI that lost it's DSG transmission at 20K miles with a Stage 1 tune, those DSGs were supposed to be "bulletproof" but that was an eye opener!

I'm looking to see the outcome of a kit that is installed on a 7AT car, tuned primarily for 91, runs full air intake filter and will be daily driven.

I know most people getting this kit will be installing it on upgraded 6MT cars and going all-out (jealous!) but I am hoping that someone is going for a more restrained approach on a 7AT car that I can follow.

I have mine installed on a 7AT. Just finished and working on tuning.

Do keep us posted, please. Next year is my make / break for whether I pursue the VR 7AT swap, or stay stock with upgraded flex plate. Good luck!

You get yours going? I’m 90% complete with install on mine also on 7AT.

In other news, we just sent a kit out the door to a big name shop that is going to push this thing hard. I cant wait to see what they can do with this monster. Buckle up!

OK, so no buyback program. I get that. But what is the pricing and availability for the parts needed to convert from an ACE kit?

INB4 he refers you to page 15 post #224

Yes, I've seen that. It says basically buy a whole new kit and sell what u don't need. Of course, thats always been an option, from day one. I'm trying to understand what the cost would be to get just the parts needed to convert, similar to what I did in converting from the Gen 1 kit to the Gen 2 (ACE) kit.

It would be $5150 to send out everything you need to turn the ACE kit into a Rotrex kit.

Remember, this is an entirely new head unit (MSRP $2800) with the oiling system ($3250 msrp total) , new bracket with all new pulleys and new belt setup. New aluminum cast driver side intake, charge pipe, SC intake with filter, boost control hardware.

TopgunZ would it be possible to combine the boost control function you've incorporated in the Rotrex with with the SpecialtyZ solenoid to control it through Ecutek? I'm not sure if it's a wastegate/ebc or whatever, so not sure what is/isn't possible with it.

wastegate post
As a wastegate is should be controllable via the same methods you see for TT setups i think.

Thank you Aaron.

It is not a WG. We control the BPV with a MAC solenoid via hijacking the EVAP purge valve signal going to the ECU which can then be controlled through Ecutek (map switching using your cruise control buttons) or by a standalone boost controller like the Innovate SCG-1.

If your going boosted the SCG-1 is really your best option as it displays Boost, AFR and allows you to dial in boost on the fly, in an all-in-one gauge.

SeeThruHead · 08-06-2021, 10:15 AM

It can't do boost by gear tho which is why people want to connect it to ecutek no?

EDIT: can you clarify how the "BPV" (bypass valve?) operates? does it have springs? does it have top side and bottom side air inlets etc...? (ie in what way does it not work like a wastegate?)

TopgunZ · 08-06-2021, 02:40 PM

We did not do this so you can use boost by gear. We did this for its performance benefits. When you spin the blower faster then bleed off the boost after you hit your desired peak PSI then you move the entire power curve to the left. Meaning we will have way more HP and TQ lower in the rpm band at 14psi then anything on the market. It also allows us to offer a supercharger that can run a "daily" map at 14psi and then a "kill" map at 18psi. Or a daily of 12psi and a built motor with 20+ psi.

Otherwise you are always stuck to the PSI of the pulley you have on.

The BPV just opens when its told to so if you set that at 15 then it opens at 15 and dumps the excess charge air vs a WG dumps the excess exhaust.
