***Topgunz ROTREX C38R Supercharger Kit***

SwedeZ

I have yet to have mine built. It was supposed to happen before the winter but different things got in the way so now it's planned for April, my builder/tuner has promised. Fingers crossed.

is there something specific you where hoping to see that you haven't yet?

been running my kit for about 2-3 months now.

The max potential for the kit seems to have been tested and hit already assuming you have supporting mods fueling, trans, engine etc... is about 575WTQ/800WHP.

the design of the kit and method it uses to control boost lets you have all kinds of tuning and power delivery options depending on how you want to set it up.

but at the end of the day its still an FI / SC kit. Not sure what more information people are still looking for?

Received my Rotrex kit a week or so ago. Will be starting to remove ACE & install new one soon. Scheduled for Dynosty tune in late April. If only work & house projects would GET OUT OF MY WAY.

I just ordered mine on Thursday, can't wait! Funny how things change i remember posting a few months back that I wasn't going to boost this car.

The obnoxious guy on facebook blew his headgasket with the kit, but he probably had it stupidly turned way up.

TopgunZ

I asked him what happened and he said he had a very high mileage car and was running high boost.

Yeah I don't use fb or Instagram. This is as close to social media as I get, and reddit I suppose. I'll be posting updates as I get everything installed. Will be running a cjm fuel system, 1300 injectors. The plan is to take a week off work and bang out everything, hopefully drive it the following Monday.

AT eh? Curious if you plan to run boost by gear or have built your trans?

To those of you with either kit, what have you done to beef up the automatic transmission? Are you limiting power to a certain level? I want this kit but not sure what to do with the transmission. Not interested in level 10 . I want input from actual owners. Thanks

Besides a trans cooler and an ATF to coolant heat exchanger, nothing at the moment. Running 11psi on E40 at the moment. Holding fine for now.

Debating on my options, if your end goal isn't over 600whp then the VR30 trans swap is a great option.

they can make it pretty much a plug and play direct swap over.

Is that the stock heat exchanger in the radiator you are talking about, or an additional atf to coolant one you added outside the radiator, on top of the trans cooler. How large a trans cooler?

I've been caught waiting on HTG to make DTC tuning more approachable, and in the meantime, unsure if I would hate myself for getting this kit installed and running, and potentially overheating, overtaxing my 7AT at the track.

EDIT: VR30 trans swap is tempting in the meantime, but would be a lot of extra money and effort if I end up being able to DCT swap later this year.

Custom external heat exchanger setup. Not the radiator one, although that is still in use.

Trans Cooler is relatively small. IIRC 2”x5”x12” 10 row with 4 44cfm fans on a thermostat switch, also have a thermostat fluid control valve to mostly bypass the cooler until warm.

There is no real heat exchanger/ warmer like in a lot of cars including newer Q50/Q60. The sliver in the rad does basically nothing. If you monitor trans temps they take forever to warmup in normal driving. My setup has drastically improved trans warm up time.

I wouldn’t hold my breath on DTC swap. I was under the impression it was a lot more work to DTC swap an auto then it is for an MT and the DTC swaps being worked on are for MT cars. But maybe things have changed.

I just got their aluminum driveshaft for the swap, but am likely holding on that build until I put the Roadster away for fall this year. They were great to deal with and very responsive over email. Still waiting on my Vortech Si impeller upgrade and I don’t want to sacrifice any warm weather driving due to build/tune not being complete.

I just want to see more videos of these kits in action…. I’ve only seen the ones from Birdiev (sp) on his YT page… needZ moar’er vid’jas

Well don't have to worry about the auto trans any more. Just traded my 12 touring AT for a 14 sport/ touring 6spd with 35k miles.

Didn't want to get to off topic here so I made a thread in new z owner if anyone wants to see pics and more info on the new z.
