Topgunz ROTREX C38R Supercharger Kit

Z eliminator · 03-22-2021, 10:02 AM

Question, would the blower fit on a gtm stage 2 kit

TopgunZ · 03-22-2021, 10:06 AM

It would fit, but that system is not designed for the C38R. The pulley system is undersized (belt slip) and the intercooler is WAY undersized. However, it would still most likely make more power than the C38-92.

Now Iv just got to convince my wife why I need to spend more money on the car

Dyno is happening Wednesday at 4pm central. We only have enough time for tuning E85 so we wont have 93 numbers until later. We cant road tune due to outside temperatures. The extreme summer performance tires just cant handle the power when they harden up at 40*F.

The excitement is real!

Was just plotting my MAP vs MAF (sd) data and it looks like if you spin it all the way, should be making close to 20psi of boost, maybe conservatively 16-17 at worst case? So 700whp easily in the scope.

All educated guessing of course. Can't wait until Wednesday!

We all know you have some secret squirrel under the hood that chirps when you aren’t in boost. Time to stick a silencer on your squirrel and turn up the wick a bit. :-)

Will be ordering this as soon as it’s available! Can I fire a deposit and reserve a spot? Haha

Tell her the alternator superchargers the battery so it won’t die within the next 15 years. All sports cars have it now. It’s organic

tonythetiger · 03-30-2021, 11:11 PM

i got to get me this kit lol

TopgunZ · 03-31-2021, 07:18 PM

We have good news and bad news. The bad news is we weren't able to finish the tune because our deskey dongle literally just quit communicating with the software. It just started saying unable to connect. Eugene is shipping a new one 2 day air so we will be back on the dyno Monday evening.

The good news is the preliminary numbers are exceeding our expectations. This kit is straight bad ***!!! We are going to be deep into the built motor arena if you want to send it!

When will the kit be on the site for preorder?

I'll still place them on my site tomorrow since now I know this thing is going to way outperform anything else out there. I just won't have an actual dyno on the listing.
