***Topgunz ROTREX C38R Supercharger Kit***

Kordain

Hi Guys

Long time lurker and occasional poster here. Happy to say I completed my TopGun Rotrex SC build (incl waste gate addition) over the winter (Aarons prob even forgot i bought it its taken so long lol) and in June got it on the Dyno with Seb at SpecialityZ (cant say enough good things about Seb n Gregg, awesome professionals & enthusiasts to work with).

Kit was Aarons 93 Oct 500whp setup plus the Tial MVS wastegate, tuned to 511whp, 393 ftlbs torque w 11.6 psi WG spring (Dyno chart below), Dyno day Vid link https://youtu.be/EorNHSTusHc

Very happy with the build. Quality of the Kit was very high. Instructions (pdf) were good (could do with an update) and fitment was good for someone with experience working on cars etc, i,e, its not plug and play but this is working on modifying cars w aftermarket gear, shouldn't expect anything to be

So thanks to everyone thats posted here, i used a lot of your knowledge sharing to select and build from

Now as we all know a build is never totally finished, heres some questions for my next bit of winter work,

- Blowoff Valve
Can anyone tell me what BOV Aaron supplied if ordered early 2023? Cant seem to find the model info.

- Pulley bearing failure
I've had premature belt pulley bearing failure on the SC bracket (anyone else had this?) and don't know what pulley I'm looking for so i can purchase a replacement. Can anyone tell me from the attached photo what info I need to get the correct replacement part please?

- Belt friction point
It looks like the belt is rubbing on something somewhere in the engine and i cant find it, really bugging me and starting to be a concern. There is a quarter inch wear band on the engine side of the belt and some dust getting thrown onto the hood, see photos. Anyone any idea what the contact point may be? Hoping its a known thing and not just my mistake on the install. Its only light friction wear, no heat or smell, but obv needs fixing soon.

That's it. Hope you're all enjoying summer driving, stay safe and thanks

Oh, also happy to answer any questions anyone might have.
