New Rotrex C38R Supercharger

tiller

I wasn’t able to get my car on a dyno last summer, bought another car in August so I didn’t get a chance, but I will try this summer once the snow melts to get it on dyno with both pulleys,85 & 80

Seat of my pants feeling with the 85mm was great, 1st gear is absolutely useless,that’s why iam rethinking gearing, only issue is the crash bar in front of intercooler, I think it hinders our cars a lot, gonna install FI crash bar this summer.

You don’t have a boost gauge ? And I was watching intake temps in 100 degree summer day and intakes were 118 degrees ... not sure if more air will change much .... I do have a water/meth kit sitting in the garage ready to go on and tune ... that should give me a little more

No boost gauge, new car took up my parts fund but I got my parts list ready for this year, my seibon vented hood did help a lot with engine bay temps and intake piping temps, I am thinking that having half the intercooler completely blocked can’t help anything but I could be wrong. I’d install the water meth if I were you cuz then you can add more timing, I was shopping for a system to. Here in Canada where I am we see daily summer highs of only 25celius so I can make big power but then traction becomes an issue, spinning isn’t winning
