Yes, I searched. If it is here, I didn't find it.

I need a dyno comparison between the standard JRSC pulley on gas (98 or 100 preferred, but 93 okay) and the high boost JRSC pulley. Same fuel requirements. No E85.

If you don't want to post, please consider sending to me via PM or I can give you my email address. This is for confidential discussions with SCCA to consider allowing the high boost pulley in my class. The dyno info will not be released. It will be used by the rules committee at SCCA which is bound by a confidentiality agreement.

It doesn't even need to be an overlay comparison. What I really need is the dyno chart for the high boost pulley (C38 preferred) on gas.

I found this and it seems to match what I have been told verbally.

Don't forget this car also has supporting mods in addition to the C38 kit.

southside iraq · 10-17-2017, 05:00 PM

anyone have any experience with the C38 with RS pully, in term of power gains?

BayBRZ · 10-17-2017, 06:59 PM

Tried searching thread but not yielding results

Those of you on a carb tune on 91 CA gas- how much whp are you pushing?

245 is pretty typical.

Thanks Mike

Paired up with a FlexFuel kit, E85 and a proper flash/tune, would there be a significant change in reliability? I've heard E85 runs cooler, but an increase in power should negate that?

Looking to go this route in near future, will def shoot you a PM when ready

There is always a risk to increasing output. E85 will bump your output a solid 35-40whp, even with no other powertrain changes. For general street use and light spirited use, JRSC + E85 has been proven to be pretty reliable.

You will need a clutch, MAP sensor, injectors and fuel pump to go with the E85.

Looking like in the next few months I could tell you

If this is a straight up comparison of the 110 pulley vs the 100 then I would really like to source a compatible 90mm pulley and lower the redline.

Unfortunately I have a C30 at the moment. Is that a 90mm pulley by chance?

It is! I'd recommend a 6500 RPM redline with it on a C30.
