I haven't done any power mods in 5 years but finally getting around to sharing some average results ... I hope to get some larger injectors and pump and try out e85 since there are several pumps around. I wish I could go flex fuel without much hassle...

Current mods in case my sig changes in the future:
MHI XonaRotor BB FP Red, Recirculated o2 and cat eliminator DP, Tanabe Touring Medalion Catback, 4" IC, walbro 255, FIC 1120cc, GSC S1 cams, JDCustoms COP, ETS IC pipes, FP silicone intake and a cone filter.

Back in 2016 I did compression and leakdown tests with less than stellar results. I haven't done one since but I'm sure it hasn't gotten any better.
Comp - Leak down
1. 147 psi - 24%
2. 150 psi - 14%
3. 150 psi - 11%
4. 130 psi - 28% -155 psi w/ tsp of oil


Should I richen it up in the 4-5.5k rpm range? Or sooner?

For cushion, I would aim for 11.0 from 3500 to 4500 and taper to 11.5

An mhi red on 93 pump gas should make around 430whp or so safely.

I would shoot for 12-12.5 until 15psi, then 11.2 after that. These engines are old and make alot of heat.


E85 target should be 11.5 or so. On E85 you can make 500+whp.

Thanks for the feedback guys. I'll work on the fuel a bit when I can and see how it does.
