I know basically nothing about the JRE packages - what blower are these using? As PSI isn't necessarily as relevant as over whp (especially if not comparing like-for-like on blowers - ie not comparing PD vs Centri)
However from a whp-standpoint, I agree that I should be pretty similar.
Car will be doing 1-2 events for 1/2 and 1/4 miles but primarily will be used for lapping/track days on road courses - likely will see 4-8 of those per year, maybe some nights in Mexico too.
I agree with this to a point. On the street I'll probably run a mix of 92 and e85... for track days I'll probably run pure e85.
I plan to have it tuned on pure E85 but instruct my tuner to keep timing conservative as the car probably won't the temps on a dyno that it will on track, and this way I can do less to diminish the cooling properties of E85. I'd think track temps will get MUCH higher as the car will be basically full tilt for 20-30 mins, as opposed to just 3-4 dyno pulls. I also don't plan to go much higher than 9psi for the same heat-related reasons.
I originally spec'd the built for the car to have low DCR, low-ish temps (for a PD Blower), and be very responsive/punchy at any RPM. However I was thinking I'd see 600-625whp... And then I saw a recent-ish thread that had the same setup I have but with stock exhaust and no cam, and it made 640/640. So I immediately knew my car would surpass my expectations (and that's also why I bought drop-in pistons), and now it's just managing heat. So even if we go super-low on timing it should still make mid-high 600s, which is just fine with me
I am curious how cool it'll stay with those 3 big ass HXs tho.
This basically solidifies my decision to not buy any more fueling parts til it's dyno'd/tuned. If there's not a need to spend another $1k+ I won't do it.
