How high can I boost a N1200 on 91 octane

91oct is the limiting factor here Evasive, not the motor. The motor is the strong link in our drive train, we are more worried about the rear end and trans. I think 32psi/8xxwhp on E85 from our member Spoolin is our current high mark for a bone stock F2x. Many regularly run 500/600whp/2x psi range set ups with E85 and a little less on pump. The fuel dictates in our case, not the pressure or HP.

We get this question often. Here is an excerpt from our supercharger system FAQ page:
http://scienceofspeed.com/products/e...ercharger/FAQ/
Q: What power can I expect?
A: The factory S2000 engine is rated by Honda at 240 horsepower at the engine.
The stage 1 system on 91 or 93 octane (USA rating) produces up to 100 wheel horsepower (approximately 115 horsepower at the engine for a total of 355 horsepower).
The stage 2 system on 91 or 93 octane (at 9 PSI) produces 140-150 wheel horsepower (approximately 160-172 horsepower at the engine for a total of 400-412 horsepower). Stage 2 systems can produce 200+ wheel horsepower gains (approximately 228+ horsepower at the engine for a total of 468+ horsepower) when used with race fuel or E85 and a higher boost pulley.
Q: Others have made a lot more than 150 horsepower on 91 or 93 octane fuel, can I do this too?
A: The Stage 2 system can produce 140-150 wheel horsepower gains on 91 or 93 octane. Through years of experience of monitoring engine health, this is the maximum power we recommend on this fuel. This is the same recommendation we have regardless if the engine is supercharged or turbocharged, regardless of what brand system you use. Yes, customers have made more power than this on 91 or 93 octane. However, the safety margin of pushing a high compression engine designed for natural aspiration should be considered. By increasing cylinder pressure to achieve more power, the safety margin against factors like fuel quality, varying fuel pressure from fuel system performance, variance in charge temperature, etc. is severely compromised. It should be expected that engine durability may suffer from pushing the engine beyond this recommendation.

Should I buy 2 for when I go get tuned?

***SOS, when you provide quotes/information it would be helpful if you note which blower your referring to ie; 1220 or 1200, since thew two are very different as far as CFM/power and boost amount related to pulley size. This thread is in reference to a 1200, however I know there are a mingle of guys running both 1220/1200 so the information doesn't become accurate without making the appropriate reference.
