I have been searching for the past hour and havent really found much info on this. I know sideways is running highboost supercharged application but has done some engine work.

My question is, What is the safe amount of boost, from a supercharger, that a stock F22 can handle?

Will be tuned via KPro.

 

What octane fuel? I think people are pushing about 11psi on 91 octane.

 

We have 92 Octane here. Im on 12 psi currently and seems to be taking it okay.

 

I would run 1 bar of boost. Thats about PERF IMO

 

More then what the blower can handle

 

The rotrex can handle 1 BAR. Just ask Eternal.

 

You sure about that?

 

eternal had his boosted to 1 bar for how long? a few months b4 i think he either crashed it or crank walk? i forgot

 

Yeps I crank walk a bit after I went 12psi i think i put 1000miles and maybe 10 runs to 100mph+.

1 bar = 14.5 psi?
am at 12psi lol but am shooting for 14psi this spring w/ the same mods goddard did to his blower. Will see how it handles it then.

Juntuned ran 13% overspin way longer than i did.
Someone else forgot his SN has 60k miles but he doesnt push it pass the limit very offen.
So for now I think we can say it will handle 12psi on street runs every now and then.



OP has a SOS s/c so lets keep this on topic.

Not many people run 14psi let alone 12psi on s/c with a stock motor so your not going to get much real info except what people think.... So just do it if you want to test the limits.

However my tuner (Jeff Evans) said 14psi is fine since s/c doesnt make the power a turbo would and he doesnt like to tune a turbo over 12psi on stock compression.
Mase however sells a turbo kit with a tune for 14psi on stock compression.

So with these 2 great tuners doing what they do I feel pretty good about going for 14psi.

 

I ran 12 psi on 91 octane. I think you can safely run that it perhaps 13, and MAYBE 14 but I think that anything past is a bit risky.
