ok im putting a turbonetics 62-1 turbo with intercooler on my 347 stroker it has a e303 cam fully ported intakes gt40p heads and about a 10-1 cp-ratio first off how much boost can i run with out detonation and how much horse can i expect from it?

 

id say 6 but iv never boosted a mustang b4... but the cp-ratio could b a lil lower and it will help alot more ..its nbot that high now but still not ready for 12psi or n e thing ..... not an expert but this is wat i think

 

what kind of gas do you plan to run?

 

im thinking about 98 octane or a little higher?
