A 4.15 is only 18% larger than stock and each psi of boost [corrected for temp rise] increases airflow by 6.8%, so 3psi plus 1.0 to drive supercharger and 1.0 lost to intercooler back pressure or 5.0 psi total should be equal give or take.
Unlikely that the stroker can make same HP at same rpm due to losses in heads and valves so you have to fix them.
By 6 psi you are beyond what any stroker can do at same rpm.
Whether the supercharger will out last the extra wear from stroker is always debatable? Sure easier to fix supercharger every few years.

I went with the Brian Crower 4.15 liter kit (11.5 compression ratio), Tomei 280 Cams and a host of other goodies.

I think you are the first stroked NA VQ... I'm looking forward to seeing how it turns out! I'm curious if the rev range will be similar to Adam's or lower.

but no one here is talking about a boosted motor...it's a thread about an NA stroker. We had no desire for a forced induction car....it's been done before, and we wanted something different, as that is what we are all about.

I have a set of 4.08's in my G... I wonder if that would be too much gear for a 4.2L stroker motor?

Should be pretty insane with the increase in torque and horsepower!@

What kind of exhaust are you planning to use? I've been wondering if the Greddy TT Evo would be a good choice... Bigger pipes for a motor with more displacement... might be interesting.
That's interesting... I don't think I've ever heard of Arc exhaust systems before. I like how you guys stray from the normal path and find cool, new stuff.
Any fire coming out of that baby yet?
