that kit would probly make more hp without the supercharger, also its not good because the blower will limit the available rpm range that you can turn... its good in theory but has some practical drawbacks.. it should have 0 lag though! Perhaps if it used a 2.2 kb with it would be better

Tell him he wasted his money. 40 plus psi is not very impressive for hitting 1100 or 1200 HP.

it is actually very effective.  it uses a compunded boost effect.  they are safely making close to 1200 hp on a stcok motor cobra.

Hmmmm. Compound boost to reach over 800rwhp must reach a boost level of 38psi. Twin 57mm Turbo must reach 22or 24 psi. To me thats not very effective.

I think it depends on how you look at it. Raw power, it's not the best, but with constant boost through the entire RPM range, it would be fast as hell. I mean, how much more power do you really need once you get around 1000 HP? Having torque at top and bottom end though would be amazing. I think too many of you just look at the numbers and not what the car could actually do.

turn the turbos up over 16 psi and see what happens.  in the mm&ff  27 psi at the turbos made 1,188 rwhp an 1,015 tq.  no twin turbo set up has made numbers like that that i have seen.  marks single 88mm turbo mad 999.7 rwhp at 33 psi.  and the motor did not last long.

27 psi for turbo plus 17 psi from blower = 44 manifold psi which is the boost pressure

You need to read up on compound boost... thats why they use both.. for less strain on the internals...

Please explain. Turbo's use free hp.. Superchargers use HP.. And what about the fact the compound boosting you need more boost to make the same HP as with just turbo's. It is true that it works, but for the fact that its better than turbo's... I'm not so sure. The higher the boost the more strain on the internals

the compound boost will eventaully cause the blower to spin at a rate that it will become ineffective, kinda like a blow through carb.
