So I have 1050hp motors and after the blower eats 150 , I make 900?? I don`t believe that.

Mike, same heads, same boost?? Compressing air creates heat, Whipples still make heat .

I don't see that being unreasonable . Let's spin one of your huge commercial A/C compressors to 5000 and see how many Horsepower that takes.

nothing changed on the engine,just the supercharger.yes when you compress air you create heat just not as much with the screw blower.not the same boost,you can safely make more boost with the whipple.

Whipple sound like a greats Value ? Less heat so not the need for a inter cooler if not desired and over all more efficient . So what is the downside?



CFM to CFM what does a Roots go for compared to a Whipple?

mike tkach

dan,i would say 150 is probibally pretty close.another way to look at it is you have a 750 hp engine that makes 900 with the blower.i will bet you pick up 30 to 50 hp from the compression increase and the ring seal&valve seal.

Cost...by a ton.

mike tkach

the inner cooler lets you run a little more boost.if you keep the boost at a safe level and have the correct tune up you don,t need an inner cooler.dan made 900 without an inner cooler with iron heads.we are upping his compression ratio so if we leave the boost the same he will make more power.i can,t say but i think he will turn the boost down and stay around 900 hp.

Now we are in Iceededppls realm . Lol

tommymonza

Long as we are on this subject , what are you losing for horsepower or intake flow with a inter cooler ?

mike tkach

imo,nothing,you just turn the blower a little faster to make up for the restriction.it really is not much.if you were to add a boost gauge above the inner cooler i am guessing 1 to 2 lbs more than in the manifold.remember,boost,or pressure is created from resistance to flow.
