"Squirt"? Are we in third grade now?

So then, NO you don't have or work with non intercooled PD blowers. (I forgot to ad the non intercooled part in my previous post.)

As the guy who designed/tested and started making the set up to use the M112 on the V6, I've done years of work. And everyone who whines "It needs an IC" has been proven wrong. IATs post blower do not rise enough to cause heat soak power loss. I've open tracked the car for countless hours. Many of my customers have done the same thing. Same on the street driven set ups I've built and sold. NONE have shown heat soak issues. The only people who cry wolf about heat soak are people who have never run the cars that way. I run three non intercooled Eaton set ups (M90 on a 4.0L SOHC @6 psi, M112 on a pushrod 3.8L/4.2L from 10 to 18 psi and M112 on a 4.6L SOHC @ 6 and 9psi).

Oh, and your roots vs twin screw is worded a bit incorrectly. Both compress air into the case/intake. TS just has more twist in the helix to make it more move more air per turn - on turn making it the more efficient style.

Datalog your car doing WOT pulls on the highway and post the file. Prove it.

LilRoush

Or how about not do WOT pulls on the highway like an idiot.

What will posting a sheet prove? The first thing you'll say is that it's fake.

How about you talk about your time working with non intercooled set ups. Or you post a datalog of a non intercooled PD blower set up to prove your point that they are rumored to suffer power loss from heat soak.

Hangwire

AHAHAHHAHAHAHAHAHAHAH

There are ways of validating the datalog file. You would know that if you had any experience with tuning engines or understanding engine dynamics/parameters. I dont have a freakin non IC setup, you do. Datalog your car and back up your claims. You're living in a dream world.

LilRoush

Thanks for proving my point - by that I mean not being able to prove yours at all.
And there is no way to prove a car is running a non intercooled blower set up based on the datalog. Anything can be faked these days. ANYTHING. I've delt with hundred of know it alls like you.... most telling me that things don't work when they've never tried.

Back to the topic at hand.....

Hangwire

Yeah lets do that hotshot. OP Don't run any more than 6 PSI on an non IC PD setup in my awfully wrong "opinion."

Rockwell28

with his pricerange im thinking he's looking at a centri non ic.

Hangwire

Yep, thats what i'm thinking too. And a non IC Centri is a lot better setup than PD. Go for it OP.

I'm 100% with Hangwire on this one! Let me give you an example: My buddy has a 2001 Cobra with a basic HCI package, and a non intercolled Kenne Bell running around 9 psi. When the weather is cool he can beat me on the juice pretty dang good. On warmer days it's a drivers race. It makes that big of a difference.

Also our local tuner (who's done countless different blower setups) has said on several occasions that any non intercooled positive displacement blower will noticeably suffer on warm summer days. He even states that you will notice it with the centrifugals, but not to the same degree.

LilRoush

On warmer days, NOT after running it longer/harder. ALL cars will loose power on warmer days. That's racing 101.

You guys crack me up.
