Tim, Trying to keep your other post to what you wanted. I not sure if I would be in for a 4 or 5k blower but I think I have a decent question.

If we are going to spend $ on a blower setup that is completely different than what the truck was made for and what is currently on the market, ? is what can we get out of it?

Running 14 psi and getting more horse power than a KB at the same is great but what could it handle.

What does a KB or Works handle 28 psi, 30 psi, 40 psi? I think someone looking for that setup is serious about their setup and is looking to push the limits.

How does it compare in performance at the track vs a roots or twin screw?
Same question as a daily driver?

Thanks

 

A question to some of the guys who know more about this:

I read in MM&FF magazine that ATI is doing a setup for the 03/04 Cobra that USES the stock intercooler. It basically has a sheet metal plenum that ducts air into the stock intercooler where the stock blower would normally sit. It mounts the Procharger at the front of the motor and the setup looks very simple and clean.

I was wondering if this would work too for the L, or if this kit HAS to use an auxiallary cooler.

 

Not sure if I understand all of the questions, but . . .

What could what handle? If your engine will perform reliably on 14 pounds of Eaton boost, it will perform even more reliably on 14 pounds of centrifugal boost. In fact, because of the cooler charge air temps, you could run even more boost for any given timing/air-fuel/octane.

A twin screw is not going to be pushing 40 PSIG on our trucks. AFAIK, no one makes one big enough. But a centrifugal could be spun to those boost levels. But -- wow -- that would take one really built engine anyway.

Not knocking twin screws -- to the contrary, I think that they are an excellent alternative to the centrifugal. Probably too close to call in many applications.

A twin screw might actually provide a more subjectively satisfying driving experience in everyday use. On the track -- be it a drag strip or road course, the engine is always up in the power band. But in traffic, the immediate low-end power of the twin screw might well make for a more "fun" driving experience. Potential advantage to a twin screw there.

But on the track, most experts agree that an equivalent centrifugal will nmake more power -- a centrifugal is more thermally efficient and takes less drive horsepower. But is it still pretty close.

I guess than my point is that any properly sized twin screw or centrifugal is fundamentally better than a roots. You pick it.

And a big THANKS for making a separate post!

 

Thanks, I think I got my answer out of that

 

The ATI 03 Cobra setup has been done since last Fall. The base system uses the stock Ford intercooler. The super high output system (about 650 rwHP, not sure if that one is 100% complete yet) uses both the stock intercooler and an ATI air-to-air intercooler.

A Gen2 setup would be no different. The base F150 kit would be adapted to blow through a sheet metal intake and the stock intercooler. You could also run an ATI air-to-air along with it.
