Message for "jordan not mike"
Hey had a quick question. Do you remember where you got your ATI procharger? I was wondering how it was working and if you could give me an idea how much a used one would cost and if I could trust them. Also, how many horses did it add and how is the torque? Thanks.

Hi, I bought it about 6 months ago. I read the classifieds but found nothing, then used the search function. The search turned up an ad that a guy posted months before, and he got no replies.
When I e-mailed him, he seemed to be in a real bind. He wanted to sell it, but got no offers or replies or anything. He initially was asking $2800, I believe, but I got it for $2200 or so shipped, I recall, with little haggling.
I went about it a bit blindly, but it's working great! If I did it over again, I'd cover my **** a bit... I would pay the guy to have the head unit shipped to ATI for testing, I think they charge $70 for this service. This would ensure that the blower is working correctly.
I'm not 100% certain what my final numbers are, because I had clogged cats when I was on the dyno. But I made a little over 280hp, and over 360lb-ft of torque at 2700 rpm, with a nice plateau that hold this number to about 3400 rpm before gradually falling as HP rises.
I've since replaced my entire exhaust system. From what I understand, I think my torque numbers are good, but I believe my hp should be a bit higher now.
Man, if you are on somewhat of a budget, this is the way to go

That's at the rear wheels, before your power goes thru the tranny/driveline, etc. There's an approximate 20% driveline loss. Unless you have a power-adder of some sort, there's no way you are getting that to the ground.
My 97 is rated at 235 at the crank, which is closer to 180 or so at the rear wheels, though I never had it on a dyno so I can't be 100% sure.
The guys with newer trucks, with the PI heads like you, those trucks are rated at 260hp, they put down about 190 -200 or so the the rear wheels. Lots of guys on thios site have dyno'd their trucks, that's about where most are at, give or take a few hp.
The newer trucks like yours with ATI blowers and fuel mods, some guys are dyno-ing at around 360 - 380hp to the rear wheels with a good tune.
Torque to the rear wheels likewise is a lot less at the rear wheels than at the crank.

Since I have crappy non-PI heads, I'm limited to less power than newer trucks. But my exhaust is now all-new, no more clogged cats, so I'm hoping I'm running closer to 300hp, but until I get it back to a dyno I can't be sure.
