Guest Fast Frog Posted September 12, 2000 Share Posted September 12, 2000 I read your reply on pg 2 of that tempestuous post "71 240 w/stroked 383 LT1 and Procharger D1". You made mention, in the 2nd paragraph, that the "P" series ATI is smaller than the "D" series ATI. My ? to you is, would the"P" series fit decently in the bay of of a Z car ( a Z car with a sbc) with minimum fabricaton?? I realize that you may not know the answer cause it may take actual experience trying to fit one. I'm interested in this cause I want to scrap my Paxton someday soon and go with a more efficient SC with a modest boost of 7-8 lbs. giving me about 500HP+/- with my 383. John Scott and I have talked about this several wks ago; but he's got much more room in his bay cause he's running a 4.3 V6. I have talked to the ATI people a couple of yrs ago and from what I remember, the tech recommended a 12 lb Camaro "P" series setup cause it has the upgraded impeller. We also figured that the boost would drop to about 8 lbs on a 383 which is where I want it. If any anybody else has thots or experience on this, please join in. But NO PILING ON!! I an older guy and I'd hate to have to tighten my belt and kick some butt-I might get hurt!! Quote Link to comment Share on other sites More sharing options...
Mikelly Posted September 13, 2000 Share Posted September 13, 2000 I know BLKMGK personally, and he has been in my home. A little back ground on him.. Jim is a techno-freake, and I mean that in a good way. He knows a lot about turbos and superchargers, as his mustang had dual turbos in it and now has a 351 windsor with a supercharger... I'm sure he has a pretty good Idea about the fitment issues, so you should feel pretty comfortable taking his advice when it comes to forced induction...Years ago (about 6) I was hearing about this guy in my professional circle who had an awesome twin turbo 5.0 stang... It was Jim... Mike ------------------ "I will not be a spectator in the sport of life!" mjk Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted September 13, 2000 Share Posted September 13, 2000 Freake? Moi'? LOL! Thanks for the vote Mike - I think Hey, if I'm not sure about something I'll say so and if I don't know something I'll also say so. Quite frankly there's lot's I just plain do NOT know - especially about Zs and lot's I want to learn aboput programming fuel injection (grumble). I've seen both the D series and the P series blowers. I've got a P1200 on my Mustang now bolted to a 351W. Now, would it fit a 240? I THINK the P series would fit a 240 at least as well as a Paxton does. If it would help I can shoot a pick of it and send it to you. For that matter I might also be able to shoot a pick of a D1 blower as that's what was just put on my friend's Cobra and he's got it torn down right now. However on the Cobra it mounts bassackwards so it could be built slight different but I assume it's not. Here's what I do know - the shop I deal with has built blown 351W Mustangs more than once - including my car. The 351W is slightly wider and taller than a Ford 302. As such it moves both heads outwards and up - duh. A P series blower mounts pretty much okay in this situation - it's flexible inlet tube is slightly squished due to PS and frame clearance issues. However, IF you try a D series blower it APPEARS to stick further out to the side and required cutting of the fenderwell for head unit clearance - it was a bit ugly! It's possible that the D series mount was different. The D series blower seems to have a bigger ttransmission in it - more bulky. Reading their specs this would appear to be true - it's got a different ratio to it - higher step up so you can run larger pulleys for more (belt) traction. Looking at the blower dead on the D series appears to mount tilted out to the side more so than the P series. It might be possible to tuck it in closer but I'm not sure. Of the two the D series is supposed to be the better built blower. However on my Mustang I figured the P1200 with a billet impeller would work just fine - I didn't need a Cadillac and the bearings are brand new. Whew, does that help? If I can get pics and it'll help I will - the P series is easy as it's on my car now Look at ATI's WEB site and you might be able to see a difference too. http://www.procharger.com Oh and the "new" P1-SC blowers appear to have the D series configuration, NOT like my P series. Confusing! The models page shows the inlet side of the blowers so that's no help and I don't even see the P1200 listed anymore. Might be a special order or go with a P600 (shrug). FWIW - I'm looking at my Z wondering about a custom ATI install too. One of those big NPR intercoolers in the nose, an ATI head unit, and some form of injection. Can you say drivetrain breakage?
