plus from what everyone that has a Allen says is that the guys that make the Allen one really help out if you have questions. Since their kit is for a Tbird its going to fit right. I personaly would still be torn between a Allen kit and a Vortec with a intercooler. Speeds with either setup is still pretty impressive. I'd love to have a 12/13 sec bird at thet track and see everyone wonder how a tbird did that.
Thanks guys. I'm still trying to make up my mind.......PI heads or Blower. I know the blower would be a bolt and go, but the heads would need a MAF and headers to near the power the power that a blowere would give. The question is would my T-45 hold up to a blown 4.6 in a 4000 lb car. It has the 32 spline out put shaft so I THINK it's from a Cobra.
The FRPP blowers are maxing out at 270-280 RWHP on Mustangs. With SVO heads they settle in at 330-340 RWHP. Well from what I've seen anyhow.
They have no intercooler which means you can't run as much spark advance or boost without knocking or just being knock constrained. The Eaton M112 sits under a much more restrictive intake than the AED kit.
Fast forward to EECDOC's '95 T-Bird with stock heads, stock engine and the AED kit (plus lots of mods), he makes 308 RWHP and 390 RWTQ Runs 12's all day (12.69 @ 107.70 mph to be exact).
Overall you'll make more power with a Vortech, but higher in the rpm range when compared to an AED kit. The AED kit is great for making lot's of low rpm power and gobs of mid range with a strong top end as well. It's just not going to make the kinda peak numbers the Vortech cars will. IMHO, the AED kit is better suited for daily driven, heavy cars, such as ours.
Stay away from the Saleen kit and the FRPP kit. Use an AED kit or a new Roush kit if you can get your hands on one. That's if you want a P/D blower.
