LT1 383 Blower Build POST 140....Dyno Results!!!
This will be my official build page for the rebuild of my 97 Trans Am. The engine that was just pulled was a stock shortblock with a a head/cam nitrous setup. It ran well but I figured its time to step it up.

How much boost are you planning to run, and how much power are you hoping for? I am wanting to do either a forged 355/383, with a blower. What made you choose the F1 over the D1?

Thanks Jason! Good luck with your build.
69GTO - looking to run about 15lbs of boost. Should put me in the 650-700+ rwhp range is just my assumption based on similar builds. I chose the F1 just because if I ever wanted to kick things up more, the F1 gives me plenty of room to grow.

Thanks man. I'm pretty excited.
Thanks. I'm actually feeling pretty good now that everything is pretty much apart. I have a lot of new stuff so hopefully everything will come together since I've literally researched the living crap out of this build to have it come together as smoothly as possible. Time will tell.
F1-A is a direct bolt-on from what I understand.

The F1/F1-A isn't a standard kit offered by ATI. It's a "race" kit not even really talked about in their product brochure. I bought my F1-A setup used, but I'd assume most components are from a D-1 kit, with a few differences for the F1 race kit (different pulleys/rib count [mine's a 12 rib], tensioner, etc).

I'm thinking of putting the 4.25 pulley on mine while the motor is out, just so I'd get to 15 psi a bit earlier in the RPM's and have a slightly higher max boost..however, I'm not sure what "slightly" could mean! 18-20 psi probably. Not sure if I want to push it that far, but it would probably net 700+ at the wheels.
Maybe I should just settle for 650 and call it a day.....
No it's not a direct bolt on kit but 99%. You're gonna have to grind the corner of the ds block to get that F1 to fit. Some even have to modify their abs bracket to get it fit as well. Nothing a grinder can't fix in a matter of minutes.
