LT1 383 Blower Build POST 80....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.

The car will still be street driven. Its going to take a little bit but I have 85% of the parts so we will see how this goes. It looks good Brian! Bob

Get ready for a whole lot of tire shredding. F1's build boost a lot quicker then you'll realize. How much boost are you going for? Make sure your pullies are aligned perfectly because even w/ a 12 rib set, you'll shred that belt fast.

Can't wait to get the motor built. Once a few more parts come in, the rotating assembly is being dropped off for balancing. Then I get to put it together.

I can't wait! Looking for 15lbs to start and go from there. I've read a lot about the importance of having everything aligned perfectly to avoid those issues so hopefully getting it there won't be too bad.

7.5" crank / 4.25 blower pulley. Originally, procharger spec'd a 8.5" crank pulley with a 4.5" blower pulley..... this didn't seem right when I did the math and realized the impeller speed would be a few thousand RPM over the blowers limits LOL.

VERY nice build. I've always loved your car and look forward to seeing the next step.
What kind of boost/power levels are you hoping to achieve? I'm in the process of planning my next build but I can't honestly decide between the 3; LT1+boost, LS1 and boost eventually or sell it and start saving for the 97-99 Viper GTS I dream of...

Looks great! You're using all the right parts.....great choice on the BB snout and EFI Connection 24x LS1 PCM setup! You'll be thankful in the long run for doing it right the first time
