This project consisted of transforming this 1994 Trans Am daily driver into a winner at the strip. It came to us with blown engine from the Powerdyne it previously had. We built a fully forged 355ci engine to accomidate the 20# of boost, from the new Vortech supercharger the customer(cjmatt) would like to run. The short block consisted of a Callies Dragonslayer crankshaft, Compstar connecting rods, and Diamond Pistons. We finished it off with a LT1 mainfold, unported LT1 cylinder heads, ATI damper and CSI electric water pump.

We dynoed this past Saturday and were very pleased with the results 518/467 at only 10psi. Plans are to upgrade the fuel pump from a single 255lph to the dual in-tank setup, and then put on the smaller pulley.

Wow. On unported heads.......dang. That thing would probably pick up a gargantuan amount of power with ported LT1 castings much less anything else. Looks like you've put together a VERY nice combo.

 

Its also a Mustang dyno! Great Power!

 

What cam is in that thing Eric?

 

>nice numbers... you guys did the install?

 

It was one of Bret's. Off hand I don't remember the specs.

 

Our facility was going to do the install, but could not fit it in. The customer ended up having a friend do it.

 

How much was the whole build?

What compression ratio are you running? I'm guessing you used an aftermarket ECU?

Thanks.

 

9.0:1

 

Dang, maybe I should have done that build instead of mine. I bet the price was about the same. At least I should have more power when I spray though.

Hella nice #'s.

 

Cool thanks, any estimate on the power output for 20 psi?

 

I don't have any predictions yet. I will be sure to post results after the changes are made and we dyno it again.

 

I talked to the customer today.He wants to try it again with the stock heads and see what kind of power numbers we come up with. Eventually he will probably do a set of ported heads, port matched intake, and 58mm throttle body.
