OFI single LT1 dyno numbers I just got back from Akron Horsepower from dyno tuning the mockup LT1 car. The car has my single turbo kit on it with a T-68, 1 3/4 tubular headers, tial 44mm, 3" DP, 2.5" crossover all in stainless steel. The car is a bone stock 93 trans am with a auto trans. I was running 6psi with the air to water kit. The number were 347rwhp and 407rwt at 6psi. Bone stock the car dynoed 250. Im pretty happy with the gain considereing its only 6psi. Will have a graph up soon. I forgot them at the dyno shop. Been busy there this weekend tuning this car. Need some sleep.

I thought so to. Efficiant system is about 10-15 hp for 1 psi. I could of put 8 to it, but its not my car. For a 93 it did really good. Now I have to drive it to Illionis this weekend for the customer. Ryan should love it.

I think 100 rwhp is pretty good for 6psi, considering its an auto that started at 250 rwhp. I think most people are use to the LS1 making 310 to 350rwhp to start and then add the 100 to 120 rwhp to that number, your making in the 450 rwhp range with the same turbo kit. The poor little LT1 just does not get the same numbers stock when you do an upgrade like this

Gotta account for the automatic. My friend made 492RWHP (motor only) 383 LS1/6 through a 6 speed. Put an auto in it and only made 43xrwhp he lost 60hp going to an auto
