On FACTORY tires, the LT1 Dynoed 609 on a Mustang dyno sliding from side to side with no traction, It smoked the tires. I have the graph Ill post it up soon once I find out how to do it. The setup on the LT1 is a 383 Stroker with a 12 lb blower. The car is insane, it should dyno in the 780 RWHP range now with Drags on a dynojet, and with 20 lbs of boost, were aiming for 850+RWHP

Yes the LT1 is a streetcar, I drive her 45 miles to Mcallen and back sometimes for a cruise, with A/C and Jams.

Well I just thought Id share my experience, the guys at the dyno were freaking out they were like

That was also through a Ford 9" and TH400

 

DAMN....That is STOUT

LT1's are KILLER Force Induction motors

 

You won't do 780rwhp with only 12 psi, prolly looking at like 17-20 psi to hit that thru a T400 with your YS Trim.

I might be dynoing one more time in a couple of weeks and I might have made few changes that will increase my numbers. My sig numbers were with 17psi, thru a 9", 28" slicks, and a T400.

 

nice numbers!

 

The car has dynoed 752 RWhp on 12 PSI, the guys here in SA town say it should break 780 with NO probs as it sits. Wait till I post the graph so you can see what I am talking about. the HP is spiked all the way up to 6400 RPM where they were letting on and off the gas pedal, they were very impressed. The car moved more than 10 inches to the front on the dyno.

 

My brother is building a LT1 383 nitrous motor... what heads are you using?

 

yea i am interested in the combo.

 

Its a 6-speed car right?

 

In one of his posts he stated that it was thru a TH400 auto, didn't say what size stall.

 

Very stout!

 

Those are some good #'s then

 

AFR Heads

 

Ill give all details in the morning. THe car has a Vig 3500 Stall with 355 pro gears.

 

you might wanna keep an eye on that the next time you go!

 

I think you will need 15-18 psi for 780rwhp, what is the pulley combo?

I am using a 8.0 crank and a 2.85 blower pulley. I am also dynoing thru a T400 but also thru a 9" and on 28" slicks. So if we play the dyno game, I could have upped the 746rwhp on slicks to 760rwhp (potentially). That would be 17psi for my current combo. Just a datapoint, because I am maybe going to try for 775rwhp next time but we'll see.

 

Is this the green TA that was at dynotex a little time ago? If not where did you dyno in San Antonio and what car is it?

 

Its a white LT1 Camaro with Torque Thrusters, and We dynoed it at San Antonio Fuel Injection Specialties.

 

If this is a streetcar in SA then i would have definately heard of you. Hell, never even heard of the car.

Do you actually take it to street functions or just dont track it?

not tryign to be a dick, just curious

 

I think he just recently bought the car off another member on the board, correct?
