well i have 125 shot wet, 3200 stall, pacesetters LT, ported TB, flowmaster exhaust no cats and its been dyno tuned. it was tuned and dynoed on a dyno jet by bryan @ RPM in lewisville. on the other hand you have a bigger stall than i do so that eats alot of you power, for that size stall and being dynoed on a mustang dyno witch puts you under a load i say your realy close to 500. put your setup in a six speed car and it would put down 500 on a dyno jet.

I put down 474rwhp/514rwtq with an '04 !

**2000T/A Guru** · 09-12-2007, 07:00 AM

With a 100 shot i would make 437rwhp, i have headers, exhaust and a lid, if you have a cam and a 100shot on a dynojet and only make 455rwhp you got some issues

My 04 sucks. I'm slow.

**goat455** · 09-14-2007, 08:15 AM

I think some of you are full os sh--. I had my car done at Katech and dynoed at Vector motor sports so I do not believe I have any issues. I just think some of these numbers are a little imbellished on your part. Maybe if I took the numbers that the manufacturers of all the bolt-ons and added them up I would be at 700hp to the wheels but this is not the way it works. I do believe that some cars will dyno more but this would be slight gains not the big numbers some of you post.

**2000T/A Guru** · 09-14-2007, 08:46 AM

Lol, who posted big numbers? My car makes 337rwhp with headers, exhaust a lid and no tune. With a tune like 345-355 id say. Ls1s make those numbers all the time, i have seen stock ls1s make over 300rwhp with over 100000miles on the motor.
