Cam Only T-rex I got a t-rex in a a stock shortblock with 241 heads. The car is not completely tuned yet but so far it has made 335 corrected on dyno. It has all the goodies (fast 90, longtubes, etc ....). But is a th350 with a huge stall that flashes at about 4800. I know dyno numbers dont mean anything but does this seem low ? BTW this exact dyno on my a4 01 z daily driver with full bolt ons put down 298, so we have some correlation how numbers are on this mustang dyno. Im thinking after its tuned we'll have 340hp. IF it matters there were slicks on the rear.

its got a stock 10 bolt. soon to be a 12 bolt. I was hoping some of the guys with high stalled th350/400's could chime in. Im not thinking anythings wrong i kinda want to see where everyone else is with my tranny setup to compare to.

Isn't a fast 90 on stock 241 heads just wrong? I wonder if you would make better numbers with an LS6 intake manifold.

I dynoed 337 on a Mustang Dyno through an unlocked 4800 stall, 4.30 gear, and T-Rex cam. Pretty much the same setup as you. I redynoed it on a dynojet and made 380 unlocked and 423 locked.

Alright that just made me feel alot better about the numbers lol. Do you have any idea how much timing they have one your tune ? My car isnt fully tunned and made 335. A slick came apart on the dyno not a pretty site. I guess that what i get for buying used tires.

My car with a th400, vig 4000, LS6 intake, hooker LT's, ORY and stock 98 heads made 309/304 on a dynojet. I was going to install a t-rex with that and I was looking for at making atleast 360 to the wheels. The slicks are going to take away from you dyno numbers.

Looks about right to me. Take it to the track and you won't care what the dyno numbers were! It'd be easy to get some $$ races by waving the dyno sheet at the uninformed though...
