I was wondering about that number, but I'm still on an LS1 intake manifold and i think that's really holding back the flow on the intake side of the engine. I'm gonna get an LS6 intake soon so hopefully that will go up a bit. I lost a lil compression when i changed the pistons. Got a 2cc valve relief and never milled the heads. The car still needs some tweaking but it will get there soon.

 

I've heard of huge numbers from the TReX and I just haven't seen them from my car yet. I'm really hoping a new manifold from the LS1 that's on there will open things up. If that after that my winter project might be to tear the heads back off and have them milled a bit to make up for the valve reliefs in the pistons that i have now. I think once I do that I should see the numbers everyone expects.

 

I've also got a 26" tire with the 4.10 and if i go up to a 28" tire i think i'll stay in the power band a lil longer and not go through the gears as quick. Gotta get a rear end first. Don't wanna break my daily driver again.

 

Well I have a MUCH smaller cam and 4.10s and my numbers were 445/398 before the true-duals. I know I have the LS6 intake, but still, something's not right here......

 

I'm gonna get a new intake once i get the cash. Will keep you posted on gains and see how it goes from there. I know the LS1 intake is choking my whole setup.

 

u should destroy anything with a damn T-REX...lol. good kill, on the other hand, i think an all black mach 1 is pretty sick.. the 05 GT blows..

 

Maybe he thought HIS engine had the cam in it since it was so easily heard in his car.

 

LOL

 

 

so i take that you have a stock rear end?

 

not true the ford 32 valve mach 1 motor was not touched by the hand of GOD!

 

 

Between the mach 1 and the 03-04 cobra those are the only 2 stangs i would even consider buying the gts are a joke . But the cobras and the mach1s are no joke This is coming from a die hard chevy fan

Good Kill

 

Good kill OP!
But I do agree, something is not right...You should be around 400rwhp with only the T-rex. I'm thinking you should at least be 430+, and then around 450 with the ls6 intake.
But everything could be fine and whatever dyno you used plus those 4.10's might have altered the results a little, I don't know, sounds like she is running good either way!

 

btw i like mach1's pretty well

 

you should be making more power......who tuned your car?

 

To the original poster- Good kill! Whenever I race my friends formula, the race is always much closer from a dig. Unless traction is an issue, that would be the mach's strength. But anybody that doesn't know a radical cam when they hear one probably doesn't know jack$hit about racing anyway. It's not that the results would have been any different anyway.

What kind of times are running with that setup?

 

 

 

are tT-rex specs close to an f14 specs and performance?
