Think im jealous also lol...... but i was dynod on a mustang dyno and have changed intake n exhaust since then

Tell me more about your Mustang dyno numbers before and after your intake and exhaust change. I am just not convinced from the numbers I have seen (this thread aside) that the FAST 102/102 TB is worth the $$$ and if a change from 1-3/4" to a 1-7/8" headers is worth the trouble.

As far as the numbers from this thread, maybe the air in Canada is way different ... much more dense ... more oxygen content .... yea that's it, different air up there makes for 10% increases in power ... lol.

those are some crazy numbers for your specs

anyway, good luck with your setup

like i said before i find the numbers on the high side also, without changing anything on the dyno, what could be the reason for my high numbers, the vette in front of me ls3 2008 made 363. the 69 charger 440 6 pack with lots of work made 480rwhp running lean, and had dynoed the engine alone at 577hp, that seems fair for those cars

BrianSF-GA

You are correct, the numbers for the cars you described that dyno'd before you were "spot on". The only way to really tell are ET's! Just bear in mind that using "drag racing calculators" are for perfect conditions ... perfect traction, perfect suspension, perfect DA, perfect shifting and a perfect power curve (i.e. reasonably linear power). So, just because you plug in an ET and a hp figure in a drag racing calculator, doesn't mean THAT is the ET you can expect, especially the first time out.

i am figuring that my numbers are at least 10% over what they should be. there was also a 2008 vette with 427 headders, no cats, cold air, black widdow cam and tune that made 593rwhp wich i figure is about 10% to much. what do you's think?

Here is link comparing a stock C6 Z06 & I'm going to assumed tuned, then headers. Compare the torque numbers to yours.

You should probably fix that valve float before you break something.

I havent dynod yet but 3 things hav changed intake/exhaust(headrrs back)/sd tune...i say a difference and gain switching from 1¾ to 1⅞ on my 346 and would run nothing less then those on any motor.

BrianSF-GA

What kind of "Mustang" #'s did you put down before the mods intake / header / exhaust mods to your 403? The 4" bore heads, FAST 102 & 1-7/8" are exactly what I would like to ad, but, I have not seen huge hp/torque per dollar increases to justify it.

Currently I am working on dialing in my suspension ... engine mods may not be needed to reach my goals.

Idk what mustang dyno it is tuned at slowhawk. With a untouched 92/92, lpe maf, 3½ single cutout made 519/474

BrianSF-GA

519/474 through the S60?? Those are great #'s on a Mustang dyno vs. a DynoJet dyno!!! You shouldn't be jealous at all by the OP's #'s. Any ET's with the new or old setup?

Its ok i always like seeing the power #'s. But went 11.2 @128 old setup, car weighing in at 3775 me in it shitty 60' needed shocks in the rear so the suspention was squating but then unloading cause it to spin ...gota get this thing tuned on the dyno now then maybe a track day
