Curious since that's my dyno in the post.

With different gearing you will be at a different RPM for a fixed roadspeed - so in that sense, yes it does make a difference (for example, the acceleration seen will vary between a 6MT and 5AT even if the car generates the same rwtq vs RPM).
For wheel and tyre size and weight yes, different wheels will have a different mass, diamater and hence different moment of inertia (MI). The (rotational) acceleration seen by the wheel (and hence which translates into straightline acceleration on the road) depends on the rwtq and also MI, according to the equation
rwtq = MI x rotational wheel accn
where MI - function(wheel and tyre mass, wheel diameter)
Translating that rotational wheel accn into straightline also depends of course on traction (so friction, stiction, slip etc come into play)
Thta's my take on it anway

Terry,
Did they tell you that your clutch was slipping up top? That's what I was told and I had the same 'blip' in my graph like you have.
Didn't you just get a new tranny? What about the clutch, is it new too?
TIA

Yep....I have a brand new tranny and clutch.
No slippage that I know of.....CPR said the stock clutch is good for about 450 Hp....normal street use, unless you are tracking the car a lot.

I am not sure if you could run the stock hood with a JT trim but it would deff be an awesome setup to see with a built motor.

I,m laying the ground work to install a 172 cubic inch procharger on my FX-35
it would make 8 pounds of boost on a 5.7 liter small block chevy. and 24 pounds of boost on a 3.5 liter VQ. Buying stock pullies, the setup will get 10.3 pounds of boost at a minimum. (46% overdrive)

I got mixed up. The one I was thinking of is the V2 SQ E-trim..capable of 750 HP. It is a little smaller than the T-trim (up to 825 hp) although they both flow the same CFM (1200). The larger blower capable of up to 1000 hp is the V7 JT-trim. I believe that is the largest counter-clockwise rotation blower that vortech offers.
