Really they vary a bunch ?? Every mustang dyno in the Ohio,Michigan,Wisconsin are all read within about 3% of each other. on the far end of the scale not regarding weather.
car runs low 11's in the 1/4 around 122-124 ? sounds about right if the 60ft is in the 1.8-1.9 range ? proboly goes 11.90 at 118 or so with a 2.2+ 60ft

This 440 number was a nice jump from when we had 412 Mustang rwhp with the old heads/cam setup. That particular setup was worth 475 rwhp on a Dynojet. ![The Judge](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_judge.gif)

page 4 and 5 were locking up on me..
SOrry if this was asked already, but how would dual X dumped work for the exh?
and one more Q.. Would you be possibly marketing a similar flowing set of heads? Possible h/c package w/ those similar or same flow numbers?

Can't wait to see your results.

486/450..
A little low on torque compared to predictions...But my tuner seemed to think it was fine..My rear tires hate me,though.
The data was indication that towards the top of the curve,we were running into an intake restriction..It looks like I need to get the FAST ported.
I descreened my MAF right before the pulls & removed the restrictor plate from the Borla.
Beyond that..I dunno..A compression bump is off the table...those heads aren't ever coming back off...Max power was made with 26 degrees & the AFR was dead on..So whatever I get with a ported FAST is what I get...
Now granted this was an uncorrected # in 85-90 degree heat with very high humidity..So that might have something to with it.
Mod list..
-TSP 383 ,custom Patrick G cam,Fluidampr U/D.
-TSP 5.3 stage II.5 heads @62cc
-Harland Rebuilt OE rockers/921's/LS7 lifters
-QTP's/ORY-Flowmaster Y/3" Borla cat-back
-Strange 12 bolt 3.73's/LPE Driveshaft/Kirban shifter/SPEC 3+/aluminum Flywheel
-FIPK,SLP bellow,SLP 85mm MAF,FAST 90/90 intake & TB, MSD coils
-BMR SFC's/LCA's,Hotchkis STB/Spohn Chrome-moly torque arm

I've analyzed Pat G's combination to see where I leave power on the table...
He's making his numbers with 36 less cubic inches..This is truly extrodinary.
His car is the 1st I've ever heard of to do so..
He's making what an average guy makes with 402- based engine.
The key,besides careful parts matching & his voodoo like ability to spec a camshaft, is in the cylinder head...
Lot's of competent man hours into a great aftermarket casting obviously pay off in a very efficient,powerful engine.
By contrast,I'm using an "off the shelf" OE based head with a limited valve size & CNC port job..The folks who put my heads together are not able to put the kind of time adressing issues like flame quench charictersistics of my particular combination..So as a result,I can't get too carried away with compression & pump gas.As the car is now..I couldn't drive it with anything less than 93 octane without it pinging(Cali-91 wouldn't cut it).So I'm limited to 11.4 to 1...
The second area is on the inlet side..First is my use of a MAF,second is the unported FAST90/90.
The next area of concern is my use of a 2 1/2 Y-pipe.This is due to space constraints under the car..But it is the same exact configuration as Pat G's 3" Y..Just smaller..
I still run a belt driven water pump..I still have OE style valve train...I put it all down through a 3.73 geared 12 bolt...They say higher numerical gear ratios show less RW..I dont know to what extent..& of course,the 12 bolt rear itself affects RWHP readings negativly as well..
So there ya have it.
Cubes are less important than combination.

He has the 4" y with the cutout then back to 3" for the catback. Even with your borla its not going to flow anywhere near his 4" cutout right after the y. Then like you said also he has the afr's if you had those or the trick flows, ported fast, that stuff would really add up.

Since my motor was down around 20 rwhp from where it was, it was going to be really hard to make 500 rwhp with the heads/cam swap so we decided to have Erik Koenig freshen it up. Same pistons, same rods. Erik installed fresh rings and bearings and meticulously reassembled it. Couldn't have done that to a blown up motor.

Pat are you on a 1 3/4 header or a 1 7/8?
once i get the TFSs i was debating on ditching the jet hots(1 3/4) and go to the AR 1 7/8s
im also gonna have my Fast ported.
thanks
