Upgraded T-78


Jason

raceport

Holy shit! Nice numbers!

:)

Thats pretty nice, what were the ambient temps like at the dyno? How much spark lead at 19 psi on the race gas... I know , questions questions questions.... Well done .....Max

Not sure the temp, but it was not hot.
Timing was 12 advance up to peak torque.

Jason

Nice numbers.. Im confused though. There is a 3rd gen on the cover of "Modified Magazine" with a t-78 from detroit that put down 586 at 19 psi no nitrous. with only a steetport. Do numbers vary that much from car to car that much? Maybe it was colder here? running more agressive timing? but would that add up too 80 HP on the same car?

Bull$hit, not going to happen with a T78 at that boost, probably wouldn't happen with a T88 at that level.
Nice numbers Jason, as for "raceport" I take it, that's a large pineapple street port? :)

Nice numbers man!!!!

Jason have you dynoed on a Dynojet just to get an idea if there is much difference between yours and a dynojet?

STEPHEN

Thanks :D
Our Mustang dyno is calibrated for Dynojet numbers. We took 3 cars that had dynojet numbers and calibrated off that.

Jason

You can call bull$hit all you want. I really dont think a magazine is gonna lie though. Granted, they didnt have a dyno sheet to prove it.. i dont think. I Thought it was pretty unbelieveable too. check it out if you dont believe me, This months Isssue. Its the cover car.

We all know, that magazines and everything you read are always true! :p:
I believe it even more since there was no sheet to back it up.

Good job Jason.:bigthumb:
Who did the tuning?

Thanks!
I did the tuning

Jason

so when are you gonna run it? Race season is almost over....... Atleast show us the mph

Maybe it is estimated flywheel hp. 15% on 506 is pretty close to 586. Magazines really like the bigger #'s.

Nice job Jason :) :D

maybe 586 flywheel horsepower. That sounds about right.
Jason did you make any pulls on pump gas?
So can you feel a noticible difference to your upgraded wheel? Spool time ect..

I ran 16lbs on pump gas and made 458 HP.
The turbo really likes 17+lbs of boost. Spools great. I was going to run 20lbs but was happy with what it got.

Jason

Congrats Jason !!! Nice numbers....
 

Now head to the track and rip some 10 sec passes;)

Funny.......reading this post and also reading that Modofied Mag article on that 586whp FD @19psi !!!!
It's funny how I spot 'bullshit" so fast...........

586whp @ 19psi, w/ durable 20B rotor housings, assembled w/ ARP studs, Mazda Cosmo fuel pump, a set of larger R1 rotors and superior calipers .........
and finally it runs a 12.8 @ 122mph @ only 9psi....
Oh boy, and it also makes over 420whp @ 9psi to run 122mph !!!!!!
Owner is only fooling himself !!!!!

stock ignition?

Which plugs?

Twin Power with Heat range 10 plugs

Great #'s Jason, I PM'd you :)

Funny... I saw that mag in the store today and thought to myself.... What the fuck? Oh well... If he did make that at 19psi... Jason, you need to talk to that guy LOL ... j/k
