Dyno appointment wednesday in columbus Predictions??

[tmotorsports]

My 91 mustang GT that ive owned for 16 years and have changed so many times over the years is back together after sitting without drivetrain for last 6 years is back together again.I had the 302 out of my sleeper fairmont put in it with the C4 transmission with brake.I sold the turbo kit and fast system off the fairmont so i ended up buying an on3performance turbo kit and upgraded to the 76mm master power turbo.
So its a mountaineer Gt40P 302 stock
has custom bennet turbo camshaft
typhoon intake
60# injectors
complete aeromotive fuel system with A1000 pump.
Built C4 transmission
3:55 Gear
not sure what boost gonna set at im wanting low boost like 10#
any predictions on numbers?
with Gt45 turbo on this combo in fairmont the car went 10.80 at 126 mph in #3364 car

550 depends on the boost

[mustang8998]

I'd go 500, if the block holds it.

[bkstang95]

What kind of psi are you seeing?

[draggin50]

Im saying in the 550 range as well. I used to have alot of video of the fairmont. Unusual car that was flat ass fast!! Everyone always was right there to watch it! Good luck on the Gt !

Dynotune? If so Brian has a knack for making them run real hard but he will always keep it safe

[Gearhead559]

it will lift the head gaskets

[tmotorsports]

it will lift the head gaskets

it dont have stock head gaskets.has cometic gaskets and ARP head studs.they have been on there for a few years but not stock.I had this motor in my fairmont at the 1st pinks all-out i went to with stock head gaskets and torque to yield headbolts and it was runnin 11teens with seapin head gaskets.

yes dynotune

[tmotorsports]

What kind of psi are you seeing?

probably gonna go 11# right now I went 10.80 126 mph with the GT45 on right at 14-15# of boost on this motor in the fairmont.we never had it dyno tuned we tuned it with a FAST system then

[331TwistedWedge]

10.80 at 126 is right around 410-415 to the wheels on a n/a car - 3100 lbs or so ...

[PaulFiveOh]

So if 415= ~ 10.80

What does hillbilly (footbrake on 10.5in) 505hp =?

[331TwistedWedge]

i know that c4 is going to read low ... the hell with the dyno numbers, let the track tell you how fast you are :bigthumb

yeah ive never really cared about the dyno numbers in the past and dont now just curious to predictions.
this motor in the fairmont was awesome and the only numbers i had were Ets at the tracks.i had it at pauls when I 1st built it and its was mass air with a PMS before i switched to the fast and it would not even load the dyno made like 244hp with 2.4# of boost.

[denial]

I'd say 426

[Buckeye]

480-525

[cobra429boss]

Im gonna say it again 550 .. No problem..

[331TwistedWedge]

so what did you do? ... its wednesday ...

[tmotorsports]

it made 448-518 would only go to 14# of boost the stock GT40p heads are just not enough.brian at the dyno said the way the boost was workin if it had a bad ass set of aluminum heads he could have gotten it to close to 600 horse.and just got a spot for pinks all-out norwalk in 2 weeks so i gotta finish her up

bangingears made 636 with p heads and a masterpower,dump that lil turbo;)

[adragon72]

That's some good numbers! I'm currios as to why the p's are holding you back. I thought the p's were better than the gt 40 heads. I know a good set of alum heads would make a he'll of a difference.

[bangingears]

stock explorer engine- mustang cam
3200 lbs
MP T70 with .68 back half
tremec trans
636 rwhp on 15 psi
500rwhp on 8-9 psi
10.70's@131-133mph on 8-9 psi

Added trick flow heads and F-303 and lost 100-120 rwhp everwhere. Put 50 dyno pulls, second set of trick flows, and re-degreed cam and still didn't find the power. Made over 700rwhp when wastegate seized shut. The "p" heads aren't you problem.

it is a master power 76mm turbo.plus my numbers are gonna be lower because its got a built C4 in it.most cases they always read lower.it feels just as nasty or nastier than my little sleeper fairmont and it went 10.80 126pmh and 11.0s consistently.im not big on the dyno numbers more worried about the ETs

Eventually im gonna build a dedicated 331 for it with all the best.its just funner right now because i have 2 spare shortblock and 2 spare longblocks in may garage that i can run if i need them till i get other stuff around may house thats more important to my family done.

[denial]

i was closest. What do i win?
