First my setup is: drag gen 3 kit, jg edelbrock intake manifold, JE 9:1 pistons, eagle rods, mild porting of head. DSM 450's, walbro high pressure, aeromotive 1:1 FPR..STOCK SLEEVES!!

I will post the dyno sheet as soon as I can find someone to scan. This was on 112 octane

7psi-235.9 hp 181lbft
20psi-390.1hp 306.3 lbft

We could have made over 400hp but we wanted to keep AF's low around 11:6 or so..This was done on a mustang dynamometer..I was way stoked with stock sleeves and such small injectors. Mad props to Modern Garage and my man Courtney. Glad I switched to Hondata as well. Car pulls sooo hard. NOt one sputter. Feels like a factory turbo charged car

 

nice numbers.

are you using vafc to trim fuel from your 450cc's? are you using the vafc 'hack'?

 

Using HOndata stage 3..should have made that more clear in the first post..

 

nice numbers on a dynojet your numbers will be alittle higher.

Ya another local shop has a dynojet. I want to make a pull on theres to see how much higher the # would be..

 

how long did it take to tune your car. they are telling me about 3-4 hours and that would cost me a grip. they were saying that it may take a while becuase bigger injectors take longer to tune

let me know man because i need to tune badly.

IM me when you get a chance

 

my lord!

 

damn i did not know that dsm 450's could have enough juice for 400whp

by the way take off your cat or test pipe what ever you have and have a open dp when you go on the dyno jet i will not be suprised to see you put down 450whp

 

Yeah I will run open down pipe at the track for sure!!

 

great #'s man !

 

how much boost are u running daily with regular pump gas?
good numbers man

 

What was your fuel pressure set at? There is no way that 450cc will support 390whp on stock fuel pressure. I am guessing around 60-70 psi at static.

 

eeep... 20 psi on stock sleeves? non-the-less... good numbers

 

Very good numbers

 

I'm also wondering what your fuel pressure was at with 450cc's?

 

fuel pressure I believe was around 55-65. NOt sure at full boost. I know the duty cycle was around 90% at 20psi..

As for daily driving I am running 10psi making somewhere around 270whp or so..

 

I set the base fuel pressure at 58psi, I knew that the injectors were going to run static sometime so with my calculations found that 55-60 psi with a 1:1 regulator the 450cc's would support about 400hp. I kept upping the boost until it ran out of injector then BAM! 390 hp. On the final datalog, injector duty cycle was 94%.

I used my tuned map from my old setup from last year . I spent about 20 minutes tuning part throttle and the WOT maps were damn close.

Looking for for 12's on street tires full interior.
Good luck Tyler.

THere's the answer from the tuner himself!! You the man Cort..

 

Nice numbers... but try it on a Dynojet next time. I've heard Mustang Dyno's outputting more HP than it really is.

Actually you have it backwards. Karl Martin from RX7.com puts out 550on the mustang dynomometer and 640hp on the dynojet . Both of these dynos ARE local.

You did forget to mention that the Dynojet numbers you quoted are "SAE Corrected" while the Mustang numbers quoted were "Actual" readings. That may not make much difference at sea level, but it amounts to about 20% at 4300 ft in the 'Mountains'. I can post the "actual" Dynojet charts for Karl's "Nasty" if you would like. As I recall, they were around 560 HP (actual).

Fortunately (for you) the two actual horsepower readings are within 2% of each other, which implies that you were able to correctly calibrate your Mustang dyno on that day for that car.

Personally, I would rather tune my car on a dyno that doesn't require human input (read potential cheating) to display my output. That might also be why the Dynojet 248 is endorsed by NASCAR and the Mustang dyno isn't.

Bring in your car, Tyler. If any of our Dynojets actual or corrected readings are within 2% of your equavalent Mustang plots, it's free. If not, you could still share your experience here for others to see. What have you got to loose?

What is your base fuel pressure? I'm running a 50psi base pressure with DSM 450s in my turbo B18C1 and I'm running out of injector(about 90%) at around 17psi and my air fuels are staying about 12.3:1 which means I'm running leaner than you. Really strange, what trim is that charger in the Drag 3 kit? Mine is a .63 T3/T04E.

 

no one?

 

Very Nice man.....This just shows you that tuning is key....Get the fuel right and you can work wonders. CONGRATS!!

Thanks..as far as the trim of the turbo its a .57 trim/.63 a/r..
