car's setup
2.0L sleeve'd ITR block, eagle rods, around 11.5:1 looking srp pistons (dont know for sure on piston CR)
ITR head, stock port, stock intake mani, stock throttle body.
Password JDM carbon 'whale' intake
370 precision injectors
Skunk2 stage 2 cams, full sk2 valvetrain
Profab 4-2-1 Big tube header(2.5" outlet and test pipe)
i think a apexi ws2 exhaust, (dont remember)

peak hp was 214, tq was136

at peak power 8600 rpm,
AFR is 13.2:1
injector duty cycle is 76% at 55psi with walbro 255hp pump

This is on a mustang dyno, if you google mustang dyno vs dynojet, and read threads from all type of forums (mustang, ls1tech, and others)
you'll see a mustang reads approx 15% lower,
thus if you add 15%
this car has approx 246hp, and 155 TQ Tuned by me on crome Pro

SORRY ABOUT THE YELLOW TEXT..peak hp was 214, tq was136




the mustang dyno exported to a TXT file, so i pasted into excel and made the graph above from that data.

the dyno operator had a program on the dyno that populated all the car spec fields, wieght, etc.. and it had 92 civic, 1.5 (which this car was a dx) and i think the weight was 2360 or so if i remember correctly? so the numbers arent 'enhanced' or anything.

 

all of this power tru a 60mm exhaust?

thums up to you dude nice job!

 

I am sorry but I just don't see you making anyway near 246WHP on that setup. You need to go to a dynojet and get some real numbers instead of some inferred figures.

 

big numbers 4 such a mild built......
take it to the track mph don t lie

 

*waves bullshit flag*

 

Yeah, I don't see that setup being anywhere close. Never add %, just take it to a dynojet and see for yourself.

 

the car was "tested" on a aem previously, just a 30 minute base tune, on a different dyno
a dyno dynamics, and it did 220hp there, so 214 on a mustang after a day of tuning doesnt sound far fetched. does it?

214hp and 136tq on a mustang dyno, figure up the 'correct' numbers however you wish.
it's usually about 15%

i doubt the car will ever get tracked, its a every day car for the guy.

the torque in 5th gear on the highway feel's crazy.

darrin.

 

I agree.. Take to a Dynojet and get a real print out from the screen. Those are some huge numbers.

 

Either way.. forget about numbers, I'm sure the car is a blast to drive. But real numbers would be nice.

 

there's no way that setup would make 246whp

 

i concur

 

I am running 370 injectors right now. What is the duty cycle on the injectors at that horsepower level?
I am at 70% duty cycle with stock fuel pressure and am at 200/140 on a dynojet.
I would think those injectors should nearly be maxed out.

 

I would go and get it tuned on a dynojet and come back saying in your face if I were you,just kidding.

but yeah I too think the number you came up with (15% difference) is a little overkill,I had figured that it was more so 6-8% by looking at others experiences,atleast with hondas.I think that would put you at around 230whp which is also great dude so why sweat,

good job,enjoy! stop the hp guessing games and kick some VW,V8 *** already:9

 

I was saying the same thing! I use RC 550cc injectors and make 249whp at 68% duty cycle.

 

i'll chech the duty cycle when i get home. Fuel Pressure was at 55psi and using a walbro 255hp pump.

intake temps were between 102 and 130 the whole day

 

at peak power 8600 rpm,
AFR is 13.2:1
injector duty cycle is 76% at 55psi with walbro 255hp pump

we were in the high 80%s till i noticed someone cranked the FPR DOWN to below stock levels

so i was able to turn it up and lower the duty cycle back down
