200-250 hp dyno sheet needed

[freebyrd24]

Hey, since my fuel pump decided to die ON the dyno, I need a dyno sheet between 200-250 hp for a turbo'd 2.3 or 2.5. I need it for a final report and am now outta time to do it myself since the fuel pump died. any help would be greatly appreciated!!

will this one work?

if you need specs then

2.3l TFI distributor
mildly ported, stock valve size, N/A 1986 head, polished chambers
stock LA2 ECU, VAM, and 35# injectors
18 psi boost @ 10 degrees base timing
paired pulse, 1.25 primary, pipe header
holset HX35 turbocharger 16 cm housing
38mm external paired wastegate
18 feet of 3 inch exhaust
stock 90 lph in tank walbro fuel pump.
24-26 mpg highway and 19 in town.

was nothing fancy, straight meat and potatoes, and still ran out of fuel at 4800 rpm.

this is about as far as you can go without a tuner, chip burner, larger injectors, or a maf conversion on the LA-LB-8UA ECU's. you might be able to tweak another 20-30 hp out the dyno but drivablity and fuel milage will suffer in street driving.

That looks great AJ! Thanks a ton! Those are some pretty impressive numbers with what you described! Great job! And thanks again!!!

I really don't understand the current trend of dyno graphs with hp and tq vs speed instead of rpm....

If AJ's stang would have had more injector his dyno sheet should have been over 280 RWHP. 268RWHP is good for 35lb injectors :D


This here was the 1st time I went on a dyno. 2.3L 18PSI of boost 18* timing at 5000-6000RPM's 42lb injectors 12.5 A/F ratio.

Is that the max for 42lb injectors? If I'm shootin for 300whp should I need more then 42lbs?

The calculation on what a certain size injector will support is.

42x4=168 168x2=336HP

Ahh that's some pretty easy calculating. Perfect. Should be close to or right on the money then.

sorry i was home before i figured out that it was speed instead of rpm. dont know why he printed it out that way.
