dyno numbers

[hernandez]

to day i dynoed my 94 gt and made 258.64 rwhp and 286.95 rwtq, mods are 306, 70mm CAI, 65mm T-Body, F 303, Edelbroc RPM Heads and Intake, 19lb injectors, BBK Equal Length Headers, 4.10s, 1.7 Roller Rockers. Do the numbers look right or should there been more horsepower and torque

 

[fiveoho]

sounds a little on the low side to me considering your mods....

 

[WhiteDevil]

Yeah with my H/C/I set up i put down 298rwhp and 326rwtq. Were u super lean or something? Your injectors are too small for your combo.

 

[mootang]

deffinatly sounds low for your mods!

 

[hernandez]

i thought so , what do you guys think i should do to get my hp up?

 

[sage2k]

injectors/maf and tune

Numbers might come up a bit with some time on the dyno playing with A/F and timing...but IMO if it drives well and the curve was good/car's fun to drive...I wouldn't touch the valve covers.

It would be helpful to know if you got an auto or stick trans

sounds a little low, what was the air/fuel ratio?

And aslo what kind of transmision do you have, there are a lot or variables.

 

[mootang]

he has a T-56 according to his sig!

 

[hernandez]

it has a t-5 with heavy duty gears, and the t56 is in my other mustang, my air/fuel was around 13.3-13.5

 

[mootang]

what is your base timing? also what kind of dyno was it? mustang dyno maybe?

 

[Killercanary]

Mid 13's is kind of on the lean side for NA engines. All engines are different, but typically from what I've seen an A/F ratio in the high 12's to low 13's will produce the most power on street H/C/I setups. Throw some fuel at it and see what happens.

Very good questions.

I see I was correct in my assumption you were talking about different Stangs

I'm with Paul about a fatter ratio producing more ponies.

The other Q's about dyno type and how you had your spark setup certainly can effect final hp/tq values.

Those 19's are tooooooooooo small

With those 410's ...at WOT ... a heavy load in say 3rd/4th gear with rpm's rising quickly ... you'll have conditions very favorable to produce lean ratios ... even the more so if you still got the little oem pump.

You need more fuel .......... period

At the VERY LEAST ..... work those little 19 with more pressure

just bought some 24lb injectors and a 70mm tbody w/tfs elbow, as for the maf it was a 75mm not 70mm. i hope this will put me up to par
