power estimates with basic bolt ons

plain92pony · Sep 8, 2009

hello i just finished my car prolly not gonna do anything with it for a while and was just wondering what kind of power im gonna be looking at and 1/4 mile times... here is a list of what ive done to it.

Trick flow street burner upper and lower intake
70mm accuefab throttle body and spacer
24lb injectors and 70mm maf
Ford racing e303 cam
a/c and smog delete kits
jba shortys and full bassani exaust
steeda underdrive pullys
steeda cold air intake
steeda short throw shifter
ford racing 4.10's

i know its not the craziest mustang out there but its my daily driver and im only 19 so its plenty fast for now... thanks for helping

I would say 265 at the wheels maybe.

LarsD · Sep 8, 2009

Maybe 250-260, you'd be a lot better off with some different heads, like GT40P's.

Darkwriter77 · Sep 9, 2009

You pretty much need to take off the heads to poke in the cam, anyhow, so why not throw different heads on while you're at it? At least some ported E7's, if nothing else?

is the stock or explorer gt40 intake diameter 65 or 70mm?

Sounds about right and 265 is enough for low 13's, maybe even high 12's in a Fox. With all the mods that you've done, the stock heads have become the biggest bottleneck so think about replacing those next.

i think 260 without heads is little high? unless you are talking crank....i think i have that at the wheels....

I think you guys are overestimating here.

I'd say 250 crank, maybe 210ish at the wheels.

It still has stock heads. The 24's are unneccessary and without a tune i bet they are helping or hurting. He really needs a cam and heads to get over the 250HP mark crank.

yeah 260 is really high for what he has. when i had every bolt on listed in my sig minus the ported heads and cam, i put down 225rwhp. i doubt he's anywhere over 230rwhp and mid 13's.

7upstang91 · Sep 9, 2009

240-250. Do you guys think the cam with stock heads is hurting more than helping?

aar0s · Sep 9, 2009

im going to guess in the 250 range. I made 224 with an intake, 65mm tb, headers o/r h and dumps.
How do you like the bassinis?

1987GT (5spd/Speed Density)
Ford Racing AC delete (removed AC), Mac underdrive pullies, 140 Power Master Alt, Jacobs ignition, Mac 70mm TB/EGR, K&N filter, Flex-a-lite electric fan, Kirban FPR, also on car 2 1/4" Dyno-Max cat back (rest of exhaust stock).
Dyno numbers from 6-12-2004. I made 225.37HP and 298.63TQ for peak rear wheel numbers and 260+TQ from 2000-4500rpms. Dyno was done on a Dyno Jet 224 chassis dyno.

I'm not saying he is up around 260rwhp but I didn't even have any "major" bolt-ons and put down 225 rwhp. Maybe it makes a difference between MD and DJ dyno.

I won't worry too much about peak hp with those basic bolt-on. Just that your car will still be fun and a blast to drive on the street and at the track. Taking weight off and better tires will help all around.

Cam is probably not doing a whole bunch, leaving you in the 230-240 rwhp area. Should be good for low 13s maybe 12s with a tire and some driving.
