I dyno my Stang last saturday at FFW Norwalk OH

Slow5.0 · Jul 13, 2004

I'm kinda pissed because it went lean 13.8:1 in first run (he shut off on 5K), than I bump fuel pressure from 38 to 42 (vaccum hose attached) and it drop to 13.5:1
First pull I got 230.2HP/273.2TQ , sec is with 42psi fuel pressurre 229.4/278.7 I got 5TQ with higher fuel pressure,
I think I need bigger injectors 24s or 30s because I put a lot ait in stock heads but not enough fuel
BTW i have videos on the dyno but I have to put on server

Nice numbers for your mods.

Killercanary · Jul 13, 2004

Nice numbers Ernie! When were you there? I was there with my car on sunday. We went to Cedar Point on saturday. I go every year now. With that dyno graph, I wouldn't be afraid to even try shifting higher that 5500 like I did when I had a similar setup.

Slow5.0 · Jul 13, 2004

I calculate on Zero Signal shift point calculator,I come up with
1st to 2nd 5700 35.0mph
2nd to 3rd 5700 58.2mph
3rd to 4th 5600 85.9mph
4th to 5th 5600 115.5mph

So I have shift like 500 more than peak HP correct or ?

I was in Norwalk in Saturaday , mine friend stay to sunday (Green Bullit with chrome bullit rims,Blue 01 Lightning,red kenne bell 96 Cobra with white racing strips, yellow 01 Mustang GT,red/black 93 Notch with Turbo 331ci

Dude that's almost what my cobra put out. Good #'s there.

mo_dingo · Jul 14, 2004

His calculator is pretty dang accurate. I would trust it.

Those numbers are SAE too; That is damn impressive! What were you expecting BTW?

I mean with {full exhaust, Ported/Polished Cobra intake , CAI, MAF, FPR, Hypertech chip, MSD 6A Ignition & Pulleys} you gained 50hp to the wheels. That is damn impressive.

Nice numbers! if I had a server up, I would host the vids for you.

tmoss · Jul 14, 2004

Ernie - NEVER, NEVER shift into 5th on a 1/4 mile run, just in case you didn't know.......

igotyofire · Jul 14, 2004

what do stock 94-95 cobras dyno at out of quick curiousity

I never shift in 5th tmoss, I think I'm at 4700rpms in 4th on finish line

BTW my brother will upload on his server that videos (two from outside and one from inside)

I get those numbers with all in sign except HYpertech chip , because I fell losing HP/TQ with that damn chip, I called Hypertech and they said I have to have timing on 10* and than chip gonna bumo timing to ?? but same thing so I leave on 14* and w'out chip and guy who have dyno told me that chip is from the shelf so nothing special
Any way now I gonna get some injectors to rich up this lean motor ,than get some heads and cam, but you will find my threads about that so post in them "please"

Joe 5.0 · Jul 14, 2004

I dunno, thats only 10rwhp more than mine and I dont have LT's, didnt have a MAF at the time, and I still have the stock intake.

I dunno, I guess 40rwhp is pretty good for your mods, but I am hoping for closer to 245rwhp after LT's and intake.

Your hp curve doesnt fall off a cliff like mine does though.

Did someone say Mt. Everest?????? You should be shifting at 5000-5200 or so.

Sorry, couldn't resist. Ernie has an extra 500 rpm's on you, which makes a huge difference.

I was very surprised at his torque curve when I saw it.
Scott

tmoss · Jul 15, 2004

@ 5,200 rpm there is ~15ft-lbs difference between the two curves. Not exactly a cliff, but Ernie does have more area under the entire curve.

WhiteDevil · Jul 15, 2004

i dont think you should need bigger injectors. I made 250rwhp with my stock heads and cam, and just used a 255lph fuel pump and a FPR. It made a solid straight line 13.25 A/F ratio, which is a good area for a N/A car. i had about 42psi fuel pressure.

I have 255lph high pressure Walbro fuel in tank pump and Kirban Billet adjustable fuel pressure regulator too and 42 psi fuel pressure BUT I have 80mm MAF from 01 Bullitt Mustang with my stock (94-95 GT) MASS air meter and that meybe why my lean out to 13.5;1
On first run I have fuel pressure at 38psi ,than on 2nd run I bump pressure to 42psi and I get 5 more TQ

Look at my sig i have a Pro-M 80mm and anderson power pipe. But our cars could be different. You never know.

I usually shift the 1-2 @ 5500 rpm, the 2-3 @ 5300 rpm, and the 3-4 @ 5000 rpm. What could account for mine having 10lbft more tq though? I thought that LT's made tons of low end tq, plus he has an intake. Not being a dick, just curious.

Slow5.0 · Jul 15, 2004

No fight guys, we are Stangers
I lose low end TQ BIG TIME when I installed ported Cobra intake , but at high rpms I can heard scream of air from Intake

I dyno my Stang last saturday at FFW Norwalk OH
