187whp and 260wtq! I'm stoked. Let me know your thoughts, if there are any.

By all the replies, I guess this is either so incredibly awesome that know one can comprehend a reply, or..................this is the norm. So here are my questions.

1) I got 187 at the wheels for an auto, so that equates to about 230@ the crank. Aren't autos supposed to be around 210hp @ the crank?

2) If stock 5.0's have around 300lbs @ the crank, 20% drivetrain loss would put it at 240@ the wheels, right?

3) Why are my numbers higher than normal, or is this normal?

:shrug: Depends on the Dyno, depends on the tranny, depends on a few things. That's why 'k'no'w' one replies.

I'll just chime in and say yes those are good numbers for your combination. You just don't see dyno results on LB9's so it is hard to compare.

It's also hard to know how excited to be not knowing the correction factor used, or if 0 correction factor was used, what the weather was like. To many variables to get all keyed up over one dyno session. Now if you had another Lb9 car dynoed at the same time and you had more HP/TQ than he did, then you could be stoked...

Those seem pretty good for a stock motor. I'd be happy with them

My first mod besides getting the AC hooked up properly and SFC's, will be a rear end swap. I'm tired of losing races to cars with similar hp/weight ratios because of my crippling 2.73's.

Thanks guys!

5.0L AOD Mustangs dyno those numbers. I thought all TPI motors made 300 RWTQ?

GOY

No, that would be all 87-92 5 liter mustangs....

LB9's made anywhere from 275 to 300 ft lbs, and their big brother's made up to 345 ft lbs (& a mustang crippling 245HP).

At the crank, not the wheels. I can still buy a magazine named "5.0 Mustang & Super Fords". Where can I pick up 5.0/5.7L TPI magazine? You can't, SLP had to start making parts for the 4.6L Mustang because GM killed the Camaro/Firebird.

I only made 355 tq to the wheels

SLP saw no future in the Camaro/Firebird and now builds Mustang parts. Happy with the 355 RWTQ, Kat?

and Thirdgen.org sees no future with you, so i hope you get banned.

Nope. Cause I need to do some more tuning to it still and want a new intake. The stock one is killing me.

so what? judging by your garage you are a real performance junkie! what does that ranger run anyway 18.5 maybe 17.0 on juice? GM has its head up the bunghole BUT the Z-28s and IROCS of the 5.0 mustang era will wipe the floor with any mustang of the same vintage. At the strip, on the street, in terms of sex appeal or in any other distinguishing factor the camaro is light years ahead of the mustang. sorry just simple facts. indeed ford itself was so confident in the mustang it developed the probe, which though still lacking was truthfully a better car than the 5.0 in many ways. just my two cents

i got a 305 tpi stock...i ran a 15.4 in the 1/4 ...but i had a few beers all day, full tank of gas, bout 100 lbs of audio in the back, need tune up , alignment. So im guessin i still have potential to run better....my buddy's stang ran 15.00 with alot of mods https://www.thirdgen.org/techbb2/sho...hreadid=291860 i still gotta use that free dyno coupon

Why are you trolling here? Shouldn't you be on some fourm that deals with bumper hitches and mud? Make sure you check the tie rod ends on that death trap of yours. They like to seperate without warning. Just one more ford safety issue to add to the pile.
