3 runs with the last being the best. 316hp and 336 tq. she stays over 310 hp from 4800rpms through 6500 rpms but was still making 300hp at 7000k. tq maxed out at 4300rpms but stayed over 300 from 3000rpms to almost 5500rpms. i had my heavy ass 10inch DD chrome FR500's on so with the stockers she had a couple more in her. wut do u guys think?

Good numbers.

your honestly not going to make a different number by changing wheels. plus or minus 10hp can be by different dyno, different climate, different elevation etc. And the benefit of the 10" wide wheel and tire out weighs having 2 more hp on the dyno.

thanx i was hoping for a little more but who doesnt rite lol. with a drive shaft and my stock rims back on is should be well over 320hp

Those are pretty damn good #s just for:

BRENSPEED 93 TUNE
JLT 2
OBX LONG TUBES
PYPES MID MUFFLER

ditto on the 'got my car dynoed today':
best effort was 307rwhp, 328trq with my Brenspeed 87 tune (they didadd another degree or two of timing to theBrenspeed 87just before this run)

Conditions:
cool (69F)
not humid (29.56in-hg, 34 percent)
and about 250' ASL where the Dynojet was located.

relevant power factors include:
GT 4.6L 5-speed manual
Brenspeed 87 'torque' tune
Steeda CAI w/high flow elbow
Steeda UDPs
Summit COPs
Spydershaft 1-piece aluminum DS

My goal for these mods was to eclipse 300rwhp and my setupdid that so I am happy. Even with some error correction this output is very respectable. Next step looks like a full exahaust.

If I keep the above the same but addLTH, Hi-flo Cats, a nice axelback and a custom dyno tune I would expect in the 330+/- range.

Next stop 330+.....

nice numbers jlaurens06gt. i dont c y u should have a problem getting 330+ with full exhaust. if i had ur mods on top of mine i would expect 330+

Great numbers.

PWNY where u from? i noticed the go bucks and i always have to say hi to a fellow buckeye!

No doubt there!!!!! Our mods are very similar (see mysignature)and I only got 308 out of mine, dam-mit, what the hell!!!!!!!! lol

(sorry to thread jack, but I just had to chime in)

the dyno day was a last minute addition to the weekend schedule, so I did not have time to run the full tank of 87 down and refill with 93. I would have preferred to run it with the 93. should be good for another handful of ponies.

Its interesting when you start adding up the $ spent per 1 horsepower increase isn't it?

I figure my setup has netted me in the 40-48 rwhp range. (intake, tune, udp, cops and ds) and the rough estimate cost for these (due to some installation $ in there, tax and fudge factor, bad memory) is in the 1,800-1,900. That puts it into the $40-$50/hp.

If I want to go LT headers, hi-flo cats and a nice axelback (plus install in my case) this might be another 1,500 for another 30-40 hp (the shop will throw in a dyno tune, right? haha.) That's makes about the same $40-$50/hp range.

A 150 hp TS blower setup estimated at 5k comes in at $33/hp.

Things that make you go "hmmmm"

good numbers

good number for the mods!:)

Great numbers
