Stock GXP dyno

[99-LS1-SS]

I was able to get a stock dyno run in before my headers were put on. Here is the dyno sheet. I'm tired and dirty so I'll post up the exhaust stuff later.

All in all, I'm pretty happy with the stock run. It made 358.11 rwhp and 365.84 rwtq corrected. Uncorrected was ~375 rwhp.

Here is the sheet.

Here is the video. It hasn't finished "processing" so it might take a little while to work.

So headers VMS 93tune and a cai on a GT should put them on par.

Probably will. In 2 or 3 weeks I'm going to go back and get it dyno TUNED with the Vararam and ARH headers on it.

So about 50 more minimum then a stock GT. That car is gonna rock with your future mods!

very nice numbers for a stock car. Im jealous :D

Or about the same as a re-cammed L76.

;)

Even the smaller cams make 400RWHP with basic mods, but I expect Brandon to hit real close to that with his mods. Too bad for him I am going for closer to 500. :nah:

[99-LS1-SS]

Eventually, I will close to 500 too.

Nice!! That should put you with in reach of spanking GT 500s

[99-LS1-SS]

I hope so. Now I just have to find one to race!

[Mike@NewEra]

Nice dyno numbers. That is what a GT with an auto trans would make with intake, pulley and ARH headers tuned. I bet for sure you are going to be well over 400 rwhp with an intake, underdrive pulley and tune, should be around 415 rwhp plus or minus a few.

a stock 6m gxp could beat a gt500 if the right guy's driving it. they might have power, but their chassis/suspension sucks like it always has on mustangs, they're ditch magnets. i can't believe people pay $40-50k for those trailer park lawn ornaments. congrats on the gxp.

Feel free, I hate mustangs, anyone wishing to spread the anti poonstang word can be my guest to any of my nicknames for those mobile mullet death machines.

How many miles were on it during the dyno pull? Ours made slightly less than that and everyone said our numbers were very low.

It had right around 600 miles on it. They guys at the dyno said it would "loosen" up and dyno higher with more miles on it.

The correction factor was .95. Not sure if that had anything to do with it or not.

Ours had 19 miles on the first baseline and made 351 RWHP / 361 RWTQ. It now has 1,000 miles and no mods and it made 371 RWHP / 382 RWTQ.

Damn, you guys are driving the hell out of that thing! Is your correction factor set or dynamic? If so what is it? If you can tell me.

More like beating the hell out of it... :woohoo: We can't wait for the track to open so we can get some numbers.

We use SAE correction factor.

Nice. Nothing like getting to run the hell out of your car....and only for it to get faster time!!:devil:

[sharkie]

All the Vette tuners around here say that the abused ones make better numbers. I say get 500 miles, then whip it like a red-headed step child!

:whipit:
