How much does it really have at the rear wheel?? Guestimates are welcomed as well. I am also bone stock. No mods here......yet.

15% driveline reduction for a manual tranny...and closer to 20% if you have an automatic...however sinc gm underatted the ls1 pretty badly i'd say you have about 325rwhp...

only one way to find out....get it dynoed

true...or you could search to see what others have...or you can make a guess on the factory rating and their numbers and then the slp rating (20hp higher) added on to it...which would prolly only be about 10-15 rwhp

depending on the year ? and m6 or a4 ? m6- 310-315 a4-295-305 maybe 310

Mine dyno'd at 329 with a cutout.

what if he doesn't want to spend the money on a dyno and just wants a guestimate like he originally said in his post...obviously the only way to know for sure is to get it dyno'd

Well, actually he said "what does it REALLY have at the rear wheels....and.....guesstimates welcome AS WELL..." so u gave him a guesstimate, and I told him how to find out what it really has. We all know one car could have rolled off the assembly line at 290rwhp, and the very next one could of rolled off at 310rwhp. So we both covered what he asked for in his post, and as you said obviously the only way to know for sure is a dyno so that's why I posted "theres only one way to know for sure.." Thats my .02, and your .02...

Anywhere in between, like they said. Just pick the higher number, and go with that one.

fair enough...that's both answers to your question...good luck with your new found pride and joy

I say around 250rwhp.

Most likely 315rwhp or so if you've got a M6.

And since he said it has 345hp, it's an 02. So I'll agree with Unit and say 310-320rwhp for a 6 speed.

It's funny all of us who pick up the little details

ls1 1990 VN

In NZL and AUS we calculate at about a 26% drive line loss to rear, so 345fwhp = 255rwhp.

just done a check. rwhp to fwhp= + 25% fwhp to rwhp= - 20%
so 345fwhp should be 276rwhp approx.

nasty99WS6

A ls1 could make 255 rwhp with two plugs missing

blkZ28spt

Lowest any LS1 will dyno is ~285 rwhp. (98 or so A4)
