Waiting on a list of mods... if you DONT have a cam or n2o then you need to find a new DYNO!

Yes, but stock just flew out the window with all those parts we listed

Damn at 341rwhp is amazing for stock the highest ive ever seen was a 02 WS6 M6( Silver) on a dynapack several years ago bone stock was 331rwhp and that was nothing short of amazing, its soo rare i still remember it lol. I know there are and could be other examples out there but for me thats the highest bone stock ive seen. With LT's and tune you should gain about 20rwhp and LS6 Intake another 5-8 rwhp, either way GL

u have something internal done without knowing.

**SSwt00SS** · 02-19-2009, 10:18 AM

skip the Ls6 intake. once you tear into the engine by adding a cam and heads, then FORGET the Ls6 intake entirely and get a FAST 90/90 or 92/92. trust me on this one. i speak from experience. do it once and do it right. save yourself time, money and resources...

btw, those 'stock' numbers are off the wall high...stock my car was 325/330...

**basballny2** · 02-19-2009, 10:19 AM

even 325 rwhp and 330 rwtq is high IMO

**Y2KPewterSS** · 02-19-2009, 04:48 PM

I have witnessed a stock 02 M6 SS pull 350 RWHP on a perfectly working dynojet. It was an anniversary edition that did have a lid, but it was a legit 350 from a stock motor. Ran about a 12.8.

**mpfranks** · 02-19-2009, 04:58 PM

what is the average that a stock car dynos at?

**basballny2** · 02-19-2009, 05:01 PM

from what ive read 290-305

**karpetcm** · 02-19-2009, 05:04 PM

Man i only wish mine would dyno that high to begin with, lol. With the mods i have im more then happy with the RWHP. I guess i need to save up for some LT's and hope for 350rwhp.

wow, and some have pulled 350rwhp... kinda suck if your car stock was one of the ones under 300rwhp

**blackbirdbrain89** · 02-19-2009, 05:30 PM

the lowest one ive ever seen is like 285 and thats one a mustang dyno(lower numbers) dyno jets are better for hp numbers but a mustang dyno is better for tuning due to the mustang has a load on it and a dyno jet does not

found my first (2) ever dyno run sheets when my SS was bone stock. found them unpacking some shit that has been packed in storage for about 1.5 yrs. ill get them scanned in and posted up for you.

1st run: 327.2/328.4 (HPPIII tuned)

2nd run: 325.6/330.3 (retuned to stock tune)

this also goes to show that the HPIII tuned did nothing for my car at all. after i took it back to stock right there on the dyno, i sold the thing and used that money to put towards my cam packing that i ended up buying in June '06...

numbers are SAE corrected and on a dynojet dyno...
