Headers Only - Untuned - 350 rwhp I was pleasantly surprised with the numbers.
These are std numbers on a dynojet. Lid, LS6 Intake, Headers, ORY, Catback

Very nice numbers man.... Especially untuned. You could prolly squeeze alil more out of it with a good tune on it.
My 99 SS M6 with just a lid and Pacesetter longtubes made 352rwhp/360rwtq.... Tuned.

nice. I made 351/355 un tuned also. SAE corrected. Same mods as you on a low reading Dyna Pack dyno.
its weird tho cause your track trap speeds dont really show your making 350rwhp with a low trap of 107. I trap over 111.
high reading dyno???

exactly. You just helped me prove my point.
you guys have nearly the same RWHP, and look at your trap differences.
The track is another form a dyno...yours indicates your making the power the dyno said, while the OP's doesnt.

Good dyno pull. Your car has the power to trap 110+, there are a ton of variables on any track any given day to always trap good. I don't know why some of you are blaming the dyno for reading high. A lot of guys obviously have never ran on a slick track in a 100 degree weather with 75% humidity on street tires. For ex. I did with 323rwhp and ran a 13.9 at 103 in my M6. My friend, just to compare, ran his 06 GTO A4 and hit a 14.1 at 99 right next to me. This was at IRP (Indy) last summer. Both cars at easy low 13 sec cars with traction (tires) and good air. Can't wait to find a track out here in SoCal to get my 12 sec slip.

Wow, there has been a few replies here...
First of all, 1/4 mile time is with same setup, but it bonced off the limiter on the 2-3 a few times, hence the lower trap/time. (Hopefully a tune issue, that will be fixed along with the new mods) Look at the 1/8 time, I think its a little better. I think the 2-3 was right after the 1/8, cant remember exactly as it was awhile ago.
As for the SAE. MikeG chime in and correct me if I'm wrong, but Mike Norris said something about his dynojet reading usually ~2-3% lower than newer ones. So I think he said his STD numbers were closer to newer SAE numbers. I dont remember the exact SAE numbers here, since they're not on the sheet.
Also, you guys aren't comparing apples to apples when you compare numbers to track times. We all know there are many other factors at the track. The track times are from Florida. I can't remember the temp, but I can assure you it wasn't really cold air.
