Normal numbers??
Normal numbers?? So finally finished my long time project
2002 ss fully forged internals
Tick sns 3 (235/243 111lsa) , stock 243s, ls6 intake, 42lbs injectors, aeromotive 340lph with Hotwire kit, btr 660 springs, trunion upgrade, ls7 lifters, 1 7/8 long tubes off road y. All through a monster stage 3 and a mwc nine with 3.90s.
Was really hoping to at least break 400rwhp almost wanted to set the car in fire when it came back at 379
What could be holding me back in this case ?
Or is the rear end robbing me of so much power ?

I am running the Tick sns 3 mild lobes in my 98 m6. My only mods are ported throttle body, stock 1998 heads, long tubes, SLP lid, ory pipe, flowmasters and a ls6 intake. I put down 390hp and 380tq on stock 3.43 gears. I am running stock injectors and stock clutch also. I only got 60,000 miles on my car.
A lot of it can come down to tuning, I'm no expert but that is what my numbers were after my cam install.

Have you had it to the track? What does it run?

As stated I wonder about the induction/exhaust.

Sounds like a few limiting factors. With a cutout, speed density tune and ud pulley you would be over 400 imo.

even with all that stock stuff on there and with that 9" it should clear 400 rwhp on a properly functioning/calibrated dynojet. if it does indeed have 243's,with that cam i would expect it to clear 400rw also. you have room to grow for sure. as already mentioned, with a bigger maf/lid or going speed density,good flowing exhaust or a cutout, ud pulley, and if funds allow,finding a 90/90 setup should put that combo around 440-450 rwhp.

yeah,something seems to be wrong. just an example, my junk when it was stock other than some cheap *** 1 3/4 headers, hooker catback and a 228 cam made 383 rw with a stock rear. that cam of yours is quite a bit bigger and those 243's should more than make up for the power loss of that rear.
if it was an auto I would tell you not to worry but that seems low for your mods, I would def expect 420ish rwhp
the curves look good though, could be a dyno issue with the weather station or other calibrations?
what air fuel ratio and timing are you at? should be ~12.7:1 and 26* (plus or minus a couple degrees)

Could always wait until you get some track times later on. Might just be the dyno.
I've seen a dynojet in person that read 30rwhp+ low repeatably with several cars who had dyno sheets from other dynojets. **** happens. Left a lot of people at the dyno day broken hearted.
