I took my 2008 base Auto ls3 to Lingenfeter
Last summer for kooks 1 3/4 headers cats
Halltech cold air new OEM plugs and wires
And a mustang dyno tune.

368 RWHP on a Hot muggy day ( humid 85° )

This seems low from what I have been reading
even for a mustang dyno and a Auto

Car seems to run fine feels a tic faster hard to say.

(Lingenfeter in wixom mi)

Is this low ?

That's low....those are stock dyno numbers. Take it to the 1/4 mile track and see what it runs. My a6 ls3 c6 trapped 117mph stock and 121mph with headers xpipe, intake and tune. I never dynoed the car but mine gained alot with simple bolt ons and tune.

Local dyno would show like 320rwhp on a manual LS3 C6... that thing is a heart breaker.

What matters is how much it changed (trap speed obviously tells a lot too)

skar

What was your time .

Nooch8it

I went from mid 12s to high 11s

skar

Wow nice .
I will have to take it to the track this spring .

skar

? If it's true mustang Dyno read 11 to 12% lower then a Dyno jet the numbers look better .

368 + 11.5% =410.3 Rwp (A6) Guess I need to find a Dyno jet or go to the track .

Just go to the track that will give you real world data. Dynos are good for tuning.

376 rwhp bone stock down to air filter on my A6 on a dynojet.

376 +15% drive loss = 432 that's spot on to factory numbers .

Except the part where he is not "factory". Headers, intake, and Lingenfelter dyno tune should net ~30whp on LS3.

Dynos aren't created equal.

I just had my LS3, A6 Grand Sport dyno tuned. It runs great and the economy is better, but the dyno numbers were disappointing.

With Kooks long tubes, catted x-pipe, and K&N CAI, it dynoed at 359 HP.

My installer warned me, in advance, that the tuner's dyno (Dyno Dynamics) is very conservative.

The tuner is regarded as the best in the area. My installer races Vettes. YouTube has a bunch of videos of his running 8 and 9 second quarter-miles. This particular tuner has done all of his tunes.

I had a 2008 LS3, A6 coupe dynoed on a Dynojet dyno several years ago. It's only modification was a K&N CAI. It put down 383 HP.

Not So Fast

Gee this all sounds familiar :lol
I'm over it Alan, and I think you are also as you've clicked in on my thread in general discussion about Dyno Day
Good luck
