today i went to get my car baselined. it made 410/394std and a corrected sae 398/383 . next is a vararam and diablosport then lg longtubes

 

for the unbelievers, show them/us the dyno chart. and I take it you mean a completely stock car, right?

 

Good numbers.

 

charts...what dyno did you use

 

Hard to believe that my LS3 with intake/LT's/axle back exhaust/dyno tune only put down 29 more HP.

 

Thats 40-50 rwhp more than some ls3's. Every dyno is different. Lets see the times.

 

it was a dynojet. dont mean to rub anyone the wrong way but i
dont dyno drag. but will still put up the graphs when i get a chance to scan them. the car was bone stock down to the air pressure on the tires. it still has the factory oil in it

 

yes, but if you go back to july '07, the first ls3 were anywhere from 370 to very low 390s. and those were from tuners, lgm, mti, etc. plus as said by op, dyno numbers mean something but not everything.

 

Not to offend anyone but I have come to the following conclusions based on what I have read here...

Mustang Dyno's read low. (actual RWHP is higher than these show)
Dynapack Dyno's read actual
Dynojet Dyno's read high (actual RWHP is lower than these show)

This is just my opinion but if I had the time I would like to take my car to all three and prove the above. The OP is putting down 410 stock? I have CAI. LT's 160 T-Stat and Dyno tune on my LS3 and I got 412 HP on a dynapack dyno. I have seen others say they ran 425 HP with the same exact additions that I have. The OP would probably show 435 HP with these additions on the same dyno.

I just can't believe the "official" advertised numbers are off by that much so that is why I concluded the above. The only other thing I can come up with is that tuners are somehow manipulating the dyno numbers to suit their own needs. I'd like to believe that tuners are honest so again, I have to conclude the above. I guess the calibrations can be off on some dynos and maybe that explains the wide range of numbers we are seeing.

Some here will say "Take it to the track to see how fast it is" while I agree in theory, every driver is different and some may be better than others at drag racing. The dyno should take the driver out of the picture and focus solely on what the car can do but with these wild number swings it does not seem to be the case.

(Flame suite on... be gentle and remember it is just my opinion)

 

Remember, A dyno is a great tool to monitor engine performance. Don't get caught up with the numbers...and try to use the same dyno with changes to car. Switching to a different dyno will show different results. some you may like & some you may not....................Great Numbers & Congrats...........Joe

 

Those are "fantastic #'s I had my LS2 just done it made 355 ho with only a 160 T Stat... I've had it on the track, and ran 12.52 @ 112 on Runflats... My MT Drag Radials just got here, & I'll run it next Sat.. at Englishtown..

Nice # see what it runs at the track...

 

I'm in 100% agreement.. I just sold my 96... I bought it new, and NEVER had the heads off... with only the following mods it ran 12.28 @ 110 mph, & on a different track it ran 112 mph...

Mods were 1.6 RR from GM... Breathless Intake, Muffler eliminators, 3200 Vigilante Converter, 3.73 Dana 44, & lightweight Weld Pro Star Wheels... it had stock heads, cam, and STOCK Exhaust manifolds running through the cats..

The trick is NOT only HP but the "Overall Setup" a car has to have the correct combination of parts to run good #...

I never had that car on a Dyno... My 05 LS2 has run 12.52 on run flats leaving from an idle.. I'm having "BIG" problems with the Torque Management system taking timing out and slowing it down..

I plan on a 3200-3500 Converter over the winter, and hope to be running right around 12.00 without adding headers or exhaust.. I also don't want to go to skinnie front tires as its a very nice car to take on trips, & I'm getting 26-27 MPG on the highway

It has 3.15s now but if I have to I'll go to 3.42 (Prefer not to go to 3.73) as its 100+ miles one way to the closest track)

I've raced in the Corvette Challenge at Englishtown since it started in 1998 or 99 and have always finished in the top 10 with over 100 points racers every year.. My eventual goal is NOT 11.00 but any # around 12.00 and Consistent is # 1.... my 96 would run within .02 - .03 every run, I'm sorry I sold it before this season ended this Nov. however I hot a helluva price and its water under the bridge...

I sure as hell managed to take this "off topic" sorry.... But my point is Dyno # do not mean squat if your are bracket racing, CONSISTENCY is what counts!! IMHO a Dyno is a good tool to see how much of an improvement a mod has made, make a run before & after...

The Real Test is at the Track!!

 

Don't listen to the typical LS2 haters.. I put down 400hp/386tq when mine was baselined. w/ LT's, CAI, 3"Z06 Exhaust, U/D pulley It made 426/425. And by how bad it rapes a similar modded LS2 car, I believe the dyno. Congrats on the #'s!!

 

thanks jpee, silvr, and jt metal for the support. I actually went to the dyno expecting 370rwp. wether my car made 350rhwp or 410rwhp that still would change the fact that i would go toe to toe with an 11 second car. That doesnt mean my car runs 11s but im comfident in my driving and the dyno is only used to monitor the progress of some mods

 

Non of you are mentioning which one your car is. I am assuming they are M6. I had mti atlanta tune my '08 A6 last week. The baseline was only 340 something! After the tune it was 364 hp and 386 ft lbs torque............Whats up with mine?

 

I would tend to disagree, I've always seen the dynojet with its SAE corrected numbers seem to be in the middle with the Dynapack being highest. However, even dynojets vary, high to low. Of course I'm no where near a SME on this one. Just my experience over the many years of owning my stangs and Vette.

 

stock car? that's insane!

 

Thats nothing another ls-3 stock with tune makes 419 rwhp

 

Those #'s sound right for an automatic to me.. Nice tq #

 

Similar to my 08 a6 before mods.
