Normal dyno?
Well we just dynoed our 01 vette with a blackwing and throttle body and new exhaust except headers and X-pipe. I was just wondering if the normal dyno for an LS1 is around 300 horse. Ours was around 292 horsepower but around 297 torque but it was a nice arch though. Just wondering what your guys' dynoed at?

Re: Normal dyno? (1969stingray1969)
Here are the results from my dyno runs. The exhaust was still stock at the time. They did 5 dyno pulls. The first 2 are with the stock air box and factory filter. Pulls 3,4+5 are with the Widemouth.
Dyno pull 1 = 299.3 rwhp
305.2 rwtq
Dyno pull 2 = 294.2 rwhp
299.9 rwtq
Dyno pull 3 = 311.6 rwhp
316.8 rwtq
Dyno pull 4 = 312.8 rwhp
319.8 rwtq
Dyno pull 5 = 313.3 rwhp
321.1 rwtq.
I figure for 200 bucks this is not to bad. Overall i am impressed. Also it really brings out the sound of the engine. I can feel a difference. Maybe it is just because I want to feel it.

Re: Normal dyno? (1969stingray1969)
I just think Its Bull crap that most of the suppliers of bolt on parts a lying to us about the HP gains their product. I encorage all that have dynos with bolt ons to post their gains and on some cases losses, so we all stop buying products like the Vararam with its HP gains of 40 HP, or the GMAF with there gains. Im sure they MADE a car or two with such gains. A corvette magazine dyno Vararam and should it 12 RWHP.

Re: Normal dyno? (phils C5 vette)
well phills they probably rated the horsepower gain after it got tuned which i have not done yet so stop getting all annsey. I know a guy who did less than I did but put headers on but no full exhaust and he had it tuned and it came out like 322rwhp. So you would have to get it tuned. Which I am in the process of doing when I find a local tuner. Or in OKC :nono:

1- Hot Run vs. Cool Run : Hot = Less Power . Some people take the Base Line @ Hot then compare to a Cool peak. Gains look :crazy: .
2- Daisy Chain/Rapid Fire Runs . Again causing similar effects like above.
3- Time of Run. Afternoon vs. Evening. Denser air = More Power.
4- Reprogramming the weight of the Drum.
5- Changing Elevation value. NA engines get really affected here.
6- Load changes by tightening or loosening tie-down between runs.
7- AC's coming own would cost a few ponies.
8- Some even go as for as switching charts to impress with after pulls. :_dupe:
Just felt like sharing this info I got off Turbo & High-Tech Performance Mag.

Re: Normal dyno? (V8_Club)
It was an afternoon run and we did a pull right away then let the engine cool down and the peak horsepower wasnt on the cool run but the cool run had better torque and curve

Re: Normal dyno? (1969stingray1969)
There is definitely a lot of difference from one dyno to another, I've decided to always use the same one each time I do any mods. My 1999 bone stock FRC pulled 319.6 RWHP, I've since added Andy's (A&A Corvette, Andy rocks!!!) stage II heads and cam, FLP Headers, ZO6 Intake, removed the cats and added an aluminum flywheel, also changed to 3:90's which will actually rob a few RWHP. Anyhow, my new dyno (did it today!) was 393.6 RWHP. A lot of people will try to add up HP in a cumulative manner (ie. intake 10, headers 15, heads 50 so I should have another 75, just doesn't work that way, plus most HP quotes for mods are quoted at the flywheel and not RWHP).
