Hennessey Performance Engineering

[Beefman]

Hennessey did a fantastic job on my Camaro. It's nice to have a car that can run so well. I just need to invest in a tire company and things will be great. Thanks to James and the entire group at Hennessey. I went for the 600 HP package. I found out that some Chevy dealers carry them already done. I guess Chevrolet doesn't mind them making them better.

maybe i am wrong but those numbers seem low to me. Someone just posted a ls3 with just LT headers and CIA and no tune put up 394 RWHP

Here is the link

Some things to consider... Automatic vs Manual (Difference of 5% or so on drivetrain loss)

Correction factor on the link you provided was STD which yields more power than a correction factor we posted of SAE.

Your factory L99 Automatic car is good for about 320rwhp with less than 4000 miles. Mileage on these cars play a big part!

yes i am sure there are a lot of factors but the numbers still seem low. I would think with 600hp at flywheel that u should get about 500 give or take a little. 600- 15% is 510 but like you said there are a lot of little factors to add. non the less its a great job done.

Sounds good and thank you for the comments... One small note..20% drivetrain loss is being seen from the Automatic 6L80 Transmission. Car stock is 400 and dynoed 320. Beefman's car will pick up an additional 20-30hp once he has broke the engine in.

Man, that looks really clean. Probably the cleanest maggie install ive seen yet.
