Dyno #'s on recent H/C LS1 upgrade

Just finished mod'ing the LS1 with LS6 heads & 220/220/114 cam. Six speed with shortie headers & honker. Pretty mild stuff. Here are the numbers:

Well, that didn't show up very well!

372.9 ftlbs 99mph 4801 rpm
378.4 hp 118mph 5744 rpm

Wish the numbers were bigger, but this result is very streetable and decent hp gains over the stock LS1

Not bad

Just gives you areas to improve, that's all. Throw on a set of long tubes, high flow cats, and an underdrive pulley. You'll pick up another 20 in HP and torque.

Very nice indeed! Much more bolt on's out there to make her jump up even more look forward to seeing more numbers!

Thanks,Matt

Also, those dynapacks are a bit more conservative than a dynojet I believe. I think you'd be putting down a bit more if you rolled the car on a dynojet. Regardless, those are great #'s. 445 crank hp...NICE.

Mustang Dynos read the lowest. Dynojets can read up to 10% higher than a mustang dyno. Dynapacks read higher than dynojets. I am not sure the percentage but they read the highest usually. Dynapacks give the highest numbers because you have to take the wheels off of a car to connect to one. I believe they connect to the wheel studs(i think), where as dynojets and mustang dynos read the power with the wheels on the car. So taking off the extra weight of the wheels inflates dynapack numbers.
