Negative on that... DynaPacks read lower than mustang dyno's.. not by much.. but they do. My best friend/neighbor owns a dynaPack. I run the machine..most of the time, we were both trained on it, by Dynapack themselves (they fly out and train you for 2 days). We have done back to back testing with our dyno and a local mustang and a local DynoJet.

DynaPack is consistent every time, and read lower, mustang read a tad higher and was pretty consistant.. DynoJet was all over the place.. plus we can fudge those #'s pretty easily to get higher hp ratings. Cant fool a DynaPack since your hubs are directly connected to the machine itself and it uses fluid dynamics to measure torque then calculates HP.

I made 330/347rwhp/tq in a 98 A4 Z28 with stock heads, 218/222 cam, shorties, lid, ported TB, LS1 intake, stock converter, pulley, ORY, and stock catback.

If you want to remain delusional then I am not going to be able to convince you.

I wish it were true though, but its not. Sorry for the threadjacking!

I agree with the other posters though, that you need to get the car to the track. Dynos are only tuning tools, the real measurement is on a timeslip. If the car is running good i the 1320 then it is fine, take it somewhere else and get dynoed for peice of mind.

i found your problem, you're not using an ls1.

do you have a graph? i agree that dynos are tuning tools, nothing more.

i'd guess my car to come up ~310 rwhp unlocked on a dynojet, but that means nothing as the car consistently runs 12.2s @ 108/9 dragging 3,500 lbs.

as long as the a/f is ok, take it to the track and see what you come up with before you get too worried.

You still haven't stated whether you are M6 or A4.

Your numbers still seem low. I've seen stock 01 and 02's dyno not much less than you on Dynojets.

the LS6 cam is 204/214 550"/549" I made 360rwhp untuned throught stock heads and bolt ons on a dynojet in the hot sun on a trailer in the middle of a parking lot in June. Granted I Also had the 1.8 rockers which make my like 583"/579" That does seem low to me Althought the lift on that cam is pretty small

Then you were trained to calibrate the dynapack for the numbers to be on par with other chasis dynos. It's not physically possible for a car to dyno less power when you remove the tires, simple laws of physics. You're eliminating 50lbs + of rotating mass. I've had my car on a dynapack and a dynojet. considerable difference in power in favor of the dynapack. When configued properly, the dynapack will read preet close to that of a dyno jet. The more power you make, the more vast the differences between a roller dyno and a load dyno like the dynapack will be

bottom line is that a roller dyno reads at the wheels and a dynapack reads at the axels. A roller dyno will never read as high as a dynapack or other similar dynos.

If you dont beleive me, here's a website with the actual math to prove it.
