The only true and accurate dyno is your timeslip.

 

The only thing that matters is how the car performs in the real world and if you are happy with it. A number on a piece of paper or a computer screen won't change that. Dynos are useful as tools to aid in tuning or for internet bragging rights.

 

Precisely why I haven't dyno'd my car. It's an old N/A, so I know the numbers are low, but I like the car and it's fun to drive, so the numbers are irrelevant to me.

 

You guys can argue dyno numbers all you want... And that's why debates like this happen.
Dyno's are tuning tools but yet everyone want's to compare their results to others who dyno on different dyno's.

I use time slip/track results for true meaning.. My Mainline dyno like other Aussie dyno's read low when compared to Highly inflated Dynojets.. I have done multiple back to back tests with a local dynojet to verify my results and I have found anywhere from 20~25% needed to be added. So if you wanna compare to the inflated dynojet numbers you can take my advice and add that to my results.

If there's anyone who wants to challege my finding's I'd be glad to show you..

 

Food for thought.. At 32 Psi my own car makes 611hp on my dyno.
I have gone 8.6's multiple times at over 162mph.
My car weighs 2500lbs.

Do you think my car really makes 611hp?

 

MAINLINE DYNO READS lower then most other dynos especially dynojet. enzo is on the money

 

true!

My old NA I had would do a high 7 in the 1/8th mile but run in the 15s in the 1/4

 

hey enzo thanks for chiming in. i spoke wit jim at jpr and he was very impressed with the tune,and said your numbers were good. were going to do a power run. he wants to see what im almost exactly at. so he can figure what my new motor should produce.

 

At 162mph traps, you gotta be making a lot more than that (like over 800).

 

My roommates supercharged Miata makes 5lbs of boost at home at 2700 ft. When we're cruising on Santa Monica (sea level) it'll make 8lbs... Superchargers make less boost at altitude period.
