Dyno Testing SS Engine??

[Mike Taylor 3601]

I concentrate on average tq.hp. #'s,I do that because if you are more focused on peak numbers you are more likely to miss small gains,many time you make good gains at the peaks, but lose below or above peaks and end up not really making car faster.
you can't move peaks around much without making air flow or cam changes.

If it doesn't pull off the gear change it will be a slow puppy.

I'm with Adger, that's what I have seen. I found more ET improvements working on torque at the RPM mine falls back to on gear changes, and where my converter hits. If you have not run it in the car, I'm not sure how you would know where to work. The rest of it seems to be for MPH. Compared to what I found at the track before the dyno, I gained almost an expensive tenth. Fun day though.

I suspected torque from converter fall back, up to shift points was the best RPM range to concentrate efforts.


Any estimation of how small of gain would be noticeable on a time slip? e.g. Would an average of 5 ft/lbs from
5400-7000 even show up? Less?
Thanks for the responses.

It all depends on where you are in the HP spectrum. At low HP, 100 more will make you a couple seconds quicker. At high HP, 100 won't get you a tenth.
