Title: Head's Up Performance's Dyno. Post by: Taylor on June 12, 2013, 11:36:29 am I was down in Orange County on Classic Friday, with my motor in tow, ready for a dyno session at Head's Up Performance. I ran the motor there last year and wasn't happy with the results. It wasn't the session, it was the motor. I didn't get a chance to test the sort of things I was hoping for due to some issues I was having with the header and a rocker stud failure. Well after some time off from it I started getting it back together for another session. I got it on the dyno Friday and got it running again. I didn't change anything from last years runs figured we would start with a new baseline. The weather was almost the same, only 4 degrees warmer and the time of day was the same. On the first pull the power was within a few .10s from last years pulls. I dont mean peak power, I mean every increment from 5000-6500rpm. Roger's DTS Dyno is amazingly repeatable!!! With this kind of accuracy I was very confident that the changes I saw in power were real and not the result of some calculation or factoring.
Anyone who is down in the Fullerton area and want to dyno their motor and test different things, you would be crazy to go anywhere else. As a side note, I would like to thank Mark Voegtly and K-Roc and Cameron from B.C. for stopping by for a minute to check out the action.........and then staying for a couple hours helping me disassemble and re-assemble my 48's a bunch of times to change things. I'll get some T-handles Darren!!! http://www.youtube.com/watch?v=8qBlBMeUhTQ Title: Re: Head's Up Performance's Dyno. Post by: Torben Alstrup on June 12, 2013, 12:26:06 pm Most newer dyno´s, are very repeatable. It is just as much down to the calibration and consistency of the operator. But good to hear that you got what you wanted this time. Bolting engines on and off the dyno is´nt the most fun.

This story makes me want to rip the motor out of my car for some dyno time. All of Taylor's power gains were made by tweaking the 48 IDAs. It was great to see the Heads Up dyno in action. I liked the way you were able to see small gains in power with each pull. And with each small increase, eventually add up to a major gain. Taylor, you should give the audience an idea of where you started, and where you ended up. |
