Default Re: VP - C25 vs C12 or C14

I tested C25 against C12.
Found it gave me 1 mph but lost .05 overall. Lost .10 in the sixty, .15 in the eight, but picked up .10 in the second half of the track.
This was just make 3 runs, change fuel, make 3 runs, back to original fuel make 3 runs.
I believe the C25 would be beneficial if I can do some tuning. But 9 runs in a day was enough. Later I might put the C25 back in and do some tuning. If I can get it to leave like the C12 it will be overall quicker. But so damn expensive.

Bob give me a call or shoot me an e-mail and I will talk to you about C25. Are you trying to switch to C25 for your Fairlane?

Thanks. I've seen as much as 4, and as little as 1 degree difference. Just wondering if I was seeing right.
