Today i ran for the first time the GM 7T delta with a Mamba Max speedo and i need your advise please.Before this i have to tell you that so far i was running with this speedo a MM 7700 with FDR 7.78 ,temps was 60-63 Celsious and it was very fast.After this i was running a GM/Dr.Speed 7T delta with the same speedo and settings but with FDR 8.21 and the same temps and it was faster than Mamba 7700.I was so happy
until for some stupid reason i fried it
(i dont want to rebember this fact anymore).Today i put on the new GM 7T delta and everything was different
.To be close to the Mamba 7700 performance i have to go to FDR 5.9 and the temps are about 52-55 C.I haven't change nothing of the speedo settings yet.Timing on the speedo is on the normal position .Do you think i have to go to a ligher level with timing or gear up more? I think i'll never get the same performance i had with the Dr.Speed 7T but i don't understand why such a big different between these two motors.Seems to be the same but they aren't
.Any comments or suggestions are welcome.
