engine rated at 177WHP and 138TQ
my better numbers before the tranny change and the dyno setting where between 14.6 to 14.5 @95 or 96.
Now almost all people said that with the SR16 tranny i should be gaining MPH on the track but i'm experiencing the opposite.
Today i just arrived and the first run where 14.4@95 and another one of 14.3@94 and then all over the night my runs where of 14.3@95 mph constantly with tires set to 15psi and awful threadwear over 400...lol. But after leaving the track i added the air to the tires and did a last ride and my numbers where 14.5@96.8 almost 97 with tires at 30psi of course the tire spin where huge.
Also i notice that the track reading gave me from 94 to 96 and all my passes i was seeing on the speedometer just when i hit the light a 100MPH reading... is the Speedometer that WAY OFF reading??...
Thanks any advice is welcome!
well if u do a dyno pull with your tires set at 15psi u are going to have less power do to the drag of the tire. and thats y u are getting a low MPH because of the drag.
