The 80e is definately going to cost you sometime. It horrible out of hole. I think you have the power to run a 10.90. But that 6 speed probaby has to go if you want a 10. How many gear changes, 3 or 4? Cheapest and easiest is a th400 with a stall.

 

I agree, I was thinking of having rossler build me a 4l80e with the 2.75 1st gear. But I think I would perfer the 6 speed auto of the th400 and GV unit. I think I will be going that route at the end of the year.

 

Or the new 6 speed auto, probably more pricey, but an option.

His meth is probably fueling a good portion of the demand.

 

All I have is the stock fuel pump+255 inline+boost a pump+alky dual nossel+42-43lbs inj. I dont know my duty cycle, I keep forgeting to ask. It still needs work in the tune.

 

How come you are only at 78mph at that rpm? Those don't seem like 4th gear pulls to me? Are you sure you were in 4th, if not then those numbers should be higher. Also I noticed it says flywheel hp/tq, where did you guys come up with the correction factors to get fwhp/fwtq? Why not just use rw numbers?

 

It is rwhp, for some reason (I dont know why) but the graph always reads fly wheel hp. I remember the first time I got dyno tunning from Synergy, as soon as I got home I read the same thing fly wheel hp. I called up Rick and asked are pulling a number on me and he said that it says flywheel but it is rear wheel hp. I double check, with a dynojet and the numbers are preaty close. The dynopack normally is able to put a harder load on the turbo and boost comes in alittle sooner, but the numbers are close. As for the MPH, my speedo is not reading right. Ever since the 6 speed swap. It is SAE corrected. here is a dynojet dyno on 20psi.

 

Synergy graphs all print out saying fwhp but the #'s are RWHP for sure. He really should correct that!
