What an incredible self-build! I think I need a turbo upgrade! Also what would I gain with a 4:11 FD? Whats the OEM ratio?

This is why i am going 4:11. It is the only war to go if you have a stroker with bigger turbo. Longer gears FTW Also better highway mpg!! Big bonus in my books

I put together this chart to display differnt shift points and where you will land in the next gear (rpm and speed in mph) Simply pick your shift point and check it out. Speeds may very, as this charts speeds are for 275 35 18 tires

Can I ask what your peak timing was and what your air fuel ratio is at on E85. We just finished up a very conervative road tune at 40lbs on my 6266. Car feels scary fast on my 2.0. AFR's are in the low 11's and peak timing is super low.

Going to the dyno soon, just trying to get a gauge of how far you pushed your tune to obtain these numbers. Thank you sir.

The timing starts around 5 degrees at peak torque rising to 11 up at the top of the RPM. AFR's are around 11.8:1. My boost is not 40, its 35-36 peak to 34 up top on my setup. Post up the numbers when your done!

Just did a 3rd gear pull on a 1.0 correction factor Dyno Dynamics at DB performance during a spring dyno day. Spool up is awesome, nice and wide power band too.

I might be force to if my 1G is not ready, still waiting on a replacement 300m Xfercase. I was not going to drag this car, but I'm interested to see what kind of trap speed it could hit?? When do you plan on going next?
