ratios

Post by hedgy »

I had 3.5 in gu 4.8. I just finished turbo now and changed my gears to 4.11. it is perfect with turbo, but if i my 4.8 was naturally aspirated still, i would have gone 4.3 gears.

turbo kit

Post by hedgy »

it is twice the car now since turbo fitted. It makes over 250 kw at the rear with 37's now. Torque is over 1250nm also so awesome for bush. Cost over 20k in total but thats stage 2 with computer, massive injectors, etc which can run up to 20 pound boost. Currently i only run 12 pound and that is insane. Engine internals are needed to run boost above 15 pound.

I'd like to see what figures you would get on a dyno run with 31's on it.
