A.what kinda kit you have what psi you run and how much hp often you drive it hard you drive it or highway miles
E.whats your average mpg
F.any other comments you have about everything you've done

Thanks, Matt
A. E-bay $275 turbo gt2871 clone, 9 psi daily, 12 max
B. Summer mostly
C. Not hard enough to gernade an e-bay turbo
D. Mostly city
E. So far 21.98 mpg with 1800 miles driven

F. Other FE mpg breakdown as follows:

27.90 Stock Injectors, with tune (41,000 miles)
28.82 Stk Inj, underdrive pulleys (7400 miles driven), ongoing tune
27.37 42lb Inj, UDP (4070 miles)
23.94 Stage 3+ South Bend clutch with LSD installed, DW Conti tires (2500 mi)
21.98 Turbo with all above (42lb Inj) (1800 miles)

I don't quite understand the 3.43 mpg drop with a clutch, LSD and DW Conti p225 tires, but I have brief data that shows loads increased with the clutch and LSD install without the new tires. The installers bent the clutch disk the first time so I regret letting them do the LSD. I am fairly convinced that the preload is not correct, contributing to the increased load, but the trans is still turning. Hiway loads are higher and deceleration rates are higher, pointing to a rolling load increase in the trans.

Has anyone else seen a substantial FE drop with an LSD install??

Anybody have a good SVT trans installer in the Detroit area?

I keep constant FE data everytime I get fuel. The results speak for themselves....even the UDP's....dont tell Tom because that will be a whole other thread...
