B.how often you drive it
C.how hard you drive it
D.city or highway miles
E.whats your average mpg
F.any other comments you have about everything you've done
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...
