Before I went with the big wheels and adding the top, I was getting close to 28-30 mpg with the turbo kit. Over 34mpg with the turbo kit on highway. Last 3 tanks of gas, I am getting just over 26 mpg, mostly backroads or city driving.
ZZP TURBO- DDM TURBO
I'm trying to make a decision on turbo kits- PROs & Cons:
ZZP
PROs-maybe:
inexpensive
includes exhaust
lower boost level
due to inherent rear traction loss-this might be perfect (1lb. of boost=10-12 hp),
6-7 lbs of boost= 60-70 hp, do I need anymore? Is this more usable power (passing and making 5th gear more usable).
Less cylinder pressure for a non-forged internals motor (hold-up longer if programming is spot on?)
Cons:
use existing injectors @ static pressure
not enough history in slingshot community.
DDM
PROs:
Proven
Excellent customer service
Borg Warner Turbo
No core charge on pre drilled oil pan
Bigger Matched Injectors
Starts off @ 9lbs +/- of boost
Cons:
Price
Approx $1500 higher than competitor
Have to purchase exhaust @ another $1500+ (now this makes it double the competitor's price)
Going to have rear traction problems (tires)
What would you do, pay an extra $3k for a little more HP?
I might be missing something here, so please can Dave and/or Kevin chime in (haven't heard any non-biast veiwspoints) or any other turbo slings.
Thanks,
Fred
