I find in my UrQ, that if i just let up on the throttle about 3/4 of the
way in between shifts, i have MUCH less turbo lag. I believe this is
because i then dont have the pressure spike that i would if i just shut
the throttle at 13 psi.
Another thing to remmeber with a turbo car is that you cant throttle it
like a NA car. You have to ROLL on to the throttle, you cant just mash
it. Contrary to whatou might think, if you take your time getting on the
throttle, it will actually be faster because you allow the exhaust pulses
to spin the turbine up progressively.
Anotehr thing is MUCH freer flowing exhaust. I was over at Tim
Valencia's place, and while looking at our race car, we were getting 12
psi of boost just by reving the engine. Of course, that is a K26 (stock
one), with a 3 inch downpipe, and 3.5 inch tubing coming out of the side
of the car...man it sounds great....hehe...
