[we4Mateo]

...

V6 power has a 6262 with ported irons trw pistons flat tappet 208 cam with a stock location stretch i/c and it runs 6.80's in the 1/8 @ 25-26 psi on pump gas and alky.

Nice!

...A board member by the name of Toomanymods runs 18-20psi on 93oct only on a Weber built motor. I think he introduced the motor to Alky now...

With my old 6765 I ran 18-20 psi. Now with the new 6466CEA turbo i'm running 20-21 psi on 93 oct only. I took it up to 22.5 psi then started seeing a blip here and there, so I lowered it back down. No alky yet. The combo runs very strong on straight pump. I read a thread on other site where a guy ran a 10.23 at 131 mph on straight 94 octane, no alky. He's running a 70GTQ, .85 A/R, 4-bolt turbo with about 3500 stall. Impressive. Stock crank, rods etc.

the most boost that i can get away with is about 19 psi and 18 degrees timing on 93 only. it's been a 6.77 @ 102 in the 1/8. combo in sig

If you think about it, pretty freakin amazing the power these motor's are putting out.... love driving mine on the street and do it all I the time, as long as the roads are dry. I'm hooked on alky and 25/27 lbs boost, 23/21 timing, all the time.

I would love to drive my GN. It is up on a lift waiting for a gasket to solve the oil pan leak.

With no boost control I couldn't run less than 21-22 psi on stock waste gate. Had a hint of knock so i changed to an external gate and backed it down to 18psi on 93oct only. Not even a hint of knock rock steady 11.5 A/F

Only running 23-24 psi.

I routinely run 7.1s in the 1/8th bracket racing my car with the 6262 JB with ported irons, stretched slic, flat tappet cam, alky and TT chip. Boost and tune is very conservative on a 1.6 launch.
