6800+ rpm?

[Packy]

mark can i ask why dont u pull the wheels up?....

Time spent in the air is time lost!

[Mark98SS]

How much boost are you running with the D1SC?

Awesome video.

7 psi in that vid, TH400, launch off the foot brake at 4000 & thanks.



Justin, it doesn't pull the wheels like Bill's car for a couple reasons: 3.50 gear, conservative stall (~4000) & only about 3psi at launch.

hey Mark, what did you have max boost set at last year and how much are you running on the new setup?
I can't wait to actually get a look at your setup in person.

Justin, you don't want tall gears under boost.....you get more power, but it comes on at a ramp rate, where Bills car is like hitting a light switch.....instantanious full on power

[mark21742]

correct me if I'm wrong, but the thought behind the final gearing is the lower gear lugs the motor more and for longer in each gear to build more boost.....right?

[Mark98SS]

I run the 3.50 ratio to keep RPMs in 3rd reasonable at the traps. It goes thru at about 6100 at 133mph. The boost is not actually controlled like with a turbo, is a function of engine size, blower rpm & restriction in the motor. I have the same pullies on it as last year & expect slightly lower boost as a result of more displacement.

i still dont get it... if my car with your old DRs can get one tire every and 2 once in a while why dont u... hell im a stick car still and im running stock shocks and tq arm, and only hooking at 3800 on the line o well there's probably a reason but im still lost.. unless ur tq curve is not @4000 rpm and some how mine makes more... yet im running a 3.89 gear and dont have 100lbs of blower and roll cage, now an iron block... at the same time i dont under stand why my buddy in his 11.4 camaro dont pullem up.. but he needs an air bag or a drag sway bar...

[Mr. Luos]

hell im a stick car

That's why.

[Zapper2003]

At 60 it would be even better.

Moneyshot!

The auto is softer than bangin a stick, won't jerk the front as much. Pic below is hitting 2nd with the old M6

[bills98ta]

OK,,, Here's 7400, hitting the rev limiter...

Bill, that thing frickin launches, dude!!!

[bills98ta]

To bad It didn't shift into 2'nd....

[blackbirdbrain89]

yeah, that day would have been awesome if it would have made a full pass... or just gotten the time slip... and mark thats a hell of a good pic
