I'm thinking of moving from the Sportsman class to the Street class (12.00 or slower) in the Summit Series. The main reason is, I'm rather tired of being one of the slower cars in the class (11.6X's). I need new tires this year and am thinking about using a DOT tire rather then slicks (I'm thinking Mickey's ET Streets, I have no desire to experiment with radials), and re-installing the exhaust system. I need to slow the car to run in the low 12's, preferably 12.0X-12.1X. However, I'd like to run close to the same mph, around 114 mph. I have a B&M 2000 stall converter I can replace the 3700 A-1 converter with that I'm now using, in the hopes that ET will go up but mph won't drop.

So here is what I'm thinking:

ET Streets
Exhaust system with Dynomax Ultraflows
2000 rpm stall
Perhaps changing the shift point from 7000 to 6000 rpm, although this could lower the mph.

I still want to be able to make a hard full throttle launch and not have to feather the throttle. I find it very hard to be consistent doing that.

Car specs:
355
Sportsman II heads 63cc, 200cc
10.45:CR
296/305, 246/253, 108 LSA, 102.5 ICL 296AH-8 Comp Cam
456 gears, Locker
SSM lift bars with 1" sway bar
Moroso front springs, no front sway bar
CE adjustable shocks front and rear

I'm also thinking that a non-electronic throttle stop might be a good way to go but it will probably cost me MPH. Changing gears isn't likely because of the cost.

Any other ideas?

Pat, I was running both street and sportsman for a while this year. I could run 12.06 at 109. that was shifting at 6000rpm instead of 7400. It runs 11.8 at 111 WFO. I hated the street class. Racing 17 second slugs is real tuff. I actually forgot which light to look at on the tree..lol. I think if you added a little ballast and took a little timing out you could run 12.0 and still have good mph. On a side note..I managed to hang on to second in the points race http://www.reddingdragstrip.net/main.php?p=points

I'd just like to chase 'em down instead of being chased all the time. Plus, they get the opportunity to red light first. I'm not sure I'll like it either. Going fast is fun and getting a new best time is very satisfying. I'm a bit concerned that ballast would effect the MPH more than the ET.

Pat, just short shift it to increase e.t.'s.

So, let me get this straight....you WANT to go slower? tongue.gif

Hell, Pat, I'll just swap motors with ya.... :D

Justin, not slower just less quick smile.gif .
