Finally after 10 race seasons Im going to pull and rebuild/replace my trusty and faithful mild built 727. I am at a place of question though. Should I spend the money on a transbrake valve body? The setup is a Duster with a 408, converter from Cope that flashes to 4500, Caltracs everything, 28x9 M/T slicks, 1.58-1.68 60' (depending on the track conditions and elevation), running mid 11s on the 1/4. Surprisingly I am leaning toward 'no' even though Im a competitive non electronics racer. Here's why:
1) I have set up front a rear line locks with a two step from the Mallory box and a button just like a transbrake car. Only drawback is my launch rpm is limited by brake holding power. Typically it's set at 2700.
2) More drivetrain abuse from the sudden shock compared to a preloaded launch. I'm still running the factory 8 3/4 axle shafts that I'm sure wouldn't live long behind a T-brake along with other parts. Moser shafts are on my to-do list, but I'd also swap bolt patterns at the same time which means new wheels as well.
3-5) Money money money
Do you guys think I'd gain any real performance over launching off the converter? With the system I have now Im consistantly hitting .010-.030 reactions with an occasional double 0 when I'm on the game. At the Divion 6 finals last weekend I won rounds every day, and made the finals Sunday (12 round wins that weekend, 7 Sunday losing to a guy who ran dead on the dial with a matching .013 light to my breakout). Plus I'm first in points at the local track going into the last race. Winning that would give me my second no-electronics/Pro championship in a row. I'd say the setup is working well as is.
So either talk me into the trans brake, or out of it.
