Good luck with the shake down and stay safe and get lots of video!
Any updates from the VIR shakedown? Video?
Quick question - do the headers your use dump into the stock 2.5" size pipes? Or did you go with 3" exhaust on the custom build?
I agree with all the posts above... I need bigger headers. And yep, the problem with "out of the box" headers is the engine is set right against the firewall. Depending on the dyno session tomorrow, I may be looking for a new set of headers soon. And I may have to go custom, but cringe at the thought of how pricey those may be. Wondering if I can haul the car to Kooks in NC and see if they have some that'll fit. (??)
Also considering a pair of Dougs 1.75" mid-length with 3" collectors... These just might fit due to the drop before they turn rearward... They'd have to flow better than the ones on the car now...
Ed, Glad you got better and close to where you wanted to be. Good luck next weekend. I hope the car runs well for you so you can start sorting it out.Got the car dyno'ed this morning, and things are a bit better. With a 1.20" restrictor plate under the carb, swapping the rear gears from 3.55 to 3.73, and leaning out the jets a bit, the dyno said 351rwhp and 359rwtq. A bit better than before, at least more in line with what I wanted. This means I can race at a minimum weight of 3343lbs - with me in the car and no fuel she weighs 3341, without race gear. If the engine is running when I come off track then I should be clear on the weight. At 3343 I could have 370 ft-lbs of rear wheel torque, instead of the 359 I have now. I don't think I'll be spending alot of money chasing that other 11ft-lbs any time soon...
Can't wait to get it on track next weekend...
