Can I tune out this bog?
Hi All,
With my new motor, I've been running into a problem bogging off the starting line maybe a third of the time. Cam comes in hard about 4000-4500, converter flashes to 4000 but I can't footbrake it much more than 3200.
When the trans is cool (160-170*) I rarely have a problem but hot lapping a couple rounds trans will get up to 180-190 and I'll start bogging off the line (and usually don't make it to the next round after that ).
I know the best solution is to get a looser converter but I'm wondering if I can tune it out with the carb. I was thinking a bigger pump shot or nozzles might help(?)
Here's the specs:
427++ aluminum head 10.6:1
.630/.630 255/264 @ .050 110LSA 104ICL
Single plane Holley strip dominator
850 Holley dp race (annular) carb (30cc pump, 6.5" power valve)
TH400 trans 4.56:1 gear 3340lb car loaded
Do I have a shot of tuning the bog out or will I just need to deal with the tq converter?
Thanks,
Chris
