versiitality of set up

wideopen231:
Base combo performance numbers and what did you pickup with 30% load,other than big grin?

msundstrom:
.3 seconds approximately and 40% an additional .2

Spud Miller:

 The crew and I have discussed a few times what my car would do now on straight methanol instead of straight nitro. Lower compression ratio, low gear, rear gears, tight converter...it's heavier now too. It would be a quite a bit slower than back when I started with a typical methanol setup. I started in the 8.60 range. The consensus is we'd be doing 9.30's or worse vs. our typical 6.80's on 100%.

 Hopefully, we will find out when my daughter starts driving it in 5 or 6 years. That's exactly how we plan to start out...0% and work our way up again.

What would be the highest percentage with setup above.Maybe changing converter to makeup for eixtra torque.Figure bottom end is about as strong as going to get.Already running grp aluminum rods,KB billet crank,Heck same stuff TF ran for long time.Bjgget limit would be pump flow and shallow pockets.LOL

dreracecar:
Back in the beginning of Nost A/F the rule was only the 80a (6.5) could be used for both types of engines either injected nitro or blown alc.  It was felt by the rules makers that this would even out the cars for close racing around the 6.90/7.00 range.  JC Constance could not get below 7.20 without back-sideing all 8 pistons running injected nitro with the small pump--- AND Gene Adams was doing the tuning
