The 5:27 was @ 1978 static alt. I for got to check corrected this at Barona Ca. I would like to have some bank to play with when i run it. I had run a 8:04 in Las Vegas @ 162 on a small 1225 motor. I think corrected in LV that day was in 3800 foot level. I now have a 1340 hauling the 250 rider< me . bike weight is 400 even with the whole package being 650. give or take a cheese burger.Maybe a mid to high .20
Your 1/8 ET and MPH are strong considering that short time... Nitrous TG bikes usually dont have to even run 5.20 to run 8.20.
