0-45 Best 5.70-60 Best 7.8 or 7.9

I timed these with my cell phone, I press the start button when I hit the gas, and then again when I reached the speed...

i forgot to include that im running single cam pistons( flat top ) which brought up my compression to about 230 pretty solid with the 248 cams on both side! well i've been spraying on my KA for about a good 7 months and i do have to say that the KA can hold up the nitrious very well! i'll keep you guys posted on the times...

Well NOS also for some reason loves higher compression and with the SOHC pistons in that DE you are running between 10 to 11:1 compression ratio heh.

well, nitrous oxide does work well with high compression for a few reasons. a major reason is it is a much cooler intake charge which is better for the high compression motor to compress. a normal high comp motor usually has to worry about knock or running higher octanes to accomodate the tendency to detonate. with nitrous youre going to be adding extra fuel which is good, and a cooler intake charge which is good. however, like all thermal devices the increased power produced will also output more heat, which is always the enemy of efficiency....

and i guess, "blowing the welds on the intake manifold."

and i guess without flycutting your pistons, you have 89 style pistons, so compression is around 11.2-.3 without any larger headgasket or extra work. jsut to clairfy.

the only reason i said anything is because thats what i wanted to be doing by next summer. high compression will be done in the winter, but i wanted to have a 75 shot. i too am curious to see how you're holding up and what you think of a slightly bigger shot

sorry josh for the mistake! but next weekend imma be upgrading my jets so imma be spraying at least a good 85 shots of nitrious... heres a thought if you do plan going into the single cam pistons instead of having the 1 exhaust and 1 intake or 2 exhaust cams try using 2 INTAKE CAMS and you'll trip out on high the compression on your motor will go! i will let you guys know on how the motor held with the bigger shot of nitrious
