I didnt get to test out the nitrous dave dry spray ring this weekend at the track because of rain. Rain Pawns.

my N20 starts spraying at 2800 RPM and shuts off at 6300 RPM.

75 shot on a 10lb bottle ought to last 7-8 1/4 mile runs

Why is nitrous expressed in "shots"? Im sure thats the most ignorant question of the day, but Ive always wondered that.

I am running a single pattern camshaft (check sig) which really is a slight reverse split @ 220/219 .633''/.631''.

Also note, I'm using Thorley 'tri-****' headers and full 2.5'' exhaust.

Soooo, what are we looking at exactly... A single pattern camshaft can support upwards of 400rwhp thru full exhaust. What will adding exhaust lobe do? Boost top end HP, aka more MPH. Taking exhaust lobe away will do what? Make more torque? Heck, I'm not even loosing MPH yet on a SINGLE PATTERN cam ya know.

Just thinking is all....

I know what your saying, I think more exhaust lobe would help with your mph and pull the hp out some. But if you dont have the intake to support it then its a waste. I like the single pattern cams thats why I have one. Im the only NA 5.3 with an ECSB z71 that has run a 13sec 1/4 as far as I know.

I bet you could pick up another .2 with a cutout, I gained a 1/10 in the 1/8 and my exhaust is completely open including the muffler.

Why dont you like the thorleys?
