NO2 Limit
Ive got an '85 with 406 c.i. and forged pistons, cast crank, alum. heads, superram. Currently have the NO Systems brand 150 hp TPI "kit"- approx. 10 yrs. old. Have there been any new tricks re. nitrous and the TPI engines? The setup I have injects in front of the plenum. How far in jet size(hp) can I safely increase? Thanks, Jack

I and several others have found this out the expensive way... I finally threw EGT's on #7 and #8 and found them to be running 200 degrees higher than the other cyl's on the bottle... And they were slightly cool in n/a operation... If you're going to do N2O on an SR motor I would suggest direct port.
