Oh absolutely. This was over 10 years ago when they first went to the push systems and then went away from them. My friend Jason (he bought some parts from you, he's building the LS2 RX7) and I worked on a pro-mod car right out of high school in 93. The nitrous guys were going fast when they kept them together, but they didn't have the know-how to keep them together. Today I'm sure its different. Back then a pro-mod car was making about 1800 with everything thrown at it, now you can do that with a small block street car

its keeps bottle pressure up and gives u the same amount of juice going threw the n2o noids..yes u are right that it will rich the engine on the top end but only because the engine aint getting the same shot size as in the first half it was getting.

Which is exactly what I said happened. Bottle pressure gets low during a pass, mixture richens up. Bottle pressure doesn't get low during a pass, mixture stays leaner, but at 8500 RPM's its a bit too lean KABOOM.

i was saying that u dont get it..them cars dont go lean on the top end just like al said it was them just half ass tuning back in the days..them boys tune and dyno them engines all the time trust me..gene fulton is a rich man from them eating engines up.them tunes are for upper rpms not lower rpms..u ever sit on the line lately at the strip while a pro-mod 4 stage monster runs..they are rich at the hit most of the time.

also they only pop them when they put them on the ragid edge and most of the time that is when there in the highest rpms with all the kits going and the engine on kill..them big cubic inche engines are at there limits..the 738ci engines bores actualy gos oval during a pass some what.

as for the early years of pro-mod the n2o cars stamped the blower boys..after awhile the blower guys figured there shit out..then they let the high helax blowers run and now the blower guys stomp the n2o guys..shannon jenkins has already said a year and a half ago that the n2o guys are done..they got nothing more left in them engines there at there max.

also they run them engines so hard on missed shift or your late on a shift boom engine gone ask jenkins he will tell u..
