If you build a cam for a Nitrous car it would have more lift for the exhaust valves, right? There are other things you could do to accomplish the same.

Don't most of guys run shorty headers on your cars? Would equal length tubes be better? Would bumping the diameter of the tubes assist a Nitrous car? You need back pressure for an exhaust system. But if the goal for a nitrous car is to allow my exhaust flow wouldn't bumping the diameter and going to equal length accomplish this? Yes, I am a

 

you really dont need backpressure from what ive read

 

not so much more lift as more duration...
and really.. on a nitrous cam, the key is making it breathe, but reducing the overlap in such a way that the nitrous charge doesnt get blown out the exhaust.
IMO, unless you're going for ultra reliable/low maintance, run as much lift as you can sanely do.. lol. (btw, thats a gross generaization.. theres alot more to cams then just lift and duration)


most serious people run longtubes. shortys are for the lowered car guys that just want a lil more, but dont mind exchanging power for a bit more ground clearance...
99% of the NA or nitrous cars here that are fast, run longtubes.



ideally, a tuned equal length header would be better... but really you're stuck to whats off the shelf... and they're CLOSE to equal lengths, and in the right range for the average motor... not ideal, but they're also 1/4 the cost of 'cheap' custom headers.



how much spray? small? no.
but it doesnt matter anyway... you're limited on your selection of longtubes unless you go custom.
go custom, and you can size it to the motor.. but you probably dont need anything huge unless you're trying to push air from a 800hp monster.. lol.


NO! you do not.
now pressure waves, tuned/timed to come back to increase scavaging or reduce overlap effects are nice... but backpressure is never good.
dont worry, you're not the only one confused with the diff between sizing stuff/tuning and backpressure assumpsions.


its no diffrent then tuning the exhaust for any other motor.. at an RPM range, there is an ideal length.. for the volume of air moved, there is an ideal tube size.. ect.

 

overlap not lift...the exhaust valve needs to be open longer

 

you mean duration.... not overlap.
