Nitrous oxide and exhaust piping diameter
Greetings all,
I know Nitrous is not the FI of choice around here, but just for a moment lets pretend it is
.
When people talk about a turbo car, the general opinion is run the biggest exhaust that you ears can stand. When building a car for nitrous would the same hold true?
My two previous Honda's ran a small shot of nitrous (50 from a N.O.S wet kit) I ran DC sports 2 peice 4-2-1 header on both the sohc with a 2.25 B pipe to a magna flow muffler. the B16 powered car ran DC 4-2-1 to a 2.25" B pipe to a thermal research muffler on the other. My thinking on this was I'm off the bottle more than I'm on.
On my current project (integra GSR) I plan on being on the bottle more than off. I plan on a 75 HP shot from a nitrous express wet kit. I also plan to upgrade the fuel pump, possibly fuel rail and injectors and plan on running some race gas. Would I be better off running a larger diameter exhaust than on my two previous street cars?
Plan on doing some weekend drag racing. Not looking to win just wanna go fast and have some fun.

I run 2.5" straight piping. Hatch with stock H22 and a 50 shot. I'd run 2.5" inch piping collector-back.

No. You want to maintain the appropriate balance between flow and exhaust gas velocity just like a NA application.
