and wow, is what i have to say. with the 65 shot it puts you back in the seats, it was a big difference from the 55 shot and i was really surprised. anyone wanting nitrous i say go for it, its great. i have an 86 gxl with full exhaust, cold air box and k&n cone intake, unorthodox racing main pulley, and ZEX nitrous system.

Sounds fun! Hopefully getting my 75 shot this summer. Have fun, and don't blow yourself up!!!!!!!

sinfestboy

isnt a 75 shot alot for a 1.3 litre?

amemiya

we are biulding a 90 n/a with a bridge port and going to start with a 75 shot and work are way up. It's "HER" weakend car. Her other car is a 88 gxl.

rico05

A 75 shot is not too bad if you have enough fuel. I will soon be running a S-AFC and 550cc secondaries. Now if I hadn't gotten that damn ticket, I would have my n20 in a few weeks...

amemiya

that why a wet shot is better you just nned a good fuel pump.

rico05

I will be running a wet shot. I am just extra careful!! Lean + N2O = BOOM!!!!

amemiya

I bet the overlap in the port will waste alot of NOS with a brdge port eh

rico05

More than likely. Just do a mild street port, and you should be fine. I think a bridge port and n20 would not be the best idea.

amemiya

it's either going to be alittle NOS and a bigger port or a little port with a massive exaust port and alot of NOS I like the second one better.

rico05

I still say you will loose a lot of n20 in the "massive exhaust port." If you want to use a 100 jet, and only get the equavilent of a 25 shot, go for it!! Hell, the port will ad like 40 horses anyway right?!?!? Go for it!!!

amemiya

well I will need a big exaust port to let all the NOS out as it decompresses. Like In piston cars they get bigger exaust cams and exuast valves when running lots of NOS. so it all deppens on the amount of NOS we use to what kind port to go with.. man I wish we could do some kinda bench flow on these ports.

HWO

Only if you try to activate it below 4000rpm or there abouts when it is still getting blow-bye above that RPM its all into the chamber

HWO

thats because you have artificial combustion gas basically

you have more gas coming out than you have going in

amemiya

yep I couldn't of said it better myself.

amemiya

no a 75 shot is fine, remember we are rotarys not same vtech. we are small but don't let that full you. are enigines will take NOS like a champ.

vaughnc

just make sure it's WET NOS so you don't go lean
