if its the old one it will not flow past 430 hp atw, im still waiting for the new one that will flow well into 500hp as he has designed it but has no made any for the public.
or i have found a hpi copy made from 321 s/s with 42.7 i.d.....thats why i want to know the i.d of the stock one be for i flow test one as i have a flow test of a stock manifold and i want to compare.
closer to the injector so the pressure is always in the line or you will get a delay.i run two but thats just me one at the tank and one at the injector
a check valve befor tthe nozzle is a good idea.
these guys make the best nozzle ive used 2 different ones the check valves are good to. : http://www.alcohol-injection.com/
best tank ive seen and strongest pumps: www.coolingmist.com/
ive dealt with them and had good dealings with them.
this is based on my opinion and my use of the products great with nos,i use googee methanol 50/50 with distilled water.ive had no detonation at all. car has not been tuned with it on a dyno but works well with 3-5 psi more boost.i only got it for my nos setup but its worked well with every day running so far.
then pics of some of he set up are here http://www.skylinesaustralia.com/forums/Mo...html&st=160
this is a post i did a while ago http://www.skylinesaustralia.com/forums/Wa...on-t281683.html
hks 256/264 h/d valve springs revs 8500 rpm all day and ive done 30,000 km on it with 100 passes at the drags its a good combo.
jim at crd tuned the car he wanted to go past the 8500 rpm cos it was still was making power but i dint want to.
