Modlist- turboxs mbc set to 20 psi, Intake, TB exaust, HKS 272/272 cams, arp head studs, greddy upper/lower ic piping, greddy r-spl intercooler, walbro 255,ats carbon carbon clutch. Question is would a 50-75 shot be alright on stock internals? I have used a 35 for a while with no problems.

 

i want to use NOS for my evo. but seems like nobody is using NOS here,

 

another question i have that i forgot to put in my post is would the alcohol injection help out for more juice?

 

yeah i dont hear anything about nos here

 

50 shot will be fine make sure its a wet and not sure on the alki ?

 

I have Used a 50 shot for about a year... no problem....just need the right amount of fuel...and def. a wet kit...

 

did you do a compression check after using it for a while? if so how was it compared to before the n20

 

my compression is fine.....but i did do a head gasket andd ARP head studs before N2o

 

Anyone doing a 75 on stock internals?

 

If your going to run a 75hp system make sure its a wet not a dry. I would reccommend you set up a secondary/independant fuel system for nos only... so you don't draw too much fuel away from the stock one and alcohol injection would help if your going to go through the trouble to install one.

 

secondary fuel system just for a 75 shot? It is a wet kit.

 

also when is tuning really necessary? with say a piggy back or full stand alone or would just an afc help enough?

 

you do not tune a nitrous system with a piggyback. you want to run a wet kit and tune the AF ratio with the nitrous jetting. if you screw around with your AFC settings when the ntrious is on, they are now not correct when the nitrous is off.

 

and when would u say tuning is necessary?

 

After you install the wet nitrous kit and run it for the first time, you should be logging the air/fuel ratio and adjusting the jets in the kit accordingly. Also remember that bottle pressure has a major effect on the kit's jetting and that needs to be held constant with a bottle heater and purge for the best results.
