COS5 is a Custom Operating System from EFIlive that allows you to use the stock PCM to control NO2 and add fuel and remover timing while spraying.

 

I was told i could go a lil lower with it being a small shot..








Whats the issue with spraying at lower RPMs?

 

If your piston speed is not enough it will likely detonate. Also I have seen some manifolds blow apart, probably from a backfire?

 

That's another thing with dry vs wet, your not to likely to have a nitrous back fire if there is no gas in the intake.

 

this is why you with a dry and just up grade injectors.plus if you are only spraying @ low rpms then you will not need bigger inj. you will not have build enough boost at the lower rpm to max out the inj.

 

SO,, since i like being difficult, i could run a dry shot out of the hole then switch to a wet shot once i get on out a lil?

Yea cause my IDCs are 84% at 6000rpms.. and i shift at 5600,. Just wanted to check the IDC one day to see what they were at.

Looks like ill be doin a lil testing.

Thanks guys.... anything else?

 

 

haha... you must not be doin too much Randy?

 

Randy Give me a call I have a swabbing company that is looking for a good welder. They are in Laurel.

Nonnie call me I think a 2 step would help you build a little boost I think we can rig you something up or a transbrake.

 

In the past I've sprayed a 125 @ 2000 rpm on a stock bottom end 350...but I don't see taking the chance on a more expensive setup. 2800-3000 would be my choice to be safe fwiw.
