For those running meth(map 3) + G5 board...
Couldn't find info on this on any of the forums, so I had to email Terry.
Thought starting a thread would benefit future users with the same question. For those running meth (map 3) + G5 board... What do you guys have your additive set to? What do you guys have the boost failsafe psi set to? Default failsafe is set to 18 psi , which may be too low for anyone running a 60 additive. Terry informed me to set mine to 20 if I run a 55 additive. That would put me at around an 18 psi target, which would give me a 2 psi cushion. Just wondering what additive people are running with the new G5 + meth/E85 mixes or those who run both meth + E85 mixes, since G4 board was really only able to support a 40 additive. Im thinking of running a 55 additive when on meth and doing a 60 additive if i ever run a 30/70 E85/93 mix + meth.... What do y'all think? |

I just had my meth kit installed this past weekend and I have the additive set to 30, for the G4 version, which puts me at 17 psi.

I think a 30 additive puts you at ~16 psi target...

I hit 17psi today after I finally set the JB4 and meth controls up correctly. http://www.n54tech.com/forums/showthread.php?p=159161 According to Coolingmist instructions, I would still need to drive the car some until the system "learns", I guess my driving style or what ever and yes I will post a log.

Yea, RB turbos are several months down the road for me. Have you done a 1/4 mile with your current set up? Also, what kind of exhaust do you have? I didnt spot one in your sig..

I use add. 35... And boost safe at 18. Don't want to push my stock snails too much. I'm happy with 17psi boost. I sent my logs to terry and told
Me I can make add 50 or 60 when I use e85 too.

I run a 40 additive on 93 octane with the failsafe at 19psi.
After seeing some other posts, I'm thinking I could do at least a 50 additive if I up the meth content. Currently I'm using 60/40 meth/water by weight.

I use -20 ww fluid with no additives and add a bottle or two of heet per gallon. Really cheap. 2 bucks for ww fluid and 1 dollar for heet at Walmart. Plus this mixture, will never have to worry flashing or catching fire if leaked
