I have RB turbos. What's the safest number I can set the jb4 on the methanol settings for the additive?

On pump 93 fuel.

Thank you!!!

I run a 50 adder with 93 pump and 50-50 meth/water. When I add 5gal of e85 I bump it up to a 64 adder. Start at 50 and just make sure you log log log.

But can tell you a 50 additive you should be fine.

Oh wow. I'm at 75 lol. It hits 19psi.. This is with 50/50 e85 93

I'm switch back to just 93 and was curious. I'll try 50. That will give me like 16psi?

What you should do is log your setup to see if all is ok. Of course you have to make sure the fueling is there.more additive the more boost you run. But with 50/50 E85 and meth sounds like you are def safe.but do see people run 75 additive with no problems. Just do some logs to see what they look like. When running higher mix of E85 a inline pump would be recommended. Just do some logs to see if anything is out of normal.RB TURBOS at 19 psi if fine by the way.

Thank you.

But 19 psi isn't safe for just 50/50 meth and pump 93..

I put it down to 50 on the jb4 for additive and it feels so slow
