Maximum Boost

Recommended Posts

Hello Mate, I noticed your sig states 103 race fuel, is this what you are running at 1.5Bar. I am currently running a maximum of 1.4bar on 650cc with Emanage and my Dyno Graph shows my fuelling as spot on.

 

I was going to increase the boost a bit and use the water injection to compensate so I dont get any det but I was unsure if this is safe on 98octane.

 

 

 

Supraforums had a thread stating safe boost pressures on certain grades of fuel but unfortunately all there numbers seem to be different and they are quoting RON etc.

 

Only ever use 103 fuel. Also run meth/water inj (70/30), large ducted fmic, external induction feed.

All these measures help prevent det, but ultimately, if the fueling/timing isn't mapped correctly at these boost levels, it will burn something very quickly.

Thanks Guys - Ian are you still taking your Laptop to JAE? If possible and you have the time I would like you to download my current Emanage map. We have previously spoke about me bringing my Supra to you for tweaking?

 

Are you there on Sunday?

 

I'm there on sunday :) And yes, the laptop will be as well :thumbs:

 

-Ian
