I saw on NRE, or nelson racing engines and I have heard of it before with v8 guys. Anyway, NRE run's 2 fuel tank's and has a tank with race gas and one tank with pump fuel and it's boost referenced. Has anyone done this on a 4g63 car? I was thinking it would be perfect for guys who didn't have super easy access to the e85 and could just run a larger oem fuel tank for pump and then a boost referenced smaller e85 tank. Yes I have researched this somewhat before on another forum and the problem was that we run a return with the fuel and where would that go?


Any tuners/builders are especially welcome to post!

 

Vishnu did it for a TV show back in the day.

 

Tephra switch mod?

 

I believe it has been done....although Race gas (at least around my parts) is very pricey....so not sure if it would be very feasible for DD use.

 

Yeah, the best fuel in the world for a second tank - methanol.

 

very easy to develop w/ a lil ingenuity. just can be costly.

2ndary fuel tank + all lines/fittings + pump + 2ndary fuel rail/injector set + hobbswitch...


or...direct port meth.
