bump???

 

You need about 30% more fuel ROUGHLY, so you can figure out what you need.

 

I just want to know, how the do you pronounce your screen name?

If you want people's opinions on sizing, you should should probably give a little more info.

 

LOL my sn? Its just the word turbo with 94 eg inbetween the letters...my setup is stock b20 with sc34 log mani 255 walbro and 580 injectors...

 

As was previously stated, you need about 30% more fuel than a conventional gasoline setup. If you need help picking the correct size injector, just use 6cc of injector per whp. On E85, you need 7.8cc per whp.

 

3000cc injectors for 500whp... ? You forgot the part about dividing by the number of cylinders....can't forget that.

 

also what plugs would I run with E85

 

I'm runnin standard NGK's....number 6's

I thought that portion of it was a given...you need 3000cc of injector for the whole engine, then you divide by the number of cylinders...in our case, 4

 

There's no such thing as a given on these forums...hahahaha...you know that. If there were things that were a given just think how many less threads there'd be about ebay manifolds....lol.

 

HAHA can u give me the exact part number on those plugs??? Thanks

 

Dont you need to upgrade all your fuel lines also as E85 has way more corrosive properties then regular petrol.
