Well I am thinking about picking up a 2.9 and 42# injectors. I have a Pacesetter Header laying around in my garage waiting to be installed. I currently only have a K&N intake on my car. I was wondering what tune should I run, and if it would be beneficial to run E85 or 110 on my car.
Any suggestions? thanks!

 

if youre gonna run e-85 youre gonna need bigger injectors. 79's or 80's at least.

 

oh really? sht. haha Well i am just trying to plan everything out before I do it.
I just have a friend who might run E85 on his HPF M3 and was wondering if i wanted a half drum of it lol.

 

Just my .02 but race fuel is expensive. 110 I mean. I know E-85 will take bigger injectors but why not just put 60's (or 80's for future mods) and run a 2.7

 

i am getting the 42s and the 2.9 for a steal. and i have a friend who regularly gets 110 and Meth shipped to him

 

oh well that makes sense then. Just saying I know 110 is like upwards of $6 a gallon here if not more.

 

With e85 you will need the 80's. 2.9 and a tune and you will feel a bit more power. I have a bunch more than that and run 93 and nothing less, not sure if you will gain anything with a 110 mix.

 

well more octane is more octane. If one wouldn't gain anything from 89 to 93 then why are there different grades? Fact is you do gain by going to a higher octane. However, if you are not building a race only vehicle then why pay 2 bucks more a gallon. I guess that is my point.

 

Might want to consider 60s instead of 42s if your runnin 2.9
I'm running a 2.85 and if Im not careful I get REALLY close
to maxing mine out. Just a thought. Later this year I hope
to get 60s myself.

 

like i stated before i am getting the 2.9 and the 42s for super cheap and i cant pass it up

 

well if you are set on the 42's then you gotta run 93 with a 2.9. any higher octane and you will lean out.

 

Someone knows what i'm talking about. Just cause you use 110 doesn't mean you will automatically bennefit from it. Too much and you can burn parts up when you're not built for it.
