Running On E85

[Mick_o]

Yeah im lucky ive got the E85 down the road mate so ill net the power i was after HOPEFULLY with the E85...

Shit thats alot of boost for only 243kw has your motor been opened up or is it stock internally?

[89CAL]

stock

She'll be right

Gonna build a motor on the side sometime soon I think. Not gonna go crazy just gonna make sure its not gonna fly apart if I bump it up to 20psi or so

[Mick_o]

Haha just put a cometic head gasket into her mate that will do for 20psi boost

[Jap_star]

Kai has plenty of info for being too small. Better suited to a Rb20 imo. I'd just change turbos, better off long term

[usmair]

what kind of costs are we talking about with this Ethanol sensor + link for e85/98 combo??

i might have a chat to Yavuz after I get my tax refund as well lol

[ido09s]

Link retails for about $2k i think and the sensor is about $400ish. Also need to factor in the possibility of needing bigger injectors unless your car is already on E85

[stÖrmy]

I was talking to a bloke about this today and was thinking about getting the drifter re tuned for e85 but not sure if its worth it. currently only making 240rwhp on the rb20 with vg30 turbo on 15psi, all the usual bolt on mods but internally stock, stock afm and injectors, i am how ever running an intank 040 and an 044 with a surge. what kind of gains can i expect power wise changing from bp98 to e85 with the car exactly how it currently is?

[Mick_o]

Im at a cross roads now ive been told that i will need 1000cc injectors for 270rwkw on E85! couple of lads in here claim to be running 550cc injectors and both are making over 300rwkw on E85

if i went for 1000cc injectors would i have to change my fuel rail too? I was told you use approximately 30% more E85 than 98.......

[ido09s]

30% is pretty right. The tuning style also has a lot to do with what size injectors will be required. Running it lean with less timing will obviously mean you can get away with smaller injectors. Tuning rich with more timing obviously means larger injectors will be required.

They must be running them pretty lean to make 300rwkw on 550's

[89CAL]

1000 seems a bit excessive. I'm hitting 67% duty with my KAI on 550cc injectors just FYI. I'm also running 18psi but. Not sure what boost you were going to use

[Harey]

Anything from the nismo 740cc up will be fine. I am running 800cc and was told I had plenty of injector left at those power levels.

[Mick_o]

If i can run less boost and make more power with the E85 im all for that too i was thinking of around 16-18psi for high boost on the evc and put around on 10psi im hoping the 550cc will get me 270kw.

[Mick_o]

I was told today that my 550's will be ok for 270rwkw on E85 but they will be pretty clos to being at their limit by a nice gentleman from JEM so im gunna take his advice and bolt em in when my turbo comes

[Jap_star]

On 270rwkw with my nismo 555s, there at 70 something percent duty cycle on 98

[ido09s]

damn some people must be tuning lean.... each to their own and everyone has a different philosophy though

Although i realise its a fair whack more power, my 1600's are at 90% at 460odd. That wil change soon though as the ID 1600's have been recalled so its up to 2000cc's

[scotty nm35]

I am fairly sure the 2000's will have similar issues, especially on ethanol, as they are both natural gas injectors from what I'm told. The o-ring isn't rated for petrol (long term) and won't be warranted, especially with e85. If this is true the 1000's may be the only Bosch option.

I also have reservations on the spray pattern with the 2000's as the jellybean plate after the nozzle is designed to desperse the natural gas, not sure how it will work at high liquid fuel flow. Has anyone seen a video of the spray patterns on these injectors?

[high_hp]

I'm doing a upgrade on my car I'm getting 2000 cc injectors .....haltec pro series ecu ..........and I have a.t88 on my gtr but I'm going a bit bigger I was thinking t 51r turbo my car.makes 700 HP at all wheels I want more power :-(

[boostn0199]

My car is not tuned lean with 555 to make 300 kw , its a very safe tune. But yeah in the end comes down to how the specific tuner tunes if he dorsnt believe he can get away with 555 then gota do whats hes confortable with.

[Mick_o]

What kinda turbo and boost are you running mate?

Ive gotta HKS 2835 kai coming and im hoping to push bout 16-18psi down my cars neck.

A guy off here who has the same turbo is only hitting 67% duty cycle on his 550's with 18psi boost

Im running a hypergear tr43i (the really really old model) I guess comparing it to power terms of a garett would be closet to a 3071. Im running 17.5 psi.
