Guilt-toy Now Running On E85 !

[Beer Baron]

holy crap PJ!!! that is awesome mate. love that it's not super loud either. would love to see the specs? even a basic outline? great stuff mate.

[Lithium]

Whoa.... What turbo now?

[WARLORD]

pj wtf was that a nuclear injection.

[PJ.]

Thanks guys

Sure I can give you basics

It's an SR20VE+T now, big custom cams, sleeved / forged bottom end, modded Precision turbo on 6boost manifold, ported head, oversized valves etc, Bosch 2000cc injectors, custom plenum, Plazmaman throttle body.

[Beer Baron]

sounds wicked. there is some cool stuff happening around the place with the SR VET heads going on to SR20s. but your thing is out of this world. I'd like to come check it out one day soon.

Thats awesome, its a PT6765 I'm guessing? The Precision and the FP-HTA billet turbos are wicked pieces of kit, good to see them catching on down this part of the world. I am hoping that soon I'll be able to report some results for a built RB25 running a PT6765 on E85... that should be quite interesting.

cheers mate, allways keen to try new things!

Yes i used to get 380 to 450km's to a tank with BP98 depending how i drove it. I came up with a magical number in my head when making up the map in datalogit on my pc at home which was spot on, and its no way near double then what it was, but i will say it is more then 25% consumption.

My gtr uses bout 20 litres per 100 ks I did a trip from.Brisbane to.tweed on.the weekend and.went through a tank in 180 km mind u its a very very heavaly modified engine

Finally joined the E85 club! RB25 Neo with super responsive turbo making 242rwkw on 98 and 279rwkw on E85! Very happy

Havent tried cold start yet but my idle is smoother than on 98! Thanks Trent from Status Tuning and Tao from Hypergear turbos!

Hi guys,

I just had my car run on a dyno on the weekend, it pulled 353rwkw @ 24.5psi

the AFR's were dead flat on 11:1

boost held strong to redline, only droping maybe 1.5-2psi from peak.

question is, is 11:1 AFR too rich for E85? i dont think there is much advance timing in the tune, maybe 3-5 degrees over PULP

[Brezza]

sorry

double post

[Beer Baron]

what turbo's etc?

[Beer Baron]

what turbo's are you using? any other details?

[Brezza]

turbo's -5's

exhaust 3in full system incl 3in decat

nismo AFM's

std airbox

K&N air filter

1000cc injectors

Nistune ECU

twin walbro in tank fuel pumps

ARC 70mm intercooler

silicone I/C piping

std cams (recond when engine rebuilt)

forged bottom end

Mines dump pipes

std manifolds

that's pretty much it

[Harey]

Your exhaust is on the small side. Rough guide on here is 3" for 300rwkw, 3.5" for 350rwkw and 4" for 400rwkw+.

What power did it make on 98?

[Brezza]

It made 318 @ 21.5psi

and that was on the same dyno

[Harey]

That is very low power for -5s on 98 fuel. I would fix whatever the issue is holding that back. Should be able to make around 350rwkw on 98 first. 318 is -7 or -9 power. Whatever restriction you have may be holding back your E85 results in a more significant way.

[Beer Baron]

honestly in my experience it's in the ball park. having seen dozens of cars with -5s most often they make between 310 and 340kw at 20-22psi. 353kw on E85 is not bad. perhaps a little low but every car and every dyno is so different as long as it's performing it's not worth worrying about.

11:8 to 12 AFR is the sweet/safe spot. Leaning it out a bit will net you some gains.
