E85 Fuel

[rad100]

drunk on e85

stick that just above my exhaust

[Damo_R34]

found a great 98 v e85 comparison:

R32 GTR, standard motor, TO4Z, Powertune twin in-tanks, PFC, 98 vs E85

[dark.sky]

pushing 417kw out of stock 32 GTR motors is where its at.

[rad100]

yeh but its also running more boost

[Brezza]

^ that's exactly what i was going to point out.

its the higher boost that is making more power, and all the E85 is doing is alowing more boost to be run without detonation.

I think my GTR could make near that if it were able to hold 25psi boost, but it seems to peak at 25 then trail off to 20psi

Anyway's, will see what it does on the dyno this weekend

Are you running standard or aftermarket actuator / wastegate springs? Judging by Donnans HPI article, youd see some good results with a stiffer spring!

[ido09s]

Thats a nice boost curve right there. I havent seen one like that in a while

Nice increase over 98 as well but would be keen to see the difference on the same boost

[Madaz]

5psi on 98 wont see those returns either

I've got 14psi actuators from memory? i remember when i had them fitted to the std motor the tuner had to just run wastegate tension because when they were plumbed in boost would hit 18psi.

i've got an Turbosmart E-Boost Street, so it should be able to control boost well enough. might just need some fiddling with the settings to control the wastegates better?

[rad100]

yeh you might need a big can actuator (stiffer)

[Brezza]

shouldn't i just be able to have the wastegates tightened to hold more boost?

i think they're adjustable, they have a threaded rod which looks like you can tighten of loosen to adjust when the wastegate cracks open.

[Damo_R34]

Im sure Sonic Performance would have something!

[rad100]

yeh go speak to jason at mtq.

my external gate hold 20psi flat, put 25psi through it and it bleeds back to 20psi, fitting a stiffer spring will mean boost holds and it bosst will come on earlier too

[Brezza]

seems like i might go for the 19psi actuator next?

hopefully that will let the car crack 500rwhp!

Whats the tank/shelf life of e85 on tap like? As in how long before it starts going off?

[ISC-Performance]

I have 40 litres of Eflex for sale for $20. If anyone is keen shoot me a PM.

[Rolls]

so where in adelaide can we get E85 at the pump?

[Madaz]

Caltex has about 4 locations

United has 2

Tappleys Hill rd and Pooraka

[ECR-033]

Also the United at the airport does it.

I've been told the car would struggle to start in the cold weather, Anyone have any problems with that?

I'm keen to make the switch

[Krishy]

I am just wondering if left in the car for too long will the fuel go bad, anyone??
