I would presume the result of this thread was: Headstuds, -9's, cam gears, injectors, fuel system, E85 ecu and a tune?

It wont be that easy :thumbsup:

what makes you say that?

as long as you have fuel setup sorted and you have appropriate boost control there shouldnt b too much dramas

ppl say you get 15-20% increase in power from e85

so a 330kw GTR should crack 375kw on e85... theoritically atleast

What makes Paul say that is no doubt that he makes 400kw, and knows that theory can be a long way from reality.

By all means try your theory, go get some ID2000's, a large fuel pump or two 044's, whatever EBC you like, -9's and see how you go at 24psi. Let us know how you go

Generally it seems to only be around 20-30rwkw though in terms of gains. I think 350-360rwkw would be more realistic.

What would be more interesting though... How much earlier would they come on?

Given everyone seems to gain a few hundred RPM response. Getting -9s on even sooner would really be quite something.

Whilst 200-300rpm might not sound like a lot, if its coming up in/out of throttle faster too... It would be awesome!

Yeh I'm gonna.. as soon as caltex get some elfex around my area

Would b interesting with -9s

ID1000s won't b enough?

I suppose it depends on who tunes it.

Im running ID 2000's (2225cc) and at 400rwkw im using a Duty cycle of about 63% IIRC (AFR's are about 11.6:1 Petrol corrected according to my wideband (Roughly .80 Lambda)). If you calculate that back thats just on 1400 CC worth of injector. Thats on a 2.8 with GT RS's at 1.75 bar. Its a little low as my exhuast was choking it like a whore.

That's what you do notice. That half to full throttle instant response. Well I use 'instant' very loosly with GT RS's. It was alot better with E85! pinch.gif

What area are you in? Its at a few places now, so if the skyline isn't your daily driver you'll be fine.

You're talking a 2.6L right? Mine maxed 1000's at 403rwkw but its an rb30 - capacity makes a difference.

Yeah this is an interesting point.

My throttle response hasn't got any better or worse since before and after the E85 swap. I took the time to make sure it was how I wanted it while it was on pump though.

Edit; I dont mean turbo lag.

I see that stated a lot but can't understand why! Can you explain why would engine capacity makes a difference?

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
