An intercooler cools the air before it gets to the injector at all

As to whether E85 can simply ignore heat soak, nfi. It does a lot of wonderful other things so why not try!

[scotty nm35]

Intake and exhaust temps won't really matter anymore, unless you want to run 50psi plus. I cut the Stagea one in half and it still works well.

I'm running the stock evo cooler at 300kw. A larger cooler is just a bigger heat sink at the end of the day. Perhaps a simple water sprayer like the evo's run would sort you out?

A good bar and plate cooler is only a couple of hundred.

Hrm, yeah I think intake temps will reach about 80c + with more boost from memory on some posts I've seen.

I wonder what power gain you could get from doing just a pulley + injector/e85 change.. in theory you'd make the 450ish rwkw mark like the rest of the guys but the intercooler would keep it consistent and reliable I guess.

The thing is there is no stock cooler & it's supercharged so that water spray idea wouldn't work - so the cooler has to be a water to air type that sits inbetween the supercharger lid and charger, enclosed air tight so water lines need to find their way into the 'sandwich plate / core' and gets pumped back to a much larger front radiator (these kits are like ~5k)

Anyway it's not that important still makes good power, but you always want more

Surely if this idea was valid people would be doing it to save themselves 5k

I was impressed at how well the FT86 was going at PI, with just an e85 tune. (no turbo) High comp motors love it, and that's essentially what you have with a supercharger.

The main issue you have is you will be det limited, which is a non issue running ethanol. The extra torque is crazy, even if you don't push more timing into it.

[Birds]

Do I really have to state again that my E85 tune was done in summer.

This is very different to tuning in winter and a winter tune vice versa simply won't bode as well on scorching days. People having E85 starting troubles from both of the tuners who shall not be named suggests there is validity to my point. When ambient temperature has a huge effect on engine performance and you have a static tune that doesn't auto correct for variables...what makes anyone think there is one optimal tune for all conditions? It's always going to be a compromise.

The main reason I haven't tried it is because of it being my daily, often going for dirtbike trips in the middle of nowhere and need dat 98 availability

Maybe one day I'll give it a go..

No compromise if the mapping is complete, and you have a decent array of sensors. With modern ecu's running intake air temp and Wo2 correction there should be no issues if the tuner has done his job.

Upgrading to the Haltech Elite in the evo soon, with the timing map done the rest will self tune. That should offset the cost of the ecu nicely and hopefully save me fuel down the track, let alone not having to pay for tuning anymore.

Flex tuning is probably the answer if you don't want to carry a jerry or two. That way you can run any mix of the two you like.

E85's big card is its 107 octane rating that is more resilient to detonation and allows you to advance timing beyond what you could achieve with 98 all things equal. With this in mind, theoretically you will see a significant midrange power increase for any forced induction vehicle regardless of its intercooler setup or lack of. I see no reason it can't substitute the detonation prevention that a intercooler provides in cooling the air and therefore the mixture pre-combustion, as ultimately it's the fuel that reacts to the hot air and you're changing the fuel here.

E85 still suffers from its myths and people being scared to try something new that they've heard unfounded bad about - there's no reason XR6 turbos can't benefit from them and they do, there are plenty of them running it, just not as many as Skylines and Evos. It's just that the Jap import community jumped on E85 before the Aussie car enthusiasts did and when yours peers do mods you're more likely to do them than other people will.

But that's not a static tune nor a Power FC, which is the issue here. Ultimately people like myself have to get a winter and summer tune and even that is a compromise...else upgrade to an ECU that can auto correct or auto tune.

That sounds like a good yet expensive idea

Actually yeah there is a fair few xr6ts going about these days with it, I think they respond a bit better than the miami engine, that and people tend to mod the shit out of them a little more than the v8 boys. (much like jdm cars I guess, when you're modding to push like 2x the power or more out of them.)

Where you going for dirt bike trips that isn't a 400km round trip?

I try and warn people the PFC is a 20 year old piece of dinosaur tech, and it's worth $20 in the scheme of things. There have been better options for many years but everyone still gags over them.

The flex sensor is only $50, but the ecu to control it is expensive. (although at least you can then access it yourself rather than have to pay for the same tuner to access it like the Xcal pos.)

What sort of power/torque increases have the 86 people seen from it?

Sounds like you need a better tuner bro... perhaps someone with a HubDyno for dem extra accuracies
