I've always been an advocate of not coating the outside of exhaust components unless the inside is coated. Keeping the heat in the gas is generally desirable, but keeping it trapped in the metal is not.

The only issue I have is the suspicion that internal coating may not be 100% reliable, and if a piece somehow flakes off and destroys a turbine, you won't be happy. For all that, I would still do it.

There's been plenty of testwork done to show that coating or wrapping exhaust manifolds improves boost threshold (spool) and power. Coating the turbine housing cannot offer as much benefit, because it's too late to save much heat that could help the turbine make more power by that point. But it will certainly reduce engine bay heating, because the turbine housing can be a big piece of metal radiating a lot of heat.

Some result from the new SS2, only had time to do a touch up on my E70 tune and my fuel pump is at its limit. I will need a bigger pump for the E70 to finish off the power run in couple of weeks time. For time been it made 345rwkws at 19psi bleeding down from 22psi. Likely there is another 15KWs gain using a high pressured actuator holding 20psi up top with more fuel. It is currently running the lever mode with a 14psi actuator.

For some reason the lighter material did not alter much in boost response on paper, how ever managed to produce heaps more mid range in comparison to the G2.5 that made similar power output. The difference is very noticeable on road, does not feel laggy at all.

The prediction on pump 98 would be around the 285~300rwkws mark as the capacity of the Type B .82 rear housing is up to the 300rwkws mark.

Congratuations this is mint result man. Why is the torque stupidly high?

Mitch you and I should get this E85 shit happening.

Will my 555 injectors and walbro 255 pump handle E85 up to around 260-270rwkw?

Thats just a guess as to what the SS1PU can pump out when using E85

Don't know enough about the Walbro pumps, but 555 injectors have flowed 320rwkw of E85 before so there's no reason you can't support a safe 300. I have 555s and that's what I'll be shooting for.

My 660's were maxed on E85 with my GTR at 307kw.

Can be done with 555's but without any margin for safety.

Also my drifter runs the walbro 255lph with 301kw on E85 with no issue's to flow. Has 740's tho.

It all depends on the base fuel pressure, If you bump it up the pump has to take the load, if you drop pressure the injectors work harder.

The 1000's I run flow over 1500cc at higher pressure but you would require a damn good fuel system to support high flow at such a high pressure. The 255 Walbro pumps die off at around 80psi and start to make some weird noises, so I decided to lower the base pressure as I hadn't maxed the injectors yet. At least I can raise it up from there if I need more injector. If you were going to load up the fuel pump I would go for the new 416 Walbro as it handles high pressures with much more flow than the 341/342.

As Jez said, leave plenty of overhead in your injectors and pump for safety, you don't want to push either to their limits.

Yep let the saving start

Then I'll sell the 555's an buy something around the 700 mark.

Birds when will yours be going 85?

Might wait to see your results haha

Just get id1000's I think, they idle ok for big injectors and will give you plenty of room for other upgrades down the track

Top feed though, so not plug-in for you 33 guys.

For what it's worth though, my new ID1000's are exactly as good as everyone makes them out to be, they're unbelievable. I've so far only been able to putt around with them, but my car has never idled so well before, the AFR's just sit dead still at 14.7 at idle and all my cold start/hot start issues are gone. My Power Enterprise 650's would bounce around all over the place between 15:1 and over 18:1 (AFR gauge maxed at 18 so couldn't see how much leaner it got). Had quite a rough idle because of it, but now it just purrs. Not sure how much of that is to do with the new Link ecu as well though.

Waste of money given the power level you're shooting for IMO, nonetheless, whatever makes your tuner happy. Gearbox and clutch being put in this week so I guess once that's done I'll book in for a tune. Don't wait for me though, you know E is gonna be awesome :)

Didn't know your gearbox gave way as well.

That sucks big time.

Well I guess it's you and me again buddy let's show these peeps some results

You gonna take it up to Jez for the e85 tune ?

You gonna take it up to Jez for the e85 tune ?

Yeah I will but this time it won't be as rushed.

So might even organise a trailer or something depending on what happens.

Nearly got stuck up there last time because of all the issues that popped up with mine haha.

Stao I'll have to hit you up bud for one of those 14psi actuator I want to be able to track this thing around on 14-15psi then bump it up when the time comes

Road trip then i will tune both cars in a saturday. Then party and check cold start :)

Haha Count me in, hows september sound?

What will you need a trailer for? Just drive it up there as is and do the bigger injectors, drain the 98 from the tank etc when you get up there.

Haha that sounds like Mitch is in and Scotty can be there in case my cooler piping f**ks with us again.

Still got the sweet rusted pipe look happening Jez haha. September works for me if tax is generous

It didn't, it's always had crunchy synchos since I swapped out the Redline crap that the previous owner put in it :down:

Time for a reconditioned unit to go in.

    • Thanks heaps Duncan and GTSBoy. I'll get my old man to sit in the driver's seat and turn it on and off while I test with the meter. Or maybe other way round, depending on whether he remembers where his glasses got to
    • This is the GTR fuel pump. Yellow shows 12V, orange shows earth. The ECU provides the earth to activate the fuel pump relay. The ECU side of teh relay will pull low when the ECU activates. This is the RB20 fuel pump. Almost the same, but a little simpler. You can see I indicated (above) where the 12V line goes down to the RB20 diagram on the overall diagram, whch shows both RB26 and RB20. This is where I show it coming in on the RB20 diagram below. You can see that the dropping resistor is handled differently. When the fuel pump control is not providing earth to the pump, the pump earths through the dropping resistor and thus runs at lower voltage (some is wasted over the resistor) and runs slower. I showed that "not 12V and not quite earth" portion of the wiring in a paler orange. The rest of the wiring that I did not colour on that little section below the pump would be orange when the fuel pump coontroller is providing earth. This drop is handled inside the fuel pump controller in the GTR. Regardless, you can see where 12V is supposed to be, where earth is supposed to be. The key on prime is via the ECU providing the pump for only a few seconds the switching off. You should be able to see that happen.
