Depends if he is running E85 or not, my 6262 went 450kw on a hubber running E85 with baby cams. When it was making that power top end it was only running 19psi.

I'm sure on 98 you should go close to 400rwkw on 20-22psi with a 6262

Got a new fuel pump (Magnafuel) that arrived today... Getting it all ready tonight and hopefully back on the dyno tomorrow.

See how it goes on 1.6bar throughout the rev range, hell if I get cheeky might go 2bar and go for 500kw :)

Do it. You won't do it. :P

myengines back in the car, 6266 is bolted on and custom oil/return lines made

just waiting to finish the dump and intercooler pipe then its turn key, wont be atleast afew weeks till its tuned to post results (on e85)

simon R32 keen as to see your results mate, whats the flow difference between the walbro e85 and ur new pump?

Walbro 355L/hr at 70psi and the Magnafuel Protuner 625 402L/hr

Walbro is so much better... Smaller, lighter, quieter and cheaper but can't be used externally so I had to look at other options.

Fired up the Magnafuel tonight, it's pretty loud (would be louder than a pair of 044s) but it should do the business

Did you replace the Walbro due to outright flow or lack of stability in pressure...or other reason ?

I had a Walbro in the Green car, was perfect. The GTR had a surge tank and Bosch 044, it ran out of flow so I needed to go either twin 044's or a big single pump, hense the Magnafuel getting the tick.

Hey guys, Nearly D Day for my GTR to jump on the rollers With the 6766 CEA & e85. Be Interesting to see what Jez can do with the beast Dont think hes tuned something this big as yet Maybe, except for the T88 Top Secret GTR.

I bet Alot of you guys are wondering what the 6766 can do on a Built RB26, Well I havent seen what they can do as yet anyways. shes got big cams in her so will be interesting 280 11.5mm Lift Just hope the engine likes the boost that these turbos produce.

Twin scroll ryan 4inch inlet & 3inch out from memory. Has 3.5 inch exhaust but not that thats going to matter its coming straight out of gate so should sound the goods lol.

What comp ratio is the engine? Any tricky headwork?

    • So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?
    • I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.
    • Stop looking at the garage floor, and turn the radio up a bit louder if there's any strange noises...
    • No. Turbo shuffle and surge/flutter are not the same thing. Specifically, on a GTR, turbo shuffle has a definite meaning. On a GTR, the twin turbos are assumed to be the same thing and to operate the same way, exactly. In reality, they do not. Their exhaust sides are fed and exhaust a little differently, to each other. Their inlet sides are fed and exhausted a little differently, to each other. Consequently, when they are "working" they are often at slightly different points on the compressor map compared to each other. What this means, particularly when coming on boost, is that one of them will spool up and start producing extra flow compared to the other, which will put back pressure on that other compressor, which will push the operating point on that other compressor up (vertically). This will generally result in it bumping up against the surge line on the map, but even if it doesn't, it upsets the compressor and you get this surging shuffle back and forth between them That is "turbo shuffle" on a GTR. It is related to other flutter effects heard on other turbo systems, but it is a particular feature of the somewhat crappy outlet piping arrangement on RB26s. There are plenty of mods that have been attempted with varying levels of success. People have ground out and/or welded more material into the twin turbo pipe to try to prevent it. Extending the divider inside it works, removing material doesn't. There are aftermarket replacement twin turbo pipes available, and these exist pretty mush purely because of this shuffle problem.
    • You can temporarily* use lock collars to keep it in place until you can do the bushes, back the nuts off, slide them in, snug back up. *temporarily is often for ever
