Precision Billet Turbos

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

[GTScotT]

2 bar?

if you want to be cheeky try for 3 lol

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

[Roy]

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

[GTScotT]

Also keen to know. Are we talking the Walbro 400?

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.

[Lithium]

Awesome, keen to hear results! That is going to make some serious power...

[usmair]

my guess - 520kw

[Lithium]

Only if it is taken fairly easily, how hard will it be pushed? That turbo I reckon would be good for 600rwkw on this kind of engine if pushed hard.

[Ðemons]

Its all up to jez, what he thinks its cable of I guess. Im sure he will give it a little pushing. I fits all sounding good internally

[Lithium]

35psi - people who don't follow these turbos very closely may get quite a shock. Killer setup, sir.

Which comp and exhaust housings did you decide to go with?

[Ðemons]

Which comp and exhaust housings did you decide to go with?

[Frosty]

I'm surprised no one in here is running Holley pumps or likes....far out perform all these mentioned

[Ryan1200]

1.00 Rear Double check on front Cant remember

Twin scroll? S cover is 4" inlet 2.5" out and H cover is 4" in 3" out.

[Ðemons]

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.
