Fastest GTR and highest WHP GTR in Canada ?

[LIGHTSPD]

Sorry after thought and it is late might want to check and see if the Fuel pump voltage regulator is switching to full voltage under load.

The pumps are wired directly to the battery via twin relays. They are showing between 13.5 to 14.5 volts (was one of the first things I checked when I first bought the car). I'm going to use the HICAS (currently stock) lines for fuel lines (feed and return) and will split the feed to both ends of the rail (GReddy) and move the FPR (also GReddy) to the center. One of the things I have learned the hard way over the years is to make that return as big as possible for nice stable pressure and to keep an A1000 pump nice and cool to make it last.

I realise the ways of calculating the HP at the upper 70's of duty cycle are pointing to more power than I'm figuring but I like to be conservative. I will admit though, she pulls REALLY EFFING hard at 1.4bar, much harder than I though it would with only a .2 bump in boost. Gotta love the T-88, so much volume at a given pressure, I blew away a Viper with only .9bar .

On a rolling start lol.

No one running e85? I think I'm gonna experiment with that fuel this spring. Last year I made 475whp on a chassis dyno with gt2860r-5, my turbos have since been sold (built bottom and built head). Next year is a billet turbo with some e85 and maybe some water injection.

Some have tuned big power RB26's on E85. I actually bought a set of 1000cc/min precision injectors from a guy who was moving up to 1600's to get the flow he needed...

where in canada does e85 exist?

Anywhere you ship it to friend.

We can bring it in by the barrel real impractical for Canada limits your cruise range good for track only car but so many things need to be changed to make it work proper.

If you want to run E85, make sure your fuel system is alcohol compatible, and keep in mind that you would need to re-tune to get the most out of it. My Z32 Nismo injectors die at the sight of ethanol (even 20% blend)...not sure what GT-R injectors (if any) are affected, or if any other fuel system components on the GT-R are not alcohol compatible (i.e. fuel pump seals or FPR diaphram). E85 has a lot less energy potential/volume than regular gas, so you will loose power unless you really tune to take advantage of it's detonation resistance.

Water/Meth injection is another way to go that avoids compatability issues on older fuel systems, plus adds other benefits like cooling and cleaning while raising octane. It will typically let you run another 6-8PSI of boost over pump gas, but again, re-tune required to take full advantage as it will cause you to run too rich. Methanol is definately way more widely available in Canada than E85 (any home hardware store, auto parts store or Canadian Tire will have Methanol).

I noticed a few questions on target AFRs...so I contracted some verbal diarrhea, and threw together a bit of a tuning guide. Feel free to review/correct/contribute!

So SR20GT30 is the only Canadian 9 second GTR... 9.74 @141

Billet RB26 block for serious hp -

The billet 4cyl blocks are used on engines producing over 1000awhp -

I'm working on an rb30 and a new efr8374.

Also, bump for pics and updates!!!

[ChuckNorris]

woow that high 9 sec GTR is just pure sex! thats sooo sick man!

I've got the forged rb30 at speeddm's garage, dry sump kit at customs, 4wd adapter/block brace is about to be ordered when hi octane return my email, and the turbo isn't available to the public yet.
