Tsukuba Race Prep (all Finished, Some Vids & Pics ) !

[SRS13]

Good luck with it - if the N1's enabled you to run 137mph then these should give you enough power! 1:02 at Wakefield will be blisteringly quick on a short tight track.

How much boost you going to run and what power are you aiming for with this set-up?

Great to see you guys are going all out and not doing it half arsed!

[Snowman]

The -5's are great Russ (Im running them now). I saw a GT-R make 440rwkw's @19psi on 100 fuel the other day with these so they have great potential.

[giant]

YEAH 1:02 is the goal whether we can achieve it is, another question.

looking for power around the 450 - 470 awkw, hopefully with power all the way through to 8500 with a 9000 rpm limit.

should have rotional idle and anti lag switched on for friday too, not aggressive though.

awsome to hear Andrew - we werent to sure about them but that's very encouraging and the new dumps are heaps better than the old set up. we picked up 10 odd kw's at 4wheels from the side pipe and lost about 8-9 kilo's.

the -5's are the smaller style of the n1's right? the .42 instead of the larger n1 which have .60..

i beleive thats the same i have on my car, tho they were rebuilt and a 5mm larger front wheel was added.

just reading garrett now, it appears in your case its reversed. you have the .60.

-5s are larger than N1s. more like an HKS GT2530 in housing and wheel sizes.

[Snowman]

They are identical to the 2530's except they are .62 instead of .63. But having used both types in the past it is amazing how much of a difference in response the -5's have over the 2530's with no difference in top end at all.

[Angus Smart]

so if i've previously had the .42 version with now a 5mm larger wheel where does this leave me?

[dontfeelcold]

Is the intercooler piping going into and coming out of the turbos an off the shelf product or custom?

thanks for taking the time to answer everyones questions, its appreciated.

hi mate

yes the piping comin off the turbos, is off the shelf greddy stuff, good gear too!

and no problems with the questions, anytime, collectively there is a whole lot of knowledge on this forum!!

update (just got home)

car has been run in for a few hundred km's, was an interesting drive on the backroads!

back on dyno tomorrow for full tune and see what power and response we can get.

cheers russ

Yes , we have changed from the n1's, will find out if thats a good thing soon enough.

we stayed 2.6ltr because we want to rev it, and feel this is a safer option in that area as piston speeds increase with lengthening the stroke. fine for drag and short work but not as nice on longer distance stuff, i was lucky enought to be able to speak to the tomei crank engineer for a little while about the cranks and set ups while i was in japan, which was very interesting.

cheers russ

eh? you speak japanese russ?

or is that hes fluent in the savage tongue??!

[giant]

nah !! lol

was getting translated for me.

with a strange turbo.... lol

A/R and wheel size are not the same thing by the way.

basically you now have one of the small n1s but with an odd size wheel in it. could be better, could be worse. hard to say.

yes there was a long wait on standard replacment from garrett, so 5mm larger was the closest size up. tho i think it was the whole cartridge replaced..

its so much better now where i lost a bit of midrange/top before i've not got a smoother powerout put all the way thru.

i'm done hyjacking!!

Go team Australia!!

whos the english mob going to tsukuba??

[giant]

okay guys,

update

todays test was an absolute success and was also vital to find out where we are heading!

we broke all our previous PB's, by large margins( the day was very hot, track temp was 52 degrees, so there will be even more in it)

sprint 53.84 !!

national 1:16.6 ( and was held up a fair bit)

car was running 244kph on the front straight !! (on radar)

we had a power steering belt come off in the afternoon and give us a scare as it took out the dry sump belt,

(luckily it warns you straight away as the steering goes heavy and mark shut it down before we had no oil pressure and the car was on decel)

also played with suspension and alignment and got good results.

this is exciting as the power has not been increased yet over the old engine setup (rpm has though to 8500)

i will have some pics and vids up over the weekend( too tired now)

cheers russ

[tacker]

Well done Russ, keen to see the power figure when its dyno'd

[EVO Cam]

Yeah very well done toyou & Mark Russ, the beast was awesome out there today!!

Cheers Cam

i run a hobbs switch (monitoring oil pressure) that triggers two relays...one to cut fuel the other ignition when low oil pressure is seen. It saved our last engine when the oil pump disintergrated.

Well done on the progress guys...I suppose you and Mark are giving Tsukuba a hammering on Gran Turismo 4

[FineLine]

Finally got to see the car in action yesterday. The car looks so much stronger both mid corner and exit speed than last time I saw it. Good luck in Japan guys.

[wrxkilla]

sensational.

will the car be back at QR again before you go?

Also when at Tsukuba, do you plan on letting a Japanese driver with much more experience at that circuit have a steer?

Awesome time Russell!!!

Same question as above, will the car be back at QR on a weekend for the rest of mere working mortals to drool ?

Dirt, can you provide some more details on the parts used and the installation detail? Would you be keen to produce a kit for me/SAU members?
