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

[Snowman]

Hey Russ - what times are you aiming for at QLR on say the National Circuit?

It seems the times there are pretty much on par with say a lap time of Sandown - so us Vics have a comparison to look at (look at V8 Super cars they qualify in the 1.10's at both tracks and looking at the Dutton results it seems that cars were doing the same laps times that did both tracks eg Matt Cherry did 1.19's at both).

Because it would be interesting for us to know how your times compare to someone like Marcov (R32 GTR) , JFK (R33 GTR) and Benno (R33 GTR). I'm pretty sure Marcov's best time at Sandown with RE55's was a 1.14.9. and the other 2 are I think in the 15's.

hey guys

hope to be at the track friday a bit before luch for the afternoon.

snowy - hoping for somewhere in the 1:16 region on the national at QR. (MID 1.17'S last time out, so we shall see)

i would have loved to have got back to wakefield as that is the track we wanted to test at, hoping for high 1:02 at wakefield.

anyone had any experience with AO48's, as nearly all the cars are on them at Tsukuba, ( i have heard they are worth a second a lap)

i need comments??

cheers russ

[giant]

i want a holinger, those gear changes are so fast!!

[Angus Smart]

i beleive we all want a hollinger! how good is that saurus machine!!!

[shanef]

go on russ have a splurge, buy a holinger

worst semi-comp I have used Russ. They were uber crap. They were definitely 1-2s a lap slower than the bridgestones. I understood a lot of the cars run the A048's over there for these comps becasue they get sponsorship to run them...

I have heard the new DZ03's are the go but I haven't used them to be able to fully comment. Otherwise I still think from all the ones I have used that the RE55's are the best to date. (A048's, A032's. R888's, DJ01's, DZ02's, RE540's and RE55's)

[giant]

thanks snowy - i thought they were suppose to be crap too!! (was wondering why they use them, but that makes sense) i am trying the dunlop O3G's at the moment and think we will stick with them.

A holinger is coming!! but it's for that r34, went for a drive in an r33 with a holinger and ignition cut of the gear stick, it was amazing, really linear power.

cool thats for that russ. il look into the whole circlip issue. ps.. that a common s15 issue aswell.

[Duncan]

definately not the yoko a032r they are our control tyres and are slow and horrible (go off quickly)

the dz03 or re55 would be my choice, considering everything else you are doing you should pick up a few sets of super softs and just change during the day.

[sav man]

HPI did a artice on the Saurus GTR, they have 2 engines for it, a drag engine, and a track engine. I can't remember what each one is though, i'll have to get it out to look.

good read.what a serious time for you guy's.c'mon aussie

go russ.

[giant]

thanks again guys!

duncan thats not a bad idea, i cant seem to get a hold of O3G softs but will continue to try (if i cant get them before we go , i will get re55 softs over there)

i have been told that the nismo festival is the sunday before the race!! so i will be there for that, hopefully get to see the 2008 gtr!!

Update

Engine was started tonight!! sounds great!

car goes to CNJ torrow to have new middle section exhaust made to match new tomei down pipes, then back tomorrow night to finish off, start fitting decals and things.

also have to try and get new rear turbo oil feed pipe as it has a crack a the top fitting and is leaking(should have that sussed tomorrow)

wednesday thursday dyno time (after run in)

cheers russ

russ, what were the old dumps that cracked? hopefully not the tomei ones as that what i'm using in my car! tomei manifolds too.

[giant]

Hey Richard

nah the dumps the were cracked were on there when we bought the car! so atleast three years old and look like chinese copies of hks dumps. they were pretty ordinary dump pipes and i'm glad to get rid of them!

russ

[Beer Baron]

yep, the tomei dumps are the best I've ever seen which is why I have set for my car. and I went for the twin 70m HKS front pipes to go with them. very nice quality and the pipes are welded to the flanges on the inside which gives a much nicer finish and no overhang. The HKS dumps (and the copies) are too small imo. sure split is a good idea but in practice you end up with two tiny pipes than then merge again after only a few inches and go to a 60mm outlet. not good.

Giant,

Are you still using the AAC valve and the air regulator on your engine?? If not, what do you use instead of them. thanks.

and which of the 2860 turbos are you using? the -7 or -5?

HI mate

The turbos are -5 , i think! GCG helped us out with these and put the black heat coating on them and changed the bearings to steel cages etc.

with other question is that the valves under the intake manifold? if so , all that has been removed, idles is low on cold start up but comes good in a few minutes.

cheers russ

[SRS13]

Have you changed turbos from N1's to 2860-5's? Any reason why you didn't go 2.8lt?

Do you think this will give enough power considering the Saurus car runs a T88 and a RB30?

[giant]

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
