Jeff.
Suppose it depends alot on what people are after and what they use the vehicle for?
-
But but but...
What if the flow of air (lbs/o2) runs off the x axis or goes above the surge line to obtain that 1.5 bar?
Will it take longer to get that 1.5 bar or just nevah happen?
Hehe just threw that in to see what reaction it would get from your tired state!

JPM's are up.... http://www.jpmphoto.com.au/motoconcepts_days.htm
Some good pics there - including Roy's 85 degree drift in his Hino truck -

Was fun, I heard that there isn't going to be a Motoconcepts day for the month of Sept - time to go to Wakefield?
-
Sounds like rego or i.d. check. Do they need to be Aus DOT approved or old jap ones ok?
-
Ok, got my car dyno'd today. Having some boost issues with it - apparently it hits 1.4 bar then dwindles down to .7 bar at 7,000rpm.
Going to have to get someone to drive my car tomorrow at EC, or to play with the EVC... Volunteers anyone?
-
They've got that wastegate on special! Sounds about right if they are knocking up a plate to adapt the turbo onto the standard manifold with that small wastegate.
-
Merli, just discussing the point - there is no "hard" data to support the arguements that HKS turbos are a) more efficient and B) make more power than an equivalent sized ball bearing turbo. That's the only point i'm making, and asking around to see if there is any actual data supporting that case.
Don't take it as an attack on you comments, I've got a HKS turbo on my car too. Would just like something more tangible than old wive's tales.
-
That's a pretty good deal since they list the 35R at nearly $3,000, the manifolds at $2200, and the wastegate at $600.
Would suit a drag car/larger capacity motor at that size too.
-
Hang on, people are actually making money in F1?
And here I thought all motorsport was a financial drain (but a good development/advertising agent)!
-
But are those designations a GCG special (i.e. a product made up from Garrett parts and named whatever they want) or untouched items made by Garrett specifically for the Australian market?
My bet's on the former.
-
Ahh ok. As for my confusion, Garrett don't make a 2530 designated turbo - they have the GT12, GT15, GT20, GT22, GT32 etc. lineup. Hence why I thought you had a HKS 2530. Maybe others had that train of thought too....
-
woila
EDIT: what about the wheels? Are the genuine HKS items or Garrett bits?
-
Oh and Fat32, does the exhaust have "HKS" cast into it?
-
Rev/Merli, you say that the HKS 2530 is in it's efficient range at 1.4-1.7 bar - at what sort of CFM/lbs O2? Do you have anything on paper to show this? Not having a dig, but scouring around looking for comp maps (heh no such luck) or some "real" data/facts regarding the HKS lineup - and I don't mean my uncle's neighbour's daughter's boyfriend's friend said xyz. By what measure are you quoting these figures?
-
SEVS is used to determine if the vehicle is eligible to be imported, where a RAWS has to import/comply the vehicle. Was supposed to be implemented 8th May, not many people have gained licenses (too many are waiting for someone else to cough up the cash for testing etc., then copy them!).

R33's have steel compressor wheels, right? How high can you wind up the boost on one of these turbo's with nylon compressors?
Heh did you want a reliable figure? Disconnect the hose to the actuator and see if you don't.
-
I've heard prices are now up to around $7k for compliance. With the monopoly that's going on at the moment and the large costs involved to get the license people can pretty much charge what they want...
-
Check out that dyno graph on the ~1000 hp viper (1st link)..
All this mayhem can be yours under 5,000 RPM!!!
-
Solid lifters. Nuff said.
-
Sly33, did you get the HKS actuator with it? Or going to run a standard one?
-
Kinda got sidetracked - as for some dyno figures...
Rick Shaw has a 2540 on his personal car (it's up for sale btw, as you would expect it's immaculate and everything has been rebuilt) and has dyno'd ~230kw at his shop. That was at 1 bar boost - his standard fuel system limited this.
-
Hah now that question deserves a long, opinionated answer...
Depends on size of budget (is $5,000 cheap or is $30,000 cheap?), driving style, access to facilities or contacts, maintenance budget etc. etc. You could write a book on it (I'm sure someone has).
Bottom line (in my humble opinion, and stated a million times in other posts)..
* GT-R's cost more initially, increasing performance costs less, marginally higher upkeep
and the inverse for GTS-Ts. Get a 180sx - cheap to buy, cheap to improve performance, cheap to maintain.
-
Heh have to wait and see what sort of rushed effort goes into/onto the car this weekend....
-
I'm not driving the car much on the street anymore- suspension is too harsh, exhaust too loud etc. for it to be very comfortable to drive. Just going to use it for the odd trackday, so not concerned about drivability anymore. If I was, I wouldn't remove the 2530

It's yellow - I have one if you are interested...
