[KILL HSV]

yes

nice

[West]

I'm runing 14psi with cam gears, pods, zorst and PFC making 253kw@w. Stock pump, injectors.....

[Ronin 09]

West - can you post your dyno so I can compare the midrange to the Tomei cams?

[Beer Baron]

yes please! I'll be heading back to japan soon and am trying to allocate my luggage space

[Ronin 09]

Heading back to Japan eh...

I overlaid my graph on a UAS dyno I found on their site here

I PDFed the excel spreadsheet, as attached...

[Beer Baron]

yes, and no I won't bring you back any parts/kobe beef/school girls! haha just kidding mate.

Yeah, I'll be heading back soon. it's worth it for me just for the money saved on freight.

BTW your dyno graph really impresses me. I'd love to come for a ride to see what your car feels like. ie. how responsive, what the top end is like etc. because I'm pretty much doing the same things.

I currently have:

front pipes + cat back system

Apexi PFC

profec b-spec 2 (running about 12psi)

Apexi power intake kit

trust cam gears (not yet tuned)

HKS wastegate actuators

want to add to this:

trust dump+front kit

cams (not sure yet which ones) + valve springs

possibly GT-SS turbo kit

[Ronin 09]

Richard, that sounds like a good list - I think my turbos run out at the top end, so something like a GT-SS will keep the boost on early yet flow alot more for better top end

If you're ever in Melb, I'm happy to take you for a spin

[Beer Baron]

I do pop down to melbs from time to time. mainly when the GP is on

yeah, I think the GT-SS would be worthwhile. not very expensive either. still tossing up whether or not I should go one further to the 2530s.

I'm runing 14psi with cam gears, pods, zorst and PFC making 253kw@w. Stock pump, injectors.....

Sounds very similar to mine..14psi, HKS cam gears, apexi pods, full exhaust, Power FC - 252rwkw's.

[Ronin 09]

GTR032 can you please post your graph?

Thanks

[GTR032]

GTR032 can you please post your graph?

Thanks

I dont have my latest graph unfortunately but here's the next best thing. 244rwkw, Blue line is 14psi, cam gears, power fc, filters,full exhaust and rebuilt turbo's. Red line is 12psi, pods and full exhaust - 188rwkw.

Clarification: So 1bar worth of boost on the stock turbos seem to be okay? Is failure past this because of the actual boost or the fact that the turbine shaft speed is too fast causing delamination?

The reason I ask is because I am about to undertake up grades in the way of a competition dump pipes and y piece as well as a retune on the dyno. I already have a larger free-flowing FMIC and pods. What worries me is that with all these mods I will have less restriction in the system and therefore less boost. If I then up the boost to 1bar I would imagine the shaft speed will be greater than a near standard system with 1bar.

Am I on the right track? If so, should I tune for 0.9bar or even less?

So is it the boost or the shaft speed?

Still had no concrete reply. Given that I have less restrictions in the system should I be aiming at only 0.9bar boost or less? So is it the shaft speed that causes the problems or purely the amount of boost?

West - can you post your dyno so I can compare the midrange to the Tomei cams?

I'm sure with cams you'll get more midrange than mine, i can post the dyno graph but it'll take a while, best to speak to BEN, my car was on the same dyno as your or maybe come to the meeting this month?

Where about in melb are you? Pm me.
