Hello guys,

I have a built RB30 with a 26 head and a PTE6266, I only have access to 98RON pump fuel.

I am currently pushing it to just under 1.6 bar with no pinging but am itching to push it even further. What do you guys think? Would a low 8's Static CR take 1.8 bar on 98 pump fuel?

Any feedback/experience would be appreciated :)

Cheers,

Sam

There are so many variables that the only way to know is throw it on the dyno and see

I built a 2630 with twin GT-RSs and 9.5:1 static comp on E85 and I only expected to run 24psi and so far we're up to 28, went 30 but the spark gets blown out, but going from 26 to 28 it picked up 25hp at all 4, when we sort the spark issue then we will try 30 and see what happens, if it picks up another 20-25 HP we'll try 32 and so on till it no longer makes decent gains or get to high of a knock level

Boost doesn't kill engines poor tuning and preignition does

That is true, but you're blessed with E85. I'm stuck with pump fuel that was why I wanted to see what would be a safe limit.

what power is it making with the 6266 at 1.6bar?

Depends on the dyno really. Mine maxed out at 615whp at 1.6bar. Posted a dyno sheet on RB30 thread.

    • I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'  
    • D2 and Ksport are essentially the same thing and basically just generic Taiwanese manufacture. Better than ChinaBay crap, but... not top shelf. Öhlins have got to be some of the best dampers around, so likely to be a good option. It's going to get to the point though where I suggest you buy from Oz. We have at least 2x excellent options here. If I were you though, I'd be talking to KW about doing something for the R33. There's bugger all difference between that and the 32. In GTR land, anyway.
    • KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.
    • Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.
    • Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
