Not likely mate Piggaz 2.8L stroker with all the fruit is probably at around 20psi @ 4K. Full boost on your car would be around 5-5.5K id say.

I'd hope not - my GTRS's were on full song @ 5.5krpm.

When I had -5s, the turbos were getting tickled at about 3.5krpm and pretty were in 'get up and boogy mode'.

Both examples on 2.6ltr.

Sounds about right.

That thing of Paul's is a weapon, and not the average build. It's got ALOT of rnd and tricks, all of which work. A lot of secret squirrel.

yep totally agree with you.

IMO -5s on stock 2.6 will see full boost around 4.5-5K - if you get it earlier than then I want to know.

firstly are you really running 25lb????

secondly if you are, how bout you throw a dyno chart with boost / rpm curve so we can see at what RPM your really making at full boost with -5s....then we will all know.

I'd really like to see an overlay of -9s with -5s on a dyno graph.

:)

Does anyone have this info or happy to post their graphs running -9s and another with -5s...from here, we can overlay to see the difference...would put a lot of debate to rest

There is one out at unigroup on the same car. On the dyno, they came on exactly the same but the 5'a made more grunt. However, to drive they were a TOTALLY different car!

What's wrong with running 25 psi Ants? :P

LOL....I was wondering when you were gonna say somethin.......aside from being a ship load of boost nothin really just curious.....about how long an engine would last if predominately driven at that boost level :glare:

That is odd Paul. Dyno shows that they huy full boost at same rpm?

Didn't answer the question.. why the doubt? I am offended.

Ill try and get the sheet. Or it could have been the power low end was the same but boost levels were pushed to the right a tad on the 5's.

Leave it with me.

I spose the tune would have a massive part in this. Mine lasted 7 years with anything upto 2.0 bar shoved down it... Only died because the oil pump had a hissy fit.

yep totally agree with you.

Mate I watched a built 26 with -5's and poncams on a dyno for a good hour and full boost was by 5000 and it went to 345kw iirc. No chance of getting -5's in by 4 on a 2.6L ;)

IMO -5s on stock 2.6 will see full boost around 4.5-5K - if you get it earlier than then I want to know.

I know Paul.....I know. I'm just conservative and want to have an engine tuned to last as well (I will certainly not push my advance spec beyond 25psi). Your car is insane and would of loved to have a 2.8ltr with similar mods to yours :)

Keen to see those graphs though.

    • http://calfinn.com.au/product/1500kg-standard-trolley-jack-cj-2t-c/1500kg-standard-trolley-jack-cj-2t-c   I have this and fits under a S3 33 GTR with no issues. Purchased in 2009 and not one issue. It was $950 back then. Not cheap but something so important isn’t worth cheaping out on.
    • Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?
    • Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).
    • Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).
