T04Z is regarded as the biggest you can go before you need to upgrade mountains of crap Matt.

yea I know hence I dont see it coming on at 3,500rpm to make 760hp...despite this I wouldnt be suprised if it is making 800hp that its broken at least a gearbox/tailshaft or something....thats all im enquiring about.

if anyone acts like a tool we will throw them out, its just about having a good time.

Does that include if you want to drift around the track.......... sorry but that is what I'd want to do, going fast has lost its sparkle, its all about the drift for me now.

Hope you all have a fun time though :).

Club members could compare kw @ teh wheel though before they hit the track, the day before this is a club dyno day :)

780hp at 3,500rpm?....is the car even on boost at this rev range I imagined a T04Z coming on pretty late? I take it you dont drive this car around on the street all the time, 25psi of boost would require quite a substantial amount of fuel support and hence im sure the bill would be huge. Im also assuming you are talking about a HKS T04Z? May I ask how your going on gearbox's/tailshafts/diff's etc?

Broken a couple of gearboxes and not standard ones too ,the diff and tail shaft has been fine ...knock on wood ..lol with te to4z which garrett made for hks and hks developt more on it ,its only a t4 turbo and a good one which produces very well horsepower at early reves ,i proberly confused you ,i mean boost comes on at 3500 reves ,which is a good set up for over all racing and also depends on how your motor is set up too ,..i know of some people it comes on about 4000 plus ..

with my motor i could have bigger turbo producing up to a thousand horspower but bloody useless for track set up when boost comes on 5500 reves plus, no good for cornering and uncontrolable ..good for drag set up ,only if you got nos to stop turbo lag and a good ems to run it ..plus the fuel bill is not too bad unless you put yah foot down and it s on 25 p at all times due thats how motech is set up or tuned ,and motech dont have electronic boost controller it has everything else but that ,..i dont know why ,its ment to be the best ,but its worked real well 4 me and keeps the car running very well ,if you can find a good tuner that is .who knows motech ,as not many do .

      They care about emissions, and cost the most. Save weight where possible, and make manufacturing easier. Less material also let's the engine transfer heat to water quicker, and bring the engine up to temp quicker, better for emissions and getting them past their warranty period.

      I was under the impression the reason why OEMs are going with solutions like relatively thin "right-sized" cylinder walls with technologies like PTWA and open deck is because they care a lot about whatever marginal knock margin benefits they get from that vs the structural rigidity benefits of a closed deck block and thicker cylinder walls. I also see some weird stuff like plastic inserts in the water jacket around the cylinders to try and equalize cylinder wall temperatures. re: the PRP blocks and heads at the end of the day it's hard to know what is and isn't going to work there, just have to see what the initial buyers say about it.

      Which is why I didn't mention that hardness testing, and specifically mentioned the bore and deck thickness testing. Yeah, not really. The bore temperature will be a lot more even around the top half inch or so, where the material distribution is dominated by the deck, and which is the only place where the bore surface temperature heating any gas in the cylinder is likely to have any effect on detonation. Think about it. Another inch or so down the bore, you might have a hotter spot. The gas there might get a bit hotter, then the piston rises squeezes that gas away from there at high speed and mixes it with other gas from nearby. Instant dilution of the problem. I'd be surprised if it was an issue at any time other than in racing engines or OEM dev engines being run at the ragged edge of tuning. Say what now?

      https://dsportmag.com/the-tech/education/engine-tech-material-hardness-testing/ The PRP testing on block hardness I'm not sure how much it actually can be trusted. The thinner cylinder walls on RBs is a bit of a problem vs 2JZ but it really depends on the design goal. Siamesed cylinder bores like a 2JZ cause uneven cylinder wall temps too, which means a bit of distortion induced by that + the hotspot can affect knock margin. Something that actually gives me a bit of pause with the PRP block, whether super thick cylinder walls are going to keep it from being drop-in compatible on an otherwise OEM rebuild.

      Yeah very valid point. I am waiting for one of the other tuners to come back from vacation so he can help me a bit when the cat is installed again. In the meantime I am going to finish up my polishing and ceramic coating that I have started myself.    N45 Dr Beasley product is highly recommended for a paint primer / polisher. Using this EXO Gtechniq also for the ceramic but next time might use the light serum before hand also. Looks great.
