09ONE_32 Posted June 30, 2008 Share Posted June 30, 2008 (just re-read the first page) im just a little skeptical that the old shitter T04e would rack out 400rwhp… especially dropping to .9 barI had one of the largest variants in a .82A/R rear (and a few people i know had similar turbo specs years ago) and it was no more than 240rwkw at best with 13-14psi, and best mph of 112-113 I mean, if you have a fairly mighty MPH around the 120+, then fair enough. Not trying to take the thread further off course, I just find 60rwkw a bit much to take for identical setups bar ECU. That could be one reason your motor is together Anyways, when you see the RB26's fail with say, what, 350rwkw doing circuit work. RB25's go down the near enough same road. As an example, you could make 350rwkw and run it daily as a street car, but fact of the matter is your never going to see much past 120km/h for longer than a second or two… And the motor is hardly going to see 350rwkw on a daily basis now is it? People saying that’s the case are kidding themselves. Also remember motors running like this are under nowhere near the stress that a motor doing weekend track work would see with regular expeditions into the 200km/h+ zone and sitting well up in the RPM scale at the same time, for a long time. I reckon you probably could have a motor crank out 350rwkw. But would it be reliable? Depends on the situation and most likely not forever. Max power and reliable power are different. If a motor can run 350rwkw for 5+ years…and by that I mean seeing 350rwkw daily on a factory bottom end, I'd be surprised. I agree totally. When people compare how long an engine has lasted they really need to take into account what the vehicle is used for. I have busted 2 x RB25's on the track with 280RWKW @ 1bar. They both lasted for about a year before letting go. I am sure (know for a fact) that they would have gone strong for lot longer if the car wasn't almost purely for trackwork. I have all the support mods and a very very safe (read power compromising) tune on low boost but the kind of stresses that they have to put up with on the track is just asking too much from a 15yr old factory engine.

thebe Posted November 1, 2017 Share Posted November 1, 2017 Pretty impressive power for an engine with no crank, no pistons and no rods. With good enough turbo and supporting mods you dont need them. On a high powered engine the oem ones are the weak-link anyway so better get rid of them straight away[emoji85] Link to comment https://www.sau.com.au/forums/topic/194476-rb25det-max-rwkw-with-stock-bottom-end/page/4/#findComment-7857105 Share on other sites More sharing options...

Just the basic.. hahahaha wow $20K spent on bolt ons and keep an "un-opened" motor - is that just for bragging rights? Neo motors are stronger than R33 RB25s "out of the box" so that's the way to go in this context. As other's have said above, "it's all about the tune" to keep the motor safe (safe-ish) at those HP figures - and running E85 (E87? I don't know what that is?) as you've done is the way to go for ethanol's resistance to detonation. Impressive horsepower - well done! cheers Mike Link to comment https://www.sau.com.au/forums/topic/194476-rb25det-max-rwkw-with-stock-bottom-end/page/4/#findComment-7857207 Share on other sites More sharing options...
Dose Pipe Sutututu Posted November 2, 2017 Share Posted November 2, 2017 Ethanol won't save ringlands though, mine died after a solid year of abuse at Wakefield making 372kW. Prior to that nearly 2 years at 330kW. 2 Link to comment https://www.sau.com.au/forums/topic/194476-rb25det-max-rwkw-with-stock-bottom-end/page/4/#findComment-7857215 Share on other sites More sharing options...
mikel Posted November 5, 2017 Share Posted November 5, 2017 A different perspective is my recent experience, where even with minimal horsepower (~205 KW), a bad tune and tuner wrecked my bottom end. It was never a good idea to slap a NEO head onto an R33 bottom end, but 2 workshops (the 1st workshop put the head on and dyno'd it, then another did further work and dyno'd it) never mentioned anything about not putting a NEO head on an R33 bottom end. 2 years later and the compression across the cylinders was all over the place and the bottom end was wrecked. Probably less due to tune than tuner - but they go together. The cautionary tale is that these engines (any engine) can be damaged with poor tunes and tuners - even at modest horsepower. @Chris90 and many others have shown that the standard RB25 can take significant horsepower when tuned well. In Chris's case - he knows he's pushing the boundaries - well done - after all if one pops he just sources another! cheers Mike Link to comment https://www.sau.com.au/forums/topic/194476-rb25det-max-rwkw-with-stock-bottom-end/page/4/#findComment-7857451 Share on other sites More sharing options...
Guilt-Toy Posted November 5, 2017 Share Posted November 5, 2017 one i did, basically a standard budged build rb25, i think the whole car owed the guy under 6 grand standard intake and exhaust manifolds the car lived on limiter and it lasted a whole 2 months of disrespectful abuse before it broke a rod the car still ran with the broken rod handing out the side too lol 1 Link to comment https://www.sau.com.au/forums/topic/194476-rb25det-max-rwkw-with-stock-bottom-end/page/4/#findComment-7857459 Share on other sites More sharing options...
