14psi ?? Interesting....

Using the stock turbo and stock ECU im currently at 272rwhp. I'm still quite confident I can get the stock turbo much higher than that (well 285+ rwhp) with probably another $2500-3000 of various minor mods.

Jet..

~200rwkw is pretty much spot on for a RB25DET with a standard turbo running 14psi, aftermarket ecu, fmic & exhaust.

Some RB25DET's are freaks and make ~200rwkw with the above except without the aftermarket ecu.

i.e Bugalugs that also ran a 13.4 1/4 recently.

If I had a RB25DET turbo i'd be running it at 17psi.

You can't really compare the 14psi limit of ceramic turbo's when using a larger turbo on a smaller motor as at 14psi on the smaller motor the shaft speed of the turbo isn't going to be anywhere near as fast as it is on the larger motor. So up the boost so it is :D

Heat also kills ceramic turbo's.

So if you hammer it on a track day be prepared to loose a turbo.

I have noticed a trend with turbo's that are factory fitted.

For example the RB20DET makes 160kw at the flywheel, when boosted to approx 1bar they make 160-170kw at the rear wheels.

Same with the RB25DET's, they make approx 190kw at the flywheel and when boosted they also make around 190-200kw at the rear wheels.

Stock turbo and Stock ECU?

What mods u have?

Joel, this discussion will probably lead to the accuracy of the dynos. some dyno show better result than others. my car have all the mods you'v mentioned and it made 165rwkw at 14psi on a particular dyno. 165rwkw and 200rwkw is a huge difference, but in fact they might be generating the same power. you get my point?

    • And at over $2 per litre I'm starting to consider setting up a corn mash still and converting over to alcohol and running mine on it !  Up side of that is it all doesn't have to go into the car ! Win win !
    • H2 (for cars) will never happen. It's not reasonable for any number of reasons. It's also not reasonable for almost all of the industrial uses that the fanbois say that it will be used for, again for a large number of reasons. There are some cases where it will be good. But, even those will be massively hampered by the economics. The only way that H2 can be economic is if we somehow manage to get from where we are to the other side of the economic-valley-of-death in which no-one can operate. You need there to be sufficient renewable generated electricity to be available so that it is effectively free. Once you are there, you can do whatever the hell you want and hang the efficiency. But until you get there, the ever diminishing value of electricity makes it harder and harder to encourage businesses to build the new generation capacity, and they will simply stop investing in generation projects. (I kinda think there needs to be just government money spent on building the required capacity in a non-commercial way, similar to how the first fossil fueled grids were built, as national-government owned utilities. And probably some nuclear in there to start. But this all should have started 10-15 years ago to avoid the chasm of death that we face right now). Synth fuels will be much more likely, but will only occur is there is at least some renewable H2 production, because you need H2 to do it. And you need stacks of free (or at least extraordinarily cheap) energy because assembling molecules back into fuels is exactly the opposite process to burning the fuel, and the reason we burn fuels is because there is so much energy squeezed into each molecule. So you're somewhat subject to the same economic valley of death problem as above anyway. That is unless people are willing to pay the current equivalent of $5 or $6 per litre of petrol-ish liquid fuels. Can you imagine it? The squealing at $2 now is bad enough.
    • This is so cool. Get a dashcam that records audio and hopefully you'll catch it.  Maybe there's a brand or some kind of markings on the back ? Are the pics hand drawn? I love it so much.
    • Hahaha yep, point(s) taken. I just like seeing different things and an EV in an R32 is pretty different. I'm not on the EV band wagon, I'm waiting for synthetic fuels or hydrogen personally.
