I make this public, I think this is probably the highest HP out of a high flowed R33 turbo ever archived with 98 fuel internally gated. This is our PU high flow option.

Once thanks to Trent at Status for excellent tuning work.

Fully stock RB25det engine with forged pistons only.

800cc injectors, Nistune ECU, FMIC, Exhaust and 3inch intake pipe.

Car peeked 305rwkws @ 21psi, full boost by 4200RPMs. The average run was 300rwkws.

Yellow line is straight off high pressure actuator, no boost controller. Green line is with boost controller.

What makes you say the airbox is causing a restrction?

Thanks for support guys. Details of this high flow through out development and manufacturing is in our high flow thread.

I took Jeff for a spin that night with air box lid on. Very noticeable difference in how car reacts to throttle compare to a POD. The car was dynoed with a POD and 3inch metal intake.

I got some video footage I will put up later on.

Might be valve springs, I'm not too sure. I did hear a light pop just before the rev limited kicks in. That little dip is always there. Any thoughts would be great.

that is in .82 rear. The difference with an Air box would be, well it sounds very differenct lol. It just doesn't pull as hard, and feels like I'm down in torque.

Is it running out of flow around 6500rpm and hence the nose over?

Or is that being caused by something else?

I dont know much but I dont understand why everyone worries about this so much, Its just a high flowed stocky and usually I'd be clutching by then anyway..

you wanna bounce of the rev limiter get a better turbo (and a better engine)............

This turbo has almost 150kw gain from 3500 to 4500rpm and for the street legal ,that is crazy and affordable power .....

Well done Stao :ermm:

be interested to see a pod power pull followed by one with the stock airbox. i'm sure there is a point where the stock airbox becomes a restriction but it would have to be up around the area you're operating in.

great result!

congrats on the results mate, iv just purchased a 0.63 version of these turbos from another forum member. what can i be expecting from that?

Would you know the member's name and which forum it cam from? They all got different profiles in them refer to what the original customer wanted to do. Or you can pm me a photo of the comp wheel and turbine wheel I should be able to tell you what it is and what its capable of doing.

      Hello, sorry for being late to join the discussion, but my clock just died on me.   Ive tried to look at Michaels digital clock repair.docx and it doesnt work maybe the file has expired.   Please let me know if you can re upload it or take some youtube videos to show us how to get the clock installed? thanks

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
