with my boost controller switched off, it will run the minimum the wastegate spring/preload allows, so long as there is no damage to the wastegate lines.

that would be consistent with wastegate functioning correctly :) What pressure wastegate spring limits your boost?

I have often wondered about Wastegate actuation, as over time vacuum drops in an engine and the wastegate seals wear. So unless you constantly adjust it the boost control will lessen over time - good reason not to buy used wastegates.

On a far less serious note, and in response to 2.1 bar boost. In a modified GTIR years ago a friend used to boast that his engine could handle anything failing, so another friend told him to disable all boost control (wastegate locked) and remove the knock sensor for a 10 second full throttle blast. The thing went like a rocket - didn't blow up then, but one week later he called for a tow as he had just played catch the conrod. Motor pulled down and bearings were mushroomed and block had an awesome porthole. :)

lol......epic fail to that Gtir.

Having said that 2.1bar is no laughing matter

Yep, he was initially really happy about proving the doubters wrong until the engine died.

2.1 is high. I remember years ago hearing that Rigoli was ordering 5 bar map sensors, as the 3 bar were out of range on the racecar.

yeah those Rigoli boyz were truly nutz!

I remember their 4WD Hyundai Accent which ran 10secs or less

Waz crazy what they did by transplanting an Evo drivetrain in that chassis........but it worked!

That was the exact car - good memory :) the rumour was 43psi. I think it had a T60 or T70 Turbonetics custom turbo from memory.

Yep. Good times mate.......good memories.

I also happened to own an accent att when they did that lol

Turbonetics rings the bell as well.

Pretty sure I have a FastFour Mag somewhere about it

1.7 bar spring, lots of preload, did a few more tests consistent 2.08 - 2.1 bar, so needs to be backed off a tad.

so wastegate spring 1.7, no boost control gives 2bar? Boost creep?

      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. Rb25det s1 walbro255 fuel pump nismo fpr holset hx35 turbo fmic 3" exhaust freddy intake manifold q45tb q45 maf   Re: s1 RB25det flooding at start up Fri Apr 12, 2013 5:07 am No, I didn't. 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.
