2 days is nothing to worry about.

Chances are he will simply send it out.

Also with regards to the boost controller..

I found the adjustment to be a little bodgy as the top of the spring would often jam in to thread; I bent the top of the spring in slightly and now its extremely smooth and so much easier to adjust.

yeah i pulled mine apart and had a good look before using it. the cut end of the spring was ok in my case, but i can see how it might be a bit dodgy. i have adjusted it once and left it like that (fluked the correct setting first go).

here's a tip. if you want to install it at the least(stock) boost, tighten the nut just enough so when you blow thru the bottom nipple with your mouth, you can just get the air to come out the side nipple with quite a bit of blowing effort.

Anyone have any ideas on what i can do to make it hold boost a little better ???

Hey all as per my post i think like 20 pages ago i managed to get mine working and it has been going strong alot better than my previous turbosmart pos. Anyways i have upped the boost to around what i thought was 11psi. After doing some high load runs i found that it was getting up to a max of 11.6psi at 4500rpm and then worked its way down gradually till 6800rpm when it was down to about 9.8psi. I have checked the lines and they are as straight and short as i can make them. Other than maybe trying to shield the BC from the engine bay heat do people have any other ideas on what i can do.

Summary is below

4500rpm - 11.6psi

5100rpm - 11.1psi

5700rpm - 10.7psi

6300rpm - 10.0psi

6900rpm - 9.8psi

PS i know it's a cheap boost controller and can't expect the world but 1.8psi is a fair drop.

maybe its got something to do with your acuator.

Mine seems to hold boost fine. Unless the spring loses it's tension over time....??

Thats just my uneducated guess.

i set mine to 9.5 -10psi and when i come on boost hard the thing hits 11psi for a split second then sits on approx 9.5-10psi like i set it

if you cut the spring, you just have to screw it in further, best mod for this controller is to remove all restrictors in the lines if there are any and have more pressure acting on it which makes it a bit more accurate. i put the flat end of the spring to the ball, as it seemed like something you didnt want to foul the movement of, as opposed to the bolt that stays still anyway.

bearing i found worked by the way, and i have 12 more here lol. as long as it fits in it will block the end

      R32 clutch master cylinder

      By BASHERnissan · Posted

      Hey team,  The clutch on my newly bought 25 swapped r32 feels average and sticks half way. Went to go order a new clutch master but it does not look like the ones that suit the one that’s in the car…    does anyone know what clutch master is this just by looking ?  (The feed is on the side rather than the bottom like the ones the pop up online)  thanks guys new to the RB scene so any help is appreciated cheers !!

      Synthetic oil versus conventional oil

      Id be more than happy to sign up!!! Where do I send the invoices for my fuel usage? I'm happy to provide the mower, oil, and the labour to abuse the motor, just a little help on fuel would be great...   I had tipped the container of oil out into my big "drip tray" and left the small container upside down to drain the oil out of itself overnight. PIcked the container up today, and it has a layer of what feels like either dirt, or shit tonnes of carbon in the bottom of the container. I'm leaning towards it likely being dust, as I doubt the quality of the Sunli BumbleBee having a decent air filter on it, and sections of my yard produce a dust storm, especially because of the high lift blade!   So, filled her up with some fresh Nulon. Seemed to run fine, but it seems to want to run at really high RPM (higher than normal) even with the governor spring slacked off after fire up to try reduce it. If I back the throttle off it a bit to drop the rpm to where I'd like it to be when mowing light grass, it starts to blow a bit of smoke out the exhaust. Opening the throttle back up clears that out. It's definitely breathing oil, as I put my hand down at the breather hose and it's spitting some oil.   My guess is it having been running at high rpm, oil never changed, and it eating dust has destroyed the rings. You know what that means? Time to send it!!!

      That is what will seal with the bonnet closed. Follow it down while closing the bonnet to see where it ends up with the bonnet closed. The panels don't do anything other than spending money, which this one will do just fine. :p

      Yes, well, one or the other. On R32 (which is the only thing I can look at personally) it's on the rad support panel. You have neither, and it will need to be on one or the other. I must say that the arrangement of holes perhaps looks more like it lives on the bonnet underside on the R34. The rad support panel doesn't look like the R32 one at all. A quick google shows....
