EGTS Up Why?

Have you cleaned the air flow meter?

No, not yet. Have to wait until the weekend.

Got the gauge going, it's only making half boost.

Normally it'll peak at 15psi and sit on 13psi at 100kmh on the flat in 5th, that gives me 300+ EGTs.
Today at 100kmh I was boosting around 5.5 with EGTs at about 500+

I got both a Dawes and Needle valve.

The only thing that I have done that could affect it was that I tightened up the large hose from the IC a while back, that's the only thing I've touched. That could have produced a leak I guess, it's the original hose, maybe it's overtightened?

No engine mods.

I'm going to check/replace all the small vacuum hoses around that area.

Check the actuator rod function, at idle by having vacuum hose connected to actuator (rod up and lever resting against stop screw) and then disconnect the vacuum hose (rod is to drop down).

Strip Dawes boost controller and clean inside of the body, seat and ball. Mark where it is currently set with marker pen for Ref.

Do that before you touch anything.

I think if he's got a Dawes and and needle set up , and his boost is that low, MAF sensor won't matter would it?? Because now it doesn't influence the boost ??
I can't remember ....
Remember those days Marko? Lol

Thanks for all help fellas. I have to wait until the weekend before I can fiddle with it all.

Another question. I have one of the Nissan snorkels, the ones with that Nissan badge riveted onto them, ex TJM Airflo snorkels I think?

Anyway, how many joints do they have? Just need to make sure it's all watertight. Thanks alot.

To double check how watertight my snorkel was after installation, I disconnected the filter housing from the engine. After taping the pipe off with duct tape, I filled the snorkel with water and looked for leaks. That is when I found that the preheat system on a RB30 is not water tight.

That's a good idea Craig, I think I'll see if I can do that. Might save me pulling it all apart for no reason.
Thanks.

Just make sure there are no sensors in the part you test. I also used a shop vac and air hose to suck out any remaining water.

Yeah but it does influence fuel. I'd be making sure the MAF if clean or working 100% before anything if it were me. Otherwise you might be just chasing your tail.

Im kinda glad to forget those days to be honest. I like my dumb motor.
