How much boost pressure should my 1.6 TD have?

[scrounger]

Cool I have a k24. How many PSI should I shoot for?

15 is safe if u want more get an egt gauge, intercooler, and a bigger exhaust.  Or I'll end up breaking stuff or melting stuff eventually.

Increasing fueling? Can I turn in the diaphragm adjuster on top of the IP?

About the only adjustment that I have made is turn down the idle. It would just take off in reverse. I have it bottomed out and I think it is still too fast. That is a different topic.

Thanks for the advice on max. I don't want to burn or melt anything.

Are you sure you turned the idle screw and not the residual fuel screw?

[scrounger]

I turned the screw that the linkage presses against when at idle. It had a 10 mm lock nut on it.  It is on the side of the IP that is toward the engine. Not sure but if on a gas engine it looked right.

Does your pump have fast idle? Basically a rod up the back of the pump (closest to the engine block) that goes from the cold start lever to a lever on the back of the top of the pump.

Hi burn,
It has a fine wire on the engine side of the pump that runs to a yoke.
I usually just keep the "choke" lever pulled out all the time.

See the metal rod that is almost vertical? Do you have that?

[scrounger]

I just went out and started it. It seems to make not difference in idle speed with the start cable pulled out.
....
Just saw your post showing the idle speed up linkage. Mine doesn't have that. Just the cable at the bottom at an angle and the throttle at the top. No other arms or linkages.
thanks

[burn_your_money]

Alright, you adjusted the correct thing then.

[scrounger]

Thanks to you and others. The linkage just bottoms out and leaves clearance on the bolt adjuster. Every gas engine that I have worked on would idle so low that it would die if I set it so.

Your gauge will likely buzz like a mad hornet, easiest fix is stuffing cigarette filter wadding into the gauge tube at the end you tee it into that little boost pipe, keep stuffing until satisfied.

Hi Smutts
I don't get a twinkle of a vibration surprisingly.
I used 6 feet of vinyl tubing.The tubing is 1/8" heavy wall  and with only 9 psi I wouldn't think it to be flexible enough to dampen things out.

The gauge cost 15 the tubing was another $1.25 for the length, Oh and a couple for the tee. Adding a pack of ciggys might put my project over the top

It really depends if your gauge has a hard stop at zero or not... Mine is actually a vacuum / boost gauge meant for a gasser, so it doesn't have a stop at zero, and as a result it doesn't buzz even without a buffer.

Where did you get the cheap guage?
