Petert Inlet Cam

[kyepan 291]

To trouble shoot out the cam, why not swap it out for a standard one with standard pulley.

 

it would only take a few hours (he says knowing it would take him most of the day) to take the covers, belt, cam off.

 

ps, did the earths get checked?

This might be a route for me to follow. Ideally I would like to have it set up on the rollers with the cam in and then again with the std cam, but that costs money, which is in short supply, bearing in mind this is now my second car behind the gti-6 that I now have.

 

The earths are all good, everything like that was checked when the engine was refitted.

standard fuel pressure regulator so no issues there.

 

Did you check with a fuel pressure gauge that it does in fact have 3 Bar at full load? And that the fuel mixtures are correct? Mi16 regulators can vary enormously. I've seen them vary from 2.5Bar to 3.2 Bar (checked with vacuum removed).

 

The other place to look is the fuel pump. The small rubber hose that connects the pump to the body perishes over time. And/or the clamps loosen. Meaning high pressure fuel flows straight back into the tank.

 

Also check the hose leading into the fuel filter. It can perish internally and a small flap will limit flow.

 

Just because the timing holes line up doesn't mean the cam timing is correct. You really need to measure lift at TDC with a dial indicator before going any further.

 

I'd have to say you're first unhappy customer.

Good of you to help Peter, though at the moment he's not unhappy with your product, just his engine!

Yes, that is what I read as well, some confusion as to why not getting the expected result, and trying to solve I read, as opposed to unhappy with the product.

 

I am sure it will get resolved one way or another.

the induction noise sounds nice and cammy below 4-5k then seems to change to a dull drone as you reach the higher rpms

 

Iv got a stage 2 solid grind on inlet and stage 1 solid on exhaust and i have the same sort of noise pattern as you, up till about 3500-4000 it sound "beefy" then over that it tuns into a much smother "tone" but with the noise you also get a real surge of power, acctualy the surge of power kicks in about 3000 come to think about it, so i think your "dull drone" is normal,

 

my cars not been properly setup yet and the ECU needs alot of work but so ar im very happy with the way my cams act, hopefully will be even better after it has been to emerald!!
