No top end power, hesitation

[Cheesetoast]

timing was indeed off, pump was set a full 1mm in advance, and my advance lever wasn't working.  Couldn't get the pump timed, he said somethign about the shaft inside could be twisted.  Darn things going for rebuild/repair on monday.  ***ty.

libbybapa,

I never had a problem getting the timing dead on as I would just leave the crank a big retarded and it would pull it right into place, but as I read what you wrote carefully, yours is definatley an easier way to do it. I always slid the cam pully back on and then torqued it to spec, instead of just leaving it loose... ah well such as life. If I ever have to do it again this is what I will do.

Cheesetoast,

Sucks to hear about the pump, I hope you are using this as a good excuse to send it to Giles for some real power.  :wink:

a full 1 mm in advance??? um... that sounds really really really bad!!!

Cheesetoast: I was once recommended to take my pump to a rebuilder near Kinetic Motorsports (for the life of me I can't remember the shop's name), but for less money I was able to get my pump completely overhauled and modified by Giles@Performance Fuel Injection LTD. Benefits are Biodiesel-resistant seals, better power/smoke ratio, and better fuel economy.

If you're quoted at least roughly $600 CAD for stock pump repair, you'll probably get better value for the money from Giles. He however has a few weeks waiting list so your car could be off the road unless you can get a spare pump (NA is fine) to get you by in the meantime...

Mark the place is NW fuel injection.  :wink:

yes, giles does it for $900-$950 i beleive, but apparently my pump has more than enough flow for my setup, i can get smoke anywhere in the rpm, and the fueling isn't even turned up all the way, it's still got some ways to go.  I may upgrade the turbo in the future but i'm not going to be running higher than 20 psi, i don't want this engine falling apart, this daily driver has to be reliable.

i was there when he was trying to time it.  he put the pump timing gauge into the pump, took off the timing belt cover, loosened the pump pully, and he said when you move the pump physically forward and backwards, the gauge is supposed to move quite a bit, it barely moved at all.

I read the thread twice to see if I missed something, and I still don’t understand the problem (timing?,pump?)as it is being described! But I’m pretty sure you are saying your mechanic either set the timing wrong (pump and or motor), and or missed a serious problem with the pump(bent shaft... sounds kinda fishey to me!!), when he let you have the car back the first time! If this is a correct reading of your situation, then you really should get another opinion before a costly pump overhaul. Regards

[jtanguay]

so maybe if his gauge is binding inside the pump, which would describe what you are saying... you're doing a pump rebuild??? sounds to me like this guy is just trying to get some cash from you...

a full 1 mm in advance??? um... that sounds really really really bad!!!

What's wrong with 1 mm? Don't some people run up to 1.05?

well 1mm in advance is pretty bad... 0.05mm in advance is within spec...

1mm in advance is like setting it 2.0mm...  :shock:

I know the mechanic working on his car, he doesn't have internal pump knowledge. If the main drive shaft was bent the pump would no operate at all, simple as that, if the car was advanced 1mm it wouldn't run worth *** if it even did run. I'm not saying there isn't some sort of a problem with your pump, there very well could be, but with the info presented the problem seems to be more related to the tools/mechanic.

Also whats with he comment about an advance lever? If he talking about the cold start advance lever on the back of the pump you don't even need that thing, it doesn't really get cold enough here to need the extra couple degrees of dynamic advance on a cold start.

There is a TON more that goes into that pump then adding some more fuel, the timing mods that he does, the extra gain he adds to the pump ect... If you had him build you a performance pump that flowed the same amount of fuel as you do now, it would still be night and day.

Look at the NA pumps that he builds, and the extra power they get there, its not like they can just magicly add extra air by turning up the boost to burn more fuel...

But hey its your money, do what ever you want with it.

hmmm seems like everyone is ganging up a little bit on cheesetoast...  but seriously man... ditch this mechanic and get a giles pump STAT!  :twisted:

can an engine seriously run at 2.0mm timing??? like wtf... i personally would imagine cool egt's, but severely overheating pistons/head/rings??? mainly because the combustion process would 'linger' inside of the cylinder that much longer...

any other theory's? do we need to make a poll to see how many people think cheesetoast should send his pump to Giles?  :lol:

[jtanguay]

I also don't think anyone is ganging up on cheesetoast, I think they are trying to help him out.

that's what i like about this board!
