Timing Advance Spacer...

[RSWORDS]

Hey guys Alwaysworking (the guy that makes the M&H pins) has a spacer that is supposed to add mor timing advace while keeping the stock base timing (unless you bump it) this should allow you to run not much advance for bottom end but high advance at WOT so you can flow those big injectors... He says it adds 1mm of timing. and on a pump set to teh stock 12.5* base timing it will keep that base and advance to 31*-32*

Here it is...


And what he says he got from testing, the numbers they use are timing piston travel from
1.9-2.0 mm @1000 rpm pump speed
to 3.8 mm @1000 rpm pump speed

and went to 6.4mm @1500 pump speed

from what he said the engine speed is double the pump speed.

I'm really looking into this, any thoughts?

here is teh lik to the whole thread if you want to read it...

can u give a lil description as to how it works? where it goes? im not to familiar wih the timing stuff on a ve

[Bad93Cummins]

What''s the point or purpose of advancing the timing?

More power on the upper rpm's. Little less low end torque. They say it also lowers EGT's. ( I see a lower egt but still really wonder if the piston is still as hot as before )

He also says.

2.6 max dynamic timing stock
to
6.4 max dynamic timing with the spacer kit.

I don't know excactily what that means but it sure sounds cool if the dynamic is more then double. That being said, what does it mean. Would it be compared to stock timing at idle and lets say a 1/8th timing bump at 3000 engine rpm's????? Can someone help me understand in simple terms?

Has he verified that nothing else bottoms out before the timing piston hits the spaced-out plate?

I like the idea. What's he going to sell them for? Should be a super simple install.

[dragrdan]

Only adding 1mm of travel shouldn't give any problems, I shaved 1.5 off my piston, and had no clearance issues.
Selling them for $105 shipped.

Have you verified advance with a timing light?

Why not make a 2mm one?

can we put this in dummie terms for me. If i have my pump slammed to the head and the pump see's 3400 rpm how much timing we looking at?

what you are doing by moving the pump is adjusting the static timing .

this is very much like turning the distributor on a gas engine .

the spacer in previous posts is like playing with the advance weights and springs that are located within the distributor .

what the spacer is intended to do is add more advance at higher rpm's . it should have no effect on the engine at low rpm's / idle .

alot of vw guys will modify the ve's case to allow more travel of the timing piston to make power well past 6000 rpm .

i understand how it works just wondering about numbers?
I know every truck is differen't but what is a real world number for timing advance on a stock truck.

I just spoke to him on the phone, late next week Im going down there to get the timing spacer, fuel pin and FINALLY a 366 spring. He is about 1/2 hour away from me so I will have some drive time on it and let you all know what I think. Although the if the 366 spring does as much as everyone says I may not be able to tell what the timing plate does.

Do us a favor and do them 1 at a time, do the 3200 spring, then teh fuel pin, the the spacer and tell us the difference you feel with all. I also dont think you will see much benifit from teh spacer w/o large injectors.

I can do that, it will be quick tho as Im really wanting more out of my truck. He was saying that on his truck with what he believes to be 190's the spacer made a big difference so Im hoping it will. I want bigger injectors just REALLY not sure what I need, I have an he351ve turbo that will be going on in a month or two whenever Fleece comes out with the controller and I keep leaning towards big injectors but I want to tow with it so I dont think huge injectors are the way I should lean. I want 6 x 16s then I think 435s would be a better fit but cant find a good source for either....... anyway sorry not trying to write a book or jack your thread. Ill get that stuff in within a week or so and one at a time.

I will predict that with really big injectors this mod would have a negative impact. With really big injectors at max flow they can really drop the case pressure down. Since the timing pistons position is controlled by case pressure, not rpms I could see this mod providing extra timing at low rpms/early fueling, then retarding timing as fueling increased and rpm's increased and the case pressure dropped. This is exactly backwards from what you want. On smaller injectors it should work very well, only big flow fuel systems experience this timing drop issue.
