Does this work?
« on: December 11, 2017, 05:24:52 pm »
Are these any benefit to a standard 1995 C10? My bike has got the full power carb tops, Motad silencers, Iridium plugs and K&N air filter.
Thanks  ;D

Check out Steve Sefsick's exhaust cam sprocket @ shoodabenengineering.com. You won't be sorry.

I've got the price off Steve for the Ex sprocket. I'm asking about the timing advancer, not an exhaust sprocket  ;D

Ask Steve what he thinks. If anybody knows about smoke and mirrors it would be Steve.

I seem to remember a thread back on the old forum about ignition advancers.  From what I recall, they offer no benefit to the C10.

Yes and mostly NO.  Timing advance can work and might get you something on the top end but you dont want  it in a lot of places.. lower RPM's with heavy throttle input  for example.
The problem with a static advance is  - well - its static- and you dont want that. It would be nice if you could only have it for lets say- light throttle cruising- to get a little better gas mileage but it sounds like you want more power and not more fuel economy.

Also , all the dyno runs I have seen   show ZERO improvement  so dont bother wasting your money.

What is it that  you are trying  to do    is the better question?

 I slotted one stocker and on another C10 came with a V&H advanced plate.
 Slightly helpful on low end power at seat of the pants dyno.
 Unhelpful in high air temps as seemed to be more likely to ping at low rpm lugging the engine at take off.

  Most folks have no clue about timing or haw devastating to much timing can be. As mike said, the advancer is to initial static timing. that means the advance is added across the board, at all throttle positions. Generally, gas engines run around 36* total timing at highr roms and heavy load. as compression pressure / heat increase, that number continues to come down and never goes up. Add +4* timing to a connie at stock 35*, and now you have 39* total. all in at 3500 rpm, and then you do a hard roll on. Guess what happens? Gas Knock. Go ahead do it again... at some point if everything isn't just right with octane and engine temp you're probably going to damage the pistons. It's the law of unintended consequences. Steve

Too bad the ignitor module can't be flashed with a new curve, I bet you'd have some fun with that!

Thanks for all the comments ;D
Seems that the advancer is a no-go, I'm not after high rev gains, just the opposite, I want low speed throttle response and more torque.
Just need an exhaust camshaft now and the engine will be ready for another 87,000 miles  :great:

Mike- For a few bucks more you can get Steve's torque cams. I've got them in my 06 and you can really feel the difference.

I've tried to buy a set, but he hasn't got any right now. I've also got 3 pairs of standard camshafts but he says the shipping will make it too expensive to make it pay. I'm fitting the best I've got as a temporary fix  :o
