Engine/Transmission (1994 - 1998) Proper Ajustment of Govenor Arm and #10 Plate

[MM800]

I moved the plate forward on my 98 and now the gov arm seams to hang up on the nose of the plate. It appears to be a little low. I'm not sure if I understand the instructions completly from the Piers site. It says a little low is ok, but it seams to hang up a little. This is with the engine off, fuel up position and moving throtle linkage by hand. Does it hurt to be a little high on the plate?



Thanks

Try moving it up a little and see what it does. Experimenting is really the only way you'll find out what works for you. While pulling up the solenoid and moving the throttle by hand helps with getting an approximate location when adjusting it, it actually will contact the plate in a different place when the engine is running due to the governor getting involved.

JGK,

Noticed you are running a PDR cam. Which one? I have a built motor sitting. Waiting for a slow time to install. Hopping I can drop my egts. How is the 18 degrees of timming working. I'm running 16. Is it worth bumping?

I think the cam is/was PDR's mildest cam. Can't remember for sure since it's been 4 or 5 years since I did it. As I remember, it added just a few thousandths of lift and just a couple of degrees of duration. No cutting of pistons. I can't say I really noticed a big improvement but I think it runs cooler and boost is a bit lower (less restriction on intake). When I put the ported head on a few years ago I discovered a few valves had kissed the top of the pistons! No damage, fortunately. Make sure your gasket gives you the needed extra clearance and you have the heavier springs in.



I'm sure the cams available now are alot better.



The higher timing really improves the top end. I have a friend with a '98 auto and he loves his at about 21 or 22 degrees. He'll bump it up to that for a day at the track, but feels more comfortable for longevity and mileage at 18. 5 +/- for daily driving. I haven't run mine over the current 18. 5 to know how it would be. I'd probably not want to bring it back down either!



If your head is set up for it (studs) I'd certainly run it up to 18 - 19 degrees.
