Sliding stock fuel plate forward CTD

I've been planning on sliding the stock fuel plate full forward in my 96 CTD. I know a few of ya have done it and im just curious how much of a power gain it will actually give me. Thanks

I am With Stupid
Yeah, Iv'e been pondering this as well. I too would like to know how much of a power gain one can get out of just budging it forward a bit. It can't be that much but I am sure it is enough to give a noticeable difference.

I'd imagine if you also helped with the intake (more air) you would notice something. If you don't help intake and exhaust then maybe a bit but get some nice black soot comming out the pipe.

I've already taken care of the air issue, that Banks Twin Ram manifold flows a bunch more air than the stock single ram. I think I should be able to move the plate all the way forward and get all kinds of power, but how much?? Dunno One only knows.

I did it, it didn't do as much as I thought, I also pinched off the boost line to the wastegate, and it used to be 18 PSI stock, and now it goes almost to 30psi. I read somewhere on DTR or TDR that you can even take the plate out and control the fuel curve with your right foot, some people said its a bad Idea, and others said they had it like that for 100,000 miles with no problems.

I would not recommend removing the fuel plate. You can run a flat plate that is basically a rack stop so as not to damage the pump.

HP from sliding the plate depends on a few things. What pump the truck has and other mods. On a stock 1996 with the stock 180 pump sliding the plate will yield around 15-20HP. On a 215 pump 1n a 1996 manual transmisison truck sliding the plate will yield more HP.

jgk,
I would imagine on your truck sliding the plate will yield a few more HP than 15-20.

EGT's will increase so if you do any heavy towing and do not have an EGT gauge I would not recommend sliding the plate.

Personally I prefer an aftermarket cam plate vs. sliding a stock plate. It has more affect on the drivability and HP of the truck. I run my aftermarket plate full forward Very Happy

Yeah, I have a EGT gauge, so covered there.

FireRescue, what else did you do to the pump besides moving the plate all the way forward?? I know you probably mentioned this in the old forum of "Turning up the fuel", but I thought I would ask again. Is your boost line pinched off as well? Can't be sure but isn't pinching that line off potentally dangerous for the life of the turbo??

I have advanced the timing, adjusted the AFC star wheel and installed an AFC spring kit, installed high flow delivery valves, installed a TST plate full forward, adjusted the governor lever, and installed a 3k Governor Spring Kit. Nothing real special. I would like to take it off an have some real pump work done. Maybe someday Very Happy

For the governor lever adjustment check Piers Diesel Research here: http://www.piersdiesel.com/TechLeverAdj.htm

My boost line isn't pinched. I have too much fuel to not wastegate the turbo because, as you alluded to, there is a limit to the boost pressure of a turbo. An HX35 in stock trim should be limited to 36-38 psi of boost. Beyond that the turbo has exceeded it's efficiency range and you are doing nothing but moving hot air. You could actually increase the EGT's by exceeding the efficiency range of a turbo. Not to mention you also risk damage of the turbo although the HX35 is pretty durable beyond that. You can run low to mid 40's for boost on the 35 without too much worry of blowing it up, not that I would recommend this Very Happy Some other turbos, like the HX40, should definitely not be run out of their efficiency range as they are not quite as stable as the HX35.

Man, I wonder if I have a boost leak, cuz I heard that those turbos will put out a max of 22 psi with all the OEM stuff on the engine and turbo. I never hooked up my boost gauge while it was stock but when I pin it going up a hill in 4th or 5th gear, the highest boost I have seen on my gauge is like 36 psi. I haven't asked Banks what I should be seeing, but I think I am going to now, this is making me curious.
Also, which way did you turn your AFC star wheel and how many turns are recommended? I know it controls the pre-boost fuel but can you turn the wheel too much with the plate all the way forward and cause problems??

Considering its nearly 2am I'm just gonna state some facts then I'll come back tomorrow and re-read this and make a more detailed reply.

Sliding the plate from center to full forward on a 5spd truck will net you 40HP @ the rear wheels. I've seen it dyno proven! Check my sig as well!

HOWEVER! I do NOT advise sliding the plate without a Exhaust Gas Temp. gauge PRE-turbo.

JKG....your banks twin ram may flow more air....but your still limited to your restrictive air box if you haven't upgraded to something like a BHAF (big honkin air filter), AFE/Mega Cannon, or Scotty II. So your not gonna get the EGT reduction needed to cover the extra fuel.

Like I said. I'm tired right now and I have a TDR meeting @ 10am in the morning in Nashville. I'll come back and re-read this post tomorrow and make a more detailed reply. I hope no offense is taken from this post, none is certianly intended.

Now I'm going to bed! ROTFL
