SmokinFive9 4x4

I bought my injection pump used and was told when I did that it had a custom ground fuel plate. I haven't personally taken it out to look at it, or see if its just the stock one adjusted forward. What I do know is that the truck makes about 40psi of boost, but has wicked EGT's. If I stay on in long it climbs like lightning past 1500. Within a few seconds even.
Another thread about the 3k springs convinced me that might be a good thing to get, but I'm sure even when I did that I could never see 2800rpms because I couldn't hold the pedal down that long. The truck runs great, puts out loads of power for about 10 seconds, but I can't keep on it that long for fear of melting something. So while I'm tinkering with the springs, I'm thinking since I've heard so many people rave about their #10 plate I'd pick one of those up and see if that won't help lower the EGT's. But I don't want to lose any power, obviously. I do plan on getting the delivery valves done sometime soon, within a couple months, so I wonder how it would react to that. I do have the 96 215hp pump. I'm just looking for a way to lower the EGTS and get some more usable power out of it. I don't even like pulls with it, just a few seconds too long in the high end of the pyro for my comfort.
Take a look at my signature for the mods to my truck. Any thoughts on how a #10 might affect it? I know its difficult not knowing what plate it has now, but in my mind a "custom ground" plate shouldn't be burning that hot should it?

Different turbo, slidin the fuel plate back, 4 inch straight pipe.

Which turbo? I have an hx40, 14mm housing. If I buy another I might as well go twins The truck now has a 4" pipe w/ a straight through muffler to 5" stacks, that didn't affect anything as far as EGT's go. The plate I think I'm going to take out and take a picture of it sometime soon, hopefully someone may be able to identify it? Also see where it's at as far as full forward or what. Like I said I really don't want to lose power. I'm not sure what kind of hp other trucks are making but I can't imagine I'm over the limit where EGT's can stay civil. How's a #10 as far as EGT's go?

Yeah sorry bout that.I had just came in from the shop and I didn't read the whole post, my bad.

I sure like your reasoning.

Did the 40 ever have a 16 housing? No doubt that'd keep it cooler. There's lots of guys running an HX40-16, #10 & 370's with a 215 pump. That combo isn't too hot, so maybe it's the 14?

I dunno, I'll have to check into it, might help. Another question, timing. I see alot of people advanced to 17* That help with egt's? power? That's one thing I never messed with, kinda scared to lol. Something someone can do themselves? I have tools, that's no problem. How simple is it to do, or is it at all?

Thanks,
Ian

There are some special tools needed ... I haven't done it. I noticed that advancing took away the low end power & moved it to the high end. It might have an effect on egt too, didn't really look that close. Try searching on it & the tools will pop up.

Well looks like I'll be buying some more tools lol. Is there another setting that doesn't compromise low end as much? Or is kindof a shot in the dark just trial and error that gets you where you want to be?

Forrest

You might do just that ... start @ 15.5, see what you think & then try something more.

I tow the 5'er & the loss of low end isn't an issue. No downside there. The up side is the loss of low end is MUCH easier on the tires.

Eh. I'm not easy on tires anyways Check out my gallery, a couple weeks ago a guy at work (he has a 68 Nova with a built 355, tubbed, rollcage, whole race car deal, runs 11's.) challenged me to a burnout contest. HE NEEDED WATER!? can you believe some people? water, pssh.
