VE Swapped 24v Timing/Tuning
Ever since I finished my ve pump 24v I've been running into issues with what I believe to be higher EGT than normal. Mostly during WOT pulls maxing out my gauge at 1600F, but also cruising at high speed on the highway (~80mph). I have everything done to my pump that I know of besides getting a bigger pump and timing spacer (ratman fuel screw, fuel pin, full cut DV, clipped 3800 spring). Im running dynomite diesel 125hp injectors popped at VE pop pressure. They picked that injector because that matches the flow of their stage 1 ve 12v injector if i remember correctly. Turbo is an he351 with a 67/76 turbine wheel/bigger housing and stock compressor wheel. I installed the larger turbine wheel and housing to battle high EGT but it had almost zero affect on it. The truck doesn't really even smoke that much unless I floor it below 1500rpm (nv4500). WOT pulls leave a gray haze behind me but definitely doesn't leave a black cloud. Normal driving it really doesn't smoke at all. I have the fuel pin all turned out as much as possible for lowest base fueling and same with the starwheel(high preload), requiring boost to build before it starts to add fuel. When the engine was out of the truck i set my timing to 16 degrees with an indicator and even though I have removed the pump multiple times since then believe the timing to still be around there. Point of this post is, after much research I found a user (ScreaminDieselPulling) on one of the forums claiming 26 degrees static timing on the same sort of setup completely changed the EGT during pulls from 1500F by 5th gear to being able to complete a full 1/4 mile at 1100-1200F. As well as dropping cruise EGT from 650-700F to 400-500F. So, I am going to slowly attempt his recipe and report back on whether or not this is viable. I probably won't go all the way to 26deg as it feels excessive for my daily driver, but 20-22 may be in the books for me. I don't have an upgraded HG or Bolts/Studs so if I am about to be in a world of hurt please let me know. Or, if anybody has some applicable experience let me know because there is very little info on timing VE swapped 24v trucks that I can find. Am also curious about whether or not the timing spacer would be a better idea to give a better drivability.

@Robert Winkworth 1. I bought the fass kit for the VE pump year trucks, so hypothetically 100GPH @ 8-10psi 2. Whatever camshaft cam stock in a 2001 truck with an automatic. 3. Stock he351cw compressor wheel should be 60x86 I gave it a small bump last night and she definitely has a bit more pep in her step, so ill try to get a measurement on it and then adjust from there. EGT are down a little but I can still easily get up to 1500F just rolling into 4th gear. Good to know I was nowhere near what I could be running for timing.

@Robert Winkworth also, are you saying the turbine size is a bit small?
He351 on a ve
Does anyone have first or second hand experience putting an he351 on a ve truck? Curious on your thoughts

I have one on my ve swapped 24v and it feels great. Spools fast and I’ve hit over 40 psi before
24valve ve swap
Alright this is what I've got so far I've turned up the fuel screw I've played with the timing right now it's set to one past c I'm running stock injectors what do y'all think my issue is has throttle response but won't idle after giving it throttle and if I don't touch the throttle it will idle but almost dies then picks back up a little bit

You might need more timing, need to get an indicator on it and get the exact timing on tdc. With the stock injectors the pop pressure is going to retard the timing a good amount. I had dynomite diesel send me a set of 125hp 24v injectors popped at the ve pop pressure. My timing is set at 16° but you may need more with the stock injectors like I said. Another huge issue I had was my delivery valves were rusty and sticking together. After I removed them and lightly cleaned them with a 3m it would run a lot better. Before I found that I was changing intermittent no start and doing everything under the sun because I thought it wasn’t fueling enough. So definitely check those to and make sure they’re in good condition.
Valve seat crack
Was cleaning up my buddies 12v head and noticed a crack between the valves on cylinder one, and the injector hole to the intake valve on 1/2. Crack went into the seat on intake 1. Anybody know if it’s alright to run it like this? Goal is 350-450 hp.

@Robert Winkworth agh I figured as much. Gunna go flip a coin. Thank you

@Robert Winkworth ordered my eBay head will be here mid next week, is the valve cover and intake surface flat enough to put on some 123 blocks to check flatness. I know it’s overkill but my straight edge is only 24”.
Replacement VE pump woodruff key
Hey everybody. Accidentally destroyed my woodruff key in my VE pump. Luckily nothing bad happened. But I found a replacement at ace hardware near me that worked and thought I’d share the dimensions of it in case somebody else wanted to snag some.
