Don't like Egt's after build

StrokiNDieseL · Nov 3, 2015

Put together like so, "re used" block machined/balenced w/standard coated/delipped Pistons on stock rods.
-cometic gasket kit
-stage1 cam
-side action lifters
-heads treated/flattened (no porting)
-springs/retainers,pushrods
-6.0 mani's- Hd uppipes w/provision
-WG dump to atmo
-bullseye Hp/Lp balanced wheel replacement *> ( I'M SURE THIS MY REASON DUE TO STOCK HOUSING?)
-newer HPFP w/30% 8-hole nozzles
-injectors flowed by Mpd
-Rcd ported intake
-No Limit Cai
-Alradco IC
-FTI TC, PTP shift sol in stock trans
-Arp's inside/out.

So I wasn't present for dyno run so IDK how hot it got but 50-75% throttle & I'm quickly at 1300-1750ish. Rcd intake w/IC & NoLimit but I'm guessing my issue has lead me back to me earlier research that the stock charger housing his my heat issue & would benefit from a compound replacement? Coated Pistons in there but cooler the better is the goal.. Suggestions anyone could add would be appreciated, thanks. Jayson

What does boost and backpressure look like?

StrokiNDieseL · Nov 3, 2015

Spools great, pretty close 1:1. Gate opens too early if you ask me but that's prob also due to stock charger housing? 50+boost I see & gate opens between 63-65ebp.

Normal hi way 45-80 is fine & see 475-700* depending on throttle so those have stayed cool since my Alradco IC. Just since wheel replacements I'm seeing the higher egts.

Did I read right you're running 30% nozzles on stock HPFP

getstroked27 · Nov 3, 2015

way too much fuel for stock chargers. wheels do not improve much of anything. also, another note, 30% nozzles on a stock single pump is basically pointless, you have to drop PW so far to be able to maintain RP that it negates most of the benefits of having more fuel. but like i said, added fuel on stock chargers is no bueno. that is a lot of boost from stock chargers as well. that is way outside of their efficiency map. So they are basically just forcing hot air, not making power, but losing power. that is why you are running so hot. throw dual pumps on it and bigger chargers.

Yep, newer replacement.

This right here. That's why I asked if I read that right....

Right on, thanks. GH revision runs better than canned but I'm sure that's due to somewhat of your explanation. Dual's/Lpfs are the plans for next mods to come.

Stock pump can barely keep up with stock nozzles, let alone larger ones. but that is besides the point, that is way too much fuel for stock turbos. and you are wayyyy over speeding those stock chargers. you need a second pump and moar turbo. or dial fuel way back and gate much lower.

Sounds like I should've skipped the wheel replacements & nozzles.. Would have been 1/2 way to dual pump$. Would you throw stock injectors back in for the right price or just manage it til dual pumps are on it?

You're out of air bud.

getstroked27 · Nov 3, 2015

nahh leave them in. just know your going to be running stupi hot until you get more air

Dual lpfp is not what "dual pumps" means...

Typo, Thanks. Lp system is needed either way but dual pumps are a must to maintain rail as I've experienced that on H&S mild tune b4 GH revision since these 30's been added.

Easier explanation here, I get that. Diesel is new to me but was wondering this due to all my air upgrades. But got confused when I see everyone saying they don't break 1200+*.

SEABEE08FX4 · Nov 4, 2015

High EGT's like that are common with the stock turbos, drop in wheel upgrades do little to curb that. Just can't move enough air to keep them in check. A larger low pressure turbo like a 71mm or larger would be a good upgrade in both power and egt control.

stock turbos only move so much air. the air upgrades you require are in the lung department...

So I wouldn't benefit from sending stock chargers to someone like Border, and best would be to buy like mentioned ^ about 71-2/59? Address dual fuellers 1st?
