So, my fuel economy dropped markedly; I noticed exhaust smoke and could smell fuel, aka I've got at least one bad injector. Long story short, I've spent a few days looking at turbo/compressor maps, nozzle flows in ml/min, and total fuel vs. air, and I just fell down the rabbit hole.
What does any average person do as I am starting to look at upgrading everything.
The truck is 2017 with a 5" exhaust, S&B intake, RaceME, and ARP studs.
Daily driver, but I do tow/haul monthly.
We are looking to make around 800HP and keep EGTs low while towing.
So far, I've come up with this list, and any advice/feedback is appreciated:
165gph lift pump, Exergy 12mm stroked CP3, Exergy 150 or 200% over injectors, replace the stock Holset with a drop in BD screamer 64mm turbo, S480 atmospheric turbo (was looking at the Pusher high mount compound turbo system), Hamilton springs and pushrods, and then a custom tune to tie it all in.
I am debating o-rings and a head gasket; I've heard fire rings get eaten over time, 100k miles or so, but not sure if either is necessary.
I like my exhaust brake, so I was looking at the screamer.
I know 150% over injectors will do the trick, I think 100% may be running too close to complete the duty cycle, but the 200% leaves room for more air in the future without being too large for the 64mm/S480 compound setup.
I baby my 68RFE, never push hard above 4th, and even then, I try to ensure the converter is locked before I put my foot down.
I know it won't last, and I've budgeted a trans and converter replacement for 2023.
I have 295/70/R18s, so I'm not actively trying to grenade the trans with 38's.
If I go all in, I want to do it right, and I want to do it once, so thanks for any advice.
Also, in watching a few videos, it seems no one wants to pull the front right quarter panel for ease of access to the turbos & exhaust.
Am I missing something here?
