im a noob with diesels so be patient with me please!

I live in WI, only tow my fifthwheel from time to time. i have a 97 f-250HD 7.3 PS. bone stock except for air box delete and unplugged EGPV.

Questions:
-whats the max boost i can get out of my stock factory guarett turbo without upgrading it?

-do i need to intercool my truck if i pull my fifthwheel short distances from time to time, more of flat terrain?

-3 inch down-pipe and 4 inch DP back? What hp/tq levels can i achieve with this? i got stock everything right now?

- cheap but good guages and links to them?
i was thinking: Pyro (EGT), tranny temp & boost... is that a good set up?

-im not looking to build a monster... i just want at least 600ft/lbs eventually...maybe 400 horses? i want to do the cheap first and work my way up...
that being said... when should i stud my heads?

-My egpv is engaging after its warmed going down the road, i disconnect it but i think i read someplace it can leak oil into your intake...is this true? if so how do i remove it completely? delete kit done right? or is it worth fixing?

Thanks guys for the help!

 

Max boost and max SUSTAINABLE boost are two different animals. I don't want to tell you something wrong so I will skip that one.

Intercool? If you have stock injectors, chances are you don't need to intercool but that could be seen for certain once you get an EGT gauge. If you are pushing past 1250F while accelerating or cruising, an intercooler would be vital to your engine's survival. If not, it is always a nice preventative upgrade for later (with those HP/TQ numbers you're gonna need a large and in charge IC)

As far as actual HP gains with the new exhaust, IDK if there is even a number... If there is, I haven't seen it. I did however see a slight drop in EGT when I opened up my intake and exhaust compared to stock.

I run Glow Shift Trans, boost, EGT, and Fuel pressure and have been very happy with them. Just be very very careful while installing the fuel pressure sender since you can crack your FPR and that is a bad day. Use locktite or another liquid thread locker, not teflon tape.

I think the limit on stock head studs is something like 45 psi of boost? Maybe I made that up. Long story short, it is like the IC, it will be a preventative upgrade you'll have to do anyway if you really want to get to the goals you mentioned. As I am sure the guys that currently run those numbers will tell you, it is a lot of money and a lot of time to make one of these trucks run reliably at those numbers.

I would delete that EBPV instead of trying to fix it unless you are wanting to wire it in as an exhaust brake. It's more of a leak point than a useful item in my opinion.

I hope that shed some light on your questions. If you have spare time, take a look at those stickies on the top of the thread list and read away. You will learn stuff you didn't even know you needed to know.

 

You will need bigger injectors to get the HP/TQ numbers you ask for. You won't have to go huge or anything, but the factory sticks will not make those numbers for you. You may need a bigger HPOP, definitely bigger exhaust, and you already have an intake. The tranny will need to be upgraded if it's an automatic, I can guarantee it.

Also, if you plan to make those numbers while towing your 5th wheel, you will definitely need a bigger turbo and I.C., and even then, don't know if you can maintain that going up a hill or mountain. But if you're running a factory automatic transmission, it probably won't let any damage come to the motor as the transmission will likely fail before you get it that hot.

This guy had a lot of the same questions. His thread is worth a read.

 

I have a question for you, do you know what a 400HP 7.3 truck runs like?

If your truck is bone stock, a good TS Chip or Hydra may be all you need/want. Just make sure everything on the truck is in good shape, no exhaust leaks at the up-pipes, manifolds, or turbo. Good intake and exhaust, (BTW, don't expect any HP/TQ gains with the intake and exhaust mods. Those just set you up for other performance mods like a chip and injectors.)

Some people think they can get their 7.3's to pull like the new 6.7's or even the 6.4's. Well, they won't, at least not for any length of time. You certainly can make them run better, but they won't beat the new trucks.

 

Read the signatures of guys who post, lots of info there.

 

I'm not trying to be a smarta$$ by any means, but my advice to you would be get the truck running and mechanically sound with no issues before you even think about doing any power upgrades.

 

And Read-Read-Read-search-Read some more..

 

Ive done a lot of the upgrades yet its still mostly stock. it fent the same. I put a chip in it and then i had more power. in the end i was happy with the power pulling my 24' toy hauler full of 4x4 quads and 2 more on the back of my truck. pulls at 75 mph with ease.

 

Uh yup....mechanically sound means everything and mods mean nothing. Get the truck running right first and foremost.

 

about 6 months before starting a thread to study and learn seems fair..read,read,read..ALL the info younneed is here if you look and read.we are NOT breaking any new ground on these 20 year old powerplants...

 

I agree. 12 years ago I didn't know what a sticky was! lol

 

never mind no worth a pissing contest

 

whats an hpop. i already planned on making it mechanically sound first. but i have stock original injectors (i figure) and they sooner or later will get worse. my judge of power is this: if i can put it down to the floor and it spins tires for a decent length on dry pavement...then its got plenty of power. i cannot do this now. my wheels do not break free, but i do know i have manifold and down pipe leaks. i will start working on exaust after i do the following: my front end steering and 4wd cccomponents(u joints, tie rod ends, saggy leafs fixed, ball joints, alignment...etc) fixed. then im going fix my cold no start issue (gpr, ucvh, gp's) and then finally work on exaust. replace any leaky gaskets too somewhere in here. after exaust then i will get guages. then i will do the injectors and chip. (Do you have links to a decent size injector and chip kit? i like those ones with the switch that goes under your dash to turn up or down the fuel)
At that point if im not happy i will go further.
are there any turbo upgrades i should do too? blow off or wastegate...etc?

where do i find the ebpv delete kit?

thank you for being patient and for answering my questions!

Chip, many factors, some are cheap to reprogram and others not so much


You need to decide on how much power you want to determine the stix and turbo upgrade


Diesels don't have a ton of HP at low RPM, they make it around 2k or so
