Does your stock intercooler Leak ninja? I've been running twins for 3 yrs and have 58-62lbs of boost with zero issues still. I'd wait till it leaks personally.

I put a LML drivers side manifold on my truck. stock exhaust besides that b/c I felt the money could be used elsewhere. Not that I wouldn't put a good set on if I had the cash and I will be doing something for the race engine. But not needed until way down the road

I added an intercooler, and manifolds and pipes when I built my motor, which I am still doing. I have 3" y bridge already and 3" piping, I did it because I don't want to blow a hole in my intercooler, and I figured if it flows more air, and exhaust gases, then everything would be working more efficient.

no not yet, but its probably due..id rather replace it now before it blows

I believe the "real benefit" comes with the understanding that everything works as a whole, in the end, everything together makes up for the accumulative total.

If you're looking for bang for the buck mods, the intercooler isn't it. If you're looking to build something that you want to build to be badd, stand the test of time, something that doesn't leave you second guessing "what's gonna happen next" and is just as good or better than the factory, and is ready for what ever you plan next....then IMHO, you have to address damn near every part, and if that's what you want, then the intercooler, manifolds and uppipes and all the intercooler piping, an upgraded trans cooler and a few other key parts should all be in your sights...

i realize that all parts should be addressed...im just trying to get an idea of which ones work well in stock form at higher power levels and which ones dont? not trying to cut corners at all! just trying to get a realistic idea of what is working and whats not..whats problematic and whats not..

OEM exhaust works fine at mild built power levels. Lots of guys just throw a LML drivers side on and call it good for street builds. IC flow fine, but the OEM seems to let go somewhere above 50 PSI, your results will vary with that.

Ok, I get it and, well, I guess the point I was/am trying to make, is :

There's not one singular part that makes up for the losses or restriction that will make a significant or noticeable difference, you might do a IC hot side pipe and not notice much, maybe 50* drop in egt and a little more sound! same with the intercooler! same with the manifolds....as a singular upgrade

However, as a whole, if you went from the configuration you're in to a completely upgraded charge air and manifolds system, addressing everything as a whole, all at once you would notice a significant difference, probably 150*+ drop in egt across the board with slower spike, better throttle response, higher peak boost, better economy etc etc

But I really feel like it's not until everything as a whole is put in place that real benefits are evident, and why I believe most don't see one thing as a particularly worthwhile investment...
:thumb:

I can't say I'm unsatisfied with my set up, in fact I'm quite satisfied with everything, and feel like it's because I've gone to the lengths I have that my set up works soo well for me and why I'm so satisfied with my progress and how the truck runs, so personally I believe if you can do it, do it, addressing the system as a whole will benefit the overall outcome in most any configuration, so long as everything is properly thought out, I mean, you don't need a 5" custom intake, 3" IC piping an intercooler and manifolds to run stock trans efi live tuning, so consider your goals, or just buy everything you can for a nice street queen, really it's all about what you're looking for, some guys just wanna say, "hey man I've done everything" some guys specifically wanna make the most power for the smallest dollar, some guys are just scraping by getting what they can, some guys are slowly building up to reach big goals, what are you looking to do?

i agree that every little bit helps and looking at everything as a whole. but when I did my mani/up pipes, and also my IC I did not notice any difference. I bought them because I get a good deal and just wanted to try them. im sure that manifolds and up pipes help relieve drive pressure also but I don't have a gauge to watch that

Lol, your chit never breaks, I don't know how but you got the "honey badger" of the gm trucks:rofl:

This is how I think about it too, it's just good measure against future issues among other things

I enjoyed it! Lol

Really, I did notice a difference, not significant, but it's there, at least on my truck :dontknow:

COCOAL off the top of your head..quick guess what a mani' up pipes, and ic+piping would cost? I can do the research but didnt know if you had a rough number?

Holly heck, I'd guess you're looking at about $2600 minimum:rolleyes: add custom colors, or don't find everything on sale and add custom colors and $3000starts sounding low....

Aftermarket IC pipe, manifolds, up pipes, even an aftermarket intercooler? I see lots of guys have it done..but at what point in your build do you stop and say its time for this stuff..? At what point is it absolutely necessary?


Bd manifold and profab uppipes, and my stock heads made 973/1671. I am running 3" intercooler pipes....

Manifolds and uppipes when I got to the point where I was looking for every last bit of HP. Never considered larger boost tubes with the stock turbo. Stock intercooler was fine for my needs.

It seemed to work. ;)

I have stock manifolds/up pipes on my single cab and don't plan on upgrading them, or the intercooler. I saw zero change with manifolds/up pipes in a twin turbo application.

Lol, your chit never breaks, I don't know how but you got

I'd say it more knowing what it can and can't do. I'd say it's a lot to do with the driver. And I'd also say, there's tons making same Boost and alot higher hp then I and seem to last just fine.

All I'm sayin, no point for a intercooler unless it's leaking. Many have stockers yet. I think the way brian sounds, he to is running stockers.

And I'd agree with all you just said...

If I could do it over again, I wouldn't have spent the money at the time I did on the intercooler and manifolds, it would have been much more productive for me to have purchased something like a modded CP3 for a single or a dual fueler kit

Damn it if I don't have to say, you guys tried to caution me at the time, and I didn't listen

Hindsight...
or the ability to really listen to those who've gone before you and deny your desires for eye candy parts and truly seek out go fast parts...
Is always clearer

experience pays, and experience says the intercooler and manifolds are fine for most purposes for 850 hp and/or more...

Again, weigh your values and part with your money cautiously, I was hasty, and while again I am very satisfied with what I've got, it wouldn't be any different and possibly even better (keeping the stock manifolds) and putting those funds elsewhere....


Literally, knowledge is power...:joker:

Ya fass 150, 5/8 pickup, I'm already @ 55lbs of boost

I'd run that OEM intercooler till it pops. You aren't going to gain any real performance numbers from the upgrade, it will just hold up better bc it won't have plastic end tanks on it like the OEM one does...

You could buy a set of rods with that price list Coco mentioned. IMO if you need to spend money start getting build parts together. Spending a lot of money on parts with relatively little hp gained just to tiptoe a little closer to blowing it up doesn't make sense IMO. If you know it's coming plan for it. Now after the built motor, dual fueler, big injectors, turbo(s), by all means proceed with the extras. JMO
