I know that most people run an intercooler, and I know why.
is there a specific boost level that an intercooler becomes an absolute must have at?
or would I be safe running 5 psi, for example, without one?
and does the answer apply to all cars or just to maximas

You would probably be safe running 5 psi without an intercooler. In fact most kits like Greddy come without an intercooler, and are setup to run low boost, like 4 psi. With an intercooler though, you will make more power and be able to run more boost safely. It would be better to get all the piping done right the first time than to have to tear into the car again.

do we know a limit?
or will that vary by the turbo and engine displacement

A limit of what? How much boost a Maxima can hold? How much more boost a turbo application will make AFTER an IC?

Of course there IS a limit, but to what caliber? Boost controllers are a key factor too, (besides turbo/engine displacement)

If I were you, and I just had to run the max amount of boost w/o an IC, I would slowly increase boost until I noticed signs of detonation, or the ECU starts pulling timing, then go back 1 PSI. The limit depends on a lot of things, turbo efficiency, CR, maybe even weather/outside temps.

a limit as to the maximum safe amount of boost without an intercooler

I don't have to run the maximum amount of boost, I am just trying to figure out if my plans will need an IC or not
BTW I won't have an ECU

IMO, if running you are having the intercooler/no intercooler debate then you should reconsider going turbo. It is just a no brainer and not that much more expensive. You don't have to spend $500 on a spearco bar and platel. Having a $150 SSautochrome ebay intercooler is better than non.

Again, IMO if your not gonna do it right then don't do it.

burtreynolds

hell you can get a sidemount from a stock DSM or supra for like 40 bux or stock FMIC from a SAAB for cheap if $$$ is the issue. I really can't imagine having a setup that includes a standalone and then skipping an intercooler, just doesn't make sense but I dont know your plans so...

I'm considering getting the 2 intercoolers off a z32TT or if I can find one later, greddy makes a 2 inlet 1 outlet IC.
But I'm noit 100% sure this app needs one.
I didn't notice one on the Banks systems.

BTW I do appreciatte the advice. I'm just not thrilled with the thought of more piping and trying to find space for an intercooler

by what you said are you using a carb if you are ive heard that since the fuel is entering at the top of the intake manifold it has more time to cool the charge air kind of like water injection and will let you run more boost without an intercooler

if thats the case you could proboly run 10psi without an intercooler

let us know what car this is for

I'm trying to keep computers out of it as much as possible.

are you supercharging it or turbo? a turbo is almost always nescasary to have an intercooler because it makes much warmer air. if its a supercharger then i wouldnt worry about it.

The banks systems don't run much boost. I betcha they are only doing 5 PSI. I mean their "crate" motor makes just of 600HP. That sounds like 5PSI range to me on 3-400 ci engines.
