Boost guage must have....but what are limits?

[bosljeff]

Sorry if this has been asked. I couldn't find the specific answer anywhere. Anyway, I know that one of the first things to upgrade is the boost guage especially as you modify boost levels. I know the factory guage is an "estimator". Okay, so I get the guage then modify the levels...what am I told besides what psi I'm hitting? Is it simply that I will accurately know the psi my engine melted, or is there some correlation with certain psi and certain impacts on the motor? Thanks for your help and sorry if I missed the answer somewhere else.

okay... i read that over like 30 times. So your questions are:
a) if you bump up the boost levels, what will the boost gauge read besides boost? if it reads vac then you will be told vac levels I guess

b) melted???

c) if you crank up the boost too much it's not the motor itself you will break (i am guessing you have a 14b)... the stock internals are pretty strong... you will max out your fuel system... and the turbo might get superhot and it could be damaged. also at high psi the stock IC will heatsoak in no time.

I'm sorry if those arent the questions you asked... i'm a smart guy and that's what I got from your post.

oh yeah it seems like this is not the right forum.

Thanks bro: you're right the wording of my post was similar to a schizophrenic monkey doing a math problem. Sorry. You kind of answered my questions. Forgive my "terminology" (i.e. melted), I was being sarcastic.

My question: I get a MBC and any other products that increase my boost and I am supposed to also get a boost guage. Right. So, I have all this additional psi and a new guage that now tells me accurately the amounts of boost I am getting. Very loosly speaking, is this simply for my edification, or what? I mean, I assume the knowledge of my increased psi is good to know when doing some type of diagnostic on my car (dyno, datalogging, whatever), but beyond that why is it so crucial to accurately tell how much boost you are running as you modify your car to get more boost? Can you use the guage to help you drive more efficiently (when to shift..., rate of acceleration...)? Is there some turbo troll that will simply kick my ass if I modify my boost without knowing how much boost I am actually getting?

By the way, I am getting a boost guage, but I just wanted to fully know all of its benefits. I am not trying to argue not getting one. Thanks again for your patience. Please believe me, I am beyond a newbie, but there is still some stuff (obviously) that I need help on.

Okay, done. Never again will I write anything this long.

it keeps you from hurting your motor. i'd run run 16psi max stock. the gauge is there just to tell you how high ur boost is!

Sorry to hassle, but beyond stock and the 16 psi, is there some common knowledge thing I am missing regarding what psi is okay only if certain mods have been done? Or am I just over-analyzing something simple?

Thanks

Yes you will need more mods to run higher boost, and yes you are over-analyzing something simple.
