Turning up the boost!

[xi Talon ix]

I have a completely stock 1990 Eagle Talon TSi AWD and I'm not saying that I am going to do it but if I planned on it in the future. Would I be able to turn the boost up to 10 lbs without harming my engine. Or would I have to get injectors, fuel pump and all that good shit. Just let me know guys.

10 psi is the stock setting. Are you using the factory gauge to measure boost?

Yea my guage is reading 8 lbs now. So what is a good setting on a stock engine.

Ohhh for shame for shame. Back to basics for you my friend. Trust us on this:

READ THE BASIC ARTICLES!!!

With that said, 10lbs is correct for a baseline on a stock car, but as ALWAYS, don't trust that stock boost gauge. Especially when starting to mod your car. Get an aftermarket one (boost gauge), and THEN set your boost controller at 10 psi. Make sure to do a boost leak test first, though!!

The stock boost gauge does not read boost, it's merely a calculated amount based on what the ecu sees from the air sensor and should not be seen as an accurate reading of how much boost your engine is really pushing.

Follow this Upgrade Path on getting some power out of your car, but make sure your engine is in tip-top shape (proper tuneup) before you do any of these steps.

you should be able to boost up to 16psi on a stock fuel system past that and u need more supporting fuel mods-FPR,Injectors,fuel pump

While this may be workable on SOME cars it doesn't mean it's universal for ALL cars and is therefore not solid advice. You should log the car and look for knock as a determining factor in how much boost can safely be run on stock fuel. Fuel pump and injector health will have a large part to play in how much a motor will tolerate before it knocks.
