Boost

[case340]

Hey y'all, I unplugged that red wire off the wastegate, and I'm hitting 30-34 pounds of boost on stock turbo, stock injectors, and wildman tunes. Is it okay to run that much boost on the turbo??

not really
i think it loses efficiency after 28 lbs of boost.

My truck boosts that high with the line installed.I just seem to blow intercooler boots off.I since have ordered better ones.My truck used to spool about 25 psi at its highest with a 38r turbo.But I never adjusted my wastegate until recently and now she runs like a scalled dog.It will boost 30+ right now.My truck likes the boost!But dont overdo it because the motor will eventually get mad at you and puke.

clean the intercooler pipes good too.
also if you keep blowing boots off spray some white rain hairspray on the inside of the boot when you slip them back on. this will help hold them

these trucks dont usually have head gasket issues.
40+ lbs of boost is when you get some problems.

See idk why it's pushing so much on the stock turbo I guess cuz it's a standard I can hold it there longer and get alittle more out of it?

I had that problem blowing off boots between my turbo and intercooler. They used the stock, blue ford ones...they're no good with a 38r. Went from pushin 38-39lbs to 48-49lbs. Need to back it off...no mods and powdered-metal rods.

Boost doesn't kill engines...

You're pushing close to 50 pounds of boost, on stock injectors, with a 38R?

[jays big blue]

yup. Boost might not kill an engine...blowin a head gasket or stud is pretty likely though.

That type of boost will kill the stock turbo pretty quickly tho. dont be surprised if you hear it pop soon.

And the guy running 50psi on stock injectors, there is something wrong there. Even with 250s I have yet to see over 40...

Haha i plugged the red wire back on, the truck is for sale now and don't want to mess anything up
