Just wondering how many psi can you go up to with a ls motor and what is the highest safe psi.. 8? 10? 12? Just wondering. Let me know.

Damn do some research and stop making threads

It's not psi, it's the amount of Hp, 300whp is a safe number. Much more on pump and it wont last long

No one can answer your question because it varies with what turbo your using. For example 15lb of boost on a gt30 is different from 15lb on a gt40. And most important thing is your tune.

Lol stop trying to blow that poor motor already. Ship it to me ill take care. Of it.
And if you don't know much about motors stop working on em. Your just gonna spend more mooney plus your own time. Unless you think your time isn't worth much. My times worth 35 an hour I wouldn't waste that working on things I have no clue about..

Im on 10lbs as of last night that thread answered your question verbatim, welcome to HT but caution before you make a new thread people are quick to jump especially if you haven't put the time into clicking on the search bar. Use it and yes use it a lot man you will realize there are 1234e32 other people that usually have the same question.

Yes especially this guy who keeps making threads everyday asking simple questions that have been answered thousands of times

Use the search for simple questions. PSI mean nothing. 300whp is safe for a stock B series if the motor is in good shape.

Depending on fuel.. I would push a b well into 400' s on e85

This is a great way to blow up a motor.

yungkhmer

I have the same turbo but was reluctant to use it on my LS. Mind sharing your build? i heard i would have alot of lag with my setup. b20z block arp rod bolts b18b1 head with crower cams and valvetrain gsr tranny.

and YES i was kidding about my post but i actually do have buddys running 14lbs with 450's,walbro 255 and a street tune running for months... so far.. lol

fukenboostin

buddy had an auto LS 96 teg back in like 02, drag turbo kit t3/t04e 57 trim, 440 rc's, walbro 255, missing link with like 8 check valves and a SAFC street tuned to 12-13 psi. car ran 14.0 flat @101 on all seasons lolll
car ran for 3yrs before he did lsvtec, 5spd

Hahaha good to hear. I don't doubt you have a buddy running 14lbs at all actually. Just from your first post it seemed like you didn't know anything. Glad you proved me wrong.

I call bull **** Im running 17psi and running 880cc Precision Injectors and they are at almost a 85% duty cycle. so how are you supporting 14psi with 450cc injectors? what turbo on what motor?

I usually start at about 30psi and when you twist the vtec spool valve it increases your boost but make sure you have adequate fuel! 3000cc should suffice cuz bigger is better! and you need to run a colder plug so make sure you put the spark plugs in the freezer for 30-40 min before you tune on the dyno and you should be safe and with a few over night parts from japan your car with desimate all! SEARCH!!

yungkhmer

go ahead call bullshit. its all about the tune and uh hello it was a just a single cam with a homemade turbo setup. but i guess thats bullshit in your eyes. ever heard of realhomemadeturbo.com? probably not. running 14lbs with 450's is nothing new. sorry not everyone is so big black baller like you.
