Default How much boost are you guys running?

Just wondering how much most of you guys are running. I might go turbo down the line after my warranty runs out. Thanks for any info given!

8 psi on 93 octane and 10 psi on 95+ octane, and as high as 14 psi with a little timing retard added in, before my IC started to leak.

Now with this pressure leak and the boost controller turned all the way up I only get 8 psi in 1st gear, 9 psi in 2nd-3rd, 10 psi in 4th, and up to 12 psi in 5th after a while on the gas to get it to creep up. New air/water IC is on order.

Larry

PS: This is at 6,000 feet where we can run 25-40% more boost.

Oh yeah, definitely. It's just proven to me more that I need to complete my plans rather then turning back.

I am running 6psi but I am finishing putting in my new clutch today and then my next investment is injectors so I can up the boost.

Stock internals can handle 22psi, but then the rods start to bend as seen on Adam Bloom's car.That is the highest boost i have heard of on a stock motor. So don't be shy guys just make sure you tune it properly for the higher amount of boost.

HUH? I don't think that's entirely true... Actually I'm pretty sure the pistons would be toast running that much boost, I've seen WRX pistons go at less than that.

7# getting new injectors and engine management, I should be able to crank it up a few notches, since I have a pretty well built motor.

KCZ : since when you moved to garland ? I'd say you can go 14 psi + with injectors easily since you got pistons and rods.

stock internals can take 12 psi NO problem with proper tuning , as long as you don't detonate , your internals will be fine. been done by many people.

I started out at 5psi w/no intercooler (in winter), then eventually added an IC and another 7psi along the way. The last month or so I was running 12psi with no problems. I even ran up to 13psi at the track without an issue. I chalk it up to tuning. A few guys have done blowed up their motors with 4psi or so, but if you look at the folks who have their cars tuned right the burnt pistons and bent rods are few and far between.

I am running 4 psi right now. I am waiting for my EGT probe for the 2nd week or so from autometer. I dont trust my a/f gauge, so I am not going any higher than 4 until I see some temps.
