I have a 2000 zx3 that is boosted by a stage 1 aerocharger. What psi should I run if im driving daily?

Wish I had a boosted daily....

I also have a zx5 svt, they are both great cars.

i think the aero set up has two boost settings its like 8 and 12........zurno would know he has/had that set up. but id run it at 8 psi cus its easier on the car.

Does this mean I should get it retuned aswell? Right now its running at 14, and can get up to 18psi lol

If your daily, the lower is probably the best. Just to keep it reliable, ya know?

Does it have a wideband?

It must be tuned well if you're hitting 18psi and not blowing up, makes me wonder if the bottom end has been done as well because I believe that's well above what a stock bottom end should hold.

Nothing has been done to the bottom end or at all internally. Somehow he's running 18psi without the car blowing up though.

how do you know how many bar? and 18 psi even on a 8:1 comp stocker is like running around with a pinless grenade and all the scissors pointy side up.

No kidding, It doesn't matter how well it's tuned. A stock Zetec won't hold 18psi for long.

I was under the impression that 12 or so was about it.

What is the weak point, the rods or the pistons?

at 18 psi..... rods,head gaskets,rings,valve seals

And your underwear when those fail...

Is your gauge inaccurate?
