Close to pulling trigger in A&A- have question on lowered car
#21
Wow, your boost is really up there. What pulley are you using? I am going back and forth between buying the 3.8 or 3.6. My 99 has a stock motor, but does have LS6 intake, headers, cats still on, cat back exhaust and 3200 stall converter...I was trying to stay around 10 psi max and even a tad lower...I know it may be 7 to 9 psi with the 3.8 and 10 or 11 psi with the 3.6, but that's a guess
Before the longtubes with shorties and stock cats the 3.6 pulley made 8 psi but
it dropped to 6 after the longtubes.

I am confused as to why it boost would be that low. This is the lowest that I have heard. I assume you do not have a stock engine....Do you? mods??

you also have to take into account how high the car is being revved... if they are cutting the rpms short, say 5500, then that will also explain the boost seeming low... rap it out to 6500+ and then you may see the 10-12psi you want... the impeller speed will also make a difference, for example you could use an overdrive balancer to turn the blower harder and make a higher boost number than you would with the same blower pulley and stock balancer with both being revved to the same rpm

Boost is a measure of restriction.
I'm happy with it.
Quick like a bike and breaks the tires loose in 3rd gear (M6)

Front view, all I do is scrape the black parts on speed bumps. Lowered on stock bolts and Hotchkis bars front and rear. I have no issues with clearance and have Kooks longtubs.
Apologies for the long wait.

Perfect, when you say black parts are you referring to the plastic air dams that hang down and not the metal fangs(which is part of the support that was lowered for the SC install)???? I really appreciate the pics

yup, the plastic air dams, sounds awful when they scrape in the car but hasn't amounted to as anything. One thing to keep an eye on though is how much debris you pick up in the radiator. Every year around fall when the leaves come down I get more than a few up there, I also found a dead finch few years back.
