Thread: How Much should a 3" produce

I have just bought this car and it has a 3" pulley. I just installed a boost gauge and it reads 10 psi at wot. Should It make more? I will put the list of wht was said to be done to the car.

odd you can run that any only see 10 psi with just rockers and headers.

Or the blower has been hookered.

It's showing vacuum of 30 is that high I thought 20 was the average correct??

And hookerd is??

Ah, I'd venture to guess your gauge is defective.

Hookered meaning opened up too much.

If you're not seeing KR, your AFR is in the low 11's and you're running at least 15* of timing, I wouldn't worry about it.

Ok it has just a cheap boost gauge and I got a aeroforce gauge ;-) but didn't really kno what to look for I had it on kr and o the whole time
I think the boost gauge is messed up Cause the aeroforce is showing -9
On manifold psi and the vac gauge is showing 28-30

Arf is?? And I need to look for the timing to be at 15*. I am new to all the numbers of all this. But I think the timing said 23 or something

That's Wht i was looking to hear!!!!
Wouldnt it show more boost and why is it not showing kr ?

have the aero set to KR and map then go for a nice series of second gear pulls.

See if you see any KR and what the aero says your boost is.

Then change the KR or boost to timing advance and see what thats like while going full throttle.

AFR is your air to fuel ratio.

With a ZZP PCM I'd think it'd be setup to run nicely.

Shouldn't a ZZP be closer to 11?
