b4 boost

[ohbev]

Friend has a 02 b4 twin turbo.

The car is stock we just fitted a boost gauge. In 4th gear if i put my foot flat at like 2000rpm and let the car start boosting the boost go's to 16psi
In second gear it go's to 10-11psi should the car be going to 16psi in 4th or is that to high ?

What is the stock 02 b4's boost in 4th ?

That's close to what my 02 B4 boosts at. Mine peaks at 15psi primary in forth then drops to 10-12 sequential.
Stock exept for a K&N air filter.

Not sure about second but I'll get back to you.

Second peaks at about 13psi then drops back to 10-11.

As for you question about the stock boost, From what ive read on other forums B4's all boost differently because of the complicated setup.

Id tell you mate not to worry and just enjoy.

Which lines did you tap into for the boost gauge?

Im installing a boost gauge but unsure which vacuum lines to use.

There are 3 lines coming out of the inlet manifold just above the red cap on the alternator. Tap into the one on the left, it no.8 if i remember correctly.

Chop a coat hanger and tape it to the BG pressure line when poking it through the firewall, it helps alot.
