For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Pulling vacuum up top, intake, exhaust or both?

Post  docwyte on Sat Mar 31, 2012 3:53 pm

Setup is a 2002 LS1 motor installed in my Porsche 944.

Stock LS1 MAF, ported stock LS1 throttle body, LS6 intake manifold. Stock motor, EPS 226/230 cam, 1 5/8" primary mid length headers, no cats, dual 2.5" exhaust with an X pipe and a single 18" Magnaflow exhaust.

I'm pulling a pretty strong vacuum up top with my current setup With HP Tuners it's dropping from 82 (I'm at altitude in Denver, CO) to 77.

Tuner has suggested I go to a LS2 MAF/throttle body first, then to a larger set of headers. Eric does make a 1 3/4" primary long tube headers for my swap, but have to redo a bit of my exhaust downstream to make them fit.

I'd prefer to address the intake first as it's cheaper/easier to do. Do you guys think this theory is on the right track?
