No, all I'm saying is there seems to be a lot of fuss over this and some things I have seen floating about simply don't add up mathematically. It takes boost to make high off-idle and low RPM torque numbers and there is only one style of pump that does that!

Also, someone was asking about my turbochargers a while back...they are GT2871Rs with 0.86 a/r turbine housings. They are not GT28RS (aka Disco Potato) or GT2860...those have MUCH smaller compressors. Each one of the 2871Rs are rated to over 400 HP, in fact these exact turbos have supported 400 WHP on 4-cylinder builds in the past. The match to the 928 engine could not have been better...they are not jumpy, but they are there when you need them to be. The car generates full manifold pressure on just partial throttle and load yet flows out upstairs too! These are the same exact turbochargers used in the Lingenfelter twin turbo 5.7 liter Corvette. Lingenfelter has layed down 700 WHP with these exact turbochargers mounted to the Corvette.

Here is a good read on comparisons on different boost methods. Granted in this case the Turbo car shows up way ahead because of a better long runner intake manifold, but it's good to read nonetheless. Of significance is the difference in what the boost curves look like between all three styles of compressors. The boost curves tell a lot about what really happens.

I think a lot of automotive products confuse things, too much focus on dyno sheets and things that are easy to advertise, what counts is how a car feels when you drive it, and what happens a few years down the road when something breaks. Only time will tell whats good and whats gooder.

John,

You might want to think about submitting an article to autobahndreamingMAG.com . It is a Porsche tuning e-mag that has comitted to featuring a 928 in each issue. They already featured one of Tom Falkenburg's cars in their first issue and are planning on a piece about 928's open road racing in the next. Send an email to AutobahnAmbition@gmail.com and let them know what you are doing. I think it would be good press.

Thanks 421. I actually already contacted them. I think mine is slated to go into issue 3.

for that matter, you might submit your technical paper to PCA as well for publication in "Panarama" (?)

you are a PCA member, aren't you....?

Yes...I am working on that angle too!
