can I put a pillow over your face? seriously, you are that barking little dog in the hand bag!
Yes, I will put up the cash.. greg and I have to hug it out first. I don't think he wants to build one for me... could be wrong... but I have NO problem with greg. he takes the bantering too seriously here. we see eye to eye on much more than just clutch adjustment and oiling issues!

Where do you come up with this stuff ?? There are so many ways to screw it up that it boggles the mind. Batch injected engine makes balanced air flow rather critical or the knock sensors will be dumbing it down to the leanest cylinder. Seriously " cant get any worse " trust me even that Salsbury 4850D Plenum design might actually be worse at least at low and midrange probably excels at high speed runs or country road rallies venues.... which by the way is what it was designed for....

I was looking at some of Greg's manifold pix. His plenum box reminds me of a sheet metal style, with some trickery inside of it to get the gains we saw in his dyno sheets. I'm sure there is some sort of velocity stack incorporated into it. The throttle body needs to be bigger with any of these custom manifolds though and NOT the S4 one. Say 90mm+ maybe???

When at the Silverstate Classic Challenge in Ely Nevada last year there were some very "creative" vehicles entered as just about anything goes....did observe what appeared to be Salsbury 4850d or at least very similar replicas while I was there . But again this was an open country road high speed event so no real surprise. I actually lost count on the number. But with a $100 price point no wonder.

From some of the comments in this thread, I have to assume that Porsche actually tried to put out 50-100 hp less than they could have. Which strikes me as kinda dumb, but what do I know...

Conspiracy theory is they did not want to upstage the 911 Turbo.. or want Kibort to actually WIN races.

All passenger cars put out less than they might. That's how you make an engine go 200K miles instead of 1000. And they needed to make emissions regulations. This is why it's easy to boost power on street cars: yank the cats and remap for (dirty) power and viola! Turbos are great for that. Crank up the boost until it blows! The list goes on...

It's really funny reading this thread when two of them are blocked. I can't imagine the pain some of you are going through.
