Speak for yourself.

What's with this pillow over the face fetish all of a sudden? There you go again with the "...I will...". How much are you " willing" to put up for this commissioning? Either you are willing to finance a project like this or not, there is no middle ground. I think your bark is bigger than your bite....all talk and no action.

Good for you!



With regard to the intake, I don't care how ugly it is, if it works, it works.

James Bailey

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....

Mongo

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???

James Bailey

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.

Mongo

Funny Jim, I googled that intake and got mailbox pictures. People sure are creative.

James Bailey

Like they say it pays to think outside the mailbox.....

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...

James Bailey

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

GlenL

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...

Exactly ^^^ just look at the stock S3, with no factory knock sensors they were really detuned, however PKen fixed that for us

Imo000

Yup, he removed a lot of the safety factor that the factory put into the tune.

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.

And the really great part....I don't feel like I've missed a single thing!
