Help me soup up my boxster

[mikefocke]

You seem to be a results-based engineer and the results I've seen say I wouldn't let one near my car for longevity reasons.

Can you cite any independent tests that refute the ones cited here ?

I think that is what im going to do to get the power that I want, swap engines.
Ok, so should the 996 engine fit perfectly in my boxster or are there modifications I need to make?

This is one of the most disussed topics on the board so I would advise you to do a search on here and you will have more info than you can shake a stick at.

+1 Thank you Adam, I dislike repeating myself more than once.

Mike,
I typically am not a fan of K&N filters, in fact I generally find that they are counter productive for power plus a lot of the gripes that you stated in the article on your site.

The M96 filter has not followed suite with the previous units I have noted for other applications. I feel that part of this is due to the location of the Boxster's air intake. I have not noted any issues with the unit and my shop is at the end of a 1/8 mile dirt road.

I was able to pick up a solid 1 MPG (data logged) with the K&N in place and in every run on my dynojet I have seen a 2HP increase at minimum. Tonight I ran a test and saw almost 4HP from an engine that I was gathering baseline data from before we do an ECU flash tomorrow. I swapped the K&N for the stock filter back to back as I do with most every combination.

I give everything a chance to prove it's self and the K%N was something I was objective of until I saw the benefits in data, and didn't notice any degradation in filtration.

A bone stock engine won't see enough of a benefit from the K&N to justify it's expense and added maintenance, but when a 2.5 approaches and exceeds 200 RWHP the benefits are favorable.

My only gripe is that over-oiling the element can foul the mass air sensor and cause problems.

These guys here in Austin have a neat twin turbo upgrade for the boxster. I have driven one of thier test cars and i must say it is impressive. Enough power to scare the hell out of me. They sell it for @8-9000$. I suspect that your engine will explode after a while, but the power is monstrous.

Imagine a Jake Raby modified motor with a twin turbo addon....That would be insane.
I wonder if the car could even put that much power to use without melting the tires?

Jake,

I have used K&N filters since the 70's in off road racing. They worked great in that application but we cleaned them every race and rebuilt the motor every 10 races. I don't want to do that with my Porsche. I have studied the dyno runs, compared flow rates and particle intrusion testing and the K&N doesn't make sense to me on a M96 motor. A good clean paper filter still looks like the way to go. If we significantly increase displacement or intake flow rates, we may need a larger tuned intake and larger paper filter but a K&N still isn't clean enough.

I appreciate your knowledge and experience with Porsche motors and I have learned a lot from you about the internals of this very German machine. I have to agree with Mike on this. The K&N filter goes against everything you have been saying about improving the reliability of M96 motors over the past year. It is inconsistent with your design philosophy. Give this some thought while you ramp up production as a major player in the Porsche M96 aftermarket business.

No use in taking this original poster's thread any further off topic than it already has been.

We'll save this topic for later discussion as I continue to gather data and experience with the K&N unit. I will say that I have not outfit any customers engines with the K&N unit, only test vehicles and the jury is still out.
