Installed EVO Intake, Holy Crap!

[zackwatt]

I installed the EVO intake last night. Wow, was that an ordeal! It was the hardest easy job I've ever done! I think the install time rounded out to about 5 hours. Taking everything out was a nightmare. The stock Airbox was a PITA. I ended up having to cut it out. But when it came to putting everything back together, the job went rather smoothly and have no problems once everything was back in place. The sound is nice and alot smother through the revs. All and all it was worth it. But seriously, an intake should not require this:

Yeah I heard you have to tear up the stock box in order to get the evo or any similar intakes in. Kinda crazy. I don't think I would do that to my car. Does that rubber seal actually seat up against the lid? I don't see how it create a tight seal since it's underneath the mounting points.

It seals well enough. It is a heat shield not a heat box. The main point of it is to prevent huge waves of from heat soaking the intake. It does not have to be 100% enclosed. Besides you're pulling in more then enough "cold" outside air to compensate for the little amount of hot air that might seep in. BTW, the stock airbox is really restricting.

Is the increased HP noticeable?

[Wingnut2u]

Personally I think the sound is nice but the performance increase is not really noticeable. For the money I wouldn't say that it was a worthwhile upgrade, but that is just my opinion.

[Jaxonalden]

By the looks of the snorkel, the route the air takes in the intake box and the restrictions of the intake pipe that the EVO setup would allow air to flow more freely. HP gains? I'm sure their nominal. If we had some sort of forced induction I'm sure the upgrade would make a huge difference. But being normally aspirated you would think the numbers do grow in the higher RPM range, but not by much.

Wingnut2u, if you don't want your new intake setup I'm willing to run back down to Dallas and make you an offer just like the other stuff I bought.

P.S. As you can see the painted bumperetts aren't on in this pic.

That is a lot of wrk for benefits that aren't that significant... 5 hours work should net 25 HP :-)

Nothing in these cars is cheap or very effective. I can get an STI an extra 100-150hp with bolt ons and $5000. $15000 in a Boxster gets you 43hp. Great little cars, but not cheap or easy. :dance:

$15k and only 43hp. Where are you shopping? I just had a Gemballa Bi-Turbo setup installed & tuned in my '02 986S. Total cost of parts & install labor was just over $14k and it netted me 508hp

Be careful that the filter that came with the intake does not have too much oil on it. I blew out my MAS real fast with that intake. Just my 2 cents. Hopefully they redesigned a bit.

Saved the pics. Seen the airbox mounting tabs broken off to get it out, but that looks like a fight.

Once asked a mechanic and he said he lowers the engine a bit and then can get the box out in one piece.

[seningen]

If you are pulling the engine (i.e. extraction
of the old one is not an issue)
- what's the best air intake bang for the buck.

Might bore out a 32.L to a 3.6L and put Nickies to fix
a blown '00 S.

considering other changes while I'm at it.

thanks,

X51 upper intake Seriously, all the different systems out there do NOTHING but move the hp + torque numbers around in the RPM range. Do we think 1-3 engineers working at a plastics plant can "out engineer" Porsche? Those of us who have worked in the pro ranks call it "imagineering".

Sorry for being so harsh. I just found out someone installed a "hot air kit" on my brothers Boxster before he bought it. Why would you do a K+N snorkel in the engine compartment of a Boxster?? when STOCK it pulls fresh air from outside?? WTF??

What will this intake do to the numbers? Cost?

[Brad Roberts]

Porsche sells it as part of a "kit" which is the way tuner's *should* sell stuff for our cars. The X51 "kit" is available from the dealer, but this intake is not designed for the Boxster engine compartment. The difference between a 996/997 intake compared to the Boxster is the "height" of the intake. The 996/997 use longer effective runners. Not a big deal, but requires lowering the front engine mount 1.0-1.25 down so the intake clears and no mods have to be done to the engine cover.

Right now, we have someone dyno testing different solutions for the Boxster engines using the different heads on different blocks and different intakes on different heads with different exhaust cams. We are playing around with 3.4 engines by installing 2.5 cranks to build short stroke high RPM engines... Very soon you will have a LOT of options. Right now, very few people actually have a clue about these engines (evidence is the number of turbo and supercharger kits out there) Basically "bolt on" solutions. We learned a long time ago that X51 exhaust cams REALLY wake up the 996 engines. Now custom cam grinds are being done and tested. Watch Excellence magazine for an update within the next 6 months.

Could you give me the bore diameter of that throttle body and it's Porsche p/n?

Thanks in advance,

Throttle Body part number is:

997.605.116.00

Porsche current list price: 292.22

It is now on the car (CaymanS) so I'd have to dig back through some notes. I did measure it, just don't recall what the number is!!

My '04 S gives me a good kick in the pants. Would this intake be worth putting on? I understand about the clearance problem and I'm sure the strong dollar will make this a very economical upgrade . That being said I'd like to know if I would also have to have head work done to make this intake produce its true performance numbers or if bolting it on will work just fine.

I'm sure the boys in Stuttgart did their homework and what I have now is the best reliable solution at the time. My cars running great now, quick enough to kill me, but I would like to die a little quicker.

[blinkwatt]

Every other person that i've talked to that owns a supercharger kit has blown an engine and they end up moving to 3.4Ls.

Just thought I'd throw that out there.
