911 S Throttle Body Installed - 986 Forum - The Community for Porsche Boxster & Cayman Owners

blair206 · 10-17-2012, 06:49 AM

Hey Guys

I keep an eye on this and Pedro's board and have been reading the posts here regarding larger throttle body installs.

I've installed one on my 2004S SE. Bought off Pedro.

I Dyno'ed the car before and off to have it re-dyno'ed later this week.

If you guys have any questions I can answer, fire away.

Great! Can you snap a picture that includes the airbox? I assume that the is a 987 box in there

Needs a leaf blower in there as well.

Needs a jet wash in there more like !!! Dirt was everywhere !!! I'd just got back from a contract in Arkansas, the job site was a 1/2 mile down a dirt road.

Yes it's the 987 air box.

I'll make a note to grab a pic of the air box.

Pedro's instructions were for the standard air box. It did take a lot of head scratching and a trip to Home Depot to make it work, because of the difference.

Best pic on hand. Shows gap I was stuck with.

so what is the setup you got from Pedro?
did you get TB only, or the technotorque plenum as well?

blair206 · 10-17-2012, 08:47 AM

I got the TB the plenum and the chip flash. Basically the whole thing.

Sounds great! I have a BMC air filter and fabspeed cat-back pipes too. Also have Pedro's engine mount in. They were all on the car prior to throttle body and made a little sound difference. Car sound when you put your foot down is deeper and louder, less jap bike. No drone at all though.

I had 270hp with those mods so I'm expecting something in the 290hp range when I go to the dyno Thurs/Fri. Butt dyno says 20-30hp. Fingers crossed. I also put the BBI under-drive pulley on at the same time as the TB.

Car has 55,000 miles.

So base 264hp (no Dyno verification)

Dyno with Cat-back exhaust, BMC, Pedro's engine mount and Technotorque2 270hp

TB etc and under-drive pulley ????

So my first Dyno didn't tell me much as I never thought of doing a base line run. Hp base, could have been lower or lack of chipping the car wasn't taking advantage of the initial mods.

Now however it should show what increase the TB & UD pulley with chipping makes.

blair206 · 10-17-2012, 08:49 AM

oh...I also have driven 2400 miles since installation. No CEL's etc.

blair206 · 10-17-2012, 08:55 AM

On Pedro's advice I also removed the "air Pump" for Cal emissions and the "chip" Pedro did was for RoW spec car.

Pedro was great help through out the install process. With my different 987 air box I nearly threw in the towel and sent it back! lol

But after many hours and phone calls with Pedro we got there.

Meir · 10-17-2012, 09:28 AM

this is unbelievable.
its like you almost fell out of the sky for me.

i have a Cayman S TB and plenum seating in my garage for couple of weeks now.
did not installed it because i'm thinking about getting the technopower 2 kit (for a while now)
problem is, i need to complete my custom exhaust mod, and install some headers, before going with the ECU remap. (plan is going catless.)
just this morning, i was thinking about giving Pedro a call, and drop by to pick up a technotorque plenum, that will fit the TB i have.
plan is, to install the technotorque plenum and the TB now, and flush the ECU later on, after installing the headers and modified exhaust.
headers will go on in couple of months, after completing my "winter project".
clutch,IMS,RMS,AOS,UDP and coolant tank.
its still too hot in my garage, so ill have to wait for the temperature to drop a little.

ill wait on your dyno results, and probably pay Pedro a visit next week.
thanks, and keep us posted.

blair206 · 10-17-2012, 09:59 AM

I will let you know how the Dyno goes. I'll post the results. The guy has all my dyno runs on his comp.
If you need any info on how the install went be glad to chat with you.

I just called the Dyno guy (only one in Atlanta!) and got his answering machine, hope he's not away!

I'm real happy with it, well worth the hours of sweat!

blair206 · 10-17-2012, 10:11 AM

Is that AOS going to be the standard one or the racing one ?

I have one in the garage I've never got around to fitting. Be nice to see how much trouble that thing is to change out.

sometimes it is more impotent that the "butt dyno" is happy

No. i'm going with the "regular one".
should be much more easy to do when the trans is out of the way (same with the coolant tank), that's why i'm thinking of doing it all in the same time.
the UDP ,headers and exhoust, will go on only after the first part of the project will be completed.
the UDP, because i would like to have the engine at perfect TDC using the OEM pulley.
headers and exhaust, just to make sure every thing works fine and quiet, after the IMSB is installed.

Meir · 10-17-2012, 10:39 AM

just came to my mined, that i'm going to be in Atlanta next week.
wan to meet for a beer?

Great I want to know how the air box fits in the 986 engine bay specifically
at the left rear corner where there is a muffler chamber adjacent to the 90 degree bend in the airbox outlet ....it is a mystery to us

Apparently the wall tightens up in the 986. Just looking at your engine bay opening I am noticing sheet metal hem differences. The more engine bay pictures the better.....after the shampoo!

If you are able to spot part numbers of the airbox and MAF housing that would be great too
