Supercharger Installation!

[ohioboxster]

This is an update on my SC issues. It appears that I broke the oil filler tube at the block which caused a vacuum leak. I cant explain it either but the car is fixed and back on track pulling 16 in/lbs of vacuum at idle. It runs fantastic, heres a picture of the boost gauge after I picked up the car from the shop. I can always tell when there is a problem by this little gauge. If its not pulling the proper amount of vacuum or making proper boost you can pretty much know whats going on. Atleast get in the ballpark. The problem wasnt supercharger related, it was my fault for breaking the tube. Picture of boost gauge 10-27-2006

I just bought a 1999 and would liek to add a SC. Where did u get yours, how much should I expect to pay. Is the install difficult?

Thanks for the info.

Tghadley34,

You need to start on page one and read through the entire post. I went over the install, price etc. in pretty in depth detail.

These are comments from board members who have taken a ride in my car. I dont think they will mind that I kept all the Supercharger information in one spot. The car is running great. I just ordered four Porsche OEM 02 sensors and as soon as they get here Im going to take the universal 02's out.

From Der Geist,

Comments from the passenger seat:

OMG!!!!

Seriously, Matt was kind enough to take me for a jaunt down I-77 and show me his handy work. If I have to say it in one word it would be Frickin'-Awesome!!!!! When that supercharger kicks in it is one sweet feeling. Really nice acceleration. It has just the right amount of get up and go to make the car near perfect. I am reasonably sure that the car is pushing well in excess of 250 hp. I was thinking how the one thing that my Boxster lacked on the track was a little more OOOMPH coming out of the turns and that supercharger would sure cure that problem. I think that with an upgraded ecu and opening of the intake and exhaust system that Matt's car would be the ideal Boxster. And the sound of that supercharger is pretty sweet too. Guess I am going to have to start looking for a way to add some additional power to my car. Thanks a lot Matt-your gonna cost me some serious $$$$ keepin up with the Jone's hah-ha!

From Randall,

Well, I'm now sitting in the Columbus airport waiting for my flight home to hot and humid Houston. I met up with MikenOH, OhioBoxster and Der Geist today for lunch. Below is a lousy phone picture I took of us after lunch so you can see what they look like.

Also had a spirited ride in OhioBoxster's SC'd 2.5 ... He took it to 6k in every gear and when he upshifted, the force slammed me back in my seat! It felt as if he had put a completely different and much larger engine in the car, at just 5 psi boost.

Now I have what I need emotionally to save every penny and get an SC kit for my boxster. With this kind of power, one could theoretically, of course win most any road race with Mustangs, 350z's etc. LOTS more power in every gear.

ohioboxster,

if you were to do it all over again what would you have done differently?

I didn't see a intercooler on your list of items, do you think a intercooler would have helped with temperatures and would you recommend future S/C hopefuls to spend a few hundred extra on a intercooler as insurance against high temps?

Also what do you think about forged pistons? Would you recommend them? How many miles have you put on the car since the s/c and have you taken it to the track yet?

I think an intercooler will always be helpful but Im not sure if one is even manfactured for my SC kit. Im still thinking about alcohol injection to chemically cool the air charge. This kit only produces 4.5 to 5 psi dont forget. I wouldnt do anything different. My goal was a low budget supercharged Boxster and I think I accomplished that goal. This kit new is anywhere from 5-7k plus just think if you had to pay for install at 100 bucks an hour. Im trying to hit all your questions. I've probably put about 3,000 miles on the car since the install. Once I figured out the vacuum leak the car runs great, idles smooth, great gas mileage and tons of power. No track times as of yet, this is my daily driver some Im not real inclined to beat on it, although I want to. Sure forged pistons would be great but tryin not to break the bank. Before I would spend 20k on a motor and sc setup I would just buy a different car. Did I get all your questions?

[986_inquiry]

yep that's about all of them, but i don't think forged pistons would run 20k. I've seen shops offer to custom make any pistons for $700 if you're buying for a V6.

Im almost at 4k miles everything is great. Car is running fantastic, no check engine light and I moved my boost gauge to under the radio and CD/holder. Its in the middle so for now. In the future gauges can be added to both sides.


This is another plate I made to house an additional two gauges.

I never take my car but did not install the 24 mm front and rear 19.5 mm, purchased from the shops in Seattle, Sunset, and the car corner flatter than before and have been a comfort compromise. I am sure that still active in control of their car is more accurate to ride.

can someone please get this idiot off the board!!!

[RandallNeighbour]

I'm with you. Gibberish!

IMHO people that create / propogate spambots should be sent to Libya to serve in Ghadafi's army.
