$839.00 - FRP
$1,090.00 - CF
GT3 style conversion bumper for 996's thru 2001 and Boxster's thru 2005. Direct bolt on.

Spoiler lip is a factory Porsche Motorsports part. I think you can get them through Getty Design too. The Porsche part # is 996.505.986.91 and the factory fasteners are 999.507.497.40 x 15 of them. I've chosen to use a bit different fastening but the factory ones work too. I think the lip is around $175.

If you need help sourcing them, let me know...

Yep, same car. I stuffed it at the outside road course in Las Vegas back at the end of 2010. It was repaired with all factory parts at the tune of about $15k... It's all closer to factory spec than new now. Was expensive to repair, but glad I did instead of start all over. I raced it in BSR for all of 2011 and then took it apart at the beginning of 2012 for this new revamp.

Thanks! Hope the thread can be inspirational for a few out there looking to go the same path. ( the race car path, not the crash one )

It does make me want to have a track car even more. But, it also makes me want some actual driving skills too. Sheesh, before I start talking track cars, I really need to get into some DEs and AXs.

I'll get there one day. It won't be as nice as your car pictured here though!

Hey, come down to San Diego for the Performance driving school in October.
2.5 days of training with a full day of learning/driving Auto cross on the last day.

I'm prepping for it now, Tires, Brake Flush, oil change etc.

It will be my intro to Auto-X and eventually DE track days, plus I'll learn how to drive it in a non-competitive atmosphere which is always good for first timers.

Seeing the full fledged race car pics sure gets your imagination working to see what might be possible for yourself.

I knew a guy who raced for Porshe Germany in the 70's, always loved hearing about his experiences and later his videos of Stock car racing in Canada.

Very exciting stuff!!!

Nice work Eric. I believe #23 is clearly the fastest Boxster in the west.

That car is such a sexy beast. I would love to just take it around a track. Cheers to a well done, phenomenal car.

Eric,

Way to kick some cup car butt! Fantastic! Getting past/along side on corner exits....the corkscrew is just incredible!

Did I see some left foot braking in there? For corner balance just before and after the power comes on in certain corners? Does it help you get some more oversteer?

Will "they" let you vent the rear window?

Thanks! I'm sure they don't enjoy getting passed by a hairdressers car with a street M96 motor in it

Yes, I left foot brake every corner that I don't downshift. Actually, even on downshifting corners, I will move my left foot over to the brake pedal to take over braking after downshifting is done. It took me about a year of street driving and practice to really get the feel and coordination down to get it right, but it was well worth it. Now I can modulate equal or better to with my left foot over my right foot.

I do use a left foot tap to get the car to oversteer and control balance as well. If the car is pushing in a corner sometimes a lift off the gas will do it, but a tap of the brake that coincidences with this lift gives an even greater effect. Getting weight transfer off of the rear tires and on to the front can get some more grip up front and allow for a little slide in the rear.

Also, towards the middle of my in car camera at Laguna Seca I was having to pump the brakes with my left foot before entering each braking zone. I was suffering from brake pad "knock-back" with the high G corners and corkscrew. The flex in the caliper and rotor would knock the pads back away from the rotor so the first application of brake would be soft as they returned to the mating surface. Similar to the feel of overheating fluid but a different mechanical issue.

The hard top and rear window were originally built for my Boxster Spec car. At the time, we were not allowed to "vent" the rear window at all. I was also not doing 160+mph anywhere. So that was a big concern after watching the rear view camera at AAA Speedway for the first time. I will have a new roof and window set-up for next year for certain. The wing will also be reinforced.

Eric523,

WoW! Now THAT is a serious car! Thanks for even letting me view it here!

Got any driver openings?

Just a thought….but why not go with a dual exhaust straight out the back? It occurs to me, and I'm not a mechanic or a racer car driver. In your exhaust setup at the rear with the bends going back to center, you could shave another 3 lbs. in exhaust tube weight alone. I'm sure you need to 'marry' the pipes to balance it out but could you do that with an "X-tube" type setup closer to the headers or a "bleed" tube of lessor weight and diameter?

Also, would like to see your intake system…IF you happen to have one of those pics.

Were you the only Box represented in the field? Didn't see any other 'side' intakes.

Keep up the good work…and keep us posted! :dance:

Thanks! On the exhaust stuff, yes we do like to merge the two sides together. With the suspension subframe and longer 6 speed transmission case, there isn't much room to do any merging further forward in the car. We can't run any pipes underneath because of the low ground clearance either. The pipes I have now are a little longer than absolutely necessary, but that is because we wanted to be able to insert the largest mufflers possible in that straight section in the back leading up to the merge. Every once in awhile we run tracks that have a maximum decibel reading, and the option of adding mufflers there was a goal.

I think there is a few pictures of the intake set-up earlier in the thread. Basically some 3" aluminum pipe running from the throttle body into the rear trunk by the coolant tank. The right side air scoop on the side of the car has been modified to feed air through the right rear quarter panel and into the trunk. A larger cone filter, some sensors, hoses and hose clamps...nothing particularly fancy.

I was the only Boxster that far up front. There was one other 3.4L conversion Boxster there that weekend but it was a few seconds back. There is a Cayman in my class that has some side intakes too but we ran pretty good gap on that car as well.

Thanks. I consider it my dream Boxster as well! Drove a 2009 GT3 Cup Car last weekend at Willow Springs and I can honestly say I wouldn't trade my car for it.

Fantastic driving. I noticed in the corkscrew you were spinning up the tires. IS that because the drop is so steep that you get so unweighted that you lose grip? Laguna Seca, car or moto, is definitely on my bucket list.

Thank you. The corkscrew is my favorite corner I have encountered on any track. I do get quite a bit of wheel spin going over the crest due to the lightening of the car. I could probably get out of the gas a bit to reduce this and save tires but it's so darn fun! I quickly regain traction at the bottom under the heavy compression. I tend to shoot out of this corner better than any of my competitors and I have made the race winning pass going into the next set of corners in 5 out of my 6 races at Laguna Seca. They aren't studying my videos well enough... Maybe they will figure it out next year.

Some changes are in the works for 2013! I'll be coming out with some new items that should improve the lap times by a bit and change the look of the car. I'll share when they are completed

In the meantime, just bought myself another '98 Boxster to drive around on the street! Looking forward to being able to drive one more often now that the race car is so expensive to run.

Can't wait to see them....maybe you could do a flat underside and diffuser for the rear of the car....would likely save some drag at least

Your flame shot picture is a keeper!

getting a late start to the season this year mostly due to a heavy workload in the shop. The car will make the 2013 debut April 5-7 at the combined PCA/POC/Pirelli cup Festival of speed event. I've kept most of the progress under wraps from my competition to this point, but once the car gets some fresh paint next week I'll share some more news! If any of you are going to make the event, please stop on by and say hello.

Cage upgrades were on the list. Some of the recent accidents had me thinking more about the speeds this car is reaching now and it doesnt always have to be a mistake to get you in trouble. Added some more 4130 to the cage and also quite a bit of reinforcement to the seat brackets.









Upgraded the ABS system to a four channel TEVES stand alone unit. This is the street car M3 version which is a fraction of the Motorsport unit price. Same pump but the programming is not customizable.



Upgraded to some new 997 cup suspension parts front and rear. Installed some later model subframes that were quite a bit beefier than the '98 versions I was using before. While we were at it, the pick up points were raised a bit.





last but not least, adding some air conditioning!

Could you share some more details on the ABS unit you installed - why did you change from the factory Boxster one?
