The Ultimate 987 Porsche Cayman? Home-built autocross special-500+ hp with wild 4.0-liter engine

-----------------------------------------
Steve Lau and Tara Shapowal-Lau are no strangers to autocross, competing for Fast Time of Day in both SCCA and PCA events. In fact, they're both SCCA National Champions in addition to being Porsche Parade champions! This year, they brought what is one of the most focused and impressive autocross race cars we've seen: a home-built 2010 Cayman S named Stormy equipped with a special, 500+ horsepower engine. If Steve shows up to a Porsche Parade autocross, he usually walks away with FTD. This year was no different, though his closest competition, his wife Tara, nearly took top honors. As it stands, Steve's 45.840 and Tara's 46.534 were enough to secure first and second places overall. Watch this video for a full breakdown of their autocross build, including what powers the quick croc. Stay until the end to watch Steve's FTD run and Tara's second-best run (unfortunately the GoPro overheated for her third and best run).

Yeah no one is beating these two. That car is awesome. Nice that the Porsche engineers at least planned for the good stuff to bolt to this chassis, even though they were overruled by the marketing crew until recently.

[@DC5Brandon]

I just started the video and as a 987 autocrosser and member of the AL chapter of SCCA myself, I can already tell these two are my new heroes!

[@PorscheClubofAmerica]

Indeed they are for many!

[@kaplanmb]

Is there any where we can find more details on the build?

[@Nusantara.Partners]

Way to throw down for the high HP Caymans!!! Stormy, Stormy!!!

[@PorscheClubofAmerica]

It's an amazing build!

[@sharkfin9517]

Well done on the autocross focused Cayman setup! great content to share, thanks Vu

[@PorscheClubofAmerica]

Thanks for watching! This car was fun to watch on the course and to explore with Steve and Tara.

[@bernardwarr4187]

Definitely looks fast across that parking lot

[@kkendler8570]

Thanks for showing us the details of this Cayman.

[@PorscheClubofAmerica]

You bet!

[@javiervaron]

GT3 engine?! WOW!

[@PorscheClubofAmerica]

Exactly!

A hybrid street version of this is my dream car. Thanks for sharing. 👍🏼

[@PorscheClubofAmerica]

Our pleasure!

[@STANGKILLASS]

love the build and build breakdown portion!

[@PorscheClubofAmerica]

us too!

I installed the TPC Turbo kit on it before they bought it. We drove it 2-3x but couldn’t get the COBB tune correct (even working with COBB) I couldn’t tell from the video (I’ll watch it again) but this car was chosen to be built into an AutoX car because of its PCCB option. We wanted the car as light as possible. Since then? I’ve gotten another Cayman down to 2400lbs but it took a LOT. Think acid dipping the tub etc. Carbon roof etc. Next up is a 981 with double A arm 992 front suspension.. and double A arm rear. Struts suck.

[@PorscheClubofAmerica]

I believe they took the PCCB's off.

[@Nusantara.Partners]

Have the TPC turbo on my Cayman that we AX for a decade in GGR with Steve. It was a pain, but was able to perfect the tune on ours (lucky)....

The perfect car for the hill clime in
Switzerland

[@PorscheClubofAmerica]

That would be amazing!

[@ttfrhoncho6716]

Nice. As someone probably starting an STU build next year, in a 981 base, this is cool. Getting tantalizingly close to local competition on non-autocross tires, and only Apex 9.5 and 11" wheels keeping me out of B-Street.

[@user-po7tn5jq6w]

Thanks for this great Autocross coverage! Even better than your Concours video...IMHO.

Glad you liked it!

[@PorscheClubofAmerica]

We see what you did there...love it!

[@MarkCup70]

I planned on keeping my Cayman totally standard, forever. Now I'm not so sure. Nice ride 👍

[@PorscheClubofAmerica]

Tempting isn't it?

[@AJTalks]

Gorgeous build. Dream spec with the Ohlins. What's the story with the ECU and wiring loom?

[@PorscheClubofAmerica]

It is indeed!

[@Dave-White]

Great interview - very well done.

[@PorscheClubofAmerica]

Glad you enjoyed it!

[@Adamoda14]

Great video and useful.

[@PorscheClubofAmerica]

Thanks for watching!

[@scottoconnor3484]

How do you generate meaningful downforce from the aero components at Autocross speeds, when the corners are typically taken at 30-50 mph?

[@racertea]

At those low speeds, it doesn’t really make a big difference. We do race at places with higher speeds and can feel it working. Ideally though, we’d have a much larger surface area, but are restricted by club rules.

[@Mark_Meisho_Thompson]

Should have got the offsets for those wheels!

[@Pccart1121]

Late to this video. When he says “stock transmission”, is it the stock Cayman transmission or the unit from the 991.2 GT3?

[@AaronEsau]

I am also curious
