Mantis Sport Cayman takes on the establishment in World Challenge

Mantis_Sport_WC_01_340pxErnie Jakubowski of Mantis Racing operating out of Oakville, Canada (just south of Toronto) has been racing Porsches longer and harder than just about anyone. During his passionate racing career he has achieved countless Porsche race wins, podiums and championships but now he's gunning for glory in the World Challenge GTS series in his yellow 987.1 Cayman S.

The Speed World Challenge GTS class has been dominated by the Cunningham Acuras since the GTS class began. The team has achieved numerous victories, poles, records and consistent drivers and manufacturers titles every season making them one of the most dominant forces in motorsports. The Cunningham racing dynasty is a full fledge factory effort with factory resources from Honda/Acura dedicated to finishing on top of the podium and capturing championships.

This dominance has been tested over the years but never really threatened. That is until this past 2010 GTS season when a new sheriff rolled into town driving a yellow Porsche Cayman S. Below is the "David vs. Goliath" story of Ernie and the Mantis team's impressive "partial" season effort against the Cunningham Acuras and the more potent Mustang GT's, Corvettes, Vipers and Porsche GT3's told by Ernie himself.

Mantis_Sport_WC_02_400pxWell to start, MantisSport wasn't even contemplating racing World Challenge in 2010. The plan was race several PCA races; Sebring, Mid-Ohio, Watkins Glen and Mosport. World challenge phones up and asks if MantisSport would like to race in their new GTS class. Sure why not, "like giving a drowning man a anchor". Its midway through the season, Mosport (May 24th) weekend race is between the Mid-Ohio and Watkins Glen PCA races, 3 races in 3 weeks not happening. We had not even tested with the spec Toyo R888 tires. MantisSport makes the races at Sebring and Mid-Ohio but missed the WC race at Mosport. We did however "observe" the race at Mosport. Next weekend raced at Watkins Glen PCA. That week we finally tested on Toyo tires. Mat White 3 time FF champion comes to test with us. With 2 data samples, we conclude we could be competitive in World challenge.

First WC race is at Watkins Glen a few days later. We feel good about our chances and order up another set of tires for the race. They are 2007 tires that don't feel great, second practice we change tires back to the 2010 test tires still beat up from testing but managed to improve 1.5 seconds. Needless to say, we qualify and race on the test tires. After the dust settled we qualified 3rd and finished 3rd.

Second WC race, home town track at Toronto Honda Indy, I have raced here twice before so I feel we have a slight edge. Again, we qualify 3rd but know we need more performance to beat the Acuras. The search for more HP and improved handling becomes critical. Under braking, the car isn't as stable as when shoed with Hoosiers. The light goes green and we get a perfect launch putting us in P2 going into turn 1. While battling for the lead we get hit and spun by the Acura. We fought back, regaining second when the checked flag finally dropped.

Mantis_Sport_WC_03_smThird race Mid-Ohio, we get a 100 pound break on weight putting us at 2900 lbs instead of 3000 lbs with driver. Unfortunately we receive this news at the track. The Ford Mustangs show up with FR500s, plus some additional Acura's, we have our work cut out. Again we qualify 3rd out pacing the mustangs V8 power. Saturday's race ran up in second until I spun into a gravel trap. Sunday's race started with a perfect launch giving us the lead going into the first turn. Cunningham gets by 13 laps later after working on me the whole time, he slowly pulls away. The field gets packed with a full course caution 6 laps from the finish. When the track goes green the GT3 behind me (who initially caused the caution), passes me coming onto the straight. Unfortunately the GT3 then cut in front of me, clipped my front wheel and sent me spinning off. After regaining control I find myself 13 positions behind. During the next 2-3 laps I drive the Cayman at the absolute limit working my way through the field passing cars every opportunity until we regain 3rd place when the race ends. Now that was fun and I wasn't going let that race be a poor result.

4th WC race, VIR, we properly put the Cayman on a diet and found some additional performance. Weight loss came in the form of lightweight doors which shed 40lbs, while additional performance came from a GT LSD unit which provided much improved stability under braking. Additional power came from upgrading the standard 74mm IPD plenum with IPD's "competition" 82mm Plenum and GT3 throttle body.

Mantis_Sport_WC_04_smThe weekend of Mistakes. We again qualify 3rd, but left the hot pits without asking. Well that got us a penalty forcing us to start from the back of the class, no time. Saturday race start saw us go from last to 6th before turn one, I am beside Cunningham going into turn one, he started pole. A Corvette and Viper end up spinning in front us, I let Cunningham go, Corvette almost hits Cunningham. Cunningham pulls away when it starts raining. The second Acura has been on my heels but falls off the pace (rain?) and I start gaining on the leading Acura. A few laps from the end Cunningham pulls into the pits (engine issue) We win, then do not. We are found to be ½" too low ahead of the rear wheels during post race inspection, the engine sump is sticking down ½" too low, DQ'ed. We spend 3 hours getting the car to the approved ride height, raise the rear, the front chin splitter is too low, the rear wing is too high, got it right.

Saturday night, both Acura's have their engine changed, maybe we are finally pushing them? Qualify again 3rd, now the crew is also taking care of two 944s in the National championship race in the morning, we loose track of time. Late for pre-grid for the WC race, there's a penalty for that, starting from the pits, not happy about that. At the start there's a big accident, missed that. 30 second behind the Acura's after lap 1. Managed to bring the gap down to 7 seconds at the end after driving through the Touring and GTS field to finish 3rd.

5th race of the WC season and last, Miller Motor Sport Park. After a very long drive out, 1 day early to acclimatize. The goal this weekend was to survive, gather enough points to finish 3rd in the GTS points, which we did. Now since we will be switching to Pirelli slicks next year, we didn't buy new tires for this one race. Thought we would have things well in hand. Surprise, WC gives the Mustangs 80hp more, 300 lbs less weight and 2 corvettes show up. This is a horse power track, damn, but we still qualify 7th on old tires (pretty quick), If we had new tires we would have been right up there. The race, standing start, I get a smoking start, I think I could have cut it even better as it happens, within 100ft I am in second place only the Corvette which was on pole ahead. All short lived, as Cunningham and I contact each other as we pass the start finish line, I end up with a cut rear tire. One long slow lap into the pits, change tire and finished high enough to get 3rd in points.

So in the end, MantisSport finished 3rd in GTS points and won the Game Streamer Rookie Award.

Thank You to IPD for their 82mm Competition Plenum that utilizes the 82mm GT3 throttle body. It just plain worked and delivered the additional power we needed to challenge those dominating Acuras.

A Cayman with Teeth that Bite - The RS 350

Shark-Werks-RS350-Cayman-S_thumbThe canyon carving mid engine platform of the Cayman fills a void in the Porsche line up once dedicated to the "Hill Climbing" audience. Famed Porsches like the 550 Spyder, 718 RSK, RS 60, RS 61, RS 62 and the 904 were designed to deliver incredible performance in small lightweight packages. The Cayman delivers a driving experience on par with these legendary and celebrated sports cars.

Unfortunately the Caymans were "de-tuned" and delivered under powered so as not to threaten, or possibly even dethrone, the Carrera's patriarchal position in the Porsche family hierarchy. Although the Carrera's performance can be much improved upon with typically performance upgrades, the Cayman absolutely comes alive with an equivalent upgrade package.

The ultimate street performance expression of the Cayman S comes in the form of the Cayman RS350. This perfectly sorted and balanced performance package was the result of a collaborative effort between Shark Werks, Evolution Motorsports, RSS and IPD. The RS 350 Cayman package is the most tested, developed and proven performance package available anywhere for the Porsche Cayman.

The authoritive Porsche publication of North America, Excellence magazine, was quoted as saying, "The RS350 is one of the best modern Porsches we've driven on the loop, and the best 987.... Maybe that's why it always keeps pace with the far more powerful 997s and 997 Turbo."

The RS350 was definitely the "under dog" of the group, both in terms of mods installed as well as overall out-of-the-box power. Drivers of all 3 cars unanimously agreed that, had the Cayman been equipped with an LSD and/or Moton dampers (like the other cars tested) "the Cayman might move from merely one of the best-handling Porsches we've tested on the loop to top dog......an amazing feat considering the money involved."

IPD always enjoys working together with top Porsche tuners and helping develop new performance packages. This process is never more rewarding than when working together with the talented guys at Shark Werks and Evolution Motorsports. The success of the RS350 Cayman project was the direct result of dedicated team work combined with uncompromised development, relentless tuning and a passion for Porsches and making them perform even better.

There are many different performance packages available for the Cayman but the best ones on the market have one thing in common, they all utilize the IPD Plenum. The IPD Plenum out performs every other intake system on the market. Don't be fooled by other competitors claiming to offer Plenums. All factory Porsche air distributors are of the "T" variety and therefore suffer from less than ideal air flow, intake air speed and total performance. The Shark Werks RS350 packages comes with the Competition IPD Plenum that is specifically design to accept the larger Porsche 82mm throttle body from the 997 GT3 RS.

IPD would once again like to thank Shark Werks for their commitment and over-the-top effort in making the ultimate Street Cayman S capable of terrorizing any track, the RS350 Cayman.
