The Lotus Exige S is known for heat soaking and extremely high IATs (intake air temps). The stock intercooler is mounted on top of the hot engine and doesn’t get nearly enough airflow through the small roof scoop. It also doesn’t help that the hot air from the radiator exits in front of the windshield and makes its way into the roof. There are some things you can do to help like a larger intercooler, additional ducting from the side scoops, larger roof scoops, and adding fans cooling to the intercooler. These are all help a little, but the stock ECU will start to pull timing as low as 104F, and pull as much as 6 degrees as the temps rise. The last time we were at Buttonwillow in December, we logged peak temp of 167F while out on the track. Remember, this was in December when it was nice and cool.
This past Monday, June 24, we decided to take a team day-off to go to the track with Golden Gate Lotus Club. In addition to drives, meets, and fun outings, GGLC hosts great track & autocross events. Only three run groups, so you get SEVEN sessions! Not to mention, they always offer snacks, coffee, fruits, and sometimes even lunch!
It’s no secret that Reverie makes high quality (wind tunnel tested) aero parts for the Eliges and I’ve always liked their front splitter design. Although Reverie’s mounting solution works great and is solid, I decided to attach the splitter directly to the chassis, and not to the front clam. My reason for this is so that I can easily remove the front clam without having to remove the splitter first. This did require cutting the front lower portion of it so that it could just rest on top of the splitter…
When we first acquired the Exige, Victoria and I had multiple conversations about what we wanted to do with it. Our original plan was to keep it street-legal, and just use it for canyon driving and the occasional HPDE events. I knew that it would have a much higher resale value if it was kept street-legal. Plus, being that this is our first Lotus, we liked the idea of being able to take it out every now and then. We also wanted to take it on long road trips and enjoy some of the fun back roads we have here in California. …Well, that idea didn’t last too long.
My first encounter with Lotus cars was when I was 18 years old and I signed up first my autocross in my 1996 Acura Integra with the Golden Gate Lotus Club (GGLC). I always thought they were “cool” looking and after going on a couple ride-alongs, I could already tell how fun it would be to drive one. ...
This past Saturday, the Exige returned to Sonoma Raceway for the SpeedSF Challenge time attack event in the "S2" class. The competition in this class includes cars such as the Porsche Cayman GT4, Chevy Corvette (C5 Z06 and C6 Z51), and highly modified Hondas and Subarus. This was the first outing with several changes to the Exige performed by Trackspec intended to help it be more competitive without compromising the ability to drive it on the street with a full interior and air conditioning.
This past Saturday, April 7, we hosted our very first Trackspec Tech Talk, "Handling 101," featuring Shinoo Mapleton, owner of InoKinetic. Being in the Lotus industry for several years, Shinoo offered his knowledge on car handling, for Lotus Elise, Exige and Alfa 4C.
