Sierra Sierra Enterprises Time Attack EVO 8. Tuners time to step up your game!
When a Formula Atlantic race team gets "bored" and decides to do a Time Attack, this is the result... Is it time for the "Tuners" to step up there game???
This is the result and blows away all the "Tuners" running
Big Willow in a blistering 1:20.54

Taking 2nd overall at the event was Jonathan Bomarito piloting the Sierra Sierra Enterprises Mitsubishi EVO 8 with a time of 1:20.454, which locked up fastest overall in the Unlimited AWD Division. This was Jonathan’s first victory of the season and the team looks strong heading into Round 3 at Chicago’s AutoBahn Country Club

I mentioned previously that I was working with the crew at Sierra Sierra Enterprises (SSE) and their Time Attack EVO 8. SSE may be new to the time attack scene, but they have been racing and winning for years in Star Mazda and Formula Atlantic. They have taken a hiatus from open wheel racing at the moment, but decided to build a time attack EVO 8 in house from the ground up. Dennis, the owner of SSE, is a real car enthusiast and has just about one, two, or three of every cool car you can think of. However, it was the EVO that blew his mind several years ago (he has 3 other EVOs) and this EVO 8 is the one SSE will attempt to be the fastest in. After some engine troubles with other engine suppliers, SSE has teamed up with Cosworth to supply the engines, engine calibration (me), and turbos. I should also mention that the engine used in the SSE EVO 8 is comprised of an off the shelf Cosworth short block and off the shelf Cosworth CNC ported big valve cylinder head. As a special program for SSE, Cosworth assembled a long block and the ancillaries. This service is not available to the general public.
Cosworth 2.2L 4G63 power will handle horsepower duties. Cosworth spec’d out just about everthing on the engine except for the dry sump oiling. A new dry sump oil system is being thought out at the moment. Wiggins clamps at almost every air and fluid connection = serious. A C&R radiator handles cooling and the Garrett IC core lowers the charge temps. The Garrett stacked plate core is really good, but quite heavy so Cosworth will be supplying a core that is significantly lighter in weight. Currently the engine has a Garrett GT35R turbo and makes anywhere from 450whp (@14.5psi) to 5xxwhp depending on boost, but Cosworth has supplied something a little bigger and badder that will use a Full Race twin scroll exhaust manifold. When time permits, a new exhaust system will be fabricated to accomodate the big power turbo.
The 6 pot Brembo Monoblocks are d-d-d-dope. SSE took some racing shocks from their Formula Atlantic spares, re-valved them, and with some fabrication made them fit on the EVO. The shocks are from Dynamic Suspension with Eibach ERS springs. Thats a Peterson dry sump tank in front. Currently the suspension geometry is stock, but there are plans to revamp when the time comes. Testing and development will dictate that time.
Here we have a Pectel SQ6 ECU, Pectel Center Differential Controller, and Pi Research Power Distribution Unit (no relays!). The SQ6 ECU is the basis of the Cosworth EC Pro ECU that I have been more or less working on non-stop. Admittedly the Pectel/Pi world takes a bit of getting used to, but once you understand the “system” you’ll find that it’s absolutely brilliant and super powerful. A Magden performance computer is currently used as a display dash. A Pi Sigma logging system and dash are going to be installed in the near future probably. The CDC and chassis track support is handled by Renu
Well equipped would be an effective description for SSE

I always wondered what a car would look like if it were built by a professional team.
Props to SS for entering a car in the series. Great team, great car, Bommer driving = one hell of a opening result.
Congrats guys.

Stuntman, congrats on your overall win this weekend. Any idea how fast you were going on the main straightaway at Big Willow this weekend? Everytime i saw your NSX blow past me on the straightaway where i was watching, just looked like a big green blur

That's doing work son. That car is awesome, the flat bottom reminds me of something.... oh yeah, my car.
Real race teams know about chassis setup and balancing the whole package, they also have good drivers. That's what tuners really lack. The CBRD car is similar, but built around modified class not unlimited.

^^^ I just put around in my car compared to the serious guys
Fun to watch for sure.
The adjustable sway bar and wing mounting are hot. Not to mention the front end being completely sealed off expect for ducting. I'd like to see the interior.

Alot of tuners are using professional drivers to pilot their cars...

I met Dennis Kottke at the Minnesota Mitsu Cookout last year.
He had interest in my E85 evo and wanted to ask me some questions. I answered a few and started to explain to him about the increased torque to the 6 speed being a potential issue and what one could do to try and address that....and then he very politely dropped that he runs a formula race team. ;-)
I had no idea I was talking to a Formula Race team owner getting into racing Evo's, talk about random encounter at a mitsu car show in Minnesota!?
Dennis told me about his car collection and always said the evo's impressed him.
Lets say the next couple hours I'll never forget, the information he shared, the knowledge of racing, the projects he was describing, I could have sat there all day and listened to what he had to share.
Dennis said he would send me some photos of the project and that's just what he did once he got back home. Great guy, a real gentleman.
Glad to see you guys competing and doing real well!
