Ecoboost Birkin

[Tbox56]

Took the Ecoboost Birkin XS for a first drive today. The engine and ECU package is from Ford Racing 252 hp and 360 lb/ft of torque. The first drive around the industrial park was on the verge of scary. The power comes on so strong you can freely spin the rear tires in 3rd gear from between 25mph and 50mph (and probably higher but I want to keep my drivers licence). The delivery is very linear and just pulls harder the higher the rpms go. Still some work to do to finish the car and I need to adjust the tube from the intercooler to the intake, fortunately this is the only fabricated item that did not fit exactly as planed. Will post a link to a crude video after it finishes uploading.

UhOh, looks like there is a new top gun in town. Nice work Tom, Seb and Simon are starting to tear down their engines and are trying to figure out how to stuff a lot more horses into their S3 chassis. Tom:seeya:

I have some Clubman chassis in a container due to arrive in Houston on the 27th, thinking one of them might need an Ecoboost, I want the drag race christmas tree next year. Also working on a Miata gearbox fitment as a T9 alternative.

That looks like it took a LOT of packaging to make it all work. I wondered why this project was taking so long. Now I can see where you were spending time.

 

Wider rear tires probably needed IMHO. Or will you keep a square set up?

It sure doesn't like bumps! Power is crazy (in a good way). I like the idea of finding a substitute for the T9 transmission as it is harder to service and seems to be getting rarer as it ages, unlike the Miata transmission. I am impressed with the effort you are putting into this Ecoboost model. Seems like it might be hard to fit it all into the engine bay of the standard chassis? What do you estimate turnkey cost will be?

[Tbox56]

There was a lot to fit in the engine bay as well as making the steering column dog leg around the intake, new motor mounts, new alternator mount, fabricate an intercooler and all the tubing, Ford throttle pedal mount fabrication (the eboost is fly by wire), additional air venting in the nose cone, fabricate larger muffler and more. Will have 195/50 15 tires on the front and 225/45 15 on the rear, 7'' wide front wheels and 8" in the rear.

 

The camera movement is from it being hand held by a brave volunteer sitting on 2 moving blankets without a seat belt where the passenger seat will go. No plans to try a classic size chassis. A turnkey car should be in the low to mid $70's

You can get a similar package from Westfield:
