really? mine is a straight tube w/ a small radius turn. i beleive Orange's was as well til the raceline water rail was installed. many others too, thats why I think its a new design. Its the rubber S connecter hose that really caught my attention.

Thats interesting. Now that I am back from slaying muppets in the office, I just checked to and the installation on mine is identical to this one. The photo does not really show it well but the S-bend kicks the pipe up and over the steering column. I have a 2004 kit so it must not be too new a design. The S-hose is a standard ford focus part from the hose kit sold by ford dealers (I know since I replaced it 2 months back). I also checked a few other Seven & Elan previously sold cars on their website and they seem to have the same on the SVT motors.

 

Just a thought - it is not a thing just for the SVT motor compared to the regular Zetec? I doubt it but stranger things have happened...

The BRG STV is no longer at Sevens & Elans.:nopity:

 

Its now parked in a garage, next to my Elise, and turbo Miata!:drool:

 

After buying the car, it was trailered to Fastrack Automotive (and magically appeared on their Facebook page) for upgrades, while waiting for the road salt to clear. The car was also taken to SV Engineering for dyno tuning, and SV Engineering placed videos of the dyno runs on their Youtube channel.

 

I've added a third brake light (for inspection).

 

I discovered that Caterham's SVT engine installation deletes the factory oil to air heat exchanger, and uses a standard Zetec oil filter in place of the larger unit that is standard on the Focus SVT (all to clear the motor mount on the passanger side).

 

This has been corrected by adding a remote oil filter kit, Caterham front mounted oil cooler, and thermostatic cooler bypass valve. Now I use the (larger) original Focus SVT filter.

 

Adjustable spring perches are being added (backordered!) to raise the ride height slightly, as my lower control arms are not parallel with the ground, but slope upwards to the wheels, and I frankly need a little more ground clearance for the speed bumps in the parking lot at work.

 

A lot of work has been done to make the ECU happy, so it will pass state OBD2 inspection.

 

I warned my Wife, its loud, the ride is stiff, and just about every other thing I could imagine to try to keep her away from the car. Basically all the things I tried to tell her when I bought the HRM Special Elise.

 

It didn't work. She loves riding in the car.:banghead:

 

Thats the second time I've been totally disappointed by a Lotus design, in exactly the same way.

 

Just over 750 miles on it now.

 

Fastrack is having a Lotus suspension setup day on April 3rd, and the car will be making an appearance there, weather permitting.:driving:

Congratulations on your new purchase and welcome to the site! It is a lovely looking car.

 

Your post was very interesting for a number reasons:

 

I discovered that Caterham's SVT engine installation deletes the factory oil to air heat exchanger, and uses a standard Zetec oil filter in place of the larger unit that is standard on the Focus SVT (all to clear the motor mount on the passanger side).

I am interested in why you felt the need to change from the standard Caterham intallation - were you getting hotter than normal oil temperatures? I have the same engine in my car and fitted a oil temperature gauge last year to get a good read on temperatures because of the same question I had on the standard installation - a little hotter than expected against the standard Focus SVT installation but still in the acceptable range. I had tossed around an oil cooler and the remote installation but for now have left it in the wish list because I could not see the pressing need. I am not tracking my car so that may have been a factor in your thinking.

 

 

A lot of work has been done to make the ECU happy, so it will pass state OBD2 inspection.

 

Does this mean you have set up all the sensors so that you can just plug in the OBD II and get zero faults? If so I would love to learn more about this experience. This was a total PITA when going through the registration process in NJ and there are a few people around NJ who would love to know the secret to this.

She is special! Damn - where did you find her!! Caterham do not offer that form of upgrade in their catalog of options :)

I also would really like to hear about the work arounds that were done to make the ecu "happy" our car with ford ecu calibration RLA6 runs great but will not pass emission test in ohio. ecu tries to read sensors that do not exist and throws cel codes P0443 & P0453. related to carbon canister & gas tank pressure sensor. we registered as collector car.

CaterhamSVT, how do the power curves look across the rev range? Every SVT powered Caterham's dyno chart that I have seen has a dip in the power and torque curves around 3000 rpm. The tuners and owners with whom I've spoken believe it is due to an airflow restriction caused by the exhaust. Did you find such a dip and, if so, what did your tuner have to say about it?

 

Also, was your car dyno'ed on a Dynojet dyno, or another type?

Hello,

 

Yes Skip, thats my car on the dyno. By the way, I have your sub-frame brace installed on my 2000 Miata. That car is set up with a BEGi Series II+ turbo, factory sport suspension & LSD, FM butterfly brace, single turbo exhaust and free flow cat, AEM air fuel meter, AEM alcohol injection, HardDog roll bar, GoodWin rotors, and Hawk HP pads. The BEGi fuel system allows me to make power and never worry about the CEL.

 

All in all, its a very well ballanced car. Good enough that I don't miss the Elise when I'm driving it.

 

Ok, about the SVT...

 

Power curves, yes, there is a dip, a bit below 3000 RPM. Not as bad as it was with the stock tune. That dip is present on factory stock Focus SVT's. My exhaust system is unlike the SVT Focus, so I do not beleive that is the root cause.

 

As for the oil cooler, Ford's SVT team installed the oil cooler for good reasons. Many Focus SVT drivers add an external oil cooler as well, as do some Caterham drivers with the 2.0 Zetec. Given that the SVT motor has a higher red-line, some form of oil cooling is a good thing. Also Ford uses a better oil filter, again, cheap insurance.

 

In the Caterham, neither of these will clear the passanger side motor mount, and that is the only reason they are removed. I'm more thinking of being stuck in traffic than I am thinking about the track. So adding the oil cooler and remote filter brings the engine back to something closer to what the SVT team designed it to be, with the right oil filter.

 

As far as the ECU work...

 

This is still a work in progress. Once complete, Sevens & Elans will be able to offer an 'upgrade' to make the cars pass OBD2 inspection.

 

There are at least two ways to acheive this. One 'sorta' works, and is fairly easy. The other is a little more work, but might be the 'right' way to go in the long run.

 

Its also possible to do this with the Duratec, but it would envolve tossing the Caterham ECU and wiring harness. But you would have a 'legal' car.
