Forf Focus ST225 and Sitech Inlet

So today we have fitted a Sitech Racing inlet to a modified ST225 2007. Again shows very good numbers.

The car was fitted with FRS fuel injectors, hybrid turbo, aftermarket cooler and exhaust.

The car was put on the rollers and recorded an average of 318bhp then we fitted the Sitech inlet did some running and retested, the average power of the car was now 352bhp, thats a 34bhp increase.

On the road the customer reported a smoother power delivary with more top end pull.

New Evolution 2 Inlet manifold

We have just recieved the Evo2 version of the Sitech Racing inlet manifold.

Features on the Evo2 version include a repositioned servo boss, that enables an easy fit on the Focus ST225. Also we have an improved surface finish on the casting.

The new rrp on this is £548.94 plus vat for a bare ali finish or powder coated white or black is £40 option.

Standard Focus RS with Sitech Racing Inlet manifold

So we have finally fitted a Sitech Racing cast inlet to a standard Focus RS.

The car was a completely standard 1500mile example.

The RS was put on our rolling road first of all, where it produced 288bhp slightly down on the book power. We then fitted the Sitech Racing inlet and re-tested. The end results showed a gain of 12bhp, but the power delivery was much improved with the gain in power from 4000rpm right upto the rev limit, with a far less pronounced power drop off at 4500rpm.
