Today we got in Drew ST225 already running a file, FMIC, Miltec downpipe and backbox and K&N induction kit. The car made 282 bhp on the dyno. We then fitted the Sitech racing inlet and Miltec de-cat ran the car up a few times then retested. Results showed a good 34bhp gain to a new 316bhp.

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.
