Big power Zetec

Having finished building and mapping a Ford Zetec Puma with GT30/76 on Emerald ECU.
The engine has been built with Wisco pistons and K1 rods, it has a Sitech ported cylinder head with std black top valves and stage 2 cams. The Puma also has a straight cut box with dog engagement.

Happy with the power 26psi giving 481bhp

So after a late night of car building and dyno testing we have found out the following - 

Car - Bens focus RS fitted with Revo stage 4+ was a 425bhp car, we then fitted our stage 1 cams, the gain was 20bhp neting him 445bhp but boost was struggling to hold 20-21psi due to the new air flow requirments of the cams. Basicaly the standard turbo is now maxed out.

We also fitted water/meth and continued testing this also gained us 20bhp on top of the cams, boost remained the same (normally with water meth you see an increase in boost) but power had gone up another 20bhp.

So end result is 462bhp or 418whp at the wheels. Happy with that.

But the cams also net you far larger spread of torque it hold peak torque for almost 1000rpm longer
Also it makes the same power through out the power curve but continues climbing for another 1000rpm so peak power is now 6300rpm but still same power as old peak at 5300rpm.

Epic Russian Focus RS Build

On morning of October 15th we came into the workshop to find we had an epic task on our hands! 

the first move was to get the car firmly planted on the ramp and get tearing it to bits.

By the middle of the first day we had the full engine & gearbox setup sitting on a trolley

Next task was to get the gearbox off and get the engine onto a stand for forging! At the same time the head and sumps were stripped off to remove the pistons and rods

The pistons and rods were next to be built up and also the gapping of the piston rings

The block came back off the stand for cleaning, was refitted to the stand and built back up with the following

Forged Pistons

Steel H-beam conrods

Arp conrod bolts

Sitech spec Custom camshafts

One of the next tasks to do on the engine was to fit the new exhaust manifold and most importantly the TURBO!! 

The engine was lifted off the stand and put back on the trolley to fit the custom clutch kit.

Gearbox was the next part to be fitted back on

The engine was fitted back in all that was left to do was fit the wiring loom and a few other things. Not much to do!!

After a few hours driving and testing it was time to put the car on the dyno and see if the 500bhp figure the customer wanted had been achieved!?

The Final figure achieved on the car was 535hp @ Flywheel!

Our Russian friends were very happy with the outcome

They have since visited other dynos and achieved 550hp @ Fly :) 

2012 test

Up and running

Sitech Racing has now moved.

Sitech Racing has now moved to a more centel location.

Sitech Racing, Unit 4D Barham road, Rosyth Europarc, Fife, KY11 2XB.

We have just moved but all facility are up and running.

The rolling road has been relocated to new purpuse built sound proof (almost) booth.

On a different note here are a couple of dyno graphs from a couple of cars mapped by Sitech Racing.

The first graph is from Veg's Honda Civic B16 running on Hondata ECU mapped by Sitech an impressive 217bhp

The above Supra suffered with over heated tyres and grip issues still recorded 673 bhp at 21psi of boost. The car is running on Haltech E11 ecu mapped by Sitech.

ST225 fitted with Sitech Racing inlet shows 34bhp gain

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.

Tomorrows shipment of shiney Sitech Racing inlets

A selection of inlets been shipped tomorrow.

Ford Focus XR5, ST225

Here are a few pics of a happy customers car from Australia.

He has fitted a Sitech Racing inlet manifold to his Ford XR5 (ST225 in our language).

Car spec - Uprated IC, Dreamscience CAI, Quaife, Miltec turbo back, RS plugs, RS plugs, Sitech Racing inlet, Forge act, Forge dump valve, std turbo.

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.

Sitech Racing and OZ alloy wheels

Sitech Racing is proud to announce a tie up with OZ Racing alloy wheels.

We are now able to supply the super light weight wheels like the Alleggerita below, for the Ford Focus MK2.

The full OZ range is available

2.0l Zetec turbo hits 505bhp

Above is a graph and a car Sitech Racing and owner Andrew have put together.

New stock of Sitech Racing inlets

I am pleased to say that the next batch of inlets are now in and awaiting despatch.

We are currently undergoing a forged engine build on the company demo car, in order to push the development of this vehicle farther.

It spec list includes a GT35 turbo to run alongside the Haltech managment that it currently sports. Also a nice set of AP brakes and a new Helix clutch assy.

Focus RS and ST inlet manifold details

The price of the inlets have now been finalised at £695 inc vat.

Thare are also powder coating colour option available, black, white, ect.

Inlet manifold dyno graph

So here is a graph from a customers car from an independent dyno.

Car is a Focus RS running a JS400 kit and a Sitech Racing inlet.

The graph displays power at the wheels.

More impressive gains

So today we have fitted another Sitech racing inlet manifold to a customers JS400 equipped car and again have seen an increase of 44bhp and 30 ft/lbs of torque.

I must remember my camera next time.

Focus RS inlet manifold results

So having done some direct back to back testing of the standard Focus RS inlet manifold and the Sitech Racing inlet manifold, I am pleased to say that on 2 cars running a JS400 tune we saw a 46bhp increase.

Standard manifold 397bhp
Sitech Racing manifold 443bhp

Focus RS cast inlet manifolds are go

The pictures shows a development item. ie. finish is incomplete.

Over the last 4 months Sitech Racing has been developing a cast aliminum inlet manifold.

The manifolds are produced here in Scotland (none of your China stuff).

So a summary of the inlet - CFD designed with a 15% increase in volume to aid cylinder filling, a tapering design to aid air speed towards the 5th cylinder, the inlet will not explode like the standard plastic ones, the inlet is a direct bolt on with no modifacation required and comes with all fittings.

Knockhill with the Focus RS

Just a note for all those people with a Focus RS considering a tune or anyone who fancys a FRS.

Sitech Racing will be attending the track day at Knockhill on Sunday 18th July and is happy to take anyone round the track in the passenger seat of the JS400 tuned FRS, might even switch the nos on. Just ask me (Simon Smail) on the day.
