Raceco

Raceco design Duratec valves. 36.5 mm inlet and 32 mm exhaust for maximum flow and power. The use of these valves allows for unprecedented airflow figures. Require new valve seat inserts. Material exceeds 21-4N. Plasma nitrided. Valves have no undercut to improve strength and flow and are intended for high performance use. As used in our 300bhp engines

£20.00 + VAT each

Uprated valves of the same quality as above also available in stock 35mm and 30 mm sizes. Recommended for high rpm use.

£20.00 + VAT each

Split collets for above £1.00 + VAT each

Roller throttle body & ported Duratec head being tested on Superflow 600 flowbench.

Raceco have tested every type of cylinder head and throttle body combination currently available.

We have found that our 54mm throttle bodies out-perform every other induction sysyem on the market on a properly ported head. Hence the high power figures we have been obtaining.

Projects under development. Raceco 300 bhp 10,000 rpm 2 litre.

Raceco UK have built more different capacity and different specification Duratec engines than anybody else in the UK and possibly further afield. Raceco are the only engine builders to have tested 300 bhp + engines in three different capacities, 2.4, 2.3 and 2.2 at the Emerald rolling road run by Dave Walker. The Emerald rolling road is used by many Caterham owners and so it offers a direct comparison with other makes and engines from different suppliers. Nobody else has yet to test a 300 bhp 4 cylinder engine at Emerald.

Please note that engines can be built to the specification the customer requires, not only to the above specifications. 26 years of building engines to the highest level means that Raceco take the guess work out of performance engine building.

To see some dyno graphs of Raceco engines please go to www.dyno-plot.co.uk go to power-run graphs and type in Raceco in the search facility. Power graphs can be over-laid to compare different engine specs. You can even overlay engines form other manufacturers but to be fair only engines tested at Emerald will give a true comparison.

NEW! Raceco 2.2 crankshaft

Raceco design 88 mm stroke low inertia crank. High rigidity, 300 bhp 9,000 rpm capacity. As used in our 2.2 conversion. Both 2 and 2.3 litre engines can be converted with rods to suit. To be used with our Raceco design 89mm pistons.

The Raceco 2.2 89x88 over-square engine is a great compromise between the 2 and 2.3 litre engines giving good torque, power and revability. Top quality UK manufacture by Arrow Precision in Nitrided EN40B. Manufactured to exclusively for Raceco UK.

Crank and rod set £2,600.00.

Due to our exclusive design no photos of this crankshaft will be published.

N.B. For the 300 bhp + engines including the Raceco 2.2 we still recommend Arrow as their quality is unsurpassed.

NEW! NOW IN STOCK

Raceco design 54 mm direct to head throttle bodies. Manufactured by Jenvey exclusively for Raceco UK. These throttle bodies are the development of three different prototypes that have undergone two years of engine, flowbench and dyno testing. Out flows both our 52 mm parallel and 52 mm taper designs with the convenience of being direct to head and not requiring a separate manifold. Also out flows the roller bodies tested. They have the added bonus of being affordable as the one-off prototypes were extremely expensive to manufacture.

These are an essential requirement for high output engines and work extremely well with both a well ported Focus head or big valve Focus or Ranger/Mondeo head.

Don’t be fooled by engine builders that have never built a 300 bhp / 75 bhp per cylinder engine that say that these throttle bodies are too big. They are still on the small side in comparison to a World Superbike Honda or Ducati twin that run throttle bodies in the region of 60 to 65 mm per cylinder! In fact our top of the line big valve head loses 1.5 % of flow when these bodies are fitted so bigger ones may be on the ways soon! 54 mm still offers excellent driveabilty and idle.

N.B. these throttle bodies will work only on a well ported or big valve head. They will be too big for a stock or badly ported head.

Throttle bodies shown in photos are prototypes. Production items will be black with "O" rings at gasket face with additional bosses for top mounted throttle linkage
