DVA Power is a small company setup and run by Dave Andrews undertaking engine tuning and building, it is sited in Milton Keynes. Most popular engines are catered for but it specialises in the Rover K series engine as fitted to the Caterham Se7en, Lotus Elise, MGF and Rover saloon cars. DVA Power offers a number of off the shelf K series upgrade packages  from 135 to 190BHP. Bespoke tuning work with a proven track record  to over 280BHP is also available at reasonable prices.

DVAPower currently holds the outright power records for K series engines at the Emerald rolling road at 1700, 1800 and 1900cc, the DVAPower entry in the TunerGP for 2005 won the NA class outright in both ¼ mile and circuit. In 2006 the same car was the fastest NA car on the circuit.

In addition all types of engine work are undertaken including fitting and timing of cams and verniers, fitting of ECUs, fitting of throttle bodies and airbox kits, fitting of proven engine upgrades, fitting of forged pistons, full engine rebuilds and tried and tested cylinder head porting for bespoke upgrades.

All prices shown on these pages are what you pay, there is no VAT to add although there will be some postage and packing.

Some of you may have already seen the K series engine page.

Due to increasing porosity problems with poor quality K series head castings which have been given to me in exchange I have revised the way I offer an exchange cylinder head service for kits which include a modified cylinder head. Customer heads will be accepted on a provisional basis, if after refacing they prove to have damage/porosity issues or are insufficiently hard then a surcharge will be made and the head will be returned to the customer.

Jenvey Dynamics direct to head (DTH) throttle bodies



Jenvey now to produce dual throttle bodies which bolt directly the the 'K' series cylinder head, the barrel spacing is the same as the port spacing on the head so they offer perfect port alignment and also do away with the need for a manifold. These are absolutely ideal for the engine and with a little modification and some small brackets can take the standard fuel rail pressure regulator and injectors. They are 42mm in size which has proved adequate for over 250BHP. They offer the simplest, cheapest and most suitable induction system for the 'K' series engine. They offer far better idle and progression than some other direct to head systems due to the very short distance between the throttle plate and the inlet port.

Shown below is a picture of a pair of the bodies attached to a 'K' cylinder head, the only modification necessary is the mounting of the water jacket takeoff on the front body.

Cold airbox kit for direct to head bodies


To complement the direct to head throttle bodies Auto-Teknix (Bernard Scouse0 have produced a complete cold airbox kit to fit the Lotus Elise / Exige and the Caterham seven which allows retention of the standard fuel rail and pressure regulator, or fitment of the Jenvey Fuel rail without needing spacers. it contains everything you need including the airbox, a throttle linkage, trumpets, backplate, trunking , large Pipercross cone filter(Elise/Exige only) and all fixings, it works out around half the cost of the equivalents. Below is a photograph of the Elise airbox kit fitted to the DTH bodies, it could be adapted if necessary to fit individual TBs or other types. The details of the kit are shown below the picture. The Caterham version has the air pickup facing in the other direction and has mouldings to clear the chassis member and clutch cable but is otherwise identical.





The main features

Complete kit, includes air box, air filter (Elise/Exige version only), GRP trumpets , backplate fuel rail mounting, throttle linkage bracket, trunking and all fixings required.

Enables the standard K series fuel rail, fuel pressure regulator and injectors to be used without needing an external pressure regulator, which is adequate for engines up to about 210 BHP. Can also be used with the Jenvey fuel rail with minor modification, and does not need the 20 mm spacers.
I
n the Elise/Exige  installation, ducts cold air from the wheel arch intake directly to the engine and only intrudes 10 mm into the boot space.

The airboxes clever design allows retention of the existing fuel rail and integral pressure regulator thereby saving the cost of a new fuel rail (£48+VAT) and pressure regulator (£50). The throttle cable mount bracket (free with the kit) saves the cost of a throttle linkage and mount (£103+ VAT) and the composite trumpets supplied with the kit would be approximately £100 to buy separately making the kit extremely good value for money.

Appearance is excellent. and it can be removed in a couple of minutes.


The kit consists of

• Airbox (red or black but other colours are available to special order at £20 extra)
• 4 off 43 mm bore x 50mm long or optional 90mm long GRP trumpets
• Backplate plus fixings for above, (includes fuel rail mounting for standard K rail)
• Piper 7004 filter (suitable, for up to 385 BHP so no problems there !).. Elise/Exige only)
• 100 mm diameter Aluminium flexible ducting (stretches to about 600 mm)
• 100 mm to 83 mm filter adapter
• Air filter bracket to mount filter in wheel arch (Elise/Exige only)
• 2 x 100 mm hose clips
• All studs, nuts, bolts, washers etc included to enable an easy fitment
• The air temperature sensor fits into the backplate
• There is also provision for a crankcase breather pipe connection
• Included is a throttle cable bracket that enables the standard Elise / Caterham throttle cable to be easily used with the direct to head body throttle arm.

Price for Elise/Exige kit £395
Price for Elise/Exige kit less filter and trunking £360
Price for Caterham kit £350
