SIDECAR racer Dave Holden is in hot pursuit of the EMRA and Aintree Championships -- thanks to a new radiator set-up on his Ireson-Honda.

After experiencing overheating problems this season, the Great Harwood-based multiple champion experimented with a new cooling system at Mallory Park.

And the results were impressive, with Holden and passenger Graham Holgate winning both six-lap races -- and recording the fastest lap -- at the Leicestershire track.

"We've been suffering from a loss of power all season because the engine has been running too hot," explained Holden.

"But by putting a bigger radiator and cooling pipes in, we've reduced the 90-degree temperatures by 20 per cent and the difference was obvious straight away.

"The engine is much more responsive and will certainly make a difference on the faster circuits where power is at a premium."

Favourite to retain their EMRA sidecar title, Holden and Holgate are on Mersyeside this weekend chasing points for the prestigious Ace of Aintree series.
