StephaneM Posted March 16, 2003 Share Posted March 16, 2003 Hello, I own (from yesterday) an HPC Caterham wich is called VXi I think in GB. I had spare parts with it (it was a racing car) including a new bonnet wich is a VX one, with holes for carbs air filter. Is there a kind of air filter to use on my VXi wich fit the hole, like JPE ones? Thanks in advance. Stéphane in France Link to comment Share on other sites More sharing options...
I reply to every thread Posted March 17, 2003 Share Posted March 17, 2003 If it is a VXi then you shouldn't have a bonnet cutout - all the injection set-up fits under the bonnet without the need for a hole. I can't imagine how you could have a side filter with a single pull injection system? It looks like you've got a spare VX carb or X-flow bonnet. I have a PiperX cone filter for a VXi injection if you're interested. (Was this standard fitment?) Link to comment Share on other sites More sharing options...
Nick Pargiter Posted March 17, 2003 Share Posted March 17, 2003 Stephane To use the other bonnet you would need to change to carbs or throttle-bodies to get the JPE look. The standard system uses a Rover air filter housing fixed in front of the heater and breathing through a small hole down to the tunnel above the gearbox. If you are interested I also have a Ram-Air filter and pipe that was fitted to a VXi. When used with a Programmable chip( also available ) and a performance exhaust( not available ) I got a 15% increase in power and torque. The chip is already mapped for a Vx powered Caterham so would not need setting up. If interested e-mail me. Regards Nick Link to comment Share on other sites More sharing options...

" Being pedantic here ..............but he probably does not know what cutout he has. JPE, X-flow, Jenvey TB's 🤔 🤔 Link to comment Share on other sites More sharing options...

I reply to every thread Posted March 17, 2003 Share Posted March 17, 2003 "Vauxhall bonnet" They're all the same on a de dion as far as I'm aware. I only make the point having seen someone try & fit a VX bonnet to a X-Flow after thinking that the cutouts were all the same Link to comment Share on other sites More sharing options...
StephaneM Posted March 17, 2003 Author Share Posted March 17, 2003 It's a fact that I'm not sure... The guy who used the VXi for racing (the car won the french serial GT 2000cm3 cup last year) had another bonnet in stock unused... with one hole... I'm going to try to check with pictures...
