Hi I am looking for some oversized ram air tubes for my 1098. I have seen loads on the internet but there for the race fairings not the road fairings. I dont want them in carbon fibre as there not seen. Fibre glass will be fine or does anybody out there open up the standard air tubes to 38mm I think? heard you get 5bhp from this alone as it lets more air into the 1098 engine. thanks
I have read that the intakes restrict air flow into the engine on a 1098. It's nothing to do with the ram air effect. It's the diameter of the tubes that's to small. If you look at the race air tubes there a bigger diameter than standard. A guy on another forum tested them on the dyno and just changing the air tubes gave 5hp not bad for a simple mod. There is a way of heating up the standard ones and put something down them to make them bigger. There's just one point at the front that to small.
Not sure about fibreglass, i know EVR make some larger items in carbon fibre, but they may only be compatible with their enlarged carbon-fibre airbox. MWR air filters fit better than the OEM item, and are well worth buying (one filter per side) - Heard a story about the OEM filter, and if it doesn't sit/seal right on both sides it can cause an imbalance/vaccum between the left and right hand side air tubes, robbing the bike of power. That might be your first point of call - Possibly. May not have much truth in it - But well worth checking out all the same. But yes, if you do find any fibreglass ones, i'd certainly be interested too.
I have fitted the mwr 2 part filters this week. Not had chance to test it yet though. Think I will buy a second hand pair of tubes and see if I can make them bigger. I have heard it needs to go to around 38mm. Big change on standard so I wouldn't want to damage the set on my bike.
