Until I see comprehensive DYNO testing :dontknown the competing filters my next filter will be a stock one?:hun:
The GREEN FILTER line had to go through independent lab tests to be approved for FORD, Chrysler, B&S as well to prove they met their requirements. I will see if Jason can get me these?
Also as we speak here Two Bros is using one of the new NMN GREEN FILTERS for the the RT to write one of the programs for the new RT Pro Juice Box unit they are making ,and they will be making it one of the pre-programed settingscontained in that unit along with ones for their pipe.
Once Two Bros is done with their programing and testing I will see if they will let me have a copy of the Dyno reports for their pipe and Pro series Juice Box with and without the GREEN FILTER filter.
I am not sure just what HP increase an RS or RT will show with these filters, but a HP increase from this kind of filter has been Dyno PROVEN time and time again in real world Dyno test on so many different autos, bike, trucks ATVs that there is no reason to doubt that the engine in a Spyder will not respond the same as all these other engines have over the years.
In todays "sue happy" world, companies like K&N and GREEN FILTER would have been called out on this long ago if they could not back the claims they have made throughout the years regarding the HP claims made on other internal combustion motors.
There is a reason MOPAR uses these for it's factory high performance filters and that the HUGE money Saleen equiped FORDS use these filters as well. When a large part of the price of a 67K plus Saleen Mustang or truck is because of the motor, the last thing they are going to do is use a filter that makes the motor wear faster or reduce it's power putput.
Because the Spyder is somewhat different in it's VSS system and reverse trike design, it has not been Dyno tested as quickly as many other bikes/autos/ATVs have been. So right now these test results are not so easy to come by.
But there is no reason to doubt that 990 series ROTAX motor in a Spyder would respond any different that any other internal combustion engine does when using this type of high flow filter.
There is no filter that will make a Spyder into a top fuel drag bike, but all around performance is not just about top HP numbers. I have been doing this on bikes now for 39 years, and there is no doubt in my mind that the RS Spyders and the RT have much improved responce and all around performance when one of these filters is used.
But, if you like paper filters by all means keep using them. Your using or not using them is a personal choice you are free to make, and one I'm sure seems to make sense to you to do so. :thumbup:
