Does Ramair Proof Exist?

[HansO]

I was hoping that somebody had dyno'd a stock Rocket then added the Ramair kit and done another run. Just looking to see if they will generate some extra performance with a stock exhaust. I am assuming that a custom tune would be required (something more that the "12 Minute Tune"). When I look at dyno records for modified bikes it is really not comparing apples to apples as they relate to a stock Rocket.

to gain power from putting in you also need to allow out so you really need to tune a bike with an higher performance exhaust system already fitted then compare.
just adding the Air in will still be very limited by the over restrictive std exhaust

I'll repeat it one last time for those that don't seem to be able to read. It's been done by Neville Lush for @Mike188 I think. Dyno printout has been posted, from memory just over 20hp with Ramair and Lush tune. Nothing else.

I was wondering if the intake was more restrictive than the exhaust so that if you improved the intake side then you would get a power boost up to the limitation of the exhaust.

The post I read from Neville was with the Ramair and the Lush tune on a bike with a pipe and he wrote that there was a small drop in power compared to the previously install K&N filters (which I am assuming made more power than stock).....Not sure if you are referring to the same post but I have included the one I was talking about below.


From Neville's post....
I am not about to get into a pissing match about a set of air filters. I was asked to see if these filters were as good as the little K&N's which go under the bearclaw. This is because many folk wish to retain the bearclaw. I tuned a bike with exhaust and RU1770 filters( which are much better than 2780s), then fitted the Ramair as a comparison. I checked the tune of the bike and it did lose average of 2 ftlbs and 1-2 hp across the range. To me that was a very GOOD result. The Ramair filter is better then the little K&N's and fits under the bearclaw well. A week or two later I had a customer with a classic with Jardines of the day on it. I fitted some street cams to it and a Ramair filter and tuned the bike. I have done quite a number of these bikes with Jars and K&Ns or Unifilters, under the claw, and never gone over 169hp with that combo of parts, so to get at least 3 hp MORE while still retaining the bearclaw, that again is a good result. The exhaust is what holds back the numbers in that combo. I am sure it is not the most high performance filter on the market, but I believe it is absolutely up to what it was designed for/to do. I made the effort to do this partly for you guys here and partly because the Ramair guys sent me one to test. So it is tested. Merry Christmas to all, have a safe one.

Nope. I thought my post was easy to understand.

 

[bruce aussie]

Yep just re read both my posts and I could understand both of them.

even small changes to exhaust like fitting TORS are accomadated by the std intake but still limited to what it can draw so adding a Ramair WILL improve

The K&N RU1770 filters are about twice the size of he 2780's which fit under the bear claw the 1770's will not and neither will the slightly larger Flowing again RX-4040-1 which I run.
So what Neville is saying is that the Ramair Which Does Fit under the bear claw allows almost but not quite as much as the K&N RU1770 but a LOT more than the K&N RU 2780, the whole exercise of making the Ramair was to make a Higher Flowing air filter that Will Still Fit under the Bear Claw which it succeeded in doing, Ramair had been asked by one of our members (I forget who but Chris @barbagris could tell you) to make a higher performance filter that would fit under the claw, I include a couple of pictures of my 4040 to show the compromise needed to make otherwise the second shows the strap which has an out of sight strap to the centre throttle body which is needed to keep them safely on there the bottom picture is of the view from the seated position, while I love the in your face look I would have gone for a Ramair had it been around when I was doing my mods, In my opinion the Ramair coupled with the OzClaw made by Les @ozrider is the Bee's Knee's in looks and function

Your's certainly looks very good but I can see the compromise between comfort vs performance. The original question I was trying to find an answer to was if you add just the Ramair and a tune to an otherwise stock Rocket will it make more power an if so how much. I realize that the Ramair will flow a ton more air than the stock intake but if the stock exhaust is so restrictive the engine can not use the extra air intake it will not take advantage of the extra air flow and not make any more power (but that the engine make have other benefits like being more free revving at lower RPM etc)

long legs and I got used to them sticking out not a real issue I was just illustrating the advantage of the Ramair not taking up so much space whilst moving somewhere near as much air, In all honesty I was planning on going the whole hog with pistons, cams etc but financial position changed with wife not working any more so maybe just maybe it might still happen well down the track ... have wait and see

I find it odd that anyone can realistically expect just a filter change to add substantially to power output. The only dyno figures we have include a Lush tune. I would say that almost all of the increase in power is attributable to the tune. The filter perhaps is freer flowing but I'm yet to see anything conclusive that says any filter change adds power on its own. Ramair seems to be a great option for anyone wanting to also add exhaust, do a retune AND retain their bear claw. Simply putting one on without doing anything else would give you the benefit of a serviceable filter but very little increase in power if any.
