ramair cracked

[warp9.9]

Scott - Actually I'm not sure there is room to get the OEM stacks inside a foam filter that fits under the claw without them getting deformed by the foam. There is not a hell of a lot of clearance twixt RAMAIR outer and the claw and the OEM rubbers are cut away to avoid touching the much thinner Triumph plenum wall. I'm not sure - but I think this was also discussed when Colin talked with RAMAIR. The Ramair has radiused inlets - but iirc the "bell-mouths" would not fit. In teh Custom ITG Colin had made (which I now have, and I think you had for a while) the bell-mouths JUST fit in but there is not a chance in hell of it fitting under the claw.

That Piper-cross does look familiar does the base plate resemble this?

or does it have the custom OZ stacks in it.

Looks much like Duncans and when we worked it out on the Tech site.
The extra piping he had to put on top to get her tucked away more was not thew way I wanted to go which is why I went with the OEM stacks

Its all a compromise of looks and versatility. I designed mine with the max air flow in mind as it would have probably been a Carpenter motor under the filter. Anything less and I would have gone with a size or two smaller.
Now as for your firewall idea I think its a great one as it will keep hot engine air down. The only thing I would do different is relocate the coolant tank and plumb some cool air ducting from up front to feed the filter more especially if I was not going to do any bear claw cutting.

Now that I am thinking about it I do remember Colins touching base here in the USA for me to take a look see and possibly test but Gracie did not live thru Canada so on in the mail it went. I believe you are correct it was a ITG brand and well put together. I think I would have gone with alarger one but for a stock or stock with pipes motor it would be great. And yes I believe you are right it was to short to go with the OEM stacks. The one I chose before I knew if ITG was 150 mm tall. and they had a few other various height and width choices.

I'm lost with all this! I have the RamAir system since early last year & have had no trouble, it works well & has given me an additional power boost but I can't remember now how much BHP it was. I do remember fitting it & finding difficulty in holding the filter down while tightening the clamps, if they lifted & I had kept tightening I would have encountered the same problem with splitting as the clamp pulled down on the rubber above the bodies. The tie down idea sounds great, wish I'd thought of it. Now I don't mean to say that you guys have fitted it wrongly, just saying that my experience tells me that it's easily done, maybe due to poor quality I don't know but I do think it can be improved. As for the stacks that are discussed I haven't I clue what it's about, I thought the length from filter through throttle body was critical. I have no idea about the technicalities of the intakes over & above that more air in = more power out, so I am always up for learning. Thought it a good response from RamAir though.

Excellent response, Good to see.
Be interesting to see if it were just a bad batch of the silicon rubber, Lets hope so for those that have gotten them. I would have gotten one had I not already bought my K&N 4040's as I thought it was a good idea

I bet your set up looks better so don't sweat it.

Checked my RAMAIR today, all ok. It's been fitted for about 4000km.

Well sort of.
To get it to fit without those angled rubbers and use the triumph trumpets - it had to be custom made (I think Colin made the baseplate) and ITG glued the filter on.

Baseplate is approx 4.5" by 13.5" and about 3.5" high at the dome.
Substantially smaller than the standard base plates.

It is VERY VERY LOUD. Easily audible above wind rush and exhausts at 100mph. With a full face helmet and earplugs. i.e. FUN but more than a little wearing on longer runs.

barbagris, interestingly those "restrictive" filters socks from UNI-Filter actually make more power than the RAMAIR on my dyno. I find that flow testing filters is not the same as putting them on an engine. Relating to all the above posts, I note how folk are quick to hang shyte on the supplier within minutes, every one has a bad day or bad batch,whatever. I've had allsorts over the years. Surely how they respond to a problem is important? If they sent a new one out thats good. I had trouble with the RAMAIR coming off, with the first time I fitted one. Not since then, after I worked out how to do it, have fitted about 8 to 10 I think now. I tend to agree, they should have a rib inside the rubber to match the stock TB, although no K&N's etc have. I did send them a email to that effect. I have not ripped one yet, the rubbers seem quite good, so maybe gibbon had a dodgy one. Also interesting Scott/Warp, that you are putting another turn into the inlet tract with the above adaptor, but don't like them in the exhaust . Hows the shoulder doing? Having the op soon? Happy New Year.

Just wondering what testing you did in forming that opinion. Don't get me wrong, I reckon making use of the stock plenum and associated clamps and bell mouths in this way makes perfect sense and seemingly would be a more robust and better fitting product than what Ramair put on the market. All the talk about better flow is fine but I'm wondering if that should be an end in itself. Doesn't there just need to be enough flow? More important than theoretically better numbers would be a product that stayed on and didn't fall apart. I'll be interested in seeing if Ramair makes any changes to its product.

I went the standard plenum after seeing what @barbagris had done with the foam setup but I cutup a BMC filter panel (similar to K&N),
I mainly wanted to keep the stock bellmouth and the rest of the system is still all there, sure its a pain to refit but I'm used to it.
I had it dynoed with this setup on

That is VERY GOOD TO KNOW, Nev. I wonder why Piper and ITG recommend against using their filter socks then? - I know - probably to sell the bigger expensive ones!

Do you manage to fit them under the claw? - Would make them a VERY GOOD option if so. Like I'd order a set to try! - they're cheap.

Are the new UNI's multi density foam? - Asking coz I don't know. I had UNI filters on a Laverda back in the '80's - They were a sort of green colour and single density - The Laverda came with open stacks and seemed to like sucking leaves in. Piper socks are 2 layer - ITG socks 3 layer and Ramair do some 2 layer socks too (if pressed).

The uni's come in green and red, mostly. Single density, bit sort of agricultural the way they zip tie on, but they do let air in, the ramair is a neater setup. I mostly get red ones because red is a fast color.They do fit under the claw easily as they bend a little etc.Surely this is OLD news!! Folk have been using them for 10 years FFS. I had one of the 200, 1200 Mirages that were a 30th anniversary special, black and gold all over with Lafranconi 3:1:2 exhaust on it, Jota cams and Goldline brakes of the day. It was a nice old jigger. 1978 model I think , last one before the 120 crankshaft, so it sounded proper . Quite light for a 1200 at 212kgs. I had to sell it due to lack of domestic bliss, which was a pity as it was a good toy to have and (once the fuses were replaced) a solid reliable fun bike, although slow by todays standards.

If your talking about this picture

Its Duncan's Roadster He tried several different mounting types to include the velocity stacks. He was trying to keep the filter in tight. I went for the straight mount using the OEM stacks on mine as I did not want to add any length between the filter and the throttle body.

here was my final look.

ANyway the shoulder is hurting pretty good I had the surgery Friday. The Supraspinatus tendon was torn completely off the bone so more work had to be done then originally planned. 3 hours on the table and now for recovery. Thanks for asking Happy New year to you and yours also.
