Hi,

does anyone have a picture of life inside the HRC AIRBOX?
There are spoilers there allegedly have been installed so that no breaks in the gas column.
Has anyone thought about redirecting the intake air, so they do not directly hit on the stacks, but comes from above?

Regards

I've never seen OR heard of HRC airbox for the RC51... However about your question... I think the name of the game here is RAM-AIR to Pressurizing<sp> the AirBox... So as long as you have a GOOD SEAL to make the pressure... does anything else really matter?

You havent? Thats a shame, they are a beautiful part, but Im pretty sure you need an HRC tank to accomodate!

My friend Nick in AU has one and the HRC TB's and velocity stacks to match!!:rockon :notworthy
I got a moriwaki sealed ram air box recently that I have been working on and it is similar to the HRC design in many ways but modified to fit the OEM tank.

Sebastian, I only have 1 picture from the HRC kit manual and it shows no diverter, only a wire frame that held a thin foam filter in place. Ill post a pic up of it later but its B/W and not very clear.

Thanx Jason

I know this picture.
Two independent tuners have told me about it, one of them has seen such diverters in the Edwards bike.
They told me also, HRC has removed the diverters for some photo sesions...
I would just ask if anyone possibly also such a thing has already seen.
Satined it sounds anyway.
I've often thought that the intake air, destroyed the gas column.
When I look at other air boxes that will air very often approached from the top out. As or similar to it is with the oem airbox.
Get me in the winter in any case clamp behind it.

Hey Stunner-Gunner,

Your reply is USELESS, without any Pictures mang., of what You "think" you are talking about!:banghead Hahahhahaa

You know I'm Joking, except for, not having a picture.

Now, a Moriwaki AirBox: those I have actually seen, and I have had a chance to buy 1 acouple years back,.. IF the Moriwaki is a copy of an HRC AirBox....? Then I guess I have seen an HRC AirBox too...

Now My,.:twocents ... Between 2 different AirBoxes...

#1> Moriwaki &
#2> Thorsten AirBox...
I'll Take a Thorsten HIGH Volume AirBox and a TurnOne AirBox, over said Moriwaki airbox, any day of the week and twice on Sunday!

Peace Jeff

OK OK heres the pics:

This is HRC kit, not factory HRC.
They may have very well put diverters into the factory bikes during different stages of testing, but it was never incorporated to the HRC kit.

As far as your preference for the open top box style Jeff, I see your logic but I am hoping that I get better results from the new box then the style your referring to that I sold to afford my new one. The mori/hrc boxes go down lower than the thorsten style, so Id be interested to see just how much more capacity one has over the other.
And yes, I have been told that the Moriwaki family has worked closely with HRC on many engineering design projects including RC51 airboxes, intake snorkles, velocity stacks and clip-ons, so if your looking at a mori part, it might be the same or similar to an HRC part.

Cool pictures... But I was hoping to see Better Quality pictures of "YOUR Set-Up"

:clapper :rockon :woot: Come on now... Lets see them...? Hehehee Hey, can't blame me for trying..

you are not going to get anything with the HRC box that you can't with the Mori and neither of those will outperform thorstens box this has been fact since like 2001

Why do you answer an irrelevant question that didn't even get asked?

The only bikes that even ran the HRC airbox were factory/kit HRC bikes, and those bikes would outperform a modded OEM bike w/ a thorsten box every day since 2001.

As far as a thorstens vs. the moriwaki, 2 words, Dstewart & GPZ11
Name a forum member who has achieved and documented better performance numbers
with a thorsten box than these 2 have with moriwaki airboxes.
I can't think of any can you Mark? ? ?

So now we have both of the airboxes that you claim to be factually inferior since '01
outperforming all bikes with a thorsten style boxes for one reason or another.
*I don't claim that Damon or Chuck's results come from their moriwaki airboxs, but it proves you wrong and thats what matters.

Now as far as a real world/OEM unmodified motor comparison between the thorsten and moriwaki airboxes,
I don't think this has ever been done and if it has the results haven't been posted for everyone to see.
After I get my bike back together it will be going back for another new custom map which I will then use to compare to my last map graph results w/ the thorsten box.

Then we will have some useful data to compare their performance results, not just you shooting your mouth off. :rockon

Regardless of performance gains, I'm pretty sure the Mori (& HRC?) airbox has one advantage over the Thorsten/TurnOne design. You can use a kevlar fuel cell instead of the stock tank.

hard to dyno a airbox insurance claim

the mori box has not outperformed a open style unless on a worked on motor, please show me the graph tunna

there were people running the mori box years b4 you ever had a 51 and most of the people running them long ago gave up and moved on from their 51's.

have at it you clearly have a dog in this fight and i am sorry what i said does not go with your scheme:notworthy

YOURE the reTARD who is claiming that one box outperforms the other! ! !
So don't ask me for graph's of anything, just shut up and admit you didn't know what you were talking about and you have no proof to back it up.

I already addressed each of your points in my last post. But since your too BUTT-headed to take the time to read and understand, Ill post it again for you so you CANT MISS IT! :banghead

If you are such a GURU, what year did I get my first RC51 Mark?
I want to be sure of how many "years" all these "people" had been running these boxes before I ever got my RC.

Scheme? Fight? Dog? WTF are you babbling about? Actually, I could care less, please don't tell me. I'd rather not even know.

for anyone with the moriwaki airbox or squidskinz airbox did you in fact have to remove the thermostat or is there a way around that? any other mods that would have to be made in order to install one of these?

RC51Stunna

· #17 · Nov 4, 2010

I have the moriwaki airbox and it came with a thermostat replacement tube, but I have learned that their was some kind of shortage of these parts to the number of airboxes that they made so you can not get one from them any longer even if you buy one of their few remaining new airboxes.

I have also used a turn one thorsten style airbox that did not require a thermostat replacement, but you did have to turn it around or upside down or something to get it to fit under there.

Im not sure how running the OEM radiators would work without the thermostat but I know that with front mounts you will want to have one of these thermostat replacement tubes in place for best results and most weight savings. If you need one, my friend Nick in AU is making them by order for around $100 shipped.

ok the little i know about this is i have a QB carbon airbox which is a copy of the HRC box and you do either have to modify the standard tank or run a carbon tank due to the size of the box it has no deflecters inside.
mine came with a thermostat replacement pipe but i think you will find any full race engine doesnt use a thermomstat due to it restricts the water flow to much.
as far as the moriwaki pressurised box is concerned mori did lots of testing untill they found a size that worked in all rev ranges.
the big problem with the turn one type is in racing its needing the tank to make the seal hard cornering braking etc causing frame flex caused the frame to part with the tank and you would loose your airbox pressure then loose power and thats not a good idea.
if this design was good dont you think honda and moriwaki could have saved thousands on only making the base to an airbox rather than a complete box.

Cool stuff Rick, Id love to see some pics of it if you have any. I wonder if the QB carbon tank that they sell/sold was made to fit this HRC replica airbox?

I believe they sold a road and a race airbox if I recall correctly.
Maybe the difference between the two was the race was the HRC replica *the one your have and the street was the Moriwaki replica that fits with the OEM tank.

Great point about all the testing they did and the extra secure ram air seal you get from the HRC/mori design. I am hoping that it will also produce more power than the thorsten style airbox due to all the testing work that they did.

I was told no thermostat removal is required with SquidSkins airbox. However it does require thermostat removal.
The main reason I ordered the airbox was because the ETI fuel cell contours do not match an unmodified Turn-One airbox (much to my disappointment).
