I have a 99,with a slip on Quill high mount.. It makes good power,but I am looking for more.. I do have an Attack Ram Air.. anyone tried the Akro and an Ivans Kit with the ram air ? Ivans site says he designs them for stock airbox.. Also,any oppinions on a higher horsepower pipe ? Thanks.. Brian

What doesnt kill me.... hurts real bad

consensus says Akra is the best performing pipe although you will pay for it $$$

I would call Ivan, you might really hurt performance with that much extra air. Maybe a tuning shop can help but there's no way they are going to help simulate ramair at 120mph.

Akrapovic is definitly the best pipe for most rwhp. BUT witht he ivan jet kit watch out. You are not even supposed to use a K&N air filter with it. The jets are the best with the akrapovic system but you will LOOSE SOO much low end if you put an airbox on it. I would use different jets like dynojet jet kits for it. YOu won't loose as much down low. If you really finely tune your carbs and i mean finely tune them you will gain some serious hp but it won't be easy

Learn how to get it up!

If it gains power way up high and loses low, it really isn't losing it low it actually just moves the torque up farther in the curve. It may take an extra 1k rpms to build the torque than before the mod. You can fix that with a timing advance kit. It's like degreeing a cam on a truck. When you use a horsepower (mid to high range) on a truck you push everything up in the curve which will hurt you if you tow with it. You can degree the cam and bring everything lower in the curve so that the torque will com in sooner and the midrange will start to push sooner. But, I agree with your suggestion to use a kit that will most likely not have this problem because he will have one of two problems. Without the advance kit he will lose throttle response off the line and the power will come on like a freight train in the mid-range which kind of kills you in any situation where you want/need straight line acceleration or with the advance kit the freight train is moved down in the curve and the throttle response is greatly improved but the power will peak sooner in the curve. It really all depends on what you want the bike to do. Do you like that top speed or do you like the bike to pull hard down low. Most of us don't ride our bikes at 170mph everywhere we go anyway, but owning R1's I'm sure most of us can agree that the chassis doesn't need alot more low end, which the advance kit will do, because it may wheelie uncontrollably if you try to holeshot it.

Like i said you loose low end. If you have ivans jets then you know already that your bike is ten times harder to launch off the line and many people actually get worse times racing with ivans jet because it is so hard to launch. My bike had nothing down low. It was doggy and had no power. Just my two cents. Mid and higher revs sure it helps. i picked up third gear wheelies like no other. but racing and launching is another story.

Yep, that's what I was saying too. Launching and R1 at any kinda revs is like trying to jump onto a moving train when you don't have alot of A$$ to hold it down and mine isn't even modded yet, other than exhaust. But, yours being modded must be more like trying to jump <font color=blue>IN FRONT</font color=blue> of a moving train/images/icons/laugh.gif!



If you want to know how good the tail section of an R1 looks...Just ask a Honda rider!/images/icons/cool.gif

I looked here and there for info in various tuning kits, and the word I got back invariably is that Ram-airbox additions to non-ram-air bikes is a *bad* idea. They're an incredible pain to jet properly as most tuners don't have anything like a windtunnel to generate those kinds of air intake. (I was seriously laughed at when I mentioned air compressors... apparently these bikes will gulp insane amount of air in the powerband)

Most reviews and tuners I've talked to recommenend the full akrapovic normal mount system with Ivan's jetkit for the best topend gain, but it usually kills any power below 4k. Just the Ivan's jetkit with my stock bike increased the powercurve in every spot except under 3k (useless anyway) and all the way to just short of peak (I actually lost 2hp at the top, but gained alot in the midrange). I'm assuming I gained that back with the akrapovic slipon, but I've yet to test it.
