pipes: Stage IV, propipe, bigshots, rineharts or muzzy
air: PR BAK
& Power Commander PCIII USB

Will put the bike around 90 rwhps up from some 72-75ish. A huge gain if you think about it.

The VBAK is a big air kit made by one of the members (Churchkey) here. It uses aluminum bent pipes, K&N filters and rubber clamps to mount it onto the engine.
The PR BAK is from Patrick Racing and uses machined billet venturi stacks on top the throttle bodies paired with oversized mounting K&N filters.

Both setups are a big win over stock. I have the PR setup in my bikes.

I am in total agreement with Oliver, minus the BigShots....and I prefer Churchkey's VBAK over PR's AirKit.....

I really don't think a set of pipes can look any better nor sound any better than the Rinehart's, but than that is my personal opinion.....I have had the Propipe and by far is the tops for power and from what Oliver said the Speedstar pipes are right there in comparision in the power bracket.....

My guess is 84HP on a good day.

The speedstar kit should get you closer to 95-100 HP


This what I don't understand and I have read quite a bit on this:
If you look at the number of the 108 and 110 kits and then look at the numbers of the speedstar kits there is really not that much differance. In some cases the 108 and 110 kits have lower HP/TQ numbers. Take for instances my last bike had a dyno sheet of 103HP and 122 TQ 2002 speedstar kit with sidburner pipe. bike Iam bidding on has 108 kit and 94hp 122 Tq. They both have upgraded pistons and cams and air kit and good pipes.. I understand that every dyno is going to be different on any given day but you would think the Big bore kit would produce alot more..

I have Churchkeys V-bak, Propipe, AIS removal, Powercommander PCIII and custom map on dyno. Results 89hp and 112lb/ft. Did not dyno before mods but the difference is noticeable.

Wrong Air Kit at the time but this from 2004, Hope it helps. I cut it from my past post:


Ok, so let me start with it has been 12 months since my last trip to the DYNO. I had a custom map done. At that time I had HK Kickers w/stock baffles, Thunder BAK and a PC3. It was a hot summer day and it ran 79 HP and 108.5 ft lbs of torque. Not bad for the HK's which basically eat power not make it. In the past year alot has changed or maybe not. The recall (Motor torn apart, new rings, nothing else done), a 31 tooth front pulley, the 240 kit, the oil cooler and Mobil 1 synthetic (more stable oil temps), then off with 240 and on with the 280. So is that a little or a lot??? Well I went to the "Spirit of America" Bike rally in Worcester, MA. I went to RDS (Rob's DYNO Service) a mobil DYNO guy that Race tunes for lots of New England race teams. He is Dynojet certified, and runs the latest everything from them. He is also a S&S certified tuner, a Kawasaki certified 2 and 4 stroke tuner and Electrical and FI specialist, a Certified Victory Master service tech and a Boyesen dealer and tech. He is currently designing a performance engine for Victory. Short- He knows his way around a bike. I have talked to this guy several times and finally got the bike to him tonite for a baseline run. I need a new map, I have some stumbles after the recall. I also have a V-BAK pro from Churchkey sitting in the garage and wanted to know what I actually get out of it. I also wanted to know how much power the 280 is eating up. So if last year was 79/108.5 what would it be.

Todays conditions at the DYNO 84.69 degrees, 29.60 in-HG, SAE: 1.02

That means something to somebody here I'm sure, SAE Smoothing: 5

Six runs, best being 71.39 HP and 97.79 ft lbs. The HP peaks at 4600 RPM, The torque is Peaked and pretty much flat from 2700 all the way through 3700 RPM. That is a loss of 7.61 HP -10%, The tourque loses 10.71 ft lbs -10%

It was figured that the 31 tooth front pulley gives a feel of 3% more power. Then it was figured that the 240/280 would give the effect of a 6% power loss based on overall gearing loss. That left a net loss of 3% So I guess the rest can be attributed to the extra unsprung weight and the extra drag of running a tire that is three inches wider.

My A/F ratio that was perfect last year is a frickin mess, 16 at 2000,10 at 2500, 13 at 3500 and 12 at 4500. I need a new map... after the air kit goes on. This is caused by what I am not sure. The only real change to the motor was the recall. I had mentioned the my numbers were low as with most others running 2 into 2 pipes, free breathing power eating pipes. He suggested Big City Thunder power chambers, the Power Monster series. With these he says he been able to achieve a 12 HP gain over Open pipes on another customers bike after a custom map. After a quick phone call to NC they don't make them in a 2.5 inch version. But offered to make me a set if I didn't mind waiting for them, WooHoo. We'll see what they do... I plan on mapping after the Air Kit and then again sfter the Tourque Chambers go on.

A few notes from today, HK Kickers are seriously loud even with the baffles in. I and a bunch of "Watchers" had on ear protection during the runs. Eight of them. Those without them grabbed their ears and scattered at about 4000 RPM same thing each run. This thing sounds sweet while she is screaming... Also I feel great, the bike was outside the DYNO stand for about an hour after the runs. We were between Big Dog and Titan. People walked by them and then stopped to take pictures of my bike, how cool is that. About every third person that walked by stopped circled and took pictures. I smiled all the way home. Nobody knows what it is, but everybody thinks it is cool.

This was from May of 2005 after some upgrades...

Yes getting a custom map makes all the difference in the world, read on... On my first trip tp the DYNO I had only the Thunder BAK and HK Kickers and a new PC3, I got 79HP and 108.5 ft lbs. that was with the stock wheel. After the recall and the upgrade to the 280 and 31 tooth front pulley. I went back and scraped a measly 71.39HP and 97.79 ft lbs. rather disgusted with that one. The tire ate a good chunk of power but the motor had also been apart for the recall between runs 1 and 2.

Over the winter I did or installed these pieces:
AIS block
PCV valve
Churchkey VBAK
PR cams
PR 10.25 pistons
PR Titanium rods
PR HD Valve springs
PR Ceramic face lifters
Yamaha S* ECU
V&H Propipe

I gave the motor 400 miles for a break in. I went back to the same guy for my new Custom map. I now use 92 octane gas, it was 73 degrees today, the air pressure was 28.83 and the SAE correction was 1.03, I have no idea what the altitude was where we were.

She clicked off a whopping 79.49HP and 104.63 ft lbs. I had an increase from before but was hoping for much more... The bike showed good power up to 3500 RPM and then just dropped off(the green lines), the A/F was way out of whack from there up. The ratio hit as high as 17.8, the bike was looking for 61% more fuel than it was getting. He started the mapping process, an hour and a half or so later we had it pretty well nailed. I'm happy!!! The final result was 93.15HP and 109.79 ft lbs., yes getting a map makes a whopping difference. The bike runs much smoother now and my decel popping is all but gone... Peak power hits right about 5000 and the torque curve is over 100 from 2700 all the way to 4800 with the peak around 4000. The A/F line is just about as flat as it's gonna get. So all in all if you figure in the loss for the 280 the new HP cost about $100 each.

Just to set the record straight:

V-BAK velocity stacks are 304 stainless steel.

There are rubber connector sleeves to attach the stacks to the throttle bodies which are held in place with stainless steel clamps. It is my opinion that a mechanical means of attachment is superior to other methods. The mechanical attachment also allows the user to easily remove & reinstall the air kit.

And I might add.....cost you a whole lot less than the other kit....[/emoticons/emotion-2.gif]plus it looks Bad Ass with those Stainless Stacks!

It's also where these kits make thier HP and torque. At 1900 rpms, I'm already making 100 ft.lbs. and never does fall below that 100ft.lbs till redline. So all in all, it's also how fast the bike will make the power. You'll see mike when you win that bad boy.[/emoticons/emotion-5.gif]

The more I read............ the more confused I get.
Thank you DNGrumpy for the update.
Still you are saying that the Yamaha Stage IV is better
or equivalent to the 110 kit?
I do understand the need of a good custom map, in order
to extract the best from the engine. But I would like to
read some feedback on Stage IV vs. 110 kit.
Thank you.

Last summer I switched from 93 octane to the cam 2 racing fuel.My pipe was always black on the inside and the bike would still ping at lower speeds .After switching to the cam2 fuel the pipe is gray inside and the bike runs like a million bucks.So when you guys are running your dyno runs you should also note what fuel you are using.
