more midrange with 2, more top end with 4? that would be my geuss
sideshow said:straight from Yamaha - GYTR VStack kit:
For improved power across the power band ( ideal for road racing):
* move the two stock outside stacks to the inside (cylinders 2 and 3) and then use two stacks from the kit on the outside (cylinders 1 and 4)
For maximum horsepower on top (ideal for drag racing):
* use all four stacks from the kit - gains of 5 hp on top can be achieved with proper tuning (no remapping is required)
very true. im goin w all four. yamaha has a high rpm for a reason, we must utilize it in order to enjoy the true essence of what our r6's offer.CephasGT said:Just use all 4. You'll still gain mid-range power, just not as much as with 2, but almost as much, and you'll get more top end. Seriously, who likes to dither around 7000 RPM anyway? 10k+ is where the fun's at.
With just VStacks on a stock bike (I think that's what you're asking) the gains won't be all that much. Intake mods feed off of each other, meaning you're not going to get what you could off of one without doing the rest. But you'll definitely pick up at least a couple horses.epiphone3 said:do you gain pretty good even without a remap? I know it won't be as good as with a custom map, but lets say you only have the stacks as a mod...

Is that your only mod, jinx??jinx1812 said:I installed some onto my 01 over the weekend. I debated whether or not to install 2 or 4 as well. I said the hell with it and put all 4 in. I've noticed no loss of power on the low end at all and my bike pulls a lot smoother and stronger then it did before. I haven't had the chance to really put it through the paces at higher rpms, but like I said it was silky smooth throughout the low and midrange. I may be a little crazy but I swear my bike sounds a little different now, too. As my wife said "it sounds more growly" lol.
I think that you should go ahead and get a PCIII, and be done with it. If you can't... I honestly can't say how the bike will react, since I did a PCIII before all my other mods.epiphone3 said:I think I am going to go for the superflare stacks for my 2005. I think I will also go for the +4 ignition advance rotor. I think I will be happy with those and they will allow me to mod without having to get a PCIII.
What do you all think of that? I should end up liking that. Do you guess think that Velocity Stacks and/or the +4 ignition advance will help my on/off throttle abruptness??
By the way, does anybody here know of an octane booster that works with our bikes? I am just looking for something that comes in a bottle that I can buy at Autovalue or a gas station or something. Reason I am asking is that it is possible I will ride places that do not have Premium gas in the future and I guess that with an ignition advancer I would need to run regular gas plus an octane booster.

As for the octane booster, I wouldn't bother with it. Lots of people on the board have run 87 in their bikes with no problems, so if you get in a situation where premium isn't available, don't worry about it. I've run 89 in my bike several times and not had any issues with it.
