950 performance question
Hello all. Just bought an 09 v star 950. Very happy with it. The previous owner put V&H 2 in 2 and V&H FuelPak on the bike. Other than that it is completely stock. I know stock numbers for the bike are around 45hp and 50tq. My question is with these add ons, how much, if any, these numbers jump. Not looking to go fast, I am a novice rider, just curious about my new bike. Thanks so much!

RE: 950 performance question
I have to assume that you mean Vance and Hinds two exhausts into two pipes instead of the two into one from the factory. Not sure with a fuel injected system what the FuelPak is. Maybe they have changed the fuel mapping for the V&H pipes. With most of these types of upgrades, exact numbers for changes in performance are not given because all bikes are not created equal. Some do better than others. If there is an advertised improvement number, the vendor could be held to it. Just saying. Oh yeah, congrats on the 950, I just got one myself,

Yep that is the correct set of pipes. And thank you. I just didn't know if there was a generally accepted number just as a ballpark as to what the added numbers were, like is it closer to 2 or 15.... I just have no idea. I believe the FuelPak is a FMS made by V&H to go with their pipes, tho it seems you can send a request for the codes to them if you have a different exhaust.

When I got the bike and saw it had V&H pipes, I started looking up other 950s with the same setup, and some had a FMS and performance air filter installed. I read up on it a bit, found out the bike had a FMS as well and just started getting curious. Is an upgraded air filter something that I should be looking into, just so the bike runs ok with the better exhaust etc? Congrats on your 950 too, btw. And thanks for answering.

RE: 950 performance question
The acronyms have me confused. FMS = Flash Memory SIP ? Fuel Management System? It must be changing the fuel mapping in some way. There is a good chance a different air filter would add to the overall performance. I don't now.

I took my bike up to see my son where he works the other day and he looked it over and said, "You know if you change out the pipes and the air filter you'll get better low and mid range torque". My response was, "Great, but, I already have enough of both of those". Then he started picking at the end of the accent trim on the side of the gas tank and said, "I'd take those off if it was my bike. They're only on with double-sided tape". At that point I threatened to cripple him up if he touched anything else. Shy I'm one of those guys that believes that, " If it ain't broke, don't fix it". Shucks, It's a brand new bike. Let me at least break it in.

Welcome and congrats on your choice of ride, also to @commonground. To answer one of your questions.

In a word yes! You have a big and more free flowing exhaust system, to help it reach its optimum operation and to also help the motor attain better performance you should fit up a better air filter. Something along the lines of a Big Air Kit there are heaps available, Barons being just one Google them.

Having the motor breath in and exhaust better will help with your power and also economy, not to mention it will sound way better too!

RE: 950 performance question
it's not so much about the numbers, because if you actually knew them you would very disappointed at how much just 1 HP cost you in dollars spent. what improving the breathing of the motor is about both intake and exhaust is improving the torque curve making it higher for longer (without dips) giving you much more usable power, that is to say more power over a wider rev range. this will give you a feeling of speed more often. those numbers they quote for maximum HP are next to useless if they occur at a very specific rev range and 100rpm either side of that it drops to 3/5 of , well much less.

FYI I would estimate that you would be very, very lucky if you were to achieve 4 extra HP with a BAK, and free flowing exhaust properly tuned. sounds disappointing doesn't it, but think about it, that's huge nearly 10%, but you wouldn't know where to find it in the rev range. so that's why the torque curve rather than peak HP
you could of course get the bike Dynoed and have it tuned for the best possible performance all round, but don't sweat it it not about how fast you get there, but about how cool you look on the way.

RE: 950 performance question
i've seen other 950 owners quote dyno numbers of around 12HP increase with aftermarket exhaust/fuel processor/air kit. the others are correct in that you should get an after market air kit to fully realize the performance gains of the trifecta. for more power from your engine, you need more air and more fuel. you've got more fuel coming with the fuel processor, but now you need more air and you can only get that with an air kit. with just your exhaust/processor, i would guess you have about 6HP or 8HP increase over stock.

RE: 950 performance question
I have 09 v star 950 and I just bought the Vance & Hines Big Radius exhuast system. I 'm considering the Vance & FuelPak. Has anyone had any experience with it, or what aftermarket fuel management, ignition managment system works best? Thanks for response!
