one other note for all you haters / Go to the master Gary's site and look at the torque dyno for the WB with stock airbox and 155 main around the 4-5 rpm range now right it down. Next go to the HMF site and look at torque dyno with stock air box and 155 main right it down and compare. That should back up my statement that the torque for the stock air box is impressive with the HMF. Heck compare it to the torque of Gary's kit. I rest my case.

 

Just correcting your mis information, I never get excited. But Gary don't push any pipe, if he was going to build his kit for certain pipe, It would have been FMF, not White Bros. And you should know you can't compare one dyno to a different one. If your happy with that pipe then don't worry about us Superbike shop guy's. Sure if you can't tune your Predator then you are probly better off with a 155 main and HMF pipe. Is it going to be faster than another pipe on a properly tuned machine, NOPE !!!!! Has nothing to do with the airbox. Like I said before, all pipes tested so far properly tuned, there is no stand out. There basically the same. So you have no case. Sounds like your the only person getting excited, and why are Superbike people haters, just because we test every part and make sure the claims are true before we use them. Like i said, name brand means nothing to me, just performance, if it makes better power than I have now, I will use it.

 

It has everything to do with the stock air box. The WB does not have great low-end with stock air box look at Gary's dyno it speaks for itself. You start your arguments about dynoing different pipes and then when someone brings up the facts you start talking out of your *** . The HMF low-end is good with the stock air box. Dont jump on me about tuning your the one that spent 100 bucks for some unknown jet size because you were promised the world I can jet just fine. I dont need to do anything with the needle because I am leaving the stock air design. If I decide to change it I will go buy my own jets and jet accordingly so you should think before you speak. And since you test all the products tell me what you dont like about the HMF. You should compare apples to apples, stock air box against stock air box not a totally reconfiqured one.

It is plain and simple Gary designed his kit using the WB slip on. I called and talked to Gary and was quizing him about the pipe set-up. He told me that with his air box mods the WB works best with his end piece configurations. I am sure he could get just the same results with the HMF if he took time to fiqure out the jetting and other configurations. How many FMF pipes have you tested because I just called last week for info before buying a pipe and they did not even have the design for the mid pipe done yet. They told me 2-3 more weeks. So I dont understand how Gary is testing all these pipe, The only two that have been out for a while is the WB and HMF. Yoshimura is just releasing theirs, trinity is starting to sell, big gun is out, MBRP is out, Aaen is out and that is about it as far as I know. How many of these have you and Gary dynoed. You see I called all of these and got the dyno #'s before I purchased so I am not just someone who went out with no thought and purchased a product.If he can show me a dyno stock air box against stock air box with the WB on top for low end torque that is just fine but I dont think it is going to happen from the feel of riding both and comparing dyno #'s. How many how you rode with the HMF? So many people speak HP but torque is what will get you to the top of the hill without stalling.


here is the info I gathered.

HMF - 5 hp gain in the middle 2-3 on top / 5 ftlbs of torque increase at 5000rpm
WB - HP curve is pretty much identical but lacks low end torque of the HMF
FMF- had no info available ( should have called gary)
Aaen - 7 hp increase could not get torque info ( no spark arrestor available is why I did not go with them )
Big Gun - could not get dyno info ( should have called gary)
Hot seat - ( told me to call back in a couple of weeks)
MBRP - 1.5 hp increase with slip on thu out entire range ( not impressive) they did say that they could get
better #'s if I buy the whole system. no thanks
Yoshimura - gained about 3-4hp in the middle with about 1-2 on top - torque was right at about 3-4 @ 5000rpm

That is all the info I could get last 2 weeks before I bought.

 

I told myself I was gonna stay out of this argument, but I just couldn't stand seeing blueblaster get the punches thrown at him!! Sp700, I realize you are very satisfied with superbike shop....this is obvious as you never stop talking them up. But Give 99BB some credit here, as he has stated that he talked directly to Gary, and has done other homework as well, so I don't think it's fair for you to say he's a lazy mechanic because all he has to do is change the main jet 1 size. If it's what the manufacturer reccomends, that's all there is to it!! Polaris recommends no jetting change according to factory spec, and yes, as we know, more gains can be obtained through airbox modification. But 99bb is correct in stating that through his reasearch, that all angles kept stock except for the silencer, the HMF is going to outpull. Now if you spend the extra $100 for the airforce kit, I'm sure the W/B will produce similar numbers...bigger according to Rath?...NO!!! But I have to agree with 99bb, in that for the $$, the HMF will give you great numbers while keeping the airbox stock, which is very beneficial for those of us that have never seen sand dunes...they don't exist in Iowa!!! You are entitled to your opinions in this forum, but please keep from lashing out directly at those that have given us a very fair comparison as 99blueblaster has done with the WB vs HMF according to manufacturers specs...no other mods affecting results!!

 

First of all, unless you use the same dyno, all these number's are useless. I hope you don't believe all the advertised dyno numbers. Your MBRP numbers are wrong, most all of the numbers you posted are wrong. FMF made basically the same number's as the White Bros, and the slip on was a little lighter, but not worth changing for. Superbike didn't build the White Bros pipe, So they don't care what pipe me or any body else uses, they do let us know what works and what don't. So if you want to talk facts, get some first, advertisments don't mean crap to me. If HMF works for you, be happy with it. The Airforce kit will work with any pipe, actually it will make any pipe alot better. White Bros. just gives the ability to fine tune the exhaust to your engine set-up. My point was that Superbike does not promote White Bros just because of the airforce kit, The kit will work with anything, they use this pipe because nothing else tested has shown to be worth the money to change. (so far). And using Pure Polaris parts supports Polaris, the company that brought us the Predator to start with.

 

Have you guys missed the point here?? Gary is a HMF dealer - why wouldnt he use HMF instead of W/B if he could get even close to the same results? And you only need to spend about 6 bucks to bring the W/B to life on univents or you can run a slip on ru1770 and when properly jetted (AND YES THIS IS THE KEY ISSUE AND WHY YOUR FRIENDS W/B IS UNDERPERFORMING) you will spank any pipe out there. But talk is cheap and soon you will learn by experience the W/B is a far better pipe as it blows in your face as you try to keep up with your HMF...

Pudljumpr, No one had to even bring up the Superbike shop in this thread, everyone that uses another vendor alway's looking to take a cheap shot. Advertisement don't qualify for accurate information. If you bolted on everything people advertised and you got the HP they said you would, everybody would have a 100 HP quad. My Point was as stated earlier, Superbike recommends what works best, if that change's they will be the first to tell us. They are not promoting anything just because of another product. Hey run what you like, don't matter to me. So far there all producing the same number's.

 

Your right, not all dyno's are the same, but when I shop for hp, I don't look at who advertises the "biggest numbers"!! Look at these companies, they show a curve for a stock pred, and a curve for a piped pred. I agree, the numbers that some dynos read for the stock machine do vary a bit. But look at the difference bet. the two. That is what 99bb was stating. Gains is what is key, not top hp! I don't know why you gravel before superbike shop so much, but just try to keep an open mind when others offer good information. I think I'll quit responding to this thread, casue as I've seen in other threads, people can type till they carpultunnel in their wrists, but you are still not going to stop and ponder the resultes, you will just retort with "Gary is always right and knowone else knows what they are doing". Just stop and smell the morning coffee for a few minutes and see what is wrong with that mentallity when offering advice!

 

And knowone came in to discredit anyone...99bb just stated that he had talked with him...that is when you loyalists become defensive, even when negative comments were not made!

 

Don't make the false accusation that someone is trying to Fab #'s. See your jumping in and have not even read all the post. Gary sells every brand of pipe, so he has no reason to fab anything. Stick to true fact's, and no one will say a word. Like I said there all the same, I don't give a rat's a?? what you use.
