rineharts lost 8 Horse Power

[hoehandle]

I started with an 02 and the SE1 flash, factory "V-Mod" pipes, topless and a
28 tooth pulley. Had a dyno run this past spring of 111.7 RWHP. Put on the
rinehart pipes and a "dyno tuned" Power Commander yesterday and was
left with 103.9 RWHP. Just to be sure of the 111.7 RWHP I had a
baseline dyno run before the pipes and PC were installed, and it was 111.5.
I expected a gain of 5 HP and lost 8!
The only benefit is that I'm not burning the calf any longer.
Where did I go wrong? Any suggestions?
Thanks,
Brian

In all honesty I seen a lot of builds loose hp with Rineharts. They are selling a name not horsepower. I see this on the dyno and hear of it from other tuners that Rinehearts stink. So get rid of the name and get something that works. As far as the Powercommander goes, if it wasn't dialed in it could hurt you but no 8 hp....its the pipes.

You sound like you know what your talking about . From what you,ve seen , what pipes really work . I got the Wild Pigs but don,t like the way they sound . Seem to perform good though , but never went on a dyno . Thanks

Again, to be Honest with you I haven't got the experience with the V-Rod yet, although I am starting to play with one now. I want to try the S/E 16 Guage Double Barrel pipes....I heard good things about them.
As far as the Rienhearts go they are failing on most bikes out there.
Sorry I couldn't help you more with the V-Rod....I won't tell you lies, If I haven't tested them my self I won't give you an opinion. Sorry

Ooopps . My fault . I didn,t realize we were talking about the V-Rod . I got a 2000 FLHT . I seen something about reinharts and clicked on to it . Sorry !

In that case I can say a little in that area!! There is a lot of threads on this site that cover exhaust systems that work so you need to search them out to begin with. I found that my customers that don't have a big build but don't like the S/E Slip-ons because they are too quite, love the Samson Rolled Ovels. They perform very nice and have a Great Throaty Sound to them. The are a little louder than S/E pipes and they perform a little better than the S/E pipe. Now thats a good slip-on and it will flow good up to 100 hp/ 100 tq. Dyno Tested!!!

Am I the only stupid SOB in this chat room with the power loss from the Rineharts? Does anybody have an idea of where the problem could be?
Thanks

Maybe you are the only one who will admit you got a power loss from Reinhearts.....they are spendy pipes so people don't want to admit they made a mistake. Now it sounds like you don't believe the pipes lost you hp. If you had the hp before you changed the pipes but don't have it now it has to be the pipes......wouldn't you say!!

i dyno'd mine stock at 105hp & then installed the rinehart pipes, k & n airfilter, removed lid, changed the long velocity stack for a short one, & got the power commander with the correct map downloaded off their website. the bike dyno'd at the same peak of 105 hp, & gained 13 hp between 4,000 & 7,000 rpm!

I wonder if all the things you added had anything to do with a 13 hp gain. I put a S/E airfilter, S/E slip-ons, and a Dynoket kit and gained 10 hp on a stock bike. My point is there are better pipes out there and I am SURE that if you used something else other than Reinhearts you COULD have gained even MORE than 13 hp.

Please remember I'm old school so my opinions may be out of date, but I have a friend who has Rineharts on his Road King and I couldn't help but notice that the total length of the pipes for each cylinder are not equal. I would think that this would have an adverse affect on the bikes performance, as one side would flow better than the other, creating and unbalanced exhaust, 'pulsing'. As a former drag racer, equal length pipes were always considered mandatory. Just my $.02....

Good point Mad Dog....there are some true duals out ther that do a good job and even though the rear pipe is a little shorter it has sharper turns which slows the effect of inertia and pulse scavanging. Its the collector where Rienhearts fall short. Again this is not my opinion.....it's Dyno proven, Reinhearts are not on the top ten list.
Now with my $.02 and your $.02 Mad Dog.....adds up to about what Rienhearts are worth. Although I would run Rienhearts before I would run 2 1/2 inch short drag pipes on the street!

Mad Dog,
Yeah, that used to be the general rule. But we've found that it's not EQUAL length anymore, it's CORRECT length. And with separate timing, heat, fuel reversion from front to back cylinder, and other issues like time it takes for exhaust wave to reach the baffle, especially EFI bikes, that EQUAL doesn't quite make it sometimes. Trust me, I'm old school, too, but didn't do as much drag racing as you where really EQUAL length probably worked well enought at WOT 95% of the time. Manufacturers have simply gone too far for the sound and looks dept. Very few are doing the intense testing required to get the best perfromance, too. They want to sell pipes and unfortunately, like most things these days, it's form over function. Something us old schoolers don't usually understand. I say make it work right first, looks comes later.

[andy b]

like i said before, i didn't lose any peak & gained 13hp in the middle. maybe not the best performing pipe, but just my opinion, the best looking pipe. i never cared for the factory wrap around style. it just looked too big & bulky. the rinehart's look lean & mean. actually make the bike look lighter.

[Mad Dog]

As it is important to some, (not me), I have to admit they really do look and 'sound' great! Many do not like the Thunderheaders I run. They say they're too loud. But that's only because they're always behind me when I'm at WOT!!!!
