No, not the GSR. Just a mid-90's
Intregra LS. After a few minutes of traffic tag we came up to a three-lane red-light. I was anxious to see how the new pulley would perform, so I wasn't gunna be picky about an opponent. This white Integra seemed perfect for the test<img src=/images/forums/snitz/smile.gif width=15 height=15 border=0> I was in the right lane, he was in the left,the middle being taken up by an Explorer. I reved up to 2500 rpms and slipped the clutch
fairly slowly. By the time I cleared the Explorers bumper enough to see the Teg was a half car length ahead.
I watched till the rpm needle was around 6250 and shifted...pretty good shift too. I glanced as I completed the shift to 2nd and was a car length ahead. I did nothing but pull from that point on, better than I every would before the pulley. He shut it down around 80 or so, several car lengths behind. At the next light he just pulled up along side and looked over at me...like curious or something. I just looked back waved and grinned. Yeah, that pulley makes a difference. I don't think Shawn's statement about 6-10
hp at the wheels for a Tib or Elantra is an exaggeration at all....I just hope the whole "harmonic dampener" issue doesn't crop up with this mod.<img src=/images/forums/snitz/uhh.gif width=15 height=15 border=0>

nice race maxx.....my first race with my elantra was with an old LS.....i blew its doors off as well....now i dont wanna flame or even remotely sound like im flaming, but i dont know about the 6-10Hp on the pulley thing.....i doubt that a pulley would make anywhere near 10 hp maybe more like 3 or 4....but hey i could be wrong....you should dyno the car and get some real answers...im just saying it because i thought that my TB would make like 15 HP and it turns out that it really makes like 5 or 6...lol oh well....excellent job with that teggy....keep on building your car....you'll get respect. trust me. <img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0><img src=/images/forums/snitz/approve.gif width=15 height=15 border=0><img src=/images/forums/snitz/cool.gif width=15 height=15 border=0>

Thanks Snuckles,
Yeah, I had a lot of questions about this mod...including the hp gains.
Shawn, at Unorthodox Racing,told me that they have already dynoed our cars and gotten between 6-10 hp...depending on the car and the dyno. I would like to see a dyno on my car of course, but the difference in the performance was obvious as soon as I pulled out of the shop. I don't know if I would have even noticed a gain of one or two hp.
Whatever the gain, the car is obviously faster. <img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0>

Two things:

#1- 10whp on a 2-liter 4cyl from just a pulley.. I know you don't buy that!

#2- Guys have had MASSIVE crank failure on their Honda's thanks to the lovley engineers at UR and their Harmonic Dampnre-less crank pulley's. I'd think STRONGLY of removing the pulley if I were you, my motor isn't worth blowing over 4whp, but that's just me. UR's newest set only now incorporated the dampner after UR realized they were killing cranks left and right. I'd either look into getting one with the dampner or going back to stock dude, just some friendly advice.

VTC,
I appreciate the imput, it is a concern that I have been investigating, but to be really helpful you're going to have to be more specific. The range U.R gives is 6-10 not...10. Shawn at U.R told me he felt some dyno numbers seemed over-inflated...but that was the range they got. Also, I can't tell
much about these guys who had the problem. Are you talking about two or three peeps you heard about..or several that you personally know?
What other mods did they have on the cars. What year and style of Civic?
All these things are important for anyone to know before making any decisions. In fairness to U.R, I'll
ask them personally about this subject. Thanks.<img src=/images/forums/snitz/wink.gif width=15 height=15 border=0>

U.R.'s reply to VTC comments:
The statement about making pulleys with dampeners was "news to them".
They are making dampeners for race imports that are producing 5-6 time stock HP...based on V-8 engine dampeners introduced this year. Shawn also mentioned that their customers have logged over 600 million street miles with their pulleys...over the last 4 years.
I asked Shawn if he could provide us any data on the frequency of crank failure or damage in U.R. customer's cars as known to Unorthdox Racing.
I'll post that info if I receive it.

Well I don't know what "Shawn" at UR is telling you or from what source he speaks, but the underdrive pulley from UR has made it's way into MANY Honda's over the past 4 years. In doing so, crank failures have noticably increased in time with cars equipped with UR underdrive cranks. The gist of the problem seemed to be with B-series Honda engines which makes sense since these constitue about 75% of modded Honda powerplants on streets. Naturally these problems don't surface in hours, days or even months. The slow but detremental effects of the unbalanced vibrations traveling though the crankshaft takes it toll unill the damage is unrepairable and fatal to the crank/bearings themselves. So in reality, yes Shawn can say they've logged a billion miles with no problems and be absolutley correct, but what he fails to lead to is that fact that it is with time that these issues develop and become problems. And it's within a year or so that it seems the problem has reached the point to where nearly everbody has heard of a case of crank failure on a UR pulley equipped engine. These aren't simply "made up" from thin air, though not everybody may be able to pinpoint a case, all these rumors have stemmed from occurances of the actual problem. BTW I do know of at least 3 people I've spoken to who've had or had a friend experience crank damage/failure on a UR equipped motor. The choice is yours to be quite honest, take "Shaw's" word or mine, that's your call and I leave it to you.
