I'm guessing the Unorthodox Racing pulley set for the Acura TSX would work on the Accord

i got the UR underdrive pulley kit installed into my TSX over the weekend. here's a pic of the end result:

granted, i have an AT, but i could definately feel a difference after they were installed. for one, they're substantially lighter than the stock pulleys. you can definately feel the engine rev a little faster and it just feels more peppy overall (horrible term, but it's the only one i can think of). it almost feels like the car pulls a little harder.

i'm pretty happy with the results.

Congrats and enjoy! Looks pretty schnazzy too :) Mark W.

Nice! What kind of gains did you see? Also, any adverse effects from the different alt. pulley?

I'm also curious to know if there are any adverse affects from the different alt. pulley.

i did not get a dyno after the install, so i unfortunately don't have concrete numbers to back up what i'm feeling at the wheel. but i'm pretty confident that the engine revs a little faster and harder than before, and just has a little more oomph to it. i actually found a dyno on the unorthodox racing website. it's probably a MT.

as for the impact of the alternator, i haven't encountered any problems. i don't have an aftermarket stereo system (supposedly <600watts is ok for a stereo). everything is stock. if i happened to turn everything on (wipers, headlights, fogs, radio, A/C blasting, etc...) maybe there might be a greater chance of something adverse happening?

do you think a voltage stabilizer/grounding kit would help?

If you had everything running, the load on the alternator would likely shorten its life. That's why having an aftermarket stereo is especially bad with a slowed-down alternator. Having one with a stock pulley can kill you too- mine with only 800 watts RMS (and NEVER turned up higher than average listening levels) with a 1 Farad cap still ruined my stock $900+ alternator in a year and a half (the exception rather than the rule, I know, but damnit!). Thankfully, my business partner rebuilds alternators for a living! :) Mark W.

It might. It helped out Bioevolve with his FG issues.

wow. i'll have to keep an eye out for any issues then. i'd imagine they'd show up over the longer term rather than now since the pulleys just got installed.

thaduke2003

They'd be longer term, yes. The grounding kit and all should help a bit, but overall, you're not going to kill your alternator next week or anything. Will it last as long as with the stock pulley? No. Don't sweat it too bad, but if you have an alternator problem, swap the pulley off and bring it back to the Ac :) Mark W.

I think I posted the UR vs. stock pulley diameters before, the alt. pulley size isn't much different, just lighter. I've been running the UR pulleys for years now with no adverse effects. the steering feels just slightly heavier but not in a bad way. I don't see them as a real power adder, just less rotating weight for the engine to push so it revs a little freer, esp. from a standstill.

here is a comparison that was made between the stock pulleys and UR kit for the TSX (same as the RSX type-s). this comparison was made by poster jtso from acurazine.com when he installed the kit on his car.

you'll see the weight differential is substantial, and like rsxmachines mentioned, the alternator pulley size is marginally different from stock. agreed, it's not going going to add huge HP. but the car just feels better and seems to pull harder.

will this work with a 07 accord mt? i figure it should since they are simmilar engines, but better safe than sorry.

you can just ask unorthodox racing directy if they have an application for the 07 accord. looking at their website, it doesn't seem like they offer anything right now, but just call and confirm with them. they seem pretty friendly when i dealt with them.

you can also try some other companies. i know NST makes a pulley kit for the TSX and some older accords. sometimes they make custom pulleys for ppl with forced induction. of course, you have to probably pay more since they're making it for you.

i think AEM has some pulley kits too. you can check them out.

just got off the phone with unorthodox racing and they said it is perfectly compatible just specify rev a when purchasing it. they redesigned the part to be compatible with the newer models and still have a few off the old ones left.

sounds good mang. go for it!

Might have to consider than the UR one has no resonance stabilizer. Could cause problems in the future. Thats the only downside I see.

It will USUALLY only be an issue if you also run a lightweight flywheel and don't re-balance the rotating assembly. Also, it can cause a random or all-cylinder misfire code CEL because the crank is spinning too quickly for the sensors to get a proper reading, so the ECU interprets this as a problem- Mark W.

already ordered, i will fill you guys in on the install and differences in performance once ive got installed.

so the pulleys are installed. it took a couple hours for the install, but for the most part went smoothly. i noticed no difference in the power steering or ac but a noticeable difference in acceleration! ive only been for a test drive thus far but im impressed and very pleased.

yep pullies were a great mod,

agreed. the car definately feels more-responsive when it revs.
