from what I've read, I think closer to 3 hp

Maybe - if the AC was running & you had a huge alternator load.

Just turning off loads will also give back lost power.

I'm pretty sure it's a well known thing on this forum that pulleys do in fact give you 1-3 horsepower tops.

UNORTHODOX ULTRA SS PULLEY SET <<<how do you feel about this set

its a known fact that you need every hp out of the 8

I don't have the pulleys, but there are plenty of people who have them. Get them if you want them, in the end, it is your decision...no one else's.

the gains don't seem to justify the cost, but if you want max gains, look for the largest under driven % and buy that.

08-21-2007, 01:25 PM
I can tell you which set ppl tend to like the least.....Greddy. If I ever buy them I'm going with Unorthodox. If I only want the crank pulley I'll go with AP.....does this help.

As far as I can glean AP is the preferred set (well only main pulley actually) cos they are OK and pretty cheap for a small minor effect mod.

People who are really fanatical have got other ones too, and most people seem happy if not whooping for joy.

You aren't going to gain 8-10 hp. 1-2 is more like it.

The UR set looks real nice, but its rather pricey, and you aren't going to get much better performance.

I have the Agency Power crank pulley. I didn't notice any power gained in the "butt dyno", but I wouldn't expect to notice 1-2 rwhp anyways so I wasn't dissapointed. And its only $125 bucks, might as well, it's cheap.

UNORTHODOX ULTRA SS PULLEY SET will be my choose i guess

but is the AP more under drivin

a total waste of money, 1-2hp is not worth a penny. you wont see a difference in any dyno. take 2 identical cars, one with pulleys and one with none, neither will pull on the other. temperatures, a big dinner, or even tire pressures have more affect then pulleys.

someone on this site actually did that with the AP pulley. Even to the extent of taking it off again then putting it back on .
Conclusion was that there was a good 1/2 car length gain on the 3rd + 4th gear pull up to about 100mph . This would suggest the 1-3 hp figure is about right .

The AP is the cheapest & will give as good if not better gains than the others so thats the one I went for .

hmm thats very surprising. any video of that?

on a type-s, a thicker intake manifold gasket net's 1-2whp proven on a dyno. but never once does anyone say it will pull on one stock type-s or another. hence why i dont have it in my list as a mod added.

i would think 1-3hp is equivalent to a 100lbs or less passenger which would do little to nothing. in fact, adding a cold air intake to a type-s nets 7-8whp and again, the pull between a stock and a type-s with a cold air intake is negligible. fender length at best maybe? but not half a car.

but if there's video proof of a pulley doing that, im willing to see and be proven otherwise.

where is this majical intake thet adds 7-8hp ? No-one on here has been able to show those gains with just an intake.

I'll see if I can find the relavent post for you (no video though) . It turned into a bit of a shit fight with a sceptic in the end but I believed the guy did a good test .

Agreed. Though Team has got me with the search before, there are several very LARGE threads with all the data from the Pulleys.

Or you could just ask MM!! :lol2:

Which is interesting because If I understand it right you basically have a custom intake, custom exhaust, custom header, an actual racing pulley and a tune for your power mods.

haha oops, forgot to say rsx type-s, didn't mean rx-8 type-s lmao. sorry bout that. but anyway 1-2whp should be the same to each car. i just used my own car as a comparison. i didn't compare rsx to rx-8, i just talked about what i knew for sure personally. an rsx-s with +1-2whp doesn't pull on a stock one.

so from pure deduction i would also assume that an rx-8 with +1-2whp wouldn't pull on a stock rx-8 either.

but again, my opinion is by no means solid since im somewhat expecting to be proven wrong.

nah actually its a great car and all, I sold mine for 12k, it was fully modded, but I thought it over and my AT rx8 was a better option than it, for one thing at least I can use it for stuff and don't have to re adjust my seat everytime someone wants to climb in the back, and I slid off at 40mph......its just retarded, and I had a damn turbo

I was one of the first with a pulley system. There is an old dyno on here and it showed about a 1-2 hp gain with the SR Motorsport set. I have since taken those off & replaced them with an AP unit. It does give about a 2 hp increase. But for a little over a $100 & it's only one unit making it easy to install I figured why not.

the "interesting" part, is the assumptions made, about the mods you mentioned he has

what I don't get is that mr Baghead is possibly on to some really good mods but refuses to share them with us .

like that^^ Now i do tend to agree with Brettus.. but its just an assumption

i havent paid particular attention to Team's threads, but he hasnt ever given me the impression that he has found any "holy grail" of mods****, or any magic combination of bolt ons....

**** except for possibly the Reflash courtesy of Cobb :Eyecrazy: but thats a holy grail for a different reason which Team has no roots in, FI

lightweight wheels or a flywheel wont dyno much different either, it doesnt mean they dont necessarily do anything.

Just like the man said, on a dyno a 3000 pound car and a 2200 pound car wont dyno any different if they have the exact same engine, but it doesnt mean that they wont accelerate faster.

A chassis dynomometer will not register a 1-2 HP gain. Its deviation is around 3%, which is about 6 HP for an RX-8. Any gain that falls below that cannot be effectively measured on a Dynojet or something similar.

Pulleys do nothing for the 8 but bring bling. The only "test" was a completely data-free drag run by a forum member. Even the race fell into the statistical error.
If you ever feel like installing a hydraulic power steering system, then you might want to think about an underdrive set.

haha nope, everyone has their own opinion on whats good or not. but curious why didn't you get the mt rx-8, that would have been a very very nice change of cars? seems like an AT rx-8 would be huge downgrade to me from a boosted type-s? and i dunno about you, but my type-s which is a hatchback can hold double what my buddy with an rx-8 can hold when moving back to college.

theres no way you can hold more stuff in a trunk space, when i can fold down my rear seats, in fact one of the biggest reasons i got the rsx type-s over a wrx was that feature alone, to carry hella stuff since it was a hatchback.

I have to reread the goodies thread. Perhaps I missed something :dunno:

Maybe I misunderstood your reply, but every part made for the RX-8 starts off as a custom piece, the difference is whether or not they get produced for resale. I've never made any strong claim on how much any one mod contributed to *my* current output.

My *custom* intake is just a filter on a stick, my *custom* header is nothing more than a collector manifold, my *custom* exhaust is just a 3" pipe with high flow cat that splits into a pair of 2" outlets with short Supertrapp mufflers. My pulley set would only be considered a *race* set in that it deletes the AC drive pulley, which you can likely do with most of the street sets or even the OE pulleys. Even the PCM software upgrade, which seems to make a strong difference on a bone stock car, does not contribute any large gain to my particular setup.

The interesting part for me is the several people who get kudos for talking a bunch of hyped up theoretical textbook generalities without having ever produced any significant results. I've seen proven results that go against a lot of common thinking here.

MM - maybe it was data free but it did seem like a pretty good test that he did and it fell within the realm of believable . No-one else has gone to similar lengths to test minor mod like that .
If he carried out the test as he stated - there is a very high probability that his result was accurate . Then it comes down to - was he just bullshitting about the whole thing ? I didn't think so at the time .

I might be misusing the word custom and despite all of the technical jargon I typically believe the people who are actually racing their cars. I am actually using your setup as a bench mark for my N/A 8. I am hoping to do all of the same mods but not "built by me" versions.
