aem vs unorthodox - Honda Prelude Forum

h7y · 11-12-2001, 08:01 PM

I see on sites listing unorthodox pully for an 8-15hp gain, this sounds rather out there, but they are twice as much as AEM. so is unorthodox that much better? People say they get like 3-5hp with aem pullys.

I believe the Unorthodox setup involves 3 pulleys (crank, alternator, and P/S pulley), while the AEM has 2 pulleys (alternator, P/S). I went for AEM anyways. Harmonics (71dsp can tell ya) is not one to be trifled with.

Try a search. I have wrote so much on this topic that you will find plenty of material to read.

someone explain "harmonics" please, and what is P/S? btw thanks for the quick reply jacques

Power steering.

The keywords are Unorthodox pulleys. Here's a post about one of them, and 71dps talks about harmonics a little: Recipe on modding prelude's engine

i have the AEM...i like it...

but if i could do it over, i would get the UO's

damn...wiht my auto...i need that 10lb of torque and 15 hp!!!

well, i heard ppl saying the solid pulley like unorthodox is going to damage the crank in long run. is anyone can gimme idea that i still need balance the engine if i take it out and back to factory pulley??

Ummm yeah AEM pullies really suck. Go with uo or somthing else.... anything is better.... The guys at many proformance shops down here wont even sell them or put them on. Huge diffrences in AEM and UO and no the gains are not that far out there.

Thanks and I know I'm gonna get dogged for this.

Bluelude28 · 11-14-2001, 07:38 PM

Well I think this is more of a matter of will your lude keep on going w/ the added horses provided by the Unorthodox set. Cause no matter if they're gonna give me 50+ horses...if the car's gonna give out then I'm not using them, period. So yeah obviously AEM won't give ya as much of a performance gain, but hey at least the car's gonna keep running!

IsamuBlue29 · 11-14-2001, 08:07 PM

heh i wasnt saying that UOs were better or worse i wouldnt put on a mod that would kill my car either heh to be 100% truthful i would put either on my car.... so heh its all cool.... sorry for the confusion...

has anyone had an unorthodox pulley that's gone bad or done any damage? is there a work around to this problem that it has?

71dsp · 11-15-2001, 04:27 AM

Try searching. I have posted LOTS of information on this subject. A solid crank pulley is responsible for ruining my crank bearings and oil pump.

illusion · 11-15-2001, 05:11 AM

so how about using the unorthodox pullies but without the crank one? i guess thats defeating the purpose of buying the aem though.. unless they are THAT much better
