Which kits are good. and what kind gains would I expect from it.

 

Search here for "Underdrive", and you'll get a few pages of threads that all have to do with this.

And btw, it's 'pulley', rather than 'pully'.

 

Oh ya , can some one tell me when or how I will not be a trial user any more?
Want to reply to the classified adds.

 

GET UNORTHODOX RACING PULLIES.... i have them and they are great. i think there website says 8 hp and 12lbs-ft. i have them on my 98 Integra LS and they are GREAT

 

Pulleys are incredably over rated... most people see 2-3 hp with new pulleys. There is always a debate over whether or not an unorthodox pulley is good since it disrupts the balance of the engine.

 

And the ad for the "Turbonator" in the new Sport Compact Car says +35 HP. Should he get those too?

 

VERY overrated. Its mostly throttle response from the underdrive stress that is decreased.

 

hey i only go by actual results that i feel. i did this mod and i know what it did. I noticed more than 2-3 hp, maybe 2-3hp on a v-tec but on my B18B they are a good mod and a must for the all motor guy

 

also if you didn't know the pullies do no throw off the balance of the engine, its balanced internally

 

The engine is balanced internally yes, but it the unorthodox messes up the crank slightly so it does effect it. That is why it is a debate. Personally I dont believe putting an orthodox pulley will mess up the engine at all. I dont believe that there is enough to gain there though to replace it.

Come on man you will never be able to notice 2-3 HP... I mean even 10 is gonna be hard to catch. Everyone always "feels" an improvement because they just dropped some cash and want to feel it if you know what I mean. You body is only is just an okay accelerometer. You wont be detect the acceration difference from that little of power period. You just think you do.

I wouldnt even bother. I had the UR pullies on my Prelude and they made my lights dim a lot

 

i think the pullies are a no go for v-tec from what i hear but im shitting you guys when i did feel a difference with the pullies. my lights don't dim and i have a 450watt sub & amp. i know what my car does, maybe UR pullies are only good for non-vtec

 

i meant im not shitting you guys... sorry for the typo!!

 

Did you dyno your car to show the horsepower gain or are you relying on the "butt dyno"?

dyno results on unorthodoxracing.com say 8hp and 12lbs ft, look at it, im not lying, maybe they are but i highly doubt it becuase they would probably would get sued for false advertisment

 

Never go by a companies dyno... they are almost always in crank hp gains and beyond that they do stuff to claim they made more power than they do. Ive seen dynos that show a mufler making 25 more hp!!! Go by real world dynos. It is generally accepted that pulleys yield 2-3hp for the aem type and maybe slightly more for unorthodox.

 

I'd spend the money on something else, most people I know who got new pulley kits didn't notice any worthwhile gains.
