i was just wondering how much HP i would get from the UDP, so i went over to UR's site, and here is the weight difference between the pulleys:

stock : 7 lbs 1.4 oz
UR UDP: 1 lbs 8.7 oz

thanks to my TI-83, the weight difference is 5.54375 lbs, and UR claims "An average of 2.7 HP is gained from every pound lost off the crank shaft." so i'm doin the math, and it looks like i'll get 14.968125 HP, or in other words, 15 HP from this. does that sound right? i dunno, but for some reason i didn't think i would get that much. and please don't tell me to go get a dyno cuz that's not a possibility. here's more from UR's website:

"Unorthodox Racing lightened underdrive pulleys can provide gains of 5 to 12 HP and 4 to 8 lbs.-ft. on normally aspirated engines"

this seems more reasonable.. but then again there's the TTZ that got 37 HP

anyway, i ordered one, and it should be here next week

 

in a week you will find out first hand,it will be good dont worry

 

Cool

i ordered one too.. should be coming in soon as well..
keep in touch and let me know what u think. and i`ll tell u what gains i feel when i get it.

 

yeh, i can't wait

i was just thinkin, ya know, 15... wow

 

down boys ,down ,dont hype it up to much ,you wont be doing burnouts ,but you will be put back in your seats a bit,with quicker shifting

 

I have heard that a UDP provides more of a gain than a full exhaust.

 

yeah that sounds right,but both combined would be great

 

cool, i already have a cat back, hope this will give me a lil more "ummph" at the start

 

In my opinion if you have a auto the gains from the UDP will not be as noticeable as a 5spd. The torque converter robs too much from the drive wheels

 

yah i know stuipd auto tranny
oh well im looking for parts to slowly build my collection of parts to do a 5spd conversion

 

hey candiman, how much are the camber plates?
