yea .2 is better then what 4.10s got me

 

i got mine for a steal for $100 so i couldnt pass it up and i gained .2 in the 1/4

 

average is .2 tenths?

hopefully we can get some weather like i did last time... -200 to 0 da would be nice so i can get a good comparison.

and right... with probably only like $200 more than the udp's i could get a set of stock heads and get someone to work them and pickup about the same. (which is the next thing btw... trying to figure out if i should just get some 5.3 tea heads, anything's better than what i got really).

I'll know by the end of the week if my gas mileage is slightly better... i doubt it will be much better tho.

 

If you changed your oil you would gain .2 in the quarter mile..............

 

I'm still not buying it

 

not worth it on a daily driver....IMO....still probably not worth the cash even on a strip vehicle, unless your loaded and dont have to worry about money at all.

 

i have had the asp underdrive crank pully and the overdrive alt. pulley for several years. i have not noticed any issues with overheating due to slow waterpump rpm's orslow speed steering issues. i have a stock idle speed. now, when my e-fans kick on, the volts drop just slightly and come right back up. windows roll up fine...... i gained .6 in the 1/4 with 4:10's and the UDP..... which is irrelevant, but these are just hard facts experienced by me.

 

thanks yea, i think you got your point across.

but what I dont get is your negativity towards something retarted as a freaking set of udp's. We have people talking about real life results... so you're not saying you don't buy into the fact that this might or might not help. You're saying that you don't buy anyone's bullshit.

 

I'm not trying to be an ***... but have you ever had them on anything you drove for a dd or at the track? Or are you just saying why would anyone spend almost $300 on something that may or may not drop something as measley as 1 to 2 tenths in the 1/4mile?

 

i was about to say the same thing. . . i agree with you 100%
