thanks very helpful! If i got the under drive pulley is it a must to get the shortened belt? and which one in theory could create more Hp one a modded vechicle?

 

using lighweight pulleys r about 2lbs less then a stock pulley so it puts less load on ur engine, frees up a free hp if you modded, and helps u rev out faster,

based on way mods i see u hav and r goin to get, a lightweight pully will give u a little gain and yes u need a shorter belt but its just a little short, but do this add a last mod b/c price/power ratio u dont get much

 

yeah you wont really see any hp numbers but you will feal a difference I have both udp and alt pulley and the car revs a lot faster and please for the love of god dont buy the shorter belt online go to your local auto parts store and buy one for cheap

 

so really the best combination would be both? and factor a tune after the pullies it make turn out to be quite a power adder...

 

2.8" pulley is the way to go

 

It would be if he was supercharged

 

Than a pulley alone won't make a significant difference...

 

yes for me it could lol i would love to have a 6 rib setup and a sligtly shorter belt so i dont need to special order one soon.

 

You sir are correct

 

Would there be any difference with the lightweight crank pulley and alt pulley?

 

By having them lightweight the engine has less of a load to try and turn. This allows the engine to spin faster thus quicker revs and with less of a load more hp(very little tho). Do it more for the revs so you can get to your powerband quicker and thus faster 1/4s!

 

ohmigosh, again...............

 

Hai!

 

been there...done that...not worth it...but whatver floats youre boat

 

So its a complete waste of time and money? It sounds like something I would like to have. I would love it if my car were to rev quicker.

 

sounds like someone has already lectured about this before

 

have you looked into the ati super damper?
expensive but well worth

 

Please do tell....

 

the gm drag cars run the super damper with no problems up to 1400 hp.
it is already balanced and can with stand high rpm abuse.

i dont know as to how much it weighs but its better made than most

costs bout 410 through summitt racing
