worth it?

 

After you have all of the other bolt-ons, yes!

 

it was my last bolton.

 

I was gonna make it one of my first bolt-on's.. nevermind then

 

NO. It does not have a good return on HP per dollar. I acutally ran slower in my camaro with the pulley at the track, which disapointed me because I did not think the weather was that different. Money is much better spent on about any other mod IMO. But if you are out of mods to do and have the money, put one on like I did. I am sure it is worth some minimal HP. Its easier to get off than the stock one.

 

that was my last mod on my 5.3, and i gained .2 in the quarter....

 

Every vehicle responds differently to each mod, some gain some loose. Good luck.

 

I think lq4 has better benefit of underdrive pulley than f-body.
when you add e-fan, it self can give you upto 25-30WHP. Not bad for less $1000 mods.

 

Ok not to bust your ***** but what have ya been smoking?Or
It has been proven several times that E-Fans give great gains in the quarter but the power on a dyno is ALWAYS less than 5hp and i have never seen more than 7tq. Normal gains are around 3hp 5 tq.
It's a great mod that frees up power and really drops your quarter times but gives you very very little ona dyno.

 

Oh yeah, for the thread at hand i did it to my truck last and it dropped my 5.3 a tenth. No idea on the 6.0 cause it went on same time as everything else.
