i just finish installing bbk pulleys on my 97 4.6 lariat and replace the fan with a electric fan i did feel the difference the pulleys add best 181.00 dollars spent thats just my opinion...

 

I put the Troyer Performance pulleys and dual 16" fan setup and feel the same way. Throw a BBK 75mm Throttle Body on there (our trucks run the same throttle) it will be the best $220 you've spent. I had to play with the idle screw just a lil bit otherwise it would idle to high if I set it to their specs, but you notice a big difference. I am going to find a used plenum and get it bored and polished to go along with the bigger Throttle Body.

 

its all ready in my wish list hopefully in a month i should have it

 

how much did you spend for the dual fans and where did you get them

 

www.troyerperformance.com, I love the company, they are constantly improving their products. The best customer service I have ever received. The last time I was home on R&R I installed the under drive pulleys and the electric fan setup. When I finished I decided to go ahead and get some more parts, so I submitted my order and they called me the next day and asked me what all I had done to my truck (they keep a record in their database) and informed me that I would be wasting my money at this point if I got the 90mm MAF, that I would want to upgrade my injectors first and get a programmer. They are probably one of the only honest company's left out there. I cant wait for my next R&R to get some more upgrades done. If you ever have technical questions they are there for you, I have even spoke to Mike Troyer, the owner on occasion to discuss what steps I should take next on my build up.
