Mod Questions
 

Hello All,
I am considering purchasing some new mods here in the next few weeks and I wanted to see if any of you have had any experience with them. I just wanted to know if you think that they are worth it. I am considering a set of Pulstar spark plugs. They would run about $110 for the set of 8. I have heard a few good things about them but not really enough to make a decision. I am also considering a set of BBK underdrive pulleys. Once again, I have heard some good things but not enough to decide if I want to get them or not. They would run me about $170. I havn't really shopped around very much on either of these so I could quite possibly find them cheaper. I have also looked at (but have done very little research on) a set of electronic fans to replace the belt driven fan from the factory. If anyone has had any experience with any of these please let me know what your opinion is. Thanks for the input!

I can only give you an opinion on plugs - stay with Motorcraft! Virtually everyone who has tried another brand has later said they regretted it. Really, if Motorcraft plugs can last for 70-75K (I think they want to change them at this point now to minimize the breakage problem), they're the only thing I'd consider using.

Pulleys and E-fans can be a GOOD mod. But, if the fan motors or bearings aren't reliable, they're no good. And I think the air moving capacity of some of the fans are poor. Pulleys probably aren't likely to fail as long as they're "one piece" ones that can't "flex" under the strain of the belt. However, I don't have any good data on these. 88Racing, one of our stellar Moderators on this forum has installed pulleys on his truck, so he has some valid opinions. I think he got his from Troyer. I think there are a few who have installed E-fans too. Someone will give you opinions on those soon, I bet.

Thanks for the info. I still have some more research to do before I decide anything but this helps.

As far as your plugs and pulleys, I don't really have experience with that, but I can tell you if you do your fans right, you will be glad you did it. I have been told that switching from a clutch fan to electric fans takes as much as 20% load off your engine, which obviously give you more power and will also increase fuel mileage. In my experience, I had an '87 f150 with a 302 rebuilt into a 347 stroker. I got rid of my clutch fan and put dual electric fans on it. The difference was amazing. I didn't even make it out of first gear before I could notice the improvement. My fuel mileage went up, HP went up everything was a lot better. Electric fans are a mod that I would recommend to anyone. Just make sure you do it right, though. There are lots of different setups out there, you have temp sensors that go into you intake manifold in place of the stock one, or you have the small ones that just go into the radiator fins. You also have pulling fans and pushing fans, you have to figure out which setup is best for your vehicle. But either way, like I said, done right, I'm pretty sure you won't be disappointed.
