Not tryin to be an ******* but how can you say that when you've never done it and obviously not talked to anyone who has...
Without this getting personal, that's all I'm asking for, actual testimonials. I'm in no way an expert on all these mods; I read as much as I can on a topic, listen to others, and yes, I have talked to folks that have done the mod on their vehicle. Most did it to improve cooling efficiency, as the AC in these trucks seem to suffer in the hot southern summers. On an episode of Gearz (this past weekend on Speed), the host talked of an electric fan kit they installed on a Chevy truck. It did not show any significant
HP gains, nor did it show massive MPG gains (he reported .3 per mile, or 3 miles per tankful on a 30 gallon tank). Not saying it does not reduce drag; the show did state it provided better AC condensor cooling functionality meaning better AC cooling was obtained in the summer. Now if the electric fan kit is combined with smaller pulleys, then perhaps the gains gets better, but again, more money is spent.
This mod could
be a lot of money to spend, but not much bang for the buck. Most here agree that when you get into this price range, a tuner is a best bet. Another good case is a Cold Air Intakes (CAI); many go out and buy the kits and install. It was shown and agreed to on this forum that the GOTTS mod on a stock air cleaner box is just as good, and saves you around 150 bucks.
Many performance parts on a V8 can provide significant gains on a V6. My 4.2 will never beat the 5.4, but it can benefit just as well with simular 5.4 mods.
How is power being measured with an electric fan kit install? You really need dyno before/after readings on this mod to prove significant improvement in HP/TQ. I've not seen these posted here.
All I'm asking for is honest testimony, and hopefully with a bit of fact to back it up.
