TRD Supercharger
I'm considering getting one for my 99 3.4L 4runner... has anyone installed one? Is the increase in HP worth the price? Where's the best place to purchase one?
thanks in advance guys.

Try using the search feature for this topic - you will get many hours of reading material.
Also, check out Gadget's website - he is one of the guru's on the supercharger.

Combustion, the search feature will provide loads of useful information. Here is my 2 cents from 6 months and 10K miles ago. I love the S/C but it's more of a journey than a bolt-on once and done modification. I am now convinced a fuel modification is required. I will probably go with Gadget's kit in a few weeks.
After 2K miles on my supercharger I hope to summarize my thoughts and experiences for those considering taking the plunge. I agonized over this decision and read everything I could. The problem is that the information is scattered all over several boards. Here’s my two cents in one post.
I found a slightly used supercharger for a reasonable price through Customtacos.com. The guy was in a pinch, we both got a fair deal. After reading everything I could find, I installed it myself in about four hours. It is not a difficult install, basic tools and some common sense. You will get to know your 14mm wrenches very well, add in a torque wrench and a decent set of metric sockets and box wrenches and you’re good to go.
The day before the supercharger installation I installed the cooler thermostat, flushed the radiator and installed the cooler plugs that TRD recommends and drove the truck. I am cautious about making too many changes at once. Both jobs were fairly straight forward, again, do a little research. I had 35K miles on the truck, and both services were due.
The first thing you notice is the supercharger wine, my son says it “doesn’t sound like a truck any more!” It is a noticeably different sound!
I am fortunate enough to have 93 octane gasoline available. It’s roughly twenty cents a gallon more expensive, which translates to $3.00 a week to my fuel bill. It’s the price for a little fun! Gas mileage is roughly the same as long as you keep your foot out of it! The first tank was down about 2 mpg. Then again, that tank had about as many WOT as I normally do six months! I have yet to experience any ping. I consider myself lucky! The hill where I normally drop it out of overdrive, I can climb in overdrive without any ping. Maybe the 2001 computers can handle the supercharger better or the added torque makes the climb much easier. Overall gas mileage is down about a mile per gallon.
Yes, WOT is a lot more fun, but the thing I notice more often, I’m easy on a car, is the added torque and effortless acceleration from 45 mph or so to 65 mph on the highway. A very light touch on the gas pedal and you accelerate very nicely. The supercharger does confuse the cruise control, it kicks in on a hill a little too aggressively now.
There is a down side. With the supercharger, the shift from first to second and second to third are very slow on the automatics. The Level 10 VB upgrade is clearly next project. I am debating the fuel modification, injectors and pump, along with one of the piggyback computers that are being evaluated. I’ll let a few other do the exploration for now!
Do you need it? No! Will you like it? Most definitely! If you consider installing the supercharger, add the cooler thermostat, plugs, an ATF cooler and the valve body upgrade to your calculation.
