Super Charger Pro and Cons

[Ride_Red]

Is the 1st Gen TRD Supercharger just a simple bolt on or is there more...?

I know gas, little bit of noise, etc..

But do I need to do major stuff like pull and upgrade tranny, torque converter, service it every 25k and any other major stuff

To be honest this is going to be a build for a spare truck, not an every day ride and it will see limited off-road use. More for just a spare back-up and the occasional towing.

Thanks

I think most people would say the "noise" is a pro.

You're going to need to do some fuel work. URD 7th injector etc...

I believe one of the main cons of the 1st gen supercharger is that you can't change the oil in it yourself. You must send it out and there's only one company currently doing it. I think the cost is around $4-500.

Other cons include tuning issues (many people run lean) andhaving to run premium gas.

That is incorrect. You can change the oil yourself on the 1st gens. For a full re-build it has to be sent in. But its pretty easy to just change the oil.

But you are spot on about running lean.

Ahhhh. I knew it was one of the two! Thanks for the correction.

You can change the oil yourself. The S/C just needs to be pulled from the truck to do so.

Like i have said in the past. The 7th injector is not required to run the TRD Supercharger. I have been running mine for the past year and a half with no additional fueling and the past 6 months have had a 2.2 pulley on it. No lean out and no ping.

x2.. I also had an external tranny cooler to try to help out with tranny temps but I would get one of those regardless if I had a supercharger or not.

I guess i should mention that i have a manual so that was not needed for me. But yes I agree with you. Supercharger or not, ext trans cooler is a good idea.

My dad had one on his, he made the mistake of putting cheap costco gas in it, destroyed the fuel injectors. I only put premium shell/chevron in mine.

Even though you do it, doesnt make it smart or wise. Ive been tuning cars for over 12 years and you cant hear or feel detonation. Only way to see it is if you have WBo2 and a knock sensor. Once it pings its really bad and you can be causing damage slowly too the motor. But I may be wrong you and have a WBo2 at good afr's under boost.

The most damage without the 7th injector is caused at low rpms and low throttle. The AFR map of the stock ecu cant keep up with the boost at low rpms and throttle and can cause detonation that you cant feel. This will slowly eat up the valves till you loose all compression. Ive had this happen after 3 years of driving a car with a lean condition that could only be seen on a WBo2.

So its still wise to run a 7th injector and or some type of engine management with larger fuel injectors and a wbo2. IMO I would never run a boosted application without fuel/timing control, wbo2, larger injectors and e85 fuel!

What's too lean? I have no fuel mods, and during low rpm low throttle situations I stay pretty much right between 14 and 14.6. I'd say for 75% of my driving it maintains 14.6. I'll get about as rich as 11.5 during hard acceleration, and will VERY briefly go lean to 17 right when I let off the gas and decelerate. But it quickly goes back to 14.6.


Seems to me that unless stoich is actually too lean for engine health, the stock fueling can do just fine if you're not driving the truck hard.


Also, the 7th injector doesn't even do anything at low rpm low throttle. The only benefit to having URD stuff is the calibration of the fueling....it might not try so hard to keep you at stoich. But the actual 7th injector isn't doing squat at low rpm low throttle.

As soon as i jump on it, my AFR goes to about 12.0:1 and stays there pretty much through out the rev range.

I've said it before and i will say it again. The 7th injector is a good thing to add and it allows you to produce more power. However there are so many people that say that you basically cannot run the S/C without one and that it simply not true. The stock ECU does a good job of adjusting the amount fuel for the increase in airflow.

Living at higher altitude you usually won't need any extra fuel mods since your SC isn't making the same boost as it would at sea level since naturally aspirated motors lose a little bit in the thin air.

For you guys that are monitoring there afr with widebands are you using any air flow converters or is it simply off the stock ecu? I find it hard to believe your running such a good map with the stock ecu without any overriding. I use to run an air convert on my turboed car before going standalone. It wasn't even drivable with the stock ecu on its own so its interesting to me that you can slap on a super charger and have such a good map with stock ecu/injectors.

I may be picking up a 1st gen kit this week...

I will need to add a 7th injector kit, AIR / FUEL sensor, AIR / FUEL guage.... anything else?

WB02, not just a fuel gauge and your good to go.

Yeah they work pretty good, had one before in my DSM. Only issue is they used to have problems logging with some software but I believe that has now been fixed. I would maybe look into the supercharge threads and decide if you really want the 7th injector. I believe larger injectors and a good piggy back would work a lot better than adding the 7th injector, but thats just my opinion.

It urks me that so many posters on here make it seem like your 4Runner is going to explode if you don't add fuel mods. You do not need anything beyond the Supercharger. Toyota even states that no fuel mods are necessary. Case in point, my 4Runner has now had almost 100,000 miles on it with the SC and no fuel mods. It does state to use 92+ octane fuel though (I can only get 91 in CA)! So many people try and cheap out with 87 and then complain when the engine pings.

If this is an extra vehicle, save yourself $1,000+ and don't mess with the rest unless you want it later. You can always add it if you want more power, that's the main reason for adding the URD parts along with a smaller pulley.

Now all that being said, I am looking to add more fuel and a piggyback controller in the near future. For more power though, nothing else.

Cons: Lighter wallet.

Pros: It's a ****ing supercharger! :zoom::eyebrows:
