info on new FZJ80 SUPERCHARGERS finally

[george_tlc]

Now that a fresh batch of s/chargers are hitting the street and folk are planning on their installs, I wrote up my install experience (several years ago) -> Kazuma Supercharger Install

Might help folk plan their install and prepare for what awaits them.

I have since replaced the ringed fan (wonder if that is still supplied in the new kit) with a non-ringed fan through Dan and also a new blue fan clutch.

Also, before installing your new s/chargers please make sure that your cooling system is in tip top shape and that you have no other engine/drivetrain issues. Our 80's are a lot older and higher mileage than when the s/c was first available...

cheers,
george.

Great info George !, I am researching as I just bought my SC and will install it myself (I have no money left ), plus it is 50% of the fun. The other 50% is going fast and furious

It sounds you ran into some troubles, I hope some of those are fixed in the new kit (i.e it will be nice to get pre-made extension harness for the TPS/IAC cables).

I will make a tool like yours for the Crank pulley bolt. I was wondering if you used a 1/2" breaker bar to get it loose?. I've read that everybody uses a 3/4", but I don't have one.

Also, does anybody knows if places like Napa, Autozone, etc? loan a big enough torque wrench for the crank bolt ?

I however, don't think there is much risk of superchargers needing much in the way of service parts.

This is a good observation. We have a lot of 'Mud members with the original TRD S/C and I cannot recall a single thread posted by anyone having an issue with the S/C. Not even the belt.

I agree that someone should start a thread requesting comments on the reliability of the S/C. That would be interesting and relevant since this second run is now available.

I wonder if this S/C belt is the same as the old Kazuma S/C one? my toyota dealer cant get a belt for it, and I need one since it came off at the drag strip.

What would typical acceleration times be vs stock on 0-60 and 1/4 mile. I'm just curious as to the improvement vs stock and have not seen any threads in search with this info.

7500 lb rig here with original TRD S/C ran the 1/4 in a high 15.

 

[skunkworks]

What was stock

 

[colter]

not sure on stock numbers. didnt own the truck then.

sorry to hijack the thread

 

[Romer]

I have never done the test you ask. It is a lot faster than stock.

I do have the two datapoints. With the SC you are as fast as a 100 series with a V8.

With a SC towing a 3000 lb trailer up a mtn pass, you can still go faster than a stock 80 not towing. At least that was my experiance on the way to and from Moab the last two years

This thread is making my sick, I've got to quit looking at it or Dan is going to have my credit card number soon. I couldn't imagine having that much power going over passed. I traveled the passes outside of Denver on my way home from buying my 80 and it seemed kind of like a dog and that was with 265 michelins.

I know that when adding a SC that you're obviously not concerned about fuel conservation but with fuel prices like they are now I can't help but ask.

Bases on the numbers that have been posted on these new SC's, do they seem similar to the power the old SC's produced? If so, can anyone give some before SC and after numbers for gas mileage?

I'm getting very antsy but I'm afraid that the will divorce me if I pull the trigger on this one.

Nicholas -

I don't know specific numbers...but, based on the feedback everyone has offered about the S/C I went on faith alone. I have not heard anyone say..."yep bought the S/C...wish I hadn't."

I'll see if I can get a dyno done on my LC now and then when I get back and get the S/C on I'll run it again. I believe there is a all wheel drive dyno in Memphis...if I remember correctly.

Cheers.

I know Landtank isn't a fan of S/C's but I'm not sure why. I know I'd die for one. I remember seeing one for sale right after I bought my 80 in April of 2006 but I didn't buy it. When I found out they were discontinued I was kicking myself. Now that they are available again I am worried I will be kicking myself again in a year if this ends up being a limited production run.

My first LX 450 had SC installed at around 60K miles, and I bought it at 130K. No problem at all!!!

Regarding MPG -
I got about 16+ on all freeway and Local is about 13 to 15 on my last stock LX450 with SuperCharger. I will say, it’s very comparable to NA engine.

Depends entirely on how you drive it.


Prolly ~10-14 mpg.

Dan - Sorry I should of make it more clear... My last LX was all bone stock...



Here is Phil’s trip to Canada a few years back....



https://forum.ih8mud.com/showthread.php?t=18753&highlight=mpg



"The best MPG was 15.3 and the worst 11.6 (normal MPG for around town) with an overall average of 13.5." The truck has 6” Lift with 37” tires and other goodies with total of 7080 lbs. From what I have been reading from mud, this is probably very similar to N/A engine built truck.

I've had my SC mounted for 'only' 37k, but I can add a few comments here.



First, my bet is that the head shave caused a CR bump, which causes the requirement for premium fuel. I have run midgrade in my rig when I know it's not under severe duty, and altho you can tell the difference in power, there is no pinging at 6.5psi.



Second, meth injection is *a* method for controlling ping, but you can also add an intercooler, which should all but eliminate the pinging other than at heat soak rock crawling (and you can install an IC fan for that if you desire).



I posted up my gas mileage was no better/no worse than without the SC. Even Mild on-boost runs up hills on the highway didn't change overall mileage, which I'm sure is due to the lack of kickdown of the trans. The bypass valve on the SC really means you only have 1/2hp drag on the engine when not in boost. That's less than the A/C compressor draws. That said, winch, oversize tires, etc, puts more load on the engine = less gas mileage. I run stock tire size and weight, a key to gas mileage IME.



30% increase in HP with a 1 day install is nothing to be bummed about. And the torque is what makes the SC desireable IMO, not the HP.



Regarding the ecu and timing mods, it might be wise to either put a wide band o2, and/or dyno test the rig to see if what was done, really helped. The head shave concerns me more than the other mods.

Romer,
I'm curious about how the truck performs on long freeway grades or mountain roads. That is the time I really wish for more power. For example taking the 330fwy up to Big Bear, Ca (7,000' of twisting elevation gain w/ the occaisional passing lane) - there is a sign at the bottom saying "turn off AC to avoid overheating" and I've seen many pull off w/ overheating problems.

does the SC cause more heating up of the engine with constant boost like this? It is about an hour of this type of climb.

What do you feel are the real-world drawbacks of the SC?

thanks

Thats why I and others also isntalled an AUX fan. It does add more heat, but the JDM Aux fan keeps everything in check even up the mtn passes. Thats also why I isnatlled a seperate Temp gauge so I could better monitor that condition as there are things you can do (like turn off AC) to manage the engine temp.

 

[landtank]

I know Landtank isn't a fan of S/C's but I'm not sure why.

I wanted one like everyone else. I figured it was a Toyota product and expected it to be of a certain level of quality. I looked into it and IMO it falls short of what I would want on my truck.

There is no intercooler with the kit
There is nothing in the way of fuel management, not that it's an issue any more.
And the reports of engines running hot are quite common.

So yes you can bolt this kit on as is and it will work but as owners have reported you will likely start wanting to add additional components to help with it's short comings. If I'm going to do all that then I'll just do my own thing from the ground up. I really enjoy the process of engineering something and the satisfaction I get from doing it myself, but going in and fixing someone else's design flaws or short comings bugs the hell out of me. If I'm going to buy a bolt on kit then that's what I expect, bolt it on and it's done.

Like anything else, not everything is for everyone and this just isn't for me.

That was the issue I saw with mine and heat. I had a boost gauge on mine and learned on long, slow grades to use the gears to keep the boost low and that would keep the temps from creeping up over 210*. If I didn't take it out of OD and kept the boost pegged at 7-8psi and the AC on, temps would go up to 220*, I never pushed it beyond that. Mine also had an intercooler on it that we figured dropped the IAT 10-15*. So, without some type of auxilliary cooling, I'd be extra careful.

But for scooting around town, it was a BLAST. There are a lot of ricers in my neighborhood, I used to love to scare them and shoot a 3 ton truck out in front of them.
