Mike's got to quite his job. This just ain't as much fun as it would be if he were here...and it's too easy.

only having seen 1 SC engine which was Mike's, I'd say there is something a little squirrelly about his install. They had to lengthen the wires from the original TB to the new position which I guess is normal. However his tech just ran them straight to it right over the exhaust manifold without any support. He did wrap them in some heat sheild cloth but this made it stiff as a board. All this was hanging off of the connectors and when hitting a bump it would flex up and down with all that force on the connectors. No wonder he had a harness break there. I've done quite a few wiring changes on different machines and this one was probably the poorest executed one I've seen. That harness needs to be run so that it can be supported along the way to the TB and in a way that would remove and force at the connector from vibrations during driving.
Here's my take (not that anyone cares).
I'm removing my my TRD supercharger within the next 2-3 weeks. Yes, it will be for sale in this classified section and/or ebay
My install was fine and I believe the mechanic did what was required and followed George S.'s notes to a T. I was there and watched the whole time (for whatever that is worth). The wiring issue related to the IAC Landtank mentions was routed differently when the mechanic was done with it. Unfortunately the loser that re-did some of my wiring during changing up some dual batt mods moved the harness and told me it should be fine there due to the heat wrap (obviously I will never listen to him again since he seems to have messed up just about everything else he touched too). Also, it's important to note that the wires are not part of the blower, they are original harness wires leading to the IAC that we lengthened to fit the supercharger).
The power you get from the blower is awesome. Especially when rock crawling it seems as though there is great distribution of power all through the band. Keep in mind, this is not me saying I have scientific evidence, just my experience while wheeling. The blower gives you a buttload of power both off the line and while towing heavy loads up hill.
As most here know, I am on my 3rd 1FZ-FE. The first one crapped out about 1 week after I had the truck. Apparently the original owner never changed the oil in the first 35k miles. The second one I believe developed the piston slap over time due to continually running hot (remember, the dealer could not properly diagnose my overheating issues and this continued for about 9 months till Christo and Robbie looked at my truck for 2 minutes and had it figured out). By then it was too late. The fan clutch led to that failure. Did the blower contribute to the failure? Possibly, but can't prove it.
The bottom line with the blower is it does generate extra heat and reduces airflow in the engine bay at the same time. Since I have moved to the cooler plugs (another cbizkit recommendation), it had been running super smooth. The fried wires were result of the combination of bad placement of wires and me running the truck to the exhaust shop with no exhaust - just straight off the manifold). I think this exhaustless run had more to do with it since the next day when i touched the tube leading out of the bottom of the EGR modulator it just broke into about a thousand pieces.
From here, I'm going to run my 1FZ-FE stock for a few months before it is pulled and modified for the new wheeling season.

what else is needed? anything expensive?
just a pipe dream though as I do not have that kind of coin, maybe when I sell the house
but then I wont have a garrage to work out of 
On a 95 - 97: new radiator, new fan clutch, new water pump, tested and serviced fuel injectors, new fuel pump, boost gauge, and a proper fuel / air ratio meter. Oh, also an intercooler. Oh, also a piggyback chip to remap the fueling. Did I mention a EGT gauge?
Or, just wing it and hope for the best. Why be a perfectionist?

If it get to 100 degrees and above where you live and travel you WILL need to deal with heat issues with a supercharger. A supercharger works well for short uses of the power. You cant just stand on it all the way up a 3 mile hill. If you do your exhaust manifold will melt off the side of the block before you reach the top. Did someone say EGT.
To me the supercharger is much smoother aceralation with more available power thru the full RPM range then the turbo's I owned in the past(non-Land Cruiser).

Sorry, didn't make myself clear. I have a SC, and have crawled it to my heart's delight. I meant the turbo. How does it do crawling?

Kaderabek said:
The turbo works very well in the situation you ask about, and should make max boost by 1200 rpm, compared to the more linear boost of the SC.
Having driven supercharged 80's, I have found, after having turbo 80 4.5 that if no one had told me the 80 was SC, I wouldnt of picked it as such really........

You would have if you'd just driven a stock 80 though.

Well, if you come to Salt Lake, we can oblige you. I've got a SC, buddy's brother has a turbo. He's driven both trucks. I don't want to put too many words in his mouth, but it seems the turbo has a bit of lag, but once it goes, it screams. The SC has more initial grunt, but couldn't keep up with the turbo.
One of the funny comments I've had about it, is going to the dealership for service. I've got the Previa s/c badges on it (thanks CDan!). Someone always asks if it really has the SC. I guess many posers with Tacos and the like just order the TRD SC emblems and call it good. Why bother with actually installing the blower?

That's why I keep asking how it does in the rocks.
TJK
I have to laugh (LOL) everytime I read one of these "How does it rock climb?" If your cruiser, non-turboed and non supercharged can not crawl and runs out of power while in LOW Range, something is seriously wrong. Unless of course you want to bounce over the rocks as fast as you can, then by all means you need a Turbo

You're completely misinterpreting my inquiry. I'm not talking about running out of power. I'm talking about too much power applied at an inopportune moment due to lag then sudden boost.

I have a turbo charged 3FE and when wheeling, ie: usually in 1st or 2nd gear in low range, i have no turbo lag due to the fact that with 5:29 gears when in 1st or 2nd low range i'm in the 1000-1200rpm range and into the turbo's boost, so there aren't any sudden bursts of power, atleast no more then if you were wheeling a naturally aspirated truck that was geared nice and low, Brad.

I'm sure it's exhuast is fine, the truck is one of those with no expense spared. I don't think it's noticable lag, just "seat of the pants" feeling in acceleration.
And I don't think any combination, turbo, SC, or normally aspirated, builds enough power that fast to make it a concern about launching through an obstacle. It's not like they're running nirto-methane. Well, Cdan is . . .
I have crawled my SC 80 and been with a turbo 80 on the same run. It just does not make a difference. Stock, SC, turbo, they all work about the same when slow wheeling. If there was a problem with crawling forced induction we would all know about it. Gearing and tire size make the difference, not aspiration.

I have a question for you guys with the TRD SC, any pinging under loads such a passiing under light throttle or trying to maintain speed when climbing a grade?
The reason I ask is, I had a TRD SC on my 99 Tacoma Prerunner and it pinged heavily in both situations (I did not have the 7th injector kit that Toyota eventually released to address this).

Not me, but I also fill up with 93. Ouch.

Only issue I've ever had with the SC is heat. If I lug it along a steep pass it'll start to heat up, and I've got an intercooler on mine.
