TRD Supercharger truth

get what the original poster is saying, And it's what I have thought.
The trd S/C is a low boost S/C. Not a true super charger that gives at leat 10-15LBs pf boost.
I've always thought that if you put on a super charger, you had to do something with your engine bearings. He is right, cost Vs. outcome isn't worth it

 

I'm happy with mine.
I believe you expected too much and no doubt it's got to suck spending that kind of coin and not being happy.
I feel the power is a night and day difference compared to stock.Add in the SC whine and it's great.
No regrets at all here.

 

where did you get your piston heads and cams from?

 

Yes, its the M90 same internals that was used for the 5vz s/c.

 

oh my bad forgot. ha

 

mine has done me good (i have a 1st gen.) for the way i drive. im not a big speed demon but i like to get where im going. i love the way it gave mine the extra edge that it didnt have before. but for somebody who is looking for a fast ride....prolly not the way to go.

 

Instead of truth you should change the title to "Yeah, well, you know, that's just, like, your opinion, man." Sorry just saw the big lebowski again on tv.

 

Word. Too much boost kills engine life.

 

The original message compared a tacoma to a tundra. To keep things fair you might want to compare a SC tacoma to other similar sized upgraded trucks with SC.

My 2 cents: I've owned a lot of cars/trucks and every forum I accessed there's always someone wanting to stuff the largest motor in the smallest frame (e.g. v8 in s-10) or not happy with results. Like the guy who spends 30k upgrading a honda civic and it will never be faster than a corvette when it would have been cheaper to just save then buy the used 30k corvette. I need about 4 different cars depending on my moods for fast, or off-roading or even a convertable but I'm poor so the tacoma was the best choice with all the options. So before you get jaded with the truck; fix it, keep it, then go buy the fast sleeper car/truck you want. Good Luck

 

well coming from someone with a 3.4L, i couldnt agree more. I think its a huge waste, tuning is a nightmare. An absolute nightmare compared to tuning a GM/Ford vehicle... especially at sea level. I should have done an ls1 swap right off the bat or bought the 2.7L and turbo'd the crap out of it lol. So you arent the only one who spend 4k on a s/c and was a little disappointed.

 

Sorry I have been gone so long. I started this thing all wrong. It should have been "just in my opinion". Some have PM'd me about cams and pistons. My brother and I design and build performance parts and have been since 1984. Mostly for BB Chevy engines, but have dabbled with my Tacoma for the last 2 years and other makes for the last 10 years. I need to clarify that I installed the S/C without any mods and found it a little disappointing. To make things worse, I had a horrible time with TRD customer service in obtaining info and a spare parts list. Still no list and no return calls. We made other mods at a later date. Someone asked me about cams. TTC Performance makes cams for the 1gre. Good luck in getting info from them. We have successfully made cams for my truck and my son's. No warranty of course, but they work great. As promised, I will post some pics we took last year during the process. I will put them on this thread along with some other issues we ran into. I am getting ready to take the S/C apart and will take some pics of the process so everyone can see what it looks like. I damaged the internal threads in the snout while changing pulleys and will have to fix by either replacing the rotor assembly or machining the snout. 4K for 60 horses just does not add up. 4K for a whine that is really not that impressive. 4K that I would have rather put into my youngest son's education.

 

You're right!
I wouldn't have a SC if my kids were young.
I have one left in his last year of college.Our home is paid off.
Time for me to play!
I can afford the SC and maybe that's why I like it so much along with the upgraded performance.

 

This is the key right here, I have built 700HP Twin turbo FOx body mustangs, that broke windshilds when the hooked up. But that required MAF, huge injectors, huge fuel pressures....and would never have gone 250K

I have built 5.9 12V cummins that have but out 600 BHP with huge boost numbers and huge fuel pressures, would have gone a long time but it' was built for that.

When You stuff 10+PSI down the throat of an engine that didn't expect it, you are going to loose that long term relaibility. You will eventually have blow by, you will have fuel issues, not saying that it won't work, and might go for long, but TRD is still toyota, they aren't looking to make 500RWHP while trading that long term reliablilty that toyota is known for.

Also a 70lb + TQ increase over the spread is def better for DD then a massive 200HP hit at the end. But it depesnds on what you are doing with it.


I had an 02 GSXR 750, that I built for track days, the HP was 177 and Tq in the 140's. But both curves looked like the rocky mountains. in 2nd gear from idle, you could go wide open throttle and you would puts along like something was broken, but @ 4700RPM you had 42RWHP, and 4950 you had 90HP and from 5100 till redline you were above the 150 range.. but on the track i never let it drop below 5000 RPM.


So what i am trying to say is, you get what you build....and TRD build exactly what most people want, a little more power with reliability vs. neck break power, that the drive line as well as the engine wont hold up to

just my .02

 

Great post!
Especially the last paragraph.

 

LOL if you are saying a turbo would be easier to tune then you are WAY off track

 

just saying a turbo 2.7 probably could have made more power for a similar price and got better mpg. But the s/c works well offroad, probably better than a turbo would.

 

I am sorry to hear that the TRD Supercharger has left you wanting more.

It is a very nice system that can be built on for more power and performance.

You did not say what year your truck was, but it does not matter if you have the 3.4 or the 4.0, the URD can help you get the most out of it.

Feel free to give me a call and we can talk over what your goals are and I can recommend you decide what the most cost effective way of getting there.
