Please correct me if I’m wrong. I was looking into TRD Vortech Supercharger to find out the max specs for the S/C. The information about the specs that I found are down below. tell me if this is true or not. the


Fits engines up to 475 horsepower
Maximum airflow: 700 CFM
Maximum boost pressure: 20 PSI
Absolute maximum impeller speed: 60,000 RPM
Adiabatic efficiency: 76%


here is the link where I got the information

If this is true. What is holding the S/C back? So far IceNine and I are saying impeller, shaft, and the pulley. I will like to know if anyone else have an idea what is holding the S/C back and how we can improve our performance.

 

I wonder how small the pulley has to be to see 20 PSI?

Some are saying 14.5 PSI is the max your going to get out of it. Dunno. Good thread/question though.

 

a 20 psi pulley would hafta be the size of a bottle cap

 

That is what I'm thinking. and you have to get the right belt for it also.

 

Do you know anyone who is running 14.5 PSI? If so what have they say about it? Did they have to do anything to the motor to handle the 14.5 PSI or was it stock

 

It would be a small pulley but also probably better blower blades.

 

Do you think TRD is ever going to make any upgrade parts for the S/C

 

nope

 

that sux. why are they not going to make upgrades

 

It's 31 pages long, so your a little late, but KytC has a 14.5 PSI pulley. He has not installed it yet, but he is running a 12 PSI pulley right now. Don't know why he didn't install the 14.5 PSI pulley, and don't know when either.

TRD isn't going to make any ugprades because they would all need to go through CARB, which cost a boatload of money. That's why it took the original TRD Supercharger so bloody long to come out in the first place. It's also why it's going to take a long time for the 07 superchargers to come out. That, and the fact that Toyota will be honoring warranty claims with the supercharger.

If TRD/Toyota was not concerned about CARB emissions or factory warranty issues, then the original supercharger would've included an intercooler, an upgraded turbine, and options for smaller pullies.

 

That will be nice if did come with those feature after all people spend enough money on it

 

3,000 is bloody cheap for a complete forced induction kit that's emissions legal and allows you to keep your factory warranty.

 

+ another $1-$2k to make it decently fast.

 

The reason we see the 14psi max is because their "special extended pulley drive system"

 

meh. I don't think 'fast' was the reason behind the development of the supercharger.

If 'fast' was the goal, then it would've been around 4-5,000 and given us about 230-250 to the wheels. It's most certainly possible, especially with Vortech involved, but it just wasn't done.

 

So, what's the point in spending that much money? Never seen a "real" answer to that question. And if you say warranty, I'll.... Because 8 out of ever 10 S/C'er owners upgrade the pulley, and immediately void the warranty.

 

I bought mine because I was rather intimidated by turbocharging setups. None of the manufacturer's shops were within a distance I would be willing to travel to get things done. Pay to play has a limit when it comes to shipping my car across the country :p

ZPI is in Kentucky, Sound Performance in Illinois, Turbonetics in California, Greddy...well I don't know where the hell they are, but you get the idea.

I do believe that the main marketing point for the TRD Supercharger is 'set it and forget it' power with full factory warranty. Not every scion owner posts on this board or ystc or whatever other messageboard.

 

True, but let me ask you this question.

Would you be a turbo guy or a supercharger guy if geography was not an issue for you?



PS...you said warranty...

 

if geography wasn't an issue? turbo, but conservatively tuned until I found a beater truck I could use if soemthing should occur.


Although I must admit I really...really enjoy the modded TRD unit. I've heard turbo cars before but I <3 the supercharger whine more :p
