Possibly ditching TRD S/C for Rotrex SC

[hybrid2]

Since I have my 1MZ built from bottom up and with boost in mind. I been debating to go turbo or Rotrex. So far I think the Rotrex would be the most realistic decision.

No need to sell my exhaust bits if I go Rotrex. (JP headers and ypipe into 3" mandrel bent piping to fit in MR2 platform.) I don't think anyone would want to pay the price I want for it.

I'll settle with the trd sc for now since it has a fresh oil change on it. but that day will come when I just want more.

I'll let you guys play with the 7psi stuff once I sell this trd sc =P I'm looking forward to more like 15-25 psi kinda stuff

Already have my Vi-pec EMS so not dealing with a litttle SAFC.

This is going into my MR2 btw. 7psi is too little =(



anyways.. I'll TRY to keep the plans and progress posted even though I rarely post here.

Well, you'll have less power down low with the rotrex (centrifugal type) than with the TRD, but since the TRD blows hot air after 7psi and you will be running 15-25psi, I don't think it will matter.

Have you gone checking how to make the bracket to hold it in place? Isn't there a Whipple or TVS that could be made to use the TRD manifold?

i want the sc when you get rid of it

I wouldn't even fool around with superchargers if I had a fully built motor...

[SleeperSolara]

Dang man.
I would say go wit a turbo.

What about a larger eaton blower like a m90? I've thought about that before and Gabe I think is looking into fooling with it. Still get the right now response and a lil bit more efficient up high, plus add some kind of intercooler to the mix.

dont underestimate the rotrex s/c, its not like your normal vortec. S2k guys are hitting 400+ with only 8-9psi. Its efficient and also self lubricated so best of both worlds w/o heating up the oil during DD. With a hot 1mz and allready the normal worry of sludge, hot turbo DD is a thing to consider

If he could get the custom bracket to place use it. That is why I mentioned TVS or Whipple that would have the same placement.

All I know is I wish I could use a rotrex for my car...seems a lot better than the scion tC TRD unit.

[hybrid2]

The rotrex is more if not more responsive than the trd sc and runs a lot cooler. Also can add a A/W intercooler in line to cool the air down even more. Luckily i have a spare 1mz in the garage to do my mock up work.

[sydemoid]

You do know that there are like 3 levels of rotrex chargers right?... lol

I would definitely look into this, I saw that URD makes a kit for the FJ cruiser, and that thing is a beast!..... they got it running I think its 18psi.

If you build it, they will come...

[panic]

The Rotrex does look like it's capable of higher efficiency with lower exit temps than any Eaton, but (as said) the low to mid will suffer for the same maximum boost since TRD/Eaton boost is almost linear with engine speed and centrifugals (ATI, turbo, Paxton) boost at about the square of their driven speed.
However: what have you done to the engine that it's going to live at 25 psi?

[sydemoid]

LMAO

I agree with Panic, 25 psi is no joke!..... can you say blown piston heads?... LMMFAO

Now, I had been bouncing this idea for a while, PtBaller can vouch for that one, I showed him the links a while back.... a 3MZ/1MZ hybrid, with forged internals, and a head spacer (to drop compression), might handle it... however, the question that I have is how is it going to be mounted?

I know the VW crowd has had centrifugal SC's for the VR6 for a loooooong time. http://www.youtube.com/watch?v=pL7MMqMs ... r_embedded

I'm currenty fabricating a TRD style Eaton S/C setup (using a huge M112 charger) for a customer of mine who bought one of my 1mz/3mz hybrid engines. No intercooler on this setup but he is using direct port meth which will do the trick. I love the instant torque of the Eaton s/c's!
