Vortech on a 3.4L

[Canyonero]

I'm contemplating installing a Vortech supercharger in place of my A/C compressor which has pretty much never worked anyway. Thoughts? Suggestions? Recommendations? Considerations?

My application is a primarily street driven 4x4, moderate towing and off-road uses. 2.8 to 3.4L engine swap with 3.1L intake, someday might be a straight 3400 or 3.4/3400 hybrid but I kind of doubt I'll do that swap with this truck (though maybe another, I have all the parts).

Currently installing a Crane H260-2 Cam, comp springs, comp 1.6 rockers on a stock 80k mile engine with a high volume oil pump. Also converting to a 1227727 ECU.

I have connections at a local machine shop to get the mounts fabricated. Mounts should be compatible with TBI Troopers as well as other RWD applications.

I say go for it.. If you have the time and ability to do it.. start low boost and work your way up is my only recomendation.

actually it work i did it on a 3.4l dohc lq1. but mines with a procharger

Should work if it fits. Mars has a Rotex CSC in place of his AC on his Cavalier.

What a Trooper does have is a fair amount of vertical clearance, and the left side is less congested anyway. I think it would fit fine. So what are the pros and cons of the different brands?

[IsaacHayes]

Some need oil and coolant, some are self contained and only need coolant. Some might not need any external fluids, not sure.

I have a vortech blower on one of my maxima's. It's V2 S-trim. It has an oil line going into the top of the blower, and a drain back tube on the bottom. Remember with centrifigual blowers you are going to hit peak power at redline unlike a positive displacement bower...just something else to think about.

He is entirely right on that one! You'll get much more advantage out of a positive displacemen blower, for your uses of offroading and towing. The additional power will be avail to you immediately, rather than being concentrated in the upper RPM band.

Something else to consider, an Eaton positive blower, will be internally oiled, so no need to run lines. Some of the newer Eatons approach the thermal-efficiency of of traditional centrifigual's.

If you end up needing more power in the upper RPM's, there are some very tallented individuals out there that can port the SC's housing to accomodate this. Usually with only a small loss on the low-end.

Talking about a "Roots" style? M90 and the like? I was looking at those first, but the installation would be a bit harder. Agreed, probably better for my uses.

[IsaacHayes]

If you can grab an M90 from a thunderbird, those have a neck that you can plumb anywhere you want. They don't discharge into the manifold like the 3800 style ones. They ran an air to air intercooler stock, so you can do the same and plumb it however you like up to the engine.

Yes, I have that Rotrex one, but IMHO a M112 or M90 would be better for high torque requirement such as your truck.

My car under 3500 RPM pulls much like a stock motor, then over 5000 it will light up the tires to 65 MPH on the street, just to give you an idea.
