Upgraded CT26 Info

[brad92t]

as far as i know he still doesn't have the equipment to port out turbos for a bigger wheel.. he can do everything else though

of course i may just be making this post to hear myself talk and i should just wait for him to say something accurate

What would be the cost for an upgraded BB ct26 to say, 60-1 trim ?

 

[jtamulis]

We orginally wanted to get a lathe to port the turbos, I had a bunch of parts
to do the rebuilds, and he was going to do all the work for free to add that
cash to what we had to get the lathe. The group buy didn't go through, so he
didn't get the lathe, but we're working with a machine shop to make housings.
so we'll be able to offer them again soon .

As Jeff has stated, I can do upgrades, but right now the only upgrade we do is the 57trim, 56.5mm to4e wheel. This wheel is appropriate for up to 450hp if you have the car tuned and fuel requirements are met.

Yes the BB program is up and running. It is designed to make the turbo last longer. We currently are working on making a ct26 that does not use a thrust washer, but rather the BB controls the thrust.

The thrust washer/bearing is the weak link in a ct26. The nose of the shaft itself measures larger than a to4e small shaft does. The problem is that the thrust bearing/washer is litterally floating in the cartridge. There is really nothing that holds it to the center section such as a spring or a bolt.

When some one runs an upgraded ct26 and has a poor bov or a bov that is not setup right, you explode ct26's.

Around what would an upgrade like that run? Just looking for an estimate or approximation.

whats the stock trim size?

I never thought about this, I'm going to be running 12+ psi on a 60-1 trim with a stock bocsh. you think that flows enough or should I run two just to be safe?

Oh yeah, you'll def want to be getting some brand of recirculated BOV .

What do you mean? Something other than Bosch?

 

[starscream5000]

The STOCK BPV will poop out on you close to 12 psi and an aftermarket bosch will handle a little more than that, maybe 16 psi for a little while too. Something like this is what I was thinking of: http://www.supramania.com/forums/showthread.php?t=39295

Thanks...fixed now.

I haven't updated it yet, but trim of the compressor wheel is (inducer^2)/(exducer^2) * 100

Therefore, the stock CT26 = 46 trim. You could argue and round it to a 47 trim, but whatever - it's small.

 

[starscream5000]

My math sucketh, I'm coming up with 68.386 .

 

[Doward]

square the inducer, divide the square of the exducer, and multiply that by 100

 

[Cya]

what would be the trim of a 67MM compressor wheel on a stock shaft and turbine wheel?

 

[Doward]

Need to know the width of the exducer of the compressor wheel. I assume the 67mm is the size of the inducer.

 

[MDCmotorsports]

And all this math and such - TRIM MEANS NOTHING.
