Re: Ken's SLC build thread

I purchased a used set of Kent Moore engine lifting brackets (J-41798) to make installing and removing LS engines easier.

Re: Ken's SLC build thread

Back to the hubs again. Can the speed transducer be removed from the SKF hub and then saved for use by another. I don't need the anti lock brake system.

I'm afraid not Howard. It's not serviceable. You would just cut the wire leads off at the hub.

I know a guy selling brand new SKF X Tracker ZR1 hubs for $275 each if you are interested Howard. They have the active ABS sensors so if you are planning on cutting the wires off these would be a little bit cheaper.

Re: Ken's SLC build thread

To help clear up some confusion. Here is a picture of the adapters needed for the conversion of the SKF X Tracker hubs to fit our uprights. Everything in the picture is included. They are chromoly steel. They cost about $475 shipped

Re: Ken's SLC build thread

Our SLC rear hubs cannot be upgraded. The C4 rear hubs that are used on our cars have a 27 spline axle stub shaft. The C6 Corvette hubs have a slightly different bolt pattern and they take either a 30 spline stub shaft (1997-2008) or a 33 spline stub shaft (2009-2013).

Re: Ken's SLC build thread

Thanks a lot for that! I will certainly need to do a upgrade. The fronts are already showing a bit of play in them after about 200 track miles. Not at the point that would lead to emanate failure, but I would call the owners attention to them if I did the tech inspection and want to see the car the next morning for a two day event.

Ken could you send me a Ph# and time to call for you via PM. I would like to talk a bit more about this. Thanks, Howard

Re: Ken's SLC build thread

Here is a how I build the exhaust elbows:

Start with a good set of flanges. I like to use original flanges if possible. The only way to acquire them is to buy the mating cat pipes off the C6 Z06 Corvettes. I buy them for the catalytic converters as well due to our emission laws in Canada. If that isn't possible then you can buy them in the following link but they won't have the step built into them as original. A pair of them in 3/8" stainless is $152.

12212-1 LS7 MANIFOLD FLANGE

Here is a picture of original flanges. You can see the machined step for the gasket. It squeezes it a precise amount.

Re: Ken's SLC build thread

Next I purchase from Summit Racing a pair of 3" stainless 90 degree mandrel bent pipes.

Stainless Works Individual Mandrel Bends MB90300-H - Free Shipping on Orders Over $99 at Summit Racing

Then I cut the pipes as shown in the following picture. A angle grinder with a thin cut off wheel and a reciprocating saw makes it effortless.



I then plasma cut the radius along the marked line.



The radius for the plasma cut is 4 1/2". I made a card board cutout to aid in drawing it out on on the pipes before all the cutting.

Re: Ken's SLC build thread

The ends can be squeezed slightly in a vise so they fit in the stock flanges. Next is to tack weld everything together.



Once that is accomplished the flat sections need to be fabricated. Trace the openings out on some paper and then transfer the paper cutout to some flat stainless sheet and cut them out.

Re: Ken's SLC build thread

If you want to make them on a budget then the flanges and pipes can be purchased in regular steel instead. Stainless has better heat retention and will hold up longer but if you are going to ceramic coat them then perhaps it's not for you.

The same process can be done if you want to save some weight. Carefully (with a reciprocating saw) cut the flanges off the stock manifolds and then weld the modified pipes directly to the manifolds.



In this case you can recoup some of your cost by dressing up the cut off flanges and selling them. That's what I did.

Re: Ken's SLC build thread

After tacking it all together I have a 5/8" steel plate that I bolt the flange to. This helps prevent it from warping while being welded. It acts as a heat sink as well.



Warping of the flange could allow an exhaust leak which will screw with the oxygen sensor reading.
