Mark also ran the Summit COPs for a long time, until his most recent rebuild (or maybe the last one). That was in a period when his car was running too.
XCOPs look very interseting too.

 

I have the accels and no problems with them at all after a couple thousand miles. Cant say there is any gain with them is the SOTP meter but they were only 200 so it wasnt like i was expecting to gain a bunch really.

The XCOPS i have been told are going to be worthwhile.

 

Thanks for the info everybody.

I recall reading a thread on the old forum about you comparing them zkiller , thanks for chiming in and I think you are right your the only person I have seen who has tried more then one set.

Where can I get a look at these xcops?

 

i think these might be the xcops?

What exactly is spark blowout? How do you tell if your cars got it? Is it only pertainable to F/I cars?
