[QUOTE="zilla8, post: 11008768, member: 105219"] I thought I should come on in and clear a few things up.I'm one of the early KB owners who had the problem with my cats. although the cats failed and contributed to my ultimate engine problem it may not have been the only thing involved. It was not tune related as my dyno tune was pretty conservative and my tuner is one of the best in the country. It's no secret that running cats on a FI car is not the best thing to do if you don't have to run them.I don't want to dwell on my issues as they are behind me now. I had my motor rebuilt with all the good stuff :) Diamond forged pistons 10:1 comp and Manley pro series rods and I also have ARH 1 7/8 longtubes with offroad X and Gibson axleback exhaust. I have around 4K on the new motor and I'm loving life.I'm making 580rwhp at 9# and I may go to 11# but we are limited to 91 octane here in California. I can tell anyone who is considering a blower that this KB 2.8 is a monster and very well built.They are local for me and have been great with customer service and support. I have not been to the track yet with the blower but when I get some numbers I will be sure to post em for you.I hope this helps and don't worry if you have cats just make sure the tune is spot on and not dumping fuel to cool the cats. I had Magnaflow HF cats that failed but I also saw 2 others with stock cats melt on supercharged cars. [/QUOTE]
