I just finished installing Kevins Zero Clearance hybrids. It took about 7 hours and feels good to have accomplished it in an evening. The car already ran for its first of about 10 -15 garage heat cycles to break in these ZC's. Looks like I will be setting my alarm to get this thing up and running every four hours to rack up some heat cycles. Kevin G

 

congrats!!

i bet youll get 0 sleep.. haha...

 

very nice... break them kindly... it will go along way....

 

Mark, I do not expect it to even leave the garage for a couple of days. Every 3 or 4 hours I will run it and heat cycle. Kevin

 

Good Idea... I recall Kevin grueling me on my stage 5s... but they worked awesome...

 

Congrats, Kevin.

 

which version did you install?

 

Great news...good luck with the break-in...I followed Kevin's instructions and have 0 oil usage!

 

Stage 2 Hybrid K16/24 but he did a lot of custom work to the hot side. The Zero Clerance option will flow the air on the cold side like there is no tomorrow but a stock k16 hot side runs out of legs around 5K rpm. So he ported and polished the turbine housing and increased its A/R ratio to that of the K24. So it will spool but can still breathe. He has his own ECU programming to take advantage of the ZC option. Plus he is writing me a 500HP low boost program for my wife when she tracks the car. He did not charge me for the 500HP file either. Kevin

 

BTW 4 heat cycles and counting as of 10:30 AM. The neighbors were not too thrilled with me getting up every 3 hours in the night to run the car, but they will get over it. 12 garage cycles and I start the road break-in. This is painful!Kevin

 

Can't the turbo's be heat cycled in an oven before install or do they need to be run in? Sorry for the noob question.

 

Tim , thats not a noob question at all. Kevin runs the turbos on his bench in the shop ,but he cannot create the heat that is produced on the car. With the Zero Clearance option, there is not a lot of room for error with tolerances. So it needs to be run in a very specific manner so the dissimmilar metals with different expansion rates all come to an agreement not to grenade. Basically several 15 minute cycles at idle, then cool. Then more with the RPM up to 2500, then cool. Then 3500 Rpm, then cool. You get the picture. What is happenning is the compressor wheel is etching into the Zero Clerances coatings on the compressor housing. Pretty wild stuff. Kevin

 

Do these work better on a stage II than just switching to K24's? How much do these cost, and where do you purchase them from?

 

Well, they are K16 based so you could do an exchage.They will work much better than stock 24's. Kevin at Ultimate MotorWerks sell them. His # is 1 360 805 9066. As for price, that is between you and him, but I will say that his prices are very competitve. He is more than willing to chat on the phone. Kevin G

 

Thanks for the info!
