Manual ZR1 Stage 3X Katech Build
 
My 900 mile "Manual" ZR1 was delivered on (12-23-19) and were hoping for 800-850ish whp on 93.
I will keep you all posted as the build progresses and follow along as we take it to the drag strip to see what a "manual" ZR1 can do with some mods.

Sounds exciting! How long did they say they will need your car for? What is included in their stage 3 package?

LOL
Well I dropped it off 2 days before Christmas so naturally the two holiday weeks were a wash and most of the guys were out so I'm not exactly sure how long they will need it. Jason did say they baselline dynoed my car last week and said it made 638-640

-katech Air intake system upgrades for 112mm throttle body
-Katech CNC ported supercharger
-Katech 112mm throttle body and adapter
-Katech camshaft and valvetrain
-Katech C5-R timing chain
-Katech CNC ported heads, CNC ported chambers, competition valve job, hand blending
-Griptec supercharger pulley and hub

-Kooks Off-road x-pipe
-Katech spark plug wire boots
-Katech 160F thermostat
-Brisk spark plugs
-PCM licensing and unlocking

Added Items so far: ATI Damper & Pulley, Camshaft Validation (I requested an upgraded camshaft that must be validated)

oh lord that will be nasty! Their website doesn’t list pricing (last time I looked) for st.3....pm approx cost if you want to. No biggie if you want to keep that to yourself.

Jason did not given me a real number yet because there are several things I am requesting that may need additional parts/labor and they are not certain how these additions will fit into the build since I also want to stay on 93 pump gas. But I will gladly share that with anyone once I get it.

Oh well maybe except for the Supra video!!
Come on man, seriously......The Supra sounds better than a GrandSport?
LOL

That would be awesome! I'd love to do that. I appreciate the kind words, my friend.

The Supra in that test only won because it revved higher in neutral/park. If the Vette could have revved higher it wouldn't even have been a contest.

What is a “validated” cam?

Every camshaft we sell gets validated on our Spintron valvetrain dynamics test cell. This ensures that the valvetrain is stable and durable. The Spintron is basically a 150hp electric motor that drives a "buck" - a block with a hole cut in the side, dummy crank, no pistons or connecting rods, just valvetrain. We point a laser at the valves and plot their movement out on a computer. We look at the valve movement a various rpm to determine if the valves are bouncing upon closing, or the lifter is lofting over the nose of the cam. We can also run 24 hour Le Mans durability simulations.

Baseline went as expected:

Jason, did you scan these baselines so that we know if there was full timing or any KR?

Jason posted this on his FB yesterday ;/

>>>Today Katech laid off both myself (the Director of Aftermarket Operations) and Kevin Pranger, Director of Motorsports. Together Kevin and I had a combined 50 years of experience at Katech. Kevin managed the legendary Corvette C5-R and C6.R engine programs since inception. Kevin and I, along with former president Caleb Newman launched the Katech Performance division to what it is today which is now over 50% of the company. We are both stunned by the news and there is a lot more to this story that will play out in the coming days. We are not exactly sure what is happening, but major changes seem to be right around the corner. Katech cannot begin to fathom what they lost today.

Kevin is incredibly talented and a wealth of knowledge. I'm sure he'll get swooped up quickly.

While it is a major page turn and a sad end to a chapter, there is a portion of me that is relieved and excited to pursue my interests independently with Harding Motorsports as well as at M1 Concourse. I'm also incredibly thankful to have my supportive wife, Concetta, by my side and encouraging my business endeavors.>>>>

Very sad news...........................

Yes this is very sad news. I assume that since my car is sitting in their shop I got an e-mail from the president (or new president...I'm not sure) yesterday that Jason and Kevin would no longer be with the company and that the company has some restructuring changes going on. Well to be perfectly honest, the main reason I chose Katech over the other great shops is because I have followed Jason for so many years, I trust him, I trust he would oversee my build, I trust he would stand behind his word and make sure I was fully satisfied.

I have a phone meeting scheduled next week with Katech to discuss my build since I am now extremely concerned. The president assures me that there is no change with the engineers or techs who will be working on my car.

Well to be perfectly honest, the main reason I chose Katech over the other great shops who I seems to have more experience with the ZR1. But I chose Katech because I have followed Jason for so many years, I trust him, I trust he would oversee my build, I trust he would stand behind his word and make sure I was fully satisfied.

I have tried to reach out to Jason through e-mail because I don't have his personal cell number but have not been able to reach him. If anyone knows him and speaks to him please have him call me or message me or please PM me a way I can reach him.

I have a phone meeting scheduled next week with Katech to discuss my build since I am now extremely concerned and not even sure I want them to work on my car without Jason being there and during a time the company decides to reorganize and or make changes . The president assures me that there is no change with the engineers or techs who will be working on my car, but my concern is just how focused will these guys be when the company is making changes, going through this transition and have just lost 2 of the main faces of the company?

My car has been at Katech since 12-23-19 an nothing has been done to my car except for the baseline dyno pull last week.
If Joe or NicD @Cordes or Steven@LMR would be willing to get my car picked up and shipped to their shop, please reach out to me. I may be very interested in having them rather do this build. I will know for sure after my conference call next week.

If any of you guys have first hand experience with Katech, (can they still do quality work without Jason & Kevin) or my other top picks were LMR or Cordes, offer up any tips, advice or suggestions please.
Please no advice from folks who have no personal experience with these shops.

Thank you in advance.

Man. I am sorry to hear this. I was quite a fan of Jason as well. He seems knowledgeable and is great in the YouTube videos. I wonder what's going on over there.

Yeah, this makes me feel like the wheels fell off my wagon!

Give us a call mon and I can help you out. Sorry to hear as I'm sure any kink in a build plan is never fun.

Sorry to hear about this. I met Jason a few months ago when I dropped off my C6Z for their Stage 2 pkg. I had been corresponding with him by phone and email prior to choosing Katech. I may go elsewhere with future mods.
