LOL, 1 year anniversary of the thread is on Monday. The 2 year anniversary of the engine failure is in November. My goal is to have it running before November. I think it's doable given what remains. I had one good workday this weekend. A few more of those and it should be ready.

Everyone has me worried with all of the gremlins that have cropped up on their builds this year. I hope this thing fires up and goes without issue.

Good luck with that!!

With your attention to detail Ben, you have nothing to worry about.

Turbo-Geist

Thanks, Del.

I made the final parts order on Friday. I'm keeping everything updated in this post: https://www.corvetteforum.com/forums...post1590200170

Goal is for 1st startup 2nd week in September or sooner.

Whats your thought on the clutch? I'm thinking that RXT might hold on low boost on this monster. I really wish they would crank up the pressure plate on them as the feel so light anyway. Good luck

I thought they were using a V6 camaro pressure plate?

Turbo-Geist

I've talked to them and seems like it is rated for a max of 1000 ft-lbs. I'm planning to start off tuning on the waste gate springs and hoping to see 10 to 12 psi. I've seen mixed results on whether this is possible with full 3" exhaust and no mufflers. Over the course of a few months I'll slowly increase the power and see where the limit exists. In a way, it's disappointing knowing that I may be doing a clutch job within the year but I've done it a few times and it's not bad. I have a 2nd RXT that needs to be sent in a for a rebuild. I plan to ask them if there is anything they can do to add another 200 ft-lbs to the capability. If they can't increase the holding capacity, I'll have it rebuilt and then sell it.

Any truth to this? It would explain the very light pedal. Seems like a little stiffer pressure plate might be the ticket. Not sure how it would effect the engagement at the track. This clutch was perfect at 800 to 850 rw on bias ply tires with a manual.

I've been told by a reputable source that that is what they use on the RST. I know very little about their lineup, so it may not apply to the RXT (or it may).

Hard to say about the v6 pressure plate. It's a very small plate, almost too small to be from a GM v6, but I can't say for sure. All I know is mine works great.

Ben,


Pat Jerding is running the step up from the RXT in his Camaro. I think they're calling it the street twin although that was the name of the old borg and beck style McLeod. this one is an RXT based one that holds a few hundred more tarks.

Turbo-Geist

Good news Bill. Thanks for the info. How is it working out for him? Have you driven it?

Interested in the RXT upgrade if it exists.

Great work, Ben. Getting so close!! You're going to be just in time to shake out any bugs, and be in prime weather for track

(PS - your a/c line materials came in. Will get them out to you assembled on Monday )

Turbo-Geist

Thank you.
Thanks, Jon. I might miss out on needing a/c this year, but it will be nice to have it in the Texas heat.

The last of the parts showed up yesterday. I need to get working on these plus the other remaining items. I'll probably be building hoses for the trans cooler today.

I sure am liking Red Line D4 in mine. Have tried GM stuff and Amsoil. So far D4 has been the smoothest

Turbo-Geist

Great, I ran the MTL in my MN6. Looking forward to using the D4 in the 6060.

More progress this weekend:

-Transmission cooler and hoses installed



-Made a new bracket for the catch can


-Waste gates installed and reference lines almost complete



-External pump, relay, and hobbs switch complete

Turbo-Geist

I disassembled the waste gates to remove a few shims. It looks like the driver side had a little corrosion inside. This is the same side of the engine that experienced failure, but I'm not sure what would have caused any liquid to enter this portion of the WG. I cleaned it up and pressurized the bottom port to verify function. It stroked fine and the diaphragm held pressure.




-Passenger side for comparison, shown with 2 shims for now (5 shims on the last setup).

had to take another look at that mount, looked like a cast piece.
