Good luck today, post back with your results.

2 runs to go. First 4 short runs went great. On the 3rd pass I let off at the 1000 foot mark and passed the 1/4 mile beams at 10.06 at 127mph, with a 1.60 60 foot. Now for some 9's.

Congrats!

How did the rest of the day go? Was there anything they didn't like about the car or was it a pretty simple process?

:D

My first 4 passes had 1.6 60 foot times. My alternator belt came off on my 4th pass in the morning, so I went and picked another belt up in Eau Claire The temperature outside was 88 degrees by the time I got back, the track was biting hard, but I never raised my 2 step to compensate so the car bogged on both launches. The last two passes went good, both over the 150 MPH mark. Still achieved a 10.006 and 10.041 with high 1.8 sixty foots. Good enough for my license, all you need to do is go faster than 135MPH or quicker 9.99. They had no issues with my car. I found 2 licensed drivers at the track, there were about 5 cars that were running faster than 9.99 so finding licensed drivers to signoff was easy.

My only issue that I have and it sucks is that I’m about 90% sure that my flywheel loosened up on the last pass, I will be removing my engine/trans this week to inspect. I will do everything I can to make it to the MAP weekend with a 100% running car. Anyone have tricks to make sure the flywheel will stay on? I used Red Locktite with ARP bolts and cleaned/degreased the crankshaft and arp bolt threads before installation.

Jim when are you going to get the EVO to the track for a shakedown pass on the new setup?

IIRC JET got so sick of his flywheel bolts coming loose that he actually tac welded them after torquing them. A bit extreme, but I'm sure they'd stay tight after that!

What did you torque the bolts to? I torque factory bolts to 135 ft/lbs with a lot of red locktite.

Good luck I to will be putting my stuff back together and trying again at the MAP event.

Safety wire.

This happened to me once.

My solution was to use a spacer plate (is that what they're called?) from an auto dsm as well as longer arp flywheel bolts from an mr2. And also lots of red loctite.

I saw your transmission carnage, it’s too bad. What sucks is that this is the reality of high powered DSM’s, always one run away from catastrophic failure. The dog box route is crazy expensive, and still problem prone if not operated perfectly. I asked Shep what the cost was about two weeks ago and it was around $7K! He said that he is testing and possibly going to release a 4th gear upgrade for 1G awd’s. I’m keeping track of the number of 4th gear pulls in my car, once it hits around 75 runs through I will be replacing 4th gear proactively.

If I remember correctly I applied 130lb/ft of torque. I spoke to an engineer co worker that deals with vibration and fasteners. He thinks my mistake was that I used oil under the head of the fastener and not locktite. My thought was since we use no washers I wanted to make sure that the torque applied to the fastener was used to compress the flywheel and not fight against friction on the face of the flywheel during the installation process thus not controlling the actual clamping force. Unfortunately that surface should apparently be used as a friction surface after the locktite sets up.

Anybody have a uncut OEM 6-bolt 100mm crank for sale?

Green is good for wicking threads in applications that have fastners preinstalled. I'm going to try red again.

Yea I saw some people wiring the flywheel bolts, I saw a post on NABR talking about. It will definitely stop the flywheel from actually falling off, but unfortunately the bolts can still loosen up. Thanks for the input!

I don't think I would try this quite yet, too many other possible failure modes created by welding.

So did the spacer go on the bolt side of the flywheel? I wonder if it would fit a QM twin flywheel? At least it would act as a large washer.
