Sounds really nice and starts great!
So they trust you to send back the faulty tranny after you removed it? Good service 4sure from Rancho.

Weird thing on the pulley sealing issue on both engines. Curieus to know what that was in the end.

I've got 150-ish miles on the new motor and I noticed the oil leak has gotten smaller as I drive it. I haven't been nice during the break-in and floor it or engine brake where ever I can. If the leak stops on the street motor I know its a good indicator for the race motor, that's the hope anyways.

So I got the tranny swapped out and the motor back in over the last couple days. While the motor was out I took the pulley off and found the source of the leak. I hadn't used enough spacers on the sand seal pulley and it "kissed" the seal spinning it in the housing. It's a press in seal, so I pulled it back out, cleaned it back up, and bonded the seal in place with a thin coating of hondabond. I added a couple more spacers to the crank, put the seal back in and buttoned it all up again.

I discovered the hard way that the big HP1 filter doesn't have enough room to come off with the exhaust in place, so I changed it for a smaller filter. While I was at it I checked and the valve clearances, and re-torqued the heads. I checked the spark plugs since they were easy to reach and the mix looks spot on if not a hair rich.

We took it out for a spirited drive yesterday, and I gave it the beans whenever I could and no oil leaks that I could see. So now I'm going to double check the seal on the race car and I'll probably find a similar situation.

Well if it's not one thing it's another. New motor and tranny are too much fun, dangerously fun, but now the odometer in the speedo gave up the ghost. Apparently it didn't like the quick runs to 90mph so now it doesn't move at all or 10x too fast while the speedo reads just fine.

I also got a chance to refit the new front springs and dropped the overly stiff 300lb/in. for a pair of 200lb/in. Now it feels a lot more stable in the corners and rides a bit smoother in front, however mid corner bumps or aggressively driven banked corners put the tire up into the fender now. I still need to get adjustable front struts but they are being bumped for a set of front tires and an alignment.

Thats interesting as I rather like my 300 lbs springs and don't find them too stiff. Maybe its because I have a little bit more weight on the front axle?

Good to hear your engine works so well now!

Wally, do you know your front corner weights? How much stuff do you have up there? What rear springs/torsion bars are you running?

Not by heart, but 2 years ago it was about 42% at the front, but now with the heavier G50 tranny its probably more like 38-40%.
Total weight with cage is probably around 985-1000 kg in street/track trim with about half a tank of gas, so its about 400 kg front side or 200 kg/450lbs per front wheel side.

I have the DS oil tank up there, oil cooler, fuel pump and filter, hydraulic clutch reservoir, the battery, waterinjection tank, thicker sway bar of course, some bars in the front subframe and some to hold the DS tank in its place and a bar between spring towers welded in.
Plus the usual 4 ltr reserve tank and some spare tools.
All in all, it adds up I suppose and that was the whole idea too

In the back I now run 25.5mm torsion bars only with a Whiteline 24mm swaybar.
