  1. ZCG's numbers show it's certainly no slouch, although I wonder if with some compression and ethanol this would support 400whp+.....
  2. I'm right at the crossroads of what do I do with my L series for time attack/road race use. Swapping for a V8 has appeal, but I just saw the post on Z car garage, and, well. Time to investigate! This is really an incredible project Derek.
  3. 15x7, depending on the offset will be the limiting factor for things like the bumpsteer spacer (too thick and the tie rod will hit the wheel barrel). A quick steer knuckle can help here, since it brings the tie-rod closer to the car centerline, but for a EP/ITS car, I'm not 100% convinced you need fast knuckles. Auto-x, yes, track car, not sure. That bushing looks like a way to adjust the trackwidth/roll center without going to heims, as limited by class rules. Tube arms and heims are tube arms and heims. Go with the ones that tickle your fancy and go from there. I thi
  4. Quite the fleet! We've got a 1987 BMW 325e (AKA Garbage heap), my 1997 12v Ram 2500, a 20' enclosed and my wife's tesla out front. So a similar hodgepodge of junk. The Z lives in a 1946 2 car garage, so a root cellar with a wine nook haha. I'll be sure to post up when I make it down to the Willow area, see if some of you Cali folks want to come make a day of it!
  5. Are you North or South? If North.... Well, you got room for a truck and trailer? Hehe. I know a bunch of the endurance racing guys go down there in march for the season kick off event, and most of the time don't have issues. NIMBY's are clearly the worst, and I think the track has had it's own management issues over the years. Certainly something to look into tho, would be a lot of fun to do a few California trips!
  6. Big Willow/Streets of Willow would be a blast, but 15+ hours towing. Laguna has a lot of cool points, but yes, the sound restrictions do seem goofy. Probably better to do it now before this motor gets swapped out for something louder! Maybe late this year I'll make the trip to Willow, there were a couple friends who made that trip already this year. It would be interesting to see how it stacks up against the late great John Coffey.
  7. Would love to get down to Thunderhill! Didn't realize Sonoma was relatively close, any others worth visiting in the Bay area?
  8. Turn2 Lapping day at the Ridge Motorsport Park up in Shelton Washington. Practice day for the Global Time Attack event happening in late July, where I'll be losing in the Unlimited category haha! I'd like to get into the 1:50 flat territory, and maybe with some bravery and more aggressive shifting I can make it happen. Aero cars can go sub 1:50, but I need more power to get that quick. One day I'll remember to invert the Y axis on my datalogger, but for now, you'll just have to enjoy the backwards version! Thanks Jon!! Getting more confident.
  9. Another weekend, another day at the track!
  10. Marugen Shokai http://home.att.ne.jp/sky/FairladyZ/ Can also get them from RHDJapan: https://www.rhdjapan.com/marugen-shoukai-works-over-fenders-standard-type-s30-s31.html Designed for a front G nose car, so lots of modifications needed to make em fit a standard car with or without an airdam.
  11. Thanks guys! @clarkspeed Daytona sounds like a real trick with the speed differential. Can you opt for a main shaft that you can just barely get rolling off the line, but allows the top speed? I keep thinking about a Winters style quick change, so I don't have to rebuild a couple of rear ends around my diff. I think my ratios are good for my power, and I just need to modify top speed with final drive. Looking at west coast tracks, I think a top speed in the 150's is ideal. much faster you need tons more power, and a 5 or 6 speed to keep the ratios reasonable.
  12. Exedy OEM on a lightweight flywheel is a great choice, Exedy makes good stuff. ClutchMasters makes a good flywheel for our cars, I'd recommend that as well. You don't need extra clamping force with stock + power levels, so no need to go full stage 6 unsprung whatevers. A Tilton 5.5" would be the next best thing, just because it will reduce rotational mass enormously, but it's at the expense of everything else.
  13. Hey Clark! Sorry not sorry Conversion to 18's was a major project. Gearing isn't fully sorted out yet, it was geared short for autox use, so it's not quite ideal for the track yet. Going to 18's gave me a 25.5" tall tire, from a 23.5" tire, so keeping everything the same has moved my top speed out a bit at the expense of low end grunt. I have a 3.90 rear end and a Jerico 4 speed, so I can get fully nutty with the ratios. I'm considering going back to the 3.54 rear end (need to find one) to get some more top speed, but right now being gear limited to 135mph feels just fine by me!
  14. Congrats on a serious score!!
