On the same width wheel, the 315 might not have much benefit over the 275. That said, I've yet to see a car that didn't benefit in autocross from wider wheels and tires (all other things equal). Light CSP and SSM cars are a good example.
Being able to go inboard with the wheel/tire as you add width is nice. Keeps the car narrow for slaloms.
What are you doing for brake M/C? Power brakes? Steering?
If you have a summary somewhere...you can kindly point me to it :)
In reply to JMcD :
Manual steer, manual brakes. Probably going to source a 2008-ish Impala master, which IIRC is 27mm bore by 36mm stroke and 50/50 split because it's from a diagonal-split car. I will plumb it front-rear so I can run an adjustable prop in the rear. I've done the math. It should stop on a dime, tell you heads or tails, and give back a nickel.
also, one of my "advisors" tested 275 vs 295 vs 315 vs 275 again, all on 9.5" rims, back to back, on rear of C4. More tire was always faster, even on sub-optimal rim width.
Today I was really hung up on finding a combination of OE rotor and caliper that would package inside the Sawblades, since I already have 2 of 4 A7s and 2 drag radials for them. WTF, mate, I've already bought the solution in those C5 rims. I stood and stared a lot, until I finally snapped out of it and wrote some goals on the board. Adrian returned the bike lift and in the course of our BS'ing, he said something along the lines of "just get it done this year. Next year you can aim for perfection."
The list evolved through the day, and by dinner time I had actually gotten a couple things done.
Back at it for a few hours tomorrow.

yes. that's why i waited til he was gone to start down this path. ;-)
Nic is short for Nick. 54" chest, 32" waist, can bench press a house. embarassingly handsome. Thomas of Finland's dream, except raging hetero.

Either way, Adrian is a smart guy.
No, Adrian's just smart enough to know he's not up for something like this, but can throw around a few sage words of wisdom, learned elsewhere!
Seriously, the car is awesome, and it's being built by an enginerd so he's going about it the right way. The potential for this thing is going to be massive. I'm really impressed by the current state.

i'd say that's a pretty loose application of "the right way", but i appreciate it nonetheless.

I agree. Just need to convert potential to kinetic!

i question your standards. ;-) but thanks for the kind words!
Another, much smaller part of Scope Creep Sunday was to make better use of wall space. This rose to #1 on the list because I'm out of rim storage space. So I did this:
Then I started removing accessories from the LT1 to prepare for a serious cleaning. I just didn't want to have to wrangle that gritty greasy leaky mess into and out of MonZora and work around it to make powertrain mounts.
It started off gross. Leaking from crank snout seal, timing cover, valve covers, oil pan gasket, and maybe rear main too. I have everything to do a full reseal including intake, and once you're in that deep it's only a few hours more to do the cam swap, hence the scope creep.
after a good bit of soaking in Gunk and scrubbing with a brass-bristled brush, it still looked terrible:
But after a high-pressure blast at the local coin-op, she's starting to look good:
Unloading post-wash, I had a little mishap.
I think the engine is OK, but Sonoma's tailgate took a beating. No more latchy:
Had to play a little ratchet strap roulette, but got everything sorted out:
Daughter's room is above garage, and she felt compelled to check on me:
With that out of the way, I pulled the valve covers and was not terribly disappointed at what I found. This engine has 206k on her:
then I pulled all the intake bolts but decided to stop for the night, instead of unleashing the smell of 25 year old crankcase under my loving daughter's room. I'll pull the intake tomorrow when i can keep the door open.
Don't like the mishap but definitely love the exchange with your daughter. A good chuckle for my morning.

Daughter calls you "Sir"?
that title is rarely used, and only for added sarcasm, definitely not out of respect LOL. it started shortly after she got a job working the counter in a pie shop.
