A 12.5" would be more than adequate for a vitour 345.

Possibly but I doubt you're still getting that under a stock S550 front or rear fender.

I’ve seen 345s under an S550 rear fender but they definitely were not on a properly wide wheel. The 18x12” I run for the 315 A052 is tight at the shock top mount but theres a little room at the fender still, so I suppose you could go wider.

New Falken (which I think Kyle K. liked in the previous iteration) is better than old one enough to change pax for SSC and CSX so that might be an option - it used to have 315 19" option - didn't it ?

Yea a competitor ran a 315/30-19 on an 11" wheel against me back when I was trying the Khumo V730.

I meant the new new Falken 660+ which has just been released, new version of 660 (not 660 vs 615). It triggered pax adjustment for spec classes using it after those few events this year.
Don't think it'll have speed of the Yoks/ Stones but might be close.

Yea i was just referring to the fact that he had the old 660 in 315/30-19 but not sure if the new species is available in that size yet.

In person, falken said the compound didn't change. Which is that tires biggest issue. It heat cycles out long before the tread was gone. IMO, I felt like 8 heat cycles, or less, and it was toast for any serious AutoX use. And I almost never see the 660 (old) on track.

On their site, falken is deliberately vague about whether or not the compound changed. So my guess is it's probably fast initially.

Two friends are running them now, so I'm looking forward to their feedback here in a few events time.

The 350 front will definitely fit a 345. The rear, I think you might need to roll the fender. The 325 on mine is very tight.

 

[mavisky]

Relevant to the discussion LOL.

 

[NightmareMoon]

Well thr 660+ is listed on Tire Rack’s site in 315/30R19, but I’m not going to be the first.

Got a fresh fuel pump/ bucket in the car and its like a different animal.

But my fuel pressure gauge is acting funny. Its not zeroing right and like a broken clock its only right about once a day, lol

Maybe we can make the texas tour after all?

On tip in it seems to dip maybe [edit] more than 10psi? but seems to hold better under load than before.

Im not sure cause like I said the brand new gauge needs to go back for repair, but the occasional time it zeros I can probably get some data. Anyway thats a lot better than dropping to 20, but it feels stronger, and seems way more fuel rich if only from the exhause noises. I’ll datalog later tonight or in the morning and take a look at where the fuel trims are at and send it all back to the tuner.

 

[NightmareMoon]

I really suspect now that this fuel assembly was in slow failure for a long time. I went from fuel starving at 1/4 tank to starving on course at 3/4 tank at nats. Its possible this gen didnt like running sitting in E85 or it could just be age+ mileage.

Anyway it was a tough weekend for life so I’m glad to get a small win.

 

[mavisky]

I never like letting E85 sit for too long. Over the winter I always switch to 93 and if events sre a month away I try to drive the car in between some just to move it around.

 

[WItoTX]

Are you pulling data directly from canbus or some other method? I forget, did you do a dual pump set up like the stock 350s?
