IIRC the Accord Sport wheels are something like 31lb and the TLX A-Spec wheels are 33lb, so I'd expect the optional 19s to also be right around there (i.e. pretty damn heavy).
Of course, I couldn't help myself and went ahead and flashed a new tune to see how the canned KTuner starter tunes are. Did a few pulls with the 23psi tune, and my butt dyno can believe about a 50-60WTQ gain in the midrange. The car pulls considerably harder now between 3000-4500ish RPMs...
A couple BF purchases arrived today
Will have the tires mounted this week, and can then play around with the various KTuner maps and see if I get the same gains they get on a (virtual) dyno. The on-the-fly map switching should make running through the various maps a piece of cake.
I finally passed the 600 mile mark, so I took the car out on some backroads that I'm intimately familiar with to put it through its paces and see how it performs when pushed harder. By no means is this 10/10ths driving; I don't even go 10/10ths at the track, but I would say solidly 7/10ths on...
+45
One thing I'll add; even though these wheels are half an inch wider and stick out a little, there's considerably more wind and road noise coming from these tires, even on city streets. I'm not sure what kind of insulation Honda used to address road noise, but it sure seems like they didn't...
Got tired of the stock all-seasons so I put on a spare set of BBS SRs that I had lying around to see if they'll fit. They're 19x8.5 and currently have 245/40R19 tires on them, which are a bit taller than stock. They've got maybe 5% tread left at best, so I have a set of S-04PPs on order in...
What kind of phone do you have? When I played around with it in an iPhone X the times were off by about half a second in the quarter mile (tested against the time slips at Sonoma Raceway). My Dragy on the other hand was within 0.1s on every run and 1mph in the trap, and half the time they were...
Are you using any sort of GPS box to get your numbers, or are you hand timing it using a datalogger or the speedo? If it’s the latter I would highly recommend in getting a Dragy or RaceBox because those are much much more accurate and reliable. They also evaluate slope and track temperature...
If you just want to get a sense of what the power is, 40-75mph with a running start is a good standard. That eliminates drive-dependent variables like the launch (since you get a running start), eliminates the effect of turbo lag (since you get a running start), and there's only 1 shift in there...
