Yeah but a surprising number of folks see the leading 0 and get put off, without consideration to the number that comes immediately after, and Pennsylvania's climate can be pretty rough up north.

Be aware that the first number isn't the boogeyman here. It's an indicator of cold weather performance. All else equal, a 0W-40 should have better cold start protection in sub-zero temps than a 10W-30, while also having higher viscosity at operating temps than 10W-30. I don't know what part...

The only reason 5W-30 isn't listed as an option in the US owners manual is CAFE, it's given as an option in the UK CTR owner's manual: 0W-30 is also listed and you'll note that the UK owners manual says not to use 5W-30 if the ambient temperature drops below -30°C, which is -22°F. We usually...

I think there are several ways around this but I heard the same thing. Their kit comes with four low-profile zip ties, so you could put one or two of those on the collar, then the inside-out fabric, then another zip tie on top of that to secure. Could also just wrap some fabric tape. I have...

These are good fluids as well. Castrol SRF's trick is it's unusually high wet boiling point. While you may want to change a fluid like RBF 600 or 660 every 2-3 track days, you can stretch SRF much longer. That factors into your consumable expenses as well as your time investment. I...

Whatever DOT 4 they put in at the dealership is not necessarily representative of all DOT 4, and DOT 5.1 is not necessarily better than all DOT 4 fluids. In general, fluids meant for racing will be DOT 4, not DOT 5.1. DOT 5.1 fluids are about more than just boiling point. The DOT 5.1 spec...

Would it work better with the low power spring that Acuity has for the shifter?

So I plan to drive the ITS throughout the winter and one of the things I want to know with the fluid change is how the OE fluid feels compared to a somewhat higher viscosity fluid like ACDelco 10-4014 or Redline MTL when the temp is hovering around 0°F, as it does around here every year. If it...

So I'm of two minds on that. I think you'll see an improvement in feel with just a flush of clean OE fluid. Getting the gunk out of the fluid from break-in will alter the synchro feel a bit. So when people post and say they switched to X and the shift feel is so much better - some component...

The sarcasm may have been lost in transit. I have been CDV-less for the past 600 miles and enjoying it a lot. Question - do you mind if I quote you in my CDV delete instruction video on your experience? Specifically this: Also, have you given any thought to changing your trans fluid yet...

Worthwhile mod!

Nope, definitely in your head, no human can feel the difference in 37 ms of engagement speed, it takes you 500 ms to shift anyway unless you're Ayrton Senna, studies show human reaction speed is 200+ ms, blah blah did I miss anything? Glad it went well.

Have you or have you not driven a DE5/FL5 with both the CDV and CMC damper removed? That's the only experience I care about. Negative. The total is 31 ms from the initial delay (attributed to the CMC damper) and then once the clutch fork starts moving, it takes 37 ms more time to fully...

You must not have read my post, because I made it pretty clear that you're removing nearly 100 ms of various kinds of delay from the system by deleting both components. 315 ms down to 218 ms. And you're just hypothesizing. I'm telling you my actual experience with it (which you lack) - it...

Don't conflate delay between a commanded shift and an executed shift with the actual shift time (that is, drop in torque output.) It doesn't matter if the car waits 100ms to shift for you if it's executing that shift in the tens of milliseconds. I've seen it claimed that some DSG can do 8ms...

Okay, I want to dive into this and break this down in detail, lest somebody read that and believe it. For reference, I timed a lot of my shifts on track with the GT350 in the 260-300 ms range. I'll use 260 ms since it's seemingly as fast as my mechanical sympathy lets me shift that gearbox...

People conflate reaction time with the ability to perceive short-duration events. The two are unrelated. For proof, watch a video with one frame every 100ms. Humans easily have the ability to perceive events lasting approximately 10ms, despite not being able to react to them in 10ms. It's...

I want to stress that I don't have individual numbers on only CDV deleted and only CMC damper deleted. Just did not have the time or interest in bleeding my clutch system three times instead of once. I'm just interpreting the data based on differences that make sense based on how each device...

WIth 1000fps high-speed video. 30ms does not sound like a lot. But when you're moving rapidly, it will affect you more than you'd think. Give a FPS gamer 30ms of lag and they will have appreciably worse performance. Same thing goes for trying to nail a perfect shift, all of these little...

Based on my data, it seems to delay re-engagement by 30ms.
