Pops and burbles don’t need to happen with a modern street computerized engine. Injector cutoff is instantaneous. It’s added back in to some cars to bring back the overrun sound and when done reasonably, the tiny amount of additional unburned fuel they let pass into the hot exhaust to make...

I really like the burbles that Lotus allows a lot more than my M2C which had a lot of pops and sometimes was a bit much. If you play around with it, there is a throttle sweet spot where you're off the throttle enough to get the burble but not completely off. You can get a looong series of nice...

My pressure switched to BAR randomly a few days ago. Everything else stayed the same. Probably some engineer at Hethel laughing about his random BAR switch generator code he slipped in the program.

No, I think you’ve got it. Outside of the electronics world, analogue typically means something similar or comparable.

I think they are introducing the Fix it Yourself program. Next picture will have the hand holding a socket driver.

I agree the douchebaggery comes from the driver, not the car. So, I have mixed feelings regarding the Corvette. Definitely not the car for me, except maybe a C5, which is a decent track car. Jorts and white leather New Balances aside, the drivers are a pretty harmless bunch. They stick to...

The importance of that sensor lies in it’s strength in it’s ability to sense. And by sense, recognize things that are important that should be sensed.

2500. Only happened once. Never a problem before or after.

I had it happen for the first time this weekend. Started fine at home and then I filled up at the corner gas station before the engine got warm. Fired back up and it immediately died. Started again and it stumbled. Put it in track mode which boosted the revs and solved the problem. After a...

Drove 325 miles on my favorite forest 2-lanes. Put it up covered in bugs and brake dust, but happy.

I guess I do, but it's not analysis, it's just a quick glance at the coolant gauge to see if the car is warmed up. Where I live, before I get to anywhere that would need hard throttle, it's warmed up. On track, yes I do make sure it's warmed up in grid before going full out, even if it means...

Ok, obviously I am a proponent of rev-matching (including heel and toeing while braking), however I do agree it is not necessary. And I apologize if I’ve implied that it is a required skill. The vast majority of people drive their manuals successfully and have never even heard of either one...

Mine has always been fast and smooth. However after my first track weekend i found that shifting close to redline in 3-4-5 required a slower, more deliberate shift. No problem in finding the gear, just didn't want to be rushed into engagement. Maybe it'll become easier after the synchro's...

Rev matching and heel/toeing IS a natural part of my normal driving. No "urgent" or "fast" modifiers needed. And yes, anyone can abuse a clutch and it certainly happens but why tolerate it if not required. I like the way I drive and it's suited me well for many years on road and track. You...

In some states coasting in neutral is illegal. Must be something behind having such a law on the books.

I think maybe the point of confusion is that, in my opinion, the upshift impact does not happen the same as downshift. People naturally reduce their RPM during an upshift, and the input side of the transmission is also slowed in a higher gear so there is a closer match in rpm to the 2 plates...

I only use it twice per drive for a total time of about 2 seconds. I can’t imagine it being that much of an irritant or hard to use to take time to complain.

I’m a little confused over your example. Upshift tire chirping is only the result of clutch release speed and amount of throttle. That is, unmatched revs with a lot of power means the tires are forced to spin to adjust. Speed of the shift is irrelevant. The point of downshift rev matching...

We'll have to agree to disagree on what a cold engine is for full throttle. 170 coolant is only about 100 oil temp in a V6. I like to see coolant above 190 for at least a couple of minutes to make sure the oil is at least 150. Ideally I'd like to see oil above 175 for hard driving. Tomato...

If I were an engine, I wouldn't want to be run at full throttle when cold either. Maybe the ECU is trying to tell you something.

Track mode turns the standard ESC off and introduces a new program thats called track ESC. I think it’s like my M2Cs MDM mode that only intervenes when it senses certain disaster. Great for the street but still too much for the track. It’s probably a little helpful at first, but as soon as...

I'll raise my hand. It's happened many times. Everytime the light turns green as I'm slowing for a stop and I want to keep moving. Also has saved my butt a few times when a car/truck behind is clearly not going to be able to stop and I give it the beans to give us both a chance to avoid a...

Letting off throttle and dropping rpms between gear changes on an upshift is just normal procedure you learn when learning to drive a manual. You roll back on the throttle smoothly as you let the clutch back out to prevent that shock and save the clutch. Downshifting is a different animal...

A Lotus in it's natural environment.

Update from Day 2. Most of my comments remain the same. HOWEVER I had a lot more opportunity to test different things since there were only 4 novices in the green group Sunday and they didn't need instructors. Talk about a wide open track! I did go ahead and bring the car up to it's limits...

I ran instructor sessions with the novice group today, mostly circulating among the novices to provide lead/follow or watch their lines, so most of today's track driving wasn't pushing super hard. However, I did have the opportunity in the last session to just have some fun and see what the...

I'll be running for the first time with ESC totally off, so I'm sure it will at least be able to spin!

Goodyears. I won't be setting any personal bests! lol

Understeer is literally for the masses. Pretty much every make/model comes from the factory dialed in to understeer. It the safest setup since it self corrects as speed drops. It's also the most boring setup since it's much harder to go fast if you can't easily rotate the car in a corner. I...

Nice video! As I mentioned above, the carousels and sweepers can give interesting options like the double apex shown with some of Schumacher's lines. Tire management has become so important with today's compounds. You see a lot more neutral handling to prevent premature wear, unlike...

In a late apex, you've completed a lot of your rotation early so you can actually begin to roll on the throttle (never coast) the moment you begin to unwind the wheel. As you unwind through track out, you are continuing to gain speed so you are hitting the max possible speeds continuously until...

I've never heard of V-ing the turn, but it sounds like basic late apexing a turn. The way to go fast around the track is to maximize your available straight so you can maximize your time on full throttle. Brake deep and get slowed down, turn early so you can start accelerating and unwind the...

So true. I love the silver on my Nimbus, but don't wash it very much. Between the bugs and dust, it gets rough after a few drives. I wish I'd gone black to just to cover my sins. I just touched it with a wet rag to see how bad it was. Pretty bad.

It's just practice you'll get it after a while. When I was learning it, my fun car was a Miata and I had a manual Jeep Cherokee with an I4 for my daily. I used heel and toe with that crappy old Cherokee every day with every shift to get it right and it became so natural that I haven't really...

Just keep the RPMs high. Blipping if you're lugging around at 2-2.5k is more difficult in this car because the engine spins up really quickly and you rev too high to be smooth. Do your downshifts at a higher rpm 3.5-4k and when you blip the engine it won't rev as much. It's really all...

Thanks, those are great pics. The reason I asked is that you will reduce pumping loss of the supercharger by any reduction of restriction (either turbulent air or filter obstruction). If I choose to go this way, I would want to be very comfortable that the Eventuri filter still provides a high...

I was skeptical of the claims, but your independent dyno pulls back it up. Does anyone have knowledge of how much gain is based on the design of the intake vs. reduced restriction of their chosen filter material?

Agreed. The harder/faster you go the better it drives. There also seems to be a car-to-car variance in shifting quality. Mine is light and bolt action accurate and when pushing the car it's lightning fast. Other people seem to have a harder time with the gears. I wonder if it's just luck...
