Anyone here REALLY pushed their cars yet ?
I'm just wondering who here has taken the TSX to it's limits? By that I mean, redlining every gear (well, at least the first 3 gears).
The question comes from something that I've noticed on this past weekend. I wanted to see how the car would do from a straight-line drag-style full throttle run. So, from a stoplight, after redlining 1st, shifted into second, I noticed that I was able to squawk the tires, but the RPMs dropped down 2000 RPMs !!
Originally, I thought it was the way I shifted and maybe I clutched out too soon (possible mis-shift), but after several attempts, it seemed like this was something that CANNOT be stopped. My friend and I even switched the VSA off as we thought maybe it had something to do with the tire traction...but to no avail.
I know the car is not made for drag racing by any means, but could it be the Drive-By-Wire technology that's stopping the car from reaching the full potential of each and every single gear that the driver wishes to impose on the motor?
You guys have any thoughts or stories to back this up with ?

BTW, if you clutch out too soon (without giving the motor the fuel that it needs in the subsequent gears), your RPMs should drop. However, if you DOWNSHIFT and you clutch out too soon, your RPMs will be higher....

Fortunately, I've never had to push my TSX. I once had to push my Accord, after it ran out of gas. But, the engine in the TSX works well and there is no reason to push the car on my own.

I've squeezed every last drop of juice out of my TSX. I'll admit, it doesn't really "FEEL" like its moving but the speedometer needle gets up there pretty quick. At first, I was not at all impressed after experiencing what you did. At redline, you shift, and the car boggs a little, loosing valuble RPMs, then slowly picks up again. It's all due to the gearing ratios. Compared to the RSX-S... shifts from redline drop right into VTEC for the next gear. Again, like everyone says on here, the TSX is NOT a race car. But for a 4 door, 3200lbs, luxary sedan... it hangs with most of the competition. Don't worry... its not your driving techniques, the gearing is a little less aggressive than what most enthusiasts are used to.

What I was referring to with the RPMs was that the earlier you let the clutch out (in an upshift), the less time you spend not accelerating and the higher your final RPM should be. There's also the fact that if you let it out really quick, your final RPM will be dragged up artificially by the clutch action.
On a decent 1-2 shift, I end up at about 5500 RPM in second. This sounds like about what you're experiencing. Maybe you haven't noticed, but there's a big ratio space (1.748) between 1st and 2nd gears. That's why the big RPM dropoff on a 1-2 shift. 3-4 is comparatively less (1.40). Don't forget that fuel cut isn't until about 7400 RPM, so use that to your advantage.

Cool...thanks for the replies. I'm not looking to race this car (i love it too much...I'm gonna baby this MORE than I did to my SiR).
I'm obviously not used to the gearings on this car....the engines and trannies that I used to drag race with were usually, the race-bred sub-2.0L Honda engines (B16A2's, B18C5's)

If, between 1st and second shifts, you powershift your gear change with a quick shift and don't drop the gas, you'll have the tires spinning just enough to keep your rpms at around 6000rpms, where you want to be. The rest of the gearshift are ok if I remember right.
Don't drop the gas, it's gonna kick llike hell, but the car won't die on you.

I've noticed the 1-2 bog too. Its definately the gear ratios. 1st needs to be taller, or 2nd shorter. One or the other. On that same note, i wish my 6th was taller too.

well... I have a 5AT, but I use the sport shift 80 percent of the time I drive... regarding pushing the TSX... well I mostly canyon carve, backroad and mountain runs in my TSX when I got the chance to. I got to say, like any honda, if you keep the RPMs high then it can scream pretty good, I pushed the hell out of my TSX on the backroads a couple of times, its easy with this car, the way the engine and suspension syncs with the driver and the path of the road is unparallel to anything in this class, my buddies 325i can't keep up with me on the backroads with my Trish. I redlined every gear up to 3rd and downshift when my RPMs were too high, and it blinked the number at me and then waited a few seconds after the RPM is at a safe 6K and lets me hold it at the downshift pretty well.
There is no pulling power from this car compared to most I think in the early 1-4K on the Tach, but once it hits you can feel it jump, and then neddle starts flying on the regular traffic or on the freeway.

Pushing it
I don't really drive much over 80mph, so I can't say I've redlined 3rd gear, but I'm fearless when it comes to revving this engine. I've been getting to know Mr. Fuel Cutoff lately. This 6-speed and K24 combination is
and I feel like I'm driving it the way Honda and the driving gods intended.

I drive the $hit out of mine. WHen I redline 1st and 2nd the rpms drop to about 5500 which gives me a huge kick in the ass and I just take off
. I have also redlined 3rd and 4th (not in a row) and I can tell you that redlining these gears is much more satisfying than 1 or 2. The car seems to really open up above 70 mph, just don't be in 6th when it happens and you'll see what I mean.

I haven't, and I hope you aren't. My point: there is VERY LITTLE PERFORMANCE BENEFIT to having 6th close to 5th. There is, however, a substantial economy benefit to having a tall(er) 6th gear (note that the automatic transmission'ed TSX gets better highway mileage than the 6MT--something I've never seen before). That is a fact.

Exactly, and if they were going to have 6th where it is now, then they may as well have raised the ratio on 2-5...this way getting 2nd closer to 1st and being more aggressive all the way through.
With 6th so close to 5th right now we are basically driving a 5 speed. I really think it negates the whole advantage of having 6 gears.

The only reason I can think of for the current ratio is that they were worried about not having enough grunt at low rpm and the driver having to downshift more often. It's like the tranny engineers were expecting an engine with no low-rpm torque or something. Seems to me that the price paid in increased fuel consumption by keeping the rpms up is too high for the supposed benefit.

I think the biggest reason is the cruise control and making sure that the rpms were high enough that it unneccesary to downshift in most situations (since you are stuck in that gear with cruisecontrol on). This is the only reason i can think of, although i still think its a weak reason.

I guess taking my TSX to the track 4 times and running it counts as pushing the car to its limits.![Frown](https://acurazine.com/forums/images/smilies/frown.gif)
I posted the pictures on another forum, but if anyone here wants to see my track pics from October I can post them here.

Right on, just powershift and you won't have to worry about losing RPM's

I apologize if I’m in the wrong forum. Just a quick question: When NOT drag racing, i.e., just driving normally, say in a rush-hour commute, has anyone experienced the revs staying too high in between shifts? I realize that in performance driving you want that, but in ordinary driving I feel that the revs should drop faster than they do. The revs kinda hang up there too long. (My TSX is brand new -- only 600 miles so far -- and it’s not broken in yet.) Has anyone experienced this?

it also might be a honda trick to help match revs between shifts, kinda like an automatic double clutch?

I agree with Clutch and DEVO, the TSX needs a much taller 6th gear. I want to only be pulling about 2500 rpm at 70 mph. That way you get better MPG on the highway. And besides, who minds downshifting for hills (for me it's an excuse to double clutch
)
The top gear test is stupid except for a slushbox.
