I noticed the really flat tq. curve on ths TSX now that some ppl have told me. I guess that's the diff. in feeling I got from it. I know I don't have an ass mounted dyno so I figured the best way to figure out what kind of balls out acceleration was to ask you guys.

Any timeslips with 60', 1/8th, 1/4, and trap times for me to look at? I don't want car and driver or another magazine (I never trust them), I want the real thing.

only one user so far and he didn't have is slips although he is very trustworthy. 15.5 @ 91 all stock including the all season rubber. With better rubber probably a couple tenths will come off that.

Tinky did you see the Auto TSX dyno in the Intake Warranty Thread ?

As Tinky was saying before, I went to the track a little while back and put up that time. Sorry, no scanner. My 60' sucked in my opinion (2.3), and the car was definately in stock condition. I didn't even play with the tire pressure. I also agree that car mags suck at their times. They put up 15.2 in an RSX-S, and I did 14.9. They did 14.1 in an S2000, and I did 13.9. Most of the mags have said that they ran 15.7 in the TSX. I think I need to go work for a couple of these guys. I'm not god behind the wheel, but I've seen better times consistently. I also have the ability to drive around the track (if they need testers for that too)after a couple years of SCCA racing experience (ST1 class and showroom stock in my S2000), and a couple of Bondurant certificates too. Most of the drivers for these mags have more extensive training than even I do.

An ass mounted dyno, eh? Now, that would be accurate!

civic4982

wow nice times. like I said, my ass mounted dyno hasn't been calibrated lately. If they had made this thing a 14 second car out of the box it would truly RAPE all competition. 325s and IS300s would be on their asses.

really the reason the TSX feels slow is because of the tq curve. It should be rated at something like 180lbft @2700rpm 200hp @6800. Torque is more or less peaking up to 5000 rpm then starts a slow fall off to redline. This kind of configuration is good for day to day drivability but is a compromise when it comes to dragstrips....especially considering that the 6mt is geared very aggresively thorugh th first 3 gears. That being said intake mods are showing to be very good...gains of something like 10lbft from 5500-7000 rpms. When coupled with the aggressive gearing that's gonna really pay some dividends at the drag strip. The last thing to remember is the fact that that tsx comes with 47lbs per corner(wheel + tires) That's the same as your cls-6 with a lot less torque. By switching to lighter wheels + tires you can expect some really substantial gains.


EDIT: As an aside most mag times have the tsx within 1-2 tenths of a 325/is300(which very well may be attributed solely to the summer rubber those cars come with), it also has the tsx quicker than the c230, a4, and even saab 9-3arc. Yes that's mag racing so may be somewhat pointless but it at least shows it's competitive in it's segment.(and the cheapest of any of the cars listed there)

you're right about that tq curve. it's flat from the dynos I've seen and hence why it feels slow. Why should it be rated at 180lbfts? You're not making any sense there. It's rated correctly at 166ftlbs @ 4500 RPM even if you think it's faster than that suggests. I don't think the TSX ever sees anything NEAR the 180@2700 you're talking about.

were these magazine times on manual transmission cars or automatic?

that is true about the wheel and tires. but then again once you start modifying a car times shoot down anyways. Wheel weight, gearing, these were things that Acura should have considered and handled before releasing the car.

The fact that the TSX is quicker than an A4/C230 doesn't surprise me. The C230 is a POS, and the A4 is at very modest boost levels. I don't know enough about the Saab to say anything.

from dynos the tsx is putting down like 155lbft of torque to the wheels..even with the auto it's near 150 at the wheels. Torque figures are definitely underrated with this engine just like they were with the k24 in the accord. For example a stock cls auto puts down 185 or so fwtq rated at 232lbft. For a tsx to put down 146(like the one auto dyno we have seen) it should be rated at ~182 lbft at the crank. There is a sticky in the performance sectino if you want to see dynos to backup my claim.

You are definitely correct about wheel/tire weight. I'm sure it's just one of those thigns that gets cut due to cost. Light weight wheels aren't cheap..i'm sure the engineers wanted them but at the same time i'm sure the marketing people demanded 17s and there is always the cost factor they were trying to keep down.
