rsx type s feels slow?
My girlfriend has a rsx types with about 100,000 miles on it, there are no check engine lights on it or anything, but it seems slower than normal, it seems like v-tec isnt kicking in, are is v-tec just quiet in this car or what? I know my b16s was loud and easy to tell. If its not working what can I check to get it fixed?

Vtec on these cars are alot smoother than the B series version. Though I can generally tell when mine engages. Maybe get a tune up or an oil change if you haven't already.

The RSX-S has extremely quiet VTEC. As well as the lacking 'surge' of power as it engages. If you floor it you can feel it just a bit but other than that... remember Acura is the luxury brand, they try to make everything smooth and quiet.

alright cool!! I just thought it should feel faster so that was the first thing that came to mind, my stock 91 ls feels like it gets on it more on the bottom than the type s does

Re: rsx type s feels slow? (asilaydying1984)
I had the same feeling and know what you mean. When I felt my brother's '05 RSX Type-S, I was surprised of how it pulled and the sound of the stock motor. I expected so much more from it since it's the future motor, but like others have stated above, it's totally different. The sound of the K-Series has a very quiet tone compared to the loud B-Series we always tend to hear.
The LS feels like it pulls harder than the RSX Type-S because the power and weight of the cars are different. In the LS, you feel like it pulls harder because it has a light chassis where the motor can move it while the RSX Type-S, on the other hand, has a heavy chassis where the motor is struggling and trying hard to move it. Line up both cars together, the RSX Type-S will still become victorious in the end of the race. It may not seem loud and feel like it has torque, but it's the one doing all of the work.
People usually get confused and decide how fast a car is just by the sound it makes. It has nothing to do with that.
It has to do with the numbers the car is pushing down (i.e. horsepower and torque).

have you weighed both cars? the DC5 is not much heavier than your average DC4, stock vs. stock. we're only talking about <150lb difference. the LS feels faster not because it's a tad lighter, but because its peak torque is at a lower engine speed. the "butt dyno" tells you that the car is starting to come into its power at about the exact same time that the torque curve stops rising and starts falling off. for the LS, this happens at about 5000rpm. for the Type-S, it doesn't really fall off appreciably until just before redline, so your butt doesn't feel like it ever came into its powerband. but it did. blame it on all the nifty technologies, like variable valve timing, cam phasing, and i think the Type-S still gets a dual-plane intake manifold, but as i don't own one [yet] and i'm not a Honda person any more i don't read and do enough Honda stuff any more to know.
i'll give you an example. my old SR20DET felt fast. boost built until about 3300-3500rpm, depending on which gear it was in, and of course torque shot up until then. it climbed a bit and then flat on its face by about 6500, well short of its 7400rpm redline. by comparison, my LS1 literally has a torque line from less than 1500rpm to 5000rpm, falls a little by 5500, and then starts a noticeable fall until redline at 6000rpm. the LS1 feels kinda slow in the butt dyno. the car is now quite a bit lighter than it was with the SR, not because of the drivetrain, but i've removed a lot more stuff since then. but the car still feels slow, although you know it isn't slower when you're watching the tachometer needle skip a little now and then because even in fourth gear the needle moves faster than it was designed to.
interestingly, weight of the vehicle has no effect on your body's perception of acceleration. i drove a Ford F-750 dump truck a couple times at work because i thought it would be fun. even with this massive truck and some 10 tons of dirt in the back, the thick torque of its big turbo diesel planted me harder into the seat than any other vehicle i've ever been in, including airplanes and race cars. then i looked at the speedo, and it was moving about 1mph increase per second, so it took a full minute to get to 60mph. slow as heck, but your body senses actual thrust, not the resultant acceleration.
SUMMARY: it's about power delivery (shape of your torque curve), not peak numbers. also, weight has nothing to do with what you feel when driving (unless you're too fat or skinny for the seat you're in and you get pushed around a lot
).

Which Morongo do you speak of? Is it the one near Riverside/Moreno Valley (15 minutes away)?

im sure its working..but like people said the rsx is a luxurious(spelling?) car..so it wont be like other cars for example an s2000.those are built more like a sports car so they will be louder..the newer models of the dc5 transittion are smoother than the 02-04 models..and the same with the v-teck

no Im not talking about casino morongo, I am talking about the morongo on highway 62 north of Palm Springs.

The guy talking about a dump truck feeling fast. I completely agree with him. When I was a valet a long time ago. Diesel powered trucks felt fast, but were not going anywhere.

Re:
Has the 02 sensor been changed?
Just recently changed the one on my 96 Accord about 115k miles and it feel so much different (better), it is an LX so no vtec but still.
And the check engine light wasn't even on beforehand.
RSX could be different, I just figured the CEL would be on if it wasn't running right because of 02 sensor but you never know.

Re: rsx type s feels slow? (jadugartir)
you know, something that you may not have thought about is the fact that it does have over 100,000 miles on it. i would do a compression test on each cylinder to make sure the piston rings are still sealing good and the possiblity of valve float or valve seals may be leaking. check for blue-ish colored smoke from the exhaust, that will tell you if its burning oil. or it may be something as simple as the iVTEC solenoid may be malfunctioning, but it should throw a CEL (check engine light)
if the compression test is good and theres no smoke from the exhaust, then take a few basic steps.
1-new spark plugs irridiums are nice
2-oil change use full synthetic if your budget allows
3-have the dealer or a local shop read the engine codes, reflash if neccessary, or pull the ECU fuse out for 15 seconds and re-install
4-check both O2 sensors for carbon build up, they may be sending the ECU a 'lean' signal which make the ECU correct by adding fuel, which would actually make the car run rich which would rob horse power
5-install a cold air intake, the factory air box is pretty restrictive and has resonators to make the intake sound quiet ( it is an 'acura')
even though the DC5 is heavier, and the engine is more refined, you should still be able to sense and hear and feel when iVTEC is engaged. its not going to push yer eyes into the back of your head, but you should still feel it. and FYI, the iVTEC set point on the stock rsx-s is 5800rpm. so if you do all this and theres still no sense of vtec, then i dont know bro. lol good luck.
