how does VTEC feel on the cl-s 6speed? do u feel it? or no?...and when does it kick in? thanks

ghost_masterCL

It's almost as big a boost as using the NAAAAAWWWWZZZZ.

lazybuttalex

lol..wht i mean is...ok..example the integra gsr...the vtec..yo feel it.....say to...compared to teh single cam vtec..u dont feel anyhting

Is your actuator busted? Without, it seems like your car loses 60hp and doesn't have the vtec "kick."

spdy0001

Well my actuator is working fine, and in my 6spd I can really hear the v-tec engage, but there is no "kick" in power. I laugh everytime I hear that. I love the technology of these engines, but v-tec can't be compared to nos or other power boosters

GreenMonster

There really isn't a kick, but the engine does sound noticably different... There is a noticabe difference in the power while running thru 5-7K rpms.... the car just seems to run along pretty normally under 5K rpm's, but once you hit the camming switchover, it really starts to scream (and the power "surges")...

When I'm in traffic on the highway, it's kinda cool to run @5K rpm or so in second, and once the road opens up, rev it to redline and then into 3rd...

EDIT: the CLS has a pretty decent torque curve (for a ulev V6) from 3K on up, so you won't get as much as a kick as you will from a low end torque lacking 4 banger

EDIT #2: I'm still stock, with a K&N drop in air filter...

superchargedcls

i used to feel a noticable differance with the v-tec but know with the supercharger it is a little differant because i do not feel the vtec kick in just the s/cer

typeR

maybe you just need to drive a more powerful version of the same car....right now i can gently roll into the throttle from a stop reaching WOT around 20 mph, only to have the vtec change over occur and the tires completely light up.

Lord Helmet

I could feel it in my butt dyno on the ex's 6spd. I can feel it on my butt dyno in my autotragic though too.

lazybuttalex

oo k thanks

o1s

there isn't suupposed to be a big power difference. it is just supposed to keep building power.

CL6

Well my CL doesn't really kick at VTEC but it does get louder and I swear I can feel the car surge a tiny bit. Mainly it's when I run it in 3rd up to 80mph merging onto the freeway.

Mikes96TL03CLS

Yeah I'd like to drive a 6-speed CL-S sometime. My bro had an RSX S before he bought his Lex, and that 6-speed was quick.

GreenMonster

And it's pretty sweet too... going from 3K rpms to 5k rpms takes a little bit, but the J32A2 revs quickly from 5-7K rpms...

Some stuff on the J32a2 here:

in stock form the car really doesn't do all that much at VTEC changeover, but with I/H, you will notice that the car pulls harder from 4800 onward to redline.

I had a modded 01 CLS with AEM CAI, and since the VTEC cam profiles are only on the intake side, when it switched over, you talk about a cool sound, it would scare people it'd be so loud.

In comparison, I now have an 01 GSR with Comptech catback exhaust, and since the B series have the VTEC lobes on both the Intake AND the Exhaust cams it's more noticeable in the exhaust note.

Now with stock settings the VTEC changeover in the GSR actually loses a bit of power at changover (can be corrected with VAFC), but once the seconary intake runner opens, it pulls like mad.

CLS powermaking RPMS 4800-7200k
GSR powermaking RPMS (stock settings) 5800-8100.

BlueCLS6

You should feel VTEC + boost... BIG difference. Stab the throttle at 5k+ RPM in 2nd gear and the wheels spinnnnn spin spin ... 'course I'm still on the stock shitchelins

o1s

dude you are talking like vtec was gods greatest creation.

NiteQwill

Who?

GreenMonster

It is, isn't it ?? Best thing since sliced bread

fuzzy02CLS

iTrader: (2)

Completely agree!!

Chemmech

My car will break loose at 35 mph, it downshifts to 2nd and continues to spin the tires half way through 3rd gear, but I'm an automatic.

03 CL TypeS

VTEC on the CLS-6 doesn't create a power surge like on other smaller-displacement Honda's (B16's, B18C's, etc.).

The J32A2 motor obtains it's peak torque as low as 3500rpm and maintains it to 5500rpm, creating strong-feeling midrange acceleration. The VTEC top-end pulls harder of course, but proportionately so.

o1s

i think the sound is misleading to most people. there isn't supposed to be a jump in power. the curve is supposed to be smooth.

NiteQwill

Meh.... I sure feel a kick in power.... but then again...

goredcar

My understanding is that VTEC is RPM related and kicks in around 4500... I had a 5AT before my 6MT and the effect seems to be the same... rush of power and the intake howls...

spdy0001

The changeover occurs at 4800 rpm

Chopsie

You are correct, it SHOULD be smooth, however, when you start modifying things, changes this significantly.

Comparing a CLS w I/H/E to a 05 TL 6 MT stock. At 4800 RPM's (VTEC changeover) the stock TL, you can't really hear or feel anything, the CLS will pull harder. It's not a mini turbo charged feeling like on the S2000, where when it changes over, hold on!

goredcar

I agree with Chopper... it is normally a smooth continuation of acceleration on the CLS... after mods though, you get the combined effect of headers and intake all kicking in at about the same RPM range resulting in a dramatic surge in power.

When my CLS was stock there was a slight pull, but nothing like what I used to get in my Integra. I loved my Integra... great car and I didn't loose a bundle when I sold it, like I did on my previous CLS

MiniDevil

I am pretty sure on my 99 CL 3.0, with 4 speed auto, that the VTEC engages at 3800rpm. There is a significant noise change in the engine, and also a kick to it. It is not exactly 'smooth'... I feel a jolt sometimes and the car surges forward a little, and the front end raises up. The RPM does however begin to go up faster and faster. Not really sure about the other aspects of it, but I do know with the pedal floored from a stop, I feel or hear nothing major until I hit 3800 RPM.

Possibly different on the automatic 3.0s than the 6 speeds...

NSX-Tuner

A fully stock CL-S 6MT will pull a little harder when VTEC kicks in. But a boosted CL-S 6MT will have a lot more kick in VTEC.

All Mine

I didn't think Vattack engauged with the super charger? Isn't that why you disengauge the IMRC when installing the blower?

superchargedcls

i still feel the vtek kick in and i never disconnected the imrc what kind of differance do you feel when you do disconnect it

All Mine

You're supposed to disconnect it when you install the blower. That's what the instructions say, I believe.

NSX-Tuner

From what I understand, there are two parts to VTEC (Variable Valve Timing and Lift Electronic Control):

1) The variable value timing and lift still engage above 4800 RPM, even if the IMRC actuator is disengaged.

2) The IMRC is similar in function to a four barrel carburetor's secondary venturis by letting more air into the intake above a certain RPM.

So on a SC'd CL-S, VTEC still kicks in the variable value timing and lift, even with the IMRC actuator is disengaged.

Allout

Instruction do not tell you to disconnect IMRC.

Some have found disconnecting IMRC relieves some pinging issues when running HBP. IMRC is totally independent of VTEC.

For me VTEC was more noticable w/ Intake and Headers. With SC, VTEC changeover is less noticable. Power delivery is more linear.

I also think the difference in VTEC was comparable between my 2003 TL-S and my 2003 CL-S6 with similar mods.

spdy0001

All mine you never cease to amaze me

As the others have stated the IMRC and VTEC have nothing to do with each other. IMRC opens up way before the VTEC changeover. IMRC opens up a second intake runner for more air, which is what was thought to cause the problems with the supercharger.

NSX-Tuner

Actually, the statement "As the others have stated the IMRC and VTEC have nothing to do with each other." is inaccurate. When the IMRC opens up, the intake air flow is significantly increased. This increased in air flow is fully utilized when VTEC increase the valve open duration and lift. VTEC without the IMRC engaged on a NA car would be much less effective; and I'm sure with a SC'd car power would be lost.

I agree with Allout about the smoother power delivery with the SC from the lower to upper RPMs. But when I had the SC installed, I felt the car pull a bit harder at the cross-over RPM for VTEC.

Pellz

from 5 to 7 on the tach feels like a supercharger, I have a 6-speed with cold air, and you can feel and hear it when it kicks in...not easy to keep the wheels on the ground, it wants to get away from you b/c of the torque steer... I can easily burn 'em thru two and chirp third...

o1s

get better tires.

All Mine

I stand corrected I guess I've been misinformed some where along the lines. I apologize.
