So tonight, me and two of my buddies decided to get a little bet going on who would win in a race. Me('03 CL-S 6MT) a G-35 Coupe(Un-Modded) or a brand new '07 TL Type-S(AUTO)

_Anyway, we get on the highway and they both take off. I was shiftin at like 6000 and still couldnt even catch upp!! Each of them had a passenger, and I was driving alone, so I really thought I had them beat. But yeah, I got smokedd!!! I dont know what the problem was, but something wasnt right with my car. The past few weeks it just hasn't felt right. Seems to have lost its pickup and acceleration. I dont think my V-Tec was engaging either, but then again I'm not 100% sure on that. Something was wrong for sure though.

_I also get this weird hissing noise at low RPM when I give it gas, and only when i give it gas, and it only does it in low RPM.(anywhere from 1000-3500) Not sure what it is, comes from right behind the firewall. I'm afraid to take it to acura cuz i dont want to deal with them chargin me all that money if i could fix it myself!!

Any help would be greatly appreciated!


Thanks!!~

 

why are you shifting at 6k? sounds like a bad case of driver error to me. but it is possible to lose to boh.

 

CAI = Hissing !?!?!

 

check the lower elbow pipe that leads into the main CAI box in the engine. Mine had come off once and I had to reattach it. Also just check the connections for the piping for the CAI to ensure that each is tightly sealed.

Another thing, is your filter dirty? When was the last time you cleaned it? It's recommended you clean it every oil change (3750 mi) for optimal performance.

A dirty throttle body can contribute to this as well.

 

Hissing behind the firewall??!?!?!

hole in your header? CAT? or downpipe?

 

yahh... y are you shifting at 6k? an 03' G35 mt stock should be fair game using proper shifting



redline is 6900. limiter at 7100

 

Why the hell are you shifting at 6 grand when racing!!? Seriously, you can bang that thing off the rev limiter all day without a problem. You should have been able to hang. Do you know how to drive a manual or are you scared to drive her like you are supposed to? What gives man?

 

As far as the hissing, is it a whooshing sound? If so, that is normal. Mine did it when bone stock only when under load. If it is a pronounced whistle it could be a bad intake connection. Since you say it is only at low RPM I think it is probably normal and from the exhaust like I said before. Please start shifting at 7000rpm when you want to go fast.

 

im thinkin driver error lol..redline that thiiiing boy! i've beaten g35's with my old AUTO, surly you could do better in the 6-speed! just practice your skills more and you'll get it.

 

It'a a HONDA... Hold On Not Done Accelerating...

You've got to rev the crap out of these motors to get the peak HP out of 'em...

If you don't get over 6K rpm you might as well be driving a CLP

 

oh shit

 

When I bought my used 01 auto CLs the Vtech was not engaging and I was running a 15.1 in the quarter. The Rick Case Acura service guys said all was fine but I should try a throttle body service and injector flush. I took it to a local mechanic and had it done for half the price Acura quoted and it made a dramatic difference. The Vtech began engaging and I was running 14.8's stock.

You can always tell when the IMRC is not engaging there is no turbolike surge at 3 and 5 grand or so.

WOW all the way to 6??? It's a Acura, not a Mustang... Take that baby up to 7100rpms

 

So all you had to do was a flush on your cordless phone and you gained .3 seconds on the quarter???






I figured someone else would have saw that already...

 

Maybe your IMRC (actuator) is bad. Check it out.

 

 

What can I say, it was my first race!!! I never really open her up into those high RPM's cuz I didnt wanna f*ck anything upp or miss a shift! But yea, as far as the hissing/weezing noise is concerned, I'm going to check the intake connections and all my lines/hoses to make sure theyre all on tight. I began to notice the sound right after installing the Strut Brace last summer(1st mod), so I was thinking it could have something to do with that pressing down on a hose/line or maybe even broke one. Could it have anything to do with low fluid levels? i.e. clutch/tranny?

 

I dont know how i missed that LOL... good catch

 

it's possible that your vtec fluid is low... try autozone and get the Nos octane buster and fill up your vtec pump...

Sorry just bustin your balls

 

Hissing could be from a vacuum line...

You said it happened after you put in your strut tower brace, maybe you broke a vacuum line and maybe that is what messing up your speed...

 

I took apart my intake, cleaned the filter re-oiled it and then made sure all lines going to and from it were secure and no leaks. Then I messed around with some lines/hoses and found where they were coming from and checked the connection. Everything was fine and the noise is gone!!!!! I just hope it doesnt come back!

But I'd like to still have my actuator checked out and make sure my Vtec is working properly, and also check the vacuum lines. Where are the main lines located?

 

Did the 07 Type-S spank the G?

 

Yea...bastard...lol =)

 

This is the second time you have trashed a response of mine because I have used Vtech to describe the IMRC engaging. I have seen Vtech used a multitude of times in posts on this site to describe the IMRC kick in.

Please enlighten us as to the proper wording or phrase to utilize......

In answer you your question an FI flush and TB cleaning got my IMRC to engage.

 

vtec not vtech

 

No way you should've been in last place. You're only giving VTEC 1000rpm's to work it's magic instead of 2000rpm's easily. I've beaten 2 G35's from a roll and a dead stop. It should've been you and the TL S all the way. I imagine it would be a pretty nice race...

 

I challenged them both to a race at the track when it re-opens, so hopefully by then my problems are all cleared up and I can show them just what a CL-S is all about!!!!

 

why wouldnt your vtec be engaging. like everyone else said you cant expect to keep up with those cars shifting at 6g's. you had another G left in ya.

anyways whereabouts are you in jersey. damn nice ride for a 18 year old.

 

I don't understand your logic. Don't get me wrong, I have a CL-s, not a 6-speed but I have driven in a 6-speed with mods before. Depending on what year G35 it was, those cars have more torque and more HP, so what would make you think that the G couldn't hang with a non-modified CL-S. Even if he shifted properly, it would have been neck and neck among the 3, there is noway he should have left the G in the dust. A completely false statement.

 

My bad....

 

At best he would've been keeping up, but not winning. But he shouldn't have gotten smoked.

 

VTEC = Variable valve Timing and Electronic lift Control

it is the transition of cam lobes to create more valve lift at higher RPM. I think ours engages at 5200RPM do a search if you want to know more.

IMRC = Intake Manifold Runner Controle

Only on the type S (tl or cl) it opens at 4200RPM to change the acustics of the upper intake manifold utilizing the Helmholtz Resonance effect thus acting to slightly supercharge the intake air charge.

 

actuator engagement at 3800
Vtec engagement at 4800 for type s

BTW this was interesting to me because i dont think my actuator or my vtec is working either. i just feel smooth power all the way to redline. except once when i was in third in ss mode and i pressed the gas and the engine surged like i downshifted but i didnt, vtec? if you solve the problem, tell me!

 

You can manualy turn your thottle cam under the hood or you can have someone sit in the car and rev to 5000rpm. if you dont see teh IMRC flip over it is bbaton roken. it wont throw a CEL code if it is and most mechanics dont know how to check it. My Baton Rouge acura dealer didnt even know it existed and when they researched it they told me it would throw a code or not engage in neutral. I have a six speed '03 and after I repaced it, it does engage in neutral and I never got a code. check it. pm me if you need more help. your vtec will only not engage if you are not moving, your spedometer is not workng or is disconected, or you are in neural on an auto. if you need to talk over teh phone i will be glad to help.

 

How is it completely false? How many G35's have you raced? I never said it couldn't HANG, just that he shouldn't have lost to it. Torque and more HP isn't relevant if you have mods that help even the playing field. Then it's just a driver's race. The 2 G35's that I've raced weren't '06's but I beat them nonetheless and you'll get the same response from other CL owner's that have raced G35's. So I hold true to my statement. He should've left the G35 in the dust, I know I would have...

 

Leaving a g35 in the dust? And from a roll on a highway...

 

(crazy intraweb)

You speak of the G like it was a Civic EX

The G can be a handful, especially from a roll, so please join the rest of us in REALITY.

 

Wow, you guys are killing me. I'm not trying to make it seem like the G35 is so slow it may as well be going in reverse. Just that you shouldn't have been beaten, or beaten as bad as you were. I personally have never lost to a G35 and if you search you'll see that many other CL owners on this board haven't either.
Maybe it's just the driver???

 

Ha, how many G35's have I raced, thats a hilarious statement. You raced 2 and make it seem like no one else has raced as many. For your Info, my sister has a 2005 G35 Coupe and my girlfriend has a 2004 G35X Sedan(AWD version, not as fast). I have driven both many many many times and I have driven a modded 6 speed CL-S and an unmodded 6 speed CL-S and I have a modded auto CL-S. Now I know that my modded auto CL-s isn't as fast as the manual, but did you see the guys mods who posted this. All he has a an icebox for a mod.

So I will say this again based on experience of driving many G35's, a barely modded 6-speed CL-S will have a completely even race with a G35 and even you wouldn't have left it in the dust if the other driver was a comparable driver to you.

 

Granted all he has in an Icebox, but all I have is an Icebox and UR pulley. Yes all hp makes a difference but my point is that the race would've been a lot closer and he would've had a better chance at beating the G35 had he shifted past 6k.
Oh and you driving G35's and actually racing one against a CL-S 6spd is totally different....
Anyway, good races and next time show what the CL can really do...
