Does vtec work in reverse?

Off subject but who cares, I just bought a Supra TT today. 14 grand, what a deal. Truth be told, I probly wont talk to you losers any more. Moving in with a new crowd. Supra Baby!!!
well, maybe you did deserve to get banned. I'm glad you have a Supra owners mindset already. Shouldn't have a problem over there.

Did I miss all of this. What happened?

shiet, I thought it was exman98...turns out it's the one fucker again. God I wish they could just IP ban his ass.

hey

that has not me that posted that look at the end of his name he has the - ' -
i on the other hand do not

i thought your ass got banned and you came back with a new SN.

knew it was an imposter so i didn't bother replying
you're not a tool, and that guy clearly IS.

There were questions about my statements.

Again, my D16Z6 revs to 84-8500 because I have a PR3 OBD1 ECU. The OBD1 B16A has a redline of 8200 and a fuel cut off of about 8500. It plugs and plays with a D16Z6. It allows me the B16A fuel cut. I only get a check engine light for knock sensor.

My traction breaks loose because the B16A ECU kicks VTEC at 6000, after my non-VTEC lobes have long run out of power, causing my HP to yoyo severly at VTEC.

Then at 6000 the HP goes from below stock @ 45-6000 RPM then it's suddenly brought right back to near peak HP just 100 RPM later

Do I have to explain that again?

Let's estimate MY dyno.

3000 79 HP

4000 86 HP

5000 75 HP

5900 70 HP (Still running on pre-VTEC would cause HP loss)

6000 115 HP (VTEC Hits, jolting the car from 70 to 115 in a matter of 100 RPMS)

7000 120 HP

7300 128 HP

8000 105 HP

8500 90 HP


These are just estimates, and they show you my powerband. The numbers are off, but the order they appear in are correct for my car. Yes, my powerband DOES infact go higher than stock, since I'm getting more fuel at higher RPM, and the peak HP is infact higher than a stock D16Z6. Other than that, I got straight air to the throttlebody unfiltered, and no muffler.



:lol2:

ok, I really doubt that a SOHC engine with vtec on only one set of lobes and not both I/E lobes, is going to crossover and increase power so much that the tirs break loose when it hits. no matter how late it kicks in. Ive idden in modded DOHC VTECs with alot more power than stock and theyve played wiht the fuel and everything and when vtec hits there isnt even the slightest hint it came CLOSE to breaking the tires loose. its juts not gonna happen. only way I see it is if yuore on ice or perfectly smooth concrete with sand sprinkled all over it.

i'll just put vtec to kick in on my VAFC at 2,000 RPM lol THEN reverse and i'll tell you if vtec engaged or not ;) lol

^^^ thats actually a good idea

would you be able to hear/feel it way down at 2k?

I"m sure you could hear it if you have your foot in it.

yeah, I guess so, just seems that since at 2k you dont have any power no matter what lobes youre on you wouldnt be able to tell. it would most likely bog down if anything if you crossed over to the high-lift lobes so low wouldnt it?

nine pages of absolute crap... well.. take it back... 7.5 pages of absolute crap... some worthwhile crap... damn...

And not meaning to be too much of an ass and bring up something that was SO 3 pages ago, but even though I love hondas dearly, honda never has and never will have anything out of the box like the SR20DET. Period. End.

I dont know about that "never will" statement. noone knows that for sure. I doubt they ever will but who knows for sure.

F20C?

F20C?

almost threw that one out there, but didnt know what factors she thought of, like price maybe, or that the SR20DET actually goes into alot of nissans where the F20C you cant really swap into your everyday civics/integras liek the SR20 drops into the 240's/sentras and oim guessing someone somewheres dropped it into the HB....

F20C is fun, but it's not nearly as versatile, and it doesn't have the same power... turbo an SR20 and turbo an F20... SR20 still wins. Like I said, I'm a honda girl all the way through, but hondas are, by nature, slow. Just the nature of the beast. :) And I'm also talking about versatility... Nissan has the overall quicker cars on the drag strip, and they also own the drifting scene. And if honda ever makes something comparable in badass-ness to the R34, I will personally write this statement on a piece of paper, put mustard on it, and eat it. :)

And not meaning to be too much of an ass and bring up something that was SO 1 page ago, but you are still posting, 5 posts later. I think it's safe to say this isn't all crap. In your defense, nissan is one of the import scenes best TURBO cars, but for n/a, I will always go with honda.

how would you know if a turboed F20 would make less than an SR20, there is no proof out there. There isn't even a single company that produces a turbo kit for the F20, RevHard is close to releasing their's, but it's still not available, and I believe they will be the first to do so. You have no facts to back up your claims.

You say Nissans are overall quicker on the strip, I don't know of any nissan hitting sub 7's like Stephan Papadakis. Or even 8.5's in his retired FWD car. The only reason Nissan "owns" the drifting scene is because they have cheap RWD cars to choose from. How many Honda's have RWD before the S2K besides the NSX...NONE. No one is going to go out and buy a $30,000 car just to put it in a ditch or a wall for the sake of drifting.

Anybody know who banned bruce. True he caused trouble as other sn's, but if he was behaving now, why ban him? He'll just go back to his old ways again. I just read all his posts and saw nothing wrong.

reason he keeps being banned is because he keeps coming back. Usually your first ban is only 1 week unless you did something to really piss the admins off. At this point I'm guessing only a 1 week ban is out of the question considering his re-registered about 10 times.

Again, thanks for the concerns gentlemen. GScivic7, I wasn't aware of the one week limit. I'll take that into consideration should I find myself banned again. As for the administration. I gave a sincere apology in my signature as 'bruce'. I went as far as to list my former names so the apology would extend to anyone who was offended by a previous post. A true gentlemen...

what you should do is PM the admins and see what's going on with your ban. At this point, I wouldn't be surprised if they had you on permanent ban and not just 1 week.

This is a fu*king long thread. Kill it.

vtec works in reverse but i dont recommend doing it b/c u can easily blow ur tranny b/c an engine is only meant to go a certain speed in reverse.

GS... is there any particular reason that you're busting my balls? just curious, cause you're bein an ass.

And F20 turbos (removed kit cause it's not a kit) do exist... custom work, yadda yadda, but turbo S2k's are in existence. Fun ride, yes, but a similar setup on an SR20 had more potency.

And how many people do you know that have the funding to build a car like Pap? Yeah... I know I don't. If you do, by all means feel free. I like to keep things realistic.

you wanna know what my problem is. You, a mod, are coming on here posting false info. Show me some proof to your claim and I will step back and completely apologize.

Mods... I think we all know how I feel about them.

what you want turbo s2k numbers? I don't have them, but I can get them from the shop that did the work. None of my info is false.

And logan... you've been banned before for being rude.... Seeing as how this is not my forum any longer, I'm not doing anything, but knock it off.

I am a gentleman and would never willingly offend a woman. Truth be told, I'm drunk. I'll log off now. Don't worry, I'm not driving.

PS. Page 11 WOW! What did you say about this thread on page 9?

better not... a live, asinine AF'er is better than an injured one.

alright, here's the answer, i haven't read all the way thru, but i haven't heard it yet. vtec is engaged by rpm. yes it is hydraulic, but the hydraulics are electronicly controlled by an rpm switch. the reverse gear is the same ratio as first gear, and last i checked, you do hit the rpms needed vtec in firstgear. also, the ecu has no idea what gear you're in (when driving a manual) so atleast in a manual, vtec will kick come on in reverse. answered?

and to those that stated, vtec isn't switching lobes, you're half right. in the sohc vtec motors, no it is just a timing change. however in the dohc vtec motors, yes there is a second set of lobes and the cams are shifted to utilize them.

Ok ok. VTEC works in reverse.

I hopped in the passenger seat of my friends '03 RSX with video camera in hand. We set out to a long, long highway road. Slapped her in reverse and let it go. Got up to about 35 in reverse... maybe 40, wasn't sure. I was more or less focusing on hanging on, not dieing, and such. However, I was positive that I heard it kick in (I got a Teg, I know what it sounds like :) )

After that he brought it down and kicked a J-turn, then dropped thee ol' clutch and we were off back home.

There you have it. I hope that helps. =0

I restate again to clear confusion. :biggrin:

yah, uh wrong. The SOHC motors' camshafts have a second set of lobes too.

And the cams don't shift on DOHC VTEC motors. Cams only move in 1 direction, and that's in circles.

You really need to check this out and learn how VTEC works before spreading your bullshit.

RIP this thread !

alright, here's the answer, i haven't read all the way thru, but i haven't heard it yet. vtec is engaged by rpm. yes it is hydraulic, but the hydraulics are electronicly controlled by an rpm switch. the reverse gear is the same ratio as first gear, and last i checked, you do hit the rpms needed vtec in firstgear. also, the ecu has no idea what gear you're in (when driving a manual) so atleast in a manual, vtec will kick come on in reverse. answered?
how is it hydraulic??? Last time i checked there is no hydraulic fluid running through the head on VTEC motors.

well let's see hydraulic doesn't have to run on "hydraulic fluid". the word hydraulic means "of, involving, moved by, or operated by a pressurized liquid." i.e. ENGINE OIL. No, SOHC VTEC heads, do NOT have a second set of lobes, open up a z6 or y8 head and you will see you are wrong. Yes a B16A and B18C have a second set of cam lobes that are activated by VTEC. Has anyone here actually looked inside their engine??????

...i cannot believe this thread has 11 pages of posts and STILL no answer. Some mod, PLEASE kill this thread.

and about the VTEC kickin in, in reverse, i again state, I had not read through all the pages to see if it had been answered so I apologize for not giving you credit Wischmaster. You did answer it and you were correct.

lol...so explain to me how the valve timing changes on a SOHC motor then.

lol...so explain to me how the valve timing changes on a SOHC motor then.

there is an extra set of cam lobes which are actually on the same camshaft as the normal ones, and it works the same way for the sohc shafts. the little fucker actually gets pushed out of the rod by hydraulic pressure, its not on a different shaft.

thank you kcapp122

lol...i know, i was calling him out, which he didn't step up to.

I'll say it again, know what your talking about before you go spreading your bullshit

thank you kcapp122
dude, you said there weren't a second set of lobes lol

wait, no the sohc does not have a second set of lobes

i didn't say there was a second shaft it's SOHC motor, SINGLE OVERHEAD CAM, i said tehre was a second set of lobes which there are, just like you said.

i am trying to read and type and reload all too fast, some one please open a head and look. the sohc heads do the following:
simply put, the VTEC solenoid has oil running through it to the camshaft journals. When the rpm switch is triggered, the solenoid is activated and further pressurizes the oil going into the cam journals.

no, i have a D16y8 head sitting in my garage open. no second set of lobes. the DOHC heads have a cam for intake and a cam for exhaust. both have two distinct sets of lobes. one set for normal fuel efficient operation, and a second for us power hungry pedal stompers. sohc heads have one cam for both intake and exhaust, and you tell me where in the hell the other 16 lobes are at on that cam.

omg you are worthless

this is how VTEC works.

When the temp is right, the oil is not low and the ecu does not go into safe mode. And when the motor's rpm hits VTEC crossover which is usually somehwere in the 5000 rpm range, the VTEC solenoid sends pressurized oil into the head which pushes a small rod that connects two rockers and a third rocker/follower. A bigger cam lobe on the shaft actuates this third rocker which is inbetween the other two. This is how valves get more lift and higher duration.

SOHC heads do have one cam, VTEC only works on the INTAKE side.

but thank you for proving me right, the sohc head has ONE set of lobes.

nope, it has 2 sets of lobes, the regular lobes and VTEC lobes

hey i'll will gladly admit u r right. no bad blood at this end

sorry, but i hate know-it-all newbies, goodbye

i'm looking at it. that's the whole reason sohc vtec is crap compared to dohc vtec. no second set of lobes.

lol, wutever.

p.s. just because i joined this yr, duzn't mean i was born this yr too jackass

okay, just to get you to shut up. Look at this pic.

http://www.overboost.com/obs/product/skunk2_S2_SOHC_VTEC_Cam_1.jpg

notice how inbetween every two intake lobes there is a bigger third lobe. If you still don't believe me, count the number of lobes on there.
