Has anyone removed or disabled The VTCS??

[thewrench]

Thought of another joke

you'll prob have the most powerful na p5 out there!

Which still isn't saying much!

EDIT: Oh man! Major threadjack, so sorry, back to your regularly scheduled topic!

aww I thought I was one of the most powerful n/a p5s before nitrous

 

[twilightprotege]

does anyone who has the most powerful NA P5???

it would come down to posting dynos really. Unfortunately my scanner/printer is broke and I don't know how to fix it

 

[thewrench]

Actually Equinox I think you probably are. But there's going to be a bunch of people stepping up shortly I think. It seems a bunch of us auto guys are going na. We'll just have to see what develops. Have you got a pre-nitrous dyno?

Any chance I can get a manifold like that for 200? =)

pre-nitrous dyno hit 132whp, 145wtq, just before I dropped on the port and polished heads.

 

[thewrench]

Did you do any work on the intake mani, sorry if you've covered this before. If I've seen it I can't remember.

Damn you wrench! I wanted that manifold! =) Its cool, but let me know how it all turns out as I am all about the NA power.

Hehe, I'm trying to figure out what order I'm going to do all of this, header's firrst, but I could do intake->cams->cam gears or vice versa. I'll let all know what happens. There was someone selling a new jspec mani on the forum somewhere for $400, look around for it if you can afford that because it was a decent deal. But I'd rather have what I got, sometimes it pays to not have a life outside of this forum.

I think (MacProtege5) Is one of the Quickest n/a P5's on the net. He beat few RSX-Type S's, MSP's...

 

[twilightprotege]

I look forward to seeing what the IM brings you james! i just wish i knew exactly what i want to do next to my car!!!!

 

[thewrench]

OK Twilight, I cracked the intake open today, and you are absolutely right, the VICS butterflies just lead to an open chamber. Makes you wonder just what exactly it does. I'll ask when I go to discuss cams, hopefully in a couple of weeks, to see what "they" did to the intakes. And in looking at the pics on Corksports website, I can't see how the Jspec mani would be any different. I can't see where removing the VICS butterflies would help. It would basically just add intake volume, but not flow, and may actually increase turbulence. You could remove the butterflies and open the upper chamber to the plenum to shorten the runners, but you would have to work hard to smooth it all out, and the runners would effectively be so huge you would kill any bottom end. One question, on your intake, are all of the butterflies flat? On this one, one butterfly is slightly bent.

Hope I helped you some,
James T

 

[twilightprotege]

yeah coll james! finally i'm right with something!!!!

that's exactly what i thought. it would increase turbulance. it just doesnt sound nor look like an ideal setup to me.

the butterflys...i honestly cant remember. but i'm guessing they should be straight as butterflys usually are

 

[thewrench]

You know I just thought of something, when the butterflies are open they block the main runners cuasing the airflow to run all the way up through the chamber and back around down the main runner, thus greatly increasing runner length. So with that in mind, would the butterflies be normally open, and close under high load , thus shortening the runner length. So it would be better to disable the butterflies, closed position, but leave them in place, giving shorter runners all of the time, right?

 

[twilightprotege]

that was the arguement i had with theman 1 time. the butterflys should be closed at high rpm not open as he claimed because having them open increases the runner length. you can see why the whole IM topic has been quite confusing and strange...

 

[thewrench]

Yeah, the more I think about it, the more that has to be true. If I can get to it to see, I'll try to take a look at the lever to see what position it's in at idle. I can see now where having the ability to control that would be helpful now.

 

[twilightprotege]

good idea. would be good to know the truth behind this...

Cool, now we are getting somewhere.
