Ugh. This thread is terrible.

The turbo doesn't spool at idle for several reasons.

1) It's not the size of my pinky fingernail, like many DSM, nissan, srt-4 turbos are.

2) There's no load on the motor, and since the turbo is larger than the aforementioned turbos, it will not spool significantly unless there's load on the motor (IE: driving, on a dyno, or two-step)

3) Why are you revving the piss out of the motor at idle anyhow? Parkinglot wars? Showing off?

X3..basically the answer to your question

First off, DSM turbo's arent that small buddy. And the reason you notice them more than you do the 7m is because the DSM is often vented to atmosphere. Not only that its under load at a smaller rpm since its a friggin 4 cylinder. You do spool your turbo in free revving (ie. clutched, or out of gear) you just build boost pressure.

Next why the hell are you trying to rev your stock car without the accordian hose on? Its not spinning cause u just stalled the car stupid.

Oxymoron?

I thought I was the only person that noticed the revving the piss out of the motor at idle comment too. But why the hell is he free revving the piss out of his motor? :3d_frown: Im guessing highschool parking lot and trying to show off.

If you were vented to atmosphere you would notice the BOV pop off in a free rev. there is still a pressure wave during free rev. DBB turbo or CT, they still spin. And 16g, 12b or CT-26 will still produce pressure at free rev, it just wont produce boost. The air pressure going into the intake doesnt surpass what is going out of the exhaust, thus boost is not created.

Difference is this is Mod :love:!

I am in no way, shape or form, your buddy, buddy. I don't feel the need to justify what I stated, as chance are, you'll just take it the wrong way like I've seen in all your other posts.

Oops, I made a mistake, sue me. I am human. I meant out of gear free revving.

"Spooling turbo". Just the thread title tells you where this one is going.

 

[figgie]

This is the TECHNICAL section folks. If you are stating the following


Speculation
Heresay
Opinion

DO NOT POST because you will get called on it.

its cause its not a Duel BB turbo, the CT is a jurnle baring turbo, so there is more restence

ATL88Supra

That statement is incorrect. ball bearing or not, the CT26 will not do that in our cars as the very thing of a turbo that makes a turbo work is pressure differential. No load means less fuel and there by less volume out of the exhaust.

two stepping cuts ignition at a preset rpm and acts "like" a rev limiter to build boost off the line

Oh boy

A two step does not build boost any more than pegging your motor at stock redline. A two step is known as a stutter step for the reason that the window is configurable (red line at 4400 rpm and 500 rpm above kill ignition). Since ignition is cut and fuel is not. You get the combustion process happening in the exhaust manifold and not the engine cylinder. Unfortunatly, in a 2 step the ignition timing is not configurable and as such leaves the unbrunt fuel to be burned at uncontrolled times (relying on the next cylinder to ignite the fuel).

Umm i dont see how I can take that wrong, as I own a DSM, and have a few friends with SRT-4's. I have delt with the stock 16g turbo of the DSM's as well as the 14b turbo aswell. And unless the line to the accordian hose from the BOV is removed it sounds just the same as the 7m. And just so we are clear on this, my dsm is a 90 GSX eclipse with a 6bolt 4g63T a shep tranny, and way more hp to all 4 tires than i could ever need. DSM is what first got me into the import scene, and as my eclipse finished as my project, i was given an offer to buy a mk3 supra of which i figured it could be another fun project. I am well educated in DSM, and am learning more and more about the 7m. That is the only reason i made my point, side by side the turbo's are pretty much the same, except the exhaust side for the DSM. Its a bit smaller. If i still had a 16g turbo around from my eclipse, i would post up comparitive pics.

The 16G turbo is a decent amount smaller than the stock CT turbo.. BUT thats not the point of this thread.. i hate how someone posts somthing on this site and you guys just start jumping down each others throats about somthing other than what is posted.

What was asked might seem stupid to some of you, but the kid looks like he is new to all of this stuff. So instead of bashing him, or each other, how about trying to help the guy out?

I don't care if you have a 4g63t mounted in your abdomen and have all that power to your feet, really. I'm done with you- you deserve no answers from anyone simply because of your attitude.

Thread back on track now- please don't post anything else in here unless it pertains to the OP's question.

 

[WhtMa71]

The OP's question has already been answered a few times and the thread has turned into useless off topic garbage. Why not lock it?

Good idea
