The one you have isn't close to being maxed out yet, I'd not worry about it yet.

Kule.. I needed to hear that Gary. What about the 60-1? I would like to be a little more efficient you know? I have a friend of mine that says he'll buy my current turbo that's kinda why i want to upgrade so he can be a lot faster in his CSX-T..

It is but I don't think you will see a performance difference.

There are other factors besides the turbo selection in play.

[Ubmbass]

Like what? please enlighten me.. If you say there isnt much of a performance gain, then I wont buy it.

Its all about bottlenecks. You won't take advantage of a 60-1 unless EVERYONE is taken care of.

Thats going to be my next turbo.

The bad thing about the SC61 is that I would have to make a custom header to mount it cause it doesnt have a dodge flange.

That is true. The Precision Turbo SC61 uses a standard T3 flange. Which means its bolts right up to my car :big grin:

And it also requires an external wastegate. I hear this turbo has a 2 1/2 inch outlet.

The compressor side of the SC61 is the new Garrett GT35R compressor wheel. It can be installed in either a TO4E housing (3" inlet/2" outlet) or the TS04 housing (4" inlet/2.5" outlet). This wheel rocks. Blows away anything like the 60-1 for our cars. The effciency of this wheel at the pressures we run is much higher. The compressor also turns slower to move the same amount of air at pressures wed use on small displacement engine as well. The 60-1 works (I have a loaned unit on my car now as a test), but its certainly not ideal. Generally speaking, that wheel likes a larger, higher flow, lower boost engine to be in its optimal range.

You can get the SC61 in internal or external gate or with a 4 bolt or 5 bolt turbine discharge flange. Lots of options there.

Turbine choices are 0.48 and 0.63 and the housings are cast by Precision. Everything I have heard is that the Precision housings outflow the Turbonetics housings of the same size by a decent margin. So much so that Precision doesnt even offer an 0.82.

Turbine wheel choices could be just about anything youd want. Precision recommends either the T350 turbine (similar to the Turbonetics T3 Stage 5 wheel) or the T4 69 trim turbine wheel. But, you could also put a T31 69 or 76 trim in there (similar to Turbonetics T3 Stage 2 or 3).

Precision Turbo claims the SC61will flow up to 680 hp and give full boost by around 4000 rpm on a 2.0-2.2L engine.

You should know by now this is impossible in Sean's case. He's a genius and you're not....blah.

I have a 57-trim wheel in my turbo, and will be going with a 50-trim if someone will buy my turbo.

It's not well-matched for a 2.2, but I think a 2.5 will do much better with it.

I've done up an Excel spread-sheet with all the numbers laid out. Pressure ratio's, calculated airflow for a 2.2 @ 85% efficiency, and also lbs/min airflow for a given RPM and boost level. I'm going to extend my current spread-sheet to cover more RPM values and more boost levels. I may also do up a separate spread-sheet for 2.5 engines.

According to the numbers plotted on the turbo compressor maps...the 57-trim wheel would work better on a higher flowing engine (2.5) or a higher-revving engine. The higher boost you run in an effort to make more power, the higher the pressure ratio is and the FURTHER OUT you go on the compressor map efficiency rating.

A 50-trim wheel lands almost all plotted points inside the highest efficiency island on a 2.2 engine.

Look at your MPH bro...you've got a LOT of room before you exceed or even MEET the capabilities of your current turbo.

You have a good bit of mods you *can* perform before you need to upgrade your turbo.

Ken keeps saying it...bottlenecks man. "thumbs up

As usual, you dont know the full story nor what you are talking about at all.

Gary posted his message *after* we had a long conversation over PM about stupid arguing and the reasoning behind this post.

Its people like you that are always causing arguments with me, because you like to make assumptions.

If you had read my post however, you would see that it was actually not an argument at all. It was in fac t, devoid of all argument, but a simple "counter" for the negative 57 trim info.

Furthermore, everything you said here:

"According to the numbers plotted on the turbo compressor maps...the 57-trim wheel would work better on a higher flowing engine (2.5) or a higher-revving engine. The higher boost you run in an effort to make more power, the higher the pressure ratio is and the FURTHER OUT you go on the compressor map efficiency rating."

...is a reiteration of exactly what I said in my post.

Go read it, you will see.

(and here I thought this topic was dead)

Notice, once again, *im not arguing*.

Have you ever heard the term "tongue in cheek" It applies to the comment you are referring to...

No, sorry, I dont speak english.

I just looked in Websters re: sarcasm, it said see akuma.

We both know Chris's comment was completely unnecessary, but we also know its "ok" as long as I am the target.

Did he HAVE to open his post with an insulting statement directed at me?

I dont see how it added any relevant content at allm but was just another "dig", as usual

He would be the first to blame me if I retaliated, of course.

It seems to go that way often around here. As long as I am the target, anything is exceptable.

Example:

I was recently banned for "flaming" a user. Oddly enough, that user had flamed me much worse, without cause, several days before. ...no one seemed to even notice that.

The huge irony is, neither of US (the 2 actually involved) were taking it seriously, and we had sent several "friendly" PM's to each other that weren't seen in public.

I love how the admins dont ever seem to know WTF is going on.

This includes you, Ken

You are the one who created this whole thread based on my 57-trim for sale in the parts section.

There was even a link from my for sale post directly to this thread....

A highly indirect but still very blatant post flame.

On page one of this thread you even admitted to creating it here so as not to break your own rule about flaming for sale posts.

Alas, I sold the turbo anyhow, and all of the admins here can bite me.

(for example, the admin who *deleted* the 57 Trim For Sale post in question)

Since when do admins delete "For Sale" posts?

I wouldnt be suprised if this post got deleted, as it doesnt make anyone here look too good.

Of course, I also know that if it stays, it will somehow get magically twisted around to equal "sean would argue with a fence post" and "man you are such a loser all you do is argue with people" or in some way place all the blame on me.

A brilliant example is seen 1 page back. I made VERY sure my post could in no way be construed as argumentative. I was simply trying to dispell the negative posts about the 57-trim. Yet, amazingly enough, someone STILL interpreted it as me starting arguments "just to try and win".

Funny stuff all of this is really.

[shelbyglhs222]

It is funny because it is true...always on the defensive trying to win an argument. Everyone knows it.

[shelbyglhs222]

Here is a question...explain to me why this thread was stuck on 1.5 to 2 pages for a week or so. Nothing wrong with the thread, the weaknesses of the 57 trim were addressed and someone even posted that they had success with it. However, As soon as YOU post something it goes to 4 or 5 pages in a day. It isn't just this thread, it seems every thread you are involved in has many more, useless pages than it should. Notice a trend akuma??? Maybe its the fact that you aren't this genius you think you are and people just don't want to hear what you have to say.
