i know, i was just trying to help someone not blow a lot of money on something that wouoldn't work that great for their car. like if someone was on here selling those "electric superchargers" for 200 bucks, i'd just have to say something if someone was actually wanting to buy one. And i believe i tried to refer him to this thread.

Even my 46 trim has its share of lag....I would say definately 46 or 50 trim...Although the 57 trim seems to work well in the 16 valvers with a huge intercooler.

just curious but what rpm do you hit the boost that your running at? I am just looking fo rsome comparison to my mismatched hybrid. with it's .48 turbine housing, stock wheel and .60AR compressor w/ 48 trim i have 15psi by 3100rpm.

[shelbyglhs222]

3800-4000 if I nail it at 3000..18 psi..but my mixture sucks..its fat down low since I only have an adj. regulator. And I also use the .63 housing. It pulls really good though when its in full boost..especially in this weather. Hey maybe if I didnt blow power modules every day I could take it for a spin and tell you exactly when its spooling.

[89daytonaTII]

yeah i know that my .48 housing is what is giving me my fast spool up, but will ultimatly be the car's downfall for not making huge power. there never was plans of going over 20psi anyway, and i got it super cheap. can you say less than 400US brand new

[mopar2ya]

I agree the 57 trim is a poor choice, the compressor map blows! I have a 50 trim stage two and it flat spools great and makes super power. I will dyno Monday for actual numbers. Whats funny is the back pressure blows my wastegate open to early, so I stole a trick from my friend. I have heavy carb return springs assisting in pulling my wastegate closed. The boost doesnt hunt around anymore and I can get the 25 psi I am looking for.

I have a 57 trim and for the longest time I was having spool up issues on the launch. I fixed some timing issues and built my transmission with a high stall TC (2500 static stall) and my spool issues are gone, I can launch at whatever boost I select. Although the brakes have a hard time holding me back sometimes haha. But I like my 57 trim it seems to pull evenly throughout the rpm range.. all the way up to 6000 rpm (where I shift)

[glhsken]

Before making a generalization... why don't you say WHY it works on yours ( I know). And if you look at a map, you would be surprised what you can learn...

[Ubmbass]

I agree I think it is very general to just say something sucks.. That's kinda like saying all honda's are slow. There are exceptions to every rule..

[ombomb]

I agree some things work VERY well on some applications, I had a super 57 trim on My turbo and it worked awesome! In fact If i coulda kept the head on the darn thing I'm sure I woulda found some weaker parts in the motor.

I made the post so the 99% of the people out there that wouldn't know what to do would avoid that configuration.

Originally posted by glhsken 57 trim is NOT a good match for our cars.. it's right on the surge line at spool up. That means it puts out more air at low rpm (while spooling) than the motor can handle. Sounds like a car with no BOV while its accelerating. I've know a 16V IROC R/t that had WORK done to it and went 110 in the 1/4 had this issue. If a 16v head couldn't handle it, how will 99% of the 8v's. Thought I would let people know. You want a quicker spooling t3/4, go 46 trim. You want the best power, go 50 trim.

Well, I wont even go into the inherently wrong reasoning behind the creation of this *entire thread* nor the trouble it COULD (and almost did) cause.

All I will say is this. I have discussed 91_ES's setup and it indeed *can* handle it. It is in fact the ideal setup for a 57-trim.

Its a 2.5 with a ported head and a 5-speed amongst many other mods. I am not here to lay out his setup, just to make a few comments.

To anyone reading this, you will note the cited examples of a 57 trim not working are all on 2.2 motors.

The fact is a 57 trim does flow more, but it IS on the surge limit of a 2.2. However, on a properly set up 2.5, it will work very well.

Also, it would also be superior to a 50 trim on a high rpm 16v 2.2 setup (7500rpm redline) but I dont see any TD people with that need.

Needless to say, dont believe everything you read.

[glhsken]

LOL... There are much better choices for a turbo. Even a 2.5 (though better) is not a good match for a 57 trim.

Your comment regarding a high flow 16v made me laugh. I guess that means a 2.5L will out flow a 16v 2.2.

A 57 trim is a good choice kinda like the turbo I had which didn't "exist" oh speedy guru.

For what it is worth, I know someone who went from this:
.48 A/R T3 Compressor Housing with T04E 57trim Wheel and .63 A/R Turbine Housing with Stage III Wheel

To This:
T04E Compressor Housing with T04E 50trim Wheel and .63 A/R T3 Turbine Housing with Stage III Wheel

I can't imagine why? He must be a complete idiot.

Yeah, his car only runs 11.30's now, I bet he is bummed.

Are there better turbo's? Of course. There are always better turbo's, Ken. There are turbo's far better than the 50-trim as
well. I am not sure how that is relevant other than as a failed attempt to be insulting, as is the rest of this "response".

Im sure it did make you laugh because we all know you are an expert on 16v's, right Ken?

The fact is, a ported big valve 2.5 CAN outflow a 2.2 16v on the low end where the surge is a problem. It's a simple matter of displacement. Remeber, we are discussing stock 16V vs Ported SOHC. The 57 trim is a flow wheel and the issue with it on a 2.2 is it is so close to the surge limit at lower RPM's. This is far less of a problem on a 2.5.

My comment regarding a 16V was not about "high flow" but "high rpm" where the 57 would have no surge problems.

I cant see anywhere in your post where you make even the vaguest attempt at a meaningful rebutle. Instead, I see thinly veiled insults. You might want to get back to me when you have something useful to say.

You see, these internet arguments are pointless and I am no longer going down that road with you. I was clear above that I am aware as to why this thread was started and I find it a bit sad but I am not going to discuss it or argue about it.

Here is a shocking revelation. I know what I know because I learn from my mistakes. There was a time when I did not know the simplest of car related things and even thought I knew some things that I did not. I didn't magically wake up one day and know all about TD's or anything else. I recall the conversation you speak of relating to your turbo (which was QUITE a long time ago) and how it is at all relevant to this conversation, I do not know. I learn something new everyday. I know 10 times what I knew then, and I will know 10 times more next year. This "oh speedy guru" does not stagnate nor become stubborn and rigid in his beliefs.

I simply have stated the facts. Do not believe everything you read. FM obviously thought it worked well for the 2.5 as that is what they used in their car and what they sold as the "Enforcer 3".

No one (including myself) is trying to argue that the 57 trim is for everyone, or even ideal for most. However, for this particular combination, and for *the price paid* it is an excellent choice.

I believe I have made my point clear and effectively sidestepped your obvious (and dare I say, typical) attempts to downplay and devalue my opinion.

In the future, please stick with intelligent meaningful responses.

If you are still reading this and have intent on responding, please go back, and read it again carefully, first.

If it is a flame, dont bother, I am not responding to flames. If it is factual concise rebutle, then you probably did not read this post correctly.
