Does anyone have any experience or dyno sheets of a 57 trim? I've seen the power #'s of the 60 trim, am very impressed, but still have the surge issue in the back of my mind. If anyone can add any input on these two turbos, that would be great.

Thanks,
Mike

i haven't ever heard of the 60 trim surging, sure people talk about it - but i've never actually seen or heard it happen first person. i really think either wheel would be great.
i went with a 57 trim though, simply because i had a compressor housing for a 57 trim sitting around. should have the install finished this weekend.

I was going to go with the 60 trim, but was talked into the 50 trim wheel by a number of people, being that it's a GREAT pump gas wheel. I'm hoping to see close to 500 on race gas and in the mid 400's on pump. Will not have to worry about the surge of the 60 and 57 trim wheels, and should be just a quick with pump gas.

Yes, the 50 trim has put out some damn impressive #'s, as has the 60 trim. I've spoken to someone that has run 10.6 with a 60 trim and he loved it. He said it would surge for a second on the dyno, but never anywhere else (due to the 3rd gear roll and then punch). The 60 trim makes more hp than the 50 trim ONLY at 27psi+. Otherwise, I agree that the 50 trim is one of the best pump gas wheels out there.

The reason I'm not including the 50 trim in this discussion is the fact that you can get a 60 trim for about $200 less than a 50 trim. I KNOW what the 50 trim can do, it's been discussed before, dyno #'s talked about. The 57 and 60 trims seem to be largely ignored or looked over and I'm looking for input on them. I know Kevin at AGP doens't recommend the 60 due to the surge issues, but I was hoping to get more feedback from actual 60 trim users.

Thanks,
Mike

Wow that makes me feel good about getting a 50 trim. I just ordered it with a FMIC and newgen wastegate. Hope to make 350 on pump with safc and 550cc injectors.

I have a 60trim going on my car next year, but I got a stage 3 .82ar exaust which should make up for the surge, and make a little more power. My plan also includes n2o later in the year. What kind of numbers have you heard with the 60trim? good luck.

The numbers i've seen from two diff. people for the 60 trim are....

26psi = 450whp
30psi = 486

Another DSM put out 32-33psi = 500whp

That's when mated to a stage 3, .63 a/r turbine housing.

Surprisingly, the 50 trim put out 487whp at 30psi as well. So, the search continues

I ordered a 57 trim from agp a couple of weeks ago. I was debating the 50 and the 57 trim wheels, so I called agp and was told that the performance of the two wheels is pretty damn close. So I opted for the cheaper off-the-shelf 57 trim t3/t4, as opposed to the custom made 50 trim setup.

Is 350whp posible on 550's and pump gas? Souldn't you go with 660's?
And what FP do you plan on running?

Here's a little info on wheel sizes for you guys. Ever wonder why the 50 trim is such a bad ass? If you want more, just ask. Turbine wheels, compressors, T04B, T04E, you name it, I probably have info on it.

50 Trim
Inducer Diameter: 2.122
Exducer Diameter: 3.00
Flow Rate: ~ 47 lbs/min

54 Trim
Inducer Diameter: 2.170
Exducer Diameter: 2.950
Flow Rate: ~ 45 lbs/min

57 Trim
Inducer Diameter: 2.230
Exducer Diameter: 2.950
Flow Rate: ~ 49 lbs/min

60 Trim
Inducer Diameter: 2.290
Exducer Diameter: 2.950
Flow Rate: ~ 50 lbs/min

What do you guys think of the 48 Trim as used on the SBR-GT10?

48 trim
• 2.08 inducer
• 3.00 exducer
• 44 lb/min compressor wheel

If you want info on the T3/T4 wheels/housings, go HERE . The site is kinda old, 1998 catalog, but the info on the wheels/housings are still the same. Ignore the pricing, as it's old retail prices.

Mike... you know I have a 57trim/stage 3 in a .48 Housing... and you know it pushed me to a 12.09 at 119 on 24psi with a stock 2g motor/stock intake manifold (well, I have webcams...).......


I think that says a LOT about that turbo, personally.... I don't plan on going any bigger then what I have -- it's perfect for my car.

Uh no. That is about the most vague info you can find. Good ole tur"blo"netics

thats nice info 500whp on the 60trim. T-100 180lbs/min....

is there a huge lag difference between the 50 and 60 trim? and do you have info on he 60-1?

60-1:

Inducer: 2.324
Exducer: 3.00
Flow: ~ 65lbs/min

The compressor map shows that it performs best at lower pressure ratios, but people have proven time and time again that it will also work well at higher pressure ratios. By looking at the compressor map it looks like this wheel just sucks ass at higher PR's. Theoretically it wont perform well. Pragmatically it does a great job. To hell with the compressor map on this wheel.

jeff

thanks for the info..
