You don't need a I/C. I went 7 months without one at 6 psi on a stock bottom end. Would I do it again.... hells no but I was stupid.
As far as the t 25 being a better turbo at 8 psi I would agree with that. 8 psi should be nothing for that 57 trim but it will take it alot longer to spool then the t 25. The t 25 would spool sooner and at 8 psi it would pull you to red line with no problem. Look at the people with star kits running close to the same turbo. When they do dyno pulls at low psi they get lower numbers then people with the smaller t3's and smaller MIT. turbos. This is just a fact of life. Now at 15 to 20 psi the 57 trim would blow the t 25 away.
But I am considering a rebuild in the near future, therefore this turbo would also better suit me than t-25. I was always under the impression that a higher flowing turbo would flow more air and thus create more hp if the fuel was there. I guess not if it is out of its efficiency range. Just too much fabricated to get my car setup for a t-25, then redo it to get it setup for a 57 trim.
Booster2k said:Okay okay I see you guys are all on the defense about the intercooler, let me explain where I was coming from. On an 85 degree day At 8psi boost and a 70%comp effeciency on the turbo, the outlet temp at 8psi would be about 170F thats not that high! Therefore you dont NEED an intercooler. could one be of benefit, YES but its not required, def not a big expensive FMIC a good used sidemount would work fine. Now at 20psi your looking at temps closer to 300psi now see the big difference there! So all you guys that dont do the math, should figure that stuff before you go jumping ont he you have to have thing. Sorry to step on toes but I was just trying to save some headache and money for you!
Yea that is also like saying go turbo and skip the fuel though. Why risk those higher temps at all if you can have lower ones without that much more work? Especially when it fills your grill with more bling bling than Nelly's teeth.
. Makin my ic pipes was fun...and damn it's sexy, for custom of course hahaha. only short route for me
