No reason for 3" for 500whp on a DJ on the 3.7l motor. Actually, if you go with internal wastegates (which I did) you can have issue with boost creep/spikes on larger exhaust. I'm not sure if Frank went with external wastegates or not and would not have issue if so...but, he will still be fine with his goals on 2.5" exhaust. Maybe a little more wear on the compressors over time, but not much.
Now if you "massage" the downpipe(s) into 1" there may be issues.  |
Like you I did go with the internal wastegates. Like I said for the kit wise I stuck to your build for the most part. Simply because you had the same goals as me and the biggest reason to be honest this will be the first FI i did and you have struck me as a person that knows what is going on and how to do the job right. I am extremely excited to put this together and install it on my car. I have a buddy that is going to be helping me that is well qualified with this type of stuff and Sam told me that my kit is going to be shipping with the instructional DVD(thats why my kit hasn't shipped yet). It seems to me this 2.5 or 3 in exhaust is a ongoing battle like i said earlier to fuz and i think it mainly comes down to your goals. I am going to stay with the 2.5 and ride it out and see what happens. I have a strong feeling that it will turn out well and because of Sam's words which i quote "You will not be disappointed".
