I am currently running a Blower Shop 10-71 on my 540 with a Whipple Innercooler Intake. I have been very please with the intercooler. Not only for the fact that I only added an additional 3/4 of inch of height, verse 4-5, but also becasue it is one HD piece. you can also run it in salt water.
Do you have an 8-71. I ask b/c I may be selling my 10-71. Only 16-20hrs.
