So, with full bolt ons including catted TSP DP, kuro turbo, complete 3" exhaust, I D intake, PWR intercooler with pipeing, and of course Hondata with custom tune, the final #'s are 379/386 on a hub dyno. No fuel upgrades. Am I happy? You bet I am! A different dyno or tuner could deliver more or less.
This part arrived in excellent condition! Packaging was great and I am pleased with the quality of the downpipe.
I have no real-world numbers to offer, but I decided to upgrade from the OEM intercooler as I'm planning on doing a fair amount of track days with my FL5. Quality is flawless. It's a piece of art. One thing I noticed about this IC is it is very heavy. Much heavier than stock, so there are no weight savings to be had, but hopefully the heat dissipation efficiency improvement makes up for it.
I was a bit nervous after hearing other FL5 owners report noticeable vibration from other companies' rear motor mounts. Most PRL reviews were pretty positive, so I went with the PRL and I'm glad I did. I noticed no difference in noise/vibration/harshness, and mount seems to be doing the job with reducing wheel hop.
