My front bumper is off to get repainted to repair general stone chips and other general defects which have been bothering me for some time. While its off, I decided to revise the intercooler setup on the car. The car was running the twin, 3.5" Procharger intercoolers but I decided on trying a large FMIC to see if there would be any efficiency gains. The LS cars get all the fun with the 4.5" ICs but these were not an option since the inlet and outlet are very different. The 3.5s are rated to 700hp (combined). The dual IC system basically has a split pipe from the Procharger outlet. One IC sits under the passenger side headlight (horizontal) and it's the same on the driverside. The passenger pipe on the passenger side requires removal of the front bumper support since it travels over to the drivers side to go into a crazy assortment of merges before finally going to the main charge pipe under the hood. Most of the pipe size is 2.5". The new setup will be all 3".
The current setup works fine for basic highway pulls but after a few runs, the IATs climb which pulls my timing. I am running meth injection however I want to keep the IATs as low as possible. I could noticeably feel the drop in power at the track last season at the top of third and through fourth.
The goal would be to pick up some CFM, reduce any restrictions and see if I can keep the IATs under control under prolonged boost. Also while the bumper is off, I had a Burkhart front bumper support which I sitting around which I haven't done anything with. Below are some pics of the intercooler (31x12x4) with the front bumper support. My buddy has an industrial welding shop so we were able to fab and weld in some brackets for the FMIC.

I will pull it off and paint the entire front bumper support so it looks nice.....for the internet but mainly for rust prevention.
