C7 Z06 Dms 800 Package Review - Procharger F1a
Hi everyone,
I believe I will be helping more than a few people today with this write up as there is much to learn for C7 Z06 owners who want more out of their cars. Regardless of what I write here - do your due diligence - the information is out there but isn't the easiest to find sometimes...I thank Manny Dasilva and Dave Rempel - with the entire Dasilva Motorsports Team for making this happen...it was a cool journey...and it ain't over yet lol...
Background:
I was not satisfied with overheating issues of these cars - nor the cause of this overheating - the absurdly tiny Eaton TVS 1740R blower. I am a turbo guy - and I found SC's pretty frustrating.
I first tried upgrading this setup with IW 18% lower, a 2.38 upper along with AR 1 7/8" Headers and a Halltech CAI. I knew over spinning would make an already poor cooling situation worse - so I added a CR primary rad, GM secondary rad, Dewitt heat exchanger/intercooler and oil cooler.
A billet 160 thermostat and CR catch can rounded everything out.
Despite all of this cooling, the magma hot SC and lack of circulation in the engine bay still made for over heating so I added a one nozzle (15) Alky-control solution. This made the greatest difference - and in 90% of the situations - no issues. That said, in 95-97+ F temps and humid weather - with running the car in a spirited fashion - the lack of circulation would become too much - sometimes vaporizing the meth in the lines before it even reached the engine.
So I had to make a decision. Do I try something different - or get rid of the car? I really liked the car - and to be fair - the DMS 700 package did what it was supposed to - but GM design issues (lack of engine bay heat circulation and ultra tiny SC) got in the way. I made 680/716 at 14 psi on this build and ran a 135 MPH trap in the 1/4, all in 100+ F heat. No cam. That was healthy power. With a tire, this setup was very driveable - but on the crappy for street use sport cup 2's (which need constant heat - and cool very quickly unless under constant load) - I was spinning quite a bit with the tuned, over-spun low-end roots-type SC as well as an already torquey LT4.
My Decision:
I believe we were the first C7 Z06 in Canada to try the F1A procharger. I picked this particular PC due to its "goldilocks" size. Bigger than the P1SC and D1SC but still not the top like a F1R or X. I don't count F2-F3 PC's as these are race-only solutions and I wanted a street car. The toughest decision was whether to...
