1995 BMW M3 427 FrankenBimmer
Started on March 15 by cglass8444
My mission is to develop the outer limits of the road racing capabilities of the E36 BMW M3. I do DE’s so no rules & no spec. Hint #1: Roll cage built for 1000 RWHP. All looked good on paper two years ago and the reality is beyond expectations. Have been testing in incrementally increasing stages.
In 2008 ran a Chevy V8 LS6 350 ci with 400 RWHP & Torque…ran great all year. Chevy V8 LS3 bored and stroked to 427 ci with 550++RWHP & Torque ran the 2009 year…we will see where that takes us. If you are an old guy like me, you remember the CanAm and TransAm cars with 600 to 1200 HP…will be interesting to see where we end up.
Who knows, after 2009 shakedowns, may see us at the 2010 GRM Ultimate Trackcar Shootout!!!!!!
Thanks to the guys at Eurosport Automotive of Plano, Texas and Dallas Performance of Dallas, Texas for keeping FrankenBimmer in one piece.
