Thought you guys might be interested in this.
I am building an M5 high speed car for the Texas Mile, Silver State and Bonneville.
Anyone who may visit "Rennlist" might know that this is a serious undertaking with full Nascar style cage, etc., etc.
The car is NOT being built with the street in mind, so we do not really have to compromise.
The turbo is GT4788.
The exhaust plumbing is 321 SS to be routed under the engine (ALA 944 turbo) - this I am going to say is easier than canting the engine upright.
I can not use a Burns 6-1 because they are as big as a trash can with the primaries I am using and it wont fit.
We are confident, however, that the Tri-y will still enable over 1,200 crank HP relatively easily. We are talking big Tri-y here.http://www.m5board.com/vbulletin/images/smilies/santa.gif
The management will probably be Link G3.
Compression is 8:1 with the new Mahle motorsports pistons, if they would be so kind as to make them for me, they have been fantastik in the baby Porsche. Bored to the minimum with torque plate, dry sump, 3 gallon tank at the rear, disabled stock pump, 3 044's, etc., etc.
My biggest concern at this point is the head.
It is to be flowed as baseline next week -what am I to expect at .5" 28IN/HG? Anyone here?
The intake ports look small to me??
Obviously, I will work the entire head and fit largest possible valves,but I am dying of curiosity - as I have a machinist cad writer friend who says it flows under 200 stock.
Please, all input is welcome.http://www.m5board.com/vbulletin/images/smilies/M5launch.gif
