<VV> FAST to come - turbo boost but for how long?

[Matt Nall]

AHH  glad you asked....ggg

Here at 4500 ft....eastern Sierras....  read COLD winters.... a perfect "TEST LAB"!!

I have discovered that the rear grill is very restrictive at high rpm....and have fabbed several rear EXHAUST DUCTS to enhance  engine cooling.

I call these, much to the chagrin of a certain Aero Engineer; as you know,  " REAR DIFFUSERS". I even add strakes on the bottom to " straighten airflow"

GGGGGGGGGGGGGGGG

Seth,  if you recall the conversation at your table in SAC...the guy who was familiar with Alturas...and the Madelin Plain?  Where we said if your car won't make the 30 miles in 15 minutes.....you need another car?

I can run at 135 indicated [ wrong / small dia. tire] for 15 miles before the Headtemp reaches 500........at   5F.......12 miles at 25 F  air temps

note:  500F on the gauge is most likely 550F as the system cal'd out at 40 -60 F low thru the full range.

I currently am running a Nascar  COT  style front dam / splitter....and this has proven to help  as well as slowing the car slightly.....it actually WORKS!! ggg

    An engine that, 1st time......gives 8" in 1st,   12" in 2nd, 18" in 3rd and 
    25" in 4th...... this is as you pull out of the driveway after letting the 
    engine warm to 320f.

    I 'm at 4500 ft elevation and run 92 octane....so far so good.........once I 
    move home at sea level......we'll see how it acts....
