Hi All,

I just finished getting my Burtz engine installed in the car and ran it for the first time. It has the Stripe oil pump and a full flow filter. With the old spring I was getting 50 psi oil pressure at 2,000 rpm in the old engine (insert bearing and pressure lube). This is more than what Terry recommends. I bought the lighter springs from McMaster Carr as recommended by Stripe. I sent several of you springs because McMaster Carr sells packages of a dozen. (I have more is anyone needs them.)

The new spring did not contact the relief valve so I stretched it out, increasing the length by 1/2 inch with no load. I recommend you do this too.

I am using 10W-30 oil as an engine wash in case there was any crap built into the engine. I will drain it out and replace it with the heaver oil that Terry recommends in about 50 miles. At 2,000 rpm I am getting 25 psi and at idle I am getting 12 psi.

By the way, the Burtz engine is a sweet running engine. I am very happy with it.
