Bob, are you going to use any coatings besides the rocker arms. If I ever get my engine assembled I had planned to have the intake manifold coated as well as the combustion chambers. The email I received from Polydyn said the most bang for the buck was to have the crankshaft coated.

I figure now's as good a time as any for a couple of upgrades / minor maintenance items from my punch list. They should help increase fuel mileage.
I'm installing an electric radiator fan. To support it I've ordered a 65 amp alternator, smaller lighter battery (went with 405 CCA - should be enough since we don't reach freezing around here), new battery cables. Next I'll lean the idle mixture - I tend to run it a bit rich. I'll just have to get use to a lean mixture. |

Hey, if it reduces just 1 hp worth of parasitic drag at 65 mph, it will have a measurable effect on the mileage! Bob Last edited by RallyBob; 06-12-2008 at 02:29 PM.. Reason: mph, not mpg! Wishful thinking.... |

The electric fan is a good idea...worth a few hp in drag, as well as much quieter at cruising speeds! And lighter batteries are always a good thing. Last edited by RallyBob; 06-12-2008 at 01:37 PM.. Reason: dyslexia... |

This might help out a bit:
What is a crank scraper Opel I ordered the two-way all metal scrank scraper today from Ishihara-Johnson. One less thing to order now. Bob Last edited by RallyBob; 06-12-2008 at 06:45 PM.. Reason: more info |

Thats a nice thing to know, and it does help the MPG in a positive way.
Is there some special technic or can it be built by your self? |
