Oil Temp. ect. we are not exaclty sure what temp's we should see on this new engine and want to keep an eye on things as we run it. Any info will be appreciated. Thanks.

The bottle sits on the floor of the baggage compartment and is attached to the back of the flap motor housing with two clamps. One clamp came from a defunct CO2 bottle and the other is a large hose clamp. I drilled through the clamps and the housing and attached them with #10 flat head screws and nuts. I'll email you some photos.

EGT's are running in the upper 1300's during cruise. I think you want to keep these below 1450... I kept mine below 1425 at all times. CHT's are running in the 380's on the back two cylinders and cooler on the front two. My engine guy (BPE) said DO NOT let the CHT get over 385 on the ground.... on climbouts mine will go up to about 410. I think you want to keep these below 425. I have a firewall mounted oil cooler and temps have been running around 180-190 and that is with half the inlet blocked off and the OAT being in the 50's. I've had it go up to 205 during full power runs or long climbs. I think 210 is probably a good number to stay under.

Good afternoon Dan Checkoway was kind enough to give me a ride this last weekend in his beautiful RV7. I am in the final stages of deciding between beginning an RV7 or an RV9. I was wondering if anyone on the list in Southern California (or in DC area on the weekend of 22 April) might be so kind as to give me a hop in a 9 so that I may have the basis to compare the handling characteristics? Any input regarding RV9's performance as an IFR platform would be appreciated. Thanks Steve Streiker Stephen D. Streiker steve@streiker .com - personal +1 323 252 0277 Mobile +1 310 335 4786 Office
