Dunnuck Racing OP master Joined: Mar 2007 Posts: 3,300 Northern Indiana	I am looking for some ideas from some of my fellow gearheads. I am working on putting together one o two dyno mules for testing various ideas. Most of the posts around here tend to lean toward how much power something makes and/or happy dyno numbers. I want ideas on what you guys would like to see. Would you be interested in testing that may help your car be more consistent? Or are big numbers all anybody wants to see? I have several ideas aimed at making a more consistent package I want to try. If you have some things you would like to see tested,please let me know. If you are willing to share them on here,great. You can also p.m. or email if you either don't want something in public,or are embarrassed to ask. I an good at keeping secrets if need be. I am not looking to to steal any secrets,or make money off anybody. I just want to try some new or unconventional ideas that may lhad to some good things for everybody. Keith www.dunnuckracing.com

Joe I think what J Rob is referring to is more for fuel efficiency testing. I tried figuring a good way to test my big block fuel mileage while towing while it was on the dyno. My biggest issue was knowing how far the throttle should be open for the test. I made several part throttle tuning pulls,but figuring mileage for something that pulls a heavy trailer is difficult. For comparing my engine/dyno to someone else's would be harder to do with fuel flow meter differences,in my opinion. Keith www.dunnuckracing.com

I have wondered some of this myself. I know some guys do some extensive lightening for the gains it may get them. On the heads vs roller valvetrain,I think a lot of people would be surprised how little extra power they get with a roller can over a good flat tappet design. Until you get into more exotic engine and head designs,I think its minimal. Might make for a good comparison test. Keith www.dunnuckracing.com

Yes again on the throttle opening--I wish there was an agreed upon LOAD setting that could be used. All we would really need then to get around the fuel turbine variance is to time how long it takes to burn through say a 5 gallon pail. I know this test won't be popular--But I'm weird that way sometimes, I wanna know these things.

Port to port consistancy improvements comparing CNC ported heads verses hand ported heads would be interesting. Also how about running some HP numbers at different engine operating temps, Synthetic verses petrolium based oils, roller verses flat tappet cams. Fastest 300

I like this one too, If i was closer I would volunteer my engine for the test, Standard pump vs HV pump. Maybe even an oil weight comparison. -Dustin 67 Dart, 9 second, 392" G3 Hemi 68 Barracuda 340 F/SA

Small block stroker builds for the highest longest torque curves using common off the shelf parts... nothing real high dollar or hi tech....Save the high HP#s for the lite go fast guys, build some torque monsters foolin with comp ratios , cams, intakes & exhaust

It has been suggested to me by a friend that you guys should p.m. or email ideas to me instead though. I have no problem sharing information,but sometimes things are beyond one persons control.
