If I remember correctly, the Chaparral's automatics were based on modified Chev Powerglide units

Ronnie, you know that you're going to have a good case of writer's cramp just from the people on this forum Needless to say, put me on the list It'll sit next to my old version Dennis

Howard I think that you've got it Remember that all wings have induced drag and on your vehicle having the additional drag from the wind attachment supports to the vehicle body Exhausting engine heated air below the wing will help engine bay cooling and lessen that negative pressure drag below...

It would be interesting to run a small tuft test of the rear quarter of a GT that could show flow patterns adjacent the wheel and through and aft of the diffuser The GT has enough similarity to a 40 that it could probably answer in better detail what we're looking at theoretically GT40...

It's easy to trip laminar flow into turbulent, a rivet head is enough to do it Converting turbulent into laminar is next to impossible considering the limited space that we have in our vehicles The suspension components that are visible to underbody air flow just before the diffuser produce only...

I believe that the trick to the diffusers is to keep a constantly accelerating airflow attached within the diffuse to produce downforce If the cross section area increase too rapidly, the flow will separate into turbulent flow with subsequent reduction in downforce The reason that a flat top...

Hello GJ I remember seeing one on an Isdera Erator and I understand that it was probably Lexan, a clear polycarbonate It would definitely work and might make tight parking a little bit easier in addidtion to its aerodynamic down force advantages BTW, nothing wrong with your English Dennis

The one on the far right is the one that you want 412hp @ US$6.999.00 5.0L 444lbs Ford Racing Performance Parts - [Crate Engines] Sorry, this is all US stuff so you'll have to do a little local searching Dennis

Hello Randy Would appreciate you posting results for Single 4BBL carb vs 4 BBL throttle body power differences and if any fuel consumption and drivability advantages found Thanks in advance Dennis

Take a look at page 85 of Karl Ludvigsen's The Inside Story of the Fastest Fords It shows cross section examples of the changes made to the J car honeycomb chassis after Ken Miles unfortunate accident I'm not sure if I can post a page of this book that has 2 good pictures, it's worth a look at...

I always felt that the leveling of the playiing field should be done by the manufacturers, drivers and vehicle set up personnel I still remember back in the 50s when a Porsche 550 Mexico Spyder showed up to race against a bunch of MG TCs , TDs and a few other Porsches Level playing field, hell...

I was at the ALMS race this past Sunday at Elkhart Lake and had chance to gab with one of the set up persons for the single Ford GT entered It was a very interesting 10 or so minutes I aked him how fast their GT was doing on Elkhart Lake's main straight, a little over 165mph I noted Kirby and...

Pictures are great but those that did some speed on the track should talk about that Daryl was so pumped up he could hardly get out of his race gear Some saw 170 on the main straight, for instance I haven't driven that track in 40 years and I wonder how fast some turns were on modern tires Did...

David, this describes our present US city, state and national government, too Only the names and titles differ It can't last forever, the only saving grace Dennis

Hello Pete You forgot to mention "greenhouse gas," carbon dioxide that represents about 41 hundreths of one percent of the atmosphere and was about a dozen times more prevelant during one of the past ice ages (also from ice core sample data) Ain't sciencce wonderful, and politics too!! Dennis
