Old Project Revitalized - 56 Track Car

now I do feel old, there's an "old" school carbon? do they hang out on a carbon forum and grump about those 'kids' these days?
 
Here is another project moving along slowly. I am finishing the buck for my hood - working on symmetry and finish sanding. I will pull the carbon skin off the top of the buck to leave exposed carbon fiber on the bottom (underside of the hood) and will add one layer of fiberglass on top to serve as a "sanding surface" to prevent the CF from printing through the paint. Then I will bond the skin to the inner frame.

Pappy -

Details as you have time - please. You said;

Are you pulling a vacuum on the lower hood section with the CF - or doing all open layups?

The yellow tape is suspicious as if maybe doing a vacuum - that is why I ask.

Your skill with making these 2-part assemblies is very, very good. This hood will be awesome - and no weight at all. You are making me re-look at some of my pieces that are "dense" and thinking I need to revisit some. Thanks for the "challenge"!


Cheers - Jim

Hey Jim,

I vacuum bag small, complex parts, but for the hood (and roof), I will do open lay-up using rollers and squeegees to clear any air bubbles and reduce the amount of resin in the finished product. It will be a little heavier than vacuum bagged, but not a lot. I use vinyl ester resin for the parts that have a fiberglass outer level for paint purposes. Epoxy resin does not work with fiberglass. I use epoxy for anything structural. The yellow tape you see is just to establish lines for symmetry measurements. Here are some photos of wet laid and vacuum bagged parts:

Panels behind the grill to complete a pre-radiator diffuser. They were all vacuum bagged. The small wing (in the middle) goes behind the grill center bar and may provide some downforce, but is mainly to divert more high pressure air up higher on the radiator.

I know BBShark won't like my thumbnails. If someone will tell me how to make the photos larger I will start doing that. ?Brake Duct Molds.jpgBrake Duct 3.jpgGrill 1.jpg

A Viper track buddy of mine and I bought 6XD sequential transmissions at the same time. He has his on track (I still have a ways to go), and it works like a champ. We track at Inde in Wilcox Arizona, and last week he beat the NASA TTU track record by six seconds! Here is a video of the sequential in action you may like: [ame]https://www.youtube.com/watch?v=imifL0iQ1e0[/ame]
 
It fit. Also, notice the changes I am making to the roof - eliminated the 1" tall header stainless to try to cut down some drag.

i need to add some WOWs!!! very nice
 
+ WOW! [How soon do we get to see it on the DYNO?]

My MoTec tuner is working on calibrating the DBW throttle, and Brown and Miller is building oil and fuel lines as I send them specifications. Things move slow. The motor was on an engine dyno for break-in after it was built. Cutting it off early (6800 rpm) and with a fat AFR and only 34 degrees of timing, it made 852 hp and 685 ft/lbs torque. My tuner thinks it will eventually make closer to 900 hp, and that should be close to 800 whp. Probably enough.
