The 80 4.9 TurboTrans Am Pace car is still there.

yikes Drag and Scott, that is a bit rough for me. Also a bit far away. I will keep looking.

Motorsport Ranch in Cresson, or Eagles Canyon? I bet Jimmy Johnson was testing for the upcoming 24 hours of Daytona race. The Gainsco team with the red #99 Daytona Prototype that he runs with every year for the 24 hour race have the shop next door to mine in Lewisville!

Matt,

Answer from my business partner below.

Lynn

Hello Lynn,
The track is at Cresson, about 12 miles from my house. Try http://www.motorsportranch.com Go to the site, and look at the Gallery/Media tab, then click on Streaming Video, then click on the 1.7 mile track counter clockwise. The car is turning laps within one or two seconds of what my Corvette turns, about 1 min 27 seconds. The site is pretty descriptive, and as you can see there are some pretty good cars. If you come out you can use my membership to get on the track on most Friday/Saturday and Sundays, with an orientation from myself or another club member. You can get lessons for only 60.00 per hour, from the club pro....you can even get instructions from Johnny Rutherford. Fridays are very lightly attended and generally work out well for new drivers. I have rented the open wheel cars, which is also pretty neat!!
Hope you can make it sometime soon.

It's great to see your progress Lynn. This is for sure a major undertaking to say the least. The the question begs to be answered. Are the two versions of heads that you are designing slated for a street vs. strip designation?

mike

[NHRASuperStock455SD]

Mike,

Our biggest focus is for street/strip applications.

There is enough material in the castings to pretty much port as much as you want. This allows the racing guys to do what they wish.

Lynn,
What is latest pertaining to delivery date of the water jacketed heads?
Jim

Jim,when my heads are avail they are going direct to you.Tom

Going there tomorrow, will update this weekend.

Jim,

We are doing something I believe to be unprecedented. We designed a single port based on flow models. No biggie there. However we have cast two versions of heads. One with water jackets one without.

From a guy who has spent significant time on porting a set of heads, please tell the Pontiac community what limitations during porting did you have due to the location of water? How much, where, and maybe overall % loss (guesstimate)

We have found that the stock RA-V heads only have very thin walls for porting in some critical areas. Sometimes around 0.100 of an inch. This also makes the head susceptible to cracking due to heat. I have had 5 sets of RA-V heads stock and 4 of them were had cracked.

Our plan is to:
*sonic test all ports for porting thickness
*port non-water jacketed head to optimum
*port water jacket head and compare
*evaluate for wet flow
*redo areas needed in tooling to make adjustments
*dyno for combustion efficiency (time/temperature/turbulence)
*redo

This will be followed by a continuous improvement method. Plan => Do => Check => Act. That is, as improvement opportunities arise.

Lastly, we are doing 2 more critical things:
1.) Developing a quality control program
2.) Tony @ BES has just received a new CNC cylinder head machine state of the art. We will incorporate several things as options: (to name a few)
*CNC port program
*port matching program for OEM(stock) castings
*Intake machining for cubic inches, hood height requirement, overall porting
*Combustion Chamber size CNC option

Please Jim your thoughts.

Ok, I cant be the only one drooling like a rabid animal waiting for more info here...lol.
