  1. We should change it up to the Mustang FR500S for 2020.
  2. I forgot to share some pictures from our race weekend at Gingerman. We plan on doing 3 races next year, Gingerman, Indy, and Road America in the fall. We plan on doing a lot of testing between April and August. We will also be renting seats in 2020 so PM me if you're interested.
  3. Not to hijack the thread, but since Ray is participating, I'm going to ask. How are factory spoilers scored? Did this mustang get an additional 10 pts for its factory spoiler?
  4. I made my own, not bad for my first try. I did brake one of the louvers and had to have it welded back on.
  5. I use a 2006 2500HD with 6.0L gas engine. It gets around 8 mph with the 24 foot trailer, the Fatillac, and all the stuff for the race. I would like to go back to a more towing friendly tire now that I don't drive this in the winter anymore. This truck just rolled 90k, is long paid for, and is in great shape. My plan is to find a nice used class A diesel pusher motor home if I plan on doing races further away.
  6. Thank you! Radium's products and customer service are 2nd to none. They are also always developing new products too. I'll be upgrading to there new discriminator vent and adding an overflow that exits externally into a catch container.
  7. We put our cell in a 1 inch by inch square tube frame and then covered the frame, top, and filler.
  8. A little late, but here is our 1st and 2nd stint from Sunday. I had camera issues on Saturday (like forgot to turn it on). This was this drivers first ever wheel to wheel race, so he eased into it. Here is the 2nd stint on Sunday before the lunch break. This was my first wheel to wheel in over a year so I eased into too!
  9. I agree. Mike Chisek walked by and saw it and said the same thing. He explained that it look as if it took a large shock all at once and came apart. The one chunk still has all the paint stamp on it. The other side of disc was like new. We ran 7 hours on Sunday with a new clutch and no issues. On a positive note, I did find out that I can use the single mass flywheel conversion for a fifth generation Camaro 3.6L on my car. I only found this out because of the research I had to do to find a clutch on Saturday.
  10. I get it. That’s why I’m going to try again but as long as the rings are good I’m not touching the bottom end.
  11. I should also add given the way the clutch failed (blew apart and was not worn) I’m thinking that money shifts may have caused everything.
  12. It’s an LY7 and the red line is 6500 rpms. It was assembled by me with the supervision of a 30 year Cadillac tech that has re-ringed hundreds of these engines.
  13. Timing chains are known to stretch with this engine, but was due to lack of maintenance or to long between oil changes. This was more of a GM oil life issue than a customer not doing their maintenance but most people didn’t bother check their oil ever and after 8,000 plus miles it didn’t need an oil change, it needed oil!
  14. I got a lot of crap during my build from fellow Champcar racers for letting to much air in to the engine. I have another engine that needs timing chains and a right cylinder head due to timing chain issues and bent valves. I've got enough parts between the two to put a working engine together with new chains.
  15. I have a good idea of what happened after reviewing the data. I have not had a chance to talk to the driver about it and I'll leave it at that. This was a fresh build and only had 13 track hours on it before it stopped.
  16. We have the engine torn down and have found all the destruction. It appears that we spun 4 of the 6 rod bearings sending metal throughout. The timing chain idlers have an oil passage that feeds oil up through the middle of the idler. Both idlers where contaminated with metal causing one idler bearing to start to fail and have a lot play. This then caused the main timing chain to start moving around breaking some of the links in the chain but not all the way through. Those broken links started digging into the chain guides wearing through the plastic and into the aluminum causing even more metal to go through out the engine. This is my theory. This is metal that got past the filter and into the timing solenoids.
  17. I do recall hearing about a driver being badly burned and I'm so sorry for what your family has gone through. I'm curious to know more about what happened in the interest of knowing what I can do to help myself and my team be safer. I always thought it was ironic that someone had to be seriously hurt or killed in Motorsports before rules got changed, but I guess you can't always predict what could happen until it does. @Snowman if you prefer to not discuss the event on the forum publicly or not at all, I completely understand.
  18. First off, that is not a pizza oven or a wood burning stove in there. I had already removed the back seat and package self structure before the "everything must be enclosed in metal" rule came out. We had hopped to install it where the back seat was, but it was to tight to get the cell in with the cage already installed so we mounted it above the rear axle in a steel frame bolted to the frame of the car with grade 8 hardware and wrapped fuel cell cage with sheet metal. Enclosing the cell was not a big dealer, but enclosing the fill tube, vent tube, and fuel filler pocket overflow tube took some work and wasn't complete until the Thursday before Gingerman after a few failed attempts with different ideas. We ended up using 5 inch semi exhaust tubing for the filler tube cover and had no trouble passing tech. Our fuel cell is roughly 8 inches higher inside the vehicle than the factory tank that was under the car, behind the rear seat bottom, but in front of the rear axle. This didn't seem to causing any crazy handling issue at any fuel level. The weight distribution is 51% front, 49% rear, with driver and a half tank of fuel. The bad: We had only ever filled our car without the fuel filler covered so peaking in the back window and watching for the fuel to come up the filler was the way we new to stop. Our fuel cell vent runs up along side the filler neck and then back down and out of the bottom of the car. It was never a problem filling the car, and we never had any issues with fuel coming out during or after filling once we hit the track. After enclosing the filler with metal we could no longer see when the cell was full and quickly learned on Friday when we filled the car for the race on Saturday that this was a problem. I started filling the car and heard the sound of liquid hitting the ground, but it wasn't coming out of the filler neck, it was coming from the vent. It appears that once the tank is full that it fills the vent line first then the filler tube. This results in roughly a half of a gallon of fuel spilling out of the vent. This is when I learned the difference between a roll over vent valve and a discriminating vent valve. We made some modifications to our vent and relocated the hose to a safer location to easily catch the over flow during refueling and lived with our situation but it was not ideal to have a half a gallon of fuel leak out even if it was into a container under the car. The everything must be enclosed in metal rule: What brought this on? Did something happen that caused this rule to be added? Like many others have said, this seems to make servicing and inspecting fuel lines, filler lines that much tougher. If you can't service or inspect the lines easily and the line fails fuel is still going to leak somewhere, maybe not inside the vehicle, but somewhere. How long is that fuel going to leak before its noticed? If its not inside the car, it's outside the car and probably near something hot. As stated above, our likely hood of spilling fuel went up 100% during fueling now that we can't see that the tank is full. Added a port hole with the approved fire resistant lexan isn't going to let enough light in for us to see that the cell is full either. My other concern is that 5 inch metal tube and what happens when that side of the car takes a hit in a car to car collision or a roll over? I can't help but think that steel tube is going puncture the top of the tank and cause a larger leak than if it was just the filler neck popping off witch is going to happen anyway with or without the steel tube. I'm all about a safe race car, but to me it seem that this rule could potentially be more dangerous than the way it was before. If anything, maybe remove the filler neck needing to be enclosed and add a mandatory fuel filler discriminator valve for cells inside the drivers compartment? What's next for us: We plan on adding some type of quick connect overflow solution to the rear of our vehicle and rerouting our vent line so that overflow is minimal and contained in the overflow container. I did a lot of research on fuel cells and installation before finishing our car and felt that there seems to be a lack of information for our particular series on how to do things the correct way, safely. I would encourage tech or someone much more knowledgeable than myself to add some diagrams for proper fuel cell venting to the rules page. Maybe a document on how to prevent overflow and spillage including accurate descriptions of parts required to make your fuel cell safe(er) could be added to the web page like the how to pass tech sheet was.
  19. I have a screen. Believe it or not, the fins looked like that out of the box. The rest of that are bug chunks.
