  1. Today my wife said, "You haven't heard a word I said, have you!" I thought it was a strange way to start a conversation.
  2. I didn't realize that the Secret Service had to tailor their training for each president to make sure they got the response they expected in emergency situations. With the last president they had to avoid yelling, "Get down!"; with this one they can't yell, "Donald, duck!"
  3. The other day my wife said, "Could you get me a bookmark?" Thirty years of marriage and she still can't remember that my name is Dennis.
  4. Back when I started in autocross, updates and backdates within a chassis generation were allowed with no points. One could pick a vehicle that had been produced for a number of years and cherry-pick all the good stuff to build a car that had all factory parts but hadn't been available as that combination. Biggest fuel tank, lightest chassis, most hp, best transmission and/or diff, best suspension, hubs, rad, brakes, etc. For Champ, that list includes using the heaviest curb weight for swap calculation. More freebies for the high VPi cars with no benefit to the low VPi cars that already have surplus points and nothing to use them on.
  5. If the 3515 lb curb weight is used, your additional points are 154. Having fun doesn't depend on your points total.
  6. It's been an ongoing topic on the forum for at least two years. I personally have brought this to the attention of BoD and TAC members on more than a few occasions to an effort to prevent someone building a car using the bogus weight in the swap calculator and getting caught in a no-win situation. You have the dubious honour of being that person. Blame it on the people who should have taken five minutes and corrected a number in a table.
  7. This page tells a different story: http://www.supracarparts.com/tech_data.html Heaviest non-turbo model has a curb weight of 3515 lbs. 90% of that is 3164 lbs. Your build is why I feel that it is very important to get the VPI and swap calculator standardized. You now have a car that is either: 1. Allowed to have a 260 hp engine in a 2700 lb race weight car for 54 points. That's 10.38 lbs/hp, compared to a 2300 race weight E30 with 189 hp at 12.17 lb/hp, a 17% advantage. Or: 2. An EC car. If it's EC, you just put a lot of time and money into something that you wouldn't have built if the correct numbers had been in the tables.
  8. Wasn't sarcasm but the truth. The power brakes and power steering on the Fiero make for decent feel but low fatigue and makes the car feel light on its feet. No sore shoulders or legs, and I usually hop out after a stint. The half-spin that I did at Portland in which I got nailed was with the slow manual steering, and I changed to the quick ratio rack and power steering before the next race. I probably would have caught that slide and continued rather than letting it go and attempting to roll off the track. I didn't try to save it because of the high potential of doing a tank-slapper from being so far behind on the steering from the slow ratio. One of the more significant improvements I made to the Fiero and I recommend it highly.
  9. Just send that extra two gallons of capacity to me and we'll both be happy!
  10. Basically an old NASCAR spec for the fuel vent line. Not sure why it got added to and still remains in the rule book.
  11. What's the point adder for one of these? https://www.amazon.com/SRP-Steering-Quickener-Long-Style/dp/B007IIWHUI
  12. Be thankful you didn't get charged 40 points for adding power steering like I originally did for the Fiero. I felt it should be 10 points for non-OE component (yeah, I know, that was for suspension but...) but then was surprised when it became zero because driver comfort. The power steering rack that I swapped in place of the stock non-power Fiero rack is a 2001 WS6 quick ratio box. Low effort yet great feedback and of course much easier to catch a slide when it's only 2.2 turns lock-to-lock vs 3.0 stock. Driver comfort? You bet, and a nice performance bonus with a fresher driver at the end of a stint, not to mention knowing that one can push the car harder for the whole stint with less risk of a spin.
  13. I'm kind of surprised that there's a concern about cars that have a high speed differential but have to make more stops for fuel. That's exactly what I've been told to do with my Fiero, and the rules have been changed to encourage that concept. I have more than enough points left over to significantly increase my PWR at the expense of shorter stints but don't see any sense in going so much faster than everyone else that I would essentially be racing only the clock.
  14. I raced against a guy that brought a Hobby Stock out for a 3 hour enduro race. He lasted about an hour before he blew up.
  15. Weight is listed at 450 lbs but I haven't weighed it. And it's a Pontiac engine and was only available in the 1st Gen Firebird. Sorry, can't have it in a Camaro. And thanks, I'll contact them!
  16. Just an update, ran across a video of one of the pulls: And as an interesting aside, this engine with the mods as tested in the video (cam, carbs/intake and header) would only add 125 points to the 100 base VPi of the 6 cylinder first gen Firebird that it was available in. Just imagine, a Champ-legal car with an 8.6:1 PWR and 20% more fuel than a 200 point Fox-body Mustang ...

  18. We timed everyone when practicing our "on fire"' driver exit; kill switch, pretend to pull the fire handle, drop the net, undo the belts and open the door. I was quickest at just over 10 seconds, average was 15 seconds.
  19. Sound attenuation from directing the exhaust at an angle into the ground can be 2-3 dB by itself.
  20. And I don't think you'll find any. By the time combustion starts the bulk of the effect from vapourization will have occurred. From that point, the homogeneity of the mixture will play a bigger part in the combustion process. Typically a stoichiometric mixture will have the highest flame speed, while mixtures on either side will be slower so pockets of less-than-ideal air/fuel mix will slow down the flame front. To make the most power, excess fuel is introduced to ensure that all the oxygen in the intake air is consumed. It also has a cooling effect from the vapourization of the excess fuel and can be a significant factor in controlling temp rise during combustion.
  21. The temperature of the fuel can be a factor but in general it is a small part of what's happening. When fuel is introduced into the incoming air, it's atomized but not fully vapourized. As it turns from liquid droplets to a gaseous form, that phase change absorbs energy. This same process (phase change) occurs in your air conditioning and is what is used to cool the air. Done correctly (ie, strategic placement of fuel injectors), this cooling effect can be used to increase the density of the incoming air/fuel mix and make more power. The closer the fuel is to its boiling point, the quicker it can go through the phase change, but one has to be careful with carbed engines not to boil the fuel in the lines or the float bowl. EFI can have the fuel temp much higher because of the high pressure lines. I haven't personally done any testing with fuel temps. Direct injection uses very high pressures to both drive the fuel into the chamber against combustion pressure and to much more finely atomize the fuel, resulting in very rapid vapourization. The flame front is more determined by the leading edge interaction of the fuel spray with the surrounding oxygen than by the flame speed of a homogenous mixture, good because the pressure and temp rise in a standard engine would quickly exceed the auto-ignition point of the mix and cause detonation. By controlling the flame front with the fuel spray, 87 octane can safely be used in a 11.5:1 engine. Note that a SIDI engine will have more oxygen in the intake charge because there's no fuel vapour displacing some of the air. That plus the increased compression ratio usually gives up to 10% more power just by itself over a conventional EFI engine.
  22. The band, not necessarily the city. Enjoy! P.S. Don't watch if you think Russians who don't speak English aren't worth listening to. ;)
  23. An old blind packers fan wanders into vikings-fan sports bar by mistake. He finds his way to the bar and orders a shot of whiskey. After sitting there for a while, he yells to the bartender, "Hey, do you wanna hear a viking fan joke?" The bar immediately falls absolutely silent.In a very deep, husky voice, the woman next to him says, "Before you tell that joke, sir, I think it's only fair that you should know five things since you're blind."1. The bartender is a vikings fan with a baseball bat.2. The bouncer is a vikings fan with a Billy-Club3. I'm a 6-foot tall, 275-pound vikings fan with a black belt in karate.4. The man to your right is a vikings fan who is a professional wrestler.5. The person to my right is a vikings fan who happens to be a champion weight lifter."Now think seriously, sir... Do you still want to tell that vikings fan joke?"The packers fan sits and thinks for a second, then shakes his head."No, not if I'm gonna have to explain it five times..."
  24. This is only for the Norwegians, the rest of you are not allowed to read this! Ole was stopped by a game warden in Northern Wisconsin recently leaving a lake well known for its Walleyes. He had two buckets of fish.As it was during the spawning season, the game warden asked, "Do you have a license to catch those fish?"Ole replied, "No, sir! Dese here are my pet fish.""Pet fish?" the warden replied."Ya sure, you betcha." answered Ole. "Every night I take dese fish here down to da lake and let dem svim around for a while. Den I vhistle and dey yump back into der buckets and I take dem home.""That's a bunch of hooey. Fish can't do that." Said the game warden.Ole looked at the game warden with an expression of great hurt, and then said, "Yumpin Yimminy! Vell den, I'll just show you den. It really does vork, don'tcha know?""O.K. I've got to see this!" The game warden was really curious now.So Ole poured the fish into the lake and stood waiting. After several minutes, the game warden turned to Ole and said, "Well?""Vell what?" responded Ole."When are you going to call them back?""Call who back?" asked Ole."The fish!""What fish?"
  25. A better selection would see your points go through the middle of the peak efficiency island and likely start closer to the compressor surge/stall line on the left. That one's a little big from what I can see. As an example. this one seems to have lower boost capabilities, with the island extending down to the 1.4 bar range (5.9 psi). I'm sure our local turbo expert will arrive soon to educate me (please!) on the plethora of modern choices.
