  2. Trailer queen. The Zoomie pipes are still nice and shiny without any discoloration (unless they are fake).
  3. Call Ross http://www.rosspistons.com/ and talk with Mark Degrath. BTW... don't run any top end lubrication on a high compression engine. Its a pretty quick way to burn up a piston through detonation.
  4. Yes. The shift took .65 seconds (measured from acceleration peak to acceleration peak) which translated to .3 seconds at the end of the run. The faster run had the car on the rev limiter for about 3.5 seconds.
  5. The Koni shocks Classic Garage lists for the S30 are no longer available.
  6. That's what I said and didn't believe it until I saw the data from a couple different cars and drivers. The data acquisition guy did an overlay of the same driver upshifting and not and at the end of a 65 second course the difference was that one upshft. Its not just the shift, its the time between lifting off the throttle and being back on the throttle. The downshift doesn't usually matter if you're good at heel/toe because ideally you're braking while downshifting from 3rd to second.
  7. Its always been my favorite car and this new version (except for the red decals) gives me yet another Porsche woody. One day...
  8. 70 mph in second is good. Per the data collection I've seen, a perfect shift costs .3 seconds on an autocross course.

    n42 head

    I got one on an N42 block. There's an ad for the N42 block and head in the Parts for Sale forum. http://forums.hybridz.org/showthread.php?t=151873
  10. As you can see, I take my baseball seriously.
  11. With 45s you're can easily make 250hp with the L24. Spend your money on some 12 to 1 forged pistons, good head porting, large valves, and a 300+ duration cam. Source the rods with the 9mm bolts and spend money on reconditioning them and making sure the crank is in great shape. New Nissan rod and main bearings, turbo oil pump, and a good sized oil cooler will make sure it lasts for a while.
  12. $21K for a hood on a Shelby GT500KR? $632 for hood pins? Not surprising since its something from the greatest automotive huckster of all time. http://www.spokentorque.com/forums/showthread.php?t=1517
  13. Your might be correct regarding rebound. If cut cut off the wire ties holding the spring to the upper and lower seats you might find the noise goes away. Also, check the gland nuts and make sure they are tight in the strut and are tight on the shock.

  15. You guys are missing one of the primary diff mount failure modes on a high horsepower S30: The diff cross member cracks and the single stud on the mount tears out of the cross member. Making a stiffer mount will only exacerbate the issue by transferring more bending loads to the cross member's sheet metal. Stiffening the mount is not the solution. The RT mount solves this problem in a very simple and elegant way.
  16. Check the gland nut holding the shock inside the strut, check the upper insulator mount.
  17. C'mon! There is no batter in baseball that intends to hit a pop fly or fly out.
  18. Cheating is basically intent and there are three judges on that intent: You're own, your competitors, and the sanctioning body. I'm a national level scrutineer for SCCA road racing and we catch people all the time not meeting the rules. The vast majority of these folks are not cheaters, they've made a mistake. Last weekend at the double regional at Buttonwillow there were two perfect examples of cheating and just making a mistake. After the qualifying session for the open wheel cars one of the Formula Mazda's came across the scales 11 lbs. underweight. The driver and crew chief both admitted that they made a mistake and under fueled the car for the session and accepted their grid position at the back of the field with grace. No one in Tech thought these guys were cheaters, they just made a mistake. A Formula Ford driver had 6 water bottles in his lap as he came up to the scales and was chugging down the 7th as fast as he could. I asked him to hand me the water bottles in his lap and he said no, he was overheated and needed to cool down. His wife and crew chief both agreed and said he was in danger of heat stroke. I said I'll radio for the ambulance. All three said, "No." I then asked again for the water bottles and they handed them over. That car scaled in 8 lbs. underweight. At that point their arguments began - "Unfair", "He's the fastest anyway and should start up front", "Its just a regional race so why are the car being weighed", "Your scales are wrong", "Its only 8 lbs." Those folks were cheaters.
  19. IMHO, I would run the 240Z kit (1" front and 3/4" rear) over any of the other ST kits. Its a better balanced setup and the rear sway bar mounts in a better position then the stock location for lowered S30s.
  20. I would leave too if she took away my bacon! Straight to Denny's and order me a big 'ol Grand Slam!

  22. There are many things that contribute to vehicle stability. PMOI is just one aspect of that and can be tuned for or against with springs, bars, tires, etc. A low PMOI car is not always a spin waiting to happen and a number of high PMOI cars can span spin pretty easily (think short wheelbase 911). When PMOI makes its presence known is when the suspension is mostly taken out of the equation - as the rear tires lose all grip and the yaw rate increases. Quick hands are needed at that point in a low PMOI car. Also, comparing a F1 car (or any other open wheel, purpose built race car) to a production sedan is an exercise in futility. And being scared of a car spinning during an autocross or a race is a sign of driver inexperience or poor chassis setup. More seat time and a good chassis setup will allay those fears.
  23. NHRA rule book section 19 - Participant Conduct Rule 19 has been used many times before.
