<p>[QUOTE=&quot;Dr. Jeff Harper, post: 1024887, member: 22311&quot;]My 2 setang worth:</p><p><br /></p><p>So . . . . I was at the Bangkok Drag Avenue last Saturday night for the big &quot;Re-Opening&quot; of the track.&nbsp; Everybody was talking about the new facilities, the new retaining walls, the added length of the shut-down area, and all the other new features.&nbsp; But most of the conversation was about the racing surface - was the track going to be as good or better than before . . . or worse. Everybody had an opinion, which they are entitled to.&nbsp; My opinion was that no matter what the track owners do, a &quot;green&quot; (new) drag strip needs to have a large number of race cars race on the surface before it &quot;comes in&quot; (makes good traction, or &#039;bite&#039;). That being said, the racing surface was nice and smooth, they &#039;rubberized&#039; it by dragging tires across it, cleaned and washed it, and sprayed it with VHT traction compound.&nbsp; All in all a very good effort. </p><p><br /></p><p>The first couple of cars had a difficult time getting traction, but as more cars did burn-outs across the line, the traction started to get better. As the night went on, and more and more cars made hard passes, the strip got even better.&nbsp; My observation was that some of the cars, including the high powered dragsters, were able to find excellent traction (on the new cement), while other cars struggled to&nbsp; get traction anywhere. Why was this?&nbsp; Was the track &quot;bad&quot;&quot;&nbsp; My opinion is that &quot;NO!&quot; the track is not bad.&nbsp; If it were bad, NO cars would be able to get traction.&nbsp; What we saw on Saturday night was a&nbsp; case of cars with drag slicks (greater contact patch) and/or suspensions that allowed weight transfer &quot;at the hit&quot; of the gas pedal were able to get traction and run very well.&nbsp; There were several Ciferos with 2JZs and 1UZs that made excellent full-power runs without wheel spin, while other cars could not find any &quot;hook&quot; at all.&nbsp; </p><p><br /></p><p>The cars that could not find traction should use this as an opportunity to learn about their cars&#039; set-up: does their chassis work (there is weight transfer); do they need to adjust tire pressure or starting line launch rpm; do they need new (softer) springs in the rear and 90/10 drag shocks in the front? Or . . . just be patient for three or four weeks until more and more rubber is laid down in the racing &#039;groove&#039; of the track and their cars can again use tire rubber (only) to get traction they were used to.</p><p><br /></p><p>Any new track, no matter where it is, takes a little time to mature&#039; to &quot;come in&quot; to a state of seasoning.&nbsp; Please do not be too quick in judging this track . . . is already good . . . and it will be excellent very soon.&nbsp; Be patient.</p><p><br /></p><p>How good is the racing surface now?&nbsp; Well, my race car (Harper Racing Familia) has a very good chassis set-up that gets excellent traction anywhere and drag slicks. . . .&nbsp; actually broke the diff (rear end ring gear) on a hard &#039;back on the wheelie bars&#039; launch last Saturday night! The track is and will get stickier further and further down track as more and more race cars go down it . . . . and when the owners spray the&nbsp; last 1/8 mile of tarmac with VHT. I think some racers have forgotten how &quot;bad&quot; the old surface was when it was first opened (green).</p><p><br /></p><p>We are fortunate to have such a high quality facility to race on here in Thailand, and we have the owners to thank for that.</p><p><br /></p><p>Racers:&nbsp; be patient. This track is as good as almost all of the tracks you will find in the USA or Australia where they are all this smooth.&nbsp; All the tracks in the USA and Australia needed time to season - have alot of race card go down the track under power - when they were first opened before the traction became great. BDA is already&nbsp; good . . . and it will become excellent soon enough.</p><p><br /></p><p>Work with your combination: you still have to tune your chassis and tune your engine . . .&nbsp; it is not all a matte of how sticky the track is . . . . and most importantly: tune your engine and chassis TO THE TRACK![/QUOTE]</p><p><br /></p>
