I accidentally posted last night results in the FPevogreen thread. With new dyno readings, shift points are 7200,7700,7700. Poor track, more torque, more wheel spin = ultimately, same basic time 11.31 before 11.35 last night, (before being kicked out for not having a roll bar and jacket) We'll fix it and go back. MPH in general was better with cam timing change up top. Best trap speed was 122.97, 1/8th best speed was 96.7 I think, best time with new MIVEC was 11.41. Changed mivec back to old settings, speed dropped, but recorded best time of the night at 11.35. Go figure??!?? Still need to get traction issues resolved before we know what the engine is doing. NO 1.6 60's last night, mostly 1.8+

Yes I definitely think your recommendation on the mivec changes helped. Since the launch is 6469 and following those loadcells/rpm, should the settings still remain the same, or would the lower load cells be different than the higher loadcells? But MPH was absolutely higher. Your recommendation on the tires was actually exactly one of the last settings we tried before going to 20/20. At that point was when I lowered the 2-step to 6150, tires at 20/20 and we bogged (may have been a little slow on the clutch release), but I upped the 2step and got the final 2 times, 11.41 then 11.35, still bad 60's.

Another point to note, no way to get to the starting line without driving through the water. Low level trench area holds the water, so you have to go through it just before the line. First pass or two had water AT THE LINE area. Over exuberant track official on the early passes of the night. Finally, 10pm, good conditions, good air, getting a grip on the situation, then SEE YA.

This is my son's car with the 20LT, so I'm assuming you're talking about it. It only has an HKS 272 exhaust. Stock intake cam, stock ECU, stock head, stock intake manifold, stock TB, and just changed the stock DV out for a Forge RS. Still have a lot of room for improvements.

Just some comparisons and observations on time vs speed. After reviewing as many of the whp/wtq's posted and then comparing those to their times/speed, here's what appears to be a pattern: MOST of the cars with low mph vs their et's have higher torque numbers (some greatly) than whp. In those higher wtq vs whp cars, their times are noticeably better than similar cars who have higher speeds. Here's a list of cars and their times for you to compare:
???(forgot sig) 10.869 123.87 (2.8mph faster than OKIX 11.31/121.03)
dragnracing 11.147 @ 123.97 (2.9 mph faster, only .17 time diff)
topspeed 11.1?? @123 (2 mph faster, .1??-.2 time diff)
Ihuntv8 11.2?? @ 122 (.1 time diff, +1mph)
madmat 11.3 @121 (same exactly)
fimotorsports 11.4 @119 (-.1, -2mph)
The thing about ALL of these cars, is they have better times, than anyone around them that have higher mph. They also appear to have higher wtq than whp. Many are IX's. These cars are on the fastest 11 list for a reason and comparing or looking for mph doesn't tell the story. They obviously know how to drive their cars, My point is that two tuning philosophies exist. Higher number whp, higher mph's doesn't always equal lower et's. Remember this IS the drag racing forum. Higher WTQ, at the expense of some whp yields lower mph, but in these cases, lower et's too. Look at the list and compare by mph, you'll see it too. It also appears that this pattern holds true for some of the tuners and their results. This is not a bash of anyone or anything, only an observation of wtq/whp and results. These cars listed are proving that high mph isn't needed to get the low et.
