Hey guys, this might seem weird, stupid, strange, etc.. BUT, what do you think about getting all the drag racers here and for the calendar year of 2008 having a contest to see who can have the LOWEST ET? No limitations on mods (not much anyways). The participants can all pitch in like 20 bucks and the winner take all? We'll just have to be honorable... but timeslips with pictures/videos would be required (or validation by another member).

Heck, I'd gladly pitch in 20 bucks to see an IS-F get into low 12's. Oh, another rule... No payout unless the ET is lower than 12.4 seconds!

If interested, I'll start a list of participants:

1. ToothDoc
2. caymandive
3. dkaplan435
4. DRE1615
5. HKS350

Ooh, now the pot is $100 bucks!!! - but I'm starting to think lower than 12.4 is gonna be pretty tough.

btwanky

this would actually be really fun......

DRE1615

I think that would be really fun. However I think a sub 12.4 second timeslip is almost unachievable. I've yet to see or experience a 60' of less than 1.9 seconds. All my 60' times are 2.0 or higher which will finish me off with a 12.8 or higher. From what I have come to believe, and correct me if I'm wrong, .1 second in the 60' equates to .2 seconds less at the finish line. So we would need to be pulling 1.8 second 60' times at least to make a 12.4. Maybe that IS possible, but it will definitely be challenging.

You also might want to add that dashhawk ET's are not applicable. I've seen plenty of bogus timeslips and recordings from Dashhawks that are way off, way low to be more specific.

But all in all, good idea. Now, anybody want to donate any tires for this "event"???

Does it have to limited to IS-F's? I think I can run with you guys. Should do all 2IS. You could ask a Mod of the fourm to hold money in a paypal account for the winner.

There is quite a bit to be gained simply from temperature/conditions and engine breaking in. My IS350 in the first year had a best of 13.8 fully stock and a year later, I was doing 13.2 fully stock by simply launching better, going on a cooler day, and probably the engine breaking in. My launch went from 2.0x to 1.9x but my overall time dropped over 1/2 second!

I don't think anybody drove their IS-F in 40 degree weather yet with the engines fully broken in. This spring, there were only a few IS-Fs and they were mostly NEW.

Caymandiver already has 12.5x and I already see him going down to 12.4x with even better conditions.

BTW, I've been doing some research for rear drag radials to fit 18" rims and I can't seem to find an appropriate size - anybody find 255 40 18s?

255/40/18 is almost identical in height to 255/35/19 so there will be no gearing advantage, but it would make for more consistent and better 60' times with traction. FYI.. Hoosier R6's are available in this size.

I've already tried my old setup with 245/35/18s and they were just small enough in diameter it was causing an extra shift right before the end of the 1/4. So that size is definitely out. 265/35/18's would probably work fine, but they may require a wider wheel.?

ToothDoc

I didn't actually want to decrease outer diameter hence the 255 40 18 (26" diameter) plus I recall your previous experiments with the smaller tires leading to an extra shift...

I wanted a dedicated drag tire in essentially a stock size in hopes of getting into the 1.8s or lower possibly.

I am also interested in reducing rotating weight as much as possible. Anyways, here are my plans to break into 12.4 or lower:

Remove spare, jack, engine cover, remove windshield wiper fluid (hey, that's good for a few pounds). My KEY mod will be the lighter rims. I plan on running in Oct/Nov only when the temp is lower than 45 so I can hope to get a DA as close to sea level or even below if possible. If it's 70 degrees, I'm not even going to bother going.

My lightweight rims are 18" actually. Looks kinda crappy - especially because I never got the center caps.

BTW, can I count you in James?

HKS350, I personally don't have any objection to you running your 2is (is it 50 shot? or LMS supercharger?)

Also, for the IS-F guys, there is that SRT intake and chip that gives like 20 HP...

I'm not sure if it's true or not, but I even read that Vishnu tuning has a chip also for our car - I don't believe it's for sale yet.

Ooops yeah I forgot to add that in my previous posts, but yes you can count me in.

ToothDoc

12.4 STOCK is probably almost unachievable, BUT, with the little bit of modding that is available at this time, I totally think it can be done. Low fuel, low wiper fluid, lighter battery, lighter rims and tires, remove spare and jack, intake, a/f computer, exhaust. I think those mods alone will take those of us trapping 111 to about 117 mph and drop the 60' from 2.0 down to 1.8. I honestly believe with simple mods, we'll be in 12.2-12.4 range this fall/winter. Another little trick (I'm sure all of you know anyways) is to short stage.

DRE1615

I'm probably going to wait until next spring to start modding. But I'm definitely in for this little competition.

Toothdoc: It was nice "meeting" you the other day for the whole 15seconds. PM if/when you head to GLD or wherever. I'll tag along for sure. Or even if you want to go cruising.

Well thanks, Its a 65 shot. With the 330whp and close to 400lbs of tq at 3000k with good traction I can't see why I can't pull 1.6-1.8 60' times. 13.0 1/4 without N20 = 2.0 60' ft times. 1.6 60' = 12.4's

The tranny will prevent a really good 60' due to the torque converter engagement off the line. Ideally something like what the muscle cars have to power off the line would be great, but not sure if that's even possible for our type of tranny. Some kind of stall converter I believe they call it. I think even with those great numbers you are putting down that it will be nearly impossible for anything better than a 1.8x 60ft.

HKS350

The only reason I'm going to disagree is from my experience with the old 1st gen IS300. 394whp (on the first turbo setup) stock tranny/bone stock and I pulled 1.7 60' times using a 50 shot to spool off the line. I ran 12.4 -12.5's all day long. But I did have a lot more peak HP tho. IDK... Frist I need to start with tires, then we'll see. Your probably right.

ToothDoc

So, HKS350, I'm putting you in. BTW, I just got back from GLD and I did a baseline run today. Fully stock and PS2 tires. No weight reduction, 1/3 tank of gas:

60' are: 2.026, 2.069, 2.007, 2.025, 2.020, 2.000, 2.041, 2.041
1/4 et are: 12.890, 12.989, 12.912, 12.939, 12.888, 12.907, 12.914, 12.987
trap are: 111.24, 110.81, 110.93, 110.90, 111.31, 110.78. 110.87, 110.36

Temps are 54 degrees and runs were at 7:54 pm to 8:36 pm at GLD. 29.94 inches Hg, dewpoint 42 degrees. DA comes out to be -219 feet so I'm pretty disappointed at my trap and ET. However, the runs were pretty darn consistent. I should do some bracket racing!

On the very last run, which I didn't include, I had a passenger and he said he weighed like 135 pounds. My ET was 13.1 and trap was 109.xx. So, I'm going to approximate that every 60 pounds or so = .1 seconds of ET.

HKS350, FWIW, I got down to 1.91x on my IS350 using stock tires (kinda worn down to like 6/32" tread). I actually was able to launch my IS350 better than I ever could my IS-F so far. I could consistently hit 1.9x and right now, I'm hitting a consistent 2.0x on my IS-F. I attribute that to better weight bias on the 350 and softer suspension allowing for more squat and weight transfer.

I also did 4 runs break-torqueing today and 4 runs just mashing the gas and guess what? I have no statistical difference between the two. I also tried running in sport mode and regular mode and guess what? No statistical difference again. I KNOW that manual shifting is faster so I didn't bother with auto shifting.

Last time I went, I went on a poor day but my tires and rims were not stock. I'm pretty sure the rims and tires alone are good for about .3 to .4 seconds!

Next time I go, I'm going to put back the Volks and RE050s. I didn't break 2.0 at all today while with the Volks and RE050s, I averaged mid to high 1.9x and that was with a +2000 da and I still ran 12.8 average vs. today's 12.9 average.

I'm also going to remove the spare and jack this time for a possible tenth.

BTW, I ran a corvette convertible and he did 13.733@102.51 and I also saw a supercharged ford mustang (cobra?) and he didn't once break into the 12s.
