16.3@90

[SHO-NUF93]

I imagine the trap speed is what really tells the tale here. This was my best run of two, my first time racing the SHO. I know what really killed it was my launch, as evidenced by a 2.9 60'. RT was .505(this track uses a system where .0 is a perfect RT) The 1/8 was 10.8@70, and that ET is alittle disappointing, since my wagon went 10.6@66, although I was not afraid of beating on it.

My whole deal was I was told that burnouts **** diffs. So when I launched, I rode the shat out of the clutch. My first run was much worse, since I also missed 2nd, and ticked off a 17.3@87. But now, from what I read here, some wheel spin upon hard launch is acceptable. And so I find comfort in the trap speed. Maybe next visit to the track will be more 'fruitful'.

For those curious, the only mods to the car are a Dynomax catback, stock y-pipe with gutted cats, and a cone air filter.

Practice makes perfect, I ran my car the first time in 2005 first run I did was a 16 something. I took that all the way down to 14.5. Getting good 60's isn't easy but will help big time with your times. It is said that a 2.2 is a good time to get. 90mph should get you in low to mid 15s I would think.

2.9 60'

Are you going through the water box or somthing?

90mph isnt a good trap speed at all really.i assume your at or near sea level right?
ive got close to 100 passes in 4 diffrent SHO's at Orlando speed world
stock trap speed should be 92 or higher,with just a Y-pipe and a catback i was getting close to 95 im my 3450lb 91.

The 60' time was because I launched at about 4k(what I launched my ****** at) and rode the clutch, big time. I heated the clutch up so much that my 1-2 and 2-3 shifts were very soft-the clutch had no harshness to it at all. In addition, my ricer excuses are that I drove the 70 or so miles to Gainesville from Jacksonville in the car, on two dry-rotted front tires, one of which was showing cord on the inside, with no spare tire, and was afraid of breaking the tranny, since I've only owned it for 3 weeks at the time, and was unsure of its history.

I now have some marginally better tires, but hopefully those will be replaced before my next track visit. And dropping the 60' .5 or so should not only drop my ET a second, but should more than likely yeild at least an extra 1 or 2 mph on the big end.

practice on the street somewhere where the cops won't give you a hard time.
then when you figure what feels the best take that setup to the track and use that as a base line.you will have to tweak it some due to the sticky track surface.but with some practice you should be able to get at least 2.3-2.4 60' no matter how bad your tires are

How do you figure that?

Well, it should be approximately a second. They say for every tenth you drop from the 60', 2 tenths come off the ET. So, provided I can 'still' drive, at least a 15.5 should be doable.

Sounds like you already know where to make the improvements

In case you didn't see it yet:

Generally speaking yes, dropping a tenth off your 60ft time will take around two tenths of your 1/4 et, so yeah, if you drop down to a 2.2 (which is about as good as it gets for an MTX SHO on street tires) you'd be looking at a high 14-low 15, with 2-3 more MPH on the trap, which is right where a healthy MTX should be

The diff issue I think is more related to high rpm clutch drops where you have one wheel smoking away. An aggresive drag strip launch where you're getting some minor wheelspin I don't think would be much of an issue. But I'm not an engineer, so don't quote me on that

First time I went to the track this summer, my first one was like 16.5 and the second one 15.8 but with a trap speed of 95mph and still a ****** launch of 2.7. So practice is the key. I just can't wait to mount my summer tires on and go back on the track when it opens up (mainly because my sister beat me by 0.011 seconds with her B-18 with gsr tranny CRX)
