Let's try and guess a 1/4 time

[nando]

you need more rebound control on your rear shocks, do you have konis? crank them up!

I am running 500/front/675rears with some crap shocks until I get my re-valved bsports installed.

Just sent the timeslip over to a friend of mine who is big into drag racing to get his suggestions, he also saying that looking at the current mph if I get a better launch I might just drop into high 13s. I don't know what it will take to get a 1.7-1.8 60ft though...

[nando]

that's why it's hopping. high rates and no control. softer springs will help but it's only because your rear shocks aren't any good (although it can be good for weight transfer too)

Ok, I suck at drag racing.... lol.

Reaction 0.220
E.T. 14.748
MPH 97.275

It is very difficult to launch this damn thing, if I drop the clutch the whole rear end just hops, everything on the car is new, subframe/trailing arm bushings etc so it's not that. I tried slipping the clutch but still get lots of wheel spin and couldn't hook up 1st gear to save my life. This is on week old falken fk-452s treadwear 300 tires fwiw.

Anyways, going back next week on stickier autocross 30-40 treadwear tires and softer rear springs. It feels like it can do better with how it pulls 2nd/3rd gear but the 1st gear/lunch screws it all up.

Told you hehe dont bother going on a wednesday.You were a 10th faster than me . How did you launch I tried everything but in my case but I never did any better than when I rolloff the line in first gear. But anyways sacramento raceway is shit. you need to go when the prep the track.
A saterday race would be best

What difference would it make if it's on saturday? I mean it was hot as shit today, but is the surface that much better on the weekend or something?

First time I tried launching at about 2500rpms or so and it was pretty horrible. Then on the next runs I basically tried to go easy on it but I get wheel spin going from 1st to 2nd, let alone trying to get off the line quickly.

[416stroker]

I know what you mean. I did the same thing when I went out.

Theres no track prep on steetlegal drags they dont alow high horsepower cars there. But they have a street class on certain saturdays. When they spay the track down because of the high horsepower cars.

My guess is that you could do low 14s. You can definitely improve on the 14.7 you got.

[ed94r]

14.4@97 2.3 60ft.

I got the mph right. Good job with the short time, a 2.1 is actually pretty good for a street car, especially an E30 which is ridiculously hard to launch.

Improving the short time will improve the ET, but the mph won't change all that much. I think the general rule is for every tenth improvement in the short time, it's 2 tenths at the end, so a theoretical 2.0 60ft would be around a 14.5@97.

Good runs!

[Jean]

Ok, so was closest with their guess?

[Jean]

Specific numbers, not a general 14.5+

[ed94r]

I was off by .3 and got the mph right.

Me?

PM me your address.

Since I was there I feel the need for a slight momentary threadjack (though not really)...

I pulled a 15.56 @ 91 in a stock m20 (with 19#'s, Miller MAF, 4.10lsd), on shitty (hard as ****) tires, and in a car that probably weighs 3,150 with me in it. If not more.

So, I'm happy (cause I'm a noob, and my expectations are low) with my night. I think eventually high 14's are possible with my car.

And Jean, if you'll be there next week, just an FYI, lanes 1-2 are 'fun runs' all night. So if you feel like sticking around, you could do a couple more runs without having to do the elimination stuff.

[JGood]

and in a car that probably weighs 3,150 with me in it. If not more.

What the hell did you do to it?!

Your going to need a drag radial or slick to get the 60ft time down below a 2.0.
Did you air your tires down around 15psi? that would help hook better.
