by not loosing my stereo? Each sub I have weighs about 35 lbs (I have 2) and not to mention theres 3 heavy amplifiers as well and I do not remove my spare tire either, because I am lazy. I would have to say there would be at least a 100 pound reduction if I got rid of just the 2 subs and spare tire. My last trip to the drags ran me at a 15.0. I want to break into the 14s very badly! Ontop of that, all the weight is in the rear of the car, so I'm sure that is not helping off the line traction, being that my car is not even lowered. My 60' was 2.3 on that 15.0 run.

I wonder how my 60 foot times would be affected if I had stiff suspension (coilovers :-)), poly motor mounts, high friction clutch and the LSD.

Well, I took mine out. It consists of 2 10 inch subs in a box, a piece of wood in the trunk floor to hold the box, 2 amps, the spare, the jack, the tools. I also ran on about 1/16 of a tank of gas instead of almost 1/2.

My times went from 16.1 to 15.8 with no other changes. So yes, it makes a difference.

Yes, your stereo is slowing you down some. Pulling the stereo and spare will probably get you into the 14s. You've ran a 15.0 at what mph? Trap speed is a good indicator of how how quick your car really can be. That extra weight on the back probably gets the rear fairly flat on launch. Once you remove it, there will be a lot more weight transfer which will induce more wheelspin. 2.2 60 foots take a lot of practice if your track isn't prepped too well. Try launching at 4000rpms next time. Be gentle when the car gets rolling and then quickly release the clutch and feed it gas. You want to stay above 3000rpms. If you drop below 3000 then you'll bog and your 60' will stay in the 2.3 range. I use to launch at 2000rpms and would spin then bog. Then I got crazy and launched at 4000rpms and I got spin, but the car never bogged. I went from 2.35s down to 2.25s and well into the 14s. Stiff suspension, poly motor mounts, high friction clutch and the LSD will help launching somewhat, but your skill is what makes the most difference with tires coming in 2nd.

I do not have the time slips infront of me but I do remember it was in the 92 MPH range. Since that time I have a Stillen B pipe on order (oh yea, I was running with a leaky Cattman Y pipe as well). I got crazy too and I think I was launchin in the neighborhood of 5000 RPM. You're right it does take some practice but I never redlighted and I had great reaction times. Next step is to fine that fine line between fastest clutch release and minimal wheelie spin. I also used to launch low and the engine would bogg down. Also I remember when I ran that 15.0, I shifted it at 6,000 RPM instead of winding it all the way out in 1st gear. That too will make some difference cause we're only talking 1/100's of a second to get me into the 14s. I wish I had a 1/4 drag all to myself and perfect my drag racing methods!

This is roughly how it works...for every 100 pounds you take out of the car you will run .1 faster in the 1/4. Atleast that is how it is in my car.

every 100 lbs = one tenth of a second has been the general rule, but I personally think it's more than that. I think about every 50-75 lbs equals a tenth.

So you'd have to remove about 1500 lbs from your car if you wanted to run 14.8. A real 14.8...

Dave B

It's all relative to the torque and size of the motor. On big and healthy V8s, the .1 for every 100lbs is pretty much accepted, but on lower torque producing V6s and especially I4s, the weight becomes more an issue. I'd say 100lbs dropped off the Max will improve et by atleast .15 and with a Honda well over .2. It's all relative.

I live in Cololrado. I do my runs at aprox. 4900-5000 feet. I went to a website I will give you if you ask where it corrects for sea level under OPTIMUM conditions. These conditions hardly ever occur. If your mad because I put my corrected time I'll put my real time up after I have my Supercharger installed. Will that make you happy?

Your sig is too big. Why post every mod on your car?

1/3There2/3ToGo

Why post them?! Why do them if you dont post them? I do it to bother people that find it annoying. If you dont like it, dont read it and scroll past it.

Why dont you just post what you actually ran? What's so hard about that?

Are you embarassed? You shoudlnt be, all stock auto maxs are slow...fact of life. I'm damn proud of my 15.8. It was faster than any other import out that night.

SB97MAX

Just let him post his sig, I mean isnt that what this board is all about? To show off your Maxima and what you have done to it. I understand how you feel about really really long sigs but its not like they waste that much time scrolling down. Take Care

1/3There2/3ToGo

Its not that Im embarassed, I know auto's are slow. Mine is the fastest in my town, second fastest overall in my town. I just dont feel the need to post it as well as the corrected time. If it bothers you that much I'll add it to my sig, but I've been getting some slack that my sig is too long, and that truely means nothing to me...but its just anoying. Anyway, if you want me to add the real time I will.

SB97 - I'll shot you an email later tonight to set up a day to do the SC install. And thanks for backing me on my sig, I too believe that that is why we are all here. I guess some dont, oh well.
