LCA's WON'T help as much as a Spohn TA.
QA-1, Eibach,Global West are three that come to mine.
DON'T get the Eibach drag launch kit.

 

LCA relocation brackets make a big difference too. 6 cylinder springs in the rear and adjustable shocks.

 

Thanks for the heads up

 

Having said that, though, what will you have to say when you're on your ninth or tenth 10-bolt at $300 apiece? At that point, you'll have spent a lot more than you would have paid for a nice, sturdy 12-bolt.

EDIT: Besides, do you have any desire to improve your times? Your 60' is good, but the 10-bolts really start to break in the 1.6-1.7 range. You could shave 0.3 or more off your ET just by getting out of the hole quicker, but you'd really be putting that rear end at risk with launches like that.

 

Actually The rear in this car was also in my 93 T/A that I bought in 93 and 2 months later added 3.73s (which are in it now). I think I've done fine. So you could add probably 100 low to mid 12 second passes to the tally.

I realize that the auto is much nicer to the 7.5 than the six speeds are, but a few precausions in a six speed could make it live a little longer, for instance better axels,welded tubes and a girdle support will keep the housing from flexing and eating the ring gear (which is the most common failure I see people have , along with the axels twisted.)

Also notice I said sub 1.8s I have hit a best of 1.58, but I normally hit 1.70s.

If I ever add nitrous I probably will add a 12 bolt.

Please don't think my tone combative, If I came off that way I appologize.

 

You didn't. It's good to know you've thought all of this through.

 

Let's not all forget the air!! it's horrible in some part's of the country nowaday's.. I'd say his time's are pretty good for his given mod's.. keep practicing that 60ft.. you'll notice you get out the hole better, it'll only lead to faster time's..

 

yes sir

 

Thats no joke , it's been 106 the last few days here with 75 to 90 percent humidity. Thats a good time killer there.

But like we've discussed that 60 foot with even a slight improvement would move the car into the high 11s.

 

lca brackets, if the car is lower that should have been done at the same time you lowered it. lowering the car throws the instant center way off.

lower control arms. any aftermerket are better than the stockers with the weak rubber bushings.

sub frame conectors cause im sure your vert is twisting pretty bad.

what pressure are you running the nittos at? anything over 20 psi is a waste. get them around 16-18.

what rpm are you launching at? i was able to pull 1.9-2.0 with street tires launching around 1200 rpms. i found a spot were the car would bog just enough to get it to leave without too much tire spin.

take off the front sway bar.

who did the tune. maybe have someone local look at it for you. we do all our tuning on the street in 1st - 4th gears with a portable wideband. we only use the dyno to see were we are at and maybe add a little fuel or timing but 98% of the tuning is done on the street under real world condisions.

dont put v6 springs in the rear. you want the rear to be stiff. if its squatting you are wasting energy.

 

hose it

 

Just was taking a note from someone that pulls 1.2x 60 fts.

 

joe has a ton of power thats why he is running good with them. the only reason you need softer rear springs is if you are putting a ton of power down and need to soften the launch up. v6 springs or much taller tires will both help absorb te shock.

 

Power or no power, they help the car stick. You may direct some power in a non-et improving direction, but the et will be lower if the car grabs rather than spinning. The springs do absorb the shock, but that can be the difference (static coefficient of friction) in the tires spinning or not. Basically, they absorb to make the hit softer, but after they've absorbed what they can, the power is delivered to the tires. They kind of act like a progressive controller for power. I'm not saying that this is the best way to do it, but if he wants to make the car stick without spending all of the money to purchase all of the aftermarket suspension stuff, they can work as a crutch.
