Hey

I've now have a couple of races under my belt I know how the car reacts out of the hole etc
I Just want it to get better.

right now I run a built N/A 84.5 by 89mm B20 vtec in a 2200lbs 89 civic SI
I run 23inch slicks, 1000lbs springs in the rear 550 in the front on Grond control Advanced designs shocks.
I use Hondata 300 I have my launch control set at 6600rpm and tire pressure at 10.5 psi ( before burnout)

here is a is a break down of my one of my runs
60' 1.843
330 5.200
1/8 7.913@91.17MPH
1000 10.260
1/4 12.248@113.30MPH

now I would love to get the 60' lower.
do any of you guys corner balance your cars? what % of the weight do you try for on the front end?
my tires stick out side of my fenders do you think if I flared the fron so I could lower the front that it might help?
raise launch?

any susgustions tips would help, I really would like to get her in the 11s.

thanks Justin

 

have you tried anything less ?

 

not yet
if I lower pressure should I raise the launch?

thanks For the reply.

 

i launch at 6600 and my best 60' so far was with 8 psi hot tire pressure. just keep trying different tire pressures and different launch RPM. are you preloading the drivetrain?

 

I don't use the e-brake to pre load
I've tried a couple of times and I just totally messed upo the launch.

I think I going to go on You tube see if anyone has any incar vid, of preloading.

 

Your 60ft isnt BAD. but its not the best. Lower the tire pressure betwen 8-10. Go .5psi lower at a time and see how it reacts. You'll find out where it likes it and see the significant changes. soemcars will be alright with 9psi, some a little lower. Just have to trial and error yourself.

 

That MPH = easy 11.9
I used to ran 11.9 with 110mph , 1.67 60ft.
To run 11s , you need that 1/8 mile to go down to 7.5 - 7.6 sec
Drop the tyre pressure and see how it goes.

 

so is tire pressure and launch the only thing I should be playing with?

do any of you cornerweight the cars?
