I'm gettin a set of BF goodrich Drag radials from my buddy for dirt cheap, i plan on using them till i get a set of actual slicks
my car's a 87 TII with S5 TII motor and tranny, I dynoed 313whp 289ft-lbs last year i did a few things over the winter should be atleast 325whp now,
has solid engine and tranny mounts, mmr subframe and diff mounts , welded front diff mount, strong clutch type TII LSD , and OS Giken twin disk

i went to the drags before i went to the dyno last year i was only runnin 13psi and got 13.2@108 and a 2.12 60ft on some kumho supras 225-50r16, i never got to see what 15psi dyno tuned would do

the drag radials are almost new 225-45r17 on steelies (not really what i wanted, but meh)

what rpm launch would get me the best 60fts with the drag radials with out breaking anything

i was getting pretty consistant 2.1 60fts with the kumho's at about 5-5500k launch they didnt prep the track it was pretty slick before

 

I would scratch the radials and get a set of et streets or similar bias ply drag tires. They will absorb any wheel hop and also give you better 60's! Guys are getting 1.5's all day long on stock suspension FD's.

 

If ypur gonna run them anyway drop them to 17psi and try launching at 6000rpm, ive run them with a best 60ft of 1.72.

 

Don't drop the hammer on radials, you'll either break **** or spin. I would try a quick slip from 6k.

 

thanks for the reply's guy's , around 6k would be good i think , but my OS giken twin disk, doesnt let you really slip it lol
my cars such a dog off the line though my 330ft are where im losing alot
my goal is an 11.99 when i get it up to 350whp in a couple months the car weighs 2520lbs im 165lbs
here's some video from when i was running the 13psi,right now im about 50+whp more than here, i had turned the boost to 15psi and tuned it on the dyno a few weeks after

After watching you launch you werent leaving with much boost if any, you need that 6,000rpms and your clutch doesant slip becouse your tires suck. If you have sticky tires then you can raise the rpms and slip the clutch to keep the r's and boost up! You might even need to go higher but its a start!

 

thanks for the help!!!
