Well, you'll need more than just another mod. What do you run now? Have you taken it to a drag strip? You may need that new head that ZPI is putting out.

You need an exhaust.

You're pretty much in 14's territory right now if you can drive, nailing a 2.2 or better 60'. You SHOULD be a consistent 15.0-15.2 @ 90-92 with the mods you have now.

Get seat time.... and tires make more of a difference than a flywheel. Tires are the #1 mod that everyone forgets about, but make all the difference in the world.

 

I did a test run on my blizzacks the other day when I had them mounted and balanced on my stock rims for winter time that was some embarassing stuff right there, winter tires with the sealant still on them, first and second were a JOKE lol... any who back on topic, yeah tires make a huge difference, stay away from Nittos, BAAAAD traction...

 

Whoops, Sorry folks, I just double posted I believe. I put a similar question above.!

 

* I didn't go to a drag strip yet but with a G-tech i've a 1/4 mile of 14.85 @ 96MPH
* Which ones are the best tires for street cars that stick good on the road

 

better subtract like 4 mph and add .1-.3 seconds to that quarter lol... those things are somewhat closebut nothing for bragging rights

 

If you put the car weight in correctly, then they're actually close enough for testing purposes.

I agree though, a dragstrip and a timeslip are the only way to verify, but usually Gtechs can get within +/- 0.1 second and +/-2 mph.

 

bf drag radials will get in the high 14 sec definatly and they are street tires
