UPDATED RESULTS HERE: http://www.gtrherita...ction/?p=119378
Yesterday I went to the drag strip for the first time with slicks on my FBO GTR running 93oct and water-meth injection. My best on drag radias was 10.35@135mph with 1.61s on the 60'. I was ready to run faster times on slicks.
First 2 passes sucked. Worst than my previous passes on DR even while I was cutting faster 60'.
Third pass I improved to 10.29@136. Not bad, but still slow considering I did 1.46s on the 60'. I was a bit disappointed.
I self-tune my car, but I lack "track experience", so I got in contact with one of the top tuners in my area and he gave me some hints that made a huge difference!
After dialing in his suggestion, next pass i ran 10.14@136 with 1.40 60' . I was extremely happy with those times, considering I was running a cheap e85 equivalent setup (93oct and water-meth).
We decided to do another run with lower pressures in the slicks, and a higher launch rpm.
With those small changes, i was able to pull my personal best by cutting a 1.37s 60' and running email@example.com.
Things I learned yesterday:
1. Just throwing in slicks will not make you faster. You need to make adjustments to make use of the added traction. I was under the impression it was going to be a plug and play thing.
2. Knowing how to tune your car to make HP does not means you will be faster than people that do this for a living. If it wasn't for the help I got from a real tuner, it would had taken me several visits to the track to figure it all out. A waste of time and tires
3. Driving with stock front wheels and radial tires (Hankook RS3 in my case) gets a bit scary close to the 1/4 mile. With front tires pressures at 22psi is less scary, but you can still fill the back "waving" as you get close to the finish line. Its manageable, but scary.
