Hi all! This is just a follow up thread to the mods I performed about a month ago. The much talked about Evosport diff.
I went out with my G-tech pro. and tore off a couple of Qtr mile runs.
The conditions: 48 degrees fairenheit. Sunny,and very little to no wind.
I did this on a very deserted highway. I took off from the right lane.The shoulder is too full of salt. We've been getting hammered with snow out here in the northeast.
Run 1- I haven't gotten used to the launching technique with the new diff. First gear is an instant tire shredder. Second is another, but when you catch traction it's like being shot out of a cannon.
I launched at 1700RPM. I nailed the gas too quick and got alot of wheel spin. pulled second gear and some wheel spin again.Shifted into third at 7400RPM. Caught traction, and hung on. Third is the money gear,It pulls
I needed to go to fourth gear, again shifting at 7400RPM.Perfect shift(AutosolutionsSSk is worth every penny)I needed fourth gear with the stock gearing as well.The result.....email@example.comMPH.
This ties my best time at Englishtown raceway.I know the car has alot more to give up. I just have to hook up better. Wheel spin is my enemy.
Run 2-I decided to launch the car at 1700RPM again, but this time carry first gear through to 7400RPM at 9 tenths throttle. Little to no wheel spin this time(that's good). I grabbed second and caught traction sooner on the rev band, Redline in second came in a blink. Third gear shift was bang on the money,7400RPM.Again, third gear pulled with 747 thrust.
BANG!, fourth gear and the run is over.....firstname.lastname@example.org
This is by far the best run I have ever seen on my G-tech.
Run 3(Final run)- Same launch RPM and shift point.Perfect!
Second gear catches with very little drama
Now the money gear again
Man, third gear is awsome
Third gear is where the power gains are felt, makes it all worth while.Fourth gear again and it's over. When the G-tech blinks and the dust settles..........email@example.comMPH. WOW
That's the fastest this car has ever gone.And it's winter and all.I know the cold air may have something to do with it, but it's a trade off. At Englishtown I have better traction, right now I have colder denser air. I don't know which has a better effect on the car. My guess is the denser air. We'll find out when we all go to Englishtown again.
My evaluation on the diff is this. There's no doubt there's acceleration gains. Both in speed and e.t.Getting back to Englishtown will tell the truth. What's most amazing is the flexability the rev range. Between Powerchip raising the rev limiter to 7500RPM and the new gearing, the speed in each gear is more useable. Fourth gear is now a great around town gear for speeds up to 55MPH. Fifth gear is great for passing on the highway with speeds up to 75MPH and sixth is now a useable gear. All in all, I lost about 500RPM in each gear which puts the RPM in a more usable powerband with in each gear.
Happy Holiday to all.
