You will struggle to get the 350 faster than a R35 GT-R.
I have both and as soon as I get close I up the power on the R35.
The problem that I have been having, is once you get up to 600-700 bhp at hubs with the RWD 350, traction becomes a huge issue.
However to combat this, Syvecs 6S+ has been fitted with a traction rotary switch to control/select different tyre sizes and different weather conditions, so hopefully that will do the trick.
