Well you don't 'need' one, but you know you want one :D
Definitely, requires a built engine though to unlock the turbo's full potential

Clutch is silent and doesn't feel much different to any other OEM clutch, a little bit harder but nothing noticeable and easy to pull away on the bite. There isn't really any noticeable lag, its making 300bhp at 4000rpm and pulls all the way to the redline. It's fine to drive on the road, full grip in second on a warm dry day and you can drive it around like a normal car (it is a bit noisier though :D)

I do have a few yes, I will have to start up a youtube account. I have a couple of start up, dyno runs and incar speedo

I am using Tapatalk it's free and easy, sad as most people used photoshop for their build images on most forums!

Yeah sure, done. As said, photobucket is trying to force people to pay and I dont know if I have time to go through everything, resize and reload.

Thanks, yes it comes on early and stays on close to the redline very progressively and not in a large spike, I don't know if thats just new turbo tech or the vvti head. In any case it makes these big power cars very driveable.

Thanks mate, yes, its making the same kinda power as a very strong bpu car by 4350rpm, thats impressive I think!

Yeah and also take into account the dyno makes the power look later than on the road

I've seen 800-900rpm difference in spool from roller dyno to road
