if you can select low boost for take off then do it.
try and slip the clutch and dont mash it off the line. it takes some practice to find the balace of slip and bogging down. but best thing is to get out htere and have a go and get a feel for how your car behaves.
gtr=2 way mechanical (a-lsd v spec) 4.11:1
gtr r34= helical or a-lsd(vspec) 3.55:1
stagea= open 4.07:1
gts4= viscouse 4.375:1
(these are rear)
front is same ratio but all open.
gts4 and gtr 32 same transfer with no preload (identified by 2 drain plugs)
33 34 stagea all preloaded.(cant put on 2wd dyno)
haha. thats abit more like it
well i did an 11.3 @122 with 295rwkw on federals with a nismo tripple that was imposible to slip.(need a new diff now lol)
also worth noting was a gearset with decant ratios it has. (1st 90km 2nd 140km 3rd 185km @8k)
so 350 with a good set up should see a very low 11 if not a expencive high 10(stupid rules)
dont get a jim berry one. get one thats had alot of research and time and money invested into it. like a nismo one
and the flywheel wont explode either
