Auto Gears In A R33 Manual For Drags

[Pal]

Hey all,

I done a conversion on my r33 a few years ago and have taken my power level up to about 330rwhp on a highflowed turbo) the only thing left that is auto is the diff. went to the drags a couple of weeks ago and managed a poultry 13.466 at 108mph with a sad 2.372 60ft. my nephew who has 270wrhp ran the same 60ft ran a faster mph as mine and got a 12.91 (on stock turbo) . would the auto diff be causing the problem? these cars have been set up on the same dyno so power levels are comparable.

Auto diff should be the same strength wise but be 4.33:1

Should be helping acceleration and not hindering.

i would have thought that to Adrian but it doesn't seem to be happening.

It can also promote excessive wheel spin.
