Well I finished doing my completely homemade turbo setup recently. The setup basically consists of mspnp, 440cc rx7 injectors, homemade manifold(similar to the turbotim one but simpler), homemade coller piping dump etc, ebay 550mm x 180mm fmic(matte black ofcourse) and a T25 from an R34 GTR(tiny turbo, one of the twins)
Car has 4:3 Torsen, 6speed, brass button clutch, 195/50 bridgestone adrenalin tyres. Engine is up to 230 000km with 265deg cams.
So I have got it running pretty nice just on a road tune for fuel, using katomile's timing map till a get a proper tune(thanks mate
). Thought I would just take it for a strap down the quarter. Took a couple goes to get the launch right, I tried second gear launch for the first couple runs but it bogged a bit too much after getting off the line nicely, it ran 14.0 launching in 2nd.
Tried first gear launch, and as long as I controlled wheelspin right and hit second real quick it was consistantly around the 13.6-13.7 mark. As per title best time was 13.62 which I was pretty happy with. Considering the size of the turbo and only 10psi I was expecting lowish 14.
I dont have a scanner but here is what the slip has:
R/T - 0.890
60ft - 2.062
330ft - 5.742
660ft - 8.781
M.P.H. - 82.21
K.P.H. - 132.2
1000ft - 11.425
ET - 13.628
M.P.H. - 102.81
K.P.H. - 165.46
