Hi all,
MattyS4 sent me a text with a timeslip today. He is having traction problems with the amount of TQ from his set-up and his PSS’s not giving him good accelerative grip (I actually concur with him and have stated in the past that the OEM Dunlop Sport Maxx GT’s gave me more consistent grip), ran in mid 80’s temps around 2960ft density altitudes…
He runs the usual intake, exhaust, LW wheels and more. His tune is an APR stage 2, stacked with a Chipwerke Pro (4-1 setting), APR DSG (he has short-shift, and the usual APR shift hang-up issues as well), APR’s 57.75mm s/c pulley, and his Kustom Import 194mm crank pulley; overall pulley ratio is 3.359. He was running 94 octane, and methanol injection in order to run APR’s RACE program.
His best time today is 11.3x@ 125.76mph, with a 1.64 60ft time nonetheless! That’s trapping 1.51 mph higher than the Magnuson stage III car that ran in negative density altitudes! Plugging in the numbers, if he ran at near 0 density altitudes, he will run 10.6-10.8@128-130mph (possibly higher in mph).
3.0"T" development is coming along nicely with me, MattyS4, OneAngryBunny, mrmommo313, and blownone taking it up the limits with running larger cranks than JHM’s 179mm or GMG’s 180mm.
