LTA's MT R vs. Zigger's GT R, and the winner is...
The stakes were high at the local closed road drag strip, pink slips were on the line! ...Actually, in Ontario they are green
Zigger and I met up last night for some gReat fun. You might have called it a mini-GTG!
Our cars: (significant differences in BOLD)
His car: Sonic Blue/Nordcap MY06 S60R GT, EST cat-back, BMC filter, BSR/PPC, lowering srpings, 18" Pegs w/OEM P-Zero 35psi?, ?? tank of Sunoco 94 gas (to be confirmed), chassis ADVANCED mode
My car: Sapphire Black/Atacma MY06 S60R MT, EST cat-back, BMC filter, Ferrita 3" DP, Aquamist, 18" Pegs with PS2's 39psi, 1/4 tank of Sunoco 94 gas, chassis ADVANCED mode
Temperature was not too hot last night at about 20C/68F for our rolling starts and 16C/60F when I did my G-timer runs.
Generally speaking we're compairing my MT with 3" DP to his GT with BSR/PPC ECU tune. We know that stock-for-stock the MT is faster than than the GT. We think the ~30hp gain of the BSR tune in Zigger's R versus the (controversial) ~15hp gains from my 3" DP make our cars nearly even. 0-60 I believe my MT has the edge and possibly for 1/4mile as well (that's IF I manage a GREAT launch which is NOT easy to do repeatedly). However, with rolling starts and highway speeds we believe Zigger's setup is faster than mine.
Further to the above and before getting into the nittgy-gritty of the G-timer numbers we found our cars to be pretty darn close from a rolling start in 2nd gear from around 40Km/h (25mph) to 120km/h (75mph). If I hit it first I could usualy hold the slight lead, if Zigger hit it first it was hard for me to catch up although I seemed to start gaining back some ground near the top or 3rd gear. Don't get me wrong, in most cases we're pretty sure Zigger's GT R did better in the rolling starts.
We used my Beltronics FX/2 G-timer which I have yet to compare to and calibrate to a real 1/4 mile track. The G-timer's accuracy between our two cars might have been marginally affected by Zigger's stiffer springs. It's probably insignificant becuase according to the manual and my estimation of how much stiffer his car is, an incorrect G-Timer pitch setting will affect 1/8 mile and 1/4 mile times buy only ~0.05s (but 60ft times should be accurate).
I had the advantage or making 15 or 20 runs before logging some really good times earlier in the year, whereas it was Zigger's first time using a G-timer to test drag-strip runs. The pics below show my best time ever in BLUE (recorded in April with slightly cooler temps of 16C/61F) and Zigger's best runs in GREEN out of his 5 total runs.
Zigger's Run #9 (Green) was one of his two best 1/4 times (both were 14.33):
Zigger's Run #7 (Green) was a really good 0-60 but he slowed up before completing the 1/4 mile. If you were to continue the green curve I think he would have beat my time of 14.00 (the blue curve). You can see how he stated to pull ahead as I shifted from 3rd to 4th. I think that's were the BSR ECU tune really starts to come alive and kick some serious butt!
You can see the biggest difference in the 60ft times, that's where the GT suffers the most due to the torque limitting, sorry Zigger
Bottom line as I see it: Through 1st, 2nd and 3rd gears a GT R with BSR tune should beat an MT R with 3" DP more times than not since the MT driver will always have a harder time getting a good launch off the line. IF the MT driver is a real pro, and likes the smell of a burning clutch, he could get ahead of the GT and stay there until the top of 3rd gear. Or, the MT driver with Aquamist can wait for another hot day of 35C/95F and kick Zigger's @ss!
Zigger plans to do more runs with the FX/2 and get some practice. We'll log some times with BSR ECU and stock ECU, I'll post those graphs in a couple days.
