Yesterday I took the 2.5 hour trip down to Mason Dixon Dragway to get some runs in with the 07'. Not many GT500 folks push the factory Eaton supercharger, as planting a TVS or twinscrew under the hood is the more typical choice. Wanted to take the road less traveled and see if I could get a modest Eaton setup into the 10's at the strip. After getting in 17 runs over 4 years, (with 7 of them being aborted due to missed gears with the factory shifter!), finally hit the goal. Got in two runs:
1) 10.937 @ 126.92 w/ 1.658 60'
2) 10.963 @ 125.75 w/ 1.575 60'
Unfortunately, pissed away a decent 60 foot and a shot at a 10.8 on the second run with having to deal with some squirreliness in 2nd gear.
Basic Setup:
Posi Ported Eaton w/2.40" upper pulley (14.5 lbs of boost)
VMP 67mm TB w/ LM Plenum
JLT 123 CAI
3.73 Gears
J & M LCA, Roush UCA
MGW II shifter (of course!)
MRT Catless H Pipe
MT 15 x 28" Slicks, M & H Skinnies
Notes:
- No long tubes, no lower pulley, no injectors/BAP, minimal suspension mods, and modest weight reduction, (for me at least....will outline in another thread). Just don't have to break the bank to get decent performance.
- Slicks are obviously big here. High torque, poor basic front > rear weight distribution, often require more non-bias launching skill. Plus slicks absorb more of the shock at launch. Less breakage.
- Only 20 guys have hit 10's with the Eaton according to my research. 81 Terminator guys have done it. My experiences would actually suggest that it's a bit easier/less expensive with the GT500.
- The IRS is a challenge with hard launching with the Terminators. The shifter/transmission on the GT500 can be a nightmare.
- The GT500 M122 is bigger and more efficient than the 03/04's M112. Obviously..... But have a much harder time keeping the M122 cool than the M112.
