Default Trackspeed Stage 2 VVT shortblock, CNC head, EFR6258, E85, 300whp/264wtq@16psi

Motor:
  • Trackspeed "Stage 2" shortblock
    • 83.5mm Supertech 8.6:1 piston w/ thermal coating
    • Manley H-beam rods
    • ACL Race bearings
    • ARP head/main studs
    • Boundary Stage 2 oil pump
  • Supermiata CNC ports
  • Supertech +1mm valves
  • Supertech SUB lifters
  • Supertech heavy double valvesprings
  • OEM BP6D cams
  • OEM VICS manifold
Turbo:
  • Trackspeed Turbo Kit w/ BW EFR6258 0.64a/r
  • Precision 350hp intercooler
  • prototype Trackspeed IC pipes
  • custom 3" exhaust
EMS/Fuel/Ignition:
  • MSLabs MS3 Basic w/ CAN Wideband
  • Innovate LC-2
  • GM Flex Fuel Sensor
  • Injector Dynamics ID1000 (82%DC max)
  • Deatschwerks DW200
  • OEM BP4W fuel rail
  • OEM NA6 FPR (43.5psi w/ reference)
  • Fuelab 818 filter (6ppm Fiberglass media)
  • pump E85 (~77.5% ethanol)
  • OEM VVT coils
300whp/264wtq at 16psi peak. Made a little more on the pull before (304/268ish) but I backed the timing off a couple degrees for safety. 16psi at 5300, bleeds to 15psi at 6600 and stays there. It made 270/244 at 13.5psi and 286/255 at 15psi, so there is lots left in the setup even breathing through a VICS manifold. The low-boost can that is required to make the 200/220whp maps possible means there's a little less boost from 3500 to 4500 then there should be, and peak boost is limited as well. I probably could have squeaked it out to 18psi with the boost controller nearly shut, but there was no reason to go further. The goal was a 300whp kill-mode map, we got there easily.

Beautiful torque curve!

A glimpse into my future, minus the E85. Nice!

Amazing numbers. This makes my plot look gutless before 3700rpm.

Nice torque Trackspeed! That's got to be a beast on the track.

For guys with streetcars who don't necessarily need the track-abuse durability of a fully built engine on ethanol, would your setup on a stock VVT longblock and 93 octane pump gas map produce a similar dyno graph, all other components being the same (same intercooler, exhaust, appropriately sized injectors for pump gas, etc)?

Are you willing to share dyno files? For comparison purposes

I mean I would expect a $5k head to work magically.

To compliment that head add some higher lift cams with just a tick more (10 degrees) intake duration and that HP will climb to redline instead of leveling off. Should hit 350whp at the same boost/rpm level.

Looks great Andrew! I now get the earlier 6258 recommendation. Will 99 head alter the curve drastically?
