Last summer I completed a big turbo build on my auto HHR SS:
LDK Motor with forged pistons and rods
supertech 94# dual springs and retainers
ZZP LHU Stage 2 cams
Opel Injectors
LT1 HPFP
ATI super damper
S257SXE Turbo
MVR Actuator
50mm BOV
ZZP Manual Boost Controller
Turbo Tech Racing Intake Manifold
3 bar map sensors
ZZP Intercooler and charge pipes
Custom made air intake that's 3" pipe to a 3.5" coupler to fit the 257sxe.
Car was remote tuned, then I dyne'ed with buddy Fonse Jr from Fonse Performance in NJ. We did all our pulls commanding 3rd in HPT.
Baseline at lowest boost setting was 241WHP, 280WTQ on 17psi. We fattened up the top end by .5 lambda to get it to 321WHP and 301WTQ on 17psi. Turing up to 22psi we made 339WHP 310WTQ. This is all on 93.
This past weekend I finally brought the car out to the track, and the car falls flat on its face out the gate before taking off like a rocket around the 330. Best run was 14.787 at 107.19. Car was running 4gallons of 93 and 5 gallons of VP MS109.
Curious to see if any tables can be adjusted to get more bottom end. The car is so slow at the start everyone at the track thought I had traction control on.
Attached is my Tune, the log from the last run, and time slip.
