My T04Z Supra

Just picked up my Supra from TDI of Thurrock.

 

After I finally resolved my misfire issue, which turned out to be two dodgy fuel pumps, thought it'd be best to get it checked over. They ran a full engine check and cylinder leakage test, results all came out between 8% & 14% which is great. Car would still stutter in high boost.

 

TDI fully remapped the car, and have done a great job, refined cold idle perfectly and the power has been properly unleashed. The HKS EVC 4 needs replacing as it only works in high mode and has a fixed duty cycle, when this is replaced and the boost can hold at high rpm, we should see over 600 @ the hubs! Eitherway, this is my track car, not a drag car. Info and graphs below.

 

Grey line - As it was when I took it in at 0.9bar

 

Blue line - Remapped at 0.9bar

 

Red Line - Remapped at 1.6bar

 

Engine Type - 3.0L Single Turbo

 

Engine Spec - HKS Cams & Pulleys

 

Turbo - T04Z

 

Intercooler - Trust 4"

 

Fuel Used - V-power

 

Injectors - Sard or Denso 800cc+

 

Fuel pump- single Walbro 485

 

Exhaust - HKS Ti 4" System

 

Transmission - V161

 

ECU - FCON VPro & HKS EVC 4

 

Mapped By - Torque Developments International

 

Dyno Used - Rototest VPA-R chassis dynamometer system

 

Power figure - 583bhp @ the hubs on Vpower (670bhp @ Fly as a crude estimate)

 

Torque figure - 510ftlb @ the hubs on Vpower (586ftlb @ Fly as a crude estimate)

 

Boost Pressure - 1.6 bar on Vpower

 

Cheers,

Harry

Great results mate. Are you happy with tdi? As im getting my car done by them in a couple weeks and they seem genuine but i dont really trust many people

 

TDi were fantastic, very professional service. Likewise, I lack the trust of people working on my cars apart from myself, too many cowboys out there.

 

Thanks for the comments folks, it's like going into warp speed when it comes on boost :D
