The front of the car is generally a lot easier to work on than the rear. The job was fairly straightforward, but some parts were harder than others. Since I’ve owned the car, it has been clear that the power of the engine far exceeds the stopping power. I spent last week installing a big brake upgrade to the Sileighty. It might be worth trying to reconnect and troubleshoot the Turbosmart unit now that it is reading properly. Eliminating wastegate creep with an electronic boost controller and upping the peak boost from ~14.5 psi to 16/17 psi should see a big spike in mid range torque. Interestingly, despite feeling faster, the car is now making about 1 psi less boost and the Turbosmart eboost controller in the cabin is now reading vacuum as well as boost. It comes on boost slightly earlier, with the top end noticeably improved. With the bov hose plugged up and the vacuum lines tidied, the car is driving better. The result was not much of a seal and a leak at modest pressures. Immediately, a loud hissing was heard from near the blow off valve.ĭisassembly revealed the connecting pipe was undersized and had been padded with an extra piece of rubber hose. The idea is that any leaks will be audibly apparent and pinpointed by feeling for the air escaping or spraying soapy water to make bubbles. Safety glasses are a must in case anything pops out. I have finally identified and fixed the boost leak! After watching a few videos online, I purchased a series of pvc plumbing end caps and epoxied an air hose fitting to one that would fit in place of the intake pipe between the turbo and afm.Ī compressor was then connected and the regulator adjusted to provide 15psi.
