Vw Corrado G60

My Supercharged Karmann Vdub

Here you can see the Engine Tuning Mods & Spec of my Volkswagen Corrado G60. Detailing boost return, chip, exhaust, injectors, intercooler, pulley, supercharger, throttle body & more. Images [117] are in chronological order and may show changes over the years. You can view the or ask a question by leaving a comment.

The engine of my Corrado was near standard when I bought it except for a superchips ECU chip, a slightly smaller pulley and a jabbasport chopped supercharger belt tensioner. It didn't stay like this for long as you can see from the pictures.

One of the first modifications which is popular on the Volkswagen G60 engine, was to remove the boost return pipework from the G-Lader supercharger and intake system. This stops dirty, warm air being fed back into the supercharger, the reason for this OEM setup is to recirculate emissions.
It is falsely believed that when doing this modification, you need to spray PTFE into your supercharger. Please don't believe this rubbish, there is absolutely no need. I then decided to port, polish and shape the throttle body. I'd never seen this done before, so thought I'd give it a shot. This improved responsiveness.

The next major upgrade came in the form of a PSD ported, polished G-Lader. A smaller 68mm pulley and an SNS stage 5 antilag ECU chip. These gave a great improvement in power and torque! And you can see this via the rolling road power graph image below.

When it came to upgrading the intercooler, obviously it needed to be front mount (FMIC) but I wanted to try something different, so a sierra cosworth 4x4 intercooler was integrated into a front bumper cutout. See more on the Exterior page. After a cylinder head and injector rebuild I had the Corrado rolling roaded, and you can see that the supercharger, chip, pulley and intercooler gave a great improvement in power and torque!

Since the rolling road session I've added a few more of the usual G60 performance parts and modifications. BBM RSR supercharger outlet, New Red top injectors, Porsche 3.5bar fuel pressure regulator (FPR), a Magnex exhaust system and a home made twin cone induction kit!
