Got Tenagah Motorsport to organise one of their new ZAGE external 38mm gates for me. Quality of the part was excellent and the fit and finish in my car is awesome. The quality of the workmanship on the uppipe can be seen in the pics. Hisham has more pics which he is going to email me.
The feel of the car is much improved even in an untuned state as I can now hold 20psi to redline instead of the 15psi peak boost I was getting which dropped to 10psi by redline.
The external gate has removed boost leaks from the internal gate and I now do 100kph with about 300 less revs. The boost at low speeds is now fantastic and I see 5 to 6psi fairly easily even with my big turbo.
The Gizzmo IBC holds the boost really well with a variance from 19.7 to 20.4 on a setting designed to give me 20psi. Very steady boost.
If you want a very solid upgrade to your car then get this done. Even on a stock turbo the improvement in the feel of the car and its ability to hold boost even at high revs will be awesome. Low speed boost will also be increased if your internal gate is openning up too early even by a small margin.
Overall a 10/10 mod....and its not even tuned yet!
