There is also another thread in this forum from IMA motorsport that is working on a twin turbo for the 987 that looks pretty interesting.

I have the 2.7L Boxster which unfortunately doesn't have a hole in the middle of the front bumper which is needed to mount the center radiator and intercooler, so I had to opt for the low pressure system, but can upgrade to the intercooled system if I change my front bumper. My car had a baseline dyno of 214whp and 180wtq and with the low pressure system it brought the car to around 300whp and 235wtq. I see boost at about high 3-low 4k RPM and the car feels just like it had before with just alot more power, no turbo lag at all.

The IMA set-up is supposed to improve on low-end boost and eliminate lag, which is why all the questions, with their variable twin turbo set-up but I wonder if they are going to get the fuel map done as well as TPC.

The IMA setup definitely looks pretty interesting. Personally, I opted for TPC because they had so much experience already installing their turbo's and haven't really come across any type of major problems besides for one case that occurred overseas. I guess we'll see how the IMA turbo setup turns out.

Years ago I had a Twin Turbo Nissan 300ZX that was making crazy power and I got a boost controller from Mike at TPC to control it. There was a problem with the first device and the one he replaced it with arrived with lots of scratches--it was obviously used. Kind of left a bad taste in my mouth about his ethics.
