Yea the Yanks have shown with the correct turbo selection lag is no different than a normal set up,the turbo runs much cooler,air to intake much cooler without an intercooler,engine bay stays cooler there are some about in Aust but most are on drag cars there was a BA XR6 done in Perth a few years back but I have not been able to find the owner of it as yet,I will be a bit fussy with the air filter set up compared to most who seem to just stick a pod on the end of the turbo and fully open to the elements,as my car is used every day as a family car it has to be a bit better thought out and for that reason I will be sticking with 1 turbo and only running about 6 to 8psi boost max.
