This is where I may argue with you. First off i do not know from personal experience, just what ive read/seen. MTW turbos are cheaper for the sizes, yes. As far as flow more air, thats a little shaky. I used to hear constant good things about MTW when they first came out, and that was basically from Adrian and his testers. Then suddenly after the PHP dyno day when they didnt perform so good, all the talk stopped! Lately, All ive heard is issues or failures. Several times Ive read people complaining about higher egts and lower boost #s after "upgrading" to a stage 1. Jaran from Holderdown also recently had a MTW hybrid go boom.
Dont get me wrong I was very interested in MTW when they first hit the scene, and still am interested but id need to hear more DD reviews. I also PMed Adrian personally to ask a question over a month ago with absolutely no reply. Id like to see/hear that these turbos are quality because it will only help us out with makin CLEAN power, but I dont know if Id throw my cash that way yet.
