Can't really say that they are not some what biased. Afterall centrifugal superchargers take a long time to spool up and have serious lag. They also seem to be stuck in a turbo world of only oil cooled units. The srt-4 turbo or almost any mitsu turbo for that fact as well as most BB turbos are oil and water cooled. In such a case oil baked to the turbo does not become a problem. They obviously have not seen a reverse rotational twin scroll turbo before because they would not say a s/c produces a broader powerband over a turbo. The stock or stage 3 turbo produces full boost at around 2700rpm's and has max torque from that point on. No surge on either turbo's. It seems their comparison was modern technology superchargers vs. dinosaur technology Garret turbo's of 20+ yrs ago. Turbo efficiency has come along way. Hope you guys don't take this post wrong but I do feel they are a little one sided. Some points I agreed w/ but tunability is not any harder on a turbo than on a s/c if you know what you are doing.
Yes indeed they did but they never said a centrifugal s/c takes just as long to spool as a big turbo. I have seen many Novi S/c and paxton s/c dyno and all centrifugals seem to be the same, LAG MONSTERS!!!! Just thought it was funny that they attributed lag to only turbo's for the most part but yet they do mention centrifugal s/c but do not mention them being just as laggy as a big turbo.
They were not bashing turbos at all but I just thought after reading it the second time, that they did have a little bias in there. Totally understandable coming from a supercharger.com site. Nothing new. I am sure if anyone went on any turbochargers website they would get a fairly accurate comparison as well but it would not be w/ out a little bias either.
I saw a shootout between a turbo and two different types of s/c's installed on the same car to see what the difference was. The turbo made the most power and passed the s/c's in hp and tq by 3000rpm's. The turbo curve was by no means more linear than one of the s/c graphs but it made more power throught the majority of the power band. I think it was honda tuning or modified magazine that did the shootout but I really can't remember. It was about 3 weeks ago that I saw it. The other thing is there are lots of company's making very reliable turbo kits for all kinds of applications such as AGP. Like I said, a little bias but nothing that you wouldn't see on any other site supporting their products and trying to be as unbiased as possible.
