Well I have to say that I am with Silva bullit on this.
My car has run a half court low at many a autocross, the cars been run at high RPMs all the time I cruise around at 4k just to here my exhaust(besides the cars are worthless any lower) I have no problem as of yet.
Now I did take your advice scott and I am running a 1/2 high.
But again I just looked at the blowin engine thread and although I think it sucks that it has happend to these guys, the truth is there is only about 20-25 posts on that thread!
This site has over four thousand registered members. Thats pretty good odds, imagine how many have viseted and never registered. I would bet had they had a blowin motor we would have heard from them.
Perhaps it is a problem but it does not look to be on a mass scale.
