on3 7681 to 475/87/1.0
well I finally made the switch to the 475/87/1.0 from the 7681 on my 4.8 csu blow through/water meth nova.. and it seems to spool about the same but makes more power.. I have had to up the jets on the carb after the cam change and now again its going lean enough to pop under boost with the turbo change... and not a huge thing but it now actually makes turbo whine with the on3 made almost no sound..
Now the car is going to get the 8.50 cage put in and the carb is going to Kevin to switch to e85.. I hope e85 is easier to keep in tune.. I almost wish it was efi..

I'm sure they do. Most budget minded people seem to like the price and overall performance they get from the Chinese turbos though. I just bought a GT45, not so much for budget, but because I've never done a turbo before. I'm positive that I'm going to mess something up, maybe after I got the hang of things I'll step into a Precision or BW.
