Today I tested one of those "Junk chrome 36HP shrouds" and it beat everything we have tested so far, including my shroud and the DTM!
I blew my oil cooler on the dyno 3/4 way through the run so I'll have to back it up tomorrow. The cell temp was already up to stable, and the humidity had dropped so things were flattened out. The extra 5 min of run time probably would have shown no difference but I need the numbers for averages since its so close to the stocker.
I'm still out to beat it, but its pretty discouraging when what is thought to be the worst, ends up being the best so far..
Before you ask me where I got it from, all I have to say is this sucker is getting a few small mods to make it better and I'll be selling them! I gotta get something out of this huge investment that has so far proven my shroud not to work very well........
Since the stock shroud is doing so good look for an upgrade kit to come from all this testing for it... Just a few rivet in deflectors can REALLY make it hard to beat!
