Ok, well, finally, we are just about to wrap up our turbo kit. It has officially been released and taking pre orders. We are going to shoot for the record stock block power today which I believe stands at 420whp, but we might just do that for corny bragging rights. Our provided tune will most likely keep it around 400/400 for reliability reasons. Here is a dyno of our turbo kit, compared to our complete stage 1 package (intake, downpipe, cat back, intercooler, and tune) Both runs are on 93 oct pump gas. The car is still on the factory fuel system as well. As you can see below, there is no question that the stock turbo makes much more low end grunt, but does fall off up top. That is where the 5858 takes over. These runs were done on a journal bearing 5858. I would imagine a BB could see up to 400rpm quicker spool. Sorry, the stock turbo run is kind of hard to see due to the lighter lines, but hopefully you can get the idea.
Here is another run from this morning that I took with the old cellular telephone. This one you can see RPM a little better.
