Car looks great as always Gabe, those wheels really set it over the top. What do you think the issue is with the car?
Thanks Albert ... the idle lean condition is supposedly due to a leak ... we looked it over and saw the pcv connector going to the blower on the passenger side, is fitting kinda loosely.
I ordered the JLT kit that converts a catch can from N/A to Roush/Whipple applications, so that should hopefully fix that.
I will also check all the intake connections to make sure they're all tight.
The boost issue will probably cost me more, but maybe not.
Since my 591/505 dyno run I had part of the stock mid-pipe cut out and replaced with 3" pipe, bent at the shop (not mandrel-bent), to replace some really small sections of pipe.
Here's the new and the old, after one side was done:
So, the idea now is that those new bigger pipes, even not mandrel-bent, flow much better than the puny pipes that were on the car during the 591/505 run, and higher exhaust flow lowered the boost.
However, the guy that installed the blower was there, I asked him to check the boost sensor fitting, he took the sensor off the fitting and was able to get another full turn out of it to tighten it more.
During the dyno run above, the tuner was seeing (on my in-car boost gauge) boost mostly around 7 psi with brief peaks of 8.
I have a 3.25" pulley on the car, which is supposedly a 10-11 psi unit.
After the fitting "adjustment", I took the car for a blast and saw brief peaks of 9 psi, with most of the reading around 7-8
On the way home, leaving a toll booth, I am pretty sure I even saw a 10 psi peak, but things were starting to move rather quickly so I wasn't looking at the gauge much.
Either way, the car flies as it is, .... the tuner said that I was probably leaving with 560-570 rwhp after that fitting tightening and with the new bigger tires ... I am now looking for a boost-a-pump, a new high-flow h-pipe, new over-axle pipes, and a new smaller pulley
