CSX3170 @Goodguys Pleasanton

[Cobra #3170]

We are qualified but not because the car was fast. We finished third behind two Corvettes both driven by past winners and good drivers. These guys are already in so we got the invitation to Scottsdale. The Cobra is 1.5 seconds slower than it was last year on the same course. The car was stuttering and blubbering all week end at low speed and never cleaned up until it got big throttle inputs. Handling was not great either we had new tires but could never get them to come in because it was cold and slippery. Top speeds were the same as last year so there is hope the car will be good when tuned correctly. We really thrashed on the suspension set up and a little on the tune, on his last run of the day Scott beat both Corvettes with a time that was 1.5 seconds slower than our best last year. Goodguys told us that the run did not count because it was a "fun" run. Oh well, at least we are in. The new engine calibration is in LB/Hr so I converted it to injector pulse width and found some interesting facts.
The new 440 cid engine has 90 lb/hr Bosch X injectors the old 498 cid engine had FAST 65 lb/hr injectors. I looked at the tables and it looks like they reduced the pulse with in full power portions of the table and left all the old stuff as it was. This means that the engine is fat as hell everywhere you are not on full power. I am in the process of reducing pulse width everywhere else now. We leave tomorrow so this is a real hail Mary deal. I think handling will come back once we get the tires to come in in hot weather on good pavement. Scott did hit 8400 rpm once and they told us it was too loud and needed better mufflers. I will let uou guys know how things worked out after Scottsdale.
