I have seen bad dealings in the past from other Corvette owners from this vendor.
All the years they have been selling high priced performance parts you'd think they at least knew the basics or engines and superchargers by now
Owner has a 2007 coupe with A6 paddle shifter. Stock engine with headers.
WCC convinces owner to buy a ATI KIT from them that is supposed to come with all parts needed
Owner asks about need for larger fuel injectors and is told by WCC that the stock 32 lb
injectors would be fine
Instead they sock him for more money on a Boost A pump
which is nothing more then a box that increases the voltage to the fuel pump to make it work harder. Here is the first pass tune we did results.
As seen with this street testrun with a Ease OBD scanner in record mode - weather was about 45 degrees. Again keep in mind the engine is stock
Shop owner did the testrun to 126 MPH and max of 6,600 RPMs.
Produced for that run 678 flywheel HP with 551 ft/lbs torque
You notice the tip off :
Engine knock for that run eat 452 degees of timing, each knock at upper engine loads with boost was between 5 and 10 degrees which then forced PCM to command less WOT timing to only 13 degrees.
Injectors ON time ( pulse width
) normal for part throttle is 3 mSecs.
In this testrun max ON time was 21 mSecs with a maxiumn injector duty cycle of 114%
This is with the boost a pump
An injector can only flow what it can as to its stated design, boosting the fuel pump voltage from 14 to 17 volts does not solve the problem, instead increases current and heat to pump, causes injectors to be on too long and also having more of a current load.
In sort a BAP is nothing but a workaround that will not protect a stock LS2 with 6 lbs of boost.
For the prices this WCC vendor charges for this ATI supercharger kit they should have at least the balls to include the proper injectors for as results show the average power enrichment engine loads required a 40 lb injector and maximun needed was 51 lb/hr injectors
Clearly a stock 32 lb injector is not going to support 700 flywheel HP and anyone with basic knowledge knows that.
If unchecked this owner would not have known what was hidding in that stock engine and assured over time of that engine blowing up due to how lean it would run in summer heat.
