The rundown
07 roush stage 1
L&m built 4.6 stock bore and stroke
Stg 3 comp cams
Mild port on heads
Twin gt500 pumps w/jms fuelmax 52# injectors
2.3 whipple @18#s
Jpc intake w/ l&m twin 72mm tb
Sw long tubes into straight pipe w roush mufflers
Steeda 10 rib belt kit
Stock heat exchanger, stock ic res
Tr3650 spec stage 3 clutch
Bought the car in November it was built by stanghi and last summer made 604/589 but the car had driveability issues. So I decided to have it retuned by JMS, initially they told me the car needed more fuel and one of there jms fuelmax should take care of the problem. The car got the fuelmax and retune and made 580/57x, at first I wasn't to happy to hear but I brought it there for driveability issues. After speaking with Monte he informed me that the car was running lean which is why they added more fuel and also said my 2.3 whipple is being overspun by 8000rpms. The car would run out if fuel at 5800rpms before jms tune and now the limiter is set at 6400 because the belt started slipping. The car feels the same power wise but can drag the gears out for a few secconds longer, I understand this blower is extremely heat soaked and was wondering if going to a one size smaller pulley would help the car? The car is daily driver and I was racing a buddy of mine and it was obviously pulling timing in the 90* south LA wether but I just feel like this car runs the same power wise with more fuel delivery. Based on the mods should this car be making more power? Is there any mods that need to be done to make it run better? Just looking for some input. Thanks
