I inquired about this setup some time ago in order to stay relatively compliant and trouble free within my state. I would had liked to go with a legit custom grind or a PD cam of some sort, but my hands are/ were mostly tied if I want to keep the car registerable. Fast forward to now and here we are. LT4 has been fitted with the DOD delete cam and the benefit of a 32% fuel lobe and we are up and running! Car seems to like the cam for the most part. I'm trying to figure out my limitations, however, and while I'm rocking a 5% overdrive lower pulley I have a 12% from when I first got the car. I used to run 27* of timing at WOT, but with this new setup I backed it off to 24* as per the advice of someone who helped me set up my tune initially at the time. I don't know if that is/ was necessary, however. I'm also trying to determine if it's even worth running a larger pulley if it's going to exceed the 20,000 RPM limitations of the supercharger drive idler bearings. Would someone be willing to take a look at my tune and tell me how I'm looking and entertain all of my new curiosities regarding the setup?
Mods are as follows:
- Flex fuel (currently E50- E60 before running overdrive fuel lobe)
- JMS BaP
- 5% ATI supercharger pulley (12% on standby and ready if need be)
- Secondary cat delete/ full exhaust post primaries
- Granatelli SS wires
- LT1/5 cam with 32% lobe
- DOD delete
- Katech oil pump
- Heat Range 7 95605 NGK Ruthenium plugs
- Cordes LTR reservoir
- Water Wetter
