I have a Daytona 500 pace car and so far I have the PLOG with a 3" downpipe with cat thanks to ohio emissions. I want to know what kind of computer to run and which size pully. I have hear that 3800 performance and ZZP computers are about the same but just looking for some actual experiences from someone who has tried both. And which pulley size should I run with which computer.
 


For the pulley, just pick a size and see if you have knock. That's the main thing. Although minor knock can be erased once you get a tune. Assuming you're already knock free a 3.5 would be a good start.
 
I live by the Weymouth Country Club on Route 3. And I dont have any knock at all right now but I was hoping to get down to a 3.0 pulley but I wasn't sure if I have to get a cam or rockers by that point. I know it's just a crap shoot with the pulley size but my last one was 345whp and that was a 2.8 pulley, pcm custom tune, full borla 3' exhaust cam and rockers, and all the supporting mods. It ran 13.0 pretty consistantly at Dragway 42 but it kinda sucked daily driving. I wanna be somewhere inbetween that and where I am now.
 
If you want a 3.0 pulley, you need a cam and intercooler. I have an XP cam and only run a 3.2. For your current set up, I would say start with a 3.6.
 


Drag 42! I've been dying to go there, but never got a chance to this Summer. But yeah, if you want a 3.0 you better be ready to shell some more $$$ out lol
