Need a Power Vision Map for 117"
Need a Power Vision Map for 117"
I have purchased a 117" motor for which I will need a Power Vision map. It has 10:1 compression, 2" intakes, 1.65" exhaust, Drago's 580 cams - intake 20 / 42 .578 lift 243 duration @ .050; exhaust 44 / 18 .568 lift 243 duration @ .050. I plan to run the stock 50mm TB with stock 4.3 injectors for now, it does come with a SE TB. I will run a Drago's 2:1 exhaust with the 2.55 collector. If there is more information needed let me know and I will provide it if I can. I would like a map that is close enough that auto-tune can bring it in and make it right.
I am going to ask FM if they have a map that will work, I just thought maybe someone would have a build close to this that had a good map. I will consider using the SE TB, but I am looking for a lot of torque down low, so the smaller TB might just be the ticket.

Do some checking around. A 117" with head work like you did I'm thinking most will tell you to do a 58mm SE and a high flow air cleaner. Just my .02 but you have a lot invested don't leave anything lay on the table at this point. Your down low TQ is going to be decided much more by your cam choice then the TB.
