Yes it will get close to 500HP but it is really hot and turbo life is not the best. A turbo upgrade is a very smart idea around 350HP. I will bet that there will be a lot of vertical scratches in the rear cylinders from ring scuff without a turbo increase. If you start out with a 215 pump don't mess with the DVs. You already have 181's which are pretty good. Most larger DVs run hot and smoke because the fuel timing gets messed up. You want your fuel injected quick and early. This gives more power than late entry fuel along with cooler EGTs. If you want way more fuel than the turbo can use it takes about $200. Buy a good 4k GSK with valve springs and grind the fuel plate to a 100 profile. You will never ever clear it up with a stock turbo. I ran this setup on 362/475 twin setup and still had plenty of fuel. For injectors spend the money. You want quality parts here. Period! Always buy injectors bigger than you need and use the AFC and fuel plate to limit fueling. Power is easy to build and you will want more in short order!
