the water pump is electric my dude. there is nothing to underdrive but the alternator/ac and it clutches itself off anyway. waste of money unless you need the damper for some reason (rpm/built engine)
It's a seamline. They aren't solid, think of it as a gigantic rollpin. Don't bother replacing them, the new ones will be the exact same. It's part of the design.
the pfs pump is drop in and plug and play. it's good for ~850 wheelhp on e70 or a little less on e85. Beyond that you'll need more pump or a second pump,
no complaints with mine (PFS). plug and play. they're good to 850ish on ethanol. if you have higher goals then that youll need more pump.
also, do the bigger fuel line while you're at it.
no, you arent running low 5s with 7xx hp lol.
trans wont hold in 6th, so we pull about 8 pounds of boost in 6. putting in a pure stg 2 shortly.
if i were to do it all again i'd have put a pure 900 on the car, but it runs fine for what it is
You're going to need a top mount/950+hp to keep up...
My P800 made 753whp at ces on e70 on a 100 degree day and it wasn't maxed out on full e85 because we left some in it for the trans' sake. Upper 700s is easy enough with a good intake manifold and free flowing exhaust. A manual car can hit low 800s
