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
basic math says the injectors will support 986whp in your case, though youll probably run out of lpfp before then (not that 100% duty cycle is good, or anything, but...)
"floaty" is a product of no belts in the tread center and a soft sidewall, it isnt something you can align out.
They drive far better at 16-18psi then they do at 30.
Meth tank and injector would skip the E and negate the need for bigger injectors and easily put you past 600, but it would be a constant maintenance/fill thing.
The stock heads dont flow well enough to benefit much from cams at rpm limits a stock engine will live at, + the extraordinary expense...
