In my case my clutch will let go before I get to the point of maxing out the injectors. So it's all good!

Any downside to maxing 460cc injectors to hit 250rwhp? It wouldn't be a normal occurrance, just asking the 460s to stuff enough 100 octane in to cope with 15psi for a day here and here

you;ll be fine, you should just be hitting 85% DC at 250rwhp or so....but you have no room to work with... me, I'm not looking for no more than 220-230rwhp, so I have a bit of wiggle room.

450s seem to be at 90% DC at redline at 12psi for me... too small for 250whp on a track car, IMO. for a street car that only sees it every once in a while, it would probably work.

You guys really think Hustler will have the stones to turn up the boost?

I happen to know a guy who knows a guy who's 1.6 greddy with RC Eng 440s and a Link made 260 hp at the tires on a dynojet.

for the price difference, the 550cc headroom is worth it. I'm thinking I'll run the car at like 10psi, and see what kinda power it makes on MS with 3" exhaust and no cat.

no, I won't. Too much mechanical empathy. We'll see. I only wanted 250whp in my vw when I bought the turbo system. I ended up with 442whp, but it never saw the track. I'm really afraid of breaking stuff, and blowing up the motor even if its tuned safely. My vw really gave me hell.

At 220rwhp, equal prices, what benefits do 460cc injectors bring over 550cc injectors?
