Why not just go all the way to 1000s for "max headroom"?

(It's actually a serious question though. No downside, right?)

 

BR says it all the time. Put 1000's in so you won't have to change them again.

I have 680's that will be going in with a BBK turbo in less than 2 weeks on my evo 8. We will see if the 680's are doing at 26-27psi boost

 

I always thought 1000cc injectors were best suited to guys who run meth, race fuel or very big turbos.

I can totally understand the headroom logic, but if a car like the HKS CT230 uses 760cc injectors with a stroked engine and a 3076 then I don't see why a car running pump gas and a stock frame turbo would need to go bigger than that.

Ideally I want to use the smallest injectors I need, perhaps with a fuel pressure regulator (already have the defi fuel pressure gauge) - want to avoid unecessary stuff like a fuel rail etc. if I don't need it.

To each their own though

 

we run 780's in almost everything... they are the simplest to dial in, always work well... and are available...

i ran 850's when i made 499whp on pump on my dyno (injectors that are now in charlies car)....

I think i just made myself feel old.

 

There are a lot of broad generalizations, assumptions and dubious comparisons made in your post. For example, guys injecting any significant percentages of methanol can actually get away with running a much smaller, as opposed to a larger, injector than the same engine running on a pump gas tune.

 

I can certainly understand a tuner preferring to stick with what they are familiar with. FWIW, in winter weather I was in the 90% duty cycle range with a white rabbit VIII turbo (for the newbies, the WR was a billet wheel FP turbo sold in 2005) on pump gas with 660s.

 

How much boost, EVO8LTW? I don´t want to drag this anymore OT, so I won´t post again on this injector issue.....Sorry!

 

What HP and TQ can I expect with lite and BBK on e85 and tipical modded evo with 280s HKS cams intercooler, etc?

 

23 psi

 

Buy one and find out for us

 

Talk about classic caleb.

 

your sig doesn't make sense?
108mph @ 330ish whp is crap!

 

That 330ish whp was @25psi the 108 mph was @stock psi.

 

ah ha. well get it back to the strip
