Advice on injector size and brand from experience?

[Pat D]

As per title, is there a prefered choice in injector brand and rating for 600-700HP from experience?

I will be using an Autronic SM4 ecu.

Ev14..

Ev14..

cc rating?

[prj]

750cc or bigger, assuming 4 bar fuel pressure.

I agree then I would as I have this setup

A good fuel system will also be required!

I plan on using the standard pump feeding into the 034 1 litre surge tank in the engine bay, which has a 044 inside of that.

Five o have 1000cc EV14's. Are there any issues with going too big with injectors?

[prj]

1000cc EV14's will be fine.
2000cc's will be a bit worse than 1000 on low pulsewidths, but still manageable.

Bigger than that I would not recommend.

Had a look at that one litre surge tank. Good idea but saying it will handle 700 at 6.2bar means I can't see it as a viable option for my turbo upgrade. Think I'll stick with a hefty intank one instead.

Other options on injectors are the ASNU ones custom made to spec using bosch plug bodies and ev14 internals to any desired cc.

Five O sent me an email reply recommending this injector http://www.ebay.com/itm/ws/eBayISAPI...e=STRK:MESE:IT

Sounds kinda good?

A lot of bold claims, but zero data.

Latency is not a very big issue, linearity is. Them claiming they are more linear than EV14 - well, let's just say I would like to see some graphs.

Just go with EV14's.
I don't even see why you would get 1400cc injectors, unless you are running E85?
On gasoline, 750cc is above the limit that the stock lines and a single 044 will handle. Any bigger is pointless without serious mods to the fuel delivery system...

[Pat D]

Big claims is what I was thinking as well, not much there and no reviews.

I'm thinking of leaving the stock fuel line feeding into a surge tank in the engine bay with an aeromotive A1000 to the rail, should be able to support a decent amount of fuel?

[Pat D]

Will be on gasoline, but thinking of having a map for E85 as well

[prj]

It's not that simple as "having a map for E85"...

E85 is a good fuel, but it's energy density is more than 30% lower, so your fuel delivery system would need to be able to handle up to 1000hp on gasoline, and that is not easy or cheap at all.
A single pump with stock lines will not do for sure.
