Injectors
Hey guys, I've been trying to do a bit of research but haven't found much on the topic. Is everyone swapping Injectors once they reach a certain HP? I'm running e85 and haven't been able to even find what HP the z06 stock Injectors max at.

Nope. And the stock injectors are not large enough to support any mods with e85... and the fuel system does max out pretty early as the power comes up.
I'm not in that crowd, but my understanding is most people are running a port-injection style of meth for additional fueling under load. I don't know how reliable or how carefully metered that is.
Others have tried different pump lobes and so on to generate more fuel from the stock pump/injectors, including different lobe styles and shapes as well (with more strokes per rotation even).
I have not seen a solution that made me want to step up with my handful of cash yet...

I think someone did (Lingenfelter perhaps?) but if I recall the increase was modest, like 15% more flow or something like that. Not enough for me to remember thinking "Well, the injector problems are solved". And they weren't cheap!

Yea, I think I had found two after market injectors that apparently work well, but not enough of an increase. And wouldn't be so bad if there weren't 8 of them you had to swap out.

HOPEFULLY the ZR1 parts are a true upgrade and are directly replacements...
Katech: 12-15%
Lingenfelter: 30%
FIC: 30%
At half the flow the Katech units are half the price of the FIC/LPE..
I think it was Cunningham Motorsports or CPR was pushing the new FORE triple pump, add that with FIC injectors, and a Cam you could finally push enough E85 to not rely soley on meth. But you're also talking $10+K in fuel mods alone, I'll keep the meth until more options are avaliable. Road trips wont be an issue if you stay out of the boost. Plan ahead and find a speed shop if you're addicted to it

I'm not too familiar with meth since I've never used it, but how does it decrease the amount of fuel needed for injection?

If you don't mind mixing e85 with 91-93 then you can easily run E30-E40 with mild mods up to about 700rwhp and still gain all the benefits of E85. If you don't want the hassle of mixing E85 with premium gas then you will need meth to use 100% E85 to compensate fuel requirements unless you do a low side fuel upgrade or cam and injectors. Meth is just a progressively controlled injection of methanol to aid in fueling when under boost. There are tons of articles online and around here on it. A meth kit is about $600 but labor to install will be high unless you do it yourself and then a tune for it. Cam and injectors would be MUCH more expensive but if you don't get crazy with mods you can just mix E85 with premium for a low blend and still be fine. Read read read, there is tons of info out there, I'm not an expert by any means but I read everything I can get my hands on and listen to the guys I notice that are very knowledgeable on the subject.

there isn't enough high side pump to support much over 800 rwhp on e85 unless you have so many meth nozzles it looks like a purple C7...
