What size injectors are guys running on E85 with an FP red on a stock motor? I have 1000cc now and they are getting close to maxed out on 93 octane and I'd like to add an E85 map. I have a set of FIC 1350s laying around but I wanted to see what others were using since this seems to be a common turbo to run.

Also on another note, can I push the stock engine harder by upgrading the rod bolts since it's cheap and easy to do or is that not worth it?

 

I went with FIC 1650 hi-z's for mine. Plenty of fuel for the stock block, and will still be enough when I build the motor and put it on kill...

 

I have PTE 1200s and a double pumper running at 80% injector duty cycle on e85.

I am at 95% duty cycle my pte 1200's on e85 with a double pumper. Switching to fic 1450's shortly.

 

I would say the FIC 1650 and when your ready you for more power you will have the fuel!

 

Yea I would do that but I already have the 1350s laying around that's why I'm wondering if they are good enough. Also, is a double pumper really needed or can you run a walbro 450 and be ok?

Also, how much more hp/tq can the engine take with the rod bolt upgrade?

 

Rod bolt upgrade still limits you to 400ftlbs. It's the beam of the rod that breaks, not the bolts, typically.

The 1350's may do it. And on the stock block, a single walbro 450 will be plenty..

 

1350 will be fine the things with the 450 pump is that you may need a fpr

 

If you drill the siphon to 9/64, and do the rewire so that the stock low voltage capability is retained, an afpr isn't needed. mrfred has a pretty lengthy thread on it in the "how to" section..

 

I'm over 90% on my 1250s, I need to get some 1650s later this summer.
