Hello, I currently have the marine 8.1L 42# injectors. Im seeing 63% at 6900 rpm. When I install the procharger Im only going to spin it to about 6500. Where the IDC is about 55. Will I be good if I only run about 8#?

 

I think you will get by, but your idc will be over the suggested for sure.

 

Thanks, If I have to I will set the shift points a little low until I can get some bigger ones. Eventually would like to have about 12# at 6500.

 

You will need larger injectors.

 

would 60s be enough? Or should I plan for 80s? May run a e85 mix when I get to ND. And which ones will be P&P for my 01?

 

Probably need the multec adapters to run the injector you want. Not sure how much aftermarket multec has, haven't really looked. 60s will be enough fuel for your engine...I don't think that older LQ4 will take more than the 60s can deliver. I ran 50/50 mix with e85 using the 60s and they had just pushed over 90% duty cycle at 20psi and 6200rpm. So they can move quite a bit of fuel.

 

ok, You wouldnt happen to have any links for those 60s do you.

 

would these drop in without needing spacers?

Found a set of 80# injectors for my truck for 300. Only 1500 miles. Would they be too much for 550whp? Eventually I'll be aiming for 700+ once I get a 80e installed.

 

Which 80s are they?
