Does your logger read IDC %? If so, this will tell you when it'll be time to upgrade. It's not recommended to run anything higher than 85%, although it is possible.

Watch your idc to find out.

ok so nothing more than 85%?
ill have to take a look and find out.

as you can tell i bought my car modded so im trying to see if i need to change anything. i know i want to upgrade my turbo because ive heard im pushing it with 28lbs on it. anyone have any opinions on that one?

After a quick glance through your mods, I see you could use an AFPR to control the 255lph pump.

Other than that, I would again look to your logger. Again, not sure what datalogger you have or what/how it reads, but if it reads airflow, you could compare that to others as well as a compressor map for your turbo to see if you're flowing enough air. Or just look at who else has the same turbo and how many psi they're pushing.

It would be fair to say your probly @ 100% IDC on those injectors,my buddy is on Fp Green w/ 650 and 80/20 mix on E85 and he's at @ 100% @ 28lbs. If your not you have to be pretty close to it.


But if it was me i would definitely upgrade inj.

ok thanks for the advice ill have to look and see.
now price wise?
now what would you pay for this car to see if i got a deal? or low balled. i dont think i got low balled at all

ye looking through the dyno sheets i see im prob one of the highest hp ratings on 650cc injectors.. but turbo wise id say im safe for longer.. to be safe should i just go to something big like 1000cc injectors so the IDC would be lower. isnt there a chart somewhere where you input your numbers and they tell you what you should be running? like on RC's website..

ye i just ran the numbers on RC's website calculator and 1000cc injectors seem ideal. with my horsepower and flow they recommend 937cc/min injectors.
now will this require a re tune?

Does it really matter? You have it whether you got a great deal or a horrible deal.

It probably won't require a full retune, but probably at least some adjustments.

true man very true.
BUT i got into some shit and might have to sell already.. thats why im asking
and trying to inquire about what people might find "wrong" with my set up.
ye no what i mean?
