FAST max Injector size.

[edro]

I have a bank to bank FAST ecu (part# 30-114010) and wondering what is the maximum injector size I can use for this sytem? System is attatched to a 347 smallblock with tfs-r heads, novi 2000. Planning on puttin 20psi or more boost.

I ran 83's on the street without a problem. I havent tried 160's with a B2B system yet but Im told they are funny when it comes to idle parameters. But from what you described, 83' should fit you fine.

yea i had 83's before but I have bought 150's. Now it able to start but it stalls immediately and it's doing a lot of funny things. I guess those injectors are way too big for the bank to bank to handle.

I've heard 83's. I did get mine to start/Idle with 96's but had to choke the hell out of them on the base VE table and remove virtually all afterstart enrichment. I've since went with 83's. Bennett Racing Pro Dart 331, 325/252 flow TFS HP heads, .724 lift - 268/275@.050 solid roller, 20# F1R, FAST B2B
