Hey guys I just recently purchased a 228R texas speed cam. Im wondering if My stock injectors will be ok? or If i should go with something a little bigger?

I know guys have used stock injectors with this cam but if im not mistaken they were pretty high on the duty cycle.

anyone help me out?

If you do upgrade. Look into the Bosch 42lbs injectors through FIC. The flow 50lbs in the stock LS1 fuel rail. Priced reasonable as well.

Well I have some used ls2 34lb injectors with all the adapters, Just wondering if I need to use them or if it is just going to cause me a tuning headache.. Ive been reading some conflicting info though. I know people that have run stock injectors with a HCI setup and been fine but of coarse everyone on here tells me to go big or go home.. Id rather just sell the ones I have and get that money back if I dont need them..

Don't really need to but they aren't expensive so just get some 42's

The only way you can tell for sure is to measure the duty cycle. If you are above 80% at WOT, then you need to upgrade.

One thing I will add is that im at 4000ft elevation so obviously my A/F ratio is a little different

With stock heads & that cam your stock injectors are more than enough.

A lot of stock vehicles that I tune have more than 80% IDC. And my 434 RWHP 5.7 had ~95% IDC for years until I replaced the short block with a 418. Now I have the 36 lb/hr Bosch injectors that are just over 85% IDC.

that is really loud.. once I do intake we will have identical mods.. do you know what you are putting down right now?

[QUOTE=Jarren_b;17079043]It put down 370 on a mustang dyno with the stock clutch slipping.

Jarren_b

[QUOTE=MikeWS6;17079089]so your probably just shy of 400.. a good set of heads and you would be set

[QUOTE=Jarren_b;17079131]It drives good and it didn't lose anything down low.
For a street car I wouldn't go bigger but I'm picky when it comes to driveability.
Very strong under the curve.

[QUOTE=MikeWS6;17079152]Yeah so ive heard! I need to get my hands on an ls6 intake.. I dont know if ill ever do heads but I was hoping for 400whp..
