Mass air and throttle body and injectors

[juic3d]

Just curious what Is the right size for a heads cam intake. It has a 306 f cam performer heads and rpm 2 intake. What would be the right size injectors and mass air, throttle body

IMO, 75mm mass air and TB is perfect and you will still have room to grow and personally, I would do 30lb injectors so you'll already have them if you force induce. I'm sure 24's will do the trick and I'm sure there will be a few people say the 19's will do the job also.

Yea I have a cnl mass air calibrated with 30 pound Injectors but a 65mm throttle body. That's probably killing me

I wouldn't say its killing you but its not helping imo. If you're gonna stay N/A I wouldn't worry about it much. These are just my opinions. If I were starting fresh with a stock car, I would do it this way to begin with. 75mm TB, 75mm mass air, and 30's. I'm sure a lot of us here would agree.

He may be spraying it, too.

Im running 19s with a 75 Bullet & 70mmTB on a Heads Cam Coupe

76mm maf. 70mm TB. with 24lbs if staying N/A because technically 24# injectors can provide 370-380hp at 100% duty cycle. If you are boosting or spraying it prepare to buy 30#+ injectors because that is what it will need.

x2 on bigger injectors for spray or Boost. My old Heads Cam car had a 100shot with 24lb injectors. Car ran 8.0s on motor & 7.50 on spray & would have gone faster. But ran out of fuel up top on spray

id actually say skip the 30# and go straight to 42#

idk why you didnt put a better flowing injector in there from the start man. HCI cars with boost or spray and the fuel to support it are 6's easy (given traction etc....).
