There is a point on the RBC where going to a bigger TB doesn't help...the casting just doesn't allow it. I ported one recently and I don't do a lot of motors without ITBs so I can't remember the size but I think it was a hybrid racing 70 or 74. All I know is the casting wouldn't allow for the TB size and I had to taper into it to make it work.

I say run a simple setup with RBC and spray the **** out of it

What I-beam rod do you have? You will need a pretty strong rod to handle a big hit of nitrous all at once, so you may need to ramp the spray in with a progressive controller or hit it with 2 stages.

 

You confused me a little on the intake manifold talk lol. I should run h beams because of the large shot huh? This is all in consideration at this point. Put my plans up on here so you guys can nitpick and let me know what adjustments should be made before I go empty in the bank.

 

biggest you can go on an rbc is 70mm before you run into the iacv passage. you can weld it up and go bigger but that's just more work. the rrc doesnt have this problem because it doesnt have an iacv port.

how much power are you trying to make?

 

Ok then I'll stick with my original RRC plan with that being said. Although I wasn't planning on making the tb any bigger than 70mm. I don't really have a set power goal in mind but I would like be around 42x on a 175 shot so maybe around 24x on the motor no juice. I've read the RRC outperforms the RBC so the difference in price speaks there.

 

What brand is the rod?
