Hello everyoneI have a 18 cvo with a zippers 468 bassani power duals and 2.0 fullsac cores would be worth it to change to change to 64mm throttle body and bigger injectors.

 

Sorry about that I have to learn how to type. Would it be worth it to put on 64mm throttle body and bigger fuel injectors.

 

 

Yes I had it dynoed. Where can I send it to get ported?

 

You really only need to increase the throttle body size if you go big-bore. The injectors couldn't hurt, but I agree with $tonecold's recommendation. Dial in the tune.

 

 

What is the stock throttle body size on the 117 cvo

 

All of the factory M8 throttle bodies are the same, doesn't matter if its a 107, 114 or 117 (55mm). The SE replacement throttle body is 64 mm and comes with a new intake manifold. There is also a SE replacement intake manifold for the stock plastic one that you use your stock TB over again. I am not so sure porting a aftermarket (SE) manifold is worth it. We have tested a couple of them and not found any real change in performance with them over the none ported versions. These were the 64 mm units that we were testing on 117 and 120 engines.

 

If it's running well don't screw with it, going with a 64 & injectors means it will need a new tune= $1k spent for a couple of HP, the 468 is a TQ cam anyway just use the TQ.

 

I think I'll just go with se manifold to replace the plastic one
