How much HP would I gain?

[shawn941]

How much would I gain from switching from FMF gold series fattys to T5"s?

 

I have a welded crank, +4 timing, cool head 18cc domes, and a 2-1 carb.

 

Thanks for any help. I am mostly looking for mid to high power.

if you want mid-top you should loose the 2into1 carb set up. most ppl that run 1 carb set ups are looking for more bottom end power,,,,,

Ive never seen a good running 2 into 1 carb setup. Ive had a few friends with them and they all went back to dual. IMO its a gimmick. Kinda like boost bottles.

 

 

 

As far as your pipe choice. Id say stick with what youve got. If anything the change will just shift your powerband a little bit higher. If you arent ported Id spend the money on that.
