What is the max boost that is recommended to run on the stock twins with all supporting mods? How much power can I get upto with them?

 

this question has been asked many times. Search. 15 would be pushing it and the most power would maybe be around 340 to 350 whp on a stock motor.

 

You've been on the forum for 5 years and aren't familiar with the search function?

Yea i searched but for some reason didnt find anything... sorry

 

Ive heard 14psi is the most you cant push on stock twins...

 

The stock twins will boost up to 18 psi or so and make up to 380 HP. They obviously won't last very long maintaining that level of boost for any length of time. I have run mine up to 15 psi at the drag strip and they seemed to hold up well. It really depends on how reliable you want them to be. Anything above the designed pressure (10 psi) will shorten the life. For street driving I wouldn't recommend going any higher than 13-14 psi.
