Have done a search but could not find any dyno testing of going from a stock intake manifold and going to a ported one with or without a 65mm t/b for that matter.
Buschur somewhere said he did this way back and it was worth 15whp but could not find a dyno sheet..

Would also like to see the benefits of going from a stock exhaust manifold to a ported one?

Does anyone have any links to dyno testing of the above

Cheers

 

is everyone just buying blind with no evidence of power gains?

 

bump?

 

Yes this has been covered ad naseum....For some reason the search function just does not work well on this site (should use Google Enterprise Search )....

Try searching for threads started by davidbuschur and then type your key word..
