as above realy thanks in advance

 

No from what i understand they are a LONG way off. ST170 heads flow to 400bhp with standard valves just need the VVT remeoved and exhaust ports opened up a little. well thats what Ian Howell told me last week

 

are the stud patterns the same tho?

 

i dont think they are, but i might be wrong as ive had a few beers

 

same stud pattern, alot bigger port shape

 

WHY would you remove VVT


its one of the BEST engine advances about,,,, different cam timing to keep valves open longer and allow MORE airflow and then lower the ca timing for better lag free driving round town meaning no need to change to 2nd to get round town

why would anyone remove it,,,,, unless they dont understand how to use it

but like taking a 16v engine out and fitting a 8v engine,,,, why go backwards

whats the cam duration and lift like at high rpm,, considering the vvt reduced the lift and duration lower rpm,,, thus lowering the air flow on a good flowing head

 

for his next trick he will remove electricity from hes house and fit candle

remove central heating and fit a wood burning fire in each room
