i won aluminum charge piping on ebay except i wasn't paying attention and didn't realize its 2.75 and not 2.5, so i was gonna say do you think 2.75 is too big ? he doesn't have 2.5 but does have 2.25 which he can offer me. my power goals are 300whp @ 14-16psi do you think 2.25 or 2.75 would be best? my turbo is a 60 trim garrett w/ a 2" outlet and my fmic is 2.5 endtanks. this is on a fully built and balance dohc zc. also im not going with the traditional charge pipe routing im using a backdoor setup if will play any role in deciding. i just need a little advice on deciding which size pipe to use

 

2.75 is good

 

i was wondering if it would cause a delay in spool/boost due to the size but i definetly wanted to go with 2.75 as long as it'll be ok. now i'll just have to run a bored out gsr throttle body so it doesn't bottleneck into my 2.25" tB on my stock zc intake

 

If there is any delay, it will be minimal. Go with the flo!!!!

 

bigger is better
