2.75 or 2.25 for my 300whp goal
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

Re: 2.75 or 2.25 for my 300whp goal
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
