Turbocharger intercooler piping size

[Pollushon]

You need to stop talking to whoever it is that's telling you this stuff. Ecos love boost. I rammed 14 pounds into mine for years

Super 6 36lbs would suit.

Just step it up to 3in at the turbo and use the same size all the way to the throttle.36lb will go to 8psi or so 42 to about 12psi j7st but big injectors off the bat or you end up rebuying over and over .

Yeah your probaly right it was just because its stock at the moment and didnt wanna put too much power but if you think it wont kill it that would be sick, and cheers i think i might use 3” but from the video that was send it suggested around 2,25” to 2.5” Id say if i went 3 “ itll have a small amount of lag

Run as big a pipe as u can. All my pipe on the vortech bmw 540i runs 3” for about 600bhp. Prob min 2.5” but the larger pipe u run the less static pressure (air resistance) u have so effectively the less boost u lose due to the high pressure plumbing.

Ok ill probaly use the 3” then recon itll fit should it be the hole piping or 2.5” to the intercooler then 3” ?

The engine runs 3" inlet pipe standard no point going smaller.turbo hits hard as hell and just breaks the tyres loose on 3 inch anyway lol

Ok lol so ill do full3” piping and for fuel injectors i was thinking of just the 36lb injectors because the waste gate opens at 7.5psi, and when i go bigger later ill just rebuy them... ill get over the money

36 lb/hr only gives about 310bhp on 6cyl @ 3bar fuel pressure. I’d probably go slighly bigger and use an adjustable FPR and if u have too much fuel trim the fuel pressure down. That way if u wack up the boost u have some margin for error. Depends how u are adjusting fuel but the injectors these days can function well at low duty cycles.

You doing buick or ecotec .they really wake up above 10psi here' an old vid
