yeah, i drove my car sounding like open headers for 5 mos. and just thought it was normal b/c i didn't have a dump tube it's like a whole new car now, sounds stock, turbo actually spools up, don't smell like exhaust when i get out of the car, etc., etc. the day the wg came in, i was in such a hurry going to big race, i took it out, bolted it up and drove.............

man, wtf? i had the boost controller hooked up originally to the top port and the side port straight to a vacuum source, i had it like this for a few days and the bc was working fine, was fully adjustable, no spikes, everything was perfect, turbo spooled quick as hell. i thought you were only suppose to hook up electronic bc's like that, but it worked fine, so i left it. then i'm reading around and hear that that is very dangerous and bad, so i swith it to the top port just venting, and the bc in line with the side port and now i have some serious lag. what is the danger of having it hooked up how i did with the top port to bc and side port to vacuum if it works fine?

i got my boost controler hooked up like it says in the instructions. between the turbo compressor housing and the wastegate actuator, does this cause more lag then connecting it between the intake manifold and wastegate actuator?

HMT-Admin

it actually spools faster when you hook it up to intake manifold rather than the compressor housing.

you're actually losing boost that way, the wastegate sees x amount of boost from the compressor, but by the time it goes through your intercooler, piping, etc, you've lost 1 or 2 psi, where as if you have it directly to your im, that is the actual boost that is going to your engine, so you're actually boostin a couple less pounds than you think.

dam no wonder i spool up 10psi at 6k rpm w/.60 trim t3 in 2nd gear. ***! ima do that ---- right tommorow. but isn't what my boost gauge reads the actual psi i'm running? it's hooked upto the intake manifold. i'd hate to have to retune this crap again.

projekteg

yeah, as long as your boost gauge says that's what you're running, then i guess you are. but like if you have an 8 psi spring in your wg, and hook it up at the comp. and you're only running 6 or 7 psi, it's b/c of the pressure lost betweent comp. and intake. it doesn't really matter if you have a boost controller cause you can just raise it anyways, but if your boost gauge is in the im, then whatever is reads is correct.

Both the BOV and the wg are connected inline with the fuel pressure regulator. the car builds 10psi in first gear before 5500k rpm and in 2nd gear 10psi by 4800 rpm. Vtec is set at 4500 rpm. it builds up boost way faster connected this way. i also pluged the nipple on the compressor with a rubber boot. Is the BOV a better place to connect it to then inline with the Boost gauge which is connected under the intake manual inline with the cruise control?

projekteg

i have my boost gauge t'd in the same place you do, and i have my bov t'd in to my fpr, and then my wg t'd in to my bov. which sounds like teh same way you have it, mine spools up pretty fast this way also.

cool dude, thanks for all you guys help.
