Thread: Lynch's 6spd / VE-T thread

o really? Got anymore info to back up this claim

just because it's there don't mean you HAVE to use it.

i

not a claim, plenty of info and facts around. intercooler and lots of intecooler pipes drops pressure. buy the time it gets to the intake manifold, the 8psi spring will read 7 or less. running it from near intake manifold will account for pressure drop and keep the wastegate closed longer thus you have more boost. Also running wastegate on vacuum is no good should be before throttle body

Yup, intercooler and piping pressure drop. I've seen it personally, but if you search you will find plenty of members having the same issue.

yes thats not what im talking about. I'm talking about the nipple on the turbo connecting to the wastegate I dont see how that will drop 2psi

I understand the concept of keeping your intercooler piping as short as possible

boost pressure at the compressor housing will be more than what's in the intake manifold area. (looking for the thread for you, i can't think and type without confusing everyone.)

even if the intercooler pipe is really short, most intercooler will still drop the pressure about 1 psi.

its okay keo i will do my own research

Looks good man. Can't wait for a ride.

Is it done done? Did you drive it home?

Its very much true, if you have a 1psi pressure drop from the turbo to the manifold then its common sense to say if you use the nipple on the compressor that you will open the wastegate 1psi sooner than if you had it on the manifold.

Pretty simple stuff.

Most intercoolers have about a .3 psi pressure drop so at the most with piping and everything your safe to say about 1 psi at the most difference.

Thing is, it might depend on the intercooler too. If you are using a high quality one ($300+ easily) then you may not see any issues. Most of us are running $100 eBay ones....
