This came off my DA and I was going to put it on my DC. I am going to me making in the upwards of 600 to the wheels. Do you think this dp will flow enouf for that hp level. The metal is mild all manderal bent. What about the waste gate dump tube you think thats ok?

thanks

 

what size is the piping?3" will be fine,4" would be better.

maybe with open dumptube

oh,i didn't even notice that.definitely want to dump the wastgate by itself.

I have done over 600 with the dump tube running back into the down, I usually run it into the short radius of the bend. You can't hear what's happening when the wasteg gate opens to the air.

i'm not saying you can't do it,but it would be more beneficial,esepcially if that downpipe is 2.5".

i'd like to see 600 on 1 tial 38

 

I don't think a 2.5" down pipe will make 600 either.

What does the size of the wastegate have to do with high HP, It works hard only on low boost.

 

Its 3", I was thinking that there might be to many bends. There is 4 90s. I cant stand hearing that wg open. If the difference is small its worth it having it quiet. Plus you dont get all the black carbon everywhere.

 

Recirc is just fine. but you need a bigger wastegate. or 2 38mm

 

The idea of a wastegate is to keep the boost in check at low boost. At 600 whp the gate is doing very little as it isn't bleeding off much pressure .

My single 38m Tail gate holds boost from 11 psi all the way to 34psi.

 

I was thinking the same thing, I am going to be running max boost out of my T4 62-1 untill I get a bigger turbo. Then I was thinking about adding another 38. But is that going to be too much?

Exactley, I've made just under 600 whp with a single 38mm with a 1 bar spring, held 28psi rock hard.

 

It seems alot of people don't really know what the wastegates job is .

 

lot of people do dual wastegates cause they want to run 7psi on a GT40 for some reason... I had a 38mm and ran 25psi on a 35r with no problem, never boost creep or anything.
