Re: anybody experienced with twin wastegate setups?

on a 4-1 if one gate is not enough, I would add the second set like 1-2psi higher. I think that might make them work alright, since the one would need to be completely open with boost still building before the other would begin to open.

twin gates are only necessary if you can't get boost levels low enough.

Re: anybody experienced with twin wastegate setups?

when you cant get them low enough that means your manifold design is a pile of ----.

you should never need more than one wg bigger than 44mm tial.

unless your running a split collector and then id use 2 38s

if you fucksticks look noce and close youll notice that that manifold does in fact have a split collector so the 2 wgs are necesary.

god most of you ******* are so stupid.

Re: anybody experienced with twin wastegate setups?

Hey Guys! Thanks for the comments !!!

THat's nothing new, twin scroll turbines have been around forever but if i understand well, to properly use a twin scroll turbine, you should separate the runners of each cycle of the engine to minize the backdraft that travels back to the non-firing runners at each engine cycle. These backdraft movements are certainly responsible for LAG but in which proportion, I have no idea and I can't wait to find out.

ok I decided to give it a shot myself and make my own twin wastegate manifold right now to mount a gt3582R on an all forged H22! I thought that it didn't have to look like something I, or anybody, ever saw.

I am not 100% done, still have the ceramic coating to go, but here's where i am at!

Anyone talking ---- about AMS is retarded. Being that they hold the record for the fastest street car in the world and the highest HP Evo's in the world says engough. They have a fleet of nine second evos.
