What fuel are you planning to run again???
Yeah but this thing can do more than just slow down the boost response you can limit how much boost is run in each gear which is what I plan on doing. Like I can limit it to like 20psi in first, 30 in second and let her rip for 3rd and 4th. This is extra useful for when I drive the car on the street. At this point in my build it is not that much money considering how much I have invested in the car and this is one of those cases where the best part for MY BUILD is the most expensive. Reliability and track proven results back this up.
Are you going FWD or something . Your car is awd, if your on the the right tire there will be no need to limit boost. You gotta think of load also. My car only hits maybe 20psi in first gear, and feels like a dud, I hit 2nd it goes to 26psi and feels like I hit it with a 200 shot. There isnt enough load on first gear to really get more unless you got some spray to spool it up alittle more. Im running a single tial 38mm on my divided setup, and I can turn the boost down to 16psi with a 14psi spring inside. I doubt you will have any trouble with 2 gates
Again you dont want to slow down boost response anymore then its already going to be, that would only be good if you were fwd. Spending 850 on a boost controller, when your getting aem and when you can run there controller in the aem program, or anything else is a waste of money, but yes its your money. Like I said most high dollar racing teams with dsms dont run nothing more then a hallman or the aem boost control. 850 could be stage 5 rear axles, or the 300m big output shaft transfer case to go along with that nice driveshaft you got, which you will benefit more from.
Shawn from Boost Boyz is FWD...
Good luck with it. I think it's going to be a headache trying to control the ebay gates with that controller. I would have run tial gates with a hallman instead.I run a hallman and a single tial on my twin scroll and she has no problem running 33psi. My car is knocking on nines and it should have been but the top end of the track my car wasn't feeling it.
I'm more worried about one of the gate NOT opening which has been an issue with ebay wastegates.
The simpler setups work best. Less of a headache, easier to work with. Then when there is a problem and there will be problems, there is less stuff to digg thru and figure out what the hell is causing the issue your having.
EDIT: I see your going to make the right choice and get a hallman. Good man!!!
Amen to that.
Keep it simple electronically. Get the car running right, get the drivetrain/motor ready for war, turn the boost up and get ready to learn how to drive a manual car again. Its a whole different animal, because when you are making that kind of power, and dont wanna completly break the car is a constant battle of finding the medium.
Worrying about .2 of a second off your time is something 7 second guys worry about. You can turn it up a pound of boost and gain that.
AWD's battle is holding the car together, and getting it down the track. All that other crap it for the birds.
Dont turn this into "project 9's more complicated"
This is a true divided setup so neither gate will see a true 50psi. I really only think it will take 45psi but for argument sake just use 50psi. Each wastegate is only regulating half the exhaust flow so 25psi max each. I think that a ebay wastegate, which by the way cost less than 100 , can handle that much boost.
Shep may have messed around with Boost by gear but isnt using it. That pic is a pic of the 7.7 setup along with his mod list. He uses a Hallman. END OF STORY.
As far as the ebay gates. I'll say it again. When they stick they stick CLOSED!!! That will put shaft speeds on the turbo thru the roof and boost way higher then you want. If the manifold is setup up wrong then it's time to sell it for something else.
All the bigger wasteggates are going to do is allow you to run a much lower boost if you want. The larger surface area will give you steadier boost control.
This is not a step I would be ignoring as this will break that pretty motor.
And IF the wastegates fail, what are the chances that they will both fail at the same time? DSM-onster loves these things, lots of people have had good success with them, I've actually never heard of anyone having problems with them. Now it's time to let them get pushed further than ever on Slippi's car and see if they still hold up.
I don't think 1600cc injectors will support 40+psi on e85?

Psi isn't the factor it's power level. The new Fic blue max injectors flow more than old school 1600cc injectors too. They make 1850cc to just for shits and giggles
