HeavyIron Posted November 7, 2009 Author Report Share Posted November 7, 2009 very nice!! how much? $160.00 shipped you guys would need a better form of boost control with strong wastegates like this, stock bcs can't handle it and mbc's will spool way too fast. An ebc is recommended if you are gonna run such a strong wastegate. Not running stock BCS, I am running IPD's TCV and my ecu is setup for 25psi Link to comment Share on other sites More sharing options...
GeraldJ Posted November 7, 2009 Report Share Posted November 7, 2009 $160.00 shipped Not running stock BCS, I am running IPD's TCV and my ecu is setup for 25psi Your going to find that the ecu will not like the 22psi spring. Go ahead and do yourself a favor and order some lighter springs. Link to comment Share on other sites More sharing options...
HeavyIron Posted November 7, 2009 Author Report Share Posted November 7, 2009 If the user is running over 22 pounds of boost, then I would contest that the 3-4 pound stock wastegate would be the "wrong" wastegate in their application... I think with a 22 pound spring, and target boost of 22 pounds, you need no boost controller at all, no? Since I hope to be able to push 25psi+, I am hoping the 22lb spring will eliminate the need for an external controller Just cut one off a few weeks back so sconeman could start making some universals. If you dont mind me asking what is the bottom diameter of the actuator that you got? Looks like a nice setup Bottom diameter is 2". tons smaller than the blue grapefruit that Greg has. - Although that looks awesome in its own right Link to comment Share on other sites More sharing options...

Holds 20psi solid from 4000 to 7000, starts moving the needle into boost around 3100. Link to comment Share on other sites More sharing options...
HeavyIron Posted November 8, 2009 Author Report Share Posted November 8, 2009 Thanks to my wife for capturing my best side as I was switching out actuators. This was hands down the single best modification that I have ever done for $160.00. I now make 15psi of boost at 2500rpm!!!! I have 25psi by 4000rpm. Most guys are barely into boost at that point. part throttle acceleration from 55-90 is amazing, the transmission doesn't even downshift. I have torque down low that I never knew existed. You couldn't get me to change springs. I HIGHLY recommend this setup. I just put 150 miles on the car after the switch out and utter perfection is an understatement. In two weeks I will be back on the dyno. like I said, I have a 12lb spring in my gate and push 20lb'o'boost all day. Holds 20psi solid from 4000 to 7000, starts moving the needle into boost around 3100. By 3100 I have 20psi of boost on tap :ph34r: Link to comment Share on other sites More sharing options...

In two weeks I will be back on the dyno. By 3100 I have 20psi of boost on tap and severe cylinder pressure. On a not well built bottom end it wouldnt last long. 20psi from a 19t is a little different than 20 psi on a 50trim. A 50 trim can make 300whp at 15psi... :) Link to comment Share on other sites More sharing options...

Someone once said that I would want more than the 19T, and I said no way this is more than I will ever want. Ha- they were right. If the financial Gods stay favorable, I might be throwing in a GT28 when I do the manual swap. Link to comment Share on other sites More sharing options...
Black Betty Posted November 8, 2009 Report Share Posted November 8, 2009 Be careful with that much boost at that low of rpm.... I still try to not make any boost until 2.5k or 3k rpms. I've got a spare motor but I dont want to use that just because I turned some rods into spaghetti... Link to comment Share on other sites More sharing options...

GeraldJ Posted November 8, 2009 Report Share Posted November 8, 2009 What is stronger than H-beams? pauter x beams. This is what I have sitting on the shelf just dont have time to put the block together. But even then the cylinder pressure at that low rpm, is going to cause damage somewhere no matter what.

Similiar to my 19T boost results... but i didn't go over around 22psi, I think my tune was too lean after that... ...with the 20g, boost doesn't start to build strongly until over 3K Link to comment Share on other sites More sharing options...
