suggestions on Forged and Forced Performance heavy duty wastegate actuators
ok, I'm done with straight pump gas and have a meth kit on the way and want to see what the evogreen can do.
that being said, I'm wonder if there are significant improvements to be had with the forge or forced performance wga over the evogreen stocker.
I'd like to hear some people that have before and after boost results and I'd also like to hear from people that have tried both brands.
on the other hand I'm going to setup the aquamist hs-5 to dump boost to wg levels in the event of a meth failure by utilizing a mac valve. I wonder if upgrading the WGA to achieve a higher minimum boost would be a bad idea given the fact that I could go terribly lean if the meth kit fails.
let's get some discussion going.
p.s. I might just skip this altogether and do a 35R kit with external WG...been wanting to do that for a long time.

I would get the FP actuator as I have seen personally on a friends evo who had it on his 9 turbo, hold boost longer and have less drop off to redline. And had another friend who had the forge, say it was crap. Personally I would buy FP over forge any day.

I've heard people say the Forge is better. I don't have any experience with either WGA. Have you tried the WGA mod yet?

The FP one is a lot cheaper I believe too. The forge is $200 and FP is around $100.

well I have tried both,and the forged is better,the boost was not held that good with fp,or it could have been my driving,but with the last setup with the forge there is noticeable difference.
I think your concern with defeating the failsafe is valid. I tried the FP wastegate on my car, it hit 23 psi in the midrange just on the wastegate (ported exhaust and WR turbo). Others have found the same thing. That wouldn't provide much of a failsafe.

another thing I've noticed from tuning many cars with upgraded WGA is that some cause the load to be lazy and not peak until well after a stock WGA. For example here's an old log from my car with a stock WGA vs some customer cars with upgraded WGA...these are just some examples, I thought I had some data on more cars with lazy peak loads but this is all I could find with a quick search, they may have another problem but It's stuck in my mind that customers with upgraged WGA often have lazy loads.
My evogreen stock WGA - 26psi spike - peak 280kpa @ 3800 - stock plastic BOV - EVO8
Customer evogreen spike to 23psi Forge WGA - peak 269kpa @ 5600 - Forge Race-Adjustable DV - EVO9
Another customer, this time with the White Rabbit turbo - FP WGA - 24psi spike - Forge Race Adjustable DV - EVO8 - 270kpa peak @ 3600
EVOgreen with FP HD WGA - 23psi - EVO9 - Forge RS DV - peak 293kpa @ 4000 - Forge MBC - seems a little late given the fact that it was kicked down at 2000 RPM (sooner than everyone else)

ive heard alot of good things about the fp actuator. i cant say the same for the forged actuator. the fp is suppose to hold boost alot longer and w/o hardly any drop off to redline.

I didn't realize that the lazy peak was the casue of the FP actuator until you posted about it. I figured it was just my mods causing it, but now I'm 100% switching to the Forge.

yeah it's a pattern I've been noticing lately, kind of puzzling. I haven't got my head wrapped around why it would be delayed though. I'm not convinced one is better than the other yet.
Mellon, how could more pressure on the wg, (by use of the FP higher pressure unit) cause the peak torque to occur later in the rpm range. I'm assuming that's what is being said. The only thing I could think of is that the 'initial' spring pressure is slightly less than the stock or Forge unit. This would be similar to less preload pressure. Then as the boost rises, the spring pressure catches and surpasses the other units, as far as pressure on the wg is concerned. Is this what your thinking, or do I have my understanding confused? It wouldn't be the first time, or probably the last.
