Forward Motion Wastegate Drive Test - SRT Forums

wazzuman · 12-01-2007, 10:00 PM

I just installed my forward motion wastegate actuator and took my car for a test drive tonight and MAN WHAT A DIFFERENCE IT MAKES!! The only thing that seems too good to be true is that my car is spiking at 20 to 22 in third and holding anywhere from 18 to 20. Isn't that a bit too high for a '04 with a stock fuel system at stage 0? I didn't throw any codes that I can think of. How would I know if it did? It didn't backfire either so it doesn't seem to be running too lean. Maybe I should adjust the boost lower. I would like to keep it where it is but I don't want to blow up the motor either since it's my daily driver. What do you guys think?

lower it your running out of fuel the only way to truely know if your safe is with a wideband. I would spike 18psi.

Yeah I figured that was insane but it was one hell of a rush for the few times I did stomp on it. I felt like it picked up 30 to the wheels!!

How much part throttle boost do you have? Is it hard to deal with on the street?

It doesn't have any that I am aware of. It's also very streetable but the turbo spools up a lot quicker now. It is a very explosive power but only if you need it. It is hard to adjust right now with the wet pavement where I live. I need a nice dry day to actually see how high I spike and where I am holding at. I turned down the wastegate now so it is spiking around 18 and holding at 15 to 16, which seems to be a good spot to keep it at. I am wondering if I should put the heat shield back on. I decided to leave it off for now because I like the added room in the engine bay.

i would put it back on and take no chances. ive heard to many stories were people melt their reservoirs.thats just imo

Yeah I probably will once I get the wastegate set to where I want it to be. It seems to keep the turbo hotter though. But I guess it saves the reservoir so it's either one thing or another.

I dont have mine on and am running 24lbs no problem with melting anything.

FM wga is definately where it's at. i've seen a lot of boost rising solutions and this one takes the cake. there is a bit of ptb, but it's not anyway near as bad as some of the other wga or ebc options. plus you can adjust it w/o taking it off. the heatshield may need to be modded to put back on though. fitment was the only downside of this wga, but it's not that bad at all. if fitment wasn't an issue i'd say it'd be perfect.

X2. Thats the same way I felt when I got rid of my stage 2 wga and got the FM. I was like damn!

That's pretty interesting. Isn't fuel cut at 18 PSI on the stock computer?

You backfire when you're running rich, not lean.

Your guage is busted.

There is no fuel cut until you reach redline. However, on stock PCM/ECU if you go over 18.25 psi the computer will pull timing back. Either way it is a loss of power.

Yes the FM WGA is probably the best wastegate actuator out there. I have had mine on since spring and love it. I had the AGP WGA before that and loved that too but wanted something that would spike over 20 psi and hold 20 psi to redline. The highest I could get the AGP to hold was 16-17 if I was lucky. Figured I would take a chance with the FM and if it didn't work I would resell it. I have never looked back since I put the FM WGA on the car. I spike 25 hold 20-22 psi. Love it.

i do believe this is with the fm turbo right?
