Beans, do you mean the back side of the turbo. ATS is on the intake side and the turbine on the exhaust end right. up-grade that with a wicked wheel, and would perform well with a re-built stock turbo (with the trimmings stated above). prefer the bigger exit? similar to the "Gail Banks #24456?
I only ask cause that is what I am thinking about doing.

 

you may have a fueling problem, with your edge. Almost sounds like over fueling, or intake air restiction. If you return your truck to stock does it still do it?

 

Do not look at banks things to compare with anything anyone else sells. Banks sucks.

 

that does not sound right at all..how long have you run that Diablo in there?? do you get surge without it?? some early 99's do not like them off the shelf chips..thats why i went wth a custom tuner from DP..all kinds of power and no surge ever..even after i up graded to a 99.5 turbo with a whicked wheel i still do not get surge...

 

Wouldn't my EGT's be though the roof, if it was over fueling? I don't remember if it does it stock. It only does it with a load on.

 

he already asked lol sorry guy...i should of read all the thread first

 

Diablo and edge installed at same time, DP sounds like the real deal, bummer is I use my edge for gauges, so I would have invest in A-pillar gauges or something. So maybe I should do that (DP gauges before turbo stuff)

 

i would pull what you have and try stock first..if you dont get any surge..then i would put a call into DP.....i think you can still use what you got for gauges..bad thing is you are only reading what the PCM can see..

 

Yeh, I can with the edge set on stock, minus tranny temp which I want to add, so gauges might be in my future. So if it is over fueling, that is what is causing surge or is it causing somthing else?

 

i think the pcm is confused by that chip...you will know after you try stock..the early 99 turbo was always good about not surging..thats why the other guy's use the wicked wheel..the wicked wheel is a stock early 99 wheel

 

Yes the Turbine is on the exhaust side of the turbo. Our 1.0 housing is just like Banks w/o the high price tag. Also the anti-surge wheel is that same as what Banks sells only w/o the price tag.

Anti-surge wheel with a 1.0 housing will perform very well.

 

That's what I thought, thanks for the reply.
I'm pretty sure I don't want to get a 1.15 housing, they are too laggy, but this 1.0 intrigues me as it would make it (IMO) a more balanced turbo.
The part that really sells me on it is the fact that I can still use the EBPV housing as I use it for an exhaust brake and am willing to stick with the .87 housing if I would have to give that up.

Let me begin by showing this picture that I took a while back. At the time the truck was configured with a 5" exhaust, Napa 6637 air filter, Hutch mod, and some fuel rail mods that I installed with a small oriface to bleed air bubbles from the fuel rails in the heads. ITP overboost regulator installed for the MAP sensor. Diablo Predator Tow/Haul tune is loaded into the computer.
4.88 rear axle ratio on a 1999.5 F550.
I took the picture while pulling and aprox 3-4% grade in overdrive, 2500 rpm throttle at WOT to maintain speed. Turbo was definatly earning it's keep because the wastegate is connected. There is so much exhaust volume that it just overcomes the WG and you can see the boost numbers there. You can also see that the EGT is still managable. That's about as high as it used to get.


Ok now fast forward to the present day.
The only change that I have done to the truck is to migrate the fuel pump to the end of the pickup in the tank. The higher the rpm, the hotter it gets at WOT.





The net effect of that modification is that the fuel supply to the engine is so vastly improved that it fuels a lot more than it was originally thought in the design of the truck and the EGT goes a lot higher when pulling a large grade like that. I have nearly the same amount of pulling power on stock tunes as I had on the Tow/Haul tunes before. Between 2000 and 2500 rpm it's amazing the difference.
If I unload the Tow/Haul tune and run stock then it will peak out at 1150 and about 24 psi boost. Also towing mileage went from 8 mpg to 9.5 with no change in cruising speed. I always set the CC at around 68 mph and just get in the right hand lane with all the other trucks. That makes the engine turn 2400 rpm. Any faster and other issues start popping up like a slipping belt from too much load. (I digress)
Moving the fuel pump to the tank was the best thing that I ever did for the truck, but it made the EGT too high to tow the trailer using the Tow/Haul tune without having the EGT go out of control.

 

I just looked at your website with the 1.0 housings and I thought they were wastegated. I don't know if that would be an issue or not with my truck. (read previous post) Any thoughts on that?
Also is it possible to continue using the EBPV housing with the 1.0 housing? (again read previous post. )

 

Someone said " Banks sucks" I have the power pack on my truck. I can tow my 20' box trailer at the speed limiter [94mph] the egts don't excede 950 degrees and I don't even know what turbo surge is!
