Both before and after videos are 1250rpm start WOT run in OD with the torque converter LOCKED and run to about 2250rpm. Speedometer is in km/h.

The 4th gauge down is the fuel pressure, it's the only one you can't see clearly.

All mods remained the exact same between both runs. timing, etc, even the weather was very similar

Important mods/info that remains the same for both the before AND after videos:

Before video with s362/65 and unknown exhaust housing: I think the housing is a 14cm gated housing because it looks very similar in size to the .85 housing of the A4000. wastegate is welded shut

12-13 seconds to go from 1250-2250rpm
1300F and rising at 2250rpm
33-35psi @ 1500rpm
1750ish rpm ballpark surging, and fully spooled @ 47psi by 2000rpm
light to moderate driving is very clean even at very low rpm, and quick to spool at all rpms
WOT once spooled has a good haze still
WOT peak PSI @ 47psi

After video with ATS A4000 (64/70/.85):

13ish seconds to go from 1250-2250rpm
1200F and rising at 2250rpm.
16-18psi @ 1500rpm
1750ish rpm ballpark surging, and fully spooled @ 46psi by 1900rpm
light to moderate driving is a little bit hazy, especially at very low rpm, and quick to spool above 1500-1600. and sluggisg below that
WOT once spooled is very clean in my opinion
WOT peak PSI @ 46psi

5-60mph run with 5000 lbs in the bed, 12000lb gross weight

http://s113.beta.photobucket.com/use...8f1a1.mp4.html

Things heated up a bit in OD because it hovered around 1500 rpm for so long. I have the transmission controller set to shift quite early under light throttle. Even with the A4000 it's fairly smoke free at light throttle down low in the rpms

 

I will also add a video of a 5-60mph cruising run with 5k lbs in the bed. gross weight with the truck @ 12000lbs. just so people know what it does with a little weight behind it. It's accelerating at really low rpm in 3rd and OD so it heats up a little bit because in OD it stays around 1500rpm for a long time. Video soon...

 

Second video 14ish second mark, surge? Crazy noise and gauge readings!

Do you have head work done? I'm sure I've asked but Coors is taking up my memory right now!

 

ya it surges pretty good. If I'm not careful I can make it surge so bad it straight up barks but normally it would downshift way before that ever happens. I just put the tranny controller in dyno mode so it wouldn't downshift for the videos

The first video with the s300 didnt do it as bad but I could make it do it every bit as bad as well if I really wanted to

I've resolved to the fact that it's not the turbos, timing, or anything other than the supporting mods (manifold, cam, turbo blankets etc) making the turbos spool too early and surge simply by cramming more air in than it can handle down low.

No head work. I'm thinking if I had a ported head the increased flow would make it so it wouldn't surge

If money ever allows I will send my head away, or if a reasonably priced ported head comes up for sale and I have the cash I'll grab it.

EDIT:

Added the drive up to hwy speed with the weight in the bed to the original post. Normal acceleration blah blah blah

 

Interesting, thanks for the information. I've got a little head work done. Thank you for the time and effort in posing some videos and all of your information. I hope to have you some more information soon, waiting on primary, camshaft, ANOTHER set of pistons, and figuring out the injector lines.

There was a dude on CompD with a slick looking 3 piece intake he made, I kinda got the hankerin to make somethin like that now. It looked super slick!

Sorry I gotta say looks really weird looking at that blue oval, it moves my eyes off the gauges. I honestly had to watch the videos 2 times to just look at gauges.

Any videos of smoke trail coming soon? Sorry to ask just kinda want to see how quick and well it cleans it up.

 

ya no worries, you're welcome.

As a single this a4000 should be able to support 550-600hp. Technically it should flow enough air for that. I'd hate to see how hot it would get but I guess that's a different story.

As far as intake. I would think the stock log on the head is fine right up to a healthy amount of power. There are however a few little things that can be done inside the log to help flow just a bit.

Aside from that I think a twin ram intake is nice, but rather unnecessary unless you're making pretty huge power. Part of me wonders how a cold side 3.5" intake pipe would work out. I run a second gen intake plate which has a bit bigger inlet on the plate and the 3.5" stuff would, or could, maybe prove to make some sort of a difference. Not sure on what it would do exactly...

As for the blue oval... ya I usually seem to forget that it's a ford with a Cummins most of the time until I catch people eyeballing it when I drive down the road. Or they come up to me and start asking questions about it.

I can probably post videos of the tail pipe, and eventually dyno sheets but none of that is going to be for a while. I am currently out of town for work and won't be back for another month minimum

 

Thank you very much. I'm in no rush, my truck sits on jackstands 99% of its life. Have you noticed it cleaning up the smoke? I know its hard to look at road, gauges, traffic, Johnny law and a tail pipe. While under a full throttle run. I appreciate all if the information you have provided for all of us and taking the time for videos, you should tell Aurora you want some advertising money!

 

HAHA the day ATS sends a check to me I'll just about fall off my chair.

As far as smoke goes, it's nothing more than a light haze out the pipe with the a4k at WOT once it's spooled up. MUCH cleaner than the s362 at WOT. At light/medium throttle while accelerating and low rpm it gives a little shade of smoke out the pipe but nothing to write home about. At hwy speeds cruising it's completely clean. Infact while cruising, no matter the rpm it's completely clean. I can cruise in OD at 1250rpm and it's clean but once I start up a hill or begin to accelerate it hazes just a bit.

At part throttle daily driver stuff the s362 was better, but that's to be expected. I'm still actually quite happy with the DD quality of this charger.

This charger in this setup still lights WAY faster than the s362 did pre rebuild (before the ATS manifold, cam, blankets etc)

 

I have had about the same experience with the A4K...I would definitely recommend one if someone was willing to put in a cam or do some airflow mods. It definitely moves some good air at high rpm/boost.

 

Agreed.

I do want to provide an update on this charger.

It makes a lot of heat below about 1800rpm and doesn't like low rpms. It makes a fair bit of haze under 15psi with light to medium acceleration. The smoke begins to clear above 1800rpm.

I recommend it for an auto truck as it doesn't smoke much at all at any rpm in my setup until the converter locks. Locked it smokes often unless you're just cruising. That or if you drive a stick, keep the rpms up and you'll be fine.

Realistically, it's not a great match for a ve, more of a ppump charger because those can turn more rpm and make more usable power higher up. If I could do it over again I would go with an s362fmw/68/.85 and have a race cover machined for the fmw compressor. Then again, that would be a real expensive single!

This charger needs a hamilton 188/220 cam to make full use of it for a dd ve motor that doesn't see high rpm use.

Great track turbo though I think. I hope to hit the dyno once the new head is on and I can hopefully eliminate my surging.

In my setup I do get great fuel mileage though. 20 US mpg if I keep it to 65-68mph

Another update. I finally did my timing. Threw the ip to the head. I'm a tooth advanced as well. Seems to have made a big difference in low to mid throttle smoke. Haze at idle is a little better too. I'm actually really clean from zero boost doing a wot run while cruising. Seems to have helped my surging a bit too. Afc now needs more fuel I think. She runs good but a little tuning will make it run even better.

EGTs, although it smokes less, are actually higher. Seems strange to me but whatever.

To sum it up, now that I've done my timing, I actually like this turbo a lot more. Except for this extra heat I'm making for some reason. I don't tow so I don't much care about that though.
