HE351 code for me78569

Since I installed this turbo my EGT's went WAY down, and I'm wondering if it's something to do with my pyro placement that changed.. I can pull pretty darned hard and not go over 1100, I even removed the fuel plate completely and still hardly get over 1200.  Truck doesn't smoke much unless I really tromp on  it at about 1400 RPM without building some boost first.. I think if I put an AFC controller on it I can make it pretty much smoke-free.

I can't watch the videos from here, but will try to remember next week... How much smoke is 30%?  I'd figure 5% would be pretty much invisible though.

For passing smog  tests, try a much more aggressive boost curve to build more boost earlier, in addition  to defueling.

I have no idea what %30 looks like.  That's what I really wish I knew.

Actually the truck smokes worse down low if I have an agressive curve.  Power is better, but smoke is worse.

I struggle to get egts over 1200*f

Pretty Graph time.

My quadzilla app has been updated to do data logging.  short run to prove it works, > %30 throttle up to ~30 mph.

[Rx7man]

You're right.. it is pretty... nicer than what mine are

[me78569]

I finally get the logging working and it start snowing haha.  Can't use the skinny pedal.  Oh well.

[Rx7man]

4 wheel drifts at 60 mph are fun though!

[me78569]

haha yes they are, but people frown upon that.

[Rx7man]

hahah, yes.. Pedestrians, cops, and passengers especially

[me78569]

well I did get a chance to do a 3rd gear pull.  I pretty much flooded the turbo with fuel, but oh well...had I rolled into the throttle it would have built boost much better. 

Impressive thing to note from this graph is the EGT's.  Everything turned up my max temp in 3rd was 1200*f

me78569 look familiar.
Yes it's your old HE300 housing.
Ended up getting a 58mm wheel for a hx40 and milling the housing to match.
Then the map width enhancement slot was off so I made one that is adjustable.
I have alot of time in that housing but look forward to testing it out.

[me78569]

wonderful to hear!

I actually seen a 300ve on ebay the other day and thought about the housing haha.  small world.


Nice to see you could mill the housing.  and pics of the process? 

[Rx7man]

Only went to 58mm?  looks like nice work.. While we're on the topic.. how are you balancing it?   As I was saying earlier that BD won't put a bigger wheel on a 351, I do have the tools that I think I could recut the housing for the wheel, but balancing would be a problem

[hakcenter]

AFAIK everything is neutral balanced ?

[65fpvmustang]

it's actually a smaller housing and wheel where it got interesting is on the exducer.
Smaller dia. but taller blades so the housing had to be cut back for clearance. Inducer stayed 58mm but the length is different so the mwe groove ended where the comp wheel started. https://www.youtube.com/watch?v=jRrLdXGi2YQ

That is possible, but with the sensitivity of these things I don't know if that's enough.

Wish I could watch the vid from here
