Speedo reads about 5 mph faster.

Runs pretty good, my buds 7.3 auto is only 1 sec faster and it has intake exhaust tune and stage 1.5 injectors

What do your EGTs get to on a run like that?

My biggest issue is getting power to the ground. The trans shifts awesome but the torque converter is too loose, just slips on a hard run.

No egt or boost gauges. I try to keep out of the throttle other than those vids, until I can get some gauges.

[spencerdiesel]

Yea the stock converter is a power sucker. I've heard that an auto equipped truck will lose near 25% to the wheels

I think manual trucks lose around 15 to 18%

[spencerdiesel]

I noticed a hair more top end when I put my piston pump on, with your fueling did you notice a difference? Is your timing advanced any?

[79Powerwagon]

Yeah timing is bumped to the head.

It did make a pretty substantial difference in top end power with the piston pump. But I bypassed the stock filter and ran bigger lines at the same time. Has much more top end git up now. Once again, torque converter just slips though.

[spencerdiesel]

I noticed it ran a lot faster in the 2nd accel vid, was it a boost launch or did you tune out some low end fuel? In that video it's actually as fast as the stroker

[79Powerwagon]

2nd one was from a 10mph roll.

It doesn't do bad for nearly stock.

Finally found a usable HE351 for a good price, $120. Going to stick new bearings n seals in, open up the wg and run it.

[spencerdiesel]

Awesome. Another vid once you get it on?

[79Powerwagon]

For sure.

Went through it today, used the exhaust housing off the junk he I had, as the one I bought was pretty rusty. Opened up the wastegate to one inch.

Need to get a downpipe figured out and then I'll stick it on.

[spencerdiesel]

How many psi you going to WG at?

[79Powerwagon]

I turned the actuator solenoid into a plug (hacked off coil and brazed it shut) so until I get gauges I'm going to run it at the factory 20-22 psi. I'll add an adjustable elbow later on. I'm sure the h1c is currently running around 30 psi, but I don't want to chance it with the HE.

After that it'll be time for a new HG, studs(or bolts), 60 lb springs, 366 gov spring. Have a 66mm turbo off of a C9 I might try to hang next to the 351.

[79Powerwagon]

Hacked off the flange from the rotted 351 ex housing and welded it onto some 4" pipe, cut several angled sections, homebrew downpipe.

[79Powerwagon]

Got the turbo on and half a downpipe done. Charge piping made out of exhaust pipe, not exactly ideal.

Seems to work well. Need to finish the dp and crank up the boost
