Zone 1.5” + Vararam

Doubled up the sensor giving me codes. Drove around for 1/2hr…no codes

Sweet, easy fix then.

I've also used these with good luck to Craig.

2 anti-foulers are working then Craig?

Yessir!

 

[ThunderMug95]

6.4 intake and S&B installed. Jeesh! That was a bit of work. Intake was NASTY.

Better pics tomorrow. I need some hose from parts store. Need to data log and send it to Sean.
Played little guess-a-roo with some hoses, but think I got right. It started and drove fine. LOL

Sad day for my Vararam…4 great years…

 

[Wild one]

Yessir!

Awright i'm glad they panned out for you.

Tellin ya, send her to me she’ll be happy again! Hahaha.

So trying to show my ignorance, but what does the 6.4 intake do for the 5.7?

Much higher flowing intake. Its the best bolt-on intake option for the 5.7. Proven dyno results as high as 30 rear wheel horsepower gains when combined with other mods like long tubes, cam…Im not cammed yet, but I did notice a bit more low end pull.
I need to data log and get my tune revised, then it will be optimized.

I wish I’d taken a pic of how much oil was in my intake. I’ve ran a Billet catch can since 20k, now to 83k. It was shocking. Emptied about 2-3 ounces of oil out of the can when I did the install. Probably 3k worth. So by my math, every 1k our trucks are ingesting an ounce of oil through the intake…and whats that over like 90k…Holy crap.
I need to research @crazykid1994 ‘s mod on adapting the catch can to this intake.

Do you have more/better pics of the Lokar dipstick routing/fitment? I need to order one for mine still. I just bent the crap out of my stock dipstick tube as a temporary job until I had a better solution.

The 6.4 intake has longer "long runners" which helps generate more torque under about 3700 rpm,above that the 5.7 and 6.4 intake manifolds are fairly close.The longer runners usually generate in the area of about 20 to 25 lb-ft more torque off idle to roughly 3700,which is down where you need it,like pulling away from a stop towing a trailer. Above 4,000 there isn't all that much differance between a 5.7 and a 6.4 manifold.In a truck you usually want as much torque as you can get under the torque peak to get the truck moving.
Once the manifolds switch over to the short runners at just over 4,000 there's not all that much differance between the 5.7 and 6.4 intake manifolds,but under that the 6.4 is the superior manifold by a fair bit,especially if it's combined with a set of long tube headers and a tune to optimize the headers and intake

It's not 30 horse power Craig,it's 20 to 25 lb-ft of torque,there's a few dyno tests where the 5.7 intake will make as much horsepower or slightly more then the 6.4 at the horsepower peak,as it has shorter "short runners" then the 6.4 has,but torque under the curve is what your butt dyno feels,and is what gets the truck moving.
Horsepower is just a mathematical equation of Torque X RPM divided by 5252,as dyno's don't measure horsepower ,they measure torque then mathematically convert it to get a horsepower number.Idealy the torque and horsepower curves should cross at 5252 rpm

I was close…kinda…lol.

I will get better pics of everything shortly. I am traveling for work in Texas. I will be back on Wed night. On my headers, I routed down between #3 and #5 primaries. I bolted it to the engine-side brake booster stud with a 90 degree forward bend in the Lokar bracket. Its positioned in a slight curve firward in the the line so as to have a bit of spring force downward. I do not have a clamp on the bottom/block connection. I just seated it all the way in. It took some doing to get it seated. Its a tight fit. I took my time and tapped it in with a prybar and hammer, LIGHTLY, tapping until it seated flush. I yanked on it pretty forcefully, and its not coming out without some serious effort.

[ThunderMug95]

I had to put the bend in the bracket to get the Lokar off of the #5 primary.

Looks great, good job!

 

[Bandit517]

Thanks for the pics of the Lokar! Definitely gonna add one to my next parts order!
