You went for a HUGE air filter and it is tucked in a good spot. Most guys stop giving a crap at the point and short change the power. Can't wait for the video.

Looks great...can't wait to hear your impressions when it's rolling. Nice job!

I think I pretty much have the install done. Need to get some running time on it.

Not sure I am super excited about the cross bar. Really close to the intake but should be OK. May install another one on the back side.

You do nice work, however given the height of your intake, what if you made a diamond shaped engine bay cross bar with two tubes, one that goes over the front of the intake/throttle body and then one behind it?

Very difficult to find any room in the front of the throttle body. Very little room under the throttle body. Might add a second one behind the first and tie them together.

Maybe I can fit another smaller bar under the throttle body. Need to check.

Hood slopes down towards the front so less room for cross bars...

Looks awesome. I'm really interested in that LS style intake, coil on plug/distributor-less, and how the tuning goes.

 

[rcmbronc]

So right now I added a second shock hoop. Looks like it will work.

Doing some tuning on the EFI system's self learning. Getting much better. I can say the little bit of driving I did with the truck it makes plenty of power. Might be a bit oversized on the throttle body, not sure yet.

Throttle body- rpm tip in hard to control?

 

[rcmbronc]

Not sure yet. Need more driving. Little sluggish down low but also need to work on the tranny programming.

100mm TB correct?

 

[rcmbronc]

Holley 102 Sniper. They also make a Holley EFI 105 with a low flow taper for better bottom end. A bunch more money though.

Tapered...that sounds like the ticket!! All the "cool" stuff is mega bucks!!

I am running an 80mm TB and with changes to my linkage thanks to a couple guys Broncobowsher and an AZ or Colorado guy it helped with feathering in on my throttle at 750-1100 rpm.

Lars helped a bunch also and I changed my pedal ratio on my side of the firewall. All these helped with throttle application off idle to 1200 rpm.

My 80mm TB isn't restricting my 600 hp so if you need to you can step down some and not lose any HP I would imagine.

Keep us posted... enjoying your thread.
