CJ manifold and E85, who has most NA power?

Now if they could just put the ****ing oil filter in a sensible location and get rid of the 1920's tech hood prop rod, that would be something. My 2007 4Runner had hood struts.

I'm betting Redline and the other hood strut companies are lobbying hard against that ever happening:)

To those who have done the swap, I'm curious how the car behaves differently at part throttle without the CMCV system in place. When I ran a GT350 intake on my 2012, obviously had to disable the hardware and pin the plates open. It was very obvious by the size of the bypass these were never intended for use in full throttle application at any RPM. Also evident in Shaun's video since there was no real loss of power down low without the CMCV active.

Hood struts? Nah, screw it, too expensive.

I read somewhere that for Ford to feature forged rods and pistons vs. typical cast/powder metal in their engines it costs them on order of $8/cylinder extra. Meaning on a typical V-8, it would cost them a whopping $64 in extra material costs to field the motor with forged internals at the factory.

Why they don't offer these types of seemingly marginal upcharges (as options) is either deliberate or just plain dumb.

Who would "opt" for a built motor from the factory with Mahle or CP and Manly internals (any reputable internals maker) for $500+? Hell, Ford could make a KILLING on making money just off the options of it. Then it wouldn't cost us poor souls THOUSANDS afterward to do it aftermarket. But as you pointed out, I wonder how much of it is lobbying from aftermarket parts companies.

I get why they didn't put a factory oil separator, because with some components it's a legal mark on the wall that you're admitting to a design flaw, but with some things....you just shake your head. Like the dreaded grenade overflow tank. It would cost Ford virtually NOTHING to have the part maker darken the reservoir up so it doesn't look like such an eyesore. Peanuts. But instead, we spend hundreds on aftermarket solutions to get rid of the ugly thing. Been that way forever. Gonna stay that way, just seems like a lost opportunity by the car manufacturers.

Back on topic, when is the first set of port/polish 350 heads come into play and what do you think it would be worth? I'm guessing it's not cost effective for the gains we would see.

My reference was that its kinda weak in comparison to a car (11-17 5.0 GT) that cost half as much (base model) with the same intake swap/tuning. Dont get me wrong I love the GT350s just always disappointed at the output.
Ok, let's see the dyno comparisons?
Also, 50rwhp in a small cube NA application is not insignificant, and shouldn't be disappointing.

With good gains of 350 intake on '18gt, I've been wondering who was going to try the reversal, an '18 gt intake on a 350 to gain some torque...since that seemed to be one knock of the 5.2 flat plane to some. Crazy this thing is same hp, NA , as when my foxbody was 302 with bolt ons and single turbo at 11psi.

svtperformance actually did this.

The baselined a 350, swapped a GT manifold (not the 18), ran it with no tuning adjustments, then they ran the CJ with a tune, then the 350 again with a tune.

Pretty much exactly what you'd expect, the GT manifold picks up torque (over the baseline 350) but doesn't make as much power up top.

The GT on a 350 performed pretty much the same (no tune) as the 350 tuned out with 350 intake (in terms of tq).

Anything but JLT, most restrictive by far. Dmark (vendor on here) Also makes a very nice custom CJ CAI as well as porting CJs if you don't already one.

Whatever your tuner likes.

Pretty much this. N/A it's not going to matter much, other than driveability.

If you read the tea leaves, there isn't much published data that's apples/apples on CAI improvements. The stock CAI isn't very limiting (naturally aspirated) so if you remove the "tune" improvements out, the CAI upgrades for our cars N/A isn't worth it (unless your tuner has a preference).

You're talking like 5-7 rwhp for the CAI once you remove out the improvements from the tune over factory tune.

Frpp manifold, monoblade, and cai has arrived. . Anyone else have predictions on estimated gains for a car with headers off road x and e85

^ From what he said earlier I'd say he got there on headers/tune/e85 so the CJ would be the only addition to improve on the 536

^ Considering my 5.0 CJ setup revs to 8200 without issues I don't see 9K in a 350 being a stretch at all.
