Boss 302 Intake has arrived. Fitment and dyno coming!!!!

[RSKtakR]

Also keep in mind these numbers are with a rigged up intake that may be creating some turbulence by having the air dip down before going up into the manifold. With an intake designed for the Boss intake plus tuning, I think this looks like a worthwhile upgrade.

ya that 45 deg bend right in front of the throttle body isnt helping airflow at ALL.

Im seeing a little loss between 3500 and 5500.
so a few ft/lbs down over 1000 rpm of usable RPM

you are correct I misread the graph but I would still like to not see that drop of what looks like 10ftlbs plus through out the midrange, I will wait to see what tuning can be done

 

[captdistraction]

I'm still wholeheartedly getting one. For what I want to do, this thing is money.

I think with further tuning and revision of the inlet CAI, this combo will net the results everyone's expecting to see. However a 52HP gain at 7500 is far from meaningless, for road course work that's going to be awesome down a straight.

The torque loss just doesn't seem as extreme as some make it out to be.

So you wouldn't be happy with a Boss 302?

 

[GeorgeInNePa]

WOW I can't wait!!!!! My car is going to be always in the higher rpms

 

[Twinscrewgt]

I've been shifting my car at 7300 ever since I got the tune from BBR. No problems at all. Several others are shifting at 7500 without any problems.

7500 rpm with a blower

 

[GeorgeInNePa]

I suspect with more tuning we will see it making more power starting in the 5k range. But overall, thats the kind of shift in powerband I expected.

With the rod ratio of the engines it seems like we should be able to take them up to almost 8k, but there must be some other limitation I dont know about, or nobody has really tried because up until this manifold has existed there hasnt been much reason to rev that high...

Also, you guys need to look more carefully at the voluem difference within the RPm range the engine will be in while racing. Id have to do som e gearing calculations, but assuming that youre not dropping much below 4500 when shifting up at ~7500 rpm, the torque volume lost below that point means nothing.
From 4500 to 5500 the loss in volume is pretty small, and the increased volume from 5500-7500 is substantial.
And thats still with what I expect is tuning that has yet to be optimized. When they start actually increasing peak power the volume will get much, MUCH larger.

If you are shifting at 7300-7500, the only time the engine sees 4500 is in 1st gear...

Anyone complaining about losing 10 ft/lbs of torque down low obviously has no clue. That is something you'll never, ever feel and won't be the reason you lost a race. 52 rwhp is most certainly something you'll feel, even if it is up top. I'll also be interested to see what type of mid-range gains can be made with additional tuning and a non-rigged CAI.

I cannot wait to see this intake on a motor that has ported heads and aftermarket cams. I'm willing to bet this thing makes 500rwhp with those items.

The correct hose for a 2012 Boss is part number CR3Z-9B659-B , list price is $94.83

Is that the plastic elbow?

 

[kdanner]

The whole hose to the airbox, including the flexible joint.

Yah, thats was just an an analogy.
Id have to do the calculations to see exactly where your dropping down to, but I figured it was not very low for most of the gear changes, maybe in the 5ks?

 

[GeorgeInNePa]

We'd have to add a fitting for an auto car. It looks like there is no provision for it since the BOSS is a stick only car.

Correct, or get the hose assy that provides vacuum to the brake booster for a manual car, which would eliminate the extra connection. The Boss has a unique part number for that also.

I would love to see an 8000 rpm beast 5.0 motor with a 4500 stall in an auto with 4.56 or 4.88 gears and a real slick. As for the torque production this was already foretold by Ford it should not be a surprise. When you have an engine as optimized for airflow with heads as good as the 5.0 there isn't going to be 30 or 40 lb ft in the midrange just laying on the table.

As I think I and quite a few others have said, to get to 500 rwhp and to really start optimizing airflow improvements from cams and heads your going to need to spin 7500 plus rpm.

 

[KonaGT]

In order to really take advantage of the Boss manifold you would have to be shifting at 8k plus at the track

i do have a clue, 10 ft/lbs over a 2000 rpm range is more valuable to me than 52hp for 300 rpms

Why?

 

[Whocares05050]

Yeah, seriously. I bet you wont notice that differance when the RPM climbs so fast. Unless when you race your shifting @ 4500 rpm. Even if you were road racing your still in the upper rpms.

 

[PBstallis]

having an extra 52hp at your redline really does nothing, if it was 52 hp at say 6500 or 7000 I would not argue but it isn't its right where they shutdown on the dyno, I only responded back on this thread because I was called and felt I had to respond with my reasoning

With all due respect you are completely wrong.
