from the wesite:
more power @ 6300 rpm and improve torque in the 4000 rpm plus range. on a stock head and cammed motor, this intake probably make single digit power improvements.

 

anyway. will everyone stop whining, this thread is starting to sound like Neal VS faster150 and it makes me sad


when the intakes get tested. look at the results and then decide if it will work for your application. I'm sure this intake will not work for everyone but I am sure it will work for many others.

I will keep posting what I get from HPS and I will do what I can to help answer questions for anybody. just PM or email me.

 

And you have nothing to lose by showing interest. I would imagine anyone with this motor who has any interest in modifying it even a little bit would be interested in potentially gaining more power. Even if after the intake is tested you decide its not for you then you have lost nothing but a few minutes of your time to shoot an email over. Whatever you expect from the product, theres always a chance, whether that be a small percentage or a large, that it will exceed your expectations. Who knows, maybe you'll be pleasantly surprised. And at the cost of an email, that seems like a pretty good deal. The actual numbers will come in time, but I know if I was thinking of making a new product, I'd like to know what the interest was ahead of time so I knew if I was wasting my time or not. If no one wants it then why bother. But why would nobody want the possibility of adding more power and driveability to their vehicle?

 

Please pardon some of us for being skeptical but why would we be interested in something that doesn't exist. Build it and then show it to us. If I have to pay say $800.00 to gain 10 hp I highly doubt that I would bother. But I digress and you are beating a dead horse. They found an individual to to their testing. We are awaiting the results with baited breath. ZZZZZZzzzzzzzzzz

My apologies. I read the first page or two and then the last page and a half. I just couldn't believe the crap people were giving the guy and the company. Why build something if no one is interested in the idea... the concept? That seemed to be the point to this thread. To find out that if this product did exist, who would be interested. I would imagine most products and services start out that way. Who wants to build a car wash if nobody wants to get their car washed? Who wants to build an intake if everyone is 100% satisfied with the current stock one? I just felt that people were being way to hard and seemed to be missing the point. I felt the need to say something. I too am awaiting the results. I just wish I would have found this thread a bit sooner because I would have gladly shot an email over showing my interest. Hell, I'm always interested in new, possibly better products. I can't believe there are people who aren't.

 

 

Lots of us are very interested and we have said so but we do not want a Mustang intake nor are we going to spend 800 bucks if all we get is 10HP. It will need to be 30HP at least for that price.

Dyno results from my 4.6L Hardball'r and Reichard plates on 5.4L 2v w/ comp 270's and FRPP shorties. Please do me the courtesy of reading the whole thing. It's not as long as it looks and there's lots of juicy details you may care about.

Here's those dyno results. This was on a Mustang 750 dyno. Untuned. First run ever on this motor. 5speed, 3.55:1 gears



So... Realizing that there are some important differences between the 4.6L intake I'm currently using and the coming 5.4L intake (it is not as wide as the 5.4 intake but has the same basic length runners; even if they lack the refined entrance profiles of the new one) and the fact that the adapter plates limit top end flow consider that my current setup is definitely leaving plenty of flow on the table and it's not slouching up there in the dyno graph.

Now then this shows my very first dyno run with the 5.4 installed. Totally untuned it made 279/332 on a Mustang dyno. It was running 11.7:1 AF at the point of peak power and was not running as much timing as it could have been. Subsequently, I did 5 backup runs, 2 more on the Mustang dyno and 3 on a Dynojet 2 days later. All results were within a couple hp/tq for every run and all the curves matched up. Apart from the super cautious tune I was limited to using my 21# injectors and stock mustang pump so that's about as far as I can really go anyway. We saw some signs of running out of fuel beyond 5800rpm and the plates are definitely becoming more and more resctrictive as RPM rose above 4K. On broader versions of the graph you can see a small but distinct leaning over on the HP curve at about 4300rpm. Not surprising considering the angles involved with the adapter plates in place. The new intake will relieve that restriction entirely and help open the top end.

Starting the measurements at 2000rpm and finishing at 5500rpm we see tq BEGIN at 276 @2k RPM. At 3750 It peaked at 332rwtq and was more of a shelf than a curve. Entirely befitting a pickup or my car . The tq shelf shows that I didn't lose all the low end by shifting the peak torque RPM from <3K rpm to 3700+ (as high as 4100 in a couple runs).

There is a good bit left in it. I've got a higher flowing fuel pump and a set of 32#/hr injectors which should solve the fuel issues and some time coming up to play with the tune a bit. As it sits first and 2nd gear are mostly for decoration on 3.55 gears.

This was done with a similar but less refined model of the new 5.4 intake... with an admittedly sub-optimal situation in the presence of adapter plates. The new intake should let the tq peak climb to 4500 without disturbing the low end too much.

FWIW, part throttle performance is more unreal than I'd hoped. It's not just WOT that got the bump.

What say ye?

 

Looks good so far, let us know how the new 5.4L manifold works on a 5.4L truck engine without adapter plates as soon as you can. Thanks.

 

Can you tell us how much of the gain is the cam and how much is due to the intake. I read somewhere that the 226 gives you 55 hp on a 4.6 so the 270 should give at least that much. Add 20 hp from a tune and there is 75 hp right there. Do you have a run with the stock intake for comparison?

There is a complete lack of low end and towing power increases for these trucks running in their normal rpm band.
Why: because there is little to no power left on the table with the stock design.
No improvement with exhaust, because there is none to be made under 3500 rpm.
No improvements in intakes because there is little to be gained over the existing intake tract.
A 4.6L is only 281 cu /inches. Where is the exhaust present sizing and design defficient for the size of the motor?
How much airflow can be gained in the operating range, that would result in a worth while gain for the cost, not much.
This is why a supercharger that forces airflow , does so well.
Optimizing the program is a different matter.

 

the 2 best examples of comparable motors I can think of are stock compression motors with ported heads and stock cams. One in fully tuned trim with shorty headers and stock cams on patriot stage 2 heads made 289/361 with adapter plates in place fully tuned.

Dan Simons original motor made almost identical numbers as mine (more tq) with stock heads and cams and a PI intake on adapter plates dressed with a nice slathering of bolt-on's and fully tuned.

Given the cams I have and the tq peak I'm seeing I know that they're not being fully utilized. I'm betting that with a proper tune and the new fuel system parts to feed it I should be able to chase just about at 300rwhp and probably similar tq to what I make now... maybe a few more lbs. With the adapter plates pulled out of the equation via the new intake there's easily another 15-20hp on tap, possibly more with my cams. Long tube headers should be worth at minimum 15hp more, probably a bit more than that if history is any teacher.

At full tilt with the intake and exhaust bits in place I'm pretty confident that I'll be able to chase 325+rwhp and 345+rwtq out of it on 91 octane and a conservative tune.

Does anyone have a dyno sheet from their stock 5.4L truck to compare?

 

is that a real dyno chart???
