Intake Manifold Spacer 4.0l Coming!

So... in the 2nd video am I seeing ported or matched ports in the transition manifold? Yes it certainly looks that way, Nissan port matches from the factory?

 

I did get laid off, but am not a full fledged PE. Just been in Civil Engineering for 9 years and have done aton of different things. Most recent was AutoCAD drafting and design. I am also an IT guy, and have had my own home remodel business. I do lots of everything and never stop learning.

 

AutoCAD still exists?

 

I'm not sure what everyone else considers "lowend" but all the data starts at 2700 rpm. That's not low end to me.
This may yet prove to be a good product for power gains. I just don't see it any significant improvement for the cost.
As far as dyno data is concerned, I like to see SAE correction information along with the data curve. The correction factor should be appropriate for the conditions.
Rough, as opposed to smooth curves, also suggest machine issues.

 

Sound, very sound.

Still Nissan data.

 

Yeah, I agree, it is maybe more midrange, but it does seem to be the range that I am in most of the time so it really helps my truck and driving. The IMS does improve the whole powerband, just more down lower. This isnt necassarily a mod for a rock crawler as much as a for guys towing, running heavy bumpers, or want some extra power. At this point, Im not trying to convince you all, I know the IMS works, just need to get the proven results for the Toyota to back it up and wanted to see what response there was out there.

 

Heck yeah! and Better than ever, I have Civil 3D 2012, as well as Inventor 2011 and it kicks butt with the things you can do for work or play

 

ROFL, the last time I used AutoCAD was in the 80's...

I hear these work too...Dyno graph included...with video of it actually working...

Yeah, I worked with that guy briefly, lets just say he ended up with my plans without asking and started selling them for cheap to spite me. His are handmade and though he claims his skills are up there, they are made by hand and not to spec. One could have a larger intake hole, then one too small. Look at his other items, that's what he knows about and sells. The shiny spacer was a bonus of me not being careful.

 

handmade? like a manual mill versus a CNC? your point is? too small and too large? he states he can hold 5-7 thou, you need closer tolerance from one port to the other? he does have some nice items actually, plus 100% feedback, he also states he matches the ports to a stock lower.

Ebay add quote:

I am a home shop machinist, with 5 years experience, mostly self taught, and have taken classes at the local tech school. I have a good repore with several professional machinists with whom I consult. I work on an Acer EVS3 manual mill, very accurate and powerful. It will tram in anywhere from dead zero to a half thou. It will blank out rough stock to within +/- one thou. The tolerances on the IMS are within 5 to 7 thousandths. All spacers are matched to a stock lower manifold for a precise port match.

 

LOL, but subbed anywho............

 

Toyota could have also dropped the 260 hp 1gr fe in our trucks too but did they?

 

The fact that when I worked with him I saw how he worked. He didnt pay alot of attention to what he was doing at least on this item. Things didnt come out to spec. Sure anyone with a DRO can say they can hold a tight tolerance to the thousands looking at the readout. He may be able to, doesnt mean he does. That info was also added later on, and he did then purchase the manifold too cuz he had a return to fix. Doubt that the specs on a turtleshell guitar pic matter much. LOL There's way more involved than I can say here. I can PM you if you like. He made threats to me and the owners and moderators of the Nissan site Im a member on. Needless to say, he's permanantly banned.

 

I'm very sure there isn't much more that can be said as it is still a 1/2 inch plate, gaining tight tolerance and a manifold spacer don't mix...try again...I don't need a PM, what I need is actual controlled data that Qualitiates my questions. And since you are making these claims in a public forum in hopes for monetary gain I suggest you do the same. Otherwise its just hot air.

 

I should have noted that I was not singling out your product. Sorry for that. The other spacer manufacturer also doesn't give "lowend" data either.

 

well, like I said when I started the thread, the product is already working for other applications, I was testing the waters to see if it interested the Toyota crowd. There will be distinct and definitive data when its ready. I have not made any claims that it works on the Toyota yet but most likely will, that was the guy talking about NST. Dont worry, there are plenty of doubters out there. The world wouldnt be the world without them. Theres plenty on the Nissan sites as well. The people running the spacers are the ones that know they work. It would be strange if noone were to ask questions and want to know the answers. The PM was not about spacer info, I just meant the guy on ebay is not all that appears, that I definitely know and had to deal with.

 

Really?

So the gains that are found with this spacer, which was the inspiration for me to go ahead and see what one would do for a Tacoma, are baseless as well then?

Also, keep in mind that the ACIS system that our factory manifold uses are the principle behind why this spacer does what it does.

From a point of perspective, say a length of runner that has "X" length, was increased, you would over so much length pick up torque. If you were to shorten the length of the runner, from baseline "X" you would lose torque, but pick up horsepower.

Our intake does just that. It has a vane or butterfly in it that is vacuum operated to adjust runner length. Although not nearly as nice and sophisticated as some of the variable runner intakes on high end cars, the principle still applies.

What this spacer does is increase the length of the runners for more torque. You could also relate it to a velocity stack. Short or long. Different applications but same rules still apply.

Different vehicles respond differently to increasing or decreasing the lengths. There is always the point where you will receive dimishing returns. Just have to find teh sweet spot.

 

This is true, but this is also Houston, TX. This place is very humid, and even in the short period of time that it took to swap the manifold, in/out, it changed. Nothing you can do about that, except put the manifold spacer on a motor that is on an engine dyno, in a climate controlled room.

That dyno was done back to back, if you read the thread. Real world. As good as one can get it outside of a lab.
