Intake manifold spacer? What a gimmick these wont at power at all just a whistling sound that's annoying. These spacers add power on a carbed application but not on a dry intake manifold. Think about it your spacing the plastic manifold away from the aluminum head...what do you gain? Besides basically making a spacer for nothing. With a carb you space the carb from the intake so the fuel and air can spin there for mixing and making more power. Spacers and a dry manifold are a waste.

 

It gives you a fancy bracket to smash off of on the trail too.

 

Manifold spacer, not a throttle body spacer. It shouldn't whistle or produce any noise at all. There have already been dynos on it and it does show some increases. The problem is the guy is claiming low end gains but can't get someone with a stick shift to show what it does below 3k RPM.

 

he needs a pre 2009 to go do it.

 

I think there is still something to be argued for the extra volume of air, even on a dry manifold setup. If the ports are matched up properly it shouldn't make a sound. And hell, if I can get it to produce 2-10 hp at 1500 rpm, a little extra torque, and I can build it cheaply I'll take it.

 

x2, i mean honestly, to have these made ourselves should not cost more than 100-150 bucks.

 

And a stick shift, auto won't let you lug the engine to produce results.

Hopefully we can get ahold of a few used manifolds and make them cheaper than that!

im pretty sure you can. use the shifter to lock it into a lower gear, and run the pulls like that.

It's basically the same thing that Non-Stop Tuning was making for a while. For some reason, they stopped producing them, seems they're getting out of the Tacoma market. They also seemed to have stopped making the lightweight pulleys for the Tacoma also.

 

It won't lock into a gear. Using a lower gear just limits how high the truck will shift but if you put the truck in 3, when you try to lug the engine, it just downshifts to 2 so you can't get good data in the low RPM range.

 

If I can source 2-3 salvage manifolds our test batch should be really cheap. I'll start there, and then get in touch with my machinist to see what he can do.

If you guys keep your eyes peeled for manifolds we have the potential to get this moving quickly. I know a lot of salvage parts move through MA.

 

yeah... i was thinking first gear, but you are right. i think the dyno still takes readings in the lower RPMs even if you use an auto and keep it in D. it should show the power increase over the range of RPM's on a graph.

 

I'm opposed to trying dyno pulls on automatics. Its just a pain in the arse. Its way to easy to get the pulls done on manual and have solid data through the whole range of RPM.

 

I guess you can't use 1st on the Dyno (not a dyno expert, just what I'm reading). Ideally, I guess you want the vehicle to lock into 3rd, lug the engine and floor it to get good data across the entire RPM range. The data that is posted above 3k RPM looks decent but it doesn't do me any good since I don't spend much time there.

 

I've seen them only bake gains on carbed manifolds not EFI. I could have it done as a rapid prototype at school but it wouldn't be aluminum

 

No you can't use first. Depending on the vehicle and the power it makes you select your gear accordingly. Like a auto you'll want to put it in the manual setting 2 or 3 I'm not sure what the second gens have for this. Manual setting may kick down a gear but does it shift? That shift will shift data around. In a manual trans you'll have to pick you gear according to your power level. I've seen 3rd and 4th gear pulls and the occasional 5th. The best dyno runs are the simulated 1/4 mile.

 

That could save us a lot of time. The real issue I have is that I don't have access to CAD, otherwise I could produce really good drawings in 3D which could be converted over for a CNC and maintain really tight tolerances.

Even if you could produce just one spacer with a 4" height, we could then have it cut down and produce a 1/2", 3/4", 1", and 1-1/4" spacers for testing purposes.

What material would it be made of? As long as it is somewhat durable and heat resistant it should work.

 

2nd gen auto here.

Mine is a 4 speed and has a separate spot on the shifter tunnel for each of the 4 gears. I have seen a pic of the 5 speeds and it is the same. No button to select a certain gear (such as my wife's Rav4, has 1-2-D and the OD on/off button).

 

The 2nd Gens have L - 2 - 3 - 4 - D. If you set the truck in say 3, it will shift normal up to 3rd gear but won't go any higher. It will still downshift to 1 and 2 as it normally does.
