FEELER: 2 inch thick 2.7 intake manifold spacer

Haha well let's just say I'm lost at why anyone would pay anything for literally no positive gain. And I know you are well aware that just because the hours in r&d were put in doesnt make something worth a lot of money. Results are everything. I'm glad that you showed some results cause I know it sucks to put time, effort, and money into something and it turn out worthless.

 

Huh? My first sentence isn't referring to tooter. Read young one. He asked me a question

 

I'm interested in finding out more.

 

I see a personal gain for me from his dyno sheet that fits my driving style.

 

That's one reason I went for the absolutely thickest spacer that would fit within the available space. To make damn sure that it would actually yield a measurable difference. Even at 2 inches the difference is already modest enough, so at one inch or a half inch, the results would have been unconvincingly anemic.

And since everything else is essentially the same except for material costs, a 2 inch spacer gives you the best bang for the buck.

 

Ok.
I'll add you to the list. It's not a commitment to buy, just an expression of your interest to help me decide approximately how many spacers will be made.

 

I'll also add your name to the list.

 

If I was keeping my truck I would be all over this.

 

Did you ever decide if it helped/hurt your mpg?

 

Ok. I'll take you off.

 

Hadn't done that yet, but just now added up the mileage logs. It's only a very slight increase of 1.6 mpg.

533 miles @22.36 gallons with no spacer 23.8 mpg
519 miles @ 20.388 gallons with the spacer 25.4 mpg

I should be able to get a more accurate profile with more miles driven. From the results, at least I'm sure that it didn't hurt the gas mileage any.

I think the most interesting effect doesn't show up on the dyno charts because they can't go that low. It's starting out slipping the clutch from a full stop. The engine pulls nicely at very low rpms, even below idle speed without stalling, so it doesn't hardly take any throttle to get the truck moving, even with my 5 lug's really high street 3.31 final gearing. This makes it really easy on the clutch, and I think that over time it will last longer.

 

I have the 4x4, I wonder if it would lower the tq curve even further bc of gearing.

Did you notice a mpg difference after you added the lce header?

 

Gearing can't alter the torque curve of the engine. However, gearing can alter how your truck performs. Torque feels different than horsepower.

Horsepower is the ability to gain rpms rapidly... the ability to accelerate.

While torque is the ability to hold a given rpm under a heavy load... the ability to pull.

Couldn't really tell...

... because I bought the truck on April 13th
and installed the header on the 19th!

 

Sooooooo interested for the right price ( I'd prolly pay in the 100-200 range)


I do some mild trailering and a lot of driven like a bat out of hell so I'd love more torque in the lower rpm

 

Yea I guess not really lower it but starting/crawling would be even easier than a street geared taco.

 

Absolutely...
...because with lower gearing, the engine has more mechanical advantage (leverage) over the wheels. For heavier vehicles with heavy large diameter off road wheels, lower gearing offers a tremendous advantage and makes far more difference than any spacer.

 

Ok. I'll add you to the list...
It's important to understand that the absolute torque peak itself is not increased. That same amount of torque just becomes available at lower rpms which would be of some help when you're pulling a trailer.

 

that's the gain? pass.

 

That's fine. It's always good to know that your expectations aren't met before you buy anything. This is just a simple bolt on part. Forced induction will give you the power that you want. That will meet your expectations.

This shows exactlly what gains are. Just 2 ftlbs. more torque at the peak, and the torque peak comes on 250 rpm lower.
