throttle body spacers?? input please

[jayson427]

i was looking at a throttle body spacer from horsepowerfreaks.com and i was wondering what others thoughts were on them and if anyone runs them or not? its almost $200 so i wanted to know if they actually work and are worth buying. my bottom end could use the gain but was unsure about them. thanks

I have never seen any one prove they actually work or get noticable gains. Yet they still sell. I'm skeptical for their worth especially at 200 dollars I think it can be better spent elsewhere.

i did it and didnt see a gain worth 200 bucks. absolutely no way. save your money and through a turbo on it

 

[bryanwheat]

Waste of money.

well i have a OBX throttle spacer and a cold air intake stock cat and4-2-1 header all 2-1/2 inch piping. so you need to see the slight gain with all stock. but its only very small gain a m.p.g so if ita a daily driver yes..mod up then no!!

 

[jayson427]

the only thing stock in/on my motor is the crankshaft. i just wasnt sure if those spacers actually make the air smooter as it passes through the intake manifold or just the same with out the spacer.

Full intake and exhaust nets 5hp and that actually does something. A spacer wont do anything.

You'll actually gain more from duct taping a leaf blower into your intake. It gains 15hp on a 4cyl ranger.

Waste of money imo

i have aftermarket intake and manifold and full race exhaust now. just trying to get everything i can out of my motor and seen that spacer. im currently running a 55mm tb with an obx intake manifold if i go bigger on the tb what would that do with 19lb injectors 10.5 compression and stage 2 camshafts? i havn't been able to dyno tune yet so im seeking anything helpful for making the most and efficient power on my n/a set up

Throttle body spacer wouldn't do crap really.

Maybe a phenolic manifold spacer/gasket would gain a few horse power on the top end (maybe 2-3).

Throttle body spacers are awesome....they can net you a lot of hp....I have heard of netting up to over 100+hp....after you connect the NOS system to it.

Most spacers that are worth getting are ones that are prefabbed because you are adding NOS. The spacer alone does nothing.

I guarantee if you had a logger and put a spacer on your car you would see no difference. Don't waste your time and money on it.

I put one on my 5.7L Blazer and I def noticed a difference.But on our cars the air makes a sharp left turn through our intake,making the spacer usless.Maybe if they designed one that went between our runners.still would not be very cost effective.

 

[jcart953]

I have a phenolic space, and it cost like $40 so im not to sure why yours is $200. In any case I did notice the intake pipe was much cooler after I put the spacer in. I did not however log any temperature changes at the time and will not do so until my new manifold + throttle-body comes in. Whether it gains anything special meh, but will see.

 

[jayson427]

It was the only spacer I seen on horsepowerfreaks

I've written about this extensively in the past -- search for it. Throttle body spacers are a carry-over from carburetor spacers. Carburetor spacers had a purpose and would yield appreciable results, throttle body spacers won't.

 

[jayson427]

thanks paul, i kind of figured it wouldnt do any good but i wanted to see what others thought.

 

[jrohner]

I like how they even sell throttle body spacers for diesels, that alone proves how much of a gimmick they are.
