Throttle Body Spacer

[3400-95-Modified]

Yeah I discussed that with TCE but in order to do that on a stock 3100 upper intake I would have to drill out the threads for the 3400 TB and make them through holes... I don't feel like killing my only TB spacer just in case I wish to go back to the 3500 upper.

But you do have a point since that is only $55... I could buy another and just drill it out.

HRMMMMM...

Easier to buy the TCE spacer, its already threaded all the way through on the 3400 bolt pattern. It just doesn't work for a stock TB because of the O ring.

I want a TB spacer just so I can thread a hole in it for my nitrous nozzle... That DOES add power... LMAO

Ohhh hot damn... I could buy an airraid spacer and hog it out to 65mm on bridgeport and then drill and tap it, and BLAM TB spacer for me! all for 129... not that bad!

when?
its april of 09 now

Ottowa's got a lot of good software firms. Maybe they just don't have room for dynos?

[savannaz34]

I'm not implying your dishonest but i dont know you from a hole in the wall so its nothing personal when i say i wouldnt take something off my motor for you to test out...LOL confrontational abit much eh.. Tell ya what whenver I find a dyno in ottawa I'll run some tests for ya fair enough?????

sounds good, I look forward to your results.

Yes, a carb is going to react to more area under it because it effects the fuel distribution.

Don't send me your spacer then. Believe whatever you want. Don't imply I am dishonest when you have nothing to back up that idea. Wait, that would be like believing the TB spacer is making you more power when you can't back that up. Nevermind.

NONSENSE!

Until someone produces A-B-A Dyno runs or actual strip testing you will never convince me a TB spacer on our engines will make a lick of difference, horsepower or torque-wise, and I don't give a rat's arse what your "seat of the pants" Dyno says.

As far as shipping things to Ben, I have NEVER had a problem with his services, or communication, and I'm in Canada as well.

Also every time a spacer is added the torque curve moves up the RPM range.

That is the best part about them for some folks!

Larger TB = larger diameter for air to come into. A spacer is the same diameter as stock, and I highly doubt the .5 - 1" thickness is adding any measureable amount of plenum space. I swapped to a 3500 plenum which has a TON more space than the stock plenum. You have to do something like that to notice anything. If you really got the gains you think from the spacer, I should have insane gains from the large plenum I put on my car......

The spacer isnt just .5 inches..regardless if the throttle diameter is larger vs the throttle body having more volume in terms of depth if they equal the same volume wouldnt they have a similar effect vs a smaller throttle body all together? LOL and ben at wot tech why would i spend money to get my spacer shipped over to you when im not likely to see it again?

Feel free to jump down my throat and call me a liar...all i was doing was reporting back what I noticed since adding the TB spacer to my intake set up. If it felt like it did nothing at all I'd of returned it back to the company within the 30 day trial period. My dad has a 97 cutlass supreme with the same 3100 only bone stock and everyone who's driven both cars has noticed the cutlass feels more sluggish and I his car is in perfect tune, he's one of the most meticulous mechanics i know..Even he said he could feel a difference between the two cars

[geoffinbc]

I tend to agree. Spacers don't work on port injected vehicles. However on Carb and TBI vehicles there are proven gains. Sometimes over 20 horsepower. But in these cases plenum size is very small to begin with. The reason being the manifold is wet and a large plenum volume would allow the fuel to fall out of the air. Also a carb needs a very strong vacuum signal and air velocity to function. An overly large plenum defeats both these things so it really wouldn't work good in low speed operation. So plenum area is always small. Adding a 1" spacer makes a good difference in this case. Also every time a spacer is added the torque curve moves up the RPM range.

[bszopi]

Pedal effort may be due to a possible change in the placement of the throttle linkage due to the spacer... But yeah, the difference in volume is going to be negligible. Like said previously, even if the spacer was 1" thick, and it was larger than the TB size (lets say 65mm as an example =>2.56"), the volume you are gaining is 5.14in^3. That is less than the volume of a SINGLE runner on just the plenum (so not including the lower manifold). Split that across all of the cylinders and you are gaining basically insignificant volume in the plenum overall.

[SappySE107]

Exactly, a spacer doesn't increase airflow. Send me your spacer and I will put it on the bench and show you the results. The volume isn't even worth talking about. Plenum spacers give you more and don't do what you are talking about.
