[Buick] Throttle body spacers

[V6Q]

hey fellas due to the lack on info on tb spacers for buick motors ive decided just to make some and see what happens, im hoping it has the same/similar affect as mace's plenum lid spacer, ive made 2, one between the tb and the elbow and another between the elbow and manifold, my throttle body is a smoothed and polished standard 60mm, there not massive, only 8mm each, im converting a vp v6/t5 and diff into my hq ute and im not sure how much space im going to have until its all in hence why ive started small, once the motors back in i might make 2 more somewhere from 12-20mm each depending on what fits,
if anybody around Dubbo nsw wants to be a guinea pig to see if theyres any noticeable gains id like to try them out, anyway heres some photos, not much to see but never the less

here they are done, mocked up to a s1 vn motor

cheers

Wont make any difference because its steel, might even make the heat issue worse

yeah i know ill test them before the motor gets too hot and the heat spreads, just to see if theres any benifits to warrant going any further with them, if nothing else theyve increased the plenum capacity a tiny bit lol

Good idea mate but the heat will still be there try some plexiglass

 

[V6Q]

as soon as i can find someone willing to try them ill go from there, mates got a mill so ill use that and make them from something else
anyone in/near Dubbo Nsw want to volunteer?

The only two replies and there both going on about the problem with heat. Spacers are not designed to reduce heat, they are designed to increase volume and or length. MACE plenum and manifold spacers have an added bonus of reducing heat transfer (being that there made out of a heat resistant material).

V6Q, There should be a small gain in throttle response, and possibly the slightest gain in torque.

Make em out of compressed cardboard/mdf and thatll solve your heat issues. I dont think youll get much power increase from these tbh.

Back in November 2007 I see Mace put a twin throttle manifold on a VX V6 and then got Dave at SAS to spend a few hours doing a dyno tune and ECU re-map. The manifold and tune COMBINED got the owner a total of 5 killerwasps. The article did not separate how much of the 5 kw was due to tune and how how much was due to manifold.

Nor did it say what the cost was to get these 5 kilowasps........The article was in November 2007 Street Commodres magazine.

If Holden had fitted these at the factory I cannot help but think that there would be a sticky on this very forum about how to remove these spacers so that you get more power and better fuel economy or something..............

There not a restriction, so there would be no need to remove them.
