bring back the buick manifold :(hell, id even settle for a high flow single t/b manifold :p . we need more in the way of buick parts!

HI Steve,
Just wondering (i think i noticed correctly) why the heat insulators between the plennum and manifold are made from bakelite and not a thermal resistive plastic? Or would it get too hot for the plastic? Bakelite just seems too old school ;o).

I'm kind of funny. I like to be able to drive around normal cruise everyday thing. But when i want to go overtake or off the mark up to 100 i want a good throw back in the seat feeling. Maybe some 1/4 runs here and there also. But not killing all low down take off power in the process:).
I have read some guys with cams who hate driving them around normal, They say they are like pigs. That is something i would love to avoid, But still get as much as i can out of it. I had the idea of roller rockers for some cheap get up and go, And i also like your insulation products, Been looking at them on ebay.
We'll I would probably suggest our higher ratio rockers as bang for buck they can't be beat ;) No only this but they are the best option available if you still want to maintain factory driveability. And the good thing is that we know offer a cam to suit these higher ratio rockers so if you wanted even more power later on down the track you can, whilst still keeping your higher rockers :)

The problem with the twins is that they were expensive to make, and that people weren't willing to pay what we though was a fair price to justify continuing to make them :( In saying this though we may have something in the pipe line :D

The material in which they are made out of is a thermal composite material, which is highly resistant to temps given it's material properties.

The term composite going the description of wiki is

"Composite materials (or composites for short) are engineered materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct on a macroscopic level within the finished structure."

We've gone a composite as it gives us excellent material properties given our requirements instead of over a straight plastic :)

hey mace
what the price for twin throttle mainfold on buick?? as u cant make them anymore ?? will be interesting to know for everyone?? they look so good.

cheers

I should have come to you guys last year. I had a bit of money away just sitting around. I was going to buy some YT RR. Spoke to the guy and all i think he went away for Xmas. I couldn't get in contact with him after that. So there it sat little by little i removed it and ended up going away to Phillip island with friends and blew the lot:bang:.
Yes i like the idea of RR and Cam later. I have always had a figure in mind of about 200kw. Would i be able to reach this easy enough - even without exhaust and exstracters ?.

no, not easily, youll need extractors and an exhaust system to get decent gains from a cam and rockers.

If were to be making them again we would probably be looking at around the $1500, including twin 70mm throttle bodies

hey mace,

with your 1.9:1 rockers, are they worth getting with N/A or are they only suited to forced induction?
The 1.9:1 and 1.98:1 rockers work like a champ on N/A cars :)

That figure is doable, however you will need extractors and exhaust if you want that figure. Bang for buck though you can beat a set of rockers ;)

You're correct in saying this however things like the rockers work surprisingly well on even a dead standard car. Another bang for buck mod would be a cat back exhaust system :)

With your plennum insulators, you have quoted 10% increase in power for the 12mm one and 13% for the 25mm one. 25mm is 2 times (approx) thicker than the 12mm one but with only 3% increase in power (over a broader range). I don't know much about runner lenghts but would i be right in thinking that 25mm is about the optimal thickness for optimal power gains and any longer power figures would start to go backwards? Just thinking about some cars with Tunnel rams.

Forsure i will be adding them at some stage, Only i don't want to go exhaust and all first, Much rather try it from inside out:D.

I have always had the figure in my head 200:D. If i go RR and Cam i will go headers and system. Is there anything else the engine might need to strengthen it up at all ?, Or will it be fine with cam and RR running.
Thanks again for your time.

depending on the zize of the cam you go, youll need a higher stally to bring ur car up into its powerband so it isnt a pig off the line.

then things like leads, CAI, and a decent service, and youll have urself a decent amount of poke for a v6.

next step is diff gears, they wont change your power output, but will increase your accelleration with the loss of a bit of top end. (but when does a v6 have this anyway ;)).

They use a material for the Spacers which is a thermal Composite.

Plastics - at least the common ones, Have operating temperatures that are too low for Engine bay use. Reinforced plastics (FRP's etc) are much more expensive, and still may have heat aging problems.

this gear is ideal for the purpose, and has been used as carb spacers since adam modded his daddies T bucket back when it have 200 ox power.

It's immune to most solvents, has enormous mechanical strength, and its continuous operating temperature is 130 degrees, with peak (short term) temp ability at 155 deg celsius. It can be well finished with standard machining tools and is readily available. It's also incredibley useful as a thermal and electrical insulator.

Teflon and specialist plastics all have down sides, be it cost, mechanical ability or machinability. Carbon based composites conduct too much heat. Trust the stuff - it ticks all the boxes.

Can you tell I worked in plastics and Insulating materials ?

Sounds very good:driving:.

I like the hydratrac 3.46 should have got it when it was $400:hit::bop:. That is true, It's all about 0-120 with a V6 the rest isn't as exciting:p. But that is most of the days driving 0-120.

I have no problem with people using YT rockers either its just we have (as noticed) a good working relationship with MACE and the product works perfectly.

Good question Col :)

Practically speaking I would say your right. However I would still like to go 50mm if I could one day :D

For your requirements you won't need to strengthen anything :)

I had no idea that you ever worked in plastics Andrew :p

No probs Tim. As always I'm sure they'll be happy with them. Can't wait for your charger kit to arrive :w00t:

Good to see the relationship, you guys are doing good things for our 6's.
Thanks for the kind words vxcalais_01,

Certainly easy to work with Tim as we've done so for many years :thumbsup: and certainly don't have a problem recommending his products to anyone, so much so that we distribute them ourselves Vic, which is why you'll see our ads with their chargers on them ;)

Yeah, thats what i was thinking. The plennum would look pretty cool sitting 50mm above the intake. Any chance of you guys sandwiching 2 x 25mm insulators together on an ecotec and running it on a dyno?
