TT Manifold arrives.

[Wretched]

The Mace Engineering twin throttle manifold for the existing motor arrived late last week, as you can see by the pics.

We'll be working with Silverwater Auto Services to firstly do a base tune on the stock engine configuration, then doing an install story on putting one on and finishing with a re-tune for the manifold for a power figure. After that's all done, we'll get it out to WSID and see if it picks up any speed.

As you can see, it's a big bugger and sports Mace Engineering's ported 70mm throttles as well; and the top is removable should you want to go to town porting out the runners further.

[PantaRei]

Looks good....a little bit to 'boxy' but still ok :)

I'm interested to see what kind of power increase will result from this

[Wretched]

well i should pick up power simply with a custom tune of the existing set up, as it has never been done. It will definitely be interesting to see how it goes with that much air flow with a stock cam and heads.

[Chainsaw]

should be good

[ORIGINL]

would look great polished....

[Wretched]

expecting a set of alloy rocker covers any day now, too.

[LOWHSV]

looks good be interesting to see the difference

[DAZLNG]

looks good yeah and probably a noticeable difference

[Chainsaw]

should be good

[Wretched]

you trying to up your post count, Chainsaw? or did you forget you wrote the exact same thing a few posts ago?

[joe562]

neat apperance would love to see it polished,how about bonnet clearance?

[Wretched]

it's shorter than the trumpet setup scott ran, which 'almost' cleared, so it should be fine.

[Yeti]

How much will these retail for? Are they available now?

[Wretched]

try Holmart or Comcar too, i think... $1200 plus extra if you want the ported throttles.

[MRVNV6]

Looks really nice

[Yeti]

try Holmart or Comcar too, i think... $1200 plus extra if you want the ported throttles.

Thats fairly pricey, it will be interesting to see the power gains both on the track and on the Dyno. Will this fit up to the standard airbox or will you be fitting some CAI?

[Wretched]

not sure yet. whatever works for the next month or so that it'll be on the car. you could pretty easily rig it up to work with the factory airbox, though.

[Yeti]

http://i33.photobucket.com/albums/d70/Chiows/MOTOR.jpg

You could do something like that

[Wretched]

well, i doubt I will, as it is only going to be on the car for 6 weeks, max

[BLO 767]

that would look nuts polished :D i like it, alot actually. looks very high though, but im sure it will squeeze under the bonnet

[bewshay]

that looks nuts

hey Ben is this manifold for the 3800 V6 currently in the VP or is this for the Alloytec?

CHEERS

[GMBT|6]

There some tuff looking TT. I wonder if they could flip the TT, facing the drivers side (for cooler piping) would be great. should make a difference in power.
Where did you get them from (got an website address)

[Cracker]

looks good but for 1200 its a rip off imo.
interesting to see how it goes is there any work done in side the manifold or is that box just bolted on?

[CRZYVH]

thats looks huge well that will be good to see it work with all stock gear

[as_hsv]

whats the height compared to the standard manifold?

looks great and i cant wait to see an engine below it.

[mr_ls1_350]

that looks nuts

hey Ben is this manifold for the 3800 V6 currently in the VP or is this for the Alloytec?

CHEERS

its for the old vp v6

[shamus]

dude...change the Subject Heading... I was expecting to see an Alloytec Twin Turbo exhaust manifold!!!!!

[xcesiv]

The throats look awesome. Will the Throats be on for the Vic Cruise.

[Wretched]

ha fooled you!

[Wretched]

The throats look awesome. Will the Throats be on for the Vic Cruise.

yeah warren

[bewshay]

so Ben y are u spending money on the old V6 when u are getting rid of it pretty soon anyway???
doesnt make sense, but the TT manifold is just BEAUTIFUL!!

CHEERS

[Wretched]

Mace has given us one to test for them and i wanted to do an install/test feature in the mag anyway. the more V6 stuff in the market place the better.

[bewshay]

oh thats what i thought!

good stuff Ben!!

btw do u have any shots of the TT manifold from above and below?

[bewshay]

it's shorter than the trumpet setup scott ran, which 'almost' cleared, so it should be fine.


plus u got the buldge on the VP so it should have even more clearance!

[Wretched]

the bulge is like socks in my jocks, it doesn't extend the clearance, not is it mounted far enough back to clear something like that anyway

[BLO 767]

i reckon you should take it round to bruce, for some more polishing/detail work :p ya know, keep him busy :D

[killuminati]

dude...change the Subject Heading... I was expecting to see an Alloytec Twin Turbo exhaust manifold!!!!!

So was I!!

[Yeti]

That would look nuts poliched but i guess if it's coming out soon then is there any point?

[Wretched]

none really

[SV 304]

Mace has given us one to test for them and i wanted to do an install/test feature in the mag anyway. the more V6 stuff in the market place the better.

i agree as alot of people will be curious to the outcome:eek3dance :eek3dance

[Wretched]

We hit a couple of snags...

The mouting face that the throttles are bolted to needs machining and the bolts holding the plenum to the base require some kind of work like extra length to accepts nyloc nuts or a pin setup to prevent the (unlikely) potential for the nuts to unthread and fall into the motor.

It's nothing real serious or unrepairable, but something we'd need to look at before we can fit it to the engine.

The issue with the throttle is that with the mounting facec not being perfectly flat, the shaft connecting the throttle together is binding, stopping them from closing properly. The return spring isn't strong enough to pull them shut.

We'll get it sorted, but maybe not before the old motor comes out, so we may need to find another engine for it to go on.

[xcesiv]

Im sure there is someone in here willing to offer there car for the trial ;)

[Ricky]

Im sure there is someone in here willing to offer there car for the trial ;)

I thought the same thing and half expected after reading that to have atleast 10 people offering. Good chance for a twin throttle setup though.

[Distance]

I'd happily volunteer mine (thought i'd get in 1st with the volunteer posts) but i don't think a tired old motor with 304000 on the clock is an ideal transplant recipient.

[shamus]

ha fooled you!
so when is the Alloytec turbo manifold coming then????:)

Have you contacted Mace engineering about the problems you are facing? Are they revising their design?

[Wretched]

Have been in contact briefly. there's an email in my inbox at work that i'll read further on Tuesday when i'm back at work that looks like it has a lot of info in it.

Like i said, it's nothing that can't be fixed.

[Cracker]

what happens to it after your finsihed, if i paid 1200 and came up with those problems i would not be happy to say the least

[mr63249]

How much would it cost to get these problems fixed and who could do it? Do you have a rough indication on when you will post dyno results?

[Wretched]

It'll probably go back to Mace for the issues, unless we can fix it here. no idea right now on when we get power figures.

[PuPSV]

i was waiting for something to come up they seemed too good to be true

luckilly i am waiting to see what happens with this before i buy my own (or build one )


someone say trial (nudge, nudge)

;)

[Cracker]

make your own for sure i think. do it pretty cheap under $200 for something like a stock manifold with a box on top and two tbs. need a welder and some one to do some tig welding also you could port it out smooth it untill the cows came home if you wanted. but im not sure maybe the mace one has mods to the runners etc im not sure but it seems very expensive for $1200
be very intertested to see how much power it makes though

[mr63249]

I think its $1200 because it includes 2x 70mm throttle boddies which u can pick up for between $150-$250 each, so the actual manifold by itself would be more like $500.

[mr63249]

Hey Wretched would this manifold be suitable for a twin turbo setup running 20psi?

[Wretched]

yeah, but running 20pounds i would suggest welding the throttles and plenum together

[mr63249]

yeah, but running 20pounds i would suggest welding the throttles and plenum together

Would you recommend getting one custom made up rather than buying the mace manifold and modifying it?

Could anyone tell me where I could get a custom manifold made up to suit twin turbo application in SA?

[CJ_JET]

the manifold looks quite good
hope all the issuies are fixed , and
then will be tested for power gains :)

[Tonsta V6 S/C]

Damn, that look Hot, what's that Twin 70mm TB's and Increased Plenum Volume, should be very interesting :dancingna

Regards

Tonsta

[3SS3]

wow that looks sweet. it will look heaps good when you got it on the car

[PuPSV]

how you guys going ben got it going yet?

[Wretched]

haven't got time to sort it until after the cruises to be honest.

[Distance]

You could try Boostin' Oz in salisbury or i think there's a turbo mob in the St. Mary's area down south road a bit. Don't know if they could fix you up with a custom manifold like that but they might be able to point you in the right direction. Otherwise there are a couple of motor engineers around. John Moyle in enfield is one that i know of.

Thanks for that

[Whit01]

Hey nice manifold! Will be great to see what gains it makes,
ill try it for ya if I can buy it later for a little cheaper perhaps??
BTW: Bet your busting to do the Alloytech conversion now, it must
feel so close!

[Mr.B]

new manifold looks nice and neat, well finished off.. how about a couple of photos of what the inside looks like..?

[MJR_350]

Nice manifold, should look great under the hood.
And from what ive experieced, should make a nice difference.
Id just like to add the the post earlier on the other page about hooking up to stock air box.
I made a TT manifold for my VT and wanted it hooked up to the stock air box so i took it to a mate who plumbes intercoolers, builds turbo manifolds ect and it cost me $200 mates rates for a few peices of ally pipe welded up.
for somone off the street it would have cost near 300+ so there's another expense on top.

[EM1998]

Very Nice there Ben..

Good luck with it. It should definatly make a difference. I recon you will loose some torque though.

[craigvsv8]

nice man i hav been planing on buying 1 of these for my vs to suit the ecotec ofcourse, would b great to c how urs go's b4 id fork out $1200

[freeman]

progress?

[kenny]

Damm I saw TT and thought sweeet twin turbo manifold, but alas it's only a twinn throttle body manifold :(

[GO COMMY]

wats the overall height of the mace ttb manifold (base to top of plenum)
as i want to weld up my own
cheers

[crznvn]

gettin very interesting mate cant wait to see the converion
all the best

[Custom_VS]

Hm looking at one of these for the ecotec, keen to see how it goes. Don't really like the sound of the problems you had with it though...

[Wretched]

It's all good. the guy was suffeing with health issues and wasn't able to put the final touches into it like he does the retail units. we'll get it sorted and do some testing.

[Custom_VS]

OK thats good to hear, and bad (because he is sick). I hope they make good gains because it would be a shame for a manifold that looks as good as the ecotec one to fall short. It looks really smooth, very neat.

I have been trying to get onto their website (www.geocities.com/mace_eng) but so far the page seems half finished and doesnt provide any information whatsoever. Is this an old website or just not finished yet? In particular I was keen to find out whether or not the ecotec versions came with piping to fit it up to the airbox.

[dogsballs]

false advertising wretched, thought you had twin-turbo manifolds ;)

[Wretched]

heheh not yet.

took the Ecotec twin throttle set up to SAS this morning for them to give the once over. If everything is cool, we'll get some base numbers done with a VX S-pack we've got hanging around and do the sway with re-tune... bringing you a story later.

The pre-ecotec unit will go back to Mace next week for tweaking.

[JBA05]

ok good i'm very interested in the outcome of this so i know if it's worth buying one...

edit that is for the ecotec engine i'm keen :p

[sicksix]

man that looks hot...

[PuPSV]

ben whats the go with this

im waiting to see how the buick ttmanifold goes before i get mine

[mr63249]

There seems to be a lot of interest in this manifold, why dont you just give the manifold and i will post results same day so everyone will be happy.

[rujucn]

is this unit 1200 for the manifold and the throttle bodies?

[Wretched]

yes, one and the same

[JST 38L]

Hay Ben just read the article on the manifold it looks good but why the hell did you polish the original engine cover if you were just going to ditch it after a little while ? why not have done something else that you could of used ?
Still came up good but.

[Wretched]

the TT manifold was for the old motor, the new manifold is for the alloytec.

[JST 38L]

im hell confused lol

[Wretched]

I was hoping to do some testing on the old motor with the TT manifold before I sent the car down to VIC for the new motor to go in, but it didn't happen.

Steve at MACE is working on the manifold now and he'll send it back for us to do the testing then. We'll just have to find a car.

[Custom_VS]

If you have the ecotec manifold, you can use my car :) I'll give the manifold a good home once all the testing is done ;)

[Wretched]

got the Ecotec sorted, sorry dude.

[92vpssv8]

did anything ever happen with the buick version of this manifold? im keen to know as ive done a bit of work to mine, and my intake is kinda holding things up atm

[Custom_VS]

howd the ecotec one go? still keen to find out!

[Wretched]

just abou to call SAS about doing the swap

[92vpssv8]

any more news on this ben?

[Wretched]

we were set to do the swap this month, but the owner of the car couldn't get the time off to come down and do it... hopefully late feb/mar

[QUIVR]

bugger.

[Fiver]

Looks good, the size of the plenum chamber will effect performace just as much as having the twin TBs on it, is there any indication of the internal volume comparedto a stock one? This would be particularly important if aiming for gains in a particular engine speed.

[Wretched]

we never got the chance to test the pre-ecotec version prior to the car going to melbourne, but we just finished fitting and testing the ecotec version and a story will be in an upcoming issue of the mag

[wizt]

The Mace Engineering twin throttle manifold for the existing motor arrived late last week, as you can see by the pics.

We'll be working with Silverwater Auto Services to firstly do a base tune on the stock engine configuration, then doing an install story on putting one on and finishing with a re-tune for the manifold for a power figure.

mmm sexy :D

[Chainsaw]

TT Manifold is now in, tune is done :D
stay tuned for a story in one of the next issues of that magazine run by that editor bloke.

[sl33pn_vn]

would it be possible to replicate this manifold using a modified vr two piece for the buick motor?

im wondering how much power gain there would be using a twin thorttle mainifold on a n/a motor and maybe running standard smaller throttle bodies and some porting

just a thought...

[yelo19]

hey ben i was jst wondering do you know if they make a twin throttle body set up for an rb30 motor

[vngenz]

we have been waiting for quite a while now and u say;
stay tuned for a story in one of the next issues of that magazine run by that editor bloke. gees she better be worth it...cheers.

[Wretched]

it's in issue 131 or 132. all designed and ready to go. had lots of dramas with getting the car and the parts in the one place at the one time. I ended up doing the story on my week off. oh well, gotta love it!

[Street VR]

Looks great. Even better if it gets polished up
