Mace Intercooler purpose and difference?

If you never plan on going past 10psi on an M90 I would stick with the 1.9's from a bang for buck perspective

Cheers
Steve

Fair call knowing me I will never be content haha, fornow I am eyeing the 10psi upgrade, just once I fix my belt screech (replace all dummies, auto tensioner and coupler to stop it rattling (by the way do you sell couplers for the s/c, worth asking)) once i fix that and I get myself a good boost guage (if you know of any reliable ones let me know) to see if i am losing vac then Ill got ahead.

Ill make sure everything on that engine is 100% before I start doing any major mods, its the 98% problem, people have an issue with the motor and mod it, will have a greater problem, for instance if I put a 10psi pulley on with my s/c rattling (damaged coupler) due to 10% more shaft spin (apparently) it will damage the internals causing more problems.

Anyways Ill get back to you when I fix these issues.

Thanks Steve for your advice Ill hit you up if I have more qns,

Andy

In all honesty I would just stick to the the 1.9:1 ratio rockers and 10psi boost upgrade kit. This alone, in conjunction with a cat back exhaust, will eat LS1's for breakfast under real word conditions (between traffic light)

We also sell the couplers

As for a boost gauge I would recommend only recommend VDO gauges. Good enough for car companies (your current dash) good enough for aftermarket. Here is an example of one below though it doens't take into account vacuum but you get the idea.

Smart man

No problem Andy.

That is good to hear, sounds too good to be true, but then again it is possible, it would catch me on top end. Mind you what mod components make substansial tourqe?

Sounds good 10 Psi 1.9:1 rockers (will I need those pushrods you supply for 100$, because it pushes it up to 595 which the 1.9:8 are 100$ on top of that therefore 200$+ and I am getting something I can play with), also what are those pushrods for?

Anyhow what are the 1.9:1 rockers good up for in terms psi, as in when will I need to change the rockers in order to see substanstial power/tourqe difference according to my higher psi pulley (if you know what i mean?)

May I ask what your couplers are going for ($ wise)? And are they Polyuthurine Material not nylon which is what stock s/c m90s use supposably.

Nice, wish VDO had a bit of character with their guages but then again, if they work I am happy.

Cheers,
Andy

“That is good to hear, sounds too good to be true, but then again it is possible, it would catch me on top end. Mind you what mod components make substansial tourqe?”

Top end, past a 100ks, a modded LS1 would start reeling in on the L67 but under real work driving conditions at around legal speeds I think you’ll be hard pressed to find many cars on the street that can keep up with an L67, more so with bolt on mods. Bare in mind we make and supply parts for LS1,2 and 3 etc so I’ve been in a few

“Sounds good 10 Psi 1.9:1 rockers (will I need those pushrods you supply for 100$, because it pushes it up to 595 which the 1.9:8 are 100$ on top of that therefore 200$+ and I am getting something I can play with), also what are those pushrods for?”

If you stick with the 1.9:1 ratio rockers then you won’t need pushrods. The 1.98:1 ratio rockers are $55 onto of the 1.9:1 ratio rockers with pushrods. The main reason for the pushrods is to increase clearance between them and the cylinder head, as the higher the ratio the closer the pushrods get to the cylinder heads.

“Anyhow what are the 1.9:1 rockers good up for in terms psi, as in when will I need to change the rockers in order to see substanstial power/tourqe difference according to my higher psi pulley (if you know what i mean?)"

If you want to play it safe I would just stick with the 1.9:1 ratio rockers as they are a good all rounder.

“May I ask what your couplers are going for ($ wise)? And are they Polyuthurine Material not nylon which is what stock s/c m90s use supposably.”

We sell both styles of couplers; however I’m more for the genuine couplers, despite not lasting as long as the aftermarket couplers. The reason for this is that are more forgiving to any shock loading then the stiffer aftermarket items. This can be a problem as there have been cases where the stiffer couplers have broken the pins which locate the coupler in place. As for prices we sell the genuine and aftermarket couplers $40 and $55 respectively.

“Nice, wish VDO had a bit of character with their guages but then again, if they work I am happy.”

You mean something like this

SWOOSH 52mm JDM Sound Active TURBO BOOST (Psi) Gauge - eBay Other, Gauges, Car Parts, Accessories, Cars, Bikes, Boats. (end time 15-Jul-10 01:15:32 AEST)

To avoid buying a gauge twice, best to stick with a quality accurate item first time round. Another brand which is good is Stewart Warner

Well that is pretty much summed up,

I need to contact you about your coupler on pm, genuine sounds a little more trustworthy it seems then.

Stewart Warner Gauge 114547-Vacuum/Boost White 2 5/8" - eBay Boost Gauges, Gauges, Car Parts, Accessories, Cars, Bikes, Boats. (end time 13-Aug-10 11:56:28 AEST)

looks good to me.

Not a worry

Hey Steve,

Needing your expertise here, I was meaning to ask you And keep in mind my l67 is completly stock untill coupler fix

The exhaust set up i am thinking of is a full redback twin 2.5" exhaust (any brand suggestions) Inc. Y piece to I think the pacies or pacies competion/comp (apparently there is a difference, the exhaust place I went to said it is especially made for l67 or supercharged engines, don't know if he is pulling my leg or not).

what type of tone does the l67 give off compared to a standard ecotec , I had a ecotec 3.8l S and a single 2.5" with pacies and sounded ok a little tingy.

Now do the mods we have discussed rockers, cooler change the tone and flow of air?

Trying to see what first after 10psi, because everyone has said before rockers you will find
more gains in an exhaust, your views?

Cheers,
andy

Hey Andy,

In regards to your questions/statements...

“The exhaust set up i am thinking of is a full redback twin 2.5" exhaust (any brand suggestions) Inc. Y piece to I think the pacies or pacies competion/comp (apparently there is a difference, the exhaust place I went to said it is especially made for l67 or supercharged engines, don't know if he is pulling my leg or not).”

If you can get a orphan HSV setup of a clubsport, GTS of that vintage it would be idea. Real hard to find know missed out on one myself recently Sound the best, work well and are quite. Second to that option would be a redback exhaust system. As for the extrators I wouldn’t worry about these for now unless you get it intercooled. You can get a larger set of pacemaker extrators to suit the VT-VY cars, but not the VN-VS ones. Only Difillipo make a larger set to suit supercharged commodores for in the VN-VS range from my understanding.

“what type of tone does the l67 give off compared to a standard ecotec , I had a ecotec 3.8l S and a single 2.5" with pacies and sounded ok a little tingy.”

The note is similar to that of an ecotec, when it comes to bolt ons, but the induction/supercharger sound is quite different and prominent when they’re spun harder

“Now do the mods we have discussed rockers, cooler change the tone and flow of air?”

They will, but will have more of an impact on the induction sound.

“Trying to see what first after 10psi, because everyone has said before rockers you will find
more gains in an exhaust, your views?”

I would probably lean towards a cat back exhaust in this instance but there really isn’t all that much difference in gains between the two.

Cheers
Steve

Ok mate,

Finally I have some questions furthurmore

Where abouts are you located?

Can I come to you for mechanic work, for example can I get you to install your purchased items for me, for instance I buy a cooler, or rockers are you able to install, as I do not have a lot of time for a DIY project.

I need my coupler fixed before anything, if your able or someone with MACE (a mechanic with experiance as most of you are, if there is more than 1 person), would you be able to help me with that?

Whats the deal with a ported blower, you have on your site to achieve the results, you need a bunch of mods inc. a ported blower, Do youse specialise in this or do I need to see a specialist, whats the price on that?

Do you know any good, trusted, bang for buck exhaust places, last one I went to I was not to impressed, good price though, but left bolts unscrewed, rattled constantly underneath the VT, Poor effort.

Well if you are able to give me a hand with that, wouldn't mind starting of the statesman, I am thinking full mace as I dont like mixing stuff up e.g. FIT, MACE, etc.

My mechanic/panelbeater who is a trusted future father-in-law (to be), is not 100% sure with L67 M90 only serviced one, and mine is the only one he has really worked on fixing up, so needing a little more experiance when coming to modifying it.

Thanks mate
Andy

Spoke to Glenroy exhausts if you have heard of them also

Quoted
$650 for a twin 2.5" straight through mild steel custom made exhaust (he agreed inc. installation)
$750 for pacemakers (I asked for pacemaker comp) - (he agreed inc. installation)
$200 - $300 for 2 hi-flow cats ea

he said about 2,000 with installation.

Is that fair price, I also asked him about the setup you were talking about and he said "He didn't know"

I suspected he didn't really know what was the best setup with constant 10 second silences and pages turning.

By The way, is there a difference with Pacemaker v Hi-tech v Genies, when I have run 3 different exhaust places, they claim they are one is better than each other.

Also I suspect I will be cooling it soon hopefully, I want to make it an easy-painless once off, defillipo are apparently overpriced and you have to go through him. Is there a consequence to getting a certain extractor vs intermediate cooler?

Cheers,
Andy
