MACE's Intake Insulator/High Flow's Ported Intake Manifold

[TJ91]

insert elevator music here


Im too excited

[bmorecam]

Well, it was a looong night, somewhatbut got some numbers for you guys. Before I start, I think mace's graph is from another world lol. As you guys are about to see the torque does not have over 10% spike in the lower rpm or anything that look close to the gain that we seen on mace's advertised graph.

Anyhow, today's gain.. "peak", 9hp and 13lb ft of tq..I guess ok, and the good part, "off peak" almost all across the range, 20lb of ft tq and 18hp Not bad. Today's AFR averaged around 11.6-11.7, still a little rich from the usual 12.5+. Just got home and checked the mailbox and had an update waiting for me from vince

Today's dyno condition(nov 14th) 71F, 41%, 29.82 Pressure(274rwhp, 259rwtq)
(baseline)Last dyno condition(oct 11th) 69F, 79%, 30.07 Pressure(265rwhp, 246rwtq)

As you can see the condition was almost identical for both of the time.





Do you guys remember the e85 dyno? check the comparison. The same 20ft lb of tq gain over e85.

Nice!

[BloodUSMC]

VIDEO?

JK LOL GREAT JOB JAY

[bmorecam]

here is the video from the last run if that get the spirit up a little lol

[TJ91]

Thats pretty awesome man, is that without the tune?

[OOLIE]

The low end increases are pretty impressive. 20lb torque definately will be felt in the butt dyno. Nice Job Bmore.

Supposed to get her back tomorrow.

[bossbunny]

Very nice!! Still not bad!

[TJ91]

i cant wait to see what the tune does in terms of feel

Looking good Bmore!

I may have to save up and order this Intake Insulator and get my intake manifold ported.

Do you think that the height of the insulator will make a big difference in the overall gains or should we expect respectable gains regardless of going with either the 6mm or 12mm insulators?

[bmorecam]

Vince doesn't think there's nothing else to tune except to correct the AFR which normally will add a few horses but nothing big. I do have something in mind tho that I think will work pretty well but I have to talk to my porting guy darin D. about it later.

As far as the insulators.. Hmmm.. I'm not as optimistic about it as I was before after looking at the graph carefully and comparing with my torque graph and mace's. I think the gain is there but not as much as I thought. There's just absolutely no footprint from the original mace's dyno graph to mine so I don't know what to think of it as of yet. It's not even close. I basically gained throughout the whole tq band where as mace's has a big spike from about 30mph to 40mph. I think at this point I am leaning more towards the porting work as the suspect for most of the gain.

but we will find out more and I will keep you guys updated as I move on

Interesting stuff. Now you need to get that terrible ledge out of each head port. A gasket match is in order. There's no doubt that this is hurting power. I've seen it before.

That's what I was thinking too. I think I am definitely leaving power behind due to turbulence going in the head. I don't understand why mace matched their insulators to the gasket which made my day worst

Darin, check your email and let me know what you think bro.

yeah that didnt make too much sense.
I wonder what this combined with E85 would feel like

Good to see that you've finally run the car up Jay

Going by the results you've achieved with this setup you've snared over an 8% gain in torque, so we weren't too far off I guess

The graph that we have on our dated add is only of a LY7 engine, which has considerably shorter runners, along with the seperate L36 insulator ad we have.

Regardless though, I'm comfortable to refund anyone's $$$ if they're genuinely not happy with performance of the product.

In regards to the product dimension specifications, arising in potential mismatching, practically speaking it's unavoidable. Primarily because of the manufacturing process of the cylinder head and inlet manifold which are sand cast.

Sand casting, though great for replicating complex geometrical shapes, has it's pitfalls in that it's manufacturing tolerance is usually +-.040" if not more depending on the quality of the patterns sand etc.

Given the shear number of cylinder heads and manifolds made, it's not practical to be able to offer an insulator that matches perfectly to every single LLT engine made. In saying this though, we're open to any design revisions as additional information presents itself

If we were talking about an LFX engine, with it's injection molded plastic inlet manifold they we would be a lot closer, though the head would still unavoidably vary dimensionally :(

Fortunately though, given the Reynolds number, its not a huge issue. Sure it will cost hp, how much though? Likely to the tune of a few hp if that. Don't get me wrong match porting is ideal, however they will genuinely still work quite well out of the box.

In saying this though, these are still a relatively new engine, with testing such as what you've conducted a great thing for the LLT community

In regards to insulator and other components for these engines, it's something that is on going. I can't stress this enough!

Kindest Regards,
Steve

Thanks for psoting up Steve, glad to see you have joined up and are putting some good work into our LLT engine. Can't wait to hear more about this subject and the intake manifolds.

Hey steve, thanks for coming by. I know you guys are probably very busy having to deal with the commodores and now the LLT and with future products.

I know the LLT guys will be more than happy with what you are bringing to the table all the way from the other side of the world.

Indeed, was it the porting or was it the Mace? Therein lies the rub.

The Mace, even in a sub-optimal level of design, would be a Big bang for the buck if it could take credit for all the gains.

MACE_ENG I would suggest to you it would be to your very great financial benefit to repeat your testing with the LLT in U.S. trim (2010-11 models would be my preference of course).

And Bmore, we sure appreciate you , and are glad we all share the enthusiasm for this car.

So...can you dyno it one more time with just the mace???

I am about to modify the insulator to suit my need so I might be able to do it the other way around.

But I won't promise anything. It all depends if I have the time to do this. Dyno is really not an issue as I have access to SRT as I need from now.

But we will see

[Ventmaster]

Fair enough! I think High Flow and Mace should be compensating your for your time.
You're doing more than anyone else already- sorry if I was being out of line!

They been good to me no doubt!

[SC2150]

I like it! Good work, and well worth the $$ for the gains.

[usa1camaro1969]

What if, rather than it being opened up too much, it was actually a little closed up, so we could port match our own isolator to our own individual heads?
