How the Magnus Street SMIM Should Be (DEI Reflect-A-Gold wrapped)

[TSiAWD666]

I'm having a 2.3l dropped into my car at Mach V Motorsports. I asked that they take some time to wrap my new Magnus Motorsports Street Intake Manifold with DEI Reflect-a-gold heat reflector material (influenced by Andrew Brilliant aka gixxerdrew).

Evan at Mach V took on the job and even took the thing home with him last night to work on it. He did such an amazing job I thought I should share the work with everyone.

The SMIM wrap turned out fantastic! My only concern is with the manifold severely choking the air volume that the 2.3L needs. Not saying that it is junk; I made 740AWHP with mine at 49psi, but I also made 766AWHP @ 42psi on the manifold I swapped to from this manifold.

If you are running AEM, be ready to have to adjust fueling per cylinder as much as 15% for #1 and #2 cylinders due to the plenum design. I don't know if you have this capability with DSMLink due to my inexperience with it, but it is worth checking with Tom Dorris on DSMLink Forums.

As well, with a 2.3L motor, the 264/272 cams are downright puny and you will see substantial gains going to a 272/272 or 280/280 camshaft combination. Again, it all comes down to power goals and usable powerband. Just wanted to forewarn you of the airflow required to make an efficient setup.

I hope that it works out for you, but just wanted to give you the heads-up before burning a piston/popping a nice new motor.

Good luck,

Wow, I really dig that. Make fun of me if you would like, but gold is my shit. I think it would great black where the wrap is not in place, and have the word "magnus" be black as well...but looks good either way!

Please post pics once it is installed, I want to see it on the car!

That looks very nice! I personally would have gone with silver, but that's just my preference.

No, you can't. You can only adjust deadtime per injector. This would be a nice feature though.

 

[TSiAWD666]

Thanks very much for the advice! Didn't expect it at all when just showing off some "bling". I'm not much of a bling guy but the beauty of how this turned off I had to share.

I might have chosen the wrong smim for maximum power, but wringing every last bit out of this engine isn't in my goals (yet). I'm looking for much better low-end response and in general throttle/boost response than I've had up to now on a stock 2.0l as I enjoy track events and soon time trial events. This is why I chose the smaller intake manifold rather than Magnus' Race or a Venom SMIM... I simply guessed it would give me better response. If I get to the point where I'm comfortable with other changes to the car (it's going through a drastic overhaul right now including Drew's body kit replica) I'll explore looking for more power I'm sure.

I don't know if Dsmlink/Ecmlink supports per cylinder fuel adjustments. I have dsmlink v3 now but only updated to it about two weeks ago and have all of about 10 minutes in the interface as I only transferred old settings to get my car running before giving it over to Mach V. I'll have to look into this!!

Thanks for the cam tips. I know the 264/272 combo isn't appropriate, and so with this 2.3l goes a head with machined by Rich at TEM Machine Shop (as recommended by Drew) including Forced Performance FP4R2 cams.

Looks Great!!

Wow that turned out good, post some pics with it installed.

I honestly didn't chose gold because it was gold. I chose gold because that was the color in which I found the most reflectivity per specs I'd researched. DEI's wrap appeared to my uneducated (yet I do have an EE degree) eyes to have the best specs for the price at 850 deg F direct heat tolerance for like 6 or 8 hours. I didn't run across any silver products at that level in the sub $50 price range for a small sheet.

Oh, I should add I was choosing this originally for wrapping my main water pipe behind the turbo which is why I was trying to get the best specs at a reasonable price. The manifold was a last minute "oh shit I forgot about this..." moment and Mach V just happened to have the same DEI reflect-a-gold product on hand so I went with it. I really don't know how much this helps with intake charge temps and did it because I saw Drew had done it in some engine bay shots. I don't really care what it looks like too much... I'm generally a form follows function kind of person. No one sees my engine bay as I'm racing by them on the track so who cares

Thanks for the info on dsmlink! I won't have to waste time researching. I'll have to keep this in mind for when i move to Motec or AEM down the line.

Here's the specs on what my brother and I just ordered, in case you'd like a silver option at some point. We found this product from EvoM.
Heat Reflective Tape "Gold vs. Silver" - evolutionm.net


Aero-Lite Heat Reflective Tape
$24.85/liner foot (as of 3/11)
15" wide x X' long (order by linear foot)

• silver front
• capton-based material sandwiched between foil and adhesive
• 3M adhesive on back
• 96% of heat reflected, up to 1100°

From Earls Indy.

 

[TSiAWD666]

Well that just goes to show my quick half-assed research could have used a bit more time Appears to have much more reflectivity than DEI for sure. Next time I know what to get!

How do you go about knowing cylinders #1 and #2 needed 15% more fuel?
Individual EGT Probes?
Reading Plugs?
Individual O2 Sensors?
Or just being a bad ass?

I think silver looks better just my opionon but a nice piece there

 

[TSiAWD666]

Heh I should add that after showing these pics to Drew he responded with something to the effect of "I am using this other better stuff", mentioning a place he works with. Looked at that place's website, and sure enough it's the same stuff from Earl's Indy. I should've just asked Drew in the first place what to get but thought this would be one thing I'd figure out on my own

 

[snowborder714]

What place did he show you that he got it from?

 

[TSiAWD666]

Coast Fabrication - Heat Reflective Tape NEW!

He's actually switched to the silver too.

Look's good imo.

Chris, our conclusions regarding the fueling differences came from a few things including a lot of dyno time with individual egt's, infrared temp logging per runner, logging individual duty cycles, reading plugs, etc. Along with trying out different designs for manifolds when we were prototyping the Beyond Redline SMIM. When we finally got to a finished product that was a larger volume surge tank with more "equal" flow to each cylinder, we had to do a lot of adjustments to the tune as it went richer nearly 2 full points AFR on the same tune with just a manifold swap. After all the adjustments were done, these were some of the conclusions we had come to. We also changed from 272/272 to higher lift 294 custom cams with fresh valve springs and gained another 20-40whp in the mid to top end. This was done on the GT4088R setup in 2007.

Here it is installed on the new engine.

This is exactly how I had calculated the #1 vs #4 airflow differential being for that manifold. After having #4 on my oem engine bend a rod on a 16g, I will never advise anyone in running a magnus. Yes, they're better than OEM, but no, they are by far not the best. 15% leaner in #4 vs #1.

 

[TJCTalon]

^ If you dont mind me asking, what manifold do you advise to run then?

It seems everyone runs the magnus. Whats the better mani to run?

I run the JMF "Race" and the #4 cylinder is the first to detonate in my car, but i don't know how much leaner that cylinder is, so i can't tell you how many % it's off by. I've never logged AFR per cylinder because with link there's no way to adjust the fuel delivery, so it's not very useful info.

 

[TJCTalon]

So its the same with the JMF?

To me, our engines are screwed in that sense. No matter what manifold you run, #4 will get less air then the rest. But I guess its the manifold that can reduce said percentage the best. This would be an awesome discussion.

 

[BigBeans]

So its the same with the JMF?

It's off a bit, but i can't say how much. Maybe there's someone who can provide that info for you?

Whether it's better or worse than the Magnus, i have no idea.

BTW, number 4 being leaner means it gets more air.

I like several manifolds for the DSM with a 1G head flange. I am running the Beyond Redline Performance SMIM (here is a link of it tested on my car vs. Magnus SMIM: http://www.dsmtuners.com/forums/bol...-performance-sheet-metal-intake-manifold.html) I also like the new Magnus cast intake manifold that was just discussed, tested and produced great numbers. As well, the JMFab Drag manifold, the AMS VSR intake manifold, and the Forrester cast intake manifold are all great proven manifolds. All of these manifolds should do good on a high-revving 2.0L or big airflow larger displacement 4G63 variant/stroker.

 

[Boosted98gsx]

I run (since i helped design it) the DVDT fab manifold. But it's not a cheap mass produced manifold like the JMFAB / Magnus manifolds.
