Hello,

Finally got my Mamo heads, cam installed on my 2007 Zo6. Results were quite amazing in my opinion.

First of all dealing with Tony was very easy, he is very helpful, easy to talk to and responds very quickly. Highly recommend working with him.

Back ground... dyno before new mods. Mamo ported MSD, NW102, LG 1 3/4 headers with cats and xpipe, factory 2012 rear exhaust, Vararam intake. This setup dynoed 534 HP and 495 lb/ft standard correction. The ported MSD picked up almost 40hp over the previous dyno.

Now the Mamo heads(11.8 to 1) and his valve train, cam(238/251/114) and ATI pulley, everything else the same as above. This blew me away... 644 HP and 534 lb/ft std correction.. SAE was about 632 hp. All this on a very conservative tune(going back this coming Tuesday to work on it). Air fuel set at 12.35 and timing 26 in the upper end. I'm sure there is another 10hp in the current tune. Need to work on the surging down low, but I'm sure it will get there as its currently smooth above 1600 rpm, but needs some work below that and when off the throttle.

Needless to say I was very happy. I dynoed on two separate dynos and set records for modified LS7's(N/A) on their dynos... both shops were quite shocked at the power it made.

Anyway, thought I would share...as this combo makes tons of power and gets rid of the worry of dropping a valve.

Thanks Tony for your amazing product, under promising and over delivering.

Cheers,

Alex

Tony is the man! easy to work with and has a great product.

Tony is great to work with. I've been fortunate to live near Tony's shop (200 miles) and I picked my heads up from him. The shop that he is in the process of build will be amazing. 07, great combo

Jayfabs

That's awesome! Was this with 93 octane? Any dyno graph? I have the same setup but still a month out from dyno. Tony is a super great guy to work with!

07raw

Tuned for 94 octane. I just have a picture of the graph.. I'll see if I can figure out how to post.

Congrats, Thats great power!

Was the old dyno number with factory heads and stock cam?

Public Enemy

Wow that's really good for 1 3/4 headers.. I think if you put some 2 inch headers should add another 15hp to your combo

534rwhp with stock heads and cam?

40rwhp gain from a ported intake?

07raw

Yes... headers, vararam and tune was 498 hp or so... Mamo ported MSD brought that to 534 standard... That manifold and his port work are some of the best gains/dollar out there!

07raw

Yep... that's what I've been told... will most likely do, not sure when though.

07raw

Factory cam, heads had valves and guides replaced to avoid dropping valve... so a little would of been shaved off to cleanup the heads(minimal).

yes, so HUGE gains with his cam and heads over stock cam and heads.

damn these mamo packages are awesome

Those numbers are very hard to believe... What kind of dyno? Surely i'm not the only one who would like to know. Do you have a dyno sheet from each round of mods?
Pretty incredible numbers...

nuke61

Awesome result, the 94 octane looks like it helps quite a bit. Wish we could get that here - 91 octane at the pump.

I made 539 it factory heads and cam so very close to the op.... I'd say his numbers are legit too many peope mod their cars incorrectly and get poor results. Props to the op before and after

Tony @ Mamo Motorsports

Alex....thanks very much for taking the time to post and share your results. I've been slammed the last week and this is the first I am even seeing this thread!

Regarding the numbers, assuming they are all off the SAME dyno they are very legit (and I don't know for a fact if that's the case....Alex can confirm or deny).

I say everything is legit if you look at the progression of the build starting with the baseline numbers he discusses which most would agree are very much inline.

Looks like he started at 498 STD corrected with the mods he had at the time (headers, tune, CAI, etc.)...those numbers certainly make sense and if anything are a touch low factoring in they are STD correction factor which reads approximately 4% higher than the SAE correction most use to post chassis dyno results.

Looks like he added my ported MSD after that which picked up almost 40 RWHP (I have seen that type of gain with my ported MSD alot more than once btw). That puts him at 540 STD correction (520 ish SAE....very much inline) and then he installs my MMS 265 heads, medium sized cam and my valvetrain gear and basically picked up another 100 and some small change landing at 644 STD.....which is closer to 620 SAE and that makes alot of sense to me based on all the other combo's I have built and spec'ed. Not to mention if all of this was on the same dyno its hard to argue the results! Larger headers would add a minimum of 10 RWHP

Alex....can you confirm that this was all the same dyno and also confirm the final SAE numbers....644 on the STD correction factor should be closer to 620 SAE, not 630....want everyone to have the correct information. Either way the numbers are extremely impressive for a modest cam and 1.75 headers even at 620 SAE.

Guys I have worked long and hard on my LS7 gear and Im a huge fan of this platform....in fact I work on a lot of different stuff....have some killer BBC parts....awesome 23' Gen 1 offerings, some killer inline Ford products (blasphemy I know!), but the LS7 is my personal favorite and I have devoted a large portion of the last three years dedicated to this platform (since leaving AFR in 2014)....working on my LS7 program is really where I have dedicated the bulk of my R&D time.

So as you can see Im very passionate about this product and the results you guys are seeing didnt happen by accident....alot of time has been dedicated to the development of the entire combination (not just the heads) that I am helping you guys with.....for you guys sitting on the fence reading I suggest you take advantage of this. I have driven a few of my customer's cars with my complete packages installed and they are nothing short of thrilling to drive....explosive everywhere....even the bigger cammed stuff just gets up and goes regardless of RPM....its not lazy at any RPM. The smaller more efficient port designs in my new heads promoting high air speed and high airflow (the winning combination) which is what really makes all this a reality.

More results are coming....I have another dozen of so packages in the works right now I am completing for forum members that Im sure a handful of them will post their final results as well.

Long live the LS7....simply the baddest production car SBC on the planet....nothing else comes close IMO with the exception of the new Hemi. Guys with my NA packages in C6Z's are walking past boosted C7Z's at the tracks....even modded C7's....its not even a contest.



Cheers,
Tony

PS....Here is a short video (poor quality but the audio track says it all) of me driving one of my customers cars that made 640+ RWHP with my MMS 265 complete LS7 package. It was a steering wheel mounted go pro (hence the turning landscape as I make a right turn on a road I probably shouldn't have went this fast on), and you need to excuse the vibrations etc from the camera mount....but focus on how this car just explodes in first and rips thru the gears. This is the stock tall gearing also but you would think otherwise by how fast we get into 4th. Also this car hooked like glue on the 17" ET Street radials even in first gear....was pinned to the seat as a I mashed it from a 3500 RPM roll....enjoy!

mirage2991

do you do anything for the LS9?

Tony @ Mamo Motorsports

My second favorite platform....LOL (Funny thing is I'm actually serious)

I own a 2nd Gen CTSV that I modded and I sell a ton of my ported TFS castings to the LSA/LS9 crowd. Check out the feedback of my stuff on the CTSV owners forum....have helped dozens of guys there as well as a handful of ZR1 owners as well.

My MMS 260 LS3 head is what you would want on that engine combination....an LS3 head that flows almost 400 CFM thru a port the same size as a stock LS3 head that flows 320 CFM. Email me and we can discuss in more detail....leave your phone number in case Im typed out and just decide to call instead!

Pic of my V in front of my shop...invested alot of time building this car

Tony

Christ that Ls7 is pulling hard! nice work

Ill personally vouch for that V of his, crazy fast true wolf in sheeps clothing.
