[Tony @ Mamo Motorsports]

Guys,

Haven't posted on here in a long time....been busy with so many different projects related to my business (I handle just about all of the GM platforms including old school muscle as well).

Anyway.....been working on this new TB for quite some time. The main difference between this and my v2 unit is a little more airflow (about 20 CFM) and the fact this is fully CNC ported. We invested a ton of time come up with a really effective good looking part with what could pass as an OEM machined finish in most cases. Besides the substantial gains in peak flow (over 200 CFM!!) there are nice gains across the entire curve as well (basically gains in part throttle operation).

Bottom line....if your still running an OEM LT1 or LT4 TB on your car you owe it to yourself to try this upgrade. It will transform the car. The factory LT throttle bodies are the worst GM design TB's ever installed on our favorite GM rides.....I cant believe they also installed them on the C8 platform as well including the new C8Z06. (I guess from the standpoint of potential sales I should be happy but shame on GM for doing so)

I posted some pics of the product below....it offers a substantial 23% increase in flow over stock and a similar gain in airspeed as well (that's the winning formula right there).

What are the bullet point gains....what can you expect from this upgrade!?

In no particular order I would list the following

Eliminate the dreaded off idle and low speed dead spot inherent in the flawed design of the OEM TB (huge perk there)
MUCH more throttle response from idle to WOT
Improved tip in throttle (when you roll into the throttle without downshifting)
Smoother more intuitive feel to the throttle....you will have to drive it to understand
Makes the car feel 300 lbs lighter....snappy and much more lively driving experience
Significant gains in peak power....excellent value in HP per dollar. LT1/LT2 cars see 8 - 10 RWHP......LT4 cars (boosted) see about 15 RWHP

Your biggest complaint will be that you didnt do it sooner. Seriously if any of you reading this are still running the OEM TB, reach out to me. Im so confident about this new product (and trying to get the word out) that Im even willing to offer a 30 day 100% money back guarantee including covering all the freight cost as well if your not absolutely thrilled with the purchase....at least till I mention otherwise. Now you have zero excuses for not ordering and trying one.

Also it's a 10 min install....remove the clamp from your CAI, disconnect the electrical connector plug to the TB and its four 10mm bolts away. It's a piece of cake.....even guys that don't normally do their own wrenching can tackle this quick project.

$459 plus $23 in freight /insurance....Sales tax only collected if you live in California.

This is the best sub $500 mod you will ever install on an LT powered vehicle mainly because thie upgrade is more of a fix to a really poor OEM heavily flawed design.....that's why the gains are so significant here. Ask any of the guys already running my V2 or just take the time to search.

I have a few in stock at the moment....have more in the pipeline. If you go on my website now and order the correct LT1 or LT4 you WILL receive a new CNC ported V3 TB in the mail....I am no longer building any of the V2's....this supersedes that product.

See pics attached....just cell phone pics but you get the idea. This is a high quality part that runs as good as it looks.

Feel free to PM, email or call if you have any questions (I prefer email and phone over PM's.....you will get a faster response from me if you email or call me)

Look forward to all your feedback as well

Cheers,
Tony

PS.....I SHOULD HAVE MENTIONED GUYS THIS IS A PLUG AND PLAY MOD.....NO TUNE REQUIRED

ALSO....IN THIS 2nd PIC BELOW WITH THE BLADE OPEN THAT VERTICAL LINE YOU SEE IS A RAZOR BLADE THAT IS HOLDING THE BLADE OPEN SO I CAN GRAB THE PHOTO TO COMPARE STOCK VS PORTED !!!!




STOCK TB AT WOT





PORTED TB AT WOT.....THE DIFFERENCE IN CROSS SECTIONAL AREA IS HUGE. THATS WHERE THE 23% ADDITIONAL FLOW COMES FROM

can you provide pre/post dyno video or charts for the lt4 (no tune)?
thx!

Honestly there are dozens of dyno comparisons, videos, and feedback out there from my V2 product. The V3 will only be marginally better but my point is whatever positive feedback you find on my V2 product certainly applies to the slightly better flowing V3 product.

That said, of all the independent feedback I have probably received since launching the V2, the one I copy and paste below (from the Corvette forum) is probably the most informative covering anything and everything someone considering this upgrade might be looking for.

Also, on a boosted LT4 application you will actually see more boost pressure as the blower is able to capture more air and then compress and force it into the engine. The is also mentioned and discussed in this post below as well

Did I mention the 30 day no questions asked warranty??.....LOL

I have been in this industry for over 3 decades and have an excellent reputation....just buy and try one. Your biggest regret will be that you didnt do it sooner

Enjoy this information below....this customer spent alot of time gathering it all and putting it in a reasonably easy to understand super informative post

Cheers,
Tony

As there are always doubters, which there should be, I will disclose as much information as possible. First, I purchased my Throttle Body for full price. No discount, no favors. Second, I was not paid to do this. It is pretty boring during lock down as we all know and I do this stuff as a hobby so I enjoy it and no one has provided any data like this that I have ever found. Third, I data logged all of the dyno pulls and just like my thread over in the Z06 section, the airmass changes did result in power changes. My method of testing here was to be as transparent as possible. I drove the car to the shop, pulled in on the rollers and let it cool off for about 45 minutes. Made two pulls back to back and was going to make a third but since both pulls were nearly identical I chose the best one to be the comparison. I then swapped on the Tony Mamo version 2 throttle body while the car was strapped to the dyno and then let the car cool off for 45 minutes. I got the car back up to temp and made a pull. I then made a subsequent pull with the nearly identical power as the first pull with the Mamo v2. There was no reason to make a third pull just like with the OEM TB.

I also wanted to give a positive word for the guys over at AMP (American Muscle Performance). They were a great bunch to work with on the Dyno. They were interested in what I was testing and were very accommodating to my requirements on how things were done on the dyno. They do all American cars but specialize in Dodge setups. There were some mean sounding Hellcats when I was there. It was a great experience. My next mod I will be right back on their dyno and if I don't want to install the parts myself I would easily let them do the work. Solid group of guys over there.

My car was tuned by me prior to the Mamo v2. The dyno charts below has the first pull made with the OEM TB then the first pull made with the Mamo v2 TB. NO TUNING CHANGES. This was done on a Mustang Dyno and the tech added "Estimated Dyno Jet HP" just so there was that option as well. I'm not concerned about the actual number other than the difference between the two. And I was quite surprised. Even the guys operating the dyno were impressed. One thing to note is since the Airmass went up with the Mamo v2, the ECU was referencing a higher part of the spark table which caused timing to be about 1/2 a degree lower with the Mamo TB. You can see the difference in the last two screenshots of the Datalog. If I would have re-tuned to bring the timing back up I probably would have picked up another 5rwhp.

Dotted Line: OEM TB
Solid Line: Mamo v2 TB
Notes: The dyno operator used my gear ratio of 3.42 and we ran everything in 4th gear which is 1:1. They did not use an induction pickup to monitor the tach signal. The Dyno charts RPMs seem to be slightly off which I assume is because they didn't have the tire height exactly right. This likely threw the RPM calculations off on the chart, but all pulls were from 3000-6600 RPM as you can see in my data logs.





As mentioned I also data logged the runs so that the information that I posted in the thread below could be confirmed. The data logs in this older thread actually show better peak boost numbers but that is to be expected when comparing to dyno pulls. But as you can see below the datalog comparison focusing on Airflow/Airmass/MAP/Pressure.
https://www.corvetteforum.com/forums...xperience.html






Now here you can compare datalogs. Here are a few things to notice.
#1) As you can see above, the airmass with the Mamo v2 is higher, meaning more air is moving through the engine. This causes the spark lookup table to move to the next higher cell which is half a degree lower to account for the extra boost. So the Mamo v2 pulls actually had 1/2 a degree less timing vs the OEM TB pulls
#2) No Knock Retard on either pull
#3) Long Term Fuel Trims were identical. When referencing on the dyno computer there was a .1 difference. The dyno chart even shows that(12.0 to 12.1 average). As expected the MAF added more fuel because it saw more airflow, but the AFR being .1 leaner means the car was using the extra fuel to make power. The dyno chart proves this.

Mamo V2 Dyno Pull Log





In summary, I leave this for each to develop their own conclusion. I am very happy and the money is well spent. Car drives great and Tony is a great guy to do business with.

Enjoy...

Thanks Tony, I was really looking for a before/after comparison on stock setup with no tune, but this is interesting none the less.

What you should be focused on is that with no tune, the computer compensated for the extra airflow the TB provided by adding fuel and providing a bunch more power with no changes to the tune itself.

The fact it was tuned previously only means the baseline power of the car was a little higher. What's more important is the gains from the additional airflow provided by the TB netted significantly more power at the rear wheels without plugging a laptop in and adjusting any of the tune parameters. The ECM took care of all of it due to the MAF registering the added airflow

A car with an OEM tune will respond exactly the same....the additional airflow will net you more power providing you with similar gains/results (most guys in stock trim have seen 12 - 15 RWHP on LT4 combinations....if you Google it's out there)

All that said , the reason to buy this product is NOT the gains in peak power as I have said previously many times....it's the massive improvement in part throttle operation, overall response and smoothness of the throttle.....you experience and appreciate these gains every minute your driving the car not going WOT (99% of your driving). The bump in peak power and performance is nice and certainly welcomed but the enjoyment in the day to day driving that you constantly experience at ALL part throttle operation is the real reason to own this mod. Completely eliminates the dead spot just off idle.....if your not familiar with what Im talking about focus on the throttle more the next time you drive the car. Once you install this mod you will really understand and appreciate what you were missing all this time

I just recently bought the Tony Mamo TB Thursday, got it and installed it today. I will say it is definitely a game changer for a stock tuned manual transmission car.

Mods: MPI Supercharger Lid, Corsa Catback (Still have all stock cats), Tony Mamo TB.

Wasn’t trying to push the limits of the stock tune so I am going one step at a time with mods and see what reacts the best. I went too fast with my C7 Z06 so it feels really good to start over with my Camaro.

The difference with Mamo TB: Supercharger whine was already louder with the MPI lid, but now it is more so as when stepping on the throttle, the car goes up in RPM’s much more smoothly and faster. Also, gas has been a huge factor with this car. I am on the west coast with 91 only (car is super sluggish, also Gas Range only goes to 267 on a full tank) and have to find gas stations with race gas to mix 91 with either 101 or 100 octane and the car stops being sluggish (94-95 octane and the Gas Range goes to 369). The only thing that would remain from time to time is the dead spot when letting off the clutch and hitting the gas. With the Mamo TB, that dead spot is completely gone. The car definitely feels how it should have felt from factory. So far it is definitely worth the purchase, I will keep driving it and will end up doing a journal of all my mods. Did not do a relearn procedure or anything like that after install of the Mamo TB.

Really appreciate the feedback....this is how the car should have driven right off the showroom floor if it had a properly designed throttle body.

As I have mentioned this mod is more of a fix than an upgrade. The GM OEM TB shape is so bad it creates alot of issues in performance and drivability.

Did you take a good look at the OEM shape versus what I sent you? I swear pictures just don't convey the difference and how poor the OEM design is. Im absolutely baffled why the worst TB design GM ever came up with has had the greatest cycle life of any TB they have ever released...and its still going strong 12 years later with the 2026 cars (first one was released on the 2014 C7).

LS1 TB ran for 7 years (97 - 2004).....LS2/LS7 silver blade 90mm from 05' to 08'.....the LS3/LS7 90mm bronze blade unit (that was actually decent out of the box) from 09' - 15' ....and this design ever since.

I would have bet my life savings they were going to scrap it for the all new C8 but they did not!

Catch you guys later

Yeah I definitely noticed the difference and pictures really don’t do it justice.

I ordered from your website at the time it said V2, I have been trying to find pictures or see the difference between the V2 and the V3. Is it mainly the V3 is more smooth? Also what I found only is that the V2 blade looks to have black shadow in the etching of the Mamo LT4 lettering and the V3 doesn’t? (Could just be how the pictures were taken) but how do you tell the difference between the two?

Thank you for making this amazing product.

[hawk02]

You make no mention here or on your website if the LT4 v3 TB is compatible with the gen3 Cadillac CTS-V or the CT5-V Blackwing.

The V2 is hand finished....its all ported and shaped by hand.....it will have a sandroll finish. The V3 is CNC ported and will have a machined finish. Slightly different housing bore shape....slightly more flow. If you have a V2 its not worth the swap unless you just like the aesthetics of the V3 machined finish.....the performance gains are very negligible between my V2 and my V3.

If you have a stock TB....one of my V1 units or any ported TB from a competitor, I would say you will notice a solid improvement from purchasing and installing my V3. I welcome that challenge actually

Don't forget I offer the 30 day grace period....don't feel it was worth every dollar you spent send it back for a refund but Im confident you will like it

I offer these for the V3 CTSV's / Blackwings etc.

Reach out to me directly with that car. The ECM is super fussy and I have to send you a specific ported TB for that application

Hit me via phone or email (those contact methods preferred over PM's)

Ok thank you for the explanation. One last thing I have heard is that eventually the car will relearn due to the stock tune and end up driving like stock again. Have you seen instances of this happening?

[ZLRob]

Are these going to be like the Soler throttle bodies where they claim that you don't need to do any tuning to it, but in reality you need to wind up messing with the virtual torque to get it right?

[Megahurtz]

I can confirm no tuning is needed for Tony's ported V1/V2/V3 OEM throttle body.
