Tony Mamo Ported Throttle Body Installed

dmwtech · 01-08-2018, 09:30 PM

I ordered a Tony Mamo ported throttle body a couple of days ago to install on my new to me 2017 ZL1 with 10.5k miles. Ordering was a piece of cake. Sent him a PM on here, he gave me the price and a link, I paid and he shipped. Tony over delivered and got it to me on the day he said he'd actually ship it. Sneaky guy!

Tony asked me if I wouldn't mind trying the throttle body before installing the Roto-Fab CAI, so I'm going to drive the car around for a week or so to compare stock, to ported throttle body and then to ported throttle body + CAI.

Installing it is very easy. I timed it and even while taking a number of pictures, it took me 13 minutes to install and you can't get much easier. 15 minutes would include getting the tools out and putting them away. I did use my Milwaukee cordless 1/4 ratchet to speed things along though. Don't have one? Buy one and thank me later.

After:

I'll post up my thoughts after putting a hundred or so miles on the car. Just waiting for the rain to let up here in Cali. The car fired right up and idled like stock. Revved it up a bit and got sad because it's raining! LOL

Here's what I'd say about my experience with Mamo Motorsports:

1. Extremely responsive. I mean, EXTREMELY.
2. Friendly and informative.
3. Stands behind their product.
4. Shipped days ahead of schedule to over-deliver to their customer with excellent packaging.
5. Quality workmanship. The throttle body was ported very nicely.

Tony charges a bit more than some competitors, but like I told him, I knew who was going to get my money. I have no doubts that I'll be pleased with the results, but the verdict is not yet in. More to come......

Installed mine about a month ago. Very pleased with the throttle response.

Tony was great and I'm thrilled with mine.

Yes. Nice write up and photos. Do you have other photos showing the actual porting (I don't see it in the side by side)?

If you look at the fifth photo, you can see a decent sized ridge on the left (stock) throttle body. Unfortunately the lighting wasn't the best when I was taking pictures, but there are some other threads on here which show the differences. In the stock throttle body, it has a ridge/lip on the top and bottom. Tony removes this to increase airflow. I believe it was north of 150 CFM more on the flow bench. It also reduces turbulence going into the intake.

The easiest way to see it is to remove your stock rubber throttle elbow. Run your finger inside of the throttle body and you'll feel the ridge/lip. In Tony's ported version, that is all smooth with a very nice transition.

I took the pictures not so much as a DIY since several of those exist online. Check out this video which gives a nice outline of the TM throttle body:

Tony said he would ship mine yesterday, but it was waiting for me at the house when I got home today.

Thank you.

From the photos, it doesn't look like the blade sits flush anymore.

I've never had experienced with a ported TB, but can't this negatively effect A/F?

speedraider · 01-10-2018, 11:38 AM

What are the positive effects with an A10. We all know the manual stumbles off the line.

I was thinking the same, until I saw the stock TB had the same , Plus, check out the bottom of the butterfly on the stock one, big gap too

Yes, there's a gap there too. It seems slightly bigger on the modded one. I would think that would result in a rough idle if so.

Gutling · 01-10-2018, 11:54 AM

It looks like the butterfly is actually tilted a bit in the pictures, maybe why the gap looks so big. Maybe not closed all the way?

The car needs air, even at idle..
