C6 Corvette ZR1 & Z06General info about GM’s Corvette Supercar, LS9 Corvette Technical Info, Performance Upgrades, Suspension Setup for Street or Track
Just picked up my vette Friday from East Coast Supercharging and I could not be happier with the build. I previously had most of the bolt ons, CAI, kooks catless 3" headers, kooks straight piped into a corsa sport exhaust. With that setup at ECS, I had it dyno'd at 468 at the wheels. My goal was to break 600whp and thanks to Tony Mamo I did, 608whp. On this build I added the following:
LME Ported LS7 heads
Katech LS7 Torquer 110 Cam
MSD Atomic Air Force LS7 intake ported by Tony Mamo
Nick Williams 103mm throttle body ported by Tony Mamo
I did a lot of research on this build and I can tell you that without Tony's porting skills I would have gotten around 578whp, so his skill definitely, in my opinion, put me over the top. The Katech 110 is a pretty mild cam, so I'm guessing I got 25whp from the porting alone. We did run into a hickup, which I'll add here for others. After all the car was assembled and Doug at ECS had her on the dyno, she would shut down at WOT with reduced power and code p1516. ECS thought it might be a faulty tb and both Tony and Nick Williams were eager and quick to help. Nick sent me a screenshot of the dyno setting to give to ECS and after that, everything was golden.
The car sounds awesome, has great power and is still supposed to be driveable as a daily, although I won't find out until spring.
Thank you ECS, Tony Mamo and Nick Williams. I can't wait for spring!
Thanks for posting your results. I will end up with nearly the same set up. I am at 555rwhp and still have the intake, tb and I am doing e85. $1795+shipping seems like a lot for an intake but the results seem impressive.

Most of my MSD customers pick up on average 35 RWHP from my ported MSD intake manifolds.
Better heads and more aggressive combinations can see 45 RWHP gains......for $1795 thats a damn bargain and it represents very cheap power (even a milder combo that sees 35 at the wheels.....under 2K for this type of gain is a homerun)
Understand that these intakes sell for $1200 now out of the box and my porting work almost doubles the gains from the install
Here is a recent result one of my customers just shared with me.....this is an unported MSD on an unconventional small bore 414 LS7 combo (4.060 bore engine) with 10 year old lightly ported OEM castings so not an ideal engine combination to maximize gains from a ported intake
The dyno comparison featured below is the same exact 414 CID combo with an un-ported MSD versus a ported MSD I recently sent him.....no other changes except the porting work.
Note a typical large bore 427 engine with better heads and a more aggressive combination typically sees a little more and keep in mind this is 3rd party independent test results.
The better the heads and the overall combo the larger the gains from the higher flowing ported intake as the stock unported manifold represents more of a restriction in a deeper breathing combo with better heads and larger camshafts.
Best thing about the gains you see below is power and torque are picked up across the board adding nicely to the average power output of the engine as well as improving your time slip
Once again so Im clear.....the gains seen below are JUST FROM MY PORTING WORK....the baseline had an out of the box MSD intake and 13 days later the customer installed my ported MSD intake.
SAME combination on the same dyno both with an optimized calibration from the same tuner....ideal testing parameters.
GAINS FROM PORTING ONLY
Are those gains featured in this independent test worth the difference between a $1200 out of the box intake and a $1795 ported intake?!
You bet it is.....it's worth every penny. My customer was thrilled with the results as he was hoping to get alot closer to 600 RWHP with the porting work
Someone just posted..or it may have been one of the hundred old threads Google brought up. Think it's recent, anyways, the gentleman had Tony port his intake over the Holiday break and hut the dyno. He gained 14whp and around 9-10 lb ft of torque. Really impressive! It would have been nice to see what yours dynoed before. As no 2 engines are the exact same.
Sounds awesome! How was your experience with the shop? I'm located in north Nj and looking for a reputable shop to swap out my harmonic balancer
ECS is awesome in my opinion. If you read through these forums, which is how I learned about them, you'll see they have a stellar reputation. Not just in NJ, but from all over. They may not be the cheapest in your area, but I'll spend a bit more to know it's done correctly rather than spend a lot more later.

I also would have loved to do a before and after, but at $700 for a dyno run, I wasn't that curious haha. Also the engine was apart for heads so they would have had to assemble it and install the old tb and at then swap to the new. Lots of work. I know Tony has a bunch of before and after tunes he' done, which is one of the reasons he sold me on his skills.

Oh yeah, there's a ton of guys porting , but Tony is the man on these intakes...based off what i see and read. I honestly wonder why more dont use his heads. Hes suppposed to do some magic with cyclinder heads as well, uess it boils down to cost.
I ran the first generation Katech 110 as my first engine setup and loved the torque numbers it made
It ran out of steam after 6300 and I was running the dragstrip with it as well, but it still went a 10.4@133 .
I had a Fast 102 and NW102 on 1/7/8th headers and it made 575/555 SAE, so your numbers sound right on target.
Do you track your car? Did you consider a supercharger from them? I’m on the fence as to how I want to build my Z.
I don't track it. I was back and forth for 2 years about boost vs NA. I had quotes from ECS for both. In the end I wanted to stay NA because of the sound and the boost limitations of the 427.
I went the HCI route a few years ago and have almost identical HP and TQ numbers. 606 RWHP and 558 RWTQ. Only part that is the same is the Intake ported by Tony.
Looks like you have more TQ under the curve and I hit peak HP a little later in the RPM band.
Man, this doesn't help me at all. I pretty much talked myself out of adding an ECS system and to just stick with the heads/cam setup that I have. Now im wondering if I could get away with it. I hate this forum sometimes.
