General rule of thumb. Port Flow in CFM x 2.1 is the max power the port will support. So if the mamo intake is supporting 800 HP, it would have to flow 380 through each runner. but since you never really max it out, it has to be higher than that. Only way you'll max it out is if the engine is far larger than the induction system.
Maybe at 400cfm?

What is the maximum power that the LSXHR can support? Does anyone even know that yet? If you really want to know, put the intake on the heads, and flow bench the heads with the intake on it like Blackbird did. that's the best way to answer the question.

Think about this too -- he has never once stepped in here to defend himself. So the discussion has been very one sided. His intake has several motors hitting 800 at the crank. That means it has to be flowing 380 minimum.
Just wait til Darth breaks the internet after dyno and track time. Just like he did with his Mamo top end stock 170k bottom end LS1 did on multiple dynos and 2 passes at the track.
Good luck Darth. Hopefully that pushrod comes in soon. I want to see GH rolling
This ^^^. Mamo stuff is top notch. All of it. Proven over and over and over again. Dynos, track wherever. It's just not all posted here on this site. Most of it isn't actually. Not all of my stuff is even posted on here and I like this site a lot. Darth has proven Mamo stuff personally as have I. Even the guys that get all pissy over something random with his stuff make insane power. He's for sure doing stuff that other builder/fabricators aren't. His LS7 heads are unmatched at this point, especially for a street style car. I'm sure other builders will catch up here soon though. Good builders always learn from other good builders and fabricators. You can't be good at building or fabricating if you're not willing to learn.

Nobody here dislikes you, including me. Darth tried to explain the situation, and I hope you accept it. I think you took some stuff here wrong.
Just know, if you put stuff out here, get ready for reactions, some of which you might not like.

I remember a quote from Arnold Schwarzenegger, but not who it was aobut. "He never convinced me to become a vegetarian, but he did convince me that a vegetarian could become a champion body builder."
Dad got to meet him years ago when he actually was a body builder and was giving info/lessons.
Guys, what do you think of this NA test?
Using CNC trickflow LS7 heads with an msd with a stage 4 Brian Tooley LS7 cam
247/258 112lsa+3.
Not very impressed with the rpm range or torque curve.
What do you guys think happened?

I missed the compression ratio in the video somehow. I suspect it was low-ish, as they were planning for boost. Other than that, it appears to me the intake ran out of steam or possibly the TB wasn't opening all the way. The way the power curve flatlined up top, that's exactly what my fast 102 did in my 346 build when I went to the MSD.
Also, I'm guessing that's an out the box MSD. Out the box, msd does not do as well as the fast. Both ported by the same person, the msd beats the fast. This was confirmed on dyno testing and by 99Blackbird in his intake airflow testing. The MSD just responds really well when ported

That engine should have revved out to 7000rpm.
Also Darth, I spoke to Tony on the phone earlier today for about an hour.
We spoke about your build and a few others he has done as well as the guy from Australia Mickeyinks.
Will PM you some questions about it.
I was about to make a deposit but not till I'm certain on which direction I want to go.

Don't know what went wrong but those things you mentioned might actually be it.
