Personally I think keeping RPM down promotes engine longevity. Mine is built...forged everything with good springs, but I still don't buzz it very often.

Well there's your problem
these manifolds are for race cars not street cars. Every engine I've ever built for myself the goal has always been 40-50k miles. If it lasts that long in happy. I know when I build **** and through the sauce at it it won't last forever or even as long as stock. Nature of the game I guess. It really depends on what spectrum you want to lie on. Fast, reliable, and cheap. You can only have 2 of them. Problem is people on this forum want all 3 🙃

It ain't the bottom ends you have to worry about......especially built. It's the valvetrain. And with the right stuff running to 8k can be done even with hydraulic cams.

If i had a built bottom i wouldn't stop till i was shifting at 8k......atleast 7500. Preferably closer to 8500. I've been spinning my bolt on ls6 to 7k for 90k miles. Just bumped the limiter to 7300 to.

Idk.....it smacks the hell out of the rev limiter way to easy at 7k. If you do the math on the gear and tq it says i should be shifting higher to.
You have to cam it to make power there and use the right intake like Goertz is offering. Among other things.
I would never build a ls motor for a hotrod and spin it less than 7k. They like to rev

Did we ever get any results on an LS engine for this fancy intake? Or any back to back tests for that matter? How much did that fancy Mustang pickup over a Boss 302 intake manifold?

Your particular setup may not respond well due to having high backpressure. Squeezing a higher RPM LS through a 75mm hotside isn't the best case scenario, now if you had two of them... winning!

At some point the long *** runners ofa stock intake is gonna be fighting moving that much air. My bet is it's way before 8s. Can it be done .....sure. Is it gonna be as consistent and fast.....likely not.
It's already known those oe plastic intakes don't flow as much as the heads do.

Take a turbo 6.0 with ls3 heads and swap from a ls3 intake to a Holley high ram and see what it nets you....
Talking 8s cars not these 1500-2000hp cars like g1 works with. I'd imagine in that power range they are spinning them up pretty high and can take full advantage of a g1 intake.

A ls3 intake don't flow what the heads do. I've ported/rod modded some ls3 intakes for guys on here for na stuff.
Pretty much every test I've ever seen on na vs boosted parts shows if it works na then it will work with boost.
Now if you're not willing to spin it over 6500 rpm then you may not see much for gains.......but eff that. I mean **** if your goal is to go fast don't limit yourself to that rpm range.

Holy **** this place is full of ******* morons
G1pro, don't waste your time aruguing with the morons
People who aren't morons understand what is being built and the reasons they want it.
I can't believe this guy is getting his ballz rode for something that customizable with quality fab for that price. Christ

If you can run 7.6’s with a stock 5.3 and a Holley hi ram how much would this intake pick up on a setup like that shifting at 8300? Give him one to test until then no proof no care... if it works your advertising is free and they sell like crazy.
The OP’s post sound awful like fat **** motorsports hocking 417 intercoolers with no proof and trust me it works propaganda. Until a back to back test is made he can keep selling his stuff to the LS7 guys with money to waste. He already said he doesn’t need to sell his stuff here so who cares what we say about it.

I take it most people replying in this thread haven't seen what eventually happens to factory plastic intake manifolds when the boost levels rise above 25-30 psi. You will start to get stress cracks and fractures and eventually it will blow up. You will need some sort of metal intake to keep it together and I don't see why this wouldn't be a good option at that power/boost level. At the least it's another option and a relatively good priced one at that compared to the others that are available. Sure I would like to see some testing in a back to back compared to the stock manifolds as well just because I like data.
