The head can be welded, I had worse repaired a few years ago

 

Bumping this back up as I was thinking of going with this intake or a proflow, I like that I can keep the wipers with this and get the better fuel rails. Wondering if you ever got your engine back up and going.

 

I'd love to see some more comparison data for this intake. There's obviously a lot of hate out there, but I'm not sure how well founded it is.... The only actual test data I've seen was for a cathedral port running NA.

It's an intriguing intake for me. I'm running an LS3 intake on my procharged LSA and would like a little more top end (current HP peak is~6700) and have been eyeing this as a reasonably priced option. Certainly more cam always helps the top end, but from what I've seen it seems the stock LS3 intake wants to level off in the mid 6k's.

 

From any tests before...and of course the basic design alone, there is nothing to suggest this intake will be in any way good at lower rpm's

But then the same would apply if it was a $3k fancy name short runner intake. The fact this is cheap....little odds. The 3k one wont magically work miracles at lower rpms

So if it looks good to you, if it fits and you're happy that it will perform in the rpm's you want to use, then just buy it.
If you need more oomph in the higher rpm's, 6500, 7000, 7500 etc then the likes of this should have benefits vs any stock type intake. Anyone wanting that will probably not be concerned about what it loses at 3000, 4000 etc

They're all big V8's anyway so it's not as if any will be ***** at those lower rpm's.

 

Exactly, I know there is a lot of hate on this intake but some people also don't like fast intakes either and then some people love them I just sold a fast 102 now I'm looking for a new intake for my 408 s480 build when I talked to tick performance the guy I talked to said he was going to give this intake a try himself. I was looking at the proflow but I really don't want to cut my cowl, now the way I see it if someone goes with say this intake on a fi build and it balloons your out 500 bucks if you go fast and it cracks your out 900+ and I know there are people having success with fast intakes and some haven't this intake is new so time will tell but apparently it's holding its own according to above.

 

It would take years of service before any movement in the metal would be of any real concern.

Most people would probably go through more pistons etc than they would intakes through metal fatigue

 

I spoke with an owner of TT 5th gen Camaro that had recently swapped from a fast. His only complaint was a harmonic noise at idle. It would go away when you pressed down on the very top of the manifold. He plans to weld a machined billet plate to the top.

 

Did he say how lbs of boost he was running or any dyno comparison compared to the fast? As I know it will loose down low and gain up top but with twins it would be a interesting graph

 

It would definitely make a good back to back test !

 

He said he had some bugs to work out before the final tuning. But here's the car.

 

Apparently the intake works he broke 200mph in a standing mile.

You could do that on a stock intake quite easily lol....so hard to imagine why that would be proof it works ? Although of course it will work to run the engine.
I suspect the turbos and other mods had a little more to do with it.

 

Rofl his fastest speed with the fast was 196mph. Not saying this intake saw mad gains but the car hit 200mph with "bugs". I was simply just pointing the car clearly didn't suffer drastic loss while using this manifold.

 

Nobody is saying it will suffer a drastic loss...and certainly not in the upper rpm ranges where they likely are towards those speeds.

A back to back dyno of the FAST vs Holley would have been nice to see.

In fact, same could be said for any of the intakes, I still find it so strange dyno tests are so hard to come by, especially from their manufacturers who you'd think would love for customers to see them.....

 

Well we know one thing the fast intake didn't like it to much so he must have a decent amount of boost.

 

I wouldnt think he'd be using much over 20psi to achieve that sort of result.

 

I have a customer with a 8.5" tire Coyote that has been 4.70@156 with the Coyote version.

He has had no issues.

I don't have any data from the LS version except for one customer of mine who just put the "race" version on.

 

Again that doesnt really give any detail to the guy who runs their engine in the 1000-6000rpm range

Nor perhaps even say 4000-7000rpm range.

It just means...well not a lot really as there are probably loads of intakes that will allow the power.

But I certainly dont see what some of the mega $$$ sheet metal intakes would be offering over the Chinese Holley intake in terms of performance per $$$

At $500 or so, these are damn good value no matter what way you look at it, and with their low height. Most wont give a **** low-mid range changes simply because it will fit their car/hood easier than the taller intakes, even the cheaper Proflo

Win win really.

Now they just need to make a more crossover design with slightly longer runners but still the low profile

 

Interestingly, Holley seem to have a huge range of intakes for these now.

Whilst more money, for those wanting a cooler above the intake, they do this ? Would maybe help some as it has a much lower profile than a cast HiRam

or what might be a slightly longer runner that could be cut up or adapted ?

I was mainly making that statement based on the comments that the intake will come apart or have sealing issues.

I personally wouldn't put one on a street car with a wide power band.

5000-7000+? No problem.

The main advantage a fabricated sheetmetal or a billet intake would have over this intake is cross section.
