Spoke to Robin Lawerence and several other Holley reps regarding the shorter version of the HiRam. They stated on the engine dyno it made the same horsepower in testing as a LS2 intake manifold. Sad part is they sounded excited about that? But it didnt feel like the Holley guys there had any 1st hand experience yet because they said it was just tested the week before and they were rushing to get it to SEMA and only knew what they had been repeated from whoever 1st hand tested it.

LS2 intake manifolds in our experience are quite terrible compared to most other better options. So it will take some independent testing to see how well it really works.

For those curious I took a few measurements, 2000 trans am stock k member, stock valley cover.

Valley cover to bulge under cowl=7 5/8
Cylinder head mounting point/bottom of intake port to that same bulge= 7 3/4.
Valley cover to top of wiper area(assuming you cut the bottom of cowl area)=8 3/4 or add another 1/4 for the valley cover and your around 9 inches.

So your basically around 9 inches before you start having series problems. I dont think it will fit without some sort of trimming to the cowl area not to mention the bottom side of hood in that same spot would need some grinding off. The big question is the rear of that intake, how far does it go forward before it reaches the 10 inches in height..looks like it goes from under 9 then slopes up to 10..would def be close on the fitment.

guess I will be sticking to the FAST 92...

I still think for a boosted application this will perform much better than an ls2 intake...

Very interesting. I saw it there, and it's cool looking, but again, the question is will it fit, and is it a better option than a FAST 90/92/100 on a boosted setup.

I agree.

Does anyone make a shorter motor mount? If some how it fits,makes good power and the price stays under $700 I'm selling the fast 90 sitting in my closet and the bbk that's on my car now.

Good question. Be careful lowering the motor too much though, because then the oil pan gets below the kmember and you may have ground clearance issues.

I like the looks of the intake, but looks alone aren't worth hacking up the car to make it fit.

If it performs better, and can fit, I'm all for it. I'll sell my FAST 90 in a heartbeat and get it.

So any other updates or info about this?

I'm surprised there's no buzz about this thing.

It looks like the base is a version of their 2 - 4 barrel carburetor intake. If I am correct, that is a "dual plane" design. Most dyno tests I have seen on LS engines with the dual plane intakes show a nice gain in torque below 4000 RPM over the LS6 type manifolds but less peak horsepower and RPM ability.

I must note, the tests I have seen were based on the Edelbrock manifold.

But remember, boost changes everything. Holley came right out and said that it was made for turbo/blower setups. Obviously it wont perform as good n/a if it wasn't designed to. That's like expecting a turbo cam to perform the same as an MS4 n/a...

One option to lower the motor would be to use the 1/4" k-member spacers used on the Maggie MP112 kits.

Yes boost does change everything but if the intake sucks, it's still going to suck under boost. The LS2 intake is horrible and if this performs anything like the LS2 its not worth the money. I would love to sell my LS6 intake and buy the Holley but as it stands its the best bang per buck. Looks great though.

I'm with you there. Looks only go so far. If it was even with an LS6 intake, I'd jump on it and find a way to make it work. ****, you could probably get away with lowering the kmember up to 1/2" with longer bolts.

LOL. It literally looks like their 2 - 4 barrel carburetor manifold with injector bosses cast in and a plenum bolted on top. I could be wrong, but it appears to be a makeshift solution' not a purpose built engineered piece.

Having seen the base of this intake (dual plane dual 4bbl) I think it's unlikely that it will outperform any stock intake. Just the opposite is what I would expect. Lots of sharp 90deg angles and ports that appear to taper from small to large makes for a torturous air path.

Regardless of performance or lack thereof, by the numbers it still doesnt fit under the cowl...Its right at 10" at the back end which is under the cowl. Not worth losing your wipers for!!

So if it doesn't perform that great and it won't fit most LS1 applications, why did they even make it?

It sounds to me like the LS6 intake is still the best bang for the buck with the FAST intakes even better.

I saw that it's on Summit's site. http://www.summitracing.com/parts/hly-300-126

Is it worth taking a risk on, who knows. I'm running 15psi of boost, so I'm sure my original FAST 90 is leaking like a bitch under boost, so who knows, I may try it.

Go for it. I wanna run it this spring but would love to see how it fits before I buy it...
