I will own this intake!!!! check it out!

[datsbad]

Has anyone seen this thing . it looks way cool . hope it works as good as it looks . http://www.harrop.com.au/root_folder/harrop_manifolds/amfd7022-00.html


Steve ???? what do you know about it . ????

[Steve1968LS2]

Old news ;).. Payton King and I have both been drooling over this and getting pricing from Australia..

Nice product with lots of wow factor and a decent bump in performance..

[datsbad]

i knew you saw it !!!

how much is it , what required ?

[Steve1968LS2]

i knew you saw it !!!

I will call ya tomorrow.. Im too lazy to type it all.. lol

[Ralph LoGrasso]

How does it compare to a FAST 90/90 setup(or even a port-matched 90/90)? Any idea on what kind of gains you would see? It can't be all that much? Or can it?

[Stokes]

I will call ya tomorrow.. Im too lazy to type it all.. lol


That's not fair!! :crying:

[Nutsy]

I wonder how this setup would work with a twin turbo setup?

[MuscleRodz]

I have not seen that one but I just saw on TV the other day another one that looks alot like what is one the MULE for the LSX engines. I don't remember if it was FAST or Edelbrock?

Mike

[ViperBlue68]

more info on the other one please?!!!!!!!!!!!!!!! or pix???

[MuscleRodz]

Not the one I saw on TV, but here is one from Kinsler.

There is a post about this manifold over at ls1tech.com.

If I remember right they said that on an otherwise stock LS1 it would pick you up 30 horsepower/torque.

Also if I remember right the price tag is over $3k.

[Steve Chryssos]

LSX engines are awesome--no doubt. But they are the ugliest, most boring looking engines ever produced. Just my opinion and I know, I know, it fits under a low hoodline. But when your hood line is NOT low (i.e old muscle car), it just plain looks like someone stole the top of your engine and left a pile of small intestines behind.

Tony Whatley's blown LS1 looked hot! 'Cause it had an induction system that sat higher than the valve covers--the way nature intended it to be. Same with this deal. It looks totally awesome. For $3K, I can only assume that the Magnusson blower will make more power per dollar.

I'll bet Comp or Holley or Edelbrock could build an intake that moves the plenum above the runners. Output should be unharmed and cost should be on par with current "under-runner" designs. Hide or cover the hideous coil packs and you've got beauty and the beast all in one.

I'd keep this idea secret for my company, but I just don't plan on getting into the casting business anytime soon. So the company that steps up and de-ugly's the LS1 will make a killing!!

Feel free to send me a royalty check.

Well only problem is 90% of the LSX market needs the low hood line.
Even the guys that put LSx engines into RX7's and Miata's need the top to be as low as possible.
The market isnt that big although it is growing

You could always buy the GMPP or Edelbrock LS1 carb intake and modify it to EFI and then you'd get the appearance of the old SBC.

I agree. The 1x4 deal going on one of the cars I'm involved with. But still, I can't help but wonder if more muscle car and street rod builders would step up to LS1's if a mass produced front inlet/top plenum intake existed.

[Damn True]

Honestly, I am shying away from it because they scare me. All those wires and tubes and sensors (oh my!) that do stuff I don't understand, the complexity of tuning the OBDIII stuff, the differences in mounting, having to move the tranny mount, cut the tunnel etc etc.

As of now, and unless someone shows me that it can be done easier and cheaper than something more conventional, it's more than I want to get into.

No doubt that they are great motors, and stinkin light (which is attractive), but like I said.....scared.

[Steve Chryssos]

LS1 engines are a steal by comparison--direct comparison, that is.

The problem with Ls1 comparisons is that folks compare basic Gen 1 specs to LSX specs. In fact, if you tried to match the LS1 specs with a gen 1 engine, you'd add up cubic dollars. Comparing a 23 degree gen 1 small block to a 12 or 14 degree LSx motor is like comparing a gen 1 small block to a flathead.

For example you CAN buy 18, 14, 11 degree raised runner symmetrical port heads for a gen 1, but all said and done, the conversion parts alone (heads, pistons, exhaust, intake, valvetrain, valve covers, etc.) are at least 6K. The runners and chambers come semi-finished (that's how arec engine builders want em) so you gotta spend money on porting. And they really don't configure these things for street cars because they figure we won't drop the extra 6K-plus. They desing the specs for racing only.

So take every trick in the book that has been learned during GEN 1 race engine development (shallow valve angles, symmetrical raised runner ports, priority main oiling, spread exhaust ports, fast burn chambers. etc) and add it up. You'll drop $30K on a gen 1 small block that's pretty unruly on the street.
All of these cool features are cast into every darn GM pickup, SUV GTO, and Corvette that falls off a GM assembly line.

Did you just call my old LS1 engine ugly???

lol

Actually the next one will be much better looking :)

If it wasn't for the fact that I would be mobbed with hate by the Ford guys I would put an LSx into the new 67 Mustang project.. lol

I'll agree with you here, heavily. To match Gen I performance with that of the Gen III takes big bucks. These engines just take so well to mods, it's ridiculous. For the past year or so, there have been guys pulling 500rwhp out of stock cube 346ci LS1s. Sure, it's a max effort build, but that's an amazing feat, for sure. $3-4k and a pull-out LS1 will get you 450+rwhp (525+ at the crank) or more these days. N/A. C'mon Steevo, ya know you want an LS1 under yer hood. :headbang: Come join the intestinal intake manifold club.

[bookends]

I saw this one a while back, it's from Australia but I couldn't find any more info on it.

[chicane67]

Ahhh. But then there is the king of all manifolds for the LSx.

[MuscleRodz]

Do this Steve. Bolt on one of the new carb manifolds for the LS1 and then use a TBI setup. Best of both worlds. I have a fix for the coil packs but it is only in the design stages.

Mike

[MoeBawlz]

Man i wish i had more access to an LS motor...

I have all the computer power in the world here to design anything and the knowhow... as well as a complete machine shop with full CNC capability... BUT NO LSx MOTOR!!!!

However i have to agree with everyone else here... the LS motors in old muscle cars just doesnt look right. It needs to look more like a motor that would go in these cars, more metal to it... and while the plastic variant is nice because of weight savings and clenliness it just doesnt look right in my opinion.

[Diognes56]

That thing looks sweet.

It Looks Right In My Car : ) .....i Guess It Depends On What People Like To See ...like Me ...i Hate Seeing A Big Ol Round Filter ...thats The Ugliest Thing In The World Lol

[RobM]

next motor in my car will be a carbed ls1. I really don’t think i need the drivability of fuel injection.(other then the gas mileage) i think the carb manifold looks cool and is an awesome setup for those of use who don’t want all the wires and sensors. the way i see it is you get a lighter small block with far better heads, 6 bolt mains, the carb manifold looks like a race manifold due to its air gap style design, crank trigger ignition, and it can all be done for about 4 grand. and that from what i know would give you 450 hp at least to the crank

Belongs to the HRT 427 concept :crying: Monaro (GTO), was very very close to going into production, pre orders were already filled.

Inlet & lots of parts made by the same company, Harrop Engineering as inlet in topic discussion.

Here's a couple of links on HRT 427

[bookends]

thanks for the info, I've been drooling over that intake for a while now. the hrt 427 concept sounds very similar to the ZL1 supercar camaros over here. they were produced by GMMG inc. http://www.gmmginc.net/ I live about 30 minutes from where they produce these. I've got a couple of friends that work there. these are truly amazing cars.

[BigBronco]

It seemed like a very cool product. I just wanted to see some flow sheets and what not. ALSO, if you guys want bling under the hood... you should always check out the sheet metal intake on our Hugger Orange 99 SS on our ls6 motor. It had all kinds of Bling. I will try and get a pic up of it tomorrow.

Does make some good numbers, 588 hp @ 6,600 rpm & 524 ft lb @ 5,350 rpm out of 383 ci here
