Surfing the net I came across Harrop's web site in Australia, and found something AWESOME!! They have an intake for the LS1/2/6 engine that features individual runners, each with it's own throttle blade. Here's the link: http://www.harrop.com.au/root_folder/harrop_manifolds/amfd7022-00.html check it out. This is the same kind of intake layout used on the BMW M cars not to mention almost every race engine ever built. It's not cheap, about 3800 US, but still half the cost of a blower. I've emailed them, as soon as I hear anything I'll post it. Check out the pics and dyno results.

I got an email from them today, the unit is available, none have been shipped to the US yet apparently as no one here knows about it. The ECU has to be reprogrammed to use speed density mapping instead of mass air flow which they have available. They also have a blower system they call "stealth". Talk about "decisions, decisions"!

That blower system is the one (slightly modified) that the fastest Monaro/GTO runs 10.22's! Or at least that's what I hear.... :cheers

I'm going to email you the .pdf files on both the blower and intake they sent me as I can't seem to upload it due to it's size.

Yup, that's it! How'd you do that? LOL
I actually give the credit to b_a_betterperson, he hooked me up and showed me how. It's really easy but I'm really crappy at explaining things so you might try to pm him and tell him I sent you, he's cool as hell! :cheers

Been looking at this for over a year now. I just can't see doing a speed density tune for 8 individual throttle bodies. The tuning alone would be in the thousands based upon dyno time. $hit, its hard enough finding someone in the states that can do a s/d tune on a standard single throttle body based manifold, let alone 8. Beautiful set up though. If I had money to burn, this would set fire to it. On the other hand, I would much rather have a turbo or s/c for that price range. A h/c car would be more worth the money than this. This manifold is more for looks than anything.

wow

Is that RWHP? Does that intake and setup give the '04 404rwhp? What will it do to the '05? Does it come with tune settings?

Yes, according to Damian Johnson at Harrop they made 400+RWHP with it. They are working now, to use dual MAF sensors and the stock ECU. They say the results were very close using either the stock or aftermarket (Motec) brains. Jeff @ LPE and I have been seriously discussing building one of their 427 LS2's with it. :D

The issue with turbocharging is the airboxes, Damian noted that a change would be necessary in order to pressurize them as they're not sturdy enough as is. :D
As we've discussed in our emails, I think you have something!!!!! Please keep us posted, if there is a way to make a MAF system work I'll buy the damn thing!!!!!!!!!!!!!!!!!!!!! :cheers
