** REVIEWED AND UPDATED POST 24th JULY 07**
Hi All,
I have made numerous changes to No. 1 prototype of my fully cast-aluminium inlet manifolds for the V6 3rd Gen Magnas. I hope to be evaluating it on-car during week-of sunday 9th december 2007.
What's an Inlet Manifold? Didn't know there was a first prototype? Then click here and learn-> https://www.aussiemagna.com/forums/sh...light=manifold
The replacement "EZ Plenum" is made of cast aluminium, with HPC being investigated as an additional cost add-on. Each manifold will be serial numbered underneath (out of view) to ensure that the item retains value as part of an exclusive production run.
The #1 plated EZ Plenum will be donated to AMC to be raffled for club fundraising and drawn at a public AMC event. Details to be finalised.
Ok some more info that I can make available:
* Will fit the 3.5L V6 and the 24valve 3L V6 motors in the 3rd Gens.
* Strut braces will continue to fit with the manifold in place
* The item will look OEM to any non-magna expert
* All oem ancillary brackets will be supported or new ones supplied, including the plastic engine cover.
* EGR function is NOT supported. If you really want it, you're most welcome to modify it accordingly.
* WILL function safely and happily with STOCK ECU!!
* Does NOT require ANY additional mods to the car. While additional mods such as cai, flowed tb, fpr, extractors, sports exhaust, thermo spacers, tb hot water bypass etc etc, aren't required for the manifold to produce powerful results, they will certainly enhance the manifold's contribution to power and fuel econ.
YES - my initial prototype improved fuel economy just over 1L/100km in my AWD as it improved engine efficiency. That was WITHOUT extractors.
"But I own a 4cyl or a 2nd Gen"
Great, if it has a plenum and runners, I will be looking to provide a replacement manifold.
I presently don't have any tangible power figures to provide people, I WILL DEFINATELY be aiming to obtain dyno figures and a 1/4 Mile time with AND without the manifold. This testing will be done using a 3.5L TJ Manual with extractors and 2.5" system, since my car is an AWD and is harder to find a dyno in Newcastle. And since 98% of AMC cars are FWD, this comparison seems more relevant, as is the mod level of the test vehicle.
I am expecting the price to be between $800-$900 for the V6 unit. Pricing and results of testing will be made available before seeking any sort of commitment from anyone.
What I do need tho is an EOI from AMC and non AMC-ers that are interested in such a mod, even if your tax chq wont surface until september, i still need a feel on whether this is worthwhile pursuing for the team.
Just a quick:
"F-yeah!
3L V6 3rd Gen Manual"
Will be fine.
Thanks folks, peace.![]()
