Which intake manifold for road racing
It would be extremely helpful in all threads if guys that had NO experience with something just kept quiet.
Saying you are going to buy something or suggesting you have something just for the hell of does no good.
I have performed quite a bit of intake manifold testing. AMS has performed more I am sure.
I have NOT tested AMS's or Full Race's (didn't even know they made one actually) back to back to our ported stock one.
I did however test the stock intake, extrude honed intake, our hand ported intake, stock throttle body and our 65 mm modified stock throttle body and one other sheet metal intake manifold.
To finally get to the point. Back to back dyno tests on NUMEROUS cars have left us running ONE combination.
My RS, my brothers car, out Time Attack car, Jarrod's car etc., etc., ALL run our hand ported stock intake with our 65 mm throttle body. Let me remind you my RS ran 9.97 at 142, my brother car ran 10.1 at 144 mph and Jarrods with our 3065 has run 11.5 at 131 (Jarrod's an amatuer driver
I just put someone in my car that CAN drive and call it a day! haha
I am actually doing more intake manifold testing this coming week. Just got my RS back to the shop, as you can see from our fuel system post.
My recommendation for now atleast is ported stock and the 65 mm. Both pieces are only $375 with your exchange.
One more thing. We are running the HKS Kansai intake on our black car and Al's car. Very expensive. The majority of the other high HP cars that want to run an aftermarket intake manifold we have bought and used AMS's. Very nice high quality piece. As for actual dyno testing though, we have not done any back to back with theirs VS our stock modified stuff. Martin has assured me there is power increase and I have grown to trust him.
I like using as many stock parts as I can. You pop the hood of my car and there is no way in hell you are going to think it makes 600 whp and run's 9's

Here's the Full-Race mani:
I think for $200 more money the Cast HKS unit would be higher on my list than the sheet metal plenum Full-Race unit.
Rumor has it that Virtual Works (The other sought after Supra Mani) will be building an Evo intake mani this year also.
I'd really be interested to see some back to back dyno numbers from the HKS vs. the stock ported mani you guys run.
And yes, any manifold with additional plenum volume will cause a reduction in boost response since the plenum is larger than the air demanded at low RPMs in order to provide more air at high RPMs, which is exactly the point Ted B was making. You have to pressurize the extra volume in the manifold which causes the "lag" the same as an improperly oversized intercooler.
Anyone know when that full race manifold is actually going to be on sale? or is it?
From a road racing perspective for sure stay on the stock manifold especially if the head is stock.
Our time attack car runs an extremely aggressive port on the head 1mm over valves, custom cams, Our 2.2 stroker, 9.0 comp and a new turbo, similar in power to a GT35R .63... For now we have port matched the stock manifold and added a 70mm throttle body to it.... I think we will have it on the dyno toward the end of the month. we are working on a new K-Member that has the car stuck on the lift.
I would love to see which manifold works the best out of these. AMS VSR, Full-Race, HKS, What we did to the stock one, a stock manifold and just for kicks the Ebay one that looks cool, but will probably explode.

as for your ported stock, how much more lag/power difference? and as for the new testing, what are you testing?

greg- what is this turbo you guys are using and what response are you feeling from it?
i to have a cosworth crate 2.2 with the cosworth head on evo9 with aem ems- and waiting for a custom turbo as well. what is the 9.0 comp?
i to would like to know the hard data on the listed intake manifolds.
it doesn't seem that this upgrade gets talked about much but yet all the major players like yourself, buschur and ams are using some sort of upgraded intake manifold- so in my eyes this upgrade must be worth something.
The stock ported with our TB is worth a solid 15 whp on a decently modified EVO and has NO losses ANYWHERE in the power band. That is VERY important.
socalmr,
We are running an intake manifold ONLY on our black drag car. It just didn't seem right putting the stock intake/throttle body on a car with full 3" i/c plumbing and a GT42R turbo.
The Kansai intake cannot be used on US cars with ABS. It has to be removed or relocated. Nice part but honestly, not sure what if any power it is worth over stock.
The Full Race part looks good but it looks very similar to the Ebay unit if I remember what it looks like.

Yes, the Full Race mani is available already, they finally added it to their site not too long ago. The throttle body on the Full Race mani is really nice, nothing really close to it available anywhere else.
Sounds like the stock ported mani would be the best. If Dave said it, it must be true. I would however say from what I've seen if you absolutly need an intake manifold, and plan on doing some drag racing. The Magnus seems to make good midrange power, but the AMS will make more peak power and you dont need to run as much boost. On a back to back dyno test the Magnus needed about 12%-15% more boost to make the same power as the AMS did.

dave,
what is the turn around for this job if i overnite you the parts?
out of curiousity, how much do you know to sand off when porting intake and exhaust manifolds?
i have your port/coated exhaust mani right now and i will let everyone know that i most definitely felt a power increase. so obviously you know how much to sand off, just curious on how do you know how much?
and lastly, i am 99% sure i am going to go with your ported int. mani/tb - can you email me the correct way to take those things off or point me in the right direction?
thanks

The hardest part of taking the intake off is the bracket that goes between it and the block. It will take 3-4 days for us to port it and modify the throttle body.
When you send it take everything off the intake except the hard fittings that are screwed into it.
