Kinsler EVO intake manifold....rad
FWIW, the HKS manifold picture above appears to be a copy of a rally manifold that either Audi or Benz (can't recall which) developed in the 1980s.
It isn't how one picks up the signal, but rather how the signal is processed into something accurate and consistent enough with which to base critical calculations at all pressures and rpm.
So far, Autronic, Wolf, Megasquirt. All running with reasonable success, but . . .
An 'easy fix' is already running, but everyone realizes it leaves something to be desired where tuning accuracy and reliability is concerned. A multi-thousand $$ ECU (e.g. Motec) with MAP signal correction tables is not an acceptable alternative.
I am reasonably familiar with it, but I wouldn't touch it for several reasons.
There are street turbo setups with ITBs running around here and there, but just making it work well enough to run is neither the issue nor a satisfactory end point.

I think at the end of the day the question becames is anyone going to take up the challange and spend the money. When you have the right tools everything is easy and possible!!!
Thanks. Fortunately, it has been mostly (but not completely) resolved to our satisfaction (insert a credit to Anders here). The expectations of others may differ.

There is another company called Elbow Racing from Australia that has a intake manifold identical to that HKS one which i dont want to flood this post with other peoples products but going off all the testing done by Archiebabe was the best design having a separate cone going into the plenum as far as even distribution. Problem is there is only really one software program out there which the big boys use (GM, Mitsu ect.) with a yearly license price of $50K that will get you as close to real world results as possible. I believe in Arhciebabe's thread he used CFD modeling for thermal dynamics as well as flow to come to the design you see above. It would be nice if someone could get there hands on that license for a little while to see how things work out. Problem is $50K for license plus say around $20K-$30K for production costs is allot of overhead to recoup on selling intake manifolds!
On a side note i think Kinsler will figure out what works the best and go with that design. They never have made a product to my knowledge that has been second in any aspect. Expect i nice price tag when they are finished but also expect a new level of innovation to come along with it!

Just turn up da boost! The first 2 days we spent on an EVO head we were 10cfm better than the Cosworth head we had, but we still had a stock size valve and a fairly small port overall.

Of course I forgot...everyone already knows everything. That is why I keep seeing EVOs with cold fuels, mechanical pumps, small injectors, top feeds, 60 degree seats, and raised ports.
It's become apparent that the Cosworth head is not what we'd consider to be a 'max power' effort. But in all fairness, it isn't advertised as such. Consumers tend to just assume that because "Cosworth" is stamped on it, that it is.

Definately not a max power effort, but still better than most of the heads people are selling to customers. If I remember right it did 265 @ 28 on my bench. Does your head flow 300 @ 28 on an SF600?
We saw around 295cfm @ 28" on mine before calling it a day. With the Cosworth on the same bench, same lift, same settings, we saw a max of 250cfm. But all things considered, my current head outflows it comfortably in all lifts. Again, this is no slight against the Cosworth head, but better results can be had.

Maybe that's because one of the top head guys left Cosworth and now works at TRD. Of course, Cosworth doesn't put that in their ads.
