We need a sc lid too.. I port them but look at this crap. That's literally dang near a 90' turn down..air flow LOOOOOOVES that , lol.. I will post pic of how much I correct it and in the pic of the ported/corrected ons , that's only HALF done , I open that opening up more and continue tapering down that turn and then smoothen out the inside and antiheat coat the outside.
correcting and porting the lid , elbow ,manifold and sc inlet really really helps actually..

Actually I would love to do a complete redesign. Plan is at some point to make new horns and a front mount kit.
I am sorry , I know I am a bit slow updating the thread.
The intake manifold is released. *The non-ported version. Ported version and turbo version will follow.
I sent a ported version to a customer in Dubai, for further testing. Turbo version testing will happen in the UK as I do not access to such car over here.
So what everyone is waiting ... gains! Gains in the whole rpm range.
Huge gains from the 2500 to 5000 rpm with +40Nm and 15Whp at 3000 RPM and +10Nm and 12 Whp at the redline.
Results on a TPE Precision non-ported manifold vs Original non ported intake manifold.
Test Car spec:
16% Supercharger pulley
0% Crank pulley
550cc Injectors
Exhaust cat-back
TPE Precision charge pipe.
TPE Precision prototype cold air intake
TRS Performance ECU Tune
The minus 2 kilos, is another plus. That's the beauty of this technology. You can have a very strong but lightweight part, plus complete design freedom.
The kit comes with bespoke viton seals.
OK, let's see if I have this correct. In addition to my other mods, if I spend $1,200 on an intake, $462 on a charge pipe, $635 on a tune and an undetermined amount on a CAI (let's estimate $2,700 total), I can make an additional 15whp? Someone make this make sense.

I will speak for my car, as I do not know how other cars behave. Mine for sure it was not close to the advertise numbers.
Additionally it is not only the numbers at the redline, but how overall a product behaves in the whole rpm range. I totally get what you mean about the overall cost. That's why my aim is products that give gains in the whole rpm range.

did your car make more or less than advertised gains?
Ok,Kudos on your intake design. Thirty percent increased flow but wouldn’t this benefit from a thirty percent larger throttlebody. Stock t.b. would be a bottleneck. Also increased air flow would call for a remapped ecu more aggressive spark and fuel curve?

Just my feble 2 centavos.
The TPE supercharger intake works perfectly with the alternate 65mm throttle body BMW part that you can purchase for the R53.
I had to drill & tap a small fitting onto mine for the vacume hose the the stock 57mm one has standard. 57mm is small for a 1600 & the stock can only be bored out to 63, possibly more but I don't see anyone offering to do it larger.
With the replacement TB, intake pipe & this new manifold you are definitely going to want a re-map, as I will also be doing once mine turns up

We can provide bespoke charge pipes !
Any diameter or bolt pattern is possible

We have race cars as we speak testing our manifold with enlarged th.bodies as well.
So far gains are very similar with what we saw on our car.
The biggest surprise was IAT reduction.
Will upload more data once I have more feedback from the race cars.
