or these :-)

Those are definitely TSW Nurburgrings. I know this because I have them

Note: I suspect the figures quoted are at flywheel, not rwhp.
It would be very unusual to quote rwhp in the UK.

Conversion.

This begs the question then, why hasn't anyone designed a new intake manifold to remedy the problem?

True, i assumed they were at the wheels numbers as if it was only making 177 at the crank standard then i think i'd be returning mine and asking for the missing 23 horses.

love those numbers

I thought that too for a second, but that can't be. How can it only make 3 hp and lose torque with a tune and full exhaust? Stock engine is rated 200/151.

It's gaining 20+ BHP, but on a baseline of 175/8 BHP - bringing it up to the 'sales/marketing' figure. The few I've seen tested over here have all run about 175-178 BHP at the fly.

I see what your saying now. Thanks

I saw somewhere thats its popular in the boxer engine world to remove the throttle body and have a individule flap for each cylinder.

Like the first couple of pictures in this thread.

Oh, I'd love ITBs, but that'd be an EXPENSIVE mod XD

If we can fix it using tumblers though, I'd be cool with that, as long as it wasn't TOO expensive, and too big a pain.

It's not popular at all, because it's difficult to tune and make work correctly.

Those aren't ITBs, those are what they call TGVs (Tumble Generator Valves) and they come AFTER the original single TB. They were used on the WRX/STI for emissions reasons, they create an obstruction which swirls the air and creates more complete combustion when the engine is cold/during startup. When performance levels get high enough most WRX/STI owners remove them. The JDM EJ207 engines do not have them.

As for the BHP/WHP debate it would take Litchfield to answer that question. Either way you just have to look at the % gain versus the raw numbers. The stock 1/4 mile trap speeds most magazines and some users on here have run are consistent with it having right around 200hp.

I don't think it's the manifold persay, the manifold has been fine for FI applications. It has to do with the cams, VVTI, etc. The whole package together just can't push enough air through the engine during some of the transitions.

[jm1681]

One says manifold, another says cams and timing.

If it were cams and or VVTI, one would think it would be a WHOLE lot easier to eliminate in tuning. That just doesn't seem to be the case though. I mean, I'm not keeping up terribly well with what's being done in tuning, but I don't recall ever seeing a dyno withOUT the torque dip.
