Im getting a headache page flipping - both together...

standard 3.2 maual

[Kevin Wood]

There is not a lot in it, if anything I would say the on the previous the torque curve is steeper

Exactly.. Just what you don't want.

Same power output (within accuracy you can expect from 2 different dynos), so the torque at maximum power RPM must be the same (since power = torque x RPM / 5252), yet the curve is steeper meaning the modification has lost torque at low RPM - exactly what the multiram is there to maintain.

As for the graph and if you look at bhp (which seems to be what the op is looking at) you get

RPM	Modified	Standard
2000	68	72
3000	108	117
4000	154	164
5000	197	208
6000	215	218

So less bhp across the rev range due to the compromised torque curve. 

Nice, better go buy yourself a nice cone filter to

Yep - a couple of hundred quid should do it.

Indeed. Could probably graft a set of them them onto the bottom half of a V6 manifold reasonably easily.

Or 2 sets from a couple of Triumph triples ?  :-/

Some of the bike setups are single bodies bolted together IIRC. Ideal for this sort of thing. GSX-R 750 is a good donor, as I recall.

Getting cool air to them could be a challenge, I suppose. Bulge in the bonnet, anyone?

[albitz]

Just extend the ram air pipes already attached to them. Flexi hoses running out to the front to catch plenty of cold air.
Would imagine a set of gixer750 bodies might be a bit small for a 3.2 v6 ? :-/
Perhaps a set from a Triumph rocket 3 - a 2300 triple.

[Marks DTM Calib]

A pair of these:

Is there an echo in here ?

IIRC they're about 42mm so probably about right.

wonder how they will work on DBW cars

[Nick W]

I knoow they're a bit bigger but how about K-series Rover throttle bodies? They're 42mm if I remember right, and you can't give them away.
I made some adapters and a throttle linkage to convert a mate's Dolomite Sprint to EFI using the original manifold and a pair of these. He sold the car before I finished the job, but next step was to turn some injector bosses and weld them in, plus fabricate a fuel rail, using Carlton injectors and regulator(chosen because they were in the potentially useful bits box). We were expecting there to be about £25 in materials in the entire job.

Not sure I'd like to make a linkage for six individual bodies though!

Just to let you know the 'modified' dyno graph is the 3.0 and the 'standard' is from a 3.2........
