Throttle body conversion

[Jonnycoupe]

Linear, predictable power and the fact turbo goodies are expensive

You must drive on go cart tracks. T16 Turbos have no problems on proper circuits.... well only when the K series engined cars are in their way

Keep the turbo engine above 3000 (where it should be anyway) and it fine for the track, btw T16 is too tall for metro

1.8vvc is cheapest way to 160+ bhp in a metro

Yep, this is in the back of my mind all the time. I think it would be more fun to try throttle bodies though I suppose I could sell the throttle body setup on when/if I get bored of it.

If you have nothing useful to post, please don't deride my thread. I would have thought it is fairly obvious what I meant. My coupe coming on boost on a roundabout is enough of a handful. I wouldn't like to be in that scenario at track speeds! I'm just trying to keep it simple and most importantly, cheap.

You haven't even done a track day so I don't know how you can say a turbo engine is no good on a track, there are certainly no roundabouts on tracks. Coupe are handful anyway

It may be nice having nice smooth linear power, its no fun getting overtaking on the straights with a weedy 1.4 though.

If you want Throttle bodies run alpha-N as suggested, the an aftermarket management solution will be needed, there is no way in the world you will run throttle bodies on MEMS. After you have probably spent over 2k on this 1.4k. You will soon be bored of how slow it is compared to how much you have spent. You certainly can't just stick Throttle bodies on and expect power without changing anything else.

There is of course the fact your asking how to do this on an internet forum....

Any powerful car is a problem when you boot in mid corner. Guess this is why you term the 1.4K is okay, its not powerful enough such that the the tyres have no problem with lateral grip and maximum traction force at the same time.

Just re read your first post. Mappable ECUs are good modifications to any engine, has nothing to do with them being turbo'd or not, turbos simply operate at a higher manifold pressure when you press the loud pedal. On all engines you simply optimise the fuel and ignition at many loads sites, (around 200 sites) based on throttle position and engine rpm (on speed density you use MAP and engine rpm and hence is why its favoured to turbos cars simply because MAP is a better indicator of what fuel the engine require)

Throttle bodies will total change the demands on the engine and how well the cylinders fill and certain resonant frequency effects. You'd really need the dyno to tune ignition correctly for the minimum timing for the best torque and it would certainly require longer than 1 hour of work.

Im of the opinion that you not really asking in the right place either, a motors spin off section of a computer forum is unlikely to found as much info as other sites out there.

You're probably right but I still value some of the members opinions who post here, yourself included
Plus, I think I've had some good info here
