Throttle bodies

[markh]

Am thinking of fitting a set of throttle bodies to my Chimaera, has anyone here had experence of fitting/running these, also any pictures would be usefull.

thanks again Mark

See the other thread on this..

I have seen this, was thinking of Jenvey type not bike TB's

I'd see Steve Heath's opinion on this, he has them on the monster wedge's 5.2 L engine.

They are usually associated with lary race engines with massively ported heads and long cams. I don't see anything to stop you putting them on more mundane engines other than the cost - what spec is the rest of the engine going to be?

Hi

Hi Peter, have my Autronic ECU, V8D stage III heads, 'stealth'cam, de-cat, larger injectors

If you're planning to use the std 48IDA weber downdraught manifold then you'll need some extra bonnet clearance, there are manifolds which are a 'swan neck' type which curve back over the rocker covers to keep the installtion lower or the best solution which would be a x-over type to give the best run to the ports. Sadly I haven't seen any of these for a Rover which is why I started making my own and then cunningly sold the wedge.....

Hmm Matt how far did you get?

[350matt]

Well I got as far as slicing most of an existing injection manifold out, sealing up the back of the water jacket ( so I could use the existing water pipes & thermostat) and then making up all the pipes and welding them to the flanges.
I was intending to make a pair of plenums and feed these from the front by a pair of throtttle bodies. It would look roughly like a ferrari 355 set-up

I've got the 2 throttle bodies ( off a renault 3.0V6) and was going to mount the injectors about halfway up the pipes to allow some sequential injection to do its stuff. I've also got 4 trumpets to go inside one of the plenums.

Might get round to finishing it one day. As I've now sold my Rover V8 engined car I've kind of lost impetus as you can imagine

Matt sounds very intersting do you have any pictures, how far off are you finishing (time, money wise?)

How about these babies Mark,custom made 8x63mm,going in the racer,should suck more than a school girl on heat.









Sadly not on a RV8

ps:that's not the engine they'll be going on

[markh]

Thats just filth.........total porn as a matter of interest what make are they?

They are custom cast alloy manifolds,custom cnc made t'bs with Kinsler linkages,i'm making a filter/airbox for them at the mo.

I'll bung some piccies up once my girl returns for the weekend with her camera, but its probably amount another 150 quids worth of fabrication required to make the plenum chambers , machine the mounting faces flat and get some injector bosses turned up and then welded in
