Stag Engine PI and manifolds

[stagdad]

Andy they are 2 sets of tr7 California spec manifolds that have been adapted to fit the v8.you can still get some if you search for long enough in fact I know of at least 3 single manifold that were for sale recently but they were asking big money.

One of the Locals here in Wellington has converted his stag to PI and I think he used a lot of Ford falcon componentry.  The work was done by a guy named dave who runs powerhaus here in Wellington (I imagine they have a website)  Powerhaus specialise in European cars and I believe dave owns a stag.

Just resurecting this thread. I'm wondering how the various EFI projects went, did anyone end up doing any manifold castings? Did the manifolds in Stagdads picture progress to a stage where they could be copied and cast?  Thanks.

I know Stagdad is making a new set of manifolds, I assume he found areas he could improve on.
I made my manifolds out of steel plate and tubing, in fact I have done three sets now for three different cars. The first two were more or less the same, the last one was built with a lot more care and developed on a home made flow bench.
With ported heads my own design of exhaust manifolds and Faversham Classics fast road cams I ended up with 246bhp @6650rpm and about 220lbft of torque.
Next project is another engine for my Stag powered TR250, I want to crack the 250bhp figure without lifting the rpm any higher. Don't think it is impossible as the 246bhp was done on regular unleaded so there is room for a bit more compression.

Got several other projects on the go, so it might be a year or so before I get it done.
