Where are you going to put the throttle body and pipework?
It comes in perpendicular to to the engine, and with the TB and then a bend, its about 2 foot long, and thats without adding on 6" or so for the inlet manifold, whatever angle you point it at its going to go through either:
the subframe, the engine mount, the strut, the bonnet.
You could modify it to be side fed instead, but then that would TOTALLY negate the point of using it!
the problem with all the yb ones is that the air comes in from underneith which cant get to cylinders equaly and although much better the norwegian type comes in from the front witch means it has to cros the inlets of 3 cylinders before it gets to the 4th not ideal
the 200 one feeds all 4 equaly whitch is spot on but you would need to modify it to fit this is what i ment
the 200 one feeds all 4 equaly whitch is spot on but you would need to modify it to fit this is what i ment
It would be easier to fit the engine in the boot with a 200 inlet on it than it would be to fit it in the bay IMHO!

Sorry to hear about your problems Rod/Mark. 
Shit happens during development thats what happens when you try new things !
I am sure you will get it sorted.
P.S. That is one big jet engine LOL !!!!

good advice re checking the torque of the head studs,one very good tuner said to me with 7.9-1 and a T4 periodically check the torque of the studs due to the cylinder pressures.

10K+ Poster!!
This is something AVA always do on my engine and it originally alterted us to the problem with the mountune studs.

PassionFord Post Whore!!
yeah joe stevens from bluesprint motorsport is the man behind the manifold
(dont know why the others havent mentioned it)
hes been designing them for a while now and had the 1st one tested at harveys and said it produced some great results, especially with the distribution of the air to all 4 cylinders.
hes had a batch made up and sitting on the bench for a little while now but hasnt marketed them.
they have a round top part that bolts to the 4 trumpets, and there are 4 slots in the base looking at the road,
then theres a cone shaped part underneath that feeds the air from the throttle body which is infront of the std postioned one but at about the same height.
if that makes any sense, im doing this from memory, i dont have one to hand.
im sure some1 will post a pic or more details at some stage
i can get more info when i pick my engine up later in the week if people want?

Mark, its possible to still fit rings that need a lip in the liner, you just have to grind the liner instead of conventional machining it as it prevents the nikasil chipping i you do this.
Im informed Julian does this with the same liners as yours and coopers rings, he has been using cometic gaskets with the fire rings removed (special gasket) but is now going over to cheap payen ones apparently as it allows more clamping force to be put onto the rings themselves.
Cometic now do a new 7 layer gasket specifically aimed at very high horse power applications, and its a direct fit with no machining required.
If you are interested in trying them, Steve is confident he could get you a free one to try, as its interesting proof of concept for cometic for it to go on cars like yours. Let me know if you want more info.

Just spoke to Mark,
100% Gasket failure. nothing caused it other than a weak gasket. Mark was correct in using this gasket was a backwards step. He said gasket started to perish on pump fuel, so the race fuel figures were under what they could have been. Hardly any damage to the head at all. Head will go off to machine shop for a skim. No other damage so all is ok

At least there was no real damage caused.

Thank god for that !!
Good news !!
Jus hope you can find a gasket strong enough, before you run our of material on the head from all the skimming !! lol

Plus, the gasket yesterday was starting to perish on pump fuel which means the top end power runs 6.5k-8k may also be low. Im not sure how much difference it would make, but certainly the race fuel figures would be lower than what could have been achieved.

Happily retired
Well ive made the decisions on what we do.
The head needs a slim so another day is lost & so the car has withdrawn from Fighting Torque, im 63 not 33 & working 15hour days to get it to FT is not an option, so ive taken that decision now.
3 of the 4 gas rings had burst & the gasket badly damaged. Simon reported a slight 'puff' from the gasket on the pump run & thats probably why the 109ron only made 10bhp, the gasket was on its way out. The more efficient inlet added 40+ horses but finished the job off.
Have discussed with Mark what to do next & head gaskets/studs will be looked at, we simply did not have the time with FT on the agenda.
At Marks request will go to 8 injectors using the new inlet.

Getting the car to the event was always going to be a tall order considering how far back you started from. Didn't your competitor 
have a working and running car and fail to make it too...
imo you did pretty well developping and building the engine from scratch, new turbo, getting it all to fit in the car, getting the car ready again after a long time under cover, squeezing two dyno sessions in, in what is in all respect is not that much time at all.
Think you deserve a pat in the back, you've achieved more than anyone would have given you credit for, even if that's not the ultimate goal you were aiming for.
The dream is very much alive by the looks of things too
