very interesting site that!
Im getting there!
Ive made up a piece of 80mmx80mmx3mm thick boxsection,cut it 11 inches long,with an angle on one end to give the throttle body clearance to connect the water hoses,ive welded both ends up,im goin to vaux tomorrow to get a lower inlet manifold gasket and a throttle body gasket so i can cut the holes for lower inlet and throttlebody.then ill have to mount several hose connections for the brake vacum connection and other vac connections.
Heres a little top veiw sketch of my box.
The vac connections will go on the right hand side some where.
And the lower inlet holes and mount points will go on the bottom.
What do ya rekon?
Ive done the throttle cable bracket and the bearing bracket,i just have to mount the throttle body and inlet holes and mount points.
To mount it im gonna drill the lower inlet manifold threads out,drill and tap the bottom of my box and screw the box to lower inlet from underneath,or id have to use long bolts from the top going through the box.
Should be complete soon,ill just have to put it on then and get on the rollers.
Cant wait,i hope it works out ok!!!
Could you make a second box for me?What is the internal volume of the box, and how did you relate it to current items on the market?? Don't really matter that the box has the throttle body at an angle looks like it will cause friction in the throttle cable and give you issues??
it wont cause friction as ive put a wheel with a bearing in on a bracket so the cable corners perfectly smooth.
I was just looking at that other site you said.
It shows little trumpets mounted inside the box to guide air into the lower inlet runners.
When iv got it up and running ill do ya one if ya want,if its any good that is.
It has to be better than standard,and i rekon you wont lose much low torque as you are retaining the origional lower inlet manifold which is quite long,which is good for torque.
Ive finished making my inlet box now and im just waiting for a gasket to come in at the vaux dealers.
If i get the gasket before this weekend,ill be having a go at fitting it this weekend.
I took the upper inlet and throttle body off a few weekends ago just to get an idea of how things fit.
Its looking pretty good actually,ill let you all know how i go on and what kind of difference it makes.
Any more ideas or comments before i fit it?
Ill try and take some pics of it before i fit it so you can see it from all angles.
If it works ok im gonna get it powder coated so it doesnt go rusty as its mild steel,we didnt have any stainless at the time.
That is wicked let me know. I'm considering the same now, but thinking of trumpeting the inside, cause it aids airflow lots, to try a boost the power as much as possible. Also read that the plenium volume should be approx. 2x the engine capacity i.e 1.4= 2800cc plenium. And if it's larger then you loose throttle response, but better high end power and vice versa if it's smaller.
The external dimensions are 80mm x 80mm x 300mm
8x8x30=1920cc,going on your theory its a tad small,but this may be ideally suited to road use.
The 80x80 box section i used is 4mm thick so i will be slightly smaller than 1920cc.
Ive ordered a curved mill bit so i can radius the inlets inside the box instead of trumpets,was going to fit it as it is for now though just to give it a trial run.
Ill try and borrow a digicam to get some pics of it.
I agree with everything MC says, you might think I always post whenever Velos is mentioned, but if you have work done by them youll realise how enthusiastic and knowledgeable they are, and if you have experienced work carried out by other companies like I have you want to tell everone else what they are missing out on. J1400 If your considering a turbo 1600 16v as they are developing one with an expected 300bhp. Speak to them for advice which they are happy to give.
