Individual Throttle Bodied TVR 5.0L with Megasquirt
Discussion
Cheers Jooles.
The plumbing down the middle is a tapping from each throttle to give me a MAP reading for the ECU, I want to try to run this in speed density mode rather than Alpha_n if I can as I prefer that, it will also feed the fuel pressure regulator when I get it all plumbed in,

Hi,
the throttles are from a 2002 Suzuki GSXR600, they are 38mm internal diameter. The injectors Ive replaced with 310cc/min, but the originals would have done ok as they were 250 I think, but as I already had a set of 310's I used them. The manifolds I made from a sheet of ally and some ally tube a mate gave me, the tube was simply squashed in the vice to give it a oblong end to match the intake holes of the head, the whole lot was then welded up and dremmeled out and polished so it looks and fitted ok. I cheated by using 45deg Samco hose bends to get them upright, it seemed the easiest thing to do and looks pretty good. The remote thermostat came from Reel Steel, £55,

I did ring Samco up and ask them about them collapsing and they assured me they would be OK, but they arnt actually very long, the middle ones are cut in 2 and have an ally tube in them to get them to turn into the throttles for spacing reasons so they cant collapse at all and the outer 2 I can squeeze them but they dont shut as they arnt long enough if you see what i mean, but I guess I will soon find out

Worth keeping an eye on, hoses that are collapsing round the end of a spigot suffer very high stresses and may eventually begin to tear. I'm sure you can imagine what happens next. If they do deflect significantly you might consider putting a spring inside. I'm sure it will be OK for a while anyway.
The servo is connected to cylinder 4, the middle cylinders are connected as the pipes were welded together first, as to weld in the middle was impossible, so theres a hair line gap between them so they will interconnect. I dont see why it wont work like that, it should be as good as before.
If you need an ECU to control this sort of setup give me a shout as I sell MS's, I will be putting a description on my new site when I get the chance, www.extraefi.co.uk

:rubs hands together in glee: yes please, but I really do need sequential. Just wish B&G would hurry up with that router board!
