Opinions on inlet manifold and fuel system

[MikeLMR]

March might be a bit soon I am planning to have the throttle bodies sorted and ready to go on by the end of the month (sh1t 10 days time !) then its off to Carl for an exhaust and then fitting it all to the car.

the major bits that could stop that at the moment are the bits coming from Aus and getting this stuff welded ... not somthing I can sort so its a yella pages job

[MikeLMR]

minor progress - found a vacuum fitting. End up using a 1/8th BSP Taper fitting in the 1/8th BSP parralel tapping so it seals without an o ring. Not bad for £2.50 hate to think what the same costs in bling bling aeroquip.

Also got the lathe in place and running, its in need of a good clean but we\'ve already cut metal on it and everything seems to work fine. Its a little worn but good enough for what we want.  (and I still ache from moving the heavy b\'stard on saturday!)

Hopefully going to have a word tommorow about getting the ally bits welded. (fingers crossed)

piccy of the fitting (yawn  )

been making the heat shield tonight ... its a new high tech material but we can\'t work out why the prototypes keep catching fire

Seriously the insulating mat should be here tommorow and then I can start cutting the ally sheet and folding it. Hopefully it\'ll fit once its on the engine but sods law says it won\'t oh well it can be modified if needs be.

fuel pump arrived today ... along with a load of other post I\'d been waiting ages for :rolleyes:

bling bling and its all out of site under the car !

[MikeLMR]

Adapters/flanges are being TIG welded today, picking them up tommorow I hope.

Been working in the warm on the insulation for the heat shield tonight. just need to cut the ally sheet and bend it suit now. Waiting till I get the flanges back to do that.

Also got some O ring gaskets for the manifold.

does anyone know what will happen to silicone hose when exposed to fuel vapour ? I\'m thinking not a lot but the hose companies are covering their asses. I have some 48mm ID samco stuff that I\'m thinking of using. The ends of the TB and tube will be butted up so its not going to see much fuel and its not exactly under a great pressure.

[MikeLMR]

Flanges and tubes are now welded

Will hopefully post some more progress pics tonight

edit - Damn they are difficult to photograph !

[MikeLMR]

bugger

got the holes drilled out for the mounting bolts no problems. Then decided to bore out the inner diameter to remove the step where the flange is welded on .... bad idea !

I had a few practice cuts on the lathe with some spare tubing and once I thought I had mastered the technique of getting a good finish I had a go with one of the adapters. Eeeek not a nice finish at all its all picked up and rutted then I managed to blow most of the fuses and burn out some of the cable to the motor while going for a higer rpm cut

hopefully I can get the guy who machined the flanges to have a go at sorting my mistakes ... oh well, I hope tommorow gets better !

Hey mike sorry to hear of your lathe problems. Alwasy takes time to figure out the quirks of a new(second hand) machine. Hope you gets it all sorted soon.

[MikeLMR]

thanks Mike, it certainly does take some getting used to

bit happier today, re-wired the lathe (just needed a plug) and swapped the carbide tip tool for a HSS boring bar which is more inline with the rpm the lathe can run at. (1500fpm surface speed for aly with a carbide tip! thats 2000rpm !) After some practice and some honing of the tip with an oil stone all went quite well and I even managed to clean up the cuts from yesterday and got a nice finish which I have now run some emery cloth through to take the polish off the surface.

a happy bunny today ... just 3 more to do ! at least I\'m learning

[MikeLMR]

Got the other three sorted today. They look really rough in the photos but are in fact very smooth with a cross hatch pattern from running some emery cloth through by hand.

[MikeLMR]

The lathe (still not had chance to clean it up)

[MikeLMR]

the work bench :rollin

what you can\'t see is the contents of 2 CVH engines spread over the proper work bench being rebuilt for a couple of weeks time.

Now Mike, I am starting to get more than a little bit of workshop envy!:D
 I was half way through a weld tonight in my emeregency workshop(i.e.  my bottom room of my flat!) and the electricity cut out. Apparently a telegraph pole self combusted. Hot metal, no lights and having to find the gas bottle without tripping up over the half chassis i was working on.
     And I dont got no lathe:(

  other than that , the electricity came back on about half hour ago.
 So when will the beast be running?

[MikeLMR]

I\'m envious too its a mates garage, not mine.  5mx5m square with a 25 foot ceiling ! (its an old chapel)

we had the same problem today, power was out for 3 hours + it surged when it came back on and killed my mates TV and DVD player electricity companies are no use either as three different companies supply the lines the power and somthing else they just blame each other constantly and nothing gets done. My mate is constantly left in the dark.

back on topic ...got the heatshield finished today and tapped all the ram pipe flanges ready to be bonded to the throttle bodies. think I have figured out a throttle cable fitting too, just need to measure up the rx7 cable to see what diamter it needs drilling out.

[MikeLMR]

crikey its been a while since I did anything on this.

I\'ll try and get an update soon. Last thing I managed to get done was fitting the ram pipes and fuel rail but then I got tied up with a rally and other stuff.  I also managed to make a backplate for my airfilter which doesn\'t fit over the ram pipes (should\'ve checked that one before cutting and filing all that sheet metal !) so it looks like I\'ll be running them with filter socks to start with.

Hopefully I can get the throttle bodies finished off this week as I\'m off work (famous last words .... just wait for the \'disaster report\' !)
