was flogging up and down the beach the other w/end while out on a camping trip, and towing the sand ski i made flicking it into the ocean (mega fun unless yo... Show moreu come off on the harder sand). the feroza spent about 1 hour at 4000rpm going back and forth up the beach in the soft sand. the engine never got hot at all, but when we got back to camp i popped the bonnet and found the under bonnet temps were extremly hot. the metal surround around the back of the headlight was too hot to touch, never lone the end of the pod filter!!
so i decided i will make myself a little extraction scoop/vent for the bonnet. when i turbo it there will be more heat so i might as well give it somewhere to go.
got out the trusty urethane foam that i made a lot of stuff for my Mr2 out of.
this stuff is great, just sand it to the desired shape with some 80 grit sandpaper.
then i layed fibreglass matt and resin over the foam once i shaped it (tried to keep it a simular shape to that of the hump in the bonnet).
once the glass went off i scraped the foam out from underneathe.
trimmed the excess matt from the edges.
well i got down the shed today and did some more work on the scoop. cut the vent hole in the bonnet.
cut on some glavanised tabs and fibreglassed them to the underside of the scoop, then i can put screws up from under the bonnet to hold the scoop in place.
sanding fibreglass isnt my favourite past time, even though i like to make fibreglass things. so i gave the scoop a quick sand and them layered some bog over it. much easier to sand to a smoothe finish.
once sanded i sprayed it with primer filler and sanded that smoothe ready to paint.
after preparing it with prepsol i painted it. found a can of paint at work that looked prity close by eye.
put it on and i am prity happy with the result. at least now i dont have to worry about heat being trapped in the engine bay. Show Less
i'm making a log manifold out of steam pipe (butt welds) for my turbo conversion. 35mm ID.
i'm not the best welder, been 3 years since i last made a ... Show moreturbo manifold. i get better with practise, just dont practise much. haha
the old arc welder i am useing is was my dad's dad's old Lincoln. it still works ok, the duty cycle is shitting itself though and sometimes blows holes in thinner metal.
i drilled out the stud pattern in some 10mm flat bar (used a manifold gasket as a template). die grinded out the port holes (still need to port match the head side).
welded the butt welds into a log.
i gave the log a good rogering with my grinder after i welded it altogther.
log and head flange ready to weld together.
then welded it to the head flange. like i said above, not the best welder. though sometimes it works really well. good thing i have my die grinder, i'll be able to neaten it all up. :-)
i've decided to use the spare T25 turbo i have. went down the shed on the w/end to do a little more welding. still need to clean a couple welds up and face the flanges so apart from that and some heat sheidling the manifold is done.
made the turbo flange ghetto style... ;-)
dropped the sump and welded on a 5/8" oil return.
turbo manifold trial mounted to the head and with turbo and oil lines trial mounted.
made the dump pipe from some mild steel plate and mild steel exhaust peices. heres a couple pics of it.
turbo outlet pipe from a thin peice of mild steel and an old i/c pipe i had made from exhaust pipe. Show Less
