Codeblue Posted July 5, 2018 Share Posted July 5, 2018 (edited) Doing a few performance upgrades. A t3/t4 turbocharger is being fitted to the exhaust manifold. Original exhaust outlet will be used. Upgrading the oil filter housing to a modern unit that can have an oil output to lube the turbo and use a standard auto canister filter. 6-8psi of boost should boost power by about 30%. It will boost at low rpm so it wont have turbo lag and will basically behave more like a 6litre engine instead of a 4l. I means ill be able to go up reasonable hills at reasonable speed without dropping down gears. Ill be installing a good heatsheild for the dizzy. As per a helpful ferreters suggestion, i may upgrade the head bolts and gasket. I realize there is a risk i might break something but i have spares for everything and its only money and i can always earn more haha For brakes i have added a vacuum booster where the old air filter used to be, and remade all the lines. It pulls up super quick with only gentle pressure on the pedal, so much nicer to drive! Because of the turbo the manifold won't have vacuum so ive added an electric vacuum pump with a pressure switch to maintain a constant vacuum.

Ex-boy Posted July 6, 2018 Share Posted July 6, 2018 I'm sure the purists will have looked anyway and been scandalised but I think ferrets are common enough to have a few extra 'variants' without being an issue and it can all be returned to original later if required. So good on you for showing what the army missed out on for all those years. Steve. 1 Quote Link to comment Share on other sites More sharing options...
Tony B Posted July 7, 2018 Share Posted July 7, 2018 (edited) Uprated brakes, so much safer to drive. Especially with the Mobile Muppets you get now a days. Head in mobile brain in neuteral. Wise move. What's with the vacum pump? Would be a very useful gadget on my Katy's wipers. Edited July 7, 2018 by Tony B Quote Link to comment Share on other sites More sharing options...
albertamj Posted July 7, 2018 Share Posted July 7, 2018 Whoa! (That's North American for holy crap!). We need some video of this modification in action and some performance updates ... And I thought that I was pushing the boundaries with electronic ignition and fuel pump. Darcy Quote Link to comment Share on other sites More sharing options...
Starfire Posted July 9, 2018 Share Posted July 9, 2018 I think that my Ferret has pretty much enough power (although it can be a bit of a slug up steep hills) and the power brakes would be nice, but I always thought that the Saracen would benefit most from a smallish turbo - I've been in situations where that thing is going flat out in third gear up a hill, at 15 MPH! It sounded awesome, but it was way too slow, a bit of boost would have woken her right up, and being a slow revving, low compression engine, I don't think that an extra 30-50hp would hurt anything, especially if you weren't thrashing it all the time.

terryb Posted July 9, 2018 Share Posted July 9, 2018 holy sh#*-new wheels, softer shocks, and a V8-what a difference! I think ferrets just shot up in value............ Quote Link to comment Share on other sites More sharing options...
Codeblue Posted July 9, 2018 Author Share Posted July 9, 2018 Yeah except they blew 2 gearboxs and a few bevel boxes trying to film the toyo commercial. Not to mention the engine is exposed on top and they replaced parts with aluminum. Im in the process of making my second ferret better than the toyo ferret. 500hp, no gearbox bevels or hu gears. And an unchanged hull. Quote Link to comment Share on other sites More sharing options...

Yeah, but it wouldn't be the most fun I won't actually modify the Saracen, hanging around at a museum has me wanting to keep all of my vehicles stock for some reason.

I assume, that you are also confident that the cooling system can cope with the extra heat. Quote Link to comment Share on other sites More sharing options...

patracy Posted September 18, 2019 Share Posted September 18, 2019 Mind sharing a few more details? What specific turbo is that? How did you plumb the oil supply and return lines? What carb is that? Quote Link to comment Share on other sites More sharing options...

The reason that military engines are detuned is simple, the lower the power output the less stress on the engine components therefore the engine lasts longer. 1 Quote Link to comment Share on other sites More sharing options...
Lynx22B Posted September 18, 2019 Share Posted September 18, 2019 If I was still crewing those for a living, it would be great to have a Squadron of those, almost a logical evolution, High speed reduce. Just have to keep the rev's down so you wouldn't be heard by the enemy. Quote Link to comment Share on other sites More sharing options...
