Thanks for replies gentlemen.
I will go for the std setup as I don`t intend to bang a load of nitrous in.
Blowing through an SU carb is easy.Just reverse the spindle seals.fit a 40mm restrictor just in front of carb and boost reference the float chamber.
Finding the right needle and spring combo is the tricky part
I`m going to try one of those Aldon programmable ignition boxes that can retard timing under boost as using the distributor diaphragm is a bit on the crude side,even for me.

Thats pretty much how I figured out how to do it on a mates car with a blow though SU on his cobbled together turbo setup. It seemed to work ok until he fried it with nitrous though
Doubt I will be getting the m112 anywhere near 14000@ a 2:1 ratio.
I think 6000 engine rpm is the very most I will get and then not for too long if I want to keep it in one piece.
If engine does blow and performance was good it won`t be a lost cause as I don`t mind spending some money on a set up that works.

Ha Ha!!!
I've got the T Shirt on that one mate
I'm into my Rover V8 for way too much money now. But the results have been very good to say the least. Its a trap that lots of us low budget racers get stuck in. We cant afford huge chunks of money. But we can afford small spends over a long time to build and modify as funds are set aside.
If I knew what I was going to spend between 2008 and today on getting the Rover V8 to run mid 9's (and hopefully a high on the strip I would have taken out a loan to buy a new engine from the guy in the video I'm about to show you. This engine is for my mates Capri. Its over 1000hp on the carb only and it cost $12,000.00 + shipping. Work that out at todays exchange rates?? Luckily he has a mate who ships in from the USA regularly so he got the engine delivered to the UK for £400 all in. RESULT!!!
The engine in the vid arrived fully built and tuned to 1025hp minus the vac pump and the headers. Bloody good deal I reckon?
Having said all of the above I now know how to build a Rover V8 to make good power on boost and nitrous for drag racing. And it wont cost anywhere near as much as I have spent doing my own R&D in the last 6 years.
I now think I can take a stock 4.6 and add some new internals to my own specs and build a block and head setup that would make 500hp on boost and nitrous.
Remember that I said DRAG RACING, not road use
I only build my stuff for flat out racing these days

When I wanted more power in the dakar, I simply replaced the rover with a 5.7 chevy (Which cost me £400) and when i wanted more power, I dropped a pair of turbo's on the engine (£1000 for turbos + £1000 supporting parts)
So that's two power upgrades in 18 years of ownership. How many times have you seen people selling engines that have had a fortune spent on them in incremental upgrades?
I loved the little 1600 supercharged dutton I built and when I thought I `d got used to the power took it out in the rain for a laugh,I nearly poop myself a good few times and realised that i`m not the ace driver I had thought I was.
The TR with the v8 and 3.9 diff is just the same but the noise of a blower mixed with sound of the v8 has me hooked.
