Forced induction: yes or no?
Discussion
The hours on my SR3 with a 1500 motor are heading towards 50. The engine is still very strong but I am planning ahead. Once a rebuild is necessary I was thinking about turbo charging. I only know of 1300 engines being turbo charged and I am not sure if it is advisable to do the same to a 1500 engine.
I loved the reliability of my engine and I am a little worried if turbo charging would make me spend endless hours in the workshop. I see a lot of other turbo charged cars (not Radicals) constantly breaking down during sprint days.
What kits should I look at? Stage I or II? Do I need to upgrade my clutch and gear box? Are any other upgrades advisable?
Any feedback or advise from anybody who has charged their engines would be appreciated.

I've considered it once or twice, but the above pretty much tallies with my desires and what I've seen. I only know one person who's not had trouble with his turbo setup and that runs at ~375bhp day in and day out. I've seen a good few gearbox and engine internals from the others.andylaurence said:

Do you know who that person is to get some advise?I am happy to spend the exta money to strengthen key components to make sure the set up is reliable.
I'm running a 1500 SR3 turbo this year in the British Sprint Championship. The car was turbocharged some years ago and prior to my purchase in January was a succesfult hillclimb and sprint car in Ireland. However it had some turbo reliability problems mainly due to a poorly designed exhaust manifold. The engine / gearbox unit itself wasn't a problem to my knowledge.
Simon Tilling advised me to speak to Chris Tullet Exhausts, who built be a manifold and part exhaust system which is reputed not only to solve the problem but also vastly improve flow and therefore output.
It's early days yet, but the car is producing competitive times on low boost, with a lovely flat torque curve from 5000 to 1000 rpm.

By chance was reading Evo mag, an article on Geoff Page the engine builder and he mentions the Mussett MR-1500T http://mussett-racing.com/ that he is working on. The specific engine mentioned seems to be £32.5k + VAT!
Might be worth a call (or might not). Or perhaps Geoff Page himself http://www.geoffpageracing.com/

Quite a few turbo busa's appearing on the National hill climbs this year, all showing amazing speed through the traps.
One of the sports racer style Force cars has gone from a finish line speed at Shelsley of 107mph with a full house 1585cc Busa to 131 mph with a 1.3 turbo.
Amazingly that speed was achieved after being de-tuned to be on the safe side (as its a new build & at the start of the development curve) doing that speed on every run as it was out of gearing before the line!
