Hi
Im new to this forum.
With my Spitfire I found many sites, mainly in America, for adding more power to the stock Triumph engine. For example www.prirace.com offer everything you could want in engine tuning, my own Spitfire is Supercharged.
In regards to the Stag though the best I can find is a Holly carb conversion giving me around 165Bhp.
Assuming overheating is no problem can any one give me advise as to how I can get the maxium power from the Stag V8?
Looking at the space available around the engine it seems forced air, preferably turbocharging, is going to be difficult. Does anyone know if it has been attempted in the past?
Many Thanks
Colin |

| try hart racing i think he got around 200 bhp in his racer. Turbocharging a stag engine would be a no no i dont think it could get rid of the heat. The only option for a big power stag is an engine swop rover chevy small block ford windsor all good for 300 or if ur really brave a YB cosworth an easy 400 bhp+ |

| An engine swap is a no no. Got to be the Triumph V8. |

Colin if you want real power with reliability forget the tv8. Yes t hart achieved good power increases, but at what cost?
Heres my car at lemans we come in about 30 sec, turn the volume up and enjoy. http://uk.youtube.com/watch?v=NoDEeRmDu2M

The triumph v8 is a more modern engine, well it was back in 1970. As it was never used in any other car other than the stag it show what a crap engine it was. The rover on the other hand was used by load of different companies right up yo a few years ago. That must say a lot. It was even used for the Metro 6R4 rally car, even though they did lop 2 clyinders off so it was a v6 so it would fit.
Get a 3.9 injected one and have some fun. Even in standard form it gives just under 200 bhp. If you want more its there, just modify as you go along, a bit here and there.

Interesting post. With a car like a Stag I am not sure making it into something really quick is what they are all about.
Mine has a RV8 with Holley so, in theory, I could get more horses from it but I am not that interested. If I want performance I use my M3  |

One of the best things is to fit tubular exhaust manifolds. Also the Holley is not working to full capacity unless you have a modified inlet manifold; the standard 4-into-2 is restrictive. (better still convert to a really good fuel injection). Then get your ignition system properly set up; you need plenty of advance coming in at higher revs but watch out for pinking. Is your valve timing spot on? There is not much other standard kit around for tuning though. Higher compression pistons are available but v.expensive.
