best carbs for sprint car
Discussion
a friend of mine is entering his car for various sprint events next year after trying it out for a few runs this year, the question is, which carbs should he fit for a 4.6 litre rover v8? he's currently got four 40s sidedraft webers, would 45s or 48s be better and if so which ones?
:confused:
Hi
I have to say that its not my car but it is a bit of a mix, its a lotus elan + 2 bodyshell on a TVR 350 chassis with the aforementioned V8, as far as i'm aware he's only been to a couple of tracks near York called Elvington there are two near each other i think, Any help would be gratefully received,
thanks

Carb size depends on the state of tune of the rest of the engine. Twin 40DCOE's would normaly be on the small side for a 2.3 litre engine, but then again the Rover isn't really a high revving engine, and if it's using the standard cams and heads then moving up to 45's may not gain very much.
Sounds eminently sensible. If I come across any articles on tuning that engine I'll post the link.
There must be loads of books on tuning the Rover V8. Such a popular unit.
Just checked and Demon Tweeks sell a book called "Tuning Rover V8 Engines" by David Hardcastle. It's bound to be decent. £17.99
You can't treat youself more than to buy a good (non-fiction) book I say!

Biggest is best?? you can tell your from the states!! Depends on the spec of the engine, these engines dont make very good bhp per litre figures in fact in normal stage 3/4 tune they are pretty sad!! a well put together 4.6 would only make 65 - 70 bhp per litre, 45's would easily cope with this kind of power, go too big all you end up doing is murdering the power curve.
