RV8 Tuscon Racers - how different?

[motul1974]

Just sitting at work contemplating yet another career change, when the idea of the old RV8 Tuscon race cars went through my head and I wondered how different their 4.5 ltr engines were to my chim 450...how did they produce 340bhp + from them, or was this just further massaging the power outputs as they did the road cars?

I don't think it was hugely difficult, everything is a compromise... you'd be sacrificing low speed drive-ability for top end power, It might go like stink on track where you're constantly keeping the engine within a high rev range, but it'd be a complete arse to drive on the road.. probably....

Just my opinion based on my limited knowledge and lack of understanding of most things

Can be done on a 4.5 not cheap though ........

That's a nice engine you have there.
Can you divulge the spec

Come to the next race meeting and walk around the pits for a close up view. Brands 1st May or 4th June

Yes a bit of massaging......different crank, rods, pistons and cam......and they went bang frequently !

Of course, there's a fair bit you can do modify a Chimaera for racing......

Wow, I knew you were doing a few mods Anthony but,,,,

I think those 4.5 engines were similar to the 450 SEAC build but with a race cam?

A very original & healthy RV8, front runner on carbs.................
