Interesting summary. Would like to hear more. Lot's more please.
Can we still believe that the Le Mans Triumph TR7 Rover 3.619L V8 achieved over 500bhp with twin 2in SUs coupled with twin turbos. 30 years ago! If the same was done today, our 5L would/may be capable of nearly 700bhp. Strewth! If this is possible, then the LS3 need not be an option. Lot more life in RV8.
personally no i dont think it made 500hp, maybe 350-400hp, 700hp is easily achevible with a pair of blowers if the engine is built to suit and runs a good management systemCan we still believe that the Le Mans Triumph TR7 Rover 3.619L V8 achieved over 500bhp with twin 2in SUs coupled with twin turbos. 30 years ago!

Rob,
Good post.
Anything special for the 4.2 (mine) and 4.5 SEAC engines power wise?
Several times I've read that the earlier engines churned out more horses. These were homologated for racing if that makes any difference?
I know there are both long and short stroke 5.0's.
Is one an aftermarket combo or were both fitted into various TVR's?
Is there much difference in revability between the two?

A big thank you Rob - I think that's the most instructive post that I have seen on Pistonheads in a few years now.
It certainly contains some not-seen-before gems, and actually solves a mystery that I have been trying to investigate for a while now.
Thanks for taking the time out to post that.

Really helpful, thanks. If you are going to tune a RV8 in stages would it be a good idea to start by fitting a modern engine management system first? I am not sure that the TVR Power MBE system at £3,000 in VAT fitted, would give you the best bang for your buck, but could a good system give you more real world power than head work for example on a 4 litre?
management systems will be covered too, v8 racing said:

The Le Mans TR7 RV8 did 201mph down the Mulsanne. Only Brummme's TVR LS3 has done 202mph. In due course would like your idea on how to build an RV8 to get 700bhp. Even 500 would be plenty. Suggestions for camshaft, blowers, managemnt, cooling etc. Thanks.
