440 bhp rover v8 anyone??

[v8 racing]

Any of you petrol heads out there fancy taking my personal race engine of my hands, would certainly embaress a few cerbies in your griff on a track day!!
Downside cost is HOW MUCH!!! £10,000 ps if apache is reading this i havent had much feed back at work and just curious how the motors running??

[v8 racing]

It's a 4.7 all steel bottom end with carillo rods omega pistons, wildcat heads done to my spec, cam done to my spec, modified 50mm dellortoes, msd ignition, crane pro roller rockers, titan oil pump, ally flywheel and twin plate ap clutch, grp a sump, electric water pump, billet race distributor, peak power was 438bhp at 7600 rpm and it sounded the dogs b******* at that!!

Thanks for the compliments guys, apache i would safely say 6750 i have never seen a tvr rod snap although the cranks twitch at 7k and above!! as for the cost of my motor i have bills in excess of 15k and a wife that ran off when she saw them!! to duplicate it around 12/13 cheap as chips then!! and as for the challenge steve!!!! nice figures by the way mate, how do you fancy a run down the strip?? although my engine will be strapped to a go kart chassis for less weight!!!! whats your engine in?? i did a turbo engine for a mate with after market heads in bmw i dont know the actual figures be nice too though

The terminal speed speaks for itself, certainly shows you have the grunt there, a mate with an sdi rover with 330 bhp was running 13.5 and he suffering from loss of traction, so i lowered his propshaft fro him on the cross member and he instantly hit a 12.7 with virtualy no wheel spin at all, be nice to see your motor down the strip when your next there? i will challenge you to my bike!!

Nice one boosted! totaly with you on blowing the rover engine they just seem to love it!! a customer who has a 5.3 is gagging to let me twin turbo his just to get around his wife somehow!!

That takes me back a bit i remember rebuilding the engine in the minor after nick sold it to bill, i never drove it when nick owned the car but bill took me for a spin in it but by now it was taken out to 4.5 with gas as well and to say it was quick was an understatement!!

Physical witnessed my 4.7 i have seen 8600
My old 3.9 which was on flapper with 2 air flow meters was 7800
Not witnessed i have heard of a destroked 3.5 down to 3 litre that revved to 10,000 but true or false who knows??

ok i had a chat with mystic meg to what the question was so here is some figures and rpm limits!! these are engines i have built and witnessed on independent dynos so obviously there are also more powerful ones out there i havent,
3.5 311 bhp @ 6900 dd carbs
3.9 342 bhp @ 6700 twin plen 2 air flow meters (adams)
4.5 368 bhp @ 6900 dd carbs
4.7 448 bhp @ 7800 dd carbs wild cat heads
5.0 388 bhp @ 6500 dd carbs
5.2 417 ftlb 4000 388 bhp at 6100 built for torque! dd motec injection welded and reshaped heads
turbo section
3.9 450 ftlb @ 3600 370 bhp at 5500 hotwire (adams)
5.0 803 ftlb @ 4100 714 bhp at 6700 throttle bodies home made ecu software wildcat heads
Run of the mill
4.0 griff etc 250 bhp 5500
4.6 griff etc 280 bhp 5500

Trying to answer as many questions as i can i will start with harrys good question! The main reason most of them are on dd carbs is because they were all race engines so power is the main aim and the only injection good enough to match the power outputs from carbs when i built these was a motec system which cost over £4500 carbs £1500, the reason the griff engines dont give realy high outputs is for several reasons i cant/wont say to much here as it would be degrading work that people have done but lets just say the wedgies dont suffer as bad!!!
The running of the two flapper air flow meters was easy for me i just watched mr adams do it!!
The driveabity of these "speicial" engines on the carbs was reasonable if you asked it too pull from 1500 rpm they would hesitate but gradualy pick up, the injected one was a nightmare flooded on start up etc... i had to fit a switch so i could crank the engine and while cranking then fire the injectors! so absolutely no good as road going engines.

In response to dax, it depends how much you have lowered the compresion by? at 9.75 with 8psi you are going to be running some pretty high cylinder pressures there! with that you should be up around the 350 to 400 ftib mark so i would keep the revs well below 6000, maybe boosted or stevie turbo can help me on this one they seem to be the turbo boys

[v8 racing]

I should think you do!! never realy been one for blowers myself but slowly being converted!!
