Has anyone out there fitted a nitrus kit to a tvr ? do you have any comments on the subject, it seems a sensible way of getting huge power just when you need it !! as long as you are going in a straight line at the time.
I'm not saying my chim is slow but it could make things more interesting.
You know it always used to amaze me to see cars like Fiestas souped up to the nines, and I wondered why people didn't just spend all that extra cash on a better/faster car to begin with.
I really hadn't expected someone to do the same to a *real* car. Do you have the 5 litre version? If not, wouldn't that be sensible.
I have to say I'm not sure the block would take nitrous to any real degree, and it's a very tricky thing to get right. Bear in mind this engine is already heavily tuned and mod-ed from Rover's original, that might just push an already highly strung engine over the edge.
Good luck though if you do try. Let us know (I know I know, but if you're *going* to do it, we might as well hear what the results are :-) )
Richard Thorpe at Wedge Automotive fitted a Nitrous kit to his Griff 500. Apparently it was quite impressive.
But buying Nitrous refills can get very expensive and of course you won't be able to use it for any motorsport.

Quite a few work mates have done this to there shopping car(t)s (Ford Ka, Astra GTE, and a 535i) quite impressive in a straight line, the Astra can keep up with my Chimaera, but only for a short period of time, and it's expensive. A smallish bottle of gas, 6 minutes worth will set you back £40 and it makes super unleaded seem easy to get hold of. All the cars above have broke something at sometime because of the extra power, usually inlet manifolds, and airboxes, but don't let me put you off, go for it, and let us all know how fast you go before it all goes bang!
Having used Nitrous myself successfully(non TVR but same principles), I can say that pound for pound it is THE least expensive way of adding power. That said a small dose on say 50(bhp) jets will not bring any harm as long as the additional fuel requirements are met. Its when people get greedy and want more, without balancing the additional fuel and the ignition retard requirements that problems start (got to keep that 14 to 1 balance). Its only adding more cool oxygen to the "burn" which is what a forced (turbo/supercharged) induced engine manages mile after mile. Think along those lines and your not far off the pace. Obviously a compression ratio drop is wise if wanting more horsepower/torque, thats where the real expense lays. Try Highpowered Nitrous systems in Doncaster for more information. The real draw back I found was getting the bottle filled and fitting "hotter" plugs for the higher combustion temps(I was adding 150jets though!)
