Nitrous Mondial/308qv

I am new to this site and dont know if this has been posted before, but is there anybody out there who has used nitrous on a 308qv or mondial 3.0qv, I know there are a lot of purists and people who refer to this as cheating but I know you can get good gains from it, I know all the principles and fitting it, but I have never met anyone who has fitted one to an older mondial qv, I have seen a very quick 348 which was a lot faster than me in a 355 on the straights on a trackday last year, I have a good strong 308qv engine with 41k on it so I know it will be ok, I just don't know what a safe bhp jet to use, anyone out there who can help please,

 

Hi Snj5, Thanks for the info, the st corsa nitrous kit is fitted to a mondial t the same as the 348 I was originally mentioning, it also doesn't explain what jetting is used

 

Hi Mark 328, I know what you are saying about blowing up engines but nitrous is a bit like alcohol, if you drink too much you will fall over, and if you put too much nitrous in an engine it falls to bits, if boy racers can stick it on 1.6 engines safely upto 60-75hp, then 50hp should be a good starting point on a 3.0 v8 engine, I have a progressive controller which is designed to eliminate wheelspin on drag racing where it injects it in in small amounts then larger and larger, this is also good for putting less strain on the engine, the only other major problem there is is that if the nitrous is still injecting when the rev limiter cuts in the nitrous will cause detonation, which can hole a piston, I have a Msd digital window switch to cut out the nitrous at 200rpm prior to the rev limiter cutting in, as I said I know I am fairly safe with 50hp, I just wondered if anyone has gone as far as 100hp safely, obviously the age of the engine is my main concern

 

Hi, I use a 355 a lot and when I get in this it seems slow, but I still love this car and would never part with it, I do a lot of trackdays and intend to do some 'run what you brung' events, I will fill in the profile shortly

 

Hi, I prefer the Nitrous express, I have almost a complete set up with a carbon fibre bottle, I had a wizards of nos kit on a drag bike and I wasn't that impressed by the quality, nylon high pressure lines etc..., you weren't at snetterton last july on the foc trackday, I have emailed nitrous express and when they reply I will post it here if anyone else is interested in fitting a kit and need to know the safe jetting

 

Hi,
Firstly, I got an email back from nitrous express and it as follows:''I would recommend not going any higher than 100hp. It should handle 75hp easily though''.
So with this in mind I will play with 50-60hp using the progressive controller, then slowly raise it from there.

On the foc trackdays here in the uk you go in classes, I normally use a 355, but I really want to use the mondial, I have stripped it out for weight loss, and I will only use the nitrous occasionally on a straight if there are a few 'equally matched' cars in front, just to blast past, I'm not sure how long the bottle will last, the carbon fibre bottles are 12lbs, so it should last the whole day (hopefully), I will keep you posted of my progress and would still like to hear from others experiences using this on a 308qv engine

 

Intreresting, which car do you have that fitted to

 

What size engine do you use 100hp on
