Does anyone here know where I could get a nitrous oxcide kit for my BA XR8
I think its the way to go for bolt on instant HP
Also how big do you think I could go without doing any other mods to it?
Im thinking about a 150 HP kit

Read the current issue of street machine. it has a write up on cams that talks about Nitrous and the call one of the companies that sell it. Where you at.

Instant power yes, refils more regular than petrol if you a lead foot. (why i don't have it).
150hp would be absolute max on stock (IMHO)!

gotta be careful it wouldnt lean out with that much.... dnt know how much stock injectors can flow.... at the end of the day u would be better off with cam change and full exhaust... GT boys are gettin 350kw with exhaust amd computer change!

If the 5.4L is the same as the current 4.6L motors used in US then you will need a different nitrous system to suit your BA XR8 (not 100% I was told by someone).

In 1999, Ford redesigned the fuel system on the 4.6L motors by eliminating the return line from the car. They did this mainly because the new computer system no longer needed the excess fuel to be returned to the tank (for emissions reasons).
Since you don't have a return line to use to help boost fuel pressure when the nitrous is armed, you will need a nitrous system that is designed to be used on vehicles that don't have a return line on the fuel system. Nitrous Express has a kit that taps into the valve on the stock fuel rail (for extra fuel pressure) and is adjustable from 35 to 150 horsepower.

IMHO the only way I can see nitrous destroying an engine is if the motor hasn't been tuned corectly or if you are cheaping out on engine components but then again this also applies to turbos, superchargers and even N/A cars.

I thought Nitrous rooted your engine?
I have never heard of nitrous oxide ever killing an engine.:idk:

Too many ill-informed people make the presumption that because nitrous was experimental in the early days (60's and 70's), that it kills engines now.

Far out. If only I could count how many times, a turbo, blower, or even just a carby have 'rooted' an engine.

If nitrous is PROPERLY setup, I believe it CAN be one the safest major mods done to an engine.

Even today where kits are sold with nearly all the components to make a nitrous setup safe, and suppliers rant and rant about setting it up safe, I still see/hear of people taking shortcuts that will eventually cost them their engine or more.

To answer 330boss' query, If I was going to fit nitrous to a BA XR8, I would use a wet system, and I'd seriously consider using a progressive controller to get rid of that harshness, as well as research with anyone else that has done it, or ask the nitrous kit manufacturers, and possibly consider exhaust, timing, fuel and computer modifiactions.

150HP would be borderline if you were wanting to use it a lot, for a few years to come. If you've been in a nitrous powered car, you'll know that even 50HP is a lot in one burst.

The other thing to consider with a big shot like 150HP is driveline stress. Can it handle it?

At the end of all that, think about this, is it the person that holds the gun, or the gun that kills? :rant:

A 150hp shot of NOS would be way to much for a stock engine to handle in
one hit,a progresive feed system would be the way to go. I use 150hp hit on
my 351 clevo on the odd occasion and the kick up the arse is awsome, but
the enginge and driveline are built to take the extra load. A 10lb bottle
costs around $100.00 to fill and i only get around six passes on a full bottle,
so the cost may be worth considering. Another factor to consider would be
tyres, without full drag slicks a big shot of gas would probably cause serious
wheel spin. If you are serious about a nitrou setup give mike a call at MIKES

What bottom end/box/diff have you got to take the extra load of 150HP shot?

What times have you had on and off the bottle?

Thanks

While on the topic of N2O in late model cars, I have a EF Fairmont (6cyl, auto, with 150 000 km) with a few basic mods (extractors, exhaust, AU intake pipe and air intake) and have run a best time of 16.3 at 139 km/h. I will be shortly getting a higher stall convertor and XR diff ratio and would like to get around the mid to low 15's. Would a N2O kit get me there (with the driveline mods) and if so what size and type should I use (i was thinking of a 50hp kit). Sorry for all the questions but you guys really seem to have all the answers.

HSV.ETA:

With your planned mods and some n2o I'd think you'd possibly go beyond 'mid to low 15's'.

50HP would be ample.

As you say, consider driveline strength always.

And have the nitrous set up by someone that knows what they are doing.

Thanks for that info, what type of system would be most suited, i think a wet system was mentioned in the case of the BA XR8, would this type of system also be suited to my car. Will such a system effect my auto gearbox shifting? (sorry for the silly questions but I don't know much about N2O). What would a rough price be for a suitable system (there was a company install ZIEX (i think) set ups into four cylinders for around $1100, would it be a similar price for my six?

Go have a look at www.ozrace.com . With the OZNOZZLE you can up to 200hp out of one nozzle, all the prices are there. Have you thought about running a seperate fuel system for your nitrous, it would probably be cheaper than upgrading your EFI pump.
