Thread: 3.9 v8 supercharged with NOS?help

Biggest problem was blowing tailshafts and diffs On 31in tires we dragged off a porsche to 80kmh, no more power needed so I would look at the blower and make sure it can provide enough air, the computer will definately need tuning as well. A piggy back computer would be your cheapest option. My current car runs the new wolf computer, but the standard one controls startup and low rpm. Makes 118kw at wheels with a 4.6 block and all drivability is maintained.

My old car had an autronic computer which was awesome however low speed work and cold starting was lost. made 140kw on 35's with a vortech v1 supercharger, but that was in a gq patrol so a bit irrelevant

Did he have it in low range when he blew the porsche off

Triumph Rover Spares have a 4.6 SC V8 for sale, i sent them an inquiry about it and a few other things, my spidey senses lol, are whispering that it will be big $$$ though.

They also do a few other rover motors that would probably be a better option than to SC a 3.9L on NOS, i think they do a pretty tough 5.0L and 5.5L.

Im, currently deciding on weather to build or buy a P38, either way a RR will be in the driveway soon

I think if your not using it for 4wding i would go for a rear mount turbo before i fitted NOS
Probably cheaper and easier and less likely to explode

Let me put my 2 cents worth in.I have a Rover SD1 with a high comp turbo charged 3.9 V8 from Triumph Rover spares.It was my everyday car for about 3 years.I never had any problems with it at all.Including driving in peak hour traffic on the Monash carpark.I had no intercooler and was running straight gas (LPG).I use to have detonation problems but since changing to a scorcher Distributor and having it tuned properly there were never any other problems.

It now runs 9 PSI and makes 300 HP.With enough torque to pull a house.All i can say is as long as the motor is in good condition and is set up right there is no reason why you cant make some good HP and be reliable.The only thing i was breaking was Rover diffs and the Rover 5spd gearbox.Which is now replaced with a Supra 5spd.

In the future i will be going Haltech E6S which i have sitting here and Haltech Distributor with a 3.9 plennum and intercooler.I would easily expect another 40-50 Hp gain.As for the Nos i cant help there.If you have it set up properly it should be fine.If your in Victoria and want to have a look at my set up your more then welcome.

Cheers

i kinda like the sound of their 500 hp donk. At 7K the price isnt too bad

yes that pic is my engine,and yes the supercharger is from a SUPRA

NOS isn't a fuel at all...

Correct If you don't add more fuel, it will use the pistons,valves etc as fuel
