supercharged SC on nitrous
 

l was in Vancouver recently and saw an SC running a Paxton with gas ! l`m trying to locate the pics.The car was in average condition and looked stock otherwise,the guy at the shop said it was fast....l missed out on a complete nitrous setup on Ebay last year,complete set up with all the cool stuff,remote bottle valve etc.l had a 75 2.7 on it`s way out and l thought l`d play play around before adding the chevy 350.The nitrous kit could be fitted to the V8 afterward...l know air cooled engines are a poor choice for nitrous conversions but does anyone have any experience with Porsches on NOSSS?

I think you meant to log on to the Camaro board.

Why not just start out with a 930, then boost from there?

Straight line speed and drag racing are fun until you grow up, or get bored with it. Some never do either. Porsches were meant for the track. The track addiction will keep even the worst A.D.D case entertained for a lifetime. I grew out of drag racing shortly after high school. 12 seconds of seat time or less, is pretty lame IMO.

glad to see you`re all growed up amigo,what did that take you you to post? 12 seconds ? pretty lame IMO. l was curious if anyone had information on the effects of nitrous on air cooled applications but thanks for sharing anyway.

Was this a black SC with a cork or tan interior?? If so I drove the car about 8 yrs ago, just after it was built. The shop that built it is now out of business..... go figure. It was damn fast. Like 993 TT fast!! Where is it now? It was a little, ummmm ...... well .... not quite a"mint" car back then if I recall correctly.

Cheers, Jeff

Tyson, I think the guy that had it built tracked it quite a bit. The story I got was that they put the nitrous in it only to cool the intake charge and that helped it make more power?!?!?!?! It had all the suspension work and big brakes if I remember correctly.

Jeff

that`s the car !! it was used mostly as an autocrosser/street rocket.l saw the car for the first time in 97 and it was in a showroom down by Granville island.At that time the guy on the floor at the shop said the gas was used to eliminate lag and l think he may have mentioned it helped cool in place of an intercooler..

Tyson, I respect you and have read a lot about your abilities as a track driver so why are you dissin' drag racers? It takes a lot of skill to be competative at drag racing. Besides unless you've driven a 10 second or faster car you don't know what you're talking about. Sure 14 seconds is boring, 12 is a little better but at 10 and under it's flat out awesome and difficult at the same time. It's like putting down Nascar drivers when they're probably some of the best in the world at going around corners (read: no driver aids like ABS etc) I prefer to respect all forms of motorsports, sorry.

As for nitrous on a aircooled engine, it could help act as a liquid intercooler in small amounts with a supercharger but I'd stay away from anything but a mild shot. Detonation and nitrous don't mix well and aircooled P-car heads don't have the heat capacity to handle a big shot, heck alot of cast iron watercooled heads aren't up to the task. A purpose built nitrous motor has custom pistons with thicker domes, aluminum heads with polished chambers and a cam profile ground to favor the exhaust side. A serious nitrous car will empty a bottle in one pass using a 2 or 3 stage timed fogger system.

Yep, that is the one. The shop was called German Motor Car. I bought my first 911 from them. Rick is still around here somewhere but he is a bit ummm... well I can't really say on a public forum!! The guy that had it built never ended up paying Rick in full for it so they were selling it to recuop some costs, or so the story goes.

Next time your comming up, let us now there is quite a few Pelican heads around here.

Jeff

I don’t think nitrous is such a bad thing on a 911. If you do it right and don’t cheap out I can’t see how a 60hp nitrous fogger kit could be any more detrimental to your engine then running a turbo that yields 60hp.

I’m running a 60hp fogger kit on my 3.0 with Webbers / headers
I wielded in a second male too the fuel tank for a fully independent fuel system for the nos kit. Auto-meter electronic fuel pressure monitor to monitor fuel pressure. Electronic nos kill switch if fuel pressure ever goes bellow 5 psi. Weber IDS carbs that are designed to run rich a full throttle. RPM chip to only allow nitrous flow from 3k-6k RPM. Crane came ignition with ignition retard for nos. And rev limiter set 500rpm above nos cut out.

If you got high compression a Nos / Propane system seems interesting as propane has a 104 octane rating but I still need to look into this some more.

hey Jeff,thanks amigo l`ll be sure to do that.l have a lot of family in Gibson`s,Vancouver,Victoria and l love to check out the ol' stompin grounds and of course go to Weissach to buy at least one RUF part,even if it`s only a shirt.l did drive my 84 911 up there once and what a great trip it was! Frostie !! that is an inspirational set up amigo,excellent work !!!!! lt seems like you`ve got the pro set up my friend,did you have other NOS experience before the 911 set up?

If the shop that built it was German MotorWerks (formerly located east of the Porsche dealer and almost under the Granville bridge), its no surprise they are now out of business ... they were among the most dishonest shysters I've ever met. They got me on a little insurance fraud scam, and still owe me a 944T motor (mine) and a few other parts they billed my insurer for but never installed. I can't say I was sorry to learn they are out of business the last time I passed through. Oh, and that story about recouping their costs ... I'd be a bit suspicious -- and check the serial numbers very closely.

Gibsons hey. We have a summer place just up the road in Sechelt. Right on the highway on the waters edge just as you leave town north bound.
Beautiful part of the world I must say!

Jeff

Paul. I stand corrected. German motorwerks it was.

Ralph is a good guy, but Rick hmmmmm.

Jeff

Different strokes I guess.

But nitrous on a 911? Come on. That's just silly. Who are you trying to impress? The only application I can think of is street racing, or drag racing. Both of which are just not Porsche's forte'.

Nitrous on an autocross or track car, well, that's pretty ridiculous. It's not allowed by any sanctioning bodies, and kind of undermines any sense of fairness. It's a cheat at best, and takes away from driver skill and vehicle set-up. I guess if you can't drive, you look for a cheat like this, but I don't get it.

Tyson,

I thought you have nitrous in your C2? :D :D

Building and then driving a reliable boosted/gassed car requires a great deal of skill and knowledge,just like an NA car but even more difficault.As for performance enhancements being "cheats" l don`t know anyone good enough to win with a totally stock car...unless that`s you?

Yeah, it takes a lot of skill to push a button.

Sure, it always takes mountains of skill to cheat. There are some really creative ways to hide nitrous. I could also club some guy over the head and take his girlfriend, but it would be a hollow victory. I spent X dollars at the speed shop, and pushed a button, and you didn't, so I win. Woo-hoo.

Bottom line for me is that nitrous is for street racers, drag racers, and HP junkies. I think it would be a lot of fun. Hey, I like the HP crack hit as much as the next guy. But I wouldn't do it in a Porsche since the crack hit for me comes in 135mph 4-wheel drifts rather than 3rd gear 120mph rear wheel smoke.

Frostie, nice setup although 60hp is considered a small shot in most circles. You have done your homework and set your system up right.

As for nitrous on a 911, no it doesn't make a lot of sense since drag racing isn't the car's forte (we do agree on that Tyson) but it doesn't mean it can't be done. It also doesn't mean a 911 can't be a contender on the dragstrip, take Juan's car for example. Nitrous isn't a cheat anymore than a supercharger or turbocharger is and in many way's it's more sensible if all you want is a quick blast from time to time. With nitrous you can get great gas mileage and great acceleration as well as engine longevity since the car is only "boosted" on demand and not all the time like turbos and blowers.

Let's face the facts though, would any of us complain if our cars could run a solid 10 in the 1/4 AND win on a road course? I think not! :D

Admit it, wouldn't it be nice to have the best of both worlds?

Different stokes for different folks
 

I guess I’ll go for the “120mph rear wheel smoke” over the out of control “135mph 4-wheel drift” :rolleyes:

Yes 60hp is a little modest, originally I was jetted for 90hp but decided to jet down to 60hp. The cars just for fun so no need to go with too much.

nitrous rocks and so does the quarter
