Why not NOS? - 986 Forum - The Community for Porsche Boxster & Cayman Owners

A buddy of mine just got a custom nitrous system for his 70ish Buick Skylark GS. He said "I bet you could get your Boxster sprayed for about $500" which piqued my curiosity. I searched this forum and found a thread from about 3 years ago where someone said Toolpants had sent him a pic of a Box with a nitrous tank in the trunk, but no technical details. Obviously, nitrous is not something you need in the twisties, and okay, it does seem a little juvenile on a car like the Box, but for cheap, straight line horsepower, why not? Is it doable, or is there something about the engine that makes it a nonstarter?

No it's plain dumb.

Hey, thanks. That's just the kind of insightful, technically competent and thorough explanation I was seeking.

I don't think I'd do it to my boxster because it could blow the engine.

It could blow any engine in any car, but replacing the motor might cost $2k or less for a rebuilt one... whereas a rebuilt boxster engine is $7k plus installation, right?

It seems to come down to risk.

I do wish someone would do it though.... and it should be YOU.

Get busy and come back to this thread with pix and video of it in action. We have a need for speed! :dance:

I will be working on it within the next month or so

And that's why I fully support your decision to do it. Ha!

I too have always wondered about juicing a Boxster. Most people, I find, have little to no experience with Nitrous. That's why you hear cries of caution when approaching the idea. They don't know much about it or have had little experience with it. (People fear what they don't know -who said that, Batman?)

In my several years of participating on this forum, I have never come across an individual who has juiced their Boxster. You'd be a pioneer!

I think it's something I would do to mine. I'd go SMALL though, nothing more than a 50 shot. I don't think I'd trust a $500 job though. I'd track down a Nitrous expert and some one that knows Porsches. Ask the right people the right question.

Anyway, go for it and post your results. You shall be the 986forum guinea pig!

"I don't think I'd do it to my boxster because it could blow the engine."

But WHY could it blow the engine? What does that mean? The crux of my original post was, what are the technical limitations of the engine, what would the failure mechanism be?

Sorry Jeph, I haven't bought into this idea yet-I just said my curiosity was piqued. After all, Boxster drivers typically say that on the track they can carry equal or better speed through the corners compared to 911s, but they lose time in the straightaways, which is where the juice could be used.

But would it be practical to use NOS on a track when you're doing multiple laps? I thought NOS was more for single sprint runs for 1/4 mile races and such.

In the early days of being "on the bottle", novice individuals gave the concept a black eye by not properly metering the squirt. To much gas tends to get a little to hot and things that are suppose to move will become welded together.

Current systems are pretty much full proof. They come with jets that meter the correct amount of fuel and fog and solenoids that will shut down if pressures aren't enough. I wouldn't worry much about blowing the motor, then again I wouldn't go putting in a 300 shot and expect my bottom end to hold together unless I strengthen it. Any car should be safe up to a 150 squeeze.

That Tool Pants and his pictures....

After recently cutting a stock Boxster piston in half to do a cross sectional study on it, I'd say it would not be very kind at all to the cylinder pressure increases associated with fogging the engine...

Turboing the Boxster is certainly the best all around way to gain performance.. The Turbo specific engine combination we are developing now, coupled to the cylinder upgrades is sure to make serious power, reliably.

^Now there's some sound advice!

I read the post over at 6speed about a Cayman S that gets turbo'd by Evolution Motorsports making 400+rwhp and the engine still has stock internals...

I'm sure it'll be fun while it lasts but the guy's basically driving a ticking time bomb.

RandallNeighbour · 08-25-2008, 10:32 AM

Jake, please develop and sell a 3.4 turbocharged motor for the boxster with all the cylinder sleeves and other great parts I just saw on your web site.

I'm betting you'd sell enough of these now that cars like mine are 12 years old and on the second motor. I won't replace my motor again with a 2.5, that's for sure. I'm going for wicked-fast next time around.
