What is the most HP you can squeeze out of an N/A 996?
I was just wondering who have the most HP out of a N/A 996 to the wheels? I am assuming it is hard to break the 300hp mark for the 3.4 liter engine.
The mods I know of so far are intake, exhaust, plenum, and a flash. Are there any other mods out there to bump the hp up a bit?

depends what lengths your are going to go to. I know the GT3 motor can produce about 600hp N/A. You will definitely have to modify internals, you cannot get it from what you have mentioned above alone.

or are you talking about some sort of race motor?

I wouldn’t be surprised if there are a few race teams out there with those kinds of numbers. They would probably limit that for reliability. I think on a street engine it would be an undertaking to get anything over 420. To achieve that you’re looking at running high compression and the highest end fuel all the time. To make any real big numbers your going to have to crack open the block. N/A power costs a lot more then turbo power since your only dealing with the 14.7 psi we breathe. Interesting question, but your better off learning how to drive faster or getting a turbo.

I know the $ to HP ratio is far from great with these cars but I just wanted to see what enthusiast have done to their cars for the streets. I want to bump my car up a few ponies just because I find it fun to work on my car.

HP's for n/a 996
There is not much you can do to increase the HP of these engines. The race engines in the GT cars have different cams, five valves per cylinder, increased size of intake plenum, throttle body, ported heads and larger headers. A totally different engine. To get real power, slap on a supercharger. for 10k, you can get approx 420 hp and have a real sleeper.
Good luck

this started off well, good question. i would like to see this thread stick to info on the 996 engine, not the gt3 which uses a totally different engine.
lets hear real n/a hp numbers from the 3.4 and 3.6 guys!

I would GUESS 320-340 wheel is definitely possible with the right mods...I just saw a boxter (986S) DYNO 221 with NOTHING done to it...and I would guess the 911 would dyno even better than that...
Honestly, FULL exhaust(headers, high flow cats(or bypass pipes), low restriction muffler, tune(many dont realize exactly HOW much this can affect a car) and cams could probably get you right around there...as far as speed is concerned though...if you really want loads, mess with some gears and a diff...a car with 300 wheel with the right drivetrain mods will ROAST a car with well over a 100 hp advantage over it assuming it hasnt been done up in the same way...

Whoever said learn how to drive faster hit it right. I was watching some autocross a couple weekends ago. It was pretty clear it wasn't the car but the driver who scored low times. My boss use to race formula cars. He said all the cars go fast, but races are won with brakes.

My comments were a bit off topic as they were based on the GT3 motor which is a GT1 derivative. The cars in the Rolex series are limited on HP (intake based) to keep them competitive with the Ponitacs, RX-8, etc.
Luis Aldaz's (R.I.P. my friend) race prepped GT3 street car dyno'd around 600hp if I remeber correctly.
The M096 motor in the regular 996 can get gains in N/A form but will be limited by it's inherant design from reaching really high HP (wet sump, etc).
My understanding is that there is more power to eek out of a 3.4 than a 3.6. Porsche really did their work well on the 3.6. Eventually it becomes a dollar to HP ratio that you are comfortable with. Everything points to forced induction for best bang for buck ratio.
The superchargers are great on these cars and I have a friend working on a turbo system for the 996 for production.

I'd like to try it

but from a reliability standpoint i would rather NA tune than do any forced induction on a regular 996. i havent ever heard of anyone getting decent numbers with NA parts on a regular 996? i'd love to be wrong on that, anybody have any dyno's or numbers pointing to the contrary?
