Suggestion
Now if Porsche was using Aisin-Warner transmissions of a similar design to the affected units you mentioned, and the Sprint Booster actually was a modification that had something to do with changing the line pressure, you might be on to something.

I am running a Tip though, and maybe the performance result with a manual will manifest much differently, but my inkling is that a SB with a manual would be killer.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I ordered mine last week, the part arrived late yesterday and I installed it this morning. Total installation took less than 45 minutes, couple of notes:
-only a single philips screw needed to be removed to mobilize the HVAC vent
-the most challenging part was separating the stock connector, and inserting a large flathead screwdriver in the connector really simplified the disassembly
-inserting the SPB was much easier, and I was able to insert the modified connector into the stock mounting bracket w/o issue
I've taken a test drive and my initial impressions are: WOW! I really didn't expect such a noticeable improvement - it's the second best mod I've done yet next to my sport suspension upgrade. Car is an '02 C4 cab w/ Tip.
I can't possibly imagine sending it back for a refund at this point.
The throttle reponsiveness has considerably improved, and it's almost as if the TCU was reprogrammed as well, as downshifts happen easier and sooner. The quality of the driving experience has definitely increased for me.
For a tip-based 996, it sure awakens it and makes it feel more responsive and connected. I can't comment on track applications or w/ a 6-speed. My S8's have S mode tranny and while this feels similar it has a different feel to it. If anyone in CO wants to test drive to compare, let me know!
^^^ I was going to say this sounds like the �S� mode in my DD Tip B6 S4 Avant. It may not put any more power to the ground, but for a tip, it�s like a Jekyll and Hyde experience. Throttle response is exponentially higher, the shifts feel faster, and it utilizes the V8 to its potential; read: it goes like stink. I wouldn�t want
that
drive mode all of the time though, even for a weekend car.
I find that if I am not aggressive on the pedal it feels more docile, sort of like it did before the SB went in. You notice the most 'zoom factor' if you are more agressive on the pedal. The company also makes a Racing version of the SB - but my thought is that the verison I installed is perfectly fine for street use. I am running a Tip though, and maybe the performance result with a manual will manifest much differently, but my inkling is that a SB with a manual would be killer.
And - to beat a dead horse -you can send it back if you don;t like it.

No affiliation, just a delighted customer. I wish someone would try it on a 6-speed and report back. You'll notice the difference right away - it should either be good or bad.
Which is probably the actual cost of this unit. Besides it is such a useless waste. Just my opinion... I also feel the 'sport' button in my e46 m3 is a joke.
The manual transmissions aren't likely to have DBW throttle opening rate "detuning/derated" in order to accomodate a reduction, "loss", of ATF line pressure with the engine at idle.
Most new, modern automatic transmissions no longer sustain line pressure at a high level when there is no need, simply a waste of fuel. The line pressure sustaining/holding accumulator has been eliminated in favor of real time control of the ATF line pressure.
Why pump ATF fluid in volume and at high pressure just to have it bypassed back into the sump...
Good luck with that Tip overhaul upcoming soon.
This handy-dandy Porsche Power Tube would probably work for such discriminating drivers as yourselves - heck, you could probably install it yourself between classes during your lunch break. And as a bonus, it probably falls well within your 39 dollar budget unless you plan to expand your paper route?
I can't comment on defeating the clutch switch, but I have installed one of these in a 996 6-speed, and I can tell you that it makes an incredible difference.
Aside from being more responisve to throttle input after clutch engagement, it also transforms heel-toe downshifts. If you guys have ever tried this, then you know how the delay makes timing it properly a bit awkward. Not so with the Sprint Booster...
It really makes the car alot more enjoyable and we've actually had customers say it aided in throttle modulation at the track instead of making it more difficult.
In a 996 6-speed, if you look under the dash with the clutch pedal up, you will see it presses on a button (black IIRC, maybe red). There is an audible click when you depress the clutch enough to disengage that button. In order to defeat it, all you need to do is tape the button so that when you press the clutch it does not release. It takes about 2 minutes to find the button and 30 seconds to tape it or untape it (unless you're skilled in the use of tape). The effect of doing this is similar to what SprintBooster users are describing and I'd like to hear about the possible impact of doing one vs the other or both.
Its not about budget home skillet. (or trying to insult people!)
imo. value for dollar is poor with this device, some people (obviously like you) just dont get it. and fyi, I work on a 911 ambulance.
I do believe that's the suggestion, it's a sound argument theoretically, assuming line pressure cuts or is very low at a stop/roll. I believe that assertion is true, the trans clunks much harder at a roll for 2-1, will verify. I'd like to see the long term results on other cars with the same trans, will search the Benz forums.
I agree that the pricepoint seems a bit much considering the implied components required to achieve the result, which is true of nearly all "hop up" parts on Porsches, but I must also say that the majority of $1000-$1500 chip tunes available have "improved throttle response" as the only detectable improvement. I for one have a very, very heavy right foot, so I'm not sure this would help me much!
Tim, you up for Photoshopping us a Porsche 911 ambulance for illustrative purposes?
Doesn't matter how 'heavy' your foot is - the egas systems senses throttle position and pedal application 'rate' and opens the throttle accordingly. The SB speeds up the 'rate' of desired pedal application to the throttle body - way faster than your foot. So if you have a heavy foot or a fast foot, the SB gives revs to you 'faster' even. The 996 has a doggy throttle opening rate or 'feel' anyway - the SB puts it closer to an analog olde-timey 'feeling' pedal/throttle system. In the olde days with linkages, bell-cranks and springs, you could achieve the same thing by tinkering with throttle cable cams, etc. BTW: But don't worry about it, some folks still belive the world is flat too
Doesnt'; matter where you work - it all comes down to disposable cash flow. Largely folks that can't or for any number of other reasons, cannot access a 'toy', treat said toys with disdain and dismissiveness or even more hilariously, hollow arguments about 'value for the dollar'. I challenge you work up and present a cogent and persuasive business case analysis to underpin your 'value' statement - why not? Because you can't - you don't have the facts nor the knowledge base to do so. Don;t sweat it and keep in mind that the world is flat.
I sure didn't mean to create such a stir when I posted this thread - only to comment on my positive experience w/ this mod. As I mentioned, I've done LOTS of mods to my P-car and this is the most significant upgrade besides the sport suspension. If a $1,000-1,500 ECU chip upgrade provides not much more than improved throttle response, then I'd have to say the SPB is the best bargain out there.
But I can't imagine any of the doubters here have ever invested in a chip upgrade, because that would be an enormous waste of money...
Possibly, not probably.
The engine/transmission controlling ECU may be programmed to open the throttle "slowly", or even delayed, in order to give the clutches time to fully and firmly engage.
A quite famous, infamous, instance of this is ocurring currently with many Toyota and Lexus FWD and F/awd vehicles. In ~98 T/L began revising the transaxle design in a way that resulted in a high failure rate in the transaxles. With the introduction of the RX330 they began using DBW to prevent engine torque rise during a downshift until the downshift could full complete.

Not really sure what a completely unrelated problem that occured on 150,000+ mile Toyotas (which use a completely different transmission manufacturer and design btw, and were not even drive-by-wire) has to do with the Sprint Booster on an E-gas Porsche.
Now if Porsche was using Aisin-Warner transmissions of a similar design to the affected units you mentioned, and the Sprint Booster actually was a modification that had something to do with changing the line pressure, you might be on to something. But as it stands, it looks like you are trying to make a mountain out of a non-existent molehill...
I find it interesting that ALL of the negative comments are from individuals who have not tried the product. Everyone who HAS installed the unit have had nothing but positive feedback. I for one enjoyed the sport mode on my M3 (I just did not like having to activate it every time I drove the car) and that nonsense about it making the throttle hard to modulate? I have never heard an enthusiast say "I think my car is too responsive, it needs to be de-tuned a bit". Regarding the SB's price- almost everything for these cars is expensive.
Barely noticeable? Is that truly how you describe your test drive?!? Please describe your installation experience as well. Any pics to share? We're waiting...
