Has anyone tried sport throttle bodies for the boxster any year ?

[BoxsterRS]

What pros does a sport throttle body have over a stock one, other than saying "sport"jeje. Is it a worthy investement or just another way of saying consume more fuel yeah its sporty!!! I have seen them on s-Car-go websites and fvd. Pretty expensive for something that doesnt give any plus to the car that I know of hope to have feedback on this subject

I've seen some of those same parts. My guess is they are only effective if used in tandem with other modifications. It will be interesting to see if anyone has one in their car.

Hi,

Many cars are seemingly Made for Modding. Great improvements can be made to the OEM design.

Not so with the Boxster. Porsche did a fair job of maximizing the design on their own. There are relatively mild gains, for what to me at least, seems an exorbitant cost.

Lots of Suppliers out there make some pretty hefty claims, but when you boil it all down, the gains available in HP, Braking and Handling are really limited, especially when compared to some of the gains achievable with some other cars, such as Mustangs, MB, any of the Japanese offerings, etc.

I think one risks upsetting the Balance of the Car quite easily if a comprehensive series of Mods are not planned out from the start. Unfortunately, most people do not do this and Mod in a Helter-Skelter fashion driven primarily by WOW factor and the present state of their checkbook. But whatever, they'll learn...

Happy Motoring!... Jim'99

Blablabla. Is this your salesmanager talking ?

Porsches are just cars, just like others (sorry guys). My 3.2S puts on 252bhp which is 78bhp per liter which is nice but not very on the limit. Modern NA sportengines are expected to put out 100bhp or more per liter in a reliable manner.

Look under you car at the exhaust headers. I have never, ever, seen such crappy headers.

There is much to gain, however you will loose reliability (wasn't that perfect to start with) and pay premium dollars for intake, exhaust and remapping modifications only. After that you can do cams, throttle bodies, porting of the head, etc. ,etc., etc.

Don't get me wrong. I really _LOVE_ my S and find it a near perfect car and I wouldn't think about putting mods on it. I'm an originality freak and like the car just as it is.
(but don't say its tuned to the maximum engineering limit and can't be put any further. That is completely XXXXX)

What MNBoxster is not complete bs like you state. I do not know where you get your information from but you should reconsider what you said. MNBoxster knows more about Boxsters then 99.9% of the people who own them,so you should really respect whatever his input is.

You said most cars should put out 100hp per liter? Are the 8.3 liter Vipers supposed to have 830hp,but instead have 500hp?

If the headers on a Boxster are so crappy then why dont more people have problems with them?

You also say that there is much to gain from the stock. Not so true besides supercharging,alot of the aftermarket parts lose low end power with minimal high end gains.

I agree really. MNBoxster and some people in this board seems to know a lot about cars. Wise people should listen or at least respect to what wise people said

As far as what I can comprehend, Boxster is not a simple car where you can just add this and that because it will offset the balance easily. Of course, knowing that, people are free to do whatever to their own car and learn and have fun

Thank you for your kind words. But, not to Diss anyone, but you don't need much Higher Education to make a living either Assembling Cars or Servicing them.

The most important thing for the DIYer is Confidence. These Cars are not Mysterious in any way. They may be more complex, but that's not insurmountable. You need Knowledge (which any number of Tech Manuals - Porsche, Bentley, etc. can provide you). A Basic Understanding of Cars in General, and a modest set of Good Tools. Armed with this, most R&R on a Boxster can be performed by anyone. Experience helps, but you can only gain this by doing. The major adavantage to Experience will be found in developing your Diagnostic Skills, but with OBDII and Code Readers, much of this is done for you as well.

In the case of DIY, the Car is already assembled by someone who knew how to do it. Take care when disassembling a System or Component and you'll learn how to reassemble it. Work slowly and purposely making sure you've not forgotten anything and do the job right the first time.

But, first, you need Confidence. This can be gained by first starting small. Work on the easy tasks, and once you feel more comfortable, move on to more complex ones. Your Confidence will increase with each completed task, such as the work you did on your MAF Sensor.

You said most cars should put out 100hp per liter? Are the 8.3 liter Vipers supposed to have 830hp,but instead have 500hp?

To be sure, HP/Ltr. is a Valid Metric, but maybe not the most important one when determining the Performance Potential of a Car. Maybe a more important one is the HP/Weight ratio.

In the case of the Boxster 2.7L, you're looking at 1:11.9 HP/lbs. This Compares very favorably to the Famed 550 Spyder, whose HP/weight ratio was 1:11.7 HP/lbs.

The reason this metric may be a better one to use is that it provides an alternative - Pumping up the HP, or... reducing the weight! Two ways of attacking the problem. To be sure, there are trade-offs. People may prefer to add HP instead of swapping Wheels, the Battery, Spare, etc., or losing the Stereo or other Creature Comforts. But, the alternative remains. And, you can do some of both and achieve the same end all the while preserving Reliability and Cash Flow

You also say that there is much to gain from the stock. Not so true besides supercharging,alot of the aftermarket parts lose low end power with minimal high end gains.

Very True. Power and Torque Curves often shift when Modding the Car and all too frequently, Gains in one part of the Curve are offset by Losses in another. Where's the sense in gaining 10HP at the Top End (where a Street Car is rarely driven), only to lose 10HP in the Mid-ranges (where you'll spend much of your time)? On Paper, it may Look Better, you can spout a lot of Auto Dribble to your Friends and Brag about your Automotive Jewelry, but you may actually have a poorer Performing Car with respect to how You drive it.

In the end, all-in-all, the Boxster is a nice little package pretty much as-is. If you're looking for more, you may find more satisfaction pursuing a Viper, C6, 997T T or the like...

Happy Motoring!... Jim'99
