Actually, I was trying to help you out. I was trying to be polite. I was trying to make sure that other people on this board were not misinformed by you. Because on the topic of FI, YOU ARE WRONG. You'll notice that I never once got into the discussion of who's car is faster. I never once called you a name, and I was never argumentative. I work for one of the best, most reputable Porsche engine builders in the country; turbo and supercharged engines. I've been wrenching on my own and other's cars for over 20 years. I have published articles on forced induction.

I suppose that any engine running doped fuel is also force induced since with additives like nitromethane you are introducing additional oxygen into the mixture. Actually... any car running on one of the ethanol fuels has forced induction as the ethanol itself adds oxygen into the combustion gases.

I know we can agree on this: It's pointless for either of us to continue to argue this issue.

 

i understand your position completely and youre completely right as far as semantics and definitions go. However, nitrous kits allow for far higher power gains than anything an intake, larger fuel injectors, and an ecu remake can ever make. IT should be considered a form of FI, or be in a class of its own withing the FI umbrella term.

 

Extra weight on the top of the car is not needed and horrible for several reasons on the track and so on, no track car needs the added weight yes, but also its not as rigid and losing that weight causes a lower center of gravity! I cannot believe you said it was a myth, i hope you are joking.

 

and i apologize for calling you a name. YOure absolutely right, i was out of line. You were just misunderstanding what i was saying. I respect the knowledge and the abilities of you and the entire crew over at IA!!

The difference is not discernible. This is coming from a professional driver (Mike Levitas, 2006 Rolex 24 hours at Daytona Champion). His shop is 30 minutes from my home, I guess he would know. So I'm sure an amateur like me would definitely not feel a difference. I also believe that although the new 997 Gt3 will have a sunroof (unfortunately), it will not have a great effect on it's handling. Do I want one with a sunroof? Hell no! Are we off the weight issue or shall we continue this mindless banter?

 

Of course we cannot feel the difference so much since we are not professional driver's or since our cars are not setup so much strictly for the track!

Point is, everyone is different and has different views and opinions. Because of what he says, i have to honor it and believe it, but forget what everyone else says? A guy i know in the viper club who also just bought a hardtop 996tt waited so long to find one and explained everything to me, he is a hired professional race car driver and ive been on the track with him in his viper gts acr!

 

Dude, I never said anything about anybody else. I said that Mike feels no discernible difference and that, "An amateur like me would definitely not feel a difference." Are we off the weight issue? Can we agree that losing 500 lbs is quite a stretch?

 

LOL i never argued that it wasnt a stretch, re-read please. Anyone can strip weight out of the car with EASE, it just takes your insanity, money and willingness to not be comfortable with creature comforts in a car. I'll tell you 300-350 was easy to strip and that was keeping ac and everything comfortable in my M3.

BTW you were trying to say that your friend said so, so its the truth, or at least how i took it! I have done it, and def. felt a difference whether it was in my mind or whatever, the car was much more nimble on cornering, it didnt feel like the weight on top was pulling my car to the side/body flex!

I was never in the weight arguement i could care less, just giving some info on someone who has been through it and done it BTW i cannot find a weight of an non sunroof turbo I think that's another reason my car is rather quick, its much lighter then your avg turbo!

 

I would give an uneducated guess that your car weighs about 30 lbs less than a TT with a sunroof. But then again, that's my uneducated guess.

 

Where are you getting 30 lbs from, you must have read it or pulled it out of somewhere, if so can you send me the link?! So far im seeing this, and this is with the sunroof! I want stock to stock weight of sunroof/non sunroof and cant find it.

Dude, I wrote, "An uneducated guess." What is your estimate? I think a sunroof and its components are about a thirty pound weight difference? Is that hard to believe? Does anyone else on the board have an estimate that they want to volunteer? I also believe that a TT with the tip is slightly heavier.

 

Tip 996tt is slightly heavier, and all im saying is one of the biggest weight reductions and changes besides awd delete to rwd int he GT2, is sunroof! All i know, based off what my M3 sunroof weight was, that 30lbs seems like way too little, why didnt they equip the GT2 with a sunroof then? Makes no sense!

 

Because 30 lbs is 30 lbs. Any reduction is worth it. I think the back seats and the spare tire would weigh more than the sunroof. That's why my 2 and my previous 3 didn't have a spare. What does a spare donut weigh? 30 to 40 lbs? Do you think a sunroof weighs more than a spare?

 

Funny, my car doesnt have a spare either, and depends on the spare, i havent seen one for the Porsche. But my M3 sunroof weight, with all of the mechanisms and mechanical **** taken out is 65-70 lbs or so, maybe some more, its not light by any means. BTW , hit user cp and go all of the way down

 

I appreciate the kind words dude. How do you recipricate? I don't know how to give anyone rep points. Or am I still to much of a rookie to have that privilage. Honestly bro, 40 lbs tops on a Porsche sunroof. Call a reputable Porsche dealer/service guy maybe he would know. There is a guy at Champion in Pompano Beach that I trust. PM me I'll give you his info. Or you can talk to a guy at TPC racing. He is pretty much their crew chief. He should know. He's owned and driven every Porsche known to man.
