Thank you for enlightening me.

 

That's what I was trying to get to... everything works as one system. The OP cannot just say this and that are waste of money because one component may need to work with another component(s). I think we are on the same page.

 

Interesting.... The UMW tune raises boost from .9 to 1.1 which must equat to a substaintial increase in HP and Tq unless the computer is pulling back tons of timing.

That said, was the stock tuned w/exhaust car you raced an X50/S car? If so that would explain some as 60-140 an K24 car would have the edge.

 

Yup, its all good. The only way i see this as being helpful is if we knew how the part worked or didn't work and other supporting mods and or goals. Not just, i had "xyz" part and its not worth it.

As i work on my build, i will try to dyno one part at a time. I will try to report real world data, according to my build. Not being a millionare, this will take some time but, i will report all..

 

This. We need to introduce him to Ben (not Moores, Bad 107). Many of us have run the "tests," as to what works on these cars and the list has been very well established.

Back to the OP, these need to be removed from his list: 3" Y Pipe
Larger Intercoolers (unless you want to go 800 Bhp)
16K Billlet Turbos

Also, intake plenum produces benefits before 800 whp, not in hp, but in faster spool up and power down low.

 

Todds point was that what works and what does not work has been thoroughly vetted. For example, there were pages dedicated to the larger plenum. Many pointed out that it did not increase power as claimed by the company selling that product. However what was eventually established was that it enabled high hp cars to make more power at a lower rpm (say 3800 instead of 4k) If you have been a member and regular reader you would know that fact.

Another example, we also had many many discussions over creating a fast car with a tiptronic. Craig (most of you will not know him) an early participant on this forum dumped tons of money into his tippy project with poor results. Todd also made the same attempt and finally (and wisely) decided to go w/ a 6 speed for a big power car. The same applies to IC's, new members come on and claim that the big ICs are a scam etc. when in fact they are a critical component of high hp set ups.

Nonetheless, we still have new people come onto the forum, reject our collective wisdom and insist they can do things that have been proven not to work well.

 

Hold the conversation a minute....I have to go pop some more popcorn.

Actually, I really like this kind of exchange of ideas. It really helps us Porsche-shoppers in the decision process.

 

Dr jitsu, thanks for taking the time to explain. While searching for all the results is a good thing to do, the OP just listed items and gave a, "yes/ no" rating. While i don't fully agree with the premise, it is somewhat helpful. My initial response was, great as it seems to ME that, there are a few items that get reviewed based on seat of the pants feelings.

If anyine thinks i am coming on here and saying that i know what works and doesn't work has misread my post. That being said, jumping on anyone case for not searching or knowing something is a bit rude and in a public forum, not very inviting. Seriously, i am here to talk about these wonderful cars and find out what people have done to their cars and more importantly, hear how people are enjoying them! I'm not here to be told my post count is to low and therefore can't post my opinion.

 

I think a better way of posting this thread would have been more along the lines of "What mods give you the biggest bang for the buck?"

For example, the billet K16's are obviously an upgrade to regular K16's. But is it worth the money to buy the billets when you could put it towards another mod that may produce more gains?

 

well I am very pleased there is so much active debate on this topic ! we all need to know what works together well and how or not at all

 

+1. Can't feel it, but not doing it can sure hurt later.

 

Exactly. The OP set this tread up on a more yes and no type basis. There are many variables with each mod mentioned. Some seem to be good for some and some seem to be good for others. It probably has to do with the combo each has put together more that each part "working" or not.
Funny "race gas" never made it to the worthwhile mod list....

 

Maybe the thread should read..Mods Waste Your Money......LOL

 

I know I am a noob to this forum also, but definitely not a noob to turbo AWD cars. I have been modding mine since '94. I have been lurking and reading here for several weeks. I also came from the DSM (eclipse)/EVO forums and they are drastically different. There is good information here and some members that have contributed a lot.

I think the above feeling comes from people spreading 2nd hand information. These cars are fairly expensive so you don't get the level of modification that you do on some of the other forums, so there is not as much data from the actual user being posted. Dyno sheets (besides from shops) also seem hard to come by. With the other forums I am on 50% of the people are running bigger turbo's, IC's, injectors, exhaust, fuel pumps, aftermarket ECU's, etc.

I am getting my 996tt in the late spring, so I am trying to figure out my upgrade path to get me where I will be happy with a reliable ~700awhp.

 

Absolutely.... show me another gain that will outperform a turbo upgrade boost for boost.... ( tune required of course...)
