Jake Raby exhaust evaluation

[Jake Raby]

None of the data has been posted, and it probably won't be... As soon as I mentioned it arguments began and thats something that I simply do not have time for these days.... Plus lots of people are rating the exhaust systems on sound and weight, and all I care about is RPM range and net power, especially torque..

I continue to gather data, I just finshed this testing today... 3 engines, same car.

All started life as a 3.2, the control is the lowest output run.. The 247HP run is a stock 3.2 bottom end with a nice valve job, bump in CR and cam timing alteration... Its got A LOT more left in it, it still had the 3.6 flash in the ECU in these tests..

The 286HP run was a stage II 3.6 that started life as the bone stock 3.2 that made the lowest power on this graph (it was hurting)...

Jake - Is the Stage II car still a "street engine" that you could expect a reasonably long life out of? Figuring drive train losses that puts your stage 2 cars well north of 320 hp at the crank plus gobs more useable torque....SWEET!!

I hate to ask, but why do you care about the people who are going to argue about cold hard facts? They will always exist, and they will always be vocal, but why let them have that warm feeling inside that they can keep you under their boot?

I personally don't care much about sound changes nor do I care about installing expensive exhaust systems, but I do care about knowledge. I enjoy the sound of my stock '98 Boxster, and don't have any plans on installing a different muffler for a different sound, but I wouldn't mind knowing if there is a better set of headers that I can install that might increase the low to medium range torque on my car.

I had a wonderful experience a couple Fridays ago by taking my Boxster out onto HPR (http://www.highplainsraceway.com). One thing I noticed is that some of the corners I needed to be in second gear, because if I was in third gear, I would be between 3k and 4k rpms, while trying to climb uphill, and the 2.5 could definitely use a boost of torque in that rev range.

Everywhere else on the track, the car is perfect.

I love reading about your methodology when it comes to testing a theory.
Unfortunately, you are worried about what 2% of the people are going to say about the results of your data. The other 98% of us don't care about that 2%.

BC.

The joys of crossposting... Of course a "Parrot" ended up posting my comment about armchair wrench turners over at PPBB at the link below..

http://www.ppbb.com/scgi-bin/boards/986/main.pl?read=1527015

I stated exactly what I feel and will stand behind this, because I am confident in the abilities of the components we have developed,and the data I have collected from them through time in the lab and in my personal cars. This data is continually supported by the results that others experience through first hand experience with the components- not assumption. (JFP's experiences are just one example)

Of course I cannot reply to the posts of those on PPBB because the site "expelled" me....

PPBB has a lot of great people, but it also has some people that are totally in left field.. They have no data and probably don't own a tool box, but they'll argue based on something they read in a book...

So when all the traffic from PPBB comes here to look at this post that was linked, just realize that you aren't getting the "Rest of the story" about why I am not welcome to post there... They never did deposit or cash the check that I sent them for sponsorship of the site for some crazy reason.. It's been MIA for over 6 months now.

I was treated like a red headed step child on PPBB and my Clients had their posts deleted for absolutely no reason.. The answer is YES, I am bitter about this! Anyone with a spine would be just as bitter... We are busting our asses to develop and create solutions (and SHARE them) for these engines and what do we get in return??? Pure BS!

Feel free to crosspost this. I stand behind what I post, just like what I develop.

As long as Jake Raby is going to relentlessly continue with his hijack, I would like to add my 2¢.

PPBB is a free discussion board. One of the common topics is "is this product any good?" Your products are fair game.

How can you (and why would you) make personal statements about someone's qualifications when you know absolutely nothing about them?

The truth (and discussion about what is the truth) is the friend of the honest businessman and the enemy of the dishonest.

That's fair if Jake is allowed to freely participate in the discussion too. If his posts are deleted and he's asked not to participate at PPBB at all things get just a little one sided pretty quick. He's out there actually doing work on these cars and posting results. It's really easy for some others to hide behind the internet and post whatever they want with no factual basis for anything.

My 2 cents is PPBB lost a very valuable resource when Jake was kicked off and are much worse off for it.

I don't think it's necessary for the designer of a part to be involved in a discussion for the discussion to be informative, interesting, and even illuminating. After all, Porsche doesn't have reps online in the discussion forums defending every complaint against their cars or addressing the claims that their parts are insufficient.

I have never heard of PPBB deputies deleting posts or banning people for no reason. And they do respond to questions about why posts have been deleted.

The archives for PPBB are available and they prove that Jake's posts are mostly about self-promotion, self-aggrandizement, putting others down, and little about informative content.

I don't doubt that Jake has a lot of valuable experience and information but as far as PPBB is concerned, it's not a big loss for the above-mentioned type of posts to be discontinued.

It's interesting that Jake does almost none of the negative stuff you decribe above on this forum and provides a TON of informative content......hmmmm. Since you indicate its no big loss for PPBB for him not to post on PPBB anymore perhaps he can spend more time on this forum. We'll happily take it! Sounds like a win-win for both forums!!

Jake keep up the good work. As far as PPBB goes thats the place I go to learn more about carbon fiber trim pieces or best type of wax to use on a new 987. You dont belong there. Stick with more technical sites. Us folks who know about issues as well as potential of M96 are behind you. Your reputation with this platform will take time just as it did with T4's. Most of these guys dont know how you go after engine platforms.

Youre used to this stuff from 914 world and you developed the leading edge for the T4 platform. No doubts you will do similar thing for M96.

I just need to figure out what I'm going to do with my race car so I can use some of the parts you are developing! Boxster is sort of odd duck in SCCA racing. I'm trying to figure out best class for my diverse interests across AX, hillclimbing and perhaps road racing.

My little 2.5 Box recently set an SCCA GT3 class record at a hillclimb that has been held for 23 years. I'm still thinking a small displacement high output Boxster has a home somewhere.
