anyone intalled NHP full exhaust???

[stephen wilson]

I'm sure Jake is very good, and I'm glad he's helped develop an IMS bearing retrofit.

Having said that, many of his posts ,on this as well as other forums, come across as very self-serving, designed to generate some buzz about his company.

I know which brand oil is best, but I can't tell you. I know exactly what's killing IMS bearings, within a certain RPM range, but I can't tell you that either. I could tell you the best header, but I'd have to kill you, etc. Why throw out teasers if you're not even going to hint at the answer.

I'm not trying to be a troll, it's just frustrating for people who want answers, not more questions.

Rather than look at this as “viral marketing”, try running a business (or even a website) that develops a following, and then use Porsche’s logo; and then watch how fast their army of lawyers slaps a “cease and desist” order on you. And they are hardly the only ones that respond to every perceived transgression with litigation; we live in a litigious environment were small businesses have learned, often the hard way, to be less than forthcoming with opinions, even well supported and documented ones, less they spend a lot of time and money defending their statements. And even when you “win”, you are still out a lot of money………………….

Walk into my shop and ask me my thoughts on this cold air intake or that brand of oil, and I’ll pretty much tell you my thinking. Ask me to post the same thing online and you’ll get a more watered down (read “evasive”) reply………

[stephen wilson]

That sounds reasonable, but don't make a comment on a public forum that you can't answer there.

If you stop and think about it, Jake did answer the question, but just not in absolute terms you seem to need:

"You'd have to be in my position to understand the flack that gets started when a discovery is made and shared.. Gathering the data scientifically without variables being imposed is hard enough, dealing with the people after it happens is unbearable.

Lets just say if you like to sound like you are going faster than you really are, then you'll love most of the after market systems."

I know how I read that, but your interpretation is up to you.............

[tnoice]

yea, this is fun, little bit of forum banter.

[stephen wilson]

JFP, you are correct that it's not enough information if you are trying to decide which exhaust system to purchase.

Jake, I'm not in the market for an exhaust, and can sort of read between the lines on oil selection, they were just used as examples. The thread that aggrevated me was when you suspected the cause of many (most?) IMS failures, within a certain RPM range , but failed to elaborate. That information wouldn't give Porsche or any parts suppliers reason for litigation, but could help people like me greatly. As with many, that failure is my single deterrent to Boxster ownership.

Again, I'm not trying to be a jerk, just trying to minimize my risk in owning one of these (mostly!) wonderful cars.

UPDATE

I know a few people are following this thread. I'm on a plane tommorow. and have the Base line dyno scheduled for Friday July 3. Will post vid results. Then should be able to intall Full NHP following weekend.

results coming soon

thanks

[2K3_Boxster_S]

going to dyno tommorow. (pre-install numbers)

Unwrapped parts. Excellent quality. welds look great. good penetration. heatshields on the mid pipes and the mufflers. gaskets for everthing included.

[23109VC]

i'll be anxious to see the results!!!

you have an S - my car is only a 2.7L base - 217hp...so whatever gains you see - i'll have to expect less.... lets hope you see massive gains!!

are you doing any kind of ECU flash or just bolting on the system? is your system the entire thing - headers/midpipes/muffler?

[Adam]

The parts look high quality and the tubing diameter is noticeably larger than stock. Definately interested in the results.

[2K3_Boxster_S]

Dynoed Today on a Dynapack, so there would be no questions about variables. there are no tension straps, no rollers, wheel spin, deflection etc.....

Video Results of my stock 2003 Boxster S:

Looking at back on Dyno in 2 weeks Full NHP installed.

1. I am doing this at a 1 step at a time approach. (yes I will be altering the ECU maps, custom tuned. but later) The reason is I want to know as well as others whether Porsche has detuned the boxster through the exhaust or the ECU or quite possibly both. (Porshce did not want Boxter's threatening there 996 owners).

2. Yes, 1st stage is strictly bolt up exhaust that should determine if flow is restricted anywhere.

3. Yes it is Full NHP exhaust as follows:

Headers:
Equal Length primary piping, mandrel bend
Racing merge collector for primary piping
42mm primary piping vs. 36mm stock piping
200 cells sport catalytic converters vs 800 cells factory
2 inch exit pipe vs. 1 3/4" stock exit pipe

Mid Pipe Bypass pipes:
Completely removing rear CATS
50mm versus 40mm diameter

Exhaust:
304 Stainless Steel this muffler is a straight through pipe design
there are no internal baffles

Your engine is rated at over 250 flywheel HP.. If his dyno is that stingy, it's inaccurate. These engines generally lose a max of 15% to the drive train as RWHP.

Find a dynojet, the numbers from unit to unit are near exacyting and the industry standards are set on dynojet units.. Thats why I bought one instead of a dyna pack..

I have engines tested in either of my engine dyno labs, install them into the car and generally see a 13-15% difference from flywheel HP to RWHP consistently.. Thats how I know our numbers are spot on.

yes, i think its kind of strange the guy that dynoed right after me was around 40 hp under what he is used to seeing. that would put me exactly on the average you said you see for an S. 223 hp. i'll look for a dynojet.

thanks

I would....there is usually just a 1-3% difference between dynoes so there is something else going on. I've heard the dynapac's are stingy, but your hp #'s are similar to what early 2.7L engines put out, not even close to 03 S power. The huge drop in the middle of your torque curve is very strange as well. The TQ curve should be nearly flat.
