Hey Joe,

Come to think of it I guess I have read about the little transient “noise” inherent in knox & other sensitive sensor circuitry. Didn't put it together with the expression “acceptable knock”. I wonder how you measure it (Ive heard of little microphone in the eng. Compartment...). Guess the EGT gage should say it all though.

EGT sensors are all hooked up. Kinda remarkable how much heat the super creates.

Funny I never thought to pick the brains of the big GT boys on 6Speedoline, felt like I might as well be coming around in a soap-box derby car. Every time I hear of, or am thinking of, something I want do, a Google search always winds me up at some rice burner forum.

Must say I've learned one 'elluva lot at those forums. Those guy are doing it all every day and to the max. Aside from this little cadre here, It's pretty hard to find anyone doing much ongoing stuff with the Boxster.

I'm still waiting for my little custom h20/meth widget controller from Aquamist (its real the...guy sent me a pick). RMA'd my O2 controller and it turns out there was nothing wrong with it at there end so it's coming back, not sure where I'm off on this end. Thought I gave it all the once over twice.


Regards, PK

Good evening everyone,

You mention that the sc creates alot of heat. Did you get EGT readings prior to installing the sc? If so what was the baseline compared to now?

A few more gauges will be one of my summer projects, dont worry guys I have something pretty sharp up my sleeve.

With the dropping in price of the Boxster and the racing series getting off to a good start I think more and more shops will make Boxster specific parts for the engine and suspension.

There is allot of knowledge to be learned from the "ricer" guys. I find myself reading the super streets type of magazines to see what they are doing. I agree that they know what they are doing and they push those cars to the edge.

To update you guys on my car, I added the lower suspension mount a few weekends ago, it makes a difference!! I think the difference may be larger in my car with out the aluminum plate than what most guys see. The cars with the plate do see a large difference, so I am not sure what the plate does. But because of my intercooler I mounted it below the mounts.

In the picture the bolts where not tightened but i promise they where before the test drive.

And to everyone:
More (horse) power to you!!

Gary

Good thing I plan on keeping this car for awhile otherwise I'd cringe on how much I'm probably going to spend on it once power gets done and suspension needs to be addressed :ah:

All in good fun though. In time these cars will catch on as certain stigma's have to be broken. It took nearly a decade and a half to get the E30 and E36 BMW guys to get up to where they are now in terms of power mods for decent cost and our platform will face a teething phase as the previous generation of owners will get replaced by ones who are more daring when it comes to modifying their cars. When it comes down to it, the answers have already been laid out by the import/domestic crowd who have been dealing with (engine wise) on how to get the best out of a high compression low boost situations.

PK:
Thats what a knock sensor pretty much is, an electronic microphone. The hard part is to program the DME to recognize whats knock, whats not, and whats acceptable and whats ideal. That meth injection is going to rock though

Gary:
Thats going to be on my next thing to get list. That and some nice R-Comps

I just got my little custom h20/met valve controller from across the pond. Pretty cool how it works. I'll be able to meter out the cocktail and into the intake with the precision of a fuel injector. Probably far more accurately then motor will ever care.

So ya, maybe I won't ever be challenging the Knock sensors. But a microphone eh, no sh_t. I suppose though if you could capture the DME processed & calulated knock signal, you have sound a buzzer or somthing. On the wireing diagram for the DME, I think it shows an unused pin labeled "knox"

Your right that the go fast technology is pretty established. I think the Japanese cars have a leg up though in that they don't have very high compression. I think those guys running a 25psi boost are doing it on a stock block. If we really wanted to, we'd tear our motors down and get some custom lower compression pistons & rings...they can be had... 'bout $100 each

Stay tuned

Hi Gary, Everything is set and car is on the road. No dyno yet but car spins easily on second gear with 275 35 18 tires. Methanol keeps engine run smooth under boost.
I will be back with up to date performances pretty soon

Jaques, How are you metering your meth?

Hey Gary
-----------------------------------------------------------------------------------------------
I unfortunately had the super in long before the EGT jazz was installed. The only benchmark I have is an article I stumbled on, regarding a Land Rover, saying 700c was nice, 780c was pushing it.

Assuming my gage is reasonably accurate, I'm in that ball park under pretty full load down the freeway. I've never heard a ping or knock under heavy load (not sure I would though)...might go for a romp with the motor lid off and the top up, pretty sure I'd hear anything ugly.

So, I figure I'll probably be using my current temps as a bench mark.


The suspension bars got to make a huge diff. on your car without the aluminum plate. Trivia; long before Pedro started selling those things a guy name Ernie (I guess) created the DYI “Ernie bar”. There was a thread about it somewhere around here.

I just got my little custom PWM valve controller from my man at Aquamist. Got to pickup a little PWM valve and I'm going start putting it all together. Also, I'd like to find a digital data logger so I can figure out what my 7th injector is doing and when to program a preliminary map for my new AIC.

More guages,,go man go...

Regards, PK
