Good stuff, Rote

 

I heard from a friend that changing the Oxygen sensor is very imporant when running with a special catalizer

 

The stock O2 sensor bottoms out somewhere in the low 11's AFR. What looks like a steady 11.1 AFR may be a sign the actual AFR is much lower than that.

 

Which sensor needs changing, the one in the exhaust manifold, or the one that used to go in the Cat?

 

My LTT is in the 5s.....


I hope it stays that low...


OK, here is what I did:
I found two 3.5 inch 90 degree mandrel bent aluminum tubes 29 inches long outside the curve. (They were actually from E-Bay--- OBX made them)
Hack saw on one of the tubes to fit the top.
Nose and bumper removal.
Small adjust with a hammer and wood block on the VFAD opening.
Hack saw on one of the tubes to fit the bottom.
Moved my stock K&N (for now) to the space in front of the I/C heat exchangers.
Bumper and nose install.

Yes, I am sure it blocks some air to the I/C, but the 20 percent trim is gone.

 

so you needed cooler air or straighter flow?
glad the trim is doing better!
good stuff about the bottom end scale of our wide band.

Don't you have the ability to scale the maf ?

 

I do have a flash with a scaled MAF, but I am not running that flash. (too lean)
Now that I have my CAI and I seem to be doing better on the LTT, I may do more testing.
The first step was getting a stable start point.

 

The one going to the cat ... I have the re-amemyia catalizer so I still have my sensor....

 

So You do not run with the pettit flash ?! 'cause I am too lean too...but I didn't finished my installation since 2 weeks (too much work)

 

Both of the flashes I have for my car, came from Pettit Racing.
I have one made for the 570cc secondary injectors and one for the normal injectors.
The flash for the 570s was a scaled MAF flash.
I am not running the 570s, running the Automatic's 440 injectors with the normal Pettit flash and upgraded 14 PSI pulley.

 

Hey guys, new Pettit sc owner here. Will have my system in about two weeks and hopefully if everything goes according to plan will install it on the 4th of July weekend. Just trying to learn I all can about everything you guys did with your systems, but the threads are so damn long lol. Got to page 30 of this one...185 to go lol. Anyway would anyone be willing to make a nice summary of this thread perhaps. A summary of all the important things to take care of before installing the sc. Maybe some tips and pointers, etc. Im sure Ill be coming back here with tons of questions.

 

Congrats,,,,

Some things to look for have taken place in the last dozen pages with another new owner, just things to be aware of...

 

Congradulations Macius, JMKuco just installed his and had a few problems that you need to check on. Mine was installed early in the game and installed by CHR so I can not be much help on the install.

See the first post and send me your info and I will add you to the list and map.

 

hows that new map coming Phils

 

well I've had mine installed for a year and 9,000 miles. No problems, and some great fun.
Jusrt passed my MOT as well, which features emissions control if people are interested.

Just got back from my wedding and Honeymoon driving about the Island of Skye and the north west coast of Scotland.

Amazing wife, and amazing wedding and honeymoon. The roads out there are so awesome!!! Perfect for a SC RX8. Its born for it!

As for the car in its other natural habitat. I did an airfield (auto-x style day) and had the best fun with throttle controlled deliberate oversteer, going mental it was awesome.

here is some inside footage for a some delicious "violin" supercharger whine. I love it!!!!

When did you get married? I just got back from my 10th anniversary trip. Our anniversary was June 5th.

I got married on the 24th May, and the vid was done by a friend along for a ride.....

 

I put one up but it is not what I wanted. I just keep trying. Someday I will get it right. Being computer challanged is not fun, I know what I want but can't get it to happen.

 

HAHA! The story of life neatly summed up by Phil!

 

Just some randowm RX8 google image searching,,,
found this photoshoot of the Pettit BP build,,,

 

that sounds really sweet - better than my turbo i have to say

 

the sound is nice--and people on the outside can hear it well on track--they always commit about it afterward to me---hear it but not too loud. Turbo has a good sound too--just different.

SOmething new guys----read up about using diesel oil instead of the regular motor oil---we are starting to do that in GA--makes a lot of sense. If yall need more details I can get it too ya.

oh and by the way if you havent already taken the knock sensor off the engine and wrapped it in foam --you may want too. its useless anyway.
