bad cats will definitely affect power... but usually you will hear them by the time the break up to the point of impeding flow...

if you have a CEL (and the code is O2 sensor - presumably is since you referenced it as being cat related), it could be precursor to failing cat (often the heating element goes bad and throws a code) - cats could be getting too hot and the filter media might begin to break apart... if you start hearing a rattle under the car, replace soon.

 

not to discourage you guys - but cams are not worth the expense (not even a little bit)... without doing a full build (which gets pretty expensive)...

when I did cams & headers - no one (that I know of) did it without a full build... I wanted to see what kind of gains could be had (since there was nothing on any forum at the time)...

Knowing what I know now - I wouldn't do it. However, back then the mod bug was deeply rooted so I was spending money on the car (even when there was a chance it was a waste - in fact, even when I KNEW it was a waste)... now I spend it on arsenal (my new money waster - err, I mean mod hobby)

So, since I know you guys are still fully addicted and the mod bug isnt bored with you yet... maybe go for it (just dont get your expectations too high - its about the worse $ per hp mod there is).

Just think of the killer AR you could built with that money (hell, two or three of 'em!)

 

we've done several - not necessarily annually... they are always pretty good...

I will say; Shawn and I discussed some ideas for a future event... I'm not going to disclose details yet - but coincidentally it might also involve a track (as well as dyno) a mini meet/show - and.... gambling <--- not racing for money

Stay tuned

sorry for the multi posts guys... I was in jury duty all day - so just trying to catch up...

 

Sounds good!

 

Sounds really good. Im definately in.

 

Thanks! That's good to know, i do hear a minor rattle sometimes....the weird part is that I had the cats problem CEL (forget the actual code) on before i swapped them for the test pipes but when I put them back on, the CEL hasn't come back on...weird...

I should be replacing them soon tho, so hopefully we have another dyno sometime soon!

 

while I'm still trying to comprehend what had happened to me at the Dyno day, I want to thank Shawn and Mike for setting up this event... It was small money for BIG gratification for knowing something more about my car; a truly rewarding experience - yes like prize-winning rewarding!! And it was nice hanging out with everyone there, it was a meet with performance as the common topic, and I'm so glad I participated, definitely the coolest event ever!

 

Ray it was definitely cool to meet you. In some ways I'm jealous of your enthusiasm, even though my car has come a long way from stock. It gives me goosebumps to see someone that's relatively new to the G scene so excited and hungry for as much knowledge as they can absorb.

I think the free tune ended up in the right hands fo sho! (Peter, I had really hoped you won the other one. )

 

ello Driving Enthusiast, Can't wait until our next event on Sunday, Dec. 11th at Buttonwillow Raceway? Then come out to a Buttonwillow Open Test day on Friday, Oct. 14th. This is an event where the track itself opens their doors to anyone wanting to drive on the track. This in NOT a Max Grip event but simply Max Grip staff and friends will be attending to have some fun on the track. The cost is $200 for full day 8am to 5pm and $110 for half day but they do afternoon half day only meaning from 1pm to 5pm and you pay the track directly. Additional information about the track can be found at: www.ButtonwillowRaceway.com If you are interested in joining us, we will be meeting at 5:30 am and leaving at 5:50 sharp at: Bob's Big Boy 8274 Sunland Boulevard Los Angeles, CA 91352 It is about a 2 hour drive from there to the track. Hope t
o see you

Sounds good. Ima gonna start a thread on it today

 

then I might be better with 660cc injectors?
Just not too much out there on testing these with our vortechs

 

Law I was reading over on My350 that people running better w/cats & Vortech. someone had the MD XYZ and swapped the cat module in and out and did a back-to-back dyno.

 

Theoretically you'll have more potential to push the car without it running lean, but it doesn't necessarily mean that you will make more power.

Tony and I were talking about that recently, the only problem is, cats in an FI application will clog up fast. But Tony's working on that .

 

nice info Fab, thanks for chiming in

 

that is very good info. I need to learn more if i am going to do this to my G.

 

I'd be more than happy to place a little wager on a road course.

How about WSIR? I'll be there 10/9. Lets see how much power your car really has

I'm sure you put down more than I do.
