hey ray i got a K&N drop in filter for my2003 corolla that i superchraged. Do you think it will provide any gains or torque loss.

 

If you keep that stock plastic box (in the middle of intake pipe) the low end power will always be there. A drop in filter wouldnt lose any power at all. Some gains my be felt???

I dont think theres going to be an intake that will keep the low end power. All there going to do is dyno the car from 3000rpms and up. Thats what I dont really like about the TCTunerz dynos. They start from 3000rpms and go up. I want to know what the curves look like under 3000rpms.

 

lol very true at one point one of their Dynos showed 130hp and 113 tq for and auto..lol really off, then another showed 130 hp 141tq for an auto TC, lol hmm big differences. Now they are sticking to one dyno. I emailed them and they posted more info on their project tc like tranny type and so on. The auto #s are 130 hp and 123tq to 140 tq.. wierd.

 

Don't know if anyone else noticed this -

in the article, they say "The Performance header installed dyno.. 138.9hp / 129.8tq"

But if you look at the dyno graph, it says "MAX TORQUE = 138.9 MAX POWER = 129.8" So it looks like it lost a little bit of whp but gained a lot of torque

 

The stock dyno chart says Max torque=130 and Max power=123. However above the dyno chart they listed the numbers backwards stating it had max power of 130 and max torque of 123.

So in reality it gained almost 7hp and 9 torque.

 

"Hmm, for a header with a cat in it (assuming that it will be legal becuase of that,) that's actually a decent performance bump."

It is against EPA and CARB rules to remove or replace a factory installed catalytic converter while the vehicle still has a factory exhaust warranty. If the original factory cat needs to be replaced due to damage or failure, it must be replaced with an OEM part.

Of course, if the aftermarket part in question passes the CARB certification process and is issued an EO Number from CARB, then you can legally install the part. Just because it has a cat does not make it street legal. Keep this in mind.

I agree!

 

Is there a pic of the honeycomb converter on the cat with this header set-up, because it still looks like a resinator to me.

 

Interesting, thanks for pointing that out. One more question though, do the CARB rules apply for states other than California? I know they're super strict on emissions, but I live on the other side of the country

 

Megan is a really good company.

Ill take any japanese performance parts over america. They are more reliable, trusted, and make great quality. they are also more expensive too.

too bad there isnt any japanese performance parts available now for the tC. (if there is post it here please)


as for the tctunerz new header, im pretty sure its not gonna out perform the DC header. with that converter in the way its not gonna be as loud without it.


Ima wait 2 weeks and see if anything new and improvement is going on. if theres nothing, ill take the tctunerz header. i hate that CEL light.
