Does H&R Racing have a website.

Thankyou for educating me on how to use a "simple" search engine. For your information I already did a search using Google.com, but I wasn't looking for "H&R Springs". The website I needed was the "H&R Racing" website. I understand that "H&R Racing" deal with performance modifications such as headers. If you would have another look at my initial thread you will see that I was asking if H&R RACING had a website, not H&R Springs. The two might be the same, but that is why I asked the question because I didn't know. I had previously looked at the H&R Springs website, but couldn't find a link to the H&R Racing site. There might not be a H&R Racing website, but again that is why I asked the question.

Thankyou. After searching for a while I also thought that maybe I was mistaken. The reason i thought that H&R has a performance division is that in the thread "Who Out There Have Headers On Their 3rd Gen?", started by IMPACT, is a reference to H&R making headers.
Following is a quote from zoompr5man reply.

If anyone knows if this is a mistake or how to find out more information it would be much appreciated.

Thanks,

I think you are looking for AWR:

No, the thread he mentioned did say "H&R Racing" and that they had o2 sensor mounting points unlike AWR's racing headers.

This is part of the email that I received back from AWR regarding the header.

I wrote:

Hello,
I wanted to know how far back this header goes and what type of termination it has.
Does it mate to factory cat back flange?
I am assuming there are no provisions for an O2 sensor(s)?
Thanks in advance,

The header picks up the original flange under the motor. It does have provisions for o2 sensors.

Sorry for that then. I had read on another thread that it did not include the O2 sensor mounting points. Either way they claim they are not even sure what will happen with a stock ECU.

BadDSM

Only because they have never utilized it on a stock car.
I dont see how an exhaust system would need any recalibration of the ECU in order for it to run correctly.

My ex grew up in williamsport and my current girl and my best friend are outta Harrisburg. My girls Cousin is attending main campus.
Is that where you are at?

TDK

I think the recalibration would come because of the O2 sensor. Without the cat the sensor might be getting slight diferences in temperature. So this would mean that the ECU might have to be programed to accept or acknowledge the changes.
(I'm guessing)

Also, if they haven't utilized it on a stock car then what config. are they running?

As the name implies an O2 sensor "detects" the level of oxygen in the exhaust stream. You need to add a o2 sensor "tricker" to the second o2 sensor to let the computer think that there is still a primary cat in the works.

Sorry, my confusion came from a conversation that i had with a header manufacturer. He told me that the sensors were heat sensors and that the sensors report to the ECU the temp. of the first cat and the second cat. He said that if you remove the first cat and not use the sensor, the ECU will get incorrect temps. and start to overheat the engine to compensate.

This is what i have been told, not what i concluded myself.

Stay as far away from that person as possible.
And place your money even farther away.

It's funny how some call themselves "professionals".

Regarding the ECU, you are probably right that it (alone) would not effect the performance, however it is a racing header and is most likely tuned for a very high revving, high output engine. I thought it was for the AWR's Speed Challenge car or something that makes around 240whp N/A (obviously, with a header) a good bit more than a stock FS. I would bet that it is tuned to give great high end breathing (most likely around 6,800 rpm or more) The torque is probaly gutted and you won't even notice decent power gains without a high revving setup, which in turn is related to our ECU+cams+intake manifold+head= the remarkable power drop off at around 6,000rpm. Our engines cannot breathe for **** at those revs. The AWR header was designed for an FS engine that could spin a hell of a lot faster than ours, and I would be willing to bet that it would not help much with a stock FS.

I am at University Park as well. I just realized that it has been warmer in Alaska for the past 1 and a half than here in State College. Averaging around 10* F during the day. Whats that girls name?

BadDSM

Regarding the car. I believe that there might be some loss of torque down low but the car would deffinitly pick up some power in the 4500 + range after switching out the stock highly restrictive cat/manifold.

Regarding the girl. Her name is Amanda.
