Don't lug the engine that way. But, yes. 150 mph is about 6,000 rpm. Don't ask me how I know! So, at 50 you'll be turning 2,000 rpm. At speeds below 60, you should be cruising no higher than 5th. Both are overdrive gears. It is better to keep cruising rpm above 2,500 rpm so that if you...

How far back is the new cat? Even with extended wiring, it is probably too far back to get hot enough to work. How does your state inspect? Is it just checking codes, or is there an actual exhaust sniffer test? You may need to move that cat up into the racepipe section of your system to get...

$300 sounds about right for both rear B6 shocks. Check with our site sponsor vendor Edge Auto Sports for best price.

A converter that far back is not going to get hot enough to work. The cat need high heat. I'm running catless in a state that does not test. I don't know what your inspection tests check for. If it is a tail pipe sniffer put your cat farther upstream in your test pipe. If you need it ahead...

It is most likely pulling in air through a vacuum line or hose involving a connection between your MAF housing and the turbo. Check the TIP connection on both ends -- to your MAF housing and to the turbo. Check all vacuum lines to and from the TIP including the lines on the electronic boost...

I like the more progressive feel of the HPS. Progressive pressure = progressive braking force. I don't like the brakes all out there on the tip of the pedal. I guess it's just a matter of preference. I now have 92,000 miles on this car. The OEM pads went about 35,000. One set of Hawk HPS...

Let us know how it goes. Chassis dynos are good for before and after mod comparisons and changes. They are not so good for establishing absolute and true numbers. Too many variables are left to the discretion of the operator, who can make it look good or make it more honest, and the machines...

Forgive my stating the obvious, but maybe you should ask BNR.

I just did in editing my post. You need better logging equipment.

And your point or question is? Your logging device has very low resolution. Look at all the repeated frames. True refresh is as low as one per second. That is too low to evaluate the performance. Bad things could be happening between refreshed data fields. Otherwise this is an example of...

Good to know about the Porterfields. I don't run autocross, but have pulled the car down pretty hard from triple digit speeds many times. I guess I'm not doing it frequently enough to induce the variable pedal you're experiencing. I do need for them to be quiet. I'm at 91,000 (about half...

Here in the Deep South we're lucky to get four years out of a battery. Didn't matter what type if car or battery. Long summers and 100+ degree temps are not kind to car batteries.

I know this board has gotten a little slow , but reviving a 5 year old thread? We've learned quite a bit about this issue since then. Much of the early speculation in this old thread was not borne out over time. There are much more detailed and accurate analysis threads with datalog and...

Once the shop gives you good computer generated alignment data, if you find you have excessive negative rear camber, it cannot be adjusted because stock camber arms are not adjustable. You could install adjustable rear camber arms to fix that. But if it's really far out, you need to make your...

Wow! You responded to a dead thread with the last response (me) almost two years ago! And I was ranting about the prior poster responding to an already dead three year old thread. People here do report their problems. That's one of the main purposes of these groups - to help each other, so...

Replacing rear shocks is an easy job of about 15 minutes per side. Front struts are a whole different story. Anyone with a floor jack, one jack stand and a few basic hand tools can do the rears quickly. Do not buy OEM crap. Above recommendations are solid choices. However with stock springs...

What does this have to do with car audio and electronics?

Never heard back from OP. It's frustrating to offer advise or ask for more information to try to help someone and never hear back. Makes me reluctant to try to help. Feedback would have been nice. Problem was two months ago.

If cost is not a factor, consider Yokohama Advan Neova AD08, my choice. They are, however, top tier summer tires. Probably the best combo of uber dry traction and tread wear. These tires stick. I drive this car hard, have 37,000 miles on them, and can probably make it to Spring before...

How are you using the acronym TP? Are you meaning downpipe -- DP? It is common and preferable to run 3 inch dp/rp combos necked down to stock CBE by way of an adapter. No real reason to run 3" all the way back. If you use the proper adapter, there will be little to no added restriction...
