    Paging Rob Ketcham: Your hp issue

    Rob, your PM'ing and email via the forum is turned off... so i'll post this here:

    I suggest you talk to Chuck Mallett about your low hp issues... Last time I spoke to him I asked him about his thoughts on rwhp of the V vs. the Z06. As part of the conversation he mentioned that he knew of a V that made ~300rwhp and that was a mfg defect, the factory installed the "blah-de-blah" backwards. Unfortunately, I dont remember what part he said, but he was very specific. He might be able to give you some information on what to check on the car (or have a shop check).

    Also, if you do not have a scanner, you should get one (AutoTap or Ease PC)... this might give you insight into what is going on... Knock Retard, running on Low Octane tables, bogus air intake temps, torque management kicking in, something...

    Good luck.

    Re: Paging Rob Ketcham: Your hp issue

    I really appreciate your paging me. I'll do as you say. The background is that More Performance in Charlotte put their air box with K&N on the car, but did a baseline run first before changing anything. It put out 293 at the rear wheels, then changing out the airbox and doing their upgrade they got it to 317 on the best run (of many). The graphs were not smooth, indicating the computer was sensing something wrong and limiting power, like a knock retard or whatever. Anyway, More tried and tried that day but couldn't figure it out and left me to go back to Cadillac. The tests they have subsequently run at my dealer indicate that there is something wrong with the MAF, but they are spooked by the More air box, alleging that the oil from the filter is affecting the readings. For this reason they want to do their testing using an original air box. Therefore I have tried using this site to find someone with the original air box, and one man who lives in VA e-mailed me to say he had sent one per my request, but it has never come in and I left mine in NC thinking I'd never need it (its no longer there either).
    It is a bit frustrating since I'm heading out Monday for a drive that will be around 2000 miles and all this will just have to wait until I get back.
    I guess I could just drop by Mallet on my way back, will have to see if this could fit into the return route, which would be great.
    You do have me wondering what might have been installed backwards.
    Thanks again for your post.
    Rob

    Rob - something that can easily be reinstalled backwards would be the MAF sensor. There is an directional arrow on the body of the MAF. Double check yours to make sure the arrow is pointing towards the engine and not the air filter.

    Did MorePerf log any data such as knock retard, ignition timing, MAF sensor frequency, etc. during the dyno pulls?

    Thanks for your response. I'll check out that sucker in the morning, nothing ventured, nothing gained. I assume your word "air" meant "arrow". Is it actually visable without taking stuff off?

    Good thing to check, but Mallett mentioned a much more complicated part than the MAF... Something under the head!

    Here's a picture taken standing beside the driver's side front tire and looking towards the front of the car showing the MAF sensor. The black plastic MAF sensor body has the words FLOW and an arrow pointing in the direction of airflow which I've circled green and highlighted in red. It is highly unlikely that yours is backwards, but I learned a long time ago to check the simple things first.

    The oil from the K&N filter may have gotten the ultra-sensitive wires on your MAF dirty. You may wish to try cleaning the wires using an aerosol can of electrical contact cleaner from your local auto parts store.

    Wish you were closer, I'd hook up EFILive and see what your MAF sensor was putting out for flow numbers.
