and you prob do 'need' BBKs if you track the car with long sessions and / or are competitive

What he said! Maybe with some cooling the stock ones would have held up, but I go to some very brake intense courses and need the extra confidence of great brakes.

Lou i installed FI test pipes on my car and i have the FI catback with no resonators. I hear the hiss in the cabbin even at full throttle lol. ive never heard that on any of the cars ive had except when there was an exhaust leak but i dont feel any leaks when i put my hand up to the exhaust.

So as we all I know, I had a mishap at VIR. Thread is here: Me = 0 / vir tire wall = 1

Mike · 02-23-2010, 11:04 AM

I got the undertray off this morning, bumper and fender are next.

I found that one of the lines slipped off of one of the socketless aeroquip connectors, and the other one is back a little bit. I don't understand how that could happen, as when I made the kit, I had cut a hose a little too short, and could not pull the connector out. The only way to get it out was to cut the hose. Anyway, I guess I will be getting some hose clamps today and double sealing them.

I guess I can take some small comfort in the fact that I went off before the engine had a chance to blow, and that it wasn't something stupid like not tightening the oil filter or reconnecting the fittings to the sandwich plate properly last oil change, which is what I feared.

spearfish25 · 02-23-2010, 11:19 AM

Ugh, now even the aeroquips are suspect. Has anyone measured oil pressures? Maybe the car is operating at a much higher pressure than anyone expects.

ChrisSlicks · 02-23-2010, 11:27 AM

Damage doesn't look too bad, new fender, new bumper and crash bar, your $1000 headlight just barely escaped. Hood might be salvageable if you can find someone that can repair aluminum, door shouldn't be a problem.

The fact that your socketless aeroquip fittings managed to push off is very scary. These connections are supposed to be able to hold some serious pressure. Did you have anything else on the fitting externally such as a hose clamp or Modshack zip tie?

Don't need the crash bar, and hopefully the hood and door can be easily repaired. Probably going with the new Stillen bumper.

Didn't have anything else on the fittings, but I will now!

ChrisSlicks · 02-23-2010, 11:56 AM

I was curious about the fittings because there is the slim chance that adding external pressure could somehow compromise the design. Given that wasn't the case I don't know what the heck could of happened. Perhaps spearfish is right, the pump might be putting out more pressure than we think it is supposed to and we are creating a constriction that is increasing pressure further. Did you use AN-10 or AN-12 ?

Mike · 02-23-2010, 12:00 PM

10, I think.

Kind of makes sense, oil pressure would expand the hose a bit, making it fit more loosely, which in combination with high pressure, would cause it to work itself loose.

I'm surprised no one use a clamp in addition for extra safety...

spearfish25 · 02-23-2010, 01:32 PM

My other theory is that inadequate hose length and engine vibration/shifting under persistent heavy throttle on/off is causing the hoses to slowly work themselves loose. This is the second case of a hose coming loose in a setup with short hose lengths.

While I think measuring oil pressure at the level of these hoses would be very helpful, I think everyone needs to ensure adequate slack in these hoses (just an extra couple inches). Finally, a true stainless steel hose clamp that can be screwed down may be a good idea rather than zip ties.

HKYStormFront · 02-23-2010, 01:47 PM

really sucks mike, it honestly bummed me out for the rest of the day seeing your car bent up like that. even more so after the "unnamed other black car" went off. track activity dwindled down after that and everyone started heading home. like i said yesterday, if you need any help wrenching on the car, just let me know. i'll be glad to help

I have plenty of slack in my setup.

Patrick, thanks! Did you get pics of me while going off? If so, feel free to email them to me or post them here!

Mike · 02-23-2010, 02:43 PM

Also, I figured out that I didn't spin because of oil on the rear tires. The way the hose popped off, it shot across the underside and soaked my front left tire. That thing was covered in oil!

So, I hit the brakes and instantly pirouetted off the track.
