Any car that's been driven with a BHG should have the block pulled, disassembled, and the bearings checked... or better yet, replaced. They aren't costly, and they are often in sad shape.

With all the fixes you've applied, it might be worthwhile to reset the ECU so it can relearn. It's probably learned really odd settings with the TPS out of spec and the ISC dirty...

Try to blow through the line when the engine is cold - just disconnect it from the BOV, and blow in the end. If you can't, the line is plugged, which is rather common. Often it'll still work when hot, because the line gets plugged with gummed up old oil from the PCV system over the years, and...

That'll buff right out. j/k! Seriously, though, I've seen Panther out here repair rims in significantly worse shape than that.

That's the problem... I've done these before, and after you've done one, you tend to wish you hadn't. They sure do work well, though. Next time, I figure I'm going to find someone parting out a shell, and cut out the hatch floor. Then I can build most of it in the garage, and give the...

I've heard of some people pinching the pipe shut and welding it. I really have no idea how well that would work, my knowledge of welding is really weak.

Nicely done. Want to make me one too?

Post up a time slip so we can see where you can improve... if you're already doing decent 60' times though, chances are you need some more ponies.

Well, there's the obvious upgrades to a full standalone ECU. Haltech has a plug and play harness, and they aren't the only ones out there. Bit pricey, of course, but the end result is so much better.

There's something wrong with the clutch then. If it's in gear with the clutch pedal depressed, and it tries to move when you engage the starter, then the clutch isn't disengaging the engine from the transmission like it should. Hopefully it's something with the clutch hydraulic system - the...

As long as you don't get compressor surge when you let off the throttle - which would sound like a fluttering noise from under the hood - you're fine. Chances are there will come a time when you can out flow the stock bypass valve, and at that time you'll need the aftermarket one. Usually when...

Dude... I'm lazy. You left out the most important bits... is it a mk1? A mk4? Engine? Transmission? Tires? What lane is your time? I'm sure I could figure all this out if I did some digging, but as I said, I'm lazy. Make it easy for me, and I'll put it up right away. Make it hard for me...

What if you start it in gear - does it try to move, even with the clutch in?

You MUST be referring to the support brace. The cross member is the BIG piece that the steering rack and suspension is bolted too.

Usually it has something to do with the fact that higher weight oils have all kinds of symptom curing benefits. They produce higher oil pressure, mask the sound of failing rod bearings, and even leak less on the driveway when parked! How can an oil that produces these results not be better...

Hey, Duane and I have both run passes faster than 12 without any of that except the slicks.

Actually, I've heard of a lot of problems with HKS units - compressor surge being the worst, especially under low boost, and leaking being another. I recall watching a video where some fellow had mounted streamers on his, then stuck a camera under the hood and taken some video to prove his...

It wouldn't be too hard to figure out. You'd need to measure the diameter of the valve (the actual part that moves) and the distance it moves, on each unit. The calculation from there is the simple surface area of a cylinder: 3.1415 * r ^2 * l where r = the radius (half the diameter) of the...

Well, to be honest the fact that hundreds, if not thousands, of Supra drivers are, in fact, using one is a sign. Hell, *I* have used one, and it worked fine - and I've had surge, so I know what it sounds like. Just not with that valve and a stock turbo. He may be thinking about modern 3.0L...

Actually, you've got it already, that's exactly what it's doing. The thing is, the ECU in closed loop can self correct a bit, and it learns as it goes. The ECU has 5 settings: - I think we are much leaner than we should be according to my maps, so I'm adding lots of fuel. - I think we are a...
