In development land, refactoring is something we call when an issue has been discovered, and it requires rethinking the approach and reworking the code. The next step of Mustang project is pretty much refactoring. I’ve been rethinking about why I can’t really harness the speed as well as I would like, and I’ve put together a comprehensive list of what will be tackled.
1. Front end geometry: When the engine was built, I decided to shift it back on k-member 1 inch backward for better weight distribution. One thing that I discovered is that when you do that, the front sump of the oil pan gets in the way of the steering rack, and the rack has to be shifted down to clear it, which in turn requires to adjust for bumpsteer. Doesn’t seem like a big issue until you realize that even when you max out the bumpsteer adjustment, you are still nowhere near where it should be. To remedy this, I had the engine moved back to original position, set the rack back to the center on the adjustable bushings, and dialed in the bumpsteer with the gauge to almost no change at all (as close as it would get to 0 toe change).
2. Hydroboost: As some may know, I’ve converted my car to hydroboost in order to be able to utilize the brakes to their maximum potential. The conversion consisted of hydroboost unit with master cylinder and pedal box from 96-04 V8 powered car to line up the pushpin with the pedal. I decided to power the unit with the stock 94 power steering pump. The issue is, that the pedal doesn’t feel anything like you would find in a normal OEM application. The travel is short, the pressure is really hard, feels like stepping on a rubber ball. I’ve had a chance to drive a 96 GT, which has a full factory hydrboost system, and I’ve realized that the pedal feel is completely wrong on my car. Since the power steering pump is the only piece that still hasn’t been converted, I assume this is what I need to fix. I have to keep a couple of things in consideration, such as size of power steering pulley and crank pulley to make sure that I don’t over-drive or under-drive the pump, and mounting it will be a separate challenge all together, since they are completely different mounting styles.
3. Oil rings: The motor is consuming oil like crazy. Having eliminated everything else, looks like oil rings are not doing their job well. I can see it smoking oil out of the tailpipe, and level goes down pretty quickly. Looks like Wild Pony Motorsports strikes again. Absolutely everything that shop touched about this motor is total shit. I’ve asked for a quote regarding how much it would cost to fix the issue, still waiting on the current shop to get back to me on that.
More updates to come soon hopefully.
