Hillclimb Mach 1

[nekasrof]

I've started this thread in response to a request in another thread. Didn't think it right to hijack with this amount of info. So..........


Mobil1Mach - I wouldn't call it amazing really. It's a 20' car regarding paint. Racing has taken a toll but it doesn't look bad.

Here are a few pics and I'll add some specs afterwards:

Cobra R brakes:

Remote oil filter:

1/2 a roll bar tubing welded to the k-member for oil pan protection at Giants Despair as I WILL hit the ground with it. 10AN lines for remote oil filter.

Duryea turn 2, wing off.

There are very few things still original on the car. Body, rear housing, interior, brake lines, abs unit, rear sway bar and......fuel feed line. Most other things have been changed at least once, if not many times.

Last pull with the car on the dyno, hood down, it put down 518. We had the temps as high as possible so coolant temp was like 180 or better, I can't quite remember. We've seen hp as high as 524 with the 3.6 pulley on the D1. This is a very conservative tune with timing at 15 deg, knock sensors on and timing to be pulled as heat builds in several areas. I think it was Giants Despair this year, my data log showed 6 deg of timing at the top of the hill. Coolant was 225, IATs were 174.

A lot of things to list with the build.

I am sure I have forgotten something or another in here. We've bene thru lots of parts in the 5 years we've hillclimbed this Mach 1 and we aren't done. It's difficult to do any R&D at all with this form of racing as it's on the street and we can't simply shut the road down for test and tune, LOL! Boy do I wish.

I THINK I have finally gotten the rear suspension correct. An adjustable rear sway bar would be the only other thing I need to put on the car. A good friend of mine, Mark - from Pittsburgh, has been a really great source of info regarding suspension changes and has helped immensely.

The front suspension will be worked on this year some more. Although the car is wicked fast, I think improvements are needed. Coil overs are an absolute NO at this point. I am not willing to cut up the front fenders to get them to fit under there. Tires are like 1/8" away from the strut and regularly rub.

Motor is good.
Tune is awesome.
Tranny is taking me some time to get used to. Don't ask why as I have no clue!!!! Should have been an easy transition so we'll see what happens next year.

We're in the middle of doing some testing for PA Performance with an alternator that you may see available thru them at some point. Those guys are great to work with. Bummer is that it's getting cool out and we'll have to wait til next year to really test in the heat of racing. The original alternator had the voltage down to 12.5v above 5k so that was doing weird crap to the fuel pumps. All fixed now. Actually had to go back and adjust injector pulse widths to get the AF corrected.

Turbulance in the MAF had us sending the pre-tubing attached to the MAF out to ProM so they could flow the meter with the turbulance and generate a new transfer function. THAT was an easy fix....a little costly but done proper.

Started with a Spec 3+ clutch and wound up with a stage 3. Actually an easy clutch on the street. Way different than what I had read on many forums where guys were stating there was a lot of chatter with that plate. I haven't found that at all. A little here and there but nothing bad.

We've gone to the 3.4" pulley on the D1. A little more belt slip than the 3.6". Haven't done a dyno pull yet. Will have that soon.

I found that the wing helps with certain corners but all in all, it slows me down. Picked up 4mph(127mph to 131mph) at the finish at Duryea and .6sec. Went from 109mph down the short straight at Jefferson Circuit to 113mph. While it looks cool and adds some down force, I really think it's a detriment in hillclimbing. So I don't know whether we'll race with it next year. May just leave it on initially and then just pull it off. I did get a bunch of people asking what happened to it at several races cause it was on initially, then off. Hehe.

Hillclimbing is a fun racing series. We're always looking for more to join. More mustangs, ESPECIALL Mach 1s would be awesome.

That's one sick Mach 1 man!

That's one sick Mach 1 man!

+1 I agree, got to love a mustang in general that can pull off that wing. Looks great :beer:

 

[Robman420]

Your mach is simply badass, ive been watching your vids on youtube looks like one hell of a ride:rockon:

 

[4v_mach1]

damn thats nice

 

[cobrakidz]

very cool.

Thanks for taking the time to post up detailed pics and specs. Your car is really impressive.

I'm in the process of getting my car ready for open track events. So far just suspension/tires/safety/cooling stuff. I'm going to attend my first HPDE next month. I'd love to give hill climb events a shot but Texas is pretty flat and we don't have anything like that here.

Is your battery in the trunk? Is it worth the effort to relocate it rather than dropping in a lightweight race battery? Also, you posted that the hood vents helped you out at Mustang Week- have you seen a difference in temps during race/track/hillclimb events?

I'm sorry for the late response. For some reason I am not getting email notification of responses.

Thanks for the kind words. It's been a work in progress for 5 years. Crashed it in '08 and had it rebuilt in less than 2 weeks for the next race.

Vents, I believe, are helpful. I cannot give any hard evidence other than that. You can deffinitely feel the heat coming out of them when the car is sitting still. The cooler temps at Mustang Week were a combination of the 160 thermostat, cooling fan on at....170 I believe, distilled water/water wetter and the vents. As far as racing is concerned, I am certain that combo has helped. My coolant temp at Giants, at the finish, was 198. Last year, NA, it was 215 or better.

Here is the difference between start line temp and finish temp. This is @ Giants Despair in July after a 1 mile run. ECT is coolant temp off the factory sensor.

Saw this car at 2011 Mustang Week, what a badass car!

The battery is in the back seat, on the passenger side. I had to move it for several reasons. It wasn't that much of a pain and really was a bonus to have it closer to the fuel pumps to minimize the voltage loss as the pumps are directly run off the battery. Voltage is 14+ with the set up I have. I had a drop to 12.5v with the heat that is being generated under that hood. Voltage correction was a must especially in the FI condition.

For the long Duryea course, the coolant temps were pretty high. So were the IATs. Here is start line and finish line. Bummer is that I have NO in-car from Duryea this year.

Finish line:

The heat is a killer. You can see what the timing was at the finish.

Thanks for posting your info.

I assume the battery is mounted on the floor pan that would normally be under the back seat? Are there no SCCA/NASA restrictions about having the battery mounted in the passenger compartment?
