Finally got around to replacing the in tank pump in my MM with a Focus pump that’s been getting great reviews from other Ford tuners around the country. This is the reason I’ve held off using the little 50hp shot of NOS on my MM on top of the trilogy’s 13.7psi of boost. The stock pump signed off at 440-450RWHP with the KB Boost-a-pump setting maxed out. This was all done with the stock filter and lines. Any one who thinks the stock fuel system on a MM when left N/A with only a few bolt ons isn’t enough is very mistaken. On a Trilogy car the stock pump and filter kept up with-out a Boost-a-pump until the high 300RWHP!
I finally started to spray the 50 shot and ran into several problems once I got passed the fuel pump issues. First off the car would buck and jerk and miss fire when the NOS began to flow. This was fixed by regaping the plugs to a tight .030 instead of the .035ish we usually run with boosted apps. Once I got passed the initial misfiring the car began to detonate severely at about 5500rpm. As I pulled timing and tried to tune around the problem I found my self negating the 50shot of NOS because I pulled to much timing to keep it from knocking.
So with out hesitation I made the decision to run 100 octane unleaded in the car when using the NOS on top of the boost. This allowed me to put back in the timing and fully sort it out, with out any problems what so ever. As I’ve always tried to instill amongst my customers with the stock 9.8 or 10to1 compression Cobra 32V’s …. that more octane is needed when getting into big boost… I even failed to listen to my own rules some times.
Luckily I managed to lift when I heard the knock and no problems at all have resulted with my MM’s motor. The final results on my dyno when it was all sorted out was 469RWHP. The peak RWHP number isn’t all the big of a deal but the peak torque and mid range torque are up dramatically across the board. I’m at home now but will post the dyno sheets and/or numbers on Monday hopefully. But for the most part the 50 shot of NOS was worth about 25-35 at different parts of the curve on the chassis dyno. On the day I tested the NOS on my car on both the street and the dyno it was about 80 degrees and the NOS bottle pressure was about 850-900psi. (NOS systems and bottles perform the best at about 900psi which is achieved typically at about 80degree temperatures).
Friday night I took my MM to Milan Dragway and literally drove it in off the street, teched it, added the 100 octane they sell there and proceeded to run an 11.79@116.9 with a 1.69 60-foot (awesome for this tank of a car)!!! Normally I remove my fully loaded trunk organizer and run the car with only about 3 gallons of fuel in it. This time I didn’t pull the trunk organizer, had about ½ a tank, added a full 34lbs NOS bottle and a few things in the back seat. I think my MM went down the track weighing about 180-200lbs more then when I normally have raced it lately.
Mind you this 11.79 was on the NOS!! I was fully expecting to bring home an 11.50 to 11.65 with the NOS on top of the boost. The traction was perfect. But the temps were in the mid fifty’s and I don’t have a bottle warmer (tight ass). So my bottle pressure was about 650-700psi! So basically the NOS at this psi only added about 30-35 HP I’m guessing and I didn’t bring the jets to try to make up for it. So between the weight and the NOS’s little effect I barley beat my best of 11.86 with out the NOS. And the track was so busy and behind I couldn’t make any more runs. That’s why I choose to spray it on my first pass as soon as I got there. I knew I’d only get one or two runs.
That ended up being my only run which I kinda knew was gona happing because of how late I got there and how crowded it was. So in summation for my car I think in the summer heat soon when its about 80ish it will probably run 11.90-12.00’s all day and then with the bottle pressure up where it should be I think it will go for sure mid 11’s with the NOS and the weight where I like to keep it normally when drag racing. But for now with the entirely stock exhaust I think this is gona start to be about it for this combo.
I do have some very stellar news about a customers 04 MM with did a full Trilogy and then some just recently. This person is not a member here so unfortunaly you wont here any more news about this car here probably.
He came to me and said he wanted guaranteed low, low 12s -- high 11s in the ¼ mile from his MM.
Here is the recipe it got;
All stock motor and internals, 14psi of Trilogy blower, big oval throttle body, 80mm Pro-M, Kooks long tubes and a full 2.5” exhaust with two cats and FlowMaster 50-deltas with the original tips ungutted, 4.10s with widened rims and the 305 Nitto drag radials, Bauman shift kit, stock trans and converter, focus fuel pump, larger intercooler heat exchanger.
This car because of the throttle body and full exhaust with long tubes made more power then my MM did on the DynoJet with the NOS! With 93 octane this thing made 474RWHP!! This is with out the blower porting like I have on mine!! On its first and only pass Friday night with me driving it knocked out also an 11.79 at just under 118mph. This is not NOS’d like mine. Just like my self he got there late and couldn’t make any more runs. Needless to say I had a very happy customer. I would have to say that the long tubes and the full exhaust accounted for about 30-35+ more RWHP then mine at this time. And the throttle body about another 10rwhp or so. One thing I’ve noticed for sure is that the ’04 MM’s defiantly have a looser/higher stall torque converter then the 03’s. This car noticeably leeps harder then mine out of the whole and pulled a 1.70 sixty foot at the track.
I know now that as long as the dealer can get it right I will be ordering the stock ’04 torque converter for my MM very soon. It seems to me to be just the right amount of extra stall for a MM with a Trilogy with the stock 9.5psi or greater.
Thanks
