Got back from Martin Michigan’s US-131 drag way this evening and finally made some time to post and reply here.
To say the least my MM ran incredible in the warm weather we had both days this past weekend. It ran 11.47 and 11.48 at 121mph and 119mph. And numerous 11.60’s and 11.50’s. The track prep was awesome and my 60 foots were right on… 1.67 to 1.70’s... still not equal to my best 60ft of 1.65.
The tune was the same that I took with me to Indy other then adding one more degree of timing at WOT over all. With all due respect this proves to me that the Indy track just wasn’t working in terms of traction. This is why most of us that went to Indy were 2 - 4 tenths off in the ¼ mile ET’s.
I really don’t see my MM going into the 10’s in the ¼ mile any time soon. It would require probably about another 100 – 150 horsepower or some serious weight loss to do it. 4400 pounds isn’t as easy to move as some of the 3400lbs Mustangs I’m used to. I don’t intend to do long tubes on my MM any time soon even though I know that they’ll be worth about 50hp on my current set up. I have 4.10’s right now… 4.56’s would be worth some thing I’m sure but still not going to those either. A loser converter is not going to do much at the level of low end torque I’m now pushing now. Plus loose torque converters aren’t all that great in heavy cars/trucks for over all drivability.
My car has now had the Trilogy blower on it for over roughly 18,000 miles. It makes about 14psi of boost on 93 octane and it’s driven and beaten like this every day when I drive it. When I go to the track with it, I pump in 100 unleaded. This is the only way I will use the Nitrous on top of the boost and is what allows such a huge amount of power to be added to a totally stock MM engine. The 100 octane is needed to keep detonation under control on this motor because of its 10:1 compression, 13.8psi of boost and about a 75 shot of Nitrous. My MM and the Trilogy number 1 and several other MM’s with Trilogys are starting to prove what I’ve said for years… the stock, cast 4.6L pistons, block and crank can handle a substantial amount of boost with a proper tune and octane. If my MM can take what I’ve been doing for the last 18K miles, imagine how safe only 9psi should be with a proper tune!!
We’ll see what happens this fall with some 50 degree weather…
Thanks
