Jerry Barns from Trilogy told me a little while ago that he wanted his Marauder to be faster then mine for the ’05 season in the quarter mile.
So over the last few weeks, a game plan started to come together for what we would do to achieve this goal of his.
As a refresher my MM has gone a best of 11.47 at 122mph in the quarter mile at a tad over 4400lbs. This was accomplished with totally stock exhaust, 4.10’s in the rear end with widened stock wheels plus the Nitto 305 drag radials. The Trilogy blower making about 14psi of boost and a shot of NOS that’s adding another 80hp on top of it all. When I use the NOS and achieve this performance out of my MM I use only 100 octane unleaded fuel so that it will live longer and better prevent detination under these conditions.
We’ve known that on any MM with a Trilogy that there is a minimum of at least 35-50 extra Rear Wheel HP, by going with the Kooks long tubes, and a full 2.5” exhaust. So that’s exactly what we did with Jerry’s Marauder number 1. In the last few days we’ve completed the full Kooks install and also used the kooks supplied X-pipe with two cats and Kooks mufflers as well. Then from the mufflers back I had the rest of the system custom done in 2.5” also with delete tips. And on top of it all Jerry and I decided to also go with an 80-90 shot of Nitrous on his MM as well. The little shot of NOS just like my MM would require the 100 unleaded (or better) race fuel. Just like my MM the NOS comes on only at WOT and when the NOS is switched on the chip goes into a secondary mode that pulls some spark and adds fuel accordingly, because its what is considered a "DRY" Nitrous kit where you only inject NOS into the intake and no additional fuel. The additional fuel is handle by the computer. This makes for a far more reliable NOS system and greatly reduces if not eliminates the chances of a Nitrous back-fire.
Any way to rap it all up. Jerry car on our Dyno-Jet Dyno with the new Kooks headers and a full 2.5” exhaust has now produced 462-RWHP and 469-RWTQ. This is on 93 octane with the stock throttle body. A couple of other MM’s with the same exact combo will make 470 to 480 RWHP when the have the large oval T/B we some times use.
Then when we used the shot of NOS on Jerry’s car with 100 unleaded in the tank…. The RWHP jumped to about 530!!. I say “about” because theirs a little spike at the end of the pull. And the RWTQ jumped to a max of 575ft lbs !! Not to shabby.
Jerry’s number – 1 Marauder now has just over 40K on the ODO since the Trilogy blower went on. So far the motor still sounds and feels like new. This car is not lucky. Its living proof that with a safe tune, these modern 4.6L’s with their non forged pistons can live for quite some time with even 10-12psi of boost. Not just the stock 9.5psi of a Trilogy kit. Its hard to say how much longer Jerry’s T - 1 will live at the level of power its going to now make especially with the NOS. My own has now gone about 18-19K with the blower and the NOS and lots of mostly high 11 second passes and several very mid 11 second passes. And its gona get it just as hard the 05 season when my Mach-1 is resting.
I’ve posted the Rear Wheel dyno sheet from Jerry’s car with the best pull it made with the Nitrous. Of course like any other MM I dyno now days, the torque converter is locked in 3rd gear for the whole pull. The amount of mid range TQ on this thing is serious.
Thanks
