12s N/A possible?

Looking through the timeslips, there is only one N/A Marauder in the 12s and he had a 5.0 Big Bore DOHC V8. The next closes to his 12.9 is a 13.5. Are 12s N/A possible on a 4.6L Marauder? What mods need to be done? Why has nobody done it?
 
Barry (Cruztaker) has come the closest so far on a 4.6L engine.

I believe that he ran 13.2s before he went to a power adder on his 4.6L engine.
IIRC it was on an OEM engine also!

Maybe he can elaborate on his mods...

Getting a 4400 lb automatic sedan to run 12s on 281 naturally aspirated cubic inches is a REAL feat!

It is possible....with head work, cams, gears, many other mods and lots of rpm to make up for missing torque.
How much money do you have to put into a 4.6 DOHC???
 
I'd love to get there eventually but it's going to take a while. We'll see where I'm at this spring with my latest mods, a torque converter and TB port matched to the plenum.

Did you pick up Mongoose's TC?
 
Too much $$ to get the car to run a mere 12 something, thats why a power adder is so sought after on these.

Someone needs to find a way to toss twin turbos in one of these mofo's.

Yes.
Stock motor with no forced induction.

Very cool evening, using a Lidio tune for 110 octane.
I had all the basic bolt-ons with 4:10 gears. I was using a 3000 stall and the j-mod on the trans. I was also running worn slick 295 Pirelli street tires.

With slicks, I believe I could have broke into the 12 second area that evening. She ran 13.2xx all evening hot lapping.

That would kind of defeat the purpose of running 12s N/A.

Cruztaker was the fastest on a stock internal N/A engine. I have most every bolt-on except headers and a race gas tune. My fastest is a 13.6@99mph. I hope to have headers and a strong tune when I make my next run for the N/A title.

All of my mods are in my garage link on my sig.
 
Cruztaker, can you be more specific about your bolt ons? Did you have exhaust work done? How much of a difference does 110 octane make?

4.56's. A good exhaust, intake, high octane tune with correct fuel, slicks, basic weight reduction, Pulleys, electric water pump, spacer, just about ever N/A addon.

Should be possible. The KEY ingredient is the gears... 4.10's arn't nearly enough for an N/A marauder. I was planning on 4.30's in mine but I didn't because I had a reality check with how much I drive it.

There is a mustang twin turbo kit available for the mustang, I'm sure that it could be altered enough to work, the problem is that it mounts at the tail pipe.

Ctrlraven in only 13.7?

Nitrous might get you there.

I did 13.7 with minor bolt-ons, stock gears, weakened stock diff. No juice for me and I will have low 13's with a stock motor.

Yeah I know right lol.

I still have full exhaust (LT headers & bigger exhaust piping), 4.10 gears, pulleys and whatever else left to do. 4.10 gears, axle rebuild and bigger cat-back piping will be going on Jan/Feb just in time for racing in March and I can't forget I will have to get another awesome tune by Zack
