Here is his original post:

If he wants to get above 300 HP that sure sounds like he wants the power of a V8 to me.

I'm not knocking V6 Mustangs or their owners, but if someone craves 300+ HP then I'm simply pointing out it would cost more to bring a V6 car up to V8 performance levels than it would be to just go buy a V8 car.

 

Ah did not see that part, apologies. But I still don't see a GT trade for cheaper than building a sixxer OP already owns. With depreciation, and the extra costs of a GT (insurance, and associated fees for a car purchase) I think an X charger, and an 8.8 with the necessary supporting components (tuning, etc.) would be less than the hit OP would take trying to trade his six in and paying for the new car.

I guess he could find an older GT with more miles as that would be a much better deal, but that opens up new issues with the TSBs that come with early model S197s.

 

Aaquib hit it perfectly. I don't want to deal with the expenses of a V8. I'm just trying to add some extra oomph and fun to it. The 300HP comment was just looking at 2013's having 305 vs my 210.

 

I went the FI route and I'm pretty confident I can smoke a stock 4.6 and 3.7. That's good enough for me.

 

Put the Borla Stingers exhaust, Air Raid Cold Air Intake and BBK 73mm Throttle Body on my 2012. Put it on the dyno without a tune and only realized about a 25hp increase.
So don't take the claims in the ads too seriously. A tune will probably get you more but you're talking another $300 to $400.

 

What's FI?

 

Sorry. Forced induction. A super charger.

 

Or turbo of course.

And yeah, F/I is really the only way the 4.0L is going to see the 300HP + neighborhood.

The OP mentioned being worried about the mileage on his engine as far as adding some boost. As long as it's been reasonably well maintained, the 4.0L seems to make up for what it lacks in stock power, with solid reliability and longevity. I know at least one owner of a 4.0L that went F/I somewhere around 90K on the motor, and was still running strong pushing up towards 200K when he sold the car in favor of a newer pony (and that was with regular track trips). I wouldn't truly worry about only 40K or so as a starting point.

 

I put mine in around the 40k mark. She's now at 50k.

 

Great feedback, thanks. Who makes a good super charger? I was thinking that over a turbo, as I get the power right away, but was told turbo is the way to go with a v6. What's the story on that claim?
