4.6 2v power a little low??

If it's a PI engine on a NPI tune, I could see 230 hp to the rear wheels being right.

 

totally seems off but i also agree with royal

 

then something seems way off...

 

So is it a full PI motor (with the lower compression bottom end) or a pi swap (pi heads on npi shortblock)? Because an 01 GT only made 260 HP to the flywheel. Factor in your typical 15% drivetrain loss and you're looking at 221 rwhp. Exhaust and timing can only get you so far. Still sounds normal to me.

 

Make sure it doesn't have a Doormann (sp) intake.

To be honest I don't think it sounds off at all. Factory PI motor came with 265 crank hp, when factoring in about 15% drive train loss that is about 225rwhp. To say he picked up 12rwhp from long tubes and a mid pipe on a stock PI motor if anything is generous.

 

Mustang's suck. These things are super weak

 

Perfectly normal then. These things aren't particularly n/a kings or anything.

 

Yeah thats about right. 260 crank hp stock, so you're in the ball park.

 

Now if he had a npi bottom end? Different story.

 

pi heads, cams and intake? 9.5:1 comp ratio with npi bottom end right?

 

I think its 10.5 to 1 gotta back track...blak would know fo sho. Now you deck the heads and do some valve reliefs? Look out!

 

But the limit for CMC is 260rwhp i think

 

I had about 280 or so, maybe more at the crank with my 98 pi and with my 97 I have about 220 to the wheels currently...it's enough to have fun and get in trouble with. But I need multiple tiers up from get in trouble. I need more like set up the road blocks and dispatch the pursuit Lamborghini hahah. Not that extreme...but it'd be cool

 

Pi swap will be around 10-10.5:1

 

Thats what i thought, really as long as you can keep the heads and intake flowing these 2v love compression. The higher the better
