What's in a Harrop stage 3 kit?



.

 

4 into 1 headers high flow cats 3 inch pro extreme exhaust with factory bi-modal, otr and dyno tune

 

What do you mean by an accurate dyno

 

People love to say that dyno results are over-flated. If that's the case there must be a conspiracy across providers because all 375/385 flywheel kilowatt packs deliver roughly the same figures on the dyno regardless of who does it, around 285-305 at the wheels. I'm sure they're all equally wrong and duaned knows the one guy who has an accurate dyno.

 

How's the sound out of that system Corz75? Is it the deep sound of the walky exhaust or the snarly type more like standard?

 

It sounds heaps better than standard a lot deeper and louder. Sounds similar to the walkinshaw. Really quiet with bi-modal on.

 

LS it!

 

LS3
556.3hp / 414.8kW @ 6500rpm
498.0lbft / 675.2Nm @ 5000rpm

Coyote
510.4hp / 380.6kW @ 7600rpm
398.4lbft / 540.2Nm @ 5400rpm


LS3 Cam
231 intake – 247 exhaust
0.617 intake lift – 0.624 exhaust lift

That's my kind of cam, a nice smallish medium size.

It's a pity they didn’t show the curve under 3500rpm as the LS3 was making around 425lbft / 576Nm by then.

Yeah. It's not just the peaks hey. The LS destroyed the Coyote down low too. Everywhere along and under the curve actually.

 

Most of the build cost (parts) added nothing to power or torque. LSA crank, rods etc etc.

 

Yes a lot of parts were to add strength and balance to help it rev freely and improve longevity.

I amended the torque figures I quoted @ 3500rpm in my last post as I mistakenly quoted lbft for kW.

Intetesting which Coyote engine this is as the standard spins to a 7k rpm cut off and the Boss to 7.5k rpm.

The Voodoo is a stroked Coyote bored out to 5.2l with a flat plane crank that spins up to 8k rpm.

So a 7.6k rpm cutoff is definitely a worked Coyote or Boss to some extent but doesn't represent the pinnacle of what's placed in a Mustang.

Now the Falcon's Coyote's were all blown engines which are in a different league all together to these N/A counterparts.

 

Of course Snow. But that would be a stupid comparison. Not that you were suggesting that.
That 5.2 sounds like a highly strung canine.

 

Watch "2016 Ford Mustang Shelby GT350R vs. 2015 Chevrolet Camaro Z/28 - Head 2 Head Ep. 71" on YouTube


For your automotive pleasure it's pitted against the mighty big cubes of the LS7 in the Camaro. ☺

 

Sweet. Then came the 1LE

 

Wonder what numbers a similarly built Hemi 6.4 would make?

 

I drove a Chrysler 300 SRT8 for a week not long before getting my VFII SSVR and the stock 6.4 in that feels like it has so much more low and midrange torque than the Commodore and it weighs about 200kg more. Everything else about the SSVR is better but I would take that engine for sure.

 

Probably Hellcat numbers.

 

More. But still not as vesatile or adaptable as the LS. I love my Hemi's. But the LS is a superior motor in my opinion.

 

Totally agree, beast of an engine (makes the ls feel so whimpy stock for stock) and auto 9 speed auto box - helps with all that pork.
Vf r just in another league every where else
