LT1 Vs 5.0 Opinions

[traxiii]

I liked the LS motors for what they can make NA. I really wish the Coyote could reach 600whp NA :(

If Jon Kaase can make 721hp out of a NA Mod. Motor I'm sure he could make 600hp with a Coyote in his sleep. :ford:

600 rwhp would cost big $ out of a Coyote, ESPECIALLY if Jon was investing his time.

LS's can hit that number w/ garage builds.

With 427+ cubic inches. The LS7 is the only one I've seen reach 600+ with stock displacement.

...ok?

 

[DivineStrike]

Lol yea, where's our own 351 stroker for our coyote?

 

[Nataphen]

I'm just saying that without increasing displacement significantly on an LS1/2/3, it's going to max out right around 500-530, which is about the same for the Coyote. I like both engines, I'm just making sure people are understanding that displacement is where the LS has to make up for its relatively low tech.

 

[DivineStrike]

It doesn't change what they can make out of modding the motor.

 

[Nataphen]

No, but it's not that easy either. For bolt-ons and a tune, which is all the majority does, they're pretty even. When you start pulling the engine and building a short block, you're talking about a chunk of time and money either way.

That's where the differentiation between the two exists...that's what this thread's about, right? Did I miss something? Limiting the variables to bolt ons and tunes is inadequate for this discussion.

Your wish has been granted. Many have already made 600rwhp while being N/A. Port the heads, aggressive cams, CobraJet intake, 12.5:1 compression, 3.700 bore and a nice set of long tube headers. E85 will be a must......

 

[Nataphen]

They've made 600+ bhp, but not whp. I wouldn't say "many" have done it either.

That's right, but making it sound simple and saying that the 5.0 making huge power is so difficult is what I was talking about. It's not easy to make 600whp on either of them unless you have an LS7. That's all I was getting at.

JPC/RGR put 550rwhp in their 318ci Coyote that ran 9.8's at over 135mph naturally aspirated. I've seen a 14:1 Coyote build running race fuel but it failed to put up an impressive number due to issues that I couldn't find.

On the corvette forums I don't recall seeing any head/cam LT1's going much over 550 RWHP. Heads, cam, headers, tune, and install in one thread was ~$8,000 and went to ~520 HP (from a ~430 baseline).

Not sure what it would take to get a Coyote to 520 HP naturally aspirated, or if it is even possible. Certainly it would require high RPMs, since the Coyote doesn't have the displacement for that kind of power at low RPMs. Given that the Voodoo will probably be making close to that at the crank, it does seem like it might be tough to get the Coyote to make that much at the wheels. You're looking at 8000 RPM at least.

Not too familiar with some of these builds referenced above, but to me it seems like the Coyote is at a disadvantage due to the lower displacement. Seems like modding the engine to allow the RPM necessary to hit that power level is going to be very involved.

Heads, cams, intake, and headers will get the Coyote to 500-530whp like I was saying earlier. E85 helps a little, but it's not necessary to make that power. The stock motor will spin to 8000 no problem. On a ported Boss intake manifold, I'm shifting at 7800, and holding peak power from 6300-7700. They will rev easily, and hold up as well. All I have is the Boss IM, Airaid cold air, catless x pipe, E85, and a custom tune.

I think of the coyote as a FI motor but I loved boost anyway it's fun the small block is a old school naturally aspirated work of art all in its own perfected over years and years of racing with the traditional small block I still think it wins in the NA category
