Comp cams stage 3 gains

[Scarlett5.0]

What should a 5.0 with boss manifold long tubes and catted x and jlt cold air on e85 with comp cams stage 3 be makin power wise?

 

[nosscort]

At least 460-475rwhp

Might as well get some custom grind cams for the price the comps are. Was looking into cams for my build but not sure if i will bother now.

At least 460-475rwhp

Id side with this maybe less?? Idk! But i know the cats and JLT will take away from your potential.

 

[boduke0220]

At least 460-475rwhp

at the absolute minimum. really 490-520 depending on tune, weather etc. guy on fb, Ronnie Reynolds ( works at rev auto) has comp stage 3s, cj intake, lt etc. made 525rw

 

[corysmach1]

490-500.

2012 Mustang Boss 302 with Comp Stage 3 Cams - Dyno Pull - YouTube

I think same rough mods as the OP and made 470rwhp. Now lets factor in the fact hes got Cats & Not Boss heads sooo im gonna say and guess 455-465rwhp.

I made 434 on E85 with Boss IM and NO LONGTUBES. Stage 3 cams with no phasers or lockouts and longtubes id expect 490-500.....add CJ setup 520-525.

Who did your tune? Whats your intake setup look like? Is this a GT or Boss?

You'll make anywhere from 350 to 550. A dyno is ONLY a tuning tool & every one of them will read differently.

I made 551 on a mustang dyno

Here's the dyno

Like we all mentioned before.. GET A NEW TUNER.. that graph looks like a heartbeat monitor.. Also you mentioned before that the tuner you use or used does not tune 11+ 5.0's and only does Lsx based vehicles and it's obvious haw bad that graph looks bud..

All dyno's are different. 500 whp under 7500 rpm with a 302 is a difficult thing to achieve.. I hit 467 at 7300 on my cj setup on a mustang dyno and i'm too scared to spin it higher.. it wants more rpm though.

Example.. at 400 flywheel tq the 4.5L 458 Ferrari italia speciale needs 14:1 compression, direct injection, and 9000 RPM to make 597 crank HP. multiply that by 0.85 to convert to rwhp and that's 507 rwhp.

Are we saying our coyote makes more power than a Ferrari 458 speciale, at far less rpm, with much lower compression, and similar displacement?

JPC informed me to see over 500 the heads need porting as well.

 

[Bignasty321]

whats up

Whats up Enrique! !!!! Its nate u can drop ur car off at my house, ill take it for a spin and ill let u know what my butt dyno says. Its just a tool so its not 100 percent accurate....

On the real all u need is to get the curves good ans fluid and number dont really matter much. U will see 475 at most, cats need to go. Too . Hit me up when ghe next meet is

Sounds about right... Merica

I'm going to Eddie at addiction Motorsports on Saturday

You mean you made 451...

Are you still running stock heads? Are the cams already installed or is that stock cams with just a Boss intake? That seems a tad bit high for a Mustang Dyno, but like I said earlier, every dyno is different & the settings in it could be different than what would be normally used.

455 +/- 10
