No gains with E85, Car Slow AF

[80FoxCoupe]

Coyotes don’t need/utilize cams unless you’ve heavily ported the heads, running 13:1+CR, and/or are turning 9000+rpm.

Pretty sure Holdener made 40 crank hp on a bone stock gen1 with some NSR comp cams.

See? 420hp stock. Add cams. Now you make 40hp.

Pretty sure I haven’t got a clue who or what Holdener is. At 40hp, was this average, peak or what? What and where did he lose? HP at low RPM (no biggie if it’s below shift point), TQ? Low rpm street manners?
Pretty sure there’s a few hundred low/mid 8 second stock cam coyotes too.

To be fair, that's a gen 1. There's less meat on the bone with 2 and 3 after the optimizations Ford made. Its not that you can't make power with cams on later motors, you just need to optimize other parts of the flow path further or raise rpm.

Yea, you need to go back to stock cams. I'll send you a set of stockers for your stage 3's.

I saw about a 1 - 1.5 second 60-130 increase switching to gen3 shortblock and cams. I also have my stock ones still lmao. Sounds like a claim someone would make if they want the cams haha

Bro you're so nice

 

[tdstuart]

Heard the same.
@tdstuart where do you shift at ?

Shifting around 8000. More than that and I can feel the manifold running out of steam, less than that and the car goes slower.

It’s why I’m doing my custom ported boss and bigger tb. Poor man’s cj, should flow a lot better in the higher rpm and car doesn’t have torque as it is so no losses there.

You're not interested in throwing some more gear her way? I think a set of 3.73s or whatever works with your converter would rip on your car!

 

[tdstuart]

Those are mostly tin cans lol. I like my interior, wipers, and AC lol.

I like all that stuff too. Only weight reduction I am thinking is a skinny in the front. I have 305 width tires all the way around I’m sure that’s not helping haha

Ya that will be next, or a converter. One guy on here said do the converter first. But yes I think a better diff gear (leaning towards 3.73) and a converter would help.

Converter is not going to help 60 to 130 rolls unless it is super loose like a 5 or 6K. I'd have to see a dyno sheet of your car to make an educated decision. You want it to stall at or just above torque peak.

Do the gears first, in fact do everything you are going to do, then choose a converter.

The offer on the cams stands

Ignore the people talking about the DAs. As your draggy images show, the DAs are very close between the two 91 octane runs and E85 runs (or did you add those later?). That said, a tenth quicker 60-130 is only about +0.5 mph in the 1/4 mile. That’s about a 6 hp gain in a 4000 lbs car (w/driver) and could just be variance from one run to the other and not real or actual gains. Another E85 run is showing as slower than your 91 octane run with a similar DA. Something isn’t right—you are no faster and in some cases slower on E85. Did you test the fuel? Is it truly E85?

You mean you actually read the post? Weird.

I always thought the dragy DA thing was inaccurate, but maybe it's not. If not, then OP needs to log spark timing so we can see if the e85 is being properly utilized.

It is running 30 degrees, plenty of timing for coyote heads.

My question is the VCT. Has Lund or anyone dynoed the OP's cams or is it an educated guess.

@Wengerd Performance

I'll tag Wengerd maybe he can answer the VCT question.

I'm out of ideas then. Not that I had many to begin with, lol.
