500whp to trap 119? Say what?

Something ain't right there. Which headers did you get, who tuned your car, kooks or you didn't do it right.

What intake? JLT, K&N, BBK are crap.

Exhaust after headers is kind of hard to mess up unless you got shitty headers and messing up o2 readings and fouling them

There is more power in the intake side of these cars then the exhaust side. Exhausts only real gains are from the x pipe. Headers help a little and so does a nice catback... but its not substantial. That being said... there would ONLY ever be a full exhaust on my car.

What they are is a up to date high tech 32v vvt high compression v8 engine making decent power and geared very aggressively. They should run good.
Expected Doug response

Would you expect a a high compression aggressively geared v8 not tot run good?

I was more talking about your first few lines of that post.

What is so aggressive about a 3.15 rear gear on a 27" tire? The 1st gear of the auto trans? That is about it... even then it is like a 4.1 rear geared 4l60e car, and with a 7000+ RPM shift point, not aggressive at all. Geared according to power band would be a more correct statement. "Proper".. NOT aggressive.

You need to do some more reading little guy .. you are talking to people who KNOW better.

@ the "high compression" too... Poor little man talking about static compression numbers with no cam data to make sense of that useless number.

Maybe he is talking about 3.73s?

Yea a track pack option.. yet they still run about the same as the autos. Go figure. So much for the "aggressive gearing".

I had the CJ intake, CJ Tb and ford's intake. Aed tuned ,Kooks mid length headers , and their X pipe. The headers and X pipe made the car sound badass I loved it. Most of the biggest seat of the pants feel came from the intake and tune. Now my driveshaft did help out down low. When I did get the car on a dyno it was 102 degrees out lol

Damn, you had the best of everything.. pretty sure that heat is what dropped your numbers. Bet it rolled out hard.

O it shocked a lot of people. Hell it even impressed me after the CJ swap lol. First thing I always heard beating other cars is what type of FI you got. Then when you raise the hood they are like wtf.

I'm running 29* of timing, I made 395whp stock with aed tune. Seems low to me. I now have a airaid intake and retuned for maf calibration, now this damn thing pulls hard.. not sure what it's making now

You're a ****** idiot......no 2 ways about that.

A 4.10 geared 4L60 is pretty aggressive gearing. 11:1 compression is pretty high. Not race car high....but high for a stock engine. High enough for them to reap benefit from race/e85 type fuels. No static compression is not useless data. It seems to be one of the most useful pieces of data when describing a engine. More proof of you being a idiot.

I think the CJ is overrated for a stock head cam coyote. Seems like it shines best on a Boss car.

For me anyways, seemed like a smoothed out boss manifold and Airaid cai was more efficient than the CJ, monoblade and 5in intake.

Just stop typing. Wow! It is painfully obvious why you stick to bolt ons. You have no clue what these numbers actually mean when you see them.

A 4.1 geared 4l60 is not aggressive for a motor that revs to 7000+.. That gear compliments the Coyote/6r80 just right, doesn't peak until 6500 STOCK. It would be aggressive in a stock auto LT1 that falls off at 5500 RPM. It would be real aggressive with a stock L98/700r4 combo. We are not talking about those though are we? We are talking about a motor that needs more RPM because of its smaller displacement to make HP/torque. It's geared accordingly. Only a fool would compare it to larger motors that make power lower in the RPM range. So I am not surprised at your comment

Static compression is a useless figure in determining the performance of an engine. It is only useful when calculating target dynamic compression, and where you want theoretical DC for octane requirements. Dynamic compression is a more useful number, but still requires engine VE (volumetric efficiency) to be at 100% to calculate and draw comparisons between engines. VE changes with RPM, cam, heads, intake etc. IVC event dictates theoretical DC. Since the 5.0 has TiVCT its actual dynamic compression varies.

Without knowing any of the above, you have no idea what that 11:1 SC ratio even means to that particular engine. You just look ******* dumb, and uneducated on the topic this site is based on.

The FTW purple and C85 that you see record setting runs made on would benefit ANY modern performance V8. They are a oxygenated ethanol fuel blend. They carry ingrediants that when burned release oxygen into the combustion chamber.. it has nothing to do with compression being high. More proof of how stupid you are.

Boss was supposed to come with cobra jet cams and manifold, but there were production issues.

But there is only about a 10 hp difference between manifolds.

you can port and smooth out a boss manifold and it will flow and make as much power as a cobra jet manifold

Yeah WTB found the CJ had no gains at all at the track over a boss intake
