No clue honestly. Ive "seen" on the interwebs... numbers as high as 475whp. But I dont go by anything other then what i experience. Guy i knows boss made 447whp and so far... ive made more power then him mod for mod (under 5whp difference). I do have a higher flowing catback and a TB on him though. That could be the slight difference.
that's just wild to get those kinds of numbers out of a 302 cubic inch 5.0 liter motor. rear wheel, dyno'd...... just amazing.

no, no. the 5.0 I raced made 420 on the same dyno I made 415. I don't know evan...lol. I know the owner of the 5.0 I raced pretty well. We raced once before this and I beat him. That didn't go so well, so he went and bought the boss intake, added e85, and bought some racestars...lol and this race was the result.

it hasnt "redlined" yet. Rev limiter right now is at 7800. Curve hasnt dropped yet. I suspect it will hold steady for another 300-400rpm. Its literally straight as an arrow. I dont rev it anymore because ive already covered my entire in gear power range with flat power. No point in reving higher.
Well that's impressive, very, very impressive. I wouldn't have expected to see those kinds of number until upwards of 8Gs, like a NASCAR engine.

efficient cylinder heads my friend. Its just technology. Give it another 10 years. The new technology will make these motors look like the old stock 302s

Buddies boss in TX with lt's, catted x, cold air, mail tune, just made 415whp. Still a conservative tune. He then had it dyno tuned and gained 16whp and made over 430whp. Still stock throttle body on 93.
A lot shops have said they TB doesn't gain crap on the boss or GT. All the record.setting 5.0's and boss's still run factory TB 's.

Every dyno is different. I made 464whp.with my manual 5.0 GT with full bolt ons and 93 revving to 7800. They now have been revving the regular 5.0 to 8200 rpms with no issues. A boss engine should make least 20-25whp more then a GT both full bolt ons. A lot things depend though. Mainly who is tuning it. I have seen two full bolt on GT's make 20whp on same dyno difference. Only difference was the tune its self. They had the same setup.

Jlt cai
Boss intake
lethal off road h-pipe
flowmaster axleback
E85
AED TUNE.....makes 422/369.
The tune is very safe and the car has a lot left in it exhaust wise. I mean did people miss where this 5.0 ran door to door with the c6 making 447? The 5.0 also beat a G8 making 470-603.....the 5.0 is fast.

please do. Im not a fan of direct injection in the aspect of griming up valves. If they 100% solved that issue, then great... if not... they might be in the same boat as some of the euro guys (cylinder head tear down and cleaning) every 20k miles. If they found a way to filter the oil vapors or something.. factory catch cans maybe. Im curious to know what they did.

Your way out of line saying such things. Admit your $hits slow and move on to the garage and begin troubleshooting.

I dont understand why everyone says a H/C ls1 that makes 420whp+ should easily trap 120+ and a new bolt on 5.0 making the same power with same weight with far superior gearing cant do it unless its a gutted race car.
To me... that is NOTHING but biast opinions. Hate to say it but the MT82 puts the power down better then any Tremec in existance. They might be weaker, but there gearing is 10x that of the 6060s. That is NOT a biast opinion.
Carry on techers..

thunder - I'm not sure what your trying to say. we are not arguing mod for mod. They are saying something is wrong with my car, based on a bolt on 5.0 beat me. My point is this...
5.0 makes more power and better gears. same weight. shouldn't the 5.0 win? I think so...

Unless that guy has about 200 lbs of weight reduction, the new 5.0 Mustang should be heavier than your 4th Gen.
