Wow a 7% correction factor is pretty healthy. Why is it soo lazy? What are you running for a turbo?

I'm not up on the correction factor thing. What does it do ?

Turbo is a 14w/g H1C with a 60mm wheel. W/G set to 38psi.

Not sure why it's lazy. Could it be the dyno ? or the operator driving the truck ?

The correction factor added 7% to what your truck actually made that day in that location. Correction factors are designed for naturaly aspirated cars and are intended to make numbers from diffrent places compareable. Usually if the correction factor is more than 4% then it must be at high altitude, and that correction factor is bogus on a turbo engine because they don't lose as much power at altitude as a naturaly aspirated motor does. As for the lazy the only thing I can think of was how were they measuring rpms?

I had a long discussion about this with John P this weekend. He wa his train of thinking. He said he used to not take CF's seriously. Then he took his drag truck to denver and lost a full second in the 1/4. Also he said that even though we have a turbo we are still putting the same volume of air into teh motor but thes is less oxygen in that same amount of volume from the altitude. He said there should still be a CF, if its as givng as the gassers that he does not know. I dont know what way to think on it.

Mike also said that n/a vs. forced induction does not effect the CF. Its all about what the avalible oxygen in teh air is (and humidity).

I know this last weekend the NHRA was at sea level running and last weekend they were in Denver. All the teams kept saying alltitude does not effect the blown cars as much as the pro stockers. I know it does slow them down but the pro stockers seam to really be on the short end. I know the blown cars will run a different pulley count to speed up the blower. Maybe that is where they are making up the difference so the effect is counteracted.

All things being equal the correct Correction factor for elevation on a turbo diesel is about 1% per 1,000ft of elevation. So in Denver a CF of 5% would be pretty accurate.

what would you add in for temp and humidity? our correction on NC on Daves dyno was 13%-15% seemed REAL high.

Well the 93 went on the rollers.
6X16's, 16 cm housing, 60 GDS wheel, fuel screw 3 turns out from max, light starwheel settings, smoke screw all the way out, M+H M2 fuel pin, piston lift pump, stock timming, stock 386 spring, no ksb hotwire, stock downpipe and transfer case pipe, rag with 4.10's. Ran in direct.

The run was 301 hp and 731 torque. No idea on corrected or not. ( that is greek to me ). Its a Mustang Dyno with Powerdine control unit. ( also greek to me ).

Max power was at 2400 rpm's and max torque was at 1900 rpm's.

Rich, that's pretty good! 8) Now put a 366 in it, bump the timing and do it again. ;)

Just enough power to break everything behind the crankshaft.

I've been goofing around on vacation this week and managed to get a slot in the local dyno . ...

Still working on it. ;)

Nice numbers and very nice HP curve, still above 400 horse at 4k+. Impressive. Is there any correction factor?
