I have a revup as well, and I dyno'd 241.9 bone stock. Doug Stewart from Crawford(crawford cats, plenum, headers, etc) claims the 6MT drivetrain loss is closer to 17%.

If that's the case, then my bone stock dyno of ~242 = 291.5hp, which is awefully close to the revised revup crank numbers of 293hp, so I totally buy the 17% figure.

BTW - that would put his crank at 316.2hp/297.47tq.

 

I dont think calculating it by a certain % of drivetrain loss is very accurate.. Especially since the power that each motor makes from the factory varies from car to car...

 

Well, since your a customer of Jeremy's, and Jeremy loves to brag about how many of his cars are racers, its time for you to take that car to the track.

 

Actually, at 17% his Hp rating would be 307.05. A gain of 9Hp.

However, different dyno runs, different time, condition, and etc. Comparing different dyno results from each other doesn't always add up right.

I think the OP needs a serious tune, because the gains he got from all his mods is not very significant.

 

not only that each dyno will read different. The only reason ur numbers are impressive is because the operator says that stock 6mts put down near 240whp on his dyno.

 

I do need to run the 1/4, but it has been raining a lot lately.. I plan on going tommorow or early next week.

 

Yea, I am pleased with a 22whp gain from my current mods..I had a 330Ci with the same mods basically plus a chip and I gained only 16whp.

 

also one thing that i have noticed is that people with DC sport headers are always seeing some nice gains.

 

Wow, stockies puttin' out 235-240rwhp... was that specifically '05 6MT sedans??? when i was at Technosquare they told me stock '03 5AT sedan's where puttin' down around 210 to the wheels and i pulled 247rwhp on a heat soaked engine(after mods/reflash & tune).

 

Nice man!

Bone stock with my 5at i put down 217.6whp

 

My bone stock dyno was 241/210. My wife's bone stock dyno for her 04 5AT, on the same dyno 30 minutes later was 215hp/208tq.

 

yeah, they told me the 5AT looses a lot more to the wheels than the 6MT. they also told me i needed new one step colder plugs and they'd be good for another 10hp or so. so, on a better day i could see some better numbers.

 

How would colder plugs help a NA engine?

 

but yeah, if i had a 6MT i'd pull some better numbers BUT i'm doin' pretty good to the crank, i guess.

 

hotter engine, colder plugs work better... i know i was like "WHAAAT???" at first too BUT even the Infiniti users manual says you can go one step colder if you: 1) live in a warmer area or 2) stay in higher RPMs. 2 for 2 for me.
