I have my stock G35 here... getting some 19s on there soon... am curious as to what would be the best way to bring the 280 stock to 300+ I don't need it to be way over 300... just 300 ballpark... just as a personal satisfaction thing

Thanks

K&N panel filter, 350Z intake tube, plenum, headers, test pipes or high-flow cats, y-pipe and a TechnoSquare ECU flash will get you solidly over 300 horsepower at the crank.

 

intake, exhaust, hi-flow cats, plenum, and TS ecu should comfortably over 300 hp. Plus, with the upgraded ecu, you'll have revs to play with. =P

Oh, if you want bang for buck, intake, plenum, hi-flow cats, pulley kit, and TS ecu(so you dont run too lean) would be easier since exhaust tends to be a little expensive.

quick question kwakman.
what do the pulley do and how much is a TS ecu?

Neffster put 246 HP to the wheels with R/T cats, a Popcharger and Ztube, and a Crawford Plenum. This translates to about 301 HP at the flywheel. Total cost, about a grand.

Hey catatafish, what do you mean 246 "at the wheel?" and 301Hp at the "flywheel"?

It seems so far that the Ztube intake and the plenum and ECU flash and highflow cats are the most recommended mods

 

There is a 17-18% loss of hp through the drive train (from the flywheel to the transmission to the wheels). Thus the 301hp at the flywheel (crank) will be reduced to 246 hp at the rear wheels.

dennis_said,

Nissan sells cars based on a 280 bhp claim. This claim is when you take the engine out of the car (without the tranny, driveshaft, wheels, etc...) and place it on an engine dyno. The crank (the shaft that sticks out of the engine) mates up to the dyno and yields a measurement 280 hp, according to Nissan.

When you put a car on a dyno jet dyno, you measure the horsepower and torque at the rear wheels. There are paracitic losses due to all of the inertia of the moving (rotating) parts, thus the rear wheel horsepower will read lower than the crank horsepower. Each brand of vehicle will have different losses.

One way to EXTRAPOLATE the crank horsepower is to dyno a completely stock G35 (same make and model is prefered) and extrapolate out the crank horsepower from the dyno's measured results. This method is somewhat crude, but is the easiest way we have of measuring crank horsepower (bhp) without a baseline dyno for comparison purposes (and even that has it's issues).

The stock G35C-6MT (at the Central FL Dyno Day) dynoed just under 230 rwhp, but according to Nissan is 280 bhp. This calculation yields a ~18% paracitic loss. [1.0 - (230 / 280)] * 100% = 18% loss.

Since the stock 6MT had an 18% paracitic loss through the drive train, take 1 / (1 - 0.18) = 1.22 and multiply this by whatever you run on the dyno (for me it was 246.4 rwhp, if I remember right) and you get ~301 bhp.

Does that make sense?

 

Great explaination, I get it neffster, thanks

Hmm.... so a 1000 dollars will get me approxamately 301 bhp (pretty much when car isn't running right?)

I kind of want 300rwhp now heheh

 

well good luck on that!

I can explain it easier......lets think in Muscle Car terms for a second.

Pretty intense formula huh, just call me baby einstein...lol
