naturally aspirated the engine is basically at it's full potential. the manufacturer advertised 300hp is from the engine crank, not at the rear tires. thru the process of the power being transfered thru the driveline from the engine crank to the pavement a loss of power is created. maybe my z has 360 from the engine but much less at the rear tires.

 

wu-watt has 3.9 final drive

madbomber has 4.083 final drive

 

Take it out of a car and put it on an engine stand. Then maybe you'd see 280-300HP.

 

good number for an rev up.. your looking very properly tuned.. i'll say.. i have the jw pop charger and clutch in flywheel in my 03.. no headers or exhaust.. but with those two up grades that ***** rev and runs like a mother****er.. the down shift with that drivetrain combo is stupid... i've had the set up over a year now and when im on the freeway and down shift her, boy. she chirp them tires and go... ive had some of the finest and fastes cars respect the z from what they see me do on the free ways... keep it up man...

 

A clue huh? C'mon.. I dont know what parts he's running but if the name Cosworth is in there it will be alot.. I would say 10-12k.. Am I right? Do you have a clue?

 

Nope......not a clue lol.

 

Great numbers. Probably would pick up more if you swap to the Cosworth manifold though. These numbers are not far off at all. He's got full bolt ons and a revup. Stock the dyno of a revup shows 240-250whp 43-33 whp gained is nothing unbelievable. I bet on Church's dyno he'd put out in the low 300 range.
