ello guys

 

just got back from dyno testing the car

 

what a suprise .. 178.9bhp @6048 rpm

 

just wondered if there are different standards of measuring BHP .. same as amplifier companies use RMS & peak power

 

i noticed mine says met/hp and others have din/hp .. which one is the correct or industry standard?

 

Thanks

 

John

no idea i thought they took it at peak bhp but i may be wrong

Did they specify if it was at the wheels on at the flywheel John? Generally add 25% to wheel BHP on a manual Zed to get the flywheel figure...

 

HTH

Steve .. it was at the wheels .. the thing that i cant figure out is wozzers n/a was dyno'd @ 248 bhp but cant keep up with mine .. just seems strange if he's 70bhp up on me.. he should theoreticly slaughter me

are you saying that wozzers NA was dyno'd at 248bhp at the wheels?

yes bud .. thats what his printout reads

john u sure wozzers wasnt at the fly ??

248 at the wheels for an NA is fantastic wish mine was that good, in fact I bet theres a few TTs out there that would like a figure like that.

not 100% sure bud but even if you do the sums mine only comes to 225ish at the fly

would of thought it was much more than 225

i do belive it is a the rear wheel's.."BUT" will be checking this again at J&E

 

zxmad mine says "correction method":Standard.....peak power:248.7@5658rpm ...BY:Dynomobile LTD...

nope its roughly 25% of the bhp added which works out 222.5.. which aint bad at all considering its a 10 year old car

Most dynos will take the reading at the fly, if you have that much power in an NA (lighter, different gear ratios) you should be blowing TTs away daily.

wozzer .. mines got a correction .. it says SAE J 1349 (5/85) what ever that means lol

i am faster than some TT "but" only to 100/110 and then they're pulling away,,so it's all low down...

248bhp will be at the fly, otherwise your looking at 330'ish at the fly which would be a 100bhp increase and the most powerfull NA VG30DE in the world ;)

 

 

Still, both are very good figures. The wifes NA is complely standard, would be interested to see what figure it puts out, and then try out some of the basic mods (induction, decat, catback, headers, chip..etc)

25% who gave you that figure?? more like 15% for manual RWD car, 4WD cars have a loss of about 25% but not a chance for our cars ;)

I was told by a tuner it is 20% loss for a rear wheel drive car, and 15% loss for a front wheel drive car.

i think 15% poss upto 18% would be max to work it out

 

tbh most rolling roads actually read at the wheels then they convert it to fly which i never understand?? lol

I was basing it on info from this thread Mike. Happy to be corrected though...

HOW ABOUT WE ALL WAIT FOR j&e AND SORT IT OUT THEN....... :D
