For anyone who has FI...when people, whether tuners or general public, ask you what the horsepower is that your Z/G is pumping out, what do you quote them? The estimated crank HP or the actual RWHP?

 

people would usually tell u WHP but i dont know about FI guys

 

Most Def WHP numbers!!!!!!!!!!

 

I tell them whp and then depending on their knowledge may help them understand how to compare that with manufacturer's stated numbers.

EX: "The car has 375 horsepower at the wheel. That's basically the same as an Enzo or 750 horsepower at the crank!"

 

+1 I know average people don't have a clue about WHP. One time this kid came to me and ask about my car, when I told him I'm pushing around 360-370 he asked me why gain only 60hp over stock

 

Cause 15% crank loss is hard for folks to understand, but fast as a Ferrari is EASY .

 

Whp

 

the people who don't know much and only understand crank hp, I'll give them a crank hp ballpark estimate.

for people who understand dynos, I'll tell them a whp number and the type of dyno etc

often, I'll just tell them both ___whp which is probably around ___ crank hp

 

whp the way to go

 

i had a guy in a stock cross fire tell me he had around 368....

 

ok kinda off topic but how would one determine crank HP if they have F/I?
i always thought it because wheel HP is abt 15% less thn crank then you would get your WHP, which is 85% of your crank and well:

WHP/85%*15%+WHP= Crank HP

 

WHP.......but most FI guys tell little white lies about how much whp they really have, for example the video of that jack *** from down here in Florida with the fake blower sticking out of his 350Z hood. Thats a classic.....

 

Coach if youre talking about the Day Blue Z...THAT was classic Rice. I laughed for days.

 

Its a K&M with a rotary supercharged with a turbo and BOV and ooo... A TRAIN HORN!!!!!!!!!!!

hahaha

(some things are off of a dumb mustang "GT-R" owner...haha)

 

if its someone that has no idea wtf they are talking about i will estimate crank.... like at the bar with a noob i will just say my car has somewhere just under 650hp.

if i am talking to a car guy, i skip the BS and go straight to whp.

 

Actual RWHP

 

Yep. If it's a person that knows about cars I give them the WHP number. If they are only used to seeing power numbers on TV commercials I estimate crank.

I usually just tell people "enough to be quick".

 

if i am telling someone i say whp.. if i am comparing it to a production car.. i use crank hp

 

Hell i just say 1 billion.But in reality i just estimate crank hp unless they no what they are talking about.

 

I remember when I was on the stock motor another Z owner pulled up beside me at a traffic light and we exhanged words. He asked me how quick my Z was I said "It dyno'd 235 to the wheels" He goes "Oh yea? My Z makes 287!!"
