This chart might help give you and idea .





So if you accelerate in 2nd gear NA - the g forces will be identical to accelerating in 3rd gear in a turbo .
Note the slight lag as the turbo spools up from low rpm .


NB : corrected for US gearing ....

 

wow, nice..how did you get that n/a log?

 

/\ was tuning a friends car a few days ago .

 

nice..i say time for a video!

 

/\ you mean N/A vs turbo from a roll ?

 

*******..

good luck with parts from usa!!

hate you..

good job!!!

That's awesome. I do similar time measurements when I mess with my boost, but I never got a chance to do it NA to see how drastic the change is.

 

Thankyou .... I think

now get your *** into gear and get FId

 

 

been there done that. Kane and i made a 4th gear pull from some stupid low rpm/speed. he was braking from upper rpms before i even really got moving. i couldnt have kept up with him if i had started in 2nd gear.

he has the 3071 MM special

 

is that the one you did a night ? - as i remember you can't see much on that ....

 

no, day/evening time. lighting/visibility isnt the issue, its scale/range. he left me so quickly, the only way to have had a better perspective would have been a third chase car with the camera. Which consequently would need to be able to keep up with Kane's more or less. Or a helicopter shot...

you cant see much, because with the camera mounted on my dash, once he was more than a few dozen yards ahead of me - you loose all sense of depth. the only thing that will compensate for that is: very nice camera equipment, elevation of camera angle, perpendicular camera angle(assuming you could keep both vehicle in the shot

 

just need video camera , another car , two extra people and ..................... a helicopter and i'll do it .

 

hehe

 

lol nice! make me want to get FI now.....

 

Good times.... I never thought of the camera issues personally. Makes some sense I guess.

The problem is that you want the perspective to be from the NA RX8 (which most users know how that "feels") to compare to the unknown (in this case turbo-ed car.) To do that you need a really good way to capture the full depth of the movement.

PS - Paul, compared to those days..... my car is on a whole new level. Wish you were around to let you drive it.

btw, funny how that fits for both of you guys.

and thanks for you service for our country.. get back home safe!!!!!!!!

 

Meet me at the Annapolis boat show (Columbus Day 2010) or the house around the same time and I MIGHT give you my keys too.... for some rum.

Anyone who has met me knows that I very seldom say things that I am not willing to follow through on.

 

Just thought of another way to look at it . Label the y axis $ spent over time and you have another good comparison of how it feels to own a turbo .

 

That's cool Brettus. I'd see a plot the turbo in 2nd gear included on the graph, just to see the increase in the slope of the line.

 

/\ can hardly do 2nd - too much wheelspin

managed to find a 2nd gear run for you . Probably was at a slightly lower psi than the 3rd gear run but you can get the idea .

 

Last bit, add in gearing, so you show the starting and ending MPH's.....

 

your going to be in town. oct 11?

i very do trust you word on several levels.. got questions..

what is this silly thing you call rum?

beers

 

u should have a footnote that the y axis also is how many miles in 10k increments as to when u can expect the engine to blow up... j/k

 

mysql posted some stuff a year or two ago showing time/speed comparisons based purely on known math(meaning it doesnt take 1st gear traction into account). It was impressive how much faster 300whp is than stock. very impressive. I think most people who come here wanted to make power dont really know what driving a car with that kind of power/weight ratio is like
