Caddy

 

Reading the comments, I see that someone was implying that a class action lawsuit is starting up against Ford for the RX-8's hp discrepancy. Anyone know anything about that?

 

i want in this suit no im just joking i still love my car!~

 

Almost every car maker does. Lets face it, car makers measure hp at the engine, not at the wheels where it counts.

You have to read through their bull **** sometimes to get to the truth.

 

but they are saying even taking that into consideration it still appears overstated

 

I think the problem here is a combination of slight (maybe 15 hp) over rating of the CTS-V engine and an under-rating of the LS6 engine in the Z06 Vette. Believe it or not sometimes car companies actually under-rate their engines. LS6 engines, when tested on a bench dyno, usually test closer to 425 hp. BMW is notorious for under-rating their standard series engines but not the engines for the "M" series cars.

So what we have is a ~385 hp CTS.

If this crap keeps up all of the car companies are going to revert to the old R-R method of rating their engine power as "adequate".

 

Well the caddy is still just as fast (if not faster) than a 400 (394)hp ///M5...so whats the problem?

 

yeah by my math(and that's not necesarrily good ) 15% losses on 400hp would put them at 340rwhp. from the numbers posted i figure they are seeing on the dynos between 19% and 23% losses compared to my 15% figure. that certainly seems correct to me in relation to the dynos used. like it was said above they are looking at a measly 10hp extra loss between the engine and and the dyno results. nothing to scream about.

 

Maybe they need the "M" flash :D

 

LOL ^^^

 

Didn't Racing Beat get 217 crank H.P. on the chasis dyno. And that was with a K&N that they state makes 7 H.P. so were talking about 211 crank H.P. Their dyno could be off but damn a 27 H.P. or 13% difference.

 

I would kind of be surprised if the CTS-V was making more than 4 or 5 hp less than 400. GM has always notoriously underated the L's, LT's, and LS's. Also, there was little technical change in the CTS-V version of the LS-6 engine. Then again, now that I think about it, they did retune it to be smoother, which could cost alot of power. All I know is that my half LS-1 / half LS-6 Z28 made alot more than the 310hp that they claimed it did from the factory .

Also, I smoked a new M3 four nights ago, so I believe it when you say that they may overrate those engines. Then again, I'm also pushing 400hp

 

more HP posts.... i thought it was over....

 

Does anyone have a link to brake dyno that shows better than 215-220HP at the crank for the 8 yet?

I want to believe .
