Pretty straightforward.. I was just seeing if any of you lucky mofo's had a chance to get a baseline dyno yet, I'm excited to see the results! Please post up some results, and if you havent been to the dyno yet you better get your asses down there.

Nobody....

I don't have a sheet, but I remember the reps I was speaking with saying it got 334rwhp.

WOW... 80 hp drivetrain loss...!?!?!? that Fooking 8 speed slush box must SUCK power............. or butt?

doesn't that seem like alot of power to lose between crank & wheels for a 2 wheel drive car?...like 30 or so too much...?

1/4 mile trap speeds indicate the engine should be underrated at 416hp and closer to 430-450bhp. Something definately doesn't add up if they are only putting down 334rwhp and trapping what they do...

technically its only a slushbox in first gear

GOOD POINT..

just like toyota underated the supra tt as well...

You are correct... the transmission is locked together from 2nd gear onwards.

Dyno

I contacted K&N in Riverside and am hoping to take my car to them to get some dyno runs done on it, in exchange for a prototype K&N air intake systems installed onto my IS-F. I'll try to post the before and after results. Hopefully they will accept my vehicle submission. I'll keep everyone posted.

334rwhp thats weak.stock 335 dyno 300rwhp

 

[shift_red]

there are a lot vids on youtube for the IS-F mainly during shows, i remember seeing one of them saying that they were seeing 400hp on the wheels......cant find it though

 

[is300cb]

Im really curious to see what it puts down. My V is rated at 400 and it put down 330 bone stock, which is entirely common but at the same time really pissed me off. It doesnt take much to free up the power though w/ v8's, I picked up 50rwhp with catted long tube headers, intake, exhaust and a tune. Im sure the IS-F will be able to have some nice gains with similar additions.

Dynos differ a LOT. Can't go by ONE dyno. My first dyno - dyno dynamics totally stock car gave me a result of 239 rear wheel HP. BUT, I still manage a 13.2 in the 1/4 bone stock. So, I'm scratching my head... so I go another dyno - a dynomax or something and suddenly I have 20 more HP at 259. Some IS350 guys say they have close to 270 hp stock on their dynos.

Ok so if IS350's are getting 13.3 1/4 consistantly, why is it so hard to believe that a car with over 100 more horsepower and much quicker shifts can't get a 12.6- 12.8 1/4 mile....and it is still an automatic, and automatics generally lose 20% on the drivetrain, 416HP - 20% is almost 334rwhp.

Stock 335i dyno is not even close to 300rwhp, get your facts right.

???? They make 300hp at the crank...0% drive train loss, I don't think so.

We actually have an IS350 in Virginia running 12.88 1/4 mile

with Joe Z Intake, Tanabe Exhaust, Secondary Cats removed & front seat removed for the run..

are you kidding me? since when does a car has 0% drive train loss? :fool:

its called under rating guys...

you guys are fkn daft,UNDER RATED ,just like my IS250MT
