Take that car to the strip.. i really want to see if it gets anything better then 11.9 @ 120 mph.

People will ague forever about Drivetrain loss percentages. I wonder why because we are talking about Chassis dynos... We dont use engine dynos. On our Chassis dyno this car made 323whp and with the mods it made 430whp. Thats 107whp gain. Thats the delta that we added to this car. The most important thing is that around 4500 rpm we added 170 ft lbs of trq! If Crank hp numbers are for some reason important to you add the delta gained to the Factory rating of the car. Any way you do the math this car is over 500 crank hp.

I think I was making closer to 600 on that day to be perfectly honest....on K16's.

 

I agree. The big, black dyno never lies.

 

600hp on stock K16's No way in hell

 

Okay...how much power does it take a full weight, AWD TT to trap 126 mph?

Let me give you a hint...Stage 4 cars (using K24's and making 600 HP) normally trap 124-125.

 

scott u had a freak run... thats was crazy... I never got 126 mph with k24s and starge4.. clutch, intakes... etc.. granted I did it on hot days... u were doen at 55 degrees or something... but still thats crazy... especially on stock k16s...

 

I know, I know...but my car was simply making some serious power at that Stage 2 level. I trapped 126, 125 a couple of times, and high 124. You simply can't argue with those trap speeds.

I also hammered an X50 car much worse than I should have for only making 500HP (vid below). My point is, K16's can maker a lot more power than people think, it just depends on the car. My car was definitely in the 600 hp range at that time...for whatever reason.

Scott, I see you made that run in December, do you remember how cold it was then?

 

How much does a full weight 996TT with driver (say 150 to 200 pounds) weigh? My guess is a minimum of 3650 pounds? 126 MPH 1/4 mile trapspeed and 126 MPH is about 570 crank HP, however those HP calculator don't assume AWD type drivetrain loss, so my guess is that to do 126 MPH in a full weight 996TT it will take about 600 HP to the flywheel.......

 

You are exactly right....

I weigh about 200 lbs with my helmet on.

 

Joe..it was a nice, crisp 55 degrees out.

But on that particular day, in those perfect conditions, at 1.1 BAR and on 100 octane fuel...those little K16's of mine were making some serious power:

By the way, all the HP calculators that say they calculate WHP are WRONG, these same calculators have been around for about 15 years (well before chassis dynos became popular) and at the time they said they calculated flywheel HP (they assume a certain drivetrain loss, my guess is ~15%). Somehow over the years tuners (probably to make their cars look better) have been quoting them as RWHP.

I don't find 600 HP to be unreasonable for the 996TT turbos maxed out as I'm sure they are larger than stock Supra turbos and those can make over 550+ HP to the crank MAXED out.

 

Correct. Jean will tell you the same thing. K16s run out of air way before then. K24s get there or there abouts. More like 550 on those...

 

Hey Scott, who did the tune on the K16`s when you trapped 126mph?
