Latest round of mods complete. Gonna dyno next weekend. Predictions?
I think you grossly underestimate where my car is, and with good reason, by all accounts, I should be making what most of the estimates have stated. However, that I know of, noone have done the mods that I have. Maybe because they were dubbed "unnecessary with K16's."
I can say this, Ive raced 997's and 996's that have made north of 550whp and they've lost. Ive also raced cars that trapped 127mph+ and they've lost...by a lot. With a good launch, I' know my car is a 130-132mph car in the 1/4. Which is completely unheard of with stock K16's.
If your car is making less than 600whp, I'd be happy to meet up for some fun freeway pulls. I think you will be shocked at the results.
As far as upgrading turbos? I think I'm done with modding this car. Its just way too nice of an example. Maybe, I'll look for a clapped out 996TT to go further with, but for now, I'm content.

1bar of boost you will be in the mid 400whp and thats with all of your mods.
You will be lucky to hit 125mph in 1/4.

My car with similar mods as yours, except running stock X50 K24s and 1.3 bar, ran 126 mph in the 1/4. I would be flabbergasted if you were better than 125 on the K16s. And for reference, my car made 495awhp/525awtq on a Mustang dyno. Although I am currently sitting at 4500 static elevation, and generally 6,000-7,000 DA. So my mph and dyno should be slightly better.
But I'd love to see the proof. Go do it!
Instead of worrying about dyno numbers, why not just take your car to the track? Comparing dynos generally doesn't get you much information unless it's, same car, same dyno, different mods.

If youre car is really trapping in the 130s you either have crazy weight reduction or your stock turbos were upgraded by previous owner and not disclosed... Hard to argue with the numbers, but if your car is full weight and making that power, I'd be pulling the turbos off and measuring wheels....

It takes roughly 600hp (flywheel) to propel a 3400lb car to 130mph in the 1/4.
If my car ends up making what i think it will, it confirms why cars running 125mph+ traps lose so badly during roll racing against me.

They might be terrible drivers.
It takes around 600awhp to get to 130mph looking at alot of videos.
Heres an example with billets hes still at 125mph 1/4. Roll racing and a start are two different things.

FYI. My 2003 996tt coupe weighed 3500 lbs with 1/2 tank of gas, 100% stock with subwoofer except it has heavy (previous owner purchased) 18" Victor Equipment Turismos and A GT2 clutch acc/slave conversion. I was surprised to see the 2007 Volvo S60R only weigh 3700 with junk in the trunk. This was weighed on a winery's certified scale.

If you want to prove us wrong, take your car to a drag strip. Otherwise you are just bench racing.
As a side note, I love that you are testing the full potential of the stock k16s. (if your car does indeed have stock k16s) Based on the videos of you vs. upgraded turbo 996s this seems like a stretch though.
