Todd took the twin turbo to the drag strip.... faster trap speed than a Veyron

Incredible car thx for the post Hacker
Once it hooks up it comes on like a freight train
60' really needs work it looks like the car is losing at least .5 and should easily find 9s once the launch is found. The car will need a certified driver at that trap
... btw tire spin is a good thing if it eliminates bog at launch (too much traction at the wrong time hurts)

The turbo guys on Street Outlaws rev it holding the car with the brake until the light say go. That spins up the turbo and gives it umph out of the box. The trick is where to hold it back to. They also use boost controllers that set max boost by both gear and rpm to keep wheel spin down in the lower gears.

Wow. 150 mph trap speed is typical for cars that run very low 9 second quarter mile times (for most cars). Some even dip into the 8.90's with that kind of trap speed.....very cool. When he hits the beans as hard up front as he is on the back end, this thing is gonna set a very special E.T.
Edit: Not that nearly 10 flat isn't already phenomenal....

Impressive to say the least. I have ridden shotgun in a mid 10 second Dodge Dart death sled and the acceleration is brutal. Nice to go even quicker in a posh ride.

Very impressive!!
Congrats to you guys.
I know the feeling on the launch. Hard to not break stuff. Hoping to get mine well into the 10 this year.
Might go to a lower elevation to try.
That is some serious mph! !

I don't think Todd's goal for this endeavor is low et. My guess is he is looking for a legal safe venue where he can air it out and test his engine development and the ability of the 928 platform to withstand huge horsepower under "reasonable street type loads." If his goal was ET driven I think the car would already have a powerglide and ford nine inch solid axle rear under it.

He dissected the 928 (Mercedes) automatic and was blown away by the quality, same goes for the PSD. He simply cannot believe these parts came installed in an "assembly line" production car.
Don't get me started on the engine. He's "shopped around" various 928 engine parts to top engine builders who could not believe parts like the crankshaft came in a factory production car. The heads? He will go on and on for days at how superior the heads are to almost anything else he's found.
Todd has studied and dissected pistons and heads from 911 GT2 / and GT3's donated from race teams he's done work for.
He has dissected the heads from 2 liter 4-bangers that put out 600+hp, Supra motors to see why they are so fast, the Coyote motor to see what made it tick.... If word gets out some engine is apart at the shop he's never seen, off he goes with his measuring tools to see something new and hopefully learn a trick or two.
Todd doesn't just toss parts at a car and see what happens, everything is carefully studied, calculated and executed.
Bottom line, the more he digs, the more he's convinced the 928 as a whole is one of the most perfectly executed automobiles in history. He knows it's not perfect, no car will be, but you need a good starting point.
Something Todd says every-time I talk to him: "The world may never fully appreciate what went into designing and building the 928"
Take for example the work he put into the ring & pinion:

The fact that this car runs, drives, and handles like a stock 928 while being capable of going 150mph down the 1/4 is what he wants...just with an ET to match. Dumping in a powerglide and a 9" Ford would totally change the driving dynamics of the car.....so why start with a 928 then?

Its the reality of this project that will not be fully realized.
The fact is that people always think that its the large steps, or the big chunks of a project that make it go so well and work like this (and work like it has for many years for Todd).
Its not. Its the details this man sees. Its the STOP THINK and THEN do part of all this. Not slapping **** together at 3am in the rain "just to get it done". That is where the horrible reputation for "tuners" or "car guys" in our own circle and others come from - people break stuff and complain because they never stopped to think like Todd does.
There are only a few guys in the world that are doing this sort of stuff, and they all take different directions.

Hell no I like what he is doing. My point is given the horsepower this engine makes the chassis and drivetrain are going to be hugely limiting factors. If he were to put slicks on the car what would explode first? Half shafts, torque tube? I always wondered how long the drivetrain would hold up to that kind of beating with a stock powerplant!

My vote in the dead pool would be the torque tube shaft, but Greg's got them made out of stronger stuff (300M), or Todd could probably just whittle one out of whatever he deems better.

One part of the tuning that he spent a considerable amount of time is the shift maps. The fine details of what the engine is doing for the milliseconds it takes to complete a shift. These fine points go a long ways to keep a drive-train together.
I'm not saying it's indestructible (neither would he) but Todd doesn't live by the common thought process of "Let's break it to see where the limit is" since it doesn't really work that way and those who tune in such a way, rarely figure out what the real problem is or how to solve it.
Honestly, I'm worried about the CV joints themselves more than anything.
Speaking of whittling...... Years ago when he could not buy the perfect stroke crankshaft for his motorcycle he started to make one by hand. It's 1/4 of the way finished sitting in the corner of his garage. He had a change of heart and went a different direction.
When I say Todd had a change of heart...... it was probably like Doc in Back To The Future slipping in the shower and seeing the Flux Capacitor. Some days I swear that character was based on Todd.
