707 HP and 714 TQ from the motor out of the TurboKits.com C43 test mule! We crushed our goals and probably should rename the turbo upgrades from the TK650s to the TK700! LOL
Here is the data. Enjoy!

I would venture a guess, bigger low pressure and high pressure pumps. stock ones just won't have that much left in them.
Mod list updated! We had to add some of the products to our site to make the links work properly!

Yes, they do call them the heart breaker DYNO. LOL. It is the same DYNO we’ve been using for over 15 years, we have 1000s of runs on it with various project cars, trucks, etc. It's up at ECS Performance in South Windsor. I remember when they first got it and put it into the ground. Been a lot of late nights and long days on that baby! We were pleasantly surprised tho, as our goal was purely to break the 500whp mark, so to hit the numbers we did was icing on the cake!

Impressive results! Never seen anyone upgrading the camshaft magnets - that's new and definitely interesting. Also great that even without fuel rail (like the one from InfiniteAutowerks) you guys got to this kind of HP!
Wondering about reliability, I believe @jimmykoutoulas got hairline crack at the bottom end around this HP figure. He had upgraded rods and pistons (everything else was pretty much the same), which as we see here perhaps is not the weak spot of this engine if the software is great!

Yeah the 28 PSI was definitely a "Glory Run" to show what the turbos are capable of, we would suggest a 22-24 PSI set up for the street and keeping it right around 500 WHP. Hoping reliability will be solid at those #s!
That is kind of sus to my engineering mind.
No pictures and vague description a hairline where "some bolts are".
I would really want to see the crack and the fix that was done to pin it before actually calling the block weak.
I have a block in my shop and I don't see any obvious weak spots around the crank area.
And you bolt a pretty stout oilpan in there too.
