between, your engine looks interesting, the color contrasts well with the black exterior.
Is it possible to have some information on what setup you have ?
thanks
Ali

The difference in driving is a whole nother ball game!!!![burnout](https://rennlist.com/forums/graemlins/burnout.gif)
Great thread and very refreshing.. let's keep it going!
Here is another, David Hawkin's VERY clean GTS with one of my "prototype" Blackbirds..(BTW Mike, they are 3.5" also, so gains should be similar)

Thanks for the kind words.
The engine is an 85-86 block, as well as heads/cams that have mild porting and a S4 intake. I'm using 951 forged pistons with custom forged rods from Pauter and a 5.0 crank with the cross drilling mod. In addition I have a mid mounted T-67 DBB water cooled Precision turbo that has custom plumbing done by John Kuhn. And I am also running custom inter-coolers designed by John. Fueling is done through the stock management system that has been Shark Tuned by John, along with some goodies from John Speake (SuperMaf and dual MAP sensor) using 36lb Marren Racing fuel injectors and a Bosch 044 fuel pump with a modified in tank pickup. There is also a BEG rising rate fuel pressure regulator to tip in some additional fuel pressure on the top end. The current tune was done at 8psi resulting in 434RWHP/488RWTQ. I have an electronic boost control and this fall we will turn up the screw to 12psi and re-tune the car. It's been A LOT of work however I am starting to see light...shhhhhh not going to 'curse' myself by thinking I'm almost there

Abby/DR - it was a 2 stage powder coat. Shop laid down silver first, baked it on, then topped it with the blue - before baking stage 2, they wiped the raised letters, which show the silver underneath. The pics don't really do it justice - it popped!

Thanks for the information Abby
I like the setup. To me if Porsche wanted to make a turbo 928, it would have looked similar under neat the hood.
