Naja, sei nicht so bescheiden. Ich glaube Dein "kleines" Projekt ist hier im Forum schon vorne mit dabei und für deutsche Verhältnisse...... der TÜV lässt Grüßen . Freue mich auf Deine weiteren updates.

Well, don't be so modest. I think your "small" project is high level here in the forum and for German conditions ....... the TÜV sends his regards . Looking forward to your further updates.

First test fitting. Seems that all that measuring paid off :cool:. The billet fuel rail are a nice match. I wanted to mention that the throat of the intake runners at the head entry are almost 3 in. wide. It does not come across since there is no dimensional reference point. I am afraid that there will be some sort of fuel consumption involved here.

Every time the SLC is in the driveway it causes folks to stop by and ask questions. One in particular besides how fast, what is it, how much HP, how much does it cost etc. The question is how it will sound. All I can say as of this point is that I am trying to achieve what made me do this in the first place. Watch the video of the car that did it to me 30 years ago. 6.3 liter V8, 32 valve naturally aspirated with ITBs. 730 HP in 1989.

What can I do. I got sucked into this.
Talking to a friend about the futility of resisting our obsession, I recalled toying with Hot Wheels under the Christmas tree at five years old - my course was set. An acquaintance recalled going to his first race at Laguna around the same age, many decades later he actually now owns the car that won the IMSA race he saw that day.

We all got sucked into this.

I started on the vacuum system driving the MAP sensor. Added the ports to the ITB manifolds. The swivel push in connectors for the ITB manifolds are underway. The collector manifold was chosen to be off the shelf and is sitting under the pedestal for the ITB linkage. A side entry was machined for the MAP sensor. Instead of using hardware to secure the sensor, a slot was used to hold it in place. I opted for eight equal length tubes vs. daisy chaining them. That way I can add check vales if needed and it's smoothing out the pulsing of the signal

Stephan, well that is impressive. Reminds me of my all time favorite GTP car, the Chevy Intrepid. Used to see it race at Limerock and Watkins Glenn back in the day.

Looking at these headers is reminding me on what comes next. My new primaries are supposed to be pretty much of what is in the picture. 2" + and 32 " long, equal lenght to get max. scavenge from the exhaust system and to reduce back pressure below 38 KPa. I am glad I have nothing installed on the sides because I'll need that room now.

I finally decided on the insulation material for the coolant piping. Taking also into consideration weight savings, the idea of a surrounding enclosure from stainless or Aluminum was cancelled even if aesthetically more pleasing. A layered approach was chosen with reflective Aluminum coated fiberglass wrap as first heat reducing barrier, surrounded by a high R-Value closed cell foam to minimize heat radiation and to prevent condensation to be absorbed or to accumulate.

This is some very impressive work. Got an ETA on a start up?
Hello Dan,
It will still be a while. I was ready with the old setup in April and pondering if I should push the button. I think if I did the ITBs would not have become reality. My current agenda is to mock-up the complicated headers. In addition, the new and high HP rated radiator design has become quite involved. It needs to be taller and deeper, shrouded with larger brushless motor fans. The new dimensions are difficult to accommodate and a new front end structure is alredy forming around it on paper. I knew the new induction system will take at least six month, it looks like with everything else that snowballed it will be early next year.
