Started the big project hope to have finished in a week or so. Thought I might share a few pics...

Looks interesting.

What kind of motor set-up? What are your power goals?

 

now that would be a good canidate for the sequential setup

let us know the progress.

What turbos are you using? A/R ratio, I plan on using a T70 with a .68 housing. Just wandered what a person would use with twins?

Tuff question.... I dont want to answer yet... Sometimes goals and reality are way different... But I will keep you posted on reality!

I am running the STS Methanol injection and will play around with the boost and see what I can get out of it.



I currently or should I say, I was running a 260 hp two stage nitrogen pushed Nitrous set up. I will have to see how this turbo system works out and decide how much nitrous, if any, never mind...... how much nitrous I will use with the turbo set up.


As usual thanks for any comments, questions or suggestion

 

Nice setup and some great fabrication! Would you like some free help with the site? The pics are a big large and it's kinda hard to see what you have going on. A unique setup like that deserves some decent web space. Not criticizing...just offering some help.

 

Added a few more pics in case anyone is interested on the progress..

 

Looks very good at this point.

 

What type of oil cooler?Earl's maybe?
What fan?

 

Looks nice.

Think a ground scoop might give more air flow than a fan?

 

interesting setup


that cam really doesnt look optimal for a turbo setup.

 

Agreed I will probably change it once I get everything dialed in.
