thanks, well I try my best, especially since I work on car professionally now



now that i think about it, maybe i can use the vacuum pot to do the oppsit when underboost to retard timing

HoLun:

That's exactly how I have my street driven blower cars set up.  I set the total timing at 30 degrees with the vacuum advance unhooked.  Gives me over 40 with the vacuum hooked up, 30 with boost.  Keep in mind that my VR blowers make no boost at cruise, if your blower makes boost at cruise, you will have no vacuum advance.

Looks like I will be going with turbocharger instead, more pipe less brackets and pullies and takes up a lot less space, I will need a set of those cross over type manifolds for that, other stuffs should be the same with supercharger set up.



going to try a single turbo first, if it wont flow enugh might have to do bi turbo.

HoLun, I have been waiting for someone to try the turbo thing using crossover mainfolds. Mummert brought up this idea in YBM a couple years ago. I have several sets of mainfolds and if you want a set let me know. You pay shipping and they are yours, just do a good write up on the install and how it works out.

You can look couple of pictures of twin turbo y-block on my website. http://www.dlc.fi/~teros/indexeng.html and there click y-block and so on... This is early stage try on what Hollow Head has done few years ago. Now the engine (not that in pictures) should be ready for the summer and to be installed in Hollow Machine.

We'll see how that works... Or how it won't

Glen, Thanks for the offer, Ted got a set for me and hes at driving distance, so I am going to pick up a set from him, I will take lots of pics of the build this time, but it wont be sereval weeks before I can start since I am still at the stage of geathing parts.



Teros- I saw you site a long time ago, thats what inspire me to use the crossover manifold, but I am going to a single turbo method for now and see if its enugh for the 292 daily driving.





Hollow Head - woha that looks like something that came out of a tank. looks cool!

Hey HoLun,

I sent a RHD ( Right Hand Drive ) Aussie manifold ( drivers side  ) to a guy in Texas who was going to twin turbo a Y block. By using the Aussie  crossover manifold ,it matches the US  drivers side crossover . That way ,you have a pair of stock forward facing manifolds .They would look real trick if you had them HPC coated ??? What sort of HP are you aiming for ? There is a 67 Mustang driving  on the street here in Brisbane with a twin turboed 302 W .It has been dynoed @837 HP and 940 ft lbs of torque .I spoke to the guy who owns the car about doing a Y block .He seems the think 600 to 700HP would be possible .???

Lon - really? I didnt know they make the manifold different on other countries, do you by chance have one laying around that you are willing to part with or know anyone that will?



I am not looking to make huge power, maybe just double to stock figures, call me a wuss, but I dont think i can handle anything with 500hp.
