Haha chris getting ideas mate?

It's a DATSUN engine, it needs nothing to hold 10 pounds boost.

Except maybe some copper stuff on the head gaskets.

Have you dyno'd it yet? Or drag raced it with this set up? Should be quite formidable! I'm dynoing my blown A15 tomorrow, and looking at trying it with nitrous next weekend. Did you need to replace any of your pistons when you overhualed it? I recall you saying it had blowby issues after you fitted the blower. If so, what slugs did you use?

rephrase of question: what have you done to the engine. < period

I rebuilt the motor with only 6k miles on it. After taking it apart I found out that it really didn't need a rebuild. The head was worn out so I rebuilt that. No new parts on the lower end. I ended up putting all the bearings back in as well as my Total Seal Piston Rings. So really my block was only dunked and dingle balled. That was it. The hatch marks in the cylinders were still there from my original build. The machinest told me to just put the thing back together. The cam is a Delta with a 278 duration. Pistons are deep dished forged. The head is ported with dual heavy springs.
The head gasket was an after market that was recommended by the machine shop. Said he wasn't sure about the boost but what the heck. I just torqued it down a few extra pounds.
I haven't drag raced it yet (season is over for the year) with this setup except for up and down the back roads around my house. I would like to video a burnout but I have no video camera.
As far as dyno'd. Not until I complete the intake. My plan is a couple of Super Bee hood scoops and run the air cleaner through the hood although I havn't got the guts to cut my hood yet.
Oh, by the way. A second inline electric fuel pump was required to keep up with the flow when the SC was turned on.
But, I tell you what, off the line with drag slicks, the supercharger and the nitrous... HOLY SH!T!!!

Oh, another thing, I recommend the New MSD StreetFire Ignition Box and MSD tach adapter.
MSD StreetFire
MSD Tach Adapter

This thing is the SH!T

The engine bay looks really tough with that purposeful-looking aluminum. Nice work.

hehe black engine bay....hides all manner of sins, nice engine was thinkin about going supercharged when i get a sunny
