You call that a turbo?

Is a turbo :D

Aaron has been building fast cars on his own since he was a teenager. Mostly he likes to shoot for the stars and do it on a budget. He seems to remember everything he reads and loves to race. One thing about Aaron is, he doesn't like to build anything he can't drive around. He has always driven his Nova around and has no intentions of changing that now.

He has a 1970 Nova which he ran a series of engines in, which a 454 Big Block Chevy running consistent 10.30 1/4 miles was the first engine of real note. He ran this engine for 5 years before it barfed a valve.

.....after that Aaron abandoned his idea for a newer nastier big block and decided that he wanted to move on to two of his biggest curiosities, turbos and LS series small blocks. There are many people running them across the US but no radical ones in our region.

The engine will be based on the tried and proven 5.3 liter LS series iron block from a truck.

Lashout, what's the plastic box with what looks like condensation on the porthole? Something to do with the turbo or IC?

Yea, 'coolers in the cockpit.....go figure. Follow the pipework and you'll see it!

Concrete (not plain concrete, special formula) goes into the block to increase the rigidity. Mad but true. Drag racers do it a lot, sometimes filling any spare space (cooling system is the usual candidate) with concrete.

Don't need much heat control for ~15 seconds running! :D .....hence the half fill though, so it can still be used.

in the cruise vid sounds like he is getting a lot of surge, it won't last too long like that.

It does, sounds horrible. I think its almost inevitable with such a large compressor housing and wheel, from the way it sounds its way beyond the realms of ported shrouds to fix too :(


Awesome bit of engineering though!

He took it to a chassis dyno, the Land-Sea brand dyno we used to have at our shop which is now at another shop. At the rear wheels it made 1208hp and 1057tq corrected..

The full blown racing powerglide transmission or maybe the converter is now toast so they stopped the dyno session while they were just making noise but still working. He is going to pull the trans and tear it and the converter down. He runs a Neal Chance converter and it dissembles so that you can fix it or internally inspect it. He may be able to do this tonight but not sure when the next trip back to the dyno will be.

He said, "I may go back...... It sounded great at 8500, smooth too really smooth."

Hehehe......
