Turbo Duster gets crazy on the street, blows up on the dyno. Great Depression Racing
Blow out 2 cylinders (the Copper O rings on the Cometic headgasket) on the
Dyno. Also bend the
crankshaft. First Dyno
pass (600+) fails to record. Car does 446whp on 4 out of 6 cylinders on the
2nd pull. You can see the entire coolant system empty itself during the 2nd
Dyno pass, plus some
weird ground wire catching fire (stupid OEM wire that was 10 feet long when
it only needed to be 3 inches long, no wonder Dodge is having troubles the
last 20 years).
This was the 2009 Nissan Dyno day Event. Won for most HP
even though motor was blown but obviously the Junkyard is not a Nissan.
The street pulls the night before included hitting 24 pounds of Boost twice (accidentally) without adjusting
the air/fuel ratios which probably lead to the crankshaft starting to bend.
Fixed the Boost controller and
worked from 9 psi up to 19. 18psi on the Dyno. Chase car is a 50 trim turbocharged VW Jetta on 15 pounds of Boost nick named the "Stangbanger" for
keeping up with his friend's Twinscrew 331ci AFR heads stroker Mustang.
550+whp Roll Racing in Vegas. The Junkyard vs a modded Cummins. Great Depression Racing
Cummin's is owned by friend and he actually towed the car down to Vegas to
go racing. We missed the tech inspection so we decided to play around and
get some frustration out.
This is the last time the built low compression motor was used. Motor was
inspected and had some damage on a piston from a spark plug failure and I
didnt feel like polishing up the piston and continuing to use the low
compression motor when I had a perfectly good bone stock 140hp Dodge
Caravan 6g72 motor sitting in my driveway that just needed a turbo system bolted to it.
Car did 516whp on 20psi at the Dyno but on the street the same
wastegate setting makes 24-25 pounds of Boost and gets VERY hairy over 100mph.
Missle Test Road 1st-3rd Spinning Drag Radials (The Junkyard's beginning). Great Depression Racing
Testing out VHT (Trackbite brand) applied to a test road while using drag
radials. Failed to hook up in 3rd gear even though the car was on minimum
Boost (6psi). Probably better to
spray the VHT out ahead of the car because doing a burnout through the
puddle didnt seem to help the next time we went down the road (not in
video). Trackbite does work at the track on slicks. Just spray on the tires
are you are pushing the car through the staging lanes. Slipped 2 clutch
discs before upgrading to a dual diaphragm pressure plate.
Copper wire + MLS headgasket. Fake O ring with no machine work. Great Depression Racing
Remove strands of copper from an electrical wire (.010-.020" thick
strands). Superglue to the OEM fire ring of your MLS gasket. .012" strand
compressed to .004" thick on this headgasket. used a .022 thick wire on my
current headgasket but had a small oil leak which may be caused by the
thicker O ring. Copper Spray the gasket when you are done.
This was done on a used headgasket as a test.
384whp turbo Duster vs 442whp Nissan SR20VET (variable cam), Torque wins. Great Depression Racing
Coheeds GT3076 powered Sentra on 17 to 22 pounds of Boost vs the precision 6765 powered Junkyard
and its clogged fuel filter limiting Boost to 13 psi. Coheed couldnt understand how
he lost the race until he looked at the torque numbers at his friends Dyno shop and how wide
the powerband is. He actually called his friend to open up the Dyno shop to prove the car
couldn't run higher Boost and was
out of fuel. First organized fun run against a very fast car. So since then
he spent a lot of time trying to widen his powerband and has enjoyed the

Engine compression ratio and displacement calculation
11th part of the Oldsmobile 455 marine engine build. The worked over
cylinder heads are looked at in this video. Timing marks, compression and
displacement are also looked at in this video. If you want to skip right to
the math go to 6:18 in the video. Thanks for watching.
Forced Induction - Supercharger vs. Turbo Charger
This video was made to describe in moderate detail the differences between
Superchargers and turbo Chargers, as well as describing the
components, advantages, and disadvantages to each. Complementing the
speaking track is a slideshow of related pictures and videos. I hope this
video helps some of you curious up and coming mechanics to better
understand methods of forced induction. Please comment maturely, and
