This engine was initially built naturally aspirated so my compression is roughly 10:1, and I am running E85 fuel (103-108 octane).  I have a steel balanced and stroked crank with probe domed pistons and h-beam rods.  I am hoping the lower end holds up.  I put the truck on the dyno tonight before I went home so I am hoping to get it tuned tomorow and have a few dyno pulls.  We will stay at 8 psi boost for now.  If the engine holds up I now that number will increase.  There is no such thing as Enough Power!!! 

0.7 Bar boost, big intercooler and flattop pistons. Fuel octane is european standard 99.





Y-Block handles a lot more advance than 5.0L.

We ran our Y with 32 deg total at dyno few years ago. Here is the link if you haven't seen it yet.

And that was with 99 octane gasoline.

Hey everyone just giving an update on the truck.  We got trained in on the dyno last week but my truck wasn't running quite right so I didn't make any pulls.  I decided to completely redo my power and grounds.  I had a lot of interferance, mainly with my MSD 6AL box.  I ran my wires directly to the battery and my pickup has never ran this smooth.  I am really hoping to get it tuned friday and maybe make a few power pulls.  I learned alot about wheel horse power last week.  I think most people don't understand what it takes to get power to the ground.  (I know I didn't).  We did a lot of the training with my buddies 94 Viper and it put 240 wheel/hp, and 275 lb/ft of torque.  I am curious what my truck will do.  I am going to removed the waste gate spring when we tune it to get it tuned perfect without any boost and then put the spring back in.  We will do a few pulls with spring removed so I can get you some results finally.  Was just wondering I anyone is running boost what kind of timing you are using.  The guy that trained us has tuned alot of engines and he compared it to a 5.0l with a turbo and suggested nothing over 22 degrees advance and then take away one degree per pound of boost.  Any suggestions would be great.  To take a quick look at our Aussie toy go to robisrepair.com and click on the performance tab.

When you,re using that aussie dyno, better turn it rightside up!!

Dyno showed up late friday.  I couldn't take it I pulled my engine and installed the new cam.  I also installed my new high stall converter.  I got a chance to take a peak in my engine and was amazed at how clean E85 burns.  My valves are spotless and tops of my pistons are nice and clean.  I had to order some new titanium header wrap so that should be here tomorow.  I will take pics of the completed project and post them tomorow.  Chris will be up from Kentucky on friday and saturday to train us on the dyno.  By the end of the weekend I should have some dyno sheets on my turbocharged y-block.  Cannot wait. 

Any news or updates?

Well my cam showed up today but we decided to wait because our dyno is sitting in customs in California.  Will be here at the end of the month.  We decided to dyno my engine with the current cam and fuel injection to see the results of the different cam and turbo upgrade.  Figured everyone would enjoy some dyno results.  I am also curious what that enine will do naturally aspirated too.  Right now I have an Isky cam #F300 with fuel injection and is now running on E85.  Don't worry everyone I will have some dyno results soon and the turbo results.  I have also updated my throttle body.  Now have on a FAST EFI 1000cfm throttle body.  It is equipped with LS7 injectors that are modified to 95 lb injectors.  We will not have a problem jacking up the fuel pressure now either.  It also opened up the top of the throttle body so there will be no restriction from the fuel injectors like the precious one.  Can't wait to get you all some results.

I hope your cam shows up soon! An early Christmas present would be nice! Keep us posted.

Hey everyone just wanted to update you on my project.  Decided to redo my fuel system.  My injectors we don't believe will be sufficient for what we want.  Plus they are a big restriction in the throttle body.  I am going to get a 2 inch spacer plate and weld in four injector bosses.  Then get four 1600cc injectors.  That way we can run higher fuel pressure and cut out the middle of the thottle body.  We will use the Commander 950 to fire the injectors, we will just batch fire them and they will be underneath throttle plates now.  Will just have to manufacture the fuel rails.  That's what's new now.
