Quick video of Tom Ragonetti's Fiat 850 Spider on the DynoJet. Initial pull had power at 54hp. With carb jetting changes and ignition we got it to 58.5hp. Factoring ~20% driveline loss, that would put FW hp at ~74hp. Not bad for a sub 1L engine. Pulls done to 6500 rpm.
Marc Tartaglia sent a video of his Abarth Record Monza with the engine built by Midwest-124 last year.
David Kravitz's 1978 1800cc Fiat 124 Spider on the DynoJet. 10:1 forged pistons, Croft stage 3A cams, GC triple springs, 40IDF carbs, Marelli-Plex ignition, lightend flywheel, Helix clutch, full port/polish. I just rebuilt the transmission and did some carb tuning. With driveline losses, HP comes right into about 130-135 at the flywheel.
Brian Bensen's 1986 Bertone X1/9 up and running. For those interested in the tone of the Borla exhaust.. a bit 'rorty' 🙂
David Hayes' 2L performance engine.
David Hayes' 1979 Fiat Spider 2000 performance 2L on the test stand. 10:1 cr, 43mm/37.5mm valves, Guy Croft stage 3A cams, adjustable cam gears, Helix clutch and flywheel. 123 Ignition with selectable advance curves (not Bluetooth type). Twin Weber 40 IDF carbs on Pierce manifold with EuroCarb center linkage.
Troy Navarro's performance 2L
Troy Navarro's performance 2L making varoom varoom noises on the test stand. Carbs balanced and tuned.
D.G. Stern's 1438 race engine on the stand.
D.G. Stern's 1438cc race motor on the stand. Topped off with a Pertronix Ignitor2 conversion and 0.60 ohm coil.
Due to the rotating assembly being so lightened and the compression so high, it doesn't like to idle below 1500 RPM. Too little inertia to overcome the 13:1 compression.
One of the meanest 1438's you'll ever hear.. BTW, running on CAM2 leaded race fuel.
Jim Marcotte's 2L high performance engine test run.
Jim Marcotte's high performance 2L up and running. Please pardon the rattles of the old test stand. It's been moved around a lot lately for the new location and is getting a little rickety.
Jim's engine is 10.2:1 cr, 2L head ported and chambers polished. Allison 284 Stage 2 cams. 43mm intake 37.5mm exhaust valves and Isky springs. Weber 44 IDF carbs on a opened throat and port-matched Pierce Manifolds intake. Athena MLS head gasket.
Due to Jim's flat-hood early Spider, I had to go with a low profile air filter, thus the short 15mm tall air horns with generous radius.
Miller's Mule adjustable cam gears and aluminum front crank pulley and water pump pulley. Flywheel is aluminum with steel friction insert. No clutch attached at the moment so it's a ridiculously light rotating mass.
Ignition is being handled by a Computronix block-mount trigger and twin-coil wasted spark firing system. This gives a clean look up top and gives extra hood clearance with no cam mounted distributor.
On the stand it is fitted with an early 4-2-1 cast exhaust manifold and downpipe. Jim will be fitting his long equal-length primary 4-1 header inthecar.
