RE: New Engine Break In
We run a 1964 Ford Fairlane with a stroked FE block. 490 cubes. 685HP 760ft lbs torque. 1100cfm Dominator Carb. Single plain intake (big square hole!!) 12.5:1 compression. 76cc heads. Cam - .685" intake--322 duration .724" exhaust--308 duration. 104* LCA. No nitrous or stupid charger. All motor. :D Runs on 104 octane track gas. For those of you that don't know--thats WICKED for a straight motor without a power adder. Now consider we had that dynoed at 6200' altitude. And NO, thats not "corrected" for altitude. Thats ACTUAL numbers.
Ford 9" rearend that was narrowed. 43spline axles. 26x12 ET tires that fit in the stock wheelwells. 4-link rear end. Coil overs. 3.87 gears (I know--doesn't seam like enough, but all that engine torque does wonders :D) C-6 trany with manual valve body, trans brake and reverse gate shifter. 5000RPM torque converter. MDS 2-stage ignition. We launch at 4800RPM. Shift at 7800RPM. 60ft times are 1.55--1.58 seconds. Runs 10.70--10.74 seconds in the 1/4. We used to launch at 4800 and shift at 6200, but it wasn't "locked in" the torque converter long enough and we saw trans temps that we didn't like. So, we put a different cam in the motor to change the RPM range. The car used to run 11.30's. Changing the shift point and the cam took us into the high 10's :D. The launch is unfriggin' believable!! It just squats the back and and goes!! The left front tire comes up about 3" and it's GONE!! Hardest part of the whole run is letting off the gas pedal at the end. The tires only have 11psi and when you unload the suspension at the end of the track--it's pretty squirrley. Sorry. Back to airplane engines gents!! [sm=red_smile.gif] EDIT: Forgot this. The car weighs 3320lbs with ME sitting in it and 7g of fuel. It's a door-slammer with a full 12-point cage. |

Exhibition tickets aren't that cheap Pat. I do still have my old 429 that was loaded to the "gills" back in its day

Ok, many questions here, and some car stuff as well, which in the context of running in seems allowable.
Pat - I have this oil in stock, and also took pictures of the cylinder, see below. The exhaust port is clean. The little black in the head was so soft, it could be washed out with gasoline and a pig-hair brush. The engine test results are published here: http://www.prme.nl/forum/viewtopic.php?t=166 I used canisters, tuned pipe and a two chamber pitts muffler, checking plugs in between and adjusting the H- needle as required. This test was done after the engine had been run in on the MVVS 3204 canister muffler using a 24x10 Menz-S prop. This large prop was hard on cooling, but no special provisions to improve the cooling had been taken. Test CHT ranged from 140C to 200C, depending on mixture settings. For the oil, see http://www.putoline.com/en/product_d...2&catalogId=94 for info. The new MHX oil looks very promising as well, because it allows a wider mixing ratio of 1 - 4%. The RS959 that I use is primary an injector oil that can be premixed. In my oil tests at 200°C, it flashed off quite short (probably the lighter premix additives), and thereafter did not oxidise quickly, but spread out without drying out. After 20 minutes at 200C it still was quite clear and thin, and could be wiped off the test plate very easily. (Under these conditions, Castor had dried out and polimerized completely) I have been busy repairing the jug, so it can take a spark plug again. Brass tapered insert, just like they used to repair old worn out spung (?) holes in bronze canons. (the hole used for igniting the charge.) Foto included. Lesson learnt: do not check plug readings in a hot engine, but let it cool down first. The short reach plugs have so little thread length that it should be treated with a bit more respect than I did. |

My dad put a Cobra 289 into a Volvo B210 back in the late '60s. It was a total sleeper. I got my first driving license in a Chevelle SS 396.

RE: New Engine Break In
My last mod was a 400cubic inch 6 cylinder REO into a 1946 Dodge 1 1/2 ton dump. Converted to air over hyd brakes. Chev man 2 speed rear end. Still have pieces of that one.
Also did a 56 healy. Complete with 69 Camaro SS350, unibody front and my own make suspension on the Chev posi rear. Had to sell that one fast. Too much fun. My last ride in it was to deliver it to Sac. The new owner refused to drive it:D Still have the Healy running gear from that too for some unknown reason. So how does a 2 cyl fit in the palm of your hand 115 ci 2 cycle engine kick my but for over a year trying to make it a good engine? |
RE: New Engine Break In
Pe,
Thanks for that oil info. How do you think it would stand up after 12-18 hours (continuous) with cht's between 120 and 160c? Ambient operating temps from -15c to 60c. |

RE: New Engine Break In
The oil was recommended to me by a mixed track racer, whose (liquid cooled) engine had develloped hich spots with castrol racing oil. The Putoline cured that.
I have not yet long term experience with it, but asked the factory for more data, especially the 100°C viscosity. It should compare to a SAE 50-grade oil (~18 cSt), but be at least a 40-grade (12-15 cSt). The MHX type seems to be 50-grade like all top of the bill racing oils, so I asked about that oil as well. Detergency is good enough, and so is stability against oxidation and engine internal corrosion protection. |

RE: New Engine Break In
does anyone have any tuning ideas as for what will make tuning a GS260 engine easy?
