Got initial reports on dyno tune sessions on my twin plug 2341cc six. We made just over 200 HP at the wheels. Best news is that we got the mid range hesitation sorted out. The car should really fly now!
I'll ave dyno sheet later this week. |

I seriously can't wait for the mud slingin thread yer gonna start comparing your dyno sheet to one from Jake Raby. Those 4 vs. 6 debates are the best (IMG:style_emoticons/default/happy11.gif) Hope to see you soon - Candlestick AX maybe? |

Those 4 vs. 6 debates are the best (IMG:style_emoticons/default/happy11.gif) Hope to see you soon - Candlestick AX maybe? Guess we could try to compare my independently conducted chassis dyno with all real systems on my car to a lab rat motor on a crank dyno done by Jake. I havent seen many independently conducted chassis dynos on Jakes motors so I'm not sure we can have much of a debate? (IMG:style_emoticons/default/biggrin.gif) Most impressive to me is that the motor is an old school six with stock 35 year old designed heads, cylinders, 2.2 liter pistons to raise compression, a real stock cooling fan and rebuilt crusty 40 mm IDA weber carbs. Pretty impressive stuff to get close to 100 HP per liter with such an old Porsche design - no fancy expensive redsigned systems or heads, toothless fans, computerizes FI, etc. Just good old Porsche engineering tweaked to make some additional HP over stock 911 S specs. We already know this motor can take abuse as it has about twenty 25 minute track sessions without single signficant issue. We had a couple of scares, but they have all been minor issues unrelated to mechanicals of the motor (fried wire harness and loose screws in the carbs - fortunately those two didnt happen at the same time or we may have had a Porsche roast) I have to credit GD Racing http://www.gdracing.com/ for building such a great motor. Gary knows his stuff when it comes to building cost effective 911 motors. And Schatz and Krum for their chassis tuning expertise. http://www.schatzandkrum.com/ |
