Hey race fans,
Sometime in the future I plan on running a 2.7 six over my four banger. Anyone have any idea about where my weight will be after the -6? I'm I looking at 50lbs? 100lbs? More?? I could drop some weight from the car still. Want to get that HP to weight just right!! Theres a large group in NASA (ST4) I think I could fit into perfectly If I get the math correct.

So at 2450lbs I need to make 218HP average at the wheels
So at the flywheel thats around 255-260HP. If I take in account a 15% drop from flywheel to the wheels. Think I'm asking to much from a mag case? Hell, I'm at 160HP (wheels) with my -4 mag engine now. |

The 3.6 will be the heaviest and need some more specialized conversion parts than the smaller motors but any engine around 250hp will need lots of cooling. You are also getting to the point where you will want/need a 915 trans since unlike the street, you wont be gentle. I wouldn't even begin to build a 250+ hp engine on a mag case. The 2.0's I was referring to are built on sand cast alum cases. Our 962 is built on an aluminum turbo 3.0 case. Close to 800hp on the dyno. |

(IMG:style_emoticons/default/huh.gif) I'd think 40-50 HP per cylinder shouldn't be that far out of reach. As far as cooling goes, I have a large oil cooler and a trans cooler already set-up. I'd have to check my notes but I believe we never went above 210 degrees in Fl at a 14hour race. The trans cooler is still untested. A 915 trans is in my future too. I just need to get my dad to part with it! (IMG:style_emoticons/default/driving.gif) |
