Sounds great Ian and I bet it does sound great! Is the engine at that level where it will need rebuilding every x hours?? ------------- Z3M Roadster (gone....just...but not forgotten...yet) E30 M3 (Toy) Alfa 147 (just gone) BMW 330d (new work horse) Daimler Double 6 (no idea yet) |

Ian Spill the beans on the specification! Is that figure off an engine dyno or calculated from rear wheels? Who built it? Presume it's an £8k+ jobbie! Cheers Piers ------------- piers66 |

It has been tuned on a dyno , hasn't been in the car yet , got a small leak on the sump gasket so am going to replace that before fitting it. It will be stripped in about 1000 competetive miles to be top and tailed. I built the engine myself ,I had Lester bore the ports in the head , and I blended the throats to finished it , also had a local firm do some of the engineering work for it. £8k ?? try double that .....

315bhp from a 2.5. Not bad. I bet it doesn't have much low down torque and judging by that dyno printout I'm guessing there isn't much power below 4k rpm. A proper racing engine then Good luck in the Rally. Where is it?

its in west Wales , on Brawdy army base.
Cant wait to get it in and try it , with the sequential gearbox and 5:44 diff it shouldn't be a problem keeping it on the boil ------------- www.godspeedbrakes.co.uk |

I would argue about that. He's got more bhp at 6000 than the average S14 on peak..... and I have driven barefoots car (some sort of GrpA engine with 300bhp) and that pulled CLEAN from 2000 like a train. ------------- E61 520d, slow and buzzy but my wallet likes the mpg..... |

Ian,
With that diff you will be busy on the gearbox! What next? Paddle shift? Good luck Sunday, I hope it credits itself well and gives no problems. ------------- E30 M3 Macao blue metallic Evolution 2 E39 530d Sport Auto, Aegean blue Edition, Sat Nav, TV, comms pack etc. E39 540i Auto, Sat Nav, TV, leather, luxo barge |
