  • Aother day, another dyno session....

    Hi guys just thought id let you know my experiences with my car after the engine rebuild and remapping. Quite a lot had changed from the old lump including, stage 2 ported head by Grant Motorsport, oversized forged pistons and Sport Evo injectors.

    Although the engine was completed a while ago now, the final mapping on my car was completeed by shepsevo3 (Paul Shephard) over the last week.

    Final figures;-
    (Loaded)
    268.1bhp @ 7669rpm
    195.9lb ft @ 5388rpm

    The figures dont really show how flexible the car now is. I took it to Southam yesterday as its now going in for a little makeover and the pace is unbelievable. We went up the A46 from Tewkesbury and the whole trip i was grinning like a cheshire cat. It no longer feels peaky and picks up from 1500rpm in 4th or 5th with alarming pace while also being absolutely *$%!*! mental when im in the mood for a proper drive. Paul and Grant have done a fantastic job and i'd just like to say thanks for everything.

    Everytime i drive this car it does make me realise i made the right choice when picking between the usual suspects (ie Audi Quattro 20v, Porsche 968 CS, Lancia Delta Intergale, MB 190 cosworth, Subaru Impreza P1 or an Escort Cosworth) Just blody awesome..... The only problem is justifying my spending habit to the other half......

    Here are the dyno graphs and ive included an inertia run graph for the hell of it. There seems to be some ambiguity between which figure is the most accurate depending on who you speak to(which was the reason for my previous post) but Paul says loaded and to be honest i think its a more realistic figure.

    Would you tell us a bit more about your engine build? Is it still a 2.3L or close to it? In other words are the over sized pistons for a 2.3 bore or a 2.5? What compression are you running? What kind of port job is the Grant Motorsport stage two? Does it include over sized valves?

    Oh yeah, did you just remap the chip or do you have some sort of aftermarket engine management?

    Regardless of the details on the dyno (type, adjustments, etc) it looks like you have a strong engine. Congratulations.

      That is a dang strong engine.... Particularly the torque. Satisfying to drive I bet...

      I would like to know a bit more also....particularly cams used, compression, and engine management system. I am guessing the cams are more aggressive than 284/276?

      Congrats!

        Yeah i am really really chuffed. :-) The head work along with the engine refresh seems to have helped throughout the rev range and i am using Shrick 276/284 cams. I think the compression ratio is now around 11. The rest is;-
        Sport Evo green 330cc injectors
        Sport Evo valve springs
        Stage 2 Ported and polished head by Grant Motorsport
        Wossner Forged pistons (oversized)
        Wossner piston rings and gudgeon pins
        shot peaned rods
        Sport Evo oil pump
        Baffled sump
        And to finish it off a short ratio 3.64 LSD and Z4M bush kit
        Dastek Uni Q piggy back ECU and carbon airbox

          Its still a 2.3 but its using the largest pistons that Wossner sell for it. I think its about 50cc so not a great deal. I didnt want to go 2.5 at the moment due to cost. (i only wanted a head rebuild because it had a bent exhaust valve) but when Grant ook it apart it was all original internals and was looking tired so it i bit the bullet and got the lot done. The compression is around 11:1 - it think this is the culminative effect of pistons and very slight head skim (about a thou). No oversized valves, but porting on the inlets and a little on the exhausts. Grant wanted to do oversize valvs but i didnt want to go too extreme - pussy! :-). Its using the Dastek UniQ piggy back ECU in closed loop. I had the car dyno'd at a respected dyno near me before Paul and the loaded figures and it came out greater than Paul's so i think the loaded figure to be pretty accurate.

          Apologies if there seems to be errors in my reply, im not incredibly mechanically minded - all i know is its quick! :-)

            You've got that bit wrong Warren... Its not "quick", it's quick to the point you don't realise your speed untill you are high up the rev range in 5th.. before travelling very far... its insanely quick But it also has the flexability to be a pleasure to drive everyday around town for the misses to go shopping in
