Guest Andrew Report post Posted June 27, 2004 For the first installment.. the weight of my car - tommorow at 1 oclock it will see the dyno. The weight was taken with: A full tank of gas approx 50 kg of fuel and my car runs.. 2 very light Jamex seats.. no rear seats.. no sound deadning under back seats and no sound deadning in boot and WITH the spare wheel. A grand total of 1070 kg done at the north shore city dump. Not bad aye.. Tommorow on the dyno we'll try for 100 rwkW and 240 rwNm torque but i'm not that hopeful .. i'm running 96 and its noticeable how motronic caps the performance to reduce knock.. i'll dyno it with 98 also next week.

Carl 3 Report post Posted June 28, 2004 Curiously, is there an easy way to reduce some unnecessary weight without degrading ride comfort??? Quote Share this post Link to post Share on other sites
Guest Andrew Report post Posted June 28, 2004 Curiously, is there an easy way to reduce some unnecessary weight without degrading ride comfort??? Probably not.......I love road noise, petrol tank noise, fuel pump noise, gearbox noise, diff noise.. ahh all the great things I couldn't hear before.

Guest Andrew Report post Posted June 28, 2004 i love those nosies to(windows down next best thing ) i would love to see some pics of ur car from wat iv read it is impresive I went out to snap some with it mint clean the other day - bastard camera kept complaining batts were flat. Next nice day i'll take some - .. it looks pretty much just like a stock clean orange e30. Quote Share this post Link to post Share on other sites
Carl 3 Report post Posted June 28, 2004 Looks obviously can be deceiving though I'd be interested to hear how loud your car is from the inside, i'd also like to see some pics. I'll be taking a few this weekend I could image, next week will be a bit of a pic-fest. Quote Share this post Link to post Share on other sites

Grant 4 Report post Posted June 28, 2004 My car is lighter than that with all the sound deadening and back seats Your engine is significantly lighter though.Power to weight, Andrews will easily out perform your 318. For a 325i engined car (with a full tank of gas), Andrews is really really light. Quote Share this post Link to post Share on other sites

For a 325i engined car (with a full tank of gas), Andrews is really really light. According to owners manual My car weighs 1010kg and a 325i is around 1200kg I think? So Andrew has done pretty well to shave off at least 100Kg with pretty minor stuff really. And I know I wont have a hope in a straight line, even my mere 60Kg weight advantage isn't enough for double the horsepower. Other reason my car is light other than engine is no electrics and no power steer (similar to andrews) Andrew what are your 0 - 100 times? just using a bodgy stopwatch method or something i just want a rough idea I wonder what weight I could get my car down to???

Even so i'm sure my power/weight ratio will be twice as good lol. Quote Share this post Link to post Share on other sites

I'm not even close to triple figure kilowatts. What do you think yours will make at the flywheel? I also say rip out all your interior. What does a track car need carpet, radio, door cards for?

Guest Andrew Report post Posted June 30, 2004 Well we had it on the dyno: A few things.. the RPM meter on Bellars dyno wouldn't work - so we couldn't measure torque.. and we couldn't put any of these figures against a RPM. Now for the result 92 kW. This is MUCH below what the motor builder expected of 110 - 120 kW. And who wants to take a guess at the reason for this - thats right.. Moronic can't deal with the modified engine properly. It doesn't open the injectors long enough - everything leans out and we lose power. Its possible I don't have the correct cam in there also. Not being able to measure torque is stupid - because this car pulls so much harder than the average 325.. a shame.. i reckon its making 240 - 250 Nm. You can see on the graph how its meant to be a lot higher. Oh well - thats 2 cars on here with modified m20s that have the power capped by moronic - Grants and mine are both the quickest ones on here and don't have the ECU to match. Anyway.. this summer Link time for me and probably Grant also. You can see how when the power drops the AFR graphs goes the wrong way - up = lean .. it should be heading down.

318i Turbo 0 Report post Posted June 30, 2004 92kw at the rear wheels is about 115-120hp-ish at the rear wheels, a standard 325i should hav about 140hp at rear wheels, something weird is going on that cant b right Quote Share this post Link to post Share on other sites

Dynos are tuning devices only. I don't think you'll find a 325 that makes more than 100 kW on Bellars dyno. Quote Share this post Link to post Share on other sites
318i Turbo 0 Report post Posted June 30, 2004 drivetrain loss is about 15-20%, im planing on going to a dyno in the next week or so b4 i start toying around with it, most dynos should be very simlar with there results, dynos work by timing to get there result it is time, speed, rpm etc etc that are calculatored to get the power output but they are neva always accurat Quote Share this post Link to post Share on other sites
