  1. I love my Goodyear Eagle F1's, I feel so confident cornering in them (that could just be my super awesome E30 suspension though), even in the wet but in saying that before them I only ever ran GT-Radials Champiros, so huge difference.

    Yeah, brilliant tyre for the money..........trouble is now they are made in China.(Mine German made.)


  2. Hey Graham( Apex), been a few E30 Touring conversions in the UK with the 6 cyl M3 engine. Saw one for sale on Pistonheads for 6000 pounds, complete rebuild including brakes etc, cost a small fortune to build, if you know someone over there get them to bring it back under the exemptions.......just a thought.

    Have you seen the complete M3 engine/box/pedals/ etc on tradeyou?? 8 odd grand.


  3. Well not wanting to appear a maths geek...

    ... but an 18% **loss** would see you dividing the 214hp by either 0.82 (for 18%) or 0.75 (for 25%).

    In which case 25% would be spot on for Brent's cars.

    I just took the pwr figure & added + 20% on the calculator, your way is prob more accurate, it still doesn't stack up though.....to say you have 25% loss on a manual 214hp car isn't right......say you measure 300hp @ wheels, divide by .75 gives 400hp@ flywheel, take same car with 250hp@ wheels divide by .75=333hp@ flywheel, 400hp car looses 100hp drivetrain, 333 hp car looses 83hp drivetrain.


  4. both my e28 with m5 engine and e36 3L m3 do about 160kw at gavins place . also similer results with e34 540i .

    all rated at the factoy with 286 hp at the fly wheel

    That shows how the factory figures are the best possible, those pwr figures don't come close Brent..........................160kw x 1.34 =214 hp + 18% (manual)=252hp or + 25%= 267 hp or +30% =278 hp, the losses are nowhere near that so the factory figures are theoretical when you select the best possible blueprinted new engine.

    E46 M3...250hp @ wheels, where did the other 90+ HP go??


  5. $25k mmmmmmm........maybe Alpina E30 C2 2.7, must be last of the M Tec2

    Alpina E34 B10 3.5

    Alpina E28 B10 3.5 must be last of the E28

    BMW E30 2.5ltr M convertible, must be the last built...full factory Mtec 2, full bubble leather. (200 built of this special one) Not really interested in convertibles only this one for nostalgia.

    All manual......... + all must have full factory bodykit...prob won't get the E28 now under 25k.


  6. Apparently Dyno Dynamics is on the conservative side so maybe a little more than the 18% mentioned above.

    250hp is badass especially given its only on 6psi. As previously mentioned my 2002 M10 made 102hp on the same dyno, and was a factory "130hp" engine (in good condition and pretty low km).

    Factory HP is the best engine selected with little or no ancilliaries, real world is nowhere close unless you strike a brilliant engine.

  7. Your losses with manual gearbox/drivetrain approx 18%, could be slightly more but you have to be realistic.

    Be good to see your setup, the tuning is the hard part, takes TIME to do it properly.

    300+HP@ flywheel or take the engine out and put it on a bench dyno.


  8. Well guys I haven't managed to find a copy of this down here in Napier. Has anyone bought it and read the 540i/6 article? If it's good I'd be v keen to get hold of a copy.

    If I could trouble an Auckland member to perhaps grab one for me I'll happily reimburse. Am passing through (very quickly) this weekend too.

    Cheers

    Si

    Will shoot up the the road to my bookie & have a look Simon, haven't seen that copy around in Auck yet.They are well behind for BMW Car, if you ever need a place to crash in Auck let me know, you can stop in here.

    Nothing impressive. Bone stock m60b40 through an auto. Just thought I'd throw this up for a comparison since I had the dyno chart handy.

    In fake numbers it is:

    158KW

    300NM

    Thats a TOP result running an auto.................this is my dyno chart.post-1048-1224477391_thumb.jpg

    Stock 4ltr V8 Vs 3.4ltr M30( custom fuel/timing map) ......20kw+ @ wheels.
