Good to see such coverage of E30 M3s in the mag - still feel there is room for regular E30 M3 tuning advice somewhere. I know we cover stuff on engines, suspensions etc on various forums on an ad hoc basis, but how about someone getting a guide together. I, for one, would be willing to help, but unfortunately engine building isn't my strong point...or suspension ..or... Thoughts? |

Yep was a fund day out. Shame everybody went at 12!
I found it a little bit cheaky ( to say the least) from a red M3 to claim only 250 bhp well knowing the car was putting down 300 on a other Dyno before..... Also wondering if a trip up to Powerstation is adding bhp while'u'drive? (read the EWOK article and compare power figures from this board and the Powerstation run) uups..... |

Yeah, Powerstations correction factors are a bit optimistic. EWOK 154BHP at wheels (uncorrected) makes 236bhp at the fly (uncorrcted) 82BHP LOSS. My arse. Steve |

As has been discussed ad nauseum it's difficult to compare across dynos on different days - but I'll still post what my lastest figure is when I get it tomorrow. What I thought interesting is that there is a pretty big jump between standard cars & those "lightly modded".

Steve, I agree. That car isn't even making 200BHP in my opinion. Assuming that all wheel bearings, rear tracking, brakes, tyres etc, etc are in good condition and correct it will only be loosing 40-45BHP through the transmission (as both my SE and Evo2 does and my Europameister did 6 years ago) I havn't bothered to buy the mag, but was Ewok put in the same feature as this dyno day? |

QUOTE] Uwe me and Kev met this car and owner at Croft. He claimed 300 bhp and Kevs could not possibly get 300 with a distributor. Well kev's car overtook it and out dragged it on the back straight. His excuse was kev had larger cams, so what if he did, but the claim was Kev did not have 300 BHP. |

Dessies car..
I have not driven it myself but I do know the engine builder very well. It has all the right bits added to a very strong engine and has been assembled correctly. 300 is very optimistic though.. watching the car in action at Cadwell from behind in a well driven stock 2.3 it could not pull away. I also noticed everyone on his tail at Croft complaining that the car was fast on the straights but holding them up through the twisties.. I would say that the car makes a good solid useable 265 or thereabouts. Nick |

I've seen his dyno polt from Powerstation and it made 220 odd at the wheels. (Can't check 'cause British Airways has my laptop anmongst other stuff that they lost for me on friday) But the Flywheel figure was something like 316BHP! Good old Powerstaion corrections.

Just to add a little fuel to the fire, here are my latest figures: At 7800 rpm 192 bhp at wheels, 237 bhp "flywheel" At 5500 rpm 175lbft torque Weirdly (as it is meant to have 284/276 combo) still pulling strong at 8k... Done at Chipwizards, Rochdale. |

Did I read the engine tuning section right because it looks like they are
not happy with there alpha N and are going to ditch it in favour of a stand alone ECU? |

Thats stupid, there are lots of guys here that have had the AN fitted and are totally happy with it, I suspect Power Station has talked them into thier Motec? I wouldn't bother with that either and go for the Dastek Uni-Q if I was them. But then - They seem to know better, so who am I to say? |

Also noticed the 'loss' figure was like 60bhp on the before and 80 odd bhp
on the after. So its easy to pick up 20hp in that case. If i remember right the difference between wheel figures was like 6bhp ! EDIT: also I belive the Catcams 283 is pretty much the same as a BMW 264 or 272 (can't remember which) if measured in the same way. Edited by 215DMX |

Dave, the wheel figures are not corrected. It is only once the losses have been added that the correction is done.
Thinking about it... How can you add a correction factor to a transmission loss where that loss is not affected by the tempreture/barometric conditions? I'll have to lok in to that... Steve |

One thing worth mentioning before this thread dies
Whether or not a car can pull away from another on a track mostly depends on how well the cars are being driven just because a powerful car doesn't pull away doesn't mean it hasn't got the claimed power speed through the turns has a very big effect on speed on the straights you can never assume that 2 drivers have equal ability |

I bought my car from him and had a look at his...(excuse the rubbish phone pics) He claimed 300bhp to me, he certainly hasnt cut short spending money on it. Although i have to say, i saw it at Brands a few months ago and it was getting seriously hassled by most the M3's, including Martin's standard 195. |
