bmw dyno day result
Discussion
Been a while since i last stuck a post up but been flat out with work and with the dodgy weather lately i havent had much time to do anything to my car atall
Anyway today was a really good one,
Went to the dyno meet at DS automotives in aylesbury.was a good chance to meet a few new faces and also saw some very nice looking cars,
Was a bit worried when mine was rolled onto the rollers,hearing your car hit 7000 rpm when your not doing it is a bit worrying :?
Anyway,I managed to hit 216.2bhp and that is basically down to just a gruppeM so to say im happy with how she is performing is an understatement.Also my peak torque worked out to be just under 240!
was told the engine is very healthy and pretty much bang on,will be getting a remap very soon now,hoping to hit the 220s without having to change the manifold.
Here are a few bad pics off my fone :?

thats right mate, i think its 193bhp or around that mark.
193bhp for a 328. Interestingly the 325 had just only one bhp less. The 328's significant performance gain over the 325 was down to the engine being stroked out from 2.5 to 2.8 generating significantly more torque in the process... if only one extra bhp!Anyway... I'll get my anorak
^^ ok mate if you say so ..^^well get onto everyone else who had there car dyno`ed at the meet and tell them that there figures are wrong too,i ran along side Evos and other 328i`s putting down good ballpark bhp`s so had a fair few cars to compare mine to,the figures are correct,The engine had a remap but before i took hold of it and before i fitted the gruppeM and iridium plugs so obviously needs a new one and may of made some difference,There where standard 328i`s putting down around between 190 and 200 so i really dont see how there is anything wrong with the dyno readings.
I always get told my car pulls very well for the minor workings it has done and it stands its ground along side many cars you wouldnt think it could.
Theres always one who comes out with the comment"the dyno figures must be wrong".
I dont actually care as you cant put the performance into practice on the road,its just nice to know i have a healthy motor.
And yes the operator was quite suprised and was told i would see near if not bang on 200bhp with a live remap.

yeah it revs all the way until the limiter but is no point as peak power was made well before then and the operator could see that so didnt bother to go any further,this is the problem with the M52 and standard manifold,other guys there the the bbtb conversion and manifold saw it peak slightly later and higher Bhp readings,I might consider fitting it at later date but for now im happy.
Do tell.so would you say the bhp reading is looking to be correct?must say it was bloody warm in there but anyway,yes of course i understand things can be wrong on the dyno but there was around 18 other cars also running on the day,many of the owners are very clued up and some of the mods that have been carried out are just great on there cars,many of the owners have had there cars dynoed before on other dynos and was saying that there figures where pretty bang on to other dyno read outs that they have had done in the past so i just find it hard to see that my car was the only one that had data inputed wrongly and the figures being wrong,the operator was suprised and said the engine seemed very strong so maybe iv just got a good`un.
im happy with that figure whatever.
Its all a bit of fun,and im just happy my motors still going strong

Had my 328 RR'd last summer completely standard and on the first run came back with figures you described this was due to it spinning up on the rollers!!
Quick clean of the rollers and it came back with standard figures just a thought?
Also why was it done in 3rd is it not more normal to do it in 4th?
Regardless of what it is or isnt pushing out loks lke a lovely example

3rd is the correct gear on Dyno Dynamics dynos.Quick clean of the rollers and it came back with standard figures just a thought?

And you won't get wheel spin on these rollers at that power.

I had my 328i dyno'd at DSA a few months back. Mine is completely standard bar removal of the baffle in the airbox, and it came back with 207.6bhp and 240 ft lb torque, with peak power at 5k rpm.
There were no other E36s on that day to compare it with, but there were a bunch of E28s there all putting out circa book figures.
I don't know if it's accurate or not (although I'll admit the torque figure is somewhat....optimistic), but it certainly feels 200bhp fast.
