1990 bmw 325i se whats the bhp

12 Answers


makes about 100 horses on the wheels ....depending on the spec. maybe 110


A bone stock 1991 Honda CRX SI Makes 107 flywheel HP in a 1.6 litre four cylinder. It's unlikely that a 3.0 straight 6 cylinder BMW produces comparative horsepower. The 1990 Taurus SHO 3.0 produced 220 at the flywheel. I'd recheck those numbers for accuracy.


hahaha its 168bhp @ 5500rpm so about 18% loss in drive train... errr 138hp to the wheels. lol.


WHOOMP! There it is! If David said it; and he did...count on it as a reliable piece of intel! The other guy is WRONG!


Hardly wrong ...... Let me put things into perspective here. The only real power that counts and means anything is the power available at the wheels...... Drive train power loos for a rear wheel drive car is in the region of 25% simply due to the fact that Gearbox and diff are seperate pieces. Having said that ...... an E36 M3 makes roughly about 145-150 horses AT THE WHEELS. Hence my initial figure of 100 at the wheels is probably still a little generous. To any one that is into motor sport seriously wheel horse power is the only measure. Flywheel horse power means nothing if you have no idea how efficiently your car puts it down.


You're preaching to the choir. I took parasatic loss into consideration when reading your posts; I'm sure David did too. Since there is not a very accurate way of getting precise HP numbers in absence of a dyno, I stated flywheel HP numbers. David's estimate was a fair and reasonable're was a bit much I think.


I've dynoed hundreds of 325's and other BMW's, ts what our workshop specializes me when I say 100 is what they make in standard form.


25% loss is still not 100hp... im no beamer lover by any means but i loose 18.8% in my mustang from a engine power testing to the final wheel dyno run... 318.1 flywheel hp to 261.24rwhp... i was suprised by it and i would be more suprised if a BMW was at least not on par with that... Im suprised to see the 325i producing so little... i think i might familiarize myself more with thier drivetrains ive not been very bothered... just for fun would torque 'squareness' affect the overall % loss by chance??? that could be a interesting study (im 400ftlbs of tq) and most of it is there from 2200rpm and it tops at about 4250rpm...


ok to put things into perspective here .... Torque on a larger capacity motor such as a V8 like the one in your mustang is available lower down where in the smaller motor a little more RPM is needed. The other factor that we can argue till we're about blue in the face is that no 2 dynamometers are the same. I have an E30 BMW (view my profile for details) that makes 600HP on the wheels on our dyno ..... Its made as much as 800 on others .....figures differ from dyno to dyno. We've made sure that the dyno we use is calibrated at all times and True wheel horse power for a 325 is about 100-110 depending on the condition of the engine. As I said earlier an M3 E36 is rated by the manufacturer between 209-229 KW(depending on spec ....euro spec being the higher) but the TRUE wheel horse power is only about 125KW ..... Than there is the Brittish measure that we can use to further confuse our selves here .... KW, HP, BHP True usable horse power ....Fly wheel power ....... BLEH ....... you can make a million horses and the car can still be slow


100WHP?? for a 325i? is the e90 model... Id like to believe it but... *shurgs Maybe you are being generous... but what about weight and transmission?


weight means nothing when it comes to measuring WHP. The trasnmission is a manual one -5 spd. as I said ....depending on spec you looking close between 90 and 100
