HOW MUCH POWER IS YOUR E30 PUSHING?

[e30bmlover]

If it's a Mac F1 or something, then yeah!!

lmao. in response to the question '' how much power '' i would have to say.......... NOT ENOUGH.

[bootyman]

Would defo be worth going to Pod this year if that pole dancer is prepared to flash her packed kebab again

[blingsta]

A-tech rules guys !!! im just an unlucky turk with my motor... my turbo has just gone kaput but i will be there bigger and faster than before to promote A-tech and im sure so will a few other f/i boys.

[bootyman]

So Blingsta if i blow you away with my car packed full of ICE you'll officially come here and say otherwise?

[blingsta]

Dude, winning or losing doesnt matter, i will gladly come on here and say Bootyman beat me, but i will cross that line too, 1st or 2nd who knows?? ... maybe my turkish luck would follow me there and this time my doors might fall off.

[bootyman]

I was just joking. My engine was smoking like mad last time i drove the car so i might not even finish! lol

[M5pilot]

Booty, crisp bank note awaits you.

[bootyman]

I need it, so good. Dont dissapear on me mate

[M5pilot]

I may be a little muted these days (and I mean this literally...no voice!) but I'm not going anywhere.

Well I just got back from Janspeed in Salisbury (nice company - recommended) who put on the 6 branch (older style) [and a new control arm and the H&R Anti-roll bars less relevantly] - so the car's running the following now, if this helps OP :

E30 Zone Shop "Wild" chip
Big-bore throttle body
K&N 57i Induction Kit (Yes, Sal, it's still on there... )
6-Branch manifold

And it got 152.7bhp at the wheels and 150ish lb/ft torque.
I'm lead to believe that the wheels is 20% down on the flywheel figure - can someone confirm? If so, its 190+-bhp at the fly which rocks.

The H&R Anti-roll bars make a hell of a difference to handling by the way lads, as per the review on here by Jhonno.

Now I've got her back and she's running well - I'm well chuffed

i was told the flywheel figure is usually 10-15% higher than @the wheels but im no expert. couldnt the r/r operator work it out for you? how come some r/r'ds give a flywheel figure and others give at the wheels figures when all measure at the wheels?

[maxfield]

i got 178hp using 15% transmission loss.

152*100/85. so take a transmission loss from 100 and substitute the 85

[Turbo-Brown]

Some give a figure that's corrected to account for losses in the drive train and the tyres on the rollers, but it's just a guess at the end of the day as the losses when there's no load on the drive train are different to when there is load.

It's not a bad guess, but it's still a guess.

[JaMMi]

Yeah I was looking online just now and 15% seems to be the agreed figure to use when guessing the flywheel figure.

Most RR centres will probably give flywheel figures if they want their customers to feel better about themselves. I'm not knocking those that do... but like with stereos I prefer to use RMS figures as its more "real world"... But to be honest as soon as I had the wheel bhp I did the maths to make the number bigger straight away so they might have well as told me the flywheel guesstimate in the first place

I thought the 153lb/ft torque max was a little low? I've seen lots of "170" figures mentioned on the forum but re-looking (if its not a word it should be) thye seem to be the 2.7s and had some extra stuff done. Is 150 bhp and torque at the wheels a good figure??

[poboyis]

not really sure. ive got mine chipped with ANSA exhaust and cold air. but ive also got an aluminum flywheel which makes for more useful power. I know it spins up faster than any other 5-speed e30 ive driven with the likewise mods. id guess around 190 or so.

[Kos]

all I want to do is enjoy my car

oh ok, enjoy it

[oguz327]

2.7 fully lightened and balanced bottom end, cam, BTB and BBTB.

No idea on power as it not been RR, only 1680 miles on this build so she is still tight, expecting 200 bhp +


As far as The Pod goes ill deffo be there, last year was a blast, 15.3 in my sport last time, hoping to be quicker this year and maybe surprise a few people.

[Simon13]

shes a good 200bhp this is my safety guess Oz

my touring is around 40bhp on 5 cylinders at the moment! haha

[lance1a]

My 1988 E30 M10 B18 (316 1. is pushing about 120BHP with Mikuni/Suzuki GSX BST34 bike carbs, custom laser cut alloy manifold, Maxiflow RC 125 air filters, sytec regulator at 2 psi, D'Bilas 292 10mm lift cam, Magnacor 8.5mm competition leads and NGK Iridium plugs. Just need a free flow exhaust to complete the mods and dyno the car, but most M10 manifolds are for 2002 or e21 or LHD cars. My steering gets in the way, so I guess I'll have to cough up big bucks for a custom system. Maybe when my pension pays out then?

[m-dtech]

my m50b25 with its t3/4 hybrid turbo, megasquirt and me at the wheel.... who knows what it will run bhp wise, but i will have fun finding out what it can do !!

[siddiqi1]

E30 325i Sport

M20B25: 110k on the clock

KnN Induction with Heatshield
Scorpion Full System
Head was done at 104k

Running 169BHP at 5650bhp peak

Have a dyno but havent yet uploaded it

Good i say for an old girl

Saboor

[munky30]

m20b25: 178 on the clock... supposedly a 120k engine but thats been proven to be as believable as the claim it was a good engine.

Piper cross foam filter bollocks.

Cheap-ass 'wild' chip.

dodgy bodged HKS exhaust.

Early high comp engine on late management.

On other forums I claim 174 + 15 from the chip + 1 from the management mod. So 190 (152bhp/ton)

In reality I'll be lucky if I'm pushing 170. Probably close to 160.

Close ratio diff means I'll still lay waste to an 850 t5. proven by my ass dyno and my mates 850 t5. Thats a 225 bhp car btw.

[e30bmlover]

book is 129bhp so im guessing 115 bhp????????? shes done 112,000 so im being sceptical, i want to be pushing over 170 with the rebuilt 87 325 on facelift monotronic. i will get her dyno'd when the swap has happened and post my results.

[wullie325i]

about 15 stone at the rear wheels when i have to shove it about

[Karan]

300hp hopefully in my e30 if i can build a good shield to control IATs

[brian325i]

192bhp standard m50b25..........until my Active autowerke kit comes..then 314bhp(well thats what it says anyway) more than likely 250bhp,

[Rosc0PColtrane]

A mighty 129 bhp

[fuzzy]

the bhp and 1/4 mile figures are just for jovial bragging rights.although my touring has a decent power output i know theres plenty about with more and will happily admit to a defeat because like my car ,when you come up against something on the road you dont know what engine has been fitted or what stage of power its tuned to .to date ive not been beaten by many but i do like to try against bigger sportier cars to see how i fair against them and to give me the spur i need to tune it to the next level.
some people take it to personally. as previously said, just enjoy your car,thats what its about
im hoping to race against my mates new evo 8 this weekend and will post up the results.

Then the t5 must be fucked then.

or your mate drives like an old granny

[munky30]

850 t5 (225bhp, 1447kg) = 155bhp/ton

My heap (at a guessed 170bhp, 1245kg) = 136bhp/ton

Take into account the close gearing of my car and the long motorway gearing of his car, plus that its 10 years old and has lived on a farm all its life so is probably quite far down from 225bhp and its not so far fetched.

850 t5 has a book 1/4 mile of 15.6, not far off the 'book' 1/4 of a 325.
