(412bhp) Standard VXR8 is 227bhp / tonne


Working off power to weight principle my 1400cc Fabia would keep up with a 6.0V8 412Hp VXR8  :grin:

Ive got a 320bhp ed30. anyone with this spec what does ur cars keep up with

A rough guide, you have 320hp and weigh about 1450kg.  So your approx 220hp/ton.  Thats the figure you need to be comparing with other cars.  Obviously it doesn't take into account gearing, but its a pretty good guide.


whats the equation you have used there Sy out of interest, just so i can work my own out  :happy2:

320hp divide 1.45 tonne = 220hp/ton  :happy2:

Power to weight doesn't take into account these 2 important factors:

Grip
Gearing

But a stg2 ED30 is similar in performance to a stock 335d or a 135/335i until around 70mph when the BM's will pull away.

This Ed.30 must have forgotten to let the BM pull away.

USA stage 3 = what we know as stg2+ (extra 35bhp and 50ftlb)

and that was an M3, not any of the BMW's I mentioned. :P

ermm yes, but:

e92 m3 = ~420bhp

335i = ~300bhp

Torque? gearing?

peak BHP is meaningless.

So with just 35bhp more that US stage 3 (Euro Stage2+) Ed.30 is putting an E92 M3 to bed from a roll, yet you think a LOT less powerful and not much lighter (50kg) 335i is going to see off the S2 Ed.30!?

335i = 300bhp / 1620kg = 185bhp per tonne
Ed.30 Stage 2 = 320bhp / 1450kg = 220 bhp per tonne

I assume torque is around the same on both above motors.

I'd love to see a 335i be able to pull away from an Ed.30 Stage 2 after 70mph; I'd then eat my hat.

After the 335i is tuned... well that's another story. :laugh:

why not buy the racelogic box that PDT is hopefully going to do a GB for, and then you will be able to measure how quick your car is in the real world, for example what is the power to weight ratio of Hurdy's car? May not be that high compared to some that could be mentioned (any ideas?) but it is pulling steady 0-60 at 3.8 seconds there aint much going to live with that in the real world. The fastest Ed30's fall down on traction but once up and running... I do believe Steve/Craig @ Stattlers will be able to tell a story regarding how a twin turbo RS4 with over 700bhp was a bit miffed that he could not pull away from the Eddie at Bruntingthorpe.. :party:

e92 M3 (246bhp per tonne) vs Tuned e92 335i (400bhp / 246bhp per tonne, 50 kg/s lighter than M3)


Think you could say they were amazingly similar.  Even though the 335i is lighter has lots more torque when tuned, the M3 still matched it.

Torque doesn't mean squat if your in the powerband.

Why does the amount of power that happens at only 1% of the RPM range make a difference to on road performance?

overlay a dyno graph from a N54 335i over an M3 and it makes over 100 ftlb of torque more through a lot of the rev range.

I'm not sure this is right, I've owned 2 x 335d's and 2 x ED30 ST2's, and I'd say a stage 2 ed30 will pull away until a higher speed, not just stay with it. Do you have something to back this up. Now a mapped 335d is a different matter........relentless
