Last night going home I had a little blast against an M3 (E36), we were both rolling at about 30 when we hit the dual carriageway, at first I pulled away slighty, but then he was up my chuff. I moved across to the left and let him past but he couldn't pull a head. In the end we both backed down as we were approaching traffic ahead.

Thing is I always expect the Scooby to be the fastest car on the planet and when you can't pull away or god forbid get passed I do get a bit anyone else feel this way?

My car is a 03 STi (UK) with TSL exhaust system and K&N panel filter although I am about to go for the EcuTek, De-cat Downpipe, & Uprated Fuel pump so that should help matters a bit if I come across the M3 again

 

BMW M3 (E36) '93-'98 6/3201 321/7400 258/3250 215 5.4 157

Subaru Impreza WRX STi £26,990 4/1994 300/6000 299/4000 207 5.2 148

Beemer 215bhp/ton, Sti (standard) 207 bhp/ton.

Subarus are NOT the only fast cars on the planet!! I know what you mean though, as most cars are of course a lot slower.

Cheers,

Ian.

 

your car did well if it was ppp'd or ecutek'd then the story would have been difference


however in my experience you need 80-100 bhp MORE to steam ahead of anything, depending on weight etc etc

What a coinsidense my car has an exhaust system and a panel filter aswell

I think you will find all cars have exhaust systems even the M3 it stops the engine bay catching fire

 

fastest car on the planet? what are you taking?

 

I have just realised that the figures I cut and pasted in my first post (from Evo), have the Sti down for 300bhp.

Stis are 265 are they not? Does that mean the bhp/ton figure is correct at 207? Hmm. So with 300bhp it still falls short of an M3.

Ecutek on top of an Sti with de-cat - does that give more than 300 or about 300?

Makes my MY95 WRX with about 210-215 bhp/ton good value at £5k

 

sti bugeye non ppp is 217bhp/ton
sti bugeye ppp is 247/ton

iirc

tek 3 with decat etc etc should give about 340 ish bhp

however if you get a DAMM good mapper a ppp'd car can get about 320-330 bhp just with a remap...

 

Very confused - figures don't add up at all.

We are talking metric tonne yes - 1000kgs.

Classic is 1235kgs. Hence a P1 with 276bhp works out at 223 bhp/ton by me (Evo quote 219 so about right).

Bug-eye is 1470kgs. Hence a WRX Sti PPP with 300bhp works out at 204bhp/ton by me (Evo quote 207).

So where do you get 217 and 247 from - what figures are you using?

 

The Spec C (according to Evo again) has 247bhp/ton, which equates to it weighing 1350kgs. Which makes sense as it would be lighter of course.

 

ahhh i may have my figures wrong the 247 must be from the spec c ooops sorry

hawk

 

Meant to say TSL exhaust system and K&N Panel Filter

 

P1 is 1295kg

Of course most cars need fuel and driver addings, so bhp/ton calcs are more often than not wrong.

Paul

 

No probs. Ok ignoring Fuel and driver weights etc.

So, new Stis:

standard Sti(265bhp)...........- 180 bhp/ton
Sti PPP (300bhp).................- 204 bhp/ton
Sti PPP re-mapped (330bhp)..- 224 bhp/ton
Spec C (335bhp).................- 247 bhp/ton

from original post:

M3 (E36 from original post!)...- 215 bhp/ton

and (using 1300kgs to include air con etc.):

My Classic (280bhp).............- 215 bhp/ton



Glad we cleared that up

 

Thanks StiX, I only think I would be running about 275bhp with the mods I have on so far so only about 187 bhp/ton. So I guess I should have expected the M3 to beat me. I am sure if I had pulled over sooner he would have got passed, oh well you have to give it a go. Roll on EcuTek

 

eeeek didnt realise std sti's were sooooo low

 

God yes, thats why we buy cars like this - it ain't for fuel economy

IMO the bhp/ton figures are pretty good for comparisons. The other day I came across an Aston DB7. I passed him on a slip-road to M4. He didn't like that so blatted past me after I had settled at 80. So I thought.....what the hell!

Lots of traffic, but I followed him all the way into Swansea centre (about 20 miles). Could he get away......nope! I was right behind him upto a ton on a couple of times we could. Sounded the biz though.

Got back, checked the net. V12, 435bhp - eek! But 240bhp/ton, so not much different to mine.

 

Nor me until I worked the figures out this morning!

Very happy with my old scoob at the mo. So happy I'll almost certainly get another. So I was thinking maybe new age Sti or WRX modded to about 300 - bound to be quicker.

But no - looks like I'll need one with 330bhp+ to be quicker. May as well wait a while then, I'll just mod mine to 330 instead - which would give me 253bhp/ton

I'll stop working figures out now - sorry! You can tell I'm bored.

 

The really important figure is how much bhp/ton is making it to the tarmac!

 

Your right there, which gives the M3 from the original post more of an advantage again - more power needed!

 

<Star Trek Mode On>I need more power captain<Star Trek Mode Off>

 

The straight six displaces 3,246cc and develops 343bhp (only 333bhp for our American cousins, sorry guys) at 7,900rpm. Much work has gone into allowing the engine to rev higher (to 8,000rpm) which in itself boosts power by almost 7% compared to the old engine. Despite now being a higher revving, this is no peaky engine. 80% of the maximum torque of 269 lb-ft is available at a piddling 2,000rpm.

What does all this add up to? It means it can propel the 1570kg car to 62mph in 5.2 seconds and on to an electronically limited (why?!) 155mph.


What raises a smile though is the price of each new.

BMW - £39725

STI - £23995

Diffrence - £15730

Now if you spent the diffrence on mods, you would be talking 450 - 500 bhp surely.
