Right folks your help and knowledge is needed


My car ATM is 191bhp and 160ib/ft, with the LSD fitted it does 0-60 in 6.5 secs

I'm getting a turbo and other bits fitted in the next few weeks and it will push my car up to about 260bhp and 220ib/ft



My question is though what do you think my 0-60 would be?

Car weighs 1100kg on the weighbridge at work if thats any help?


thanks guys!!

High 5's if you can launch it and have traction i'd say.


edit: although, if you're talking Ford Fair - then i'd say 3.5 seconds

alan12112

Nice! - what does everyone else think?


I used this thing

http://www.letstorquebhp.com/calculator.asp

And it gave me this

Power at Flywheel (BHP) : 260
Weight without Driver (KG) : 1100
Power to Weight Ratio (BHP Per Ton) : 240.16
0 - 60 (Secs) : 5.04
0 - 100 (Secs) : 11.876
0 - 100 (Secs) : 6.83
Quarter Mile (Secs) : 13.38
Terminal Speed (MPH) : 106.18
Drag Strip Quarter Mile (Secs) : 13.18
Drag Strip Terminal Speed (MPH) : 108.12

Are these figures abit optimistic then?

good times you have there mate

alan12112

Cheers mate but are you on about the calculated ones?

I think they might be a bit optimistic!!

rossco22

I think the quarter mile time may be a tad optimistic (Quarter Mile (Secs) : 13.38) /// Drag Strip Quarter Mile (Secs) : 13.18

i've just used this and put my details in for my astra and it came up with a 1/4 mile time in the 11's, be nice if it did but i think its a bit vague as you can't enter gear ratio's or any other info for that matter. the best thing to do is have it timed when you've done your car

All depends on how much grip you have, how well you can launch, your diff etc etc

yeah i think they are a tad optomistic.

these are my results:

Power at Flywheel (BHP) : 330
Weight without Driver (KG) : 1250
Power to Weight Ratio (BHP Per Ton) : 268.24
0 - 60 (Secs) : 3.90
0 - 100 (Secs) : 10.19
60 - 100 (Secs) : 6.29
Quarter Mile (Secs) : 12.57
Terminal Speed (MPH) : 111.06
Drag Strip Quarter Mile (Secs) : 12.17
Drag Strip Terminal Speed (MPH) : 114.80

alan12112

Well I guess it is optimistic as I thought

So what do people think 0-60 wise then taking into accuont I get a good launch?

It's gonna be hard to practice as I pick my car up the day before fordfair and i'll be doing the 0-60 there!!

When does your car go off for the conversion Al? Is Arron going to FordFair?

How did you time the 6.5 in the first place?

I personally cant see it improving much from there just with more power, its traction you need, in fact it might get slower due to increased boost threshold on the new turbo making it harder to hook up.

Rab

I don't think it matters, 0-60 and so on, as long as it puts a smile on your face when you press the loud pedal

Which, I'm pretty sure it will. It'll certainly be a very capable track car!

alan12112

July the 19th mate - the saturday!! I can't wait!!

Scott's on about coming round to yours pal he wants to try my wheels on his car

I think Arron is coming but I don't see him that much anymore he's loved up with sara

alan12112

I have very good traction now chip even in the wet so thats not too much of an issue, I agree with what you are saying in principle but I do think it will help me get through the gears alot quicker, 60 is reached at the top of second in my car so even though the 0-30 in 1st wont be massively differrent i'm quite sure the 30-60 in second gear will improve vastly!!

It does that already mate but i'm just looking for that extra bit more!! I do love torque and the way turbo'd cars push you into the back of your seat and ATM I think my car is lacking a little on the torque front

Twellsie

iTrader: (1)

but your power delivery from the start line will be very differant from 190bhp N/A to 260 bhp turbo'd, there is a pretty good chance it will spin the wheels from the off and as soon as you start to develop more mid range tourqe they will keep spinning, change into second and again back on boost

I dont mind you and scott coming over al, we'll get a bbq going at the same time, just bring arron with you if you can as ill have my no-limit bumper for him to take, and i want my coilovers back

indeed, the problem with turbo motors coming off the line is a lack of torque at very low rpm then an excess of it in the midrange, FAR harder to launch with a FWD setup.

Definately!

With my 60ft times i just get under 4 on the 0-60mph...

think 13.1 is a bit ott imo

i would agree it's a TAD optimistic lol

rossco22

My results as follows,




Power at Flywheel (BHP) : 255Weight without Driver (KG) : 650Power to Weight Ratio (BHP Per Ton) : 398.610 - 60 (Secs) : 3.510 - 100 (Secs) : 8.8460 - 100 (Secs) : 5.33Quarter Mile (Secs) : 11.85Terminal Speed (MPH) : 115.79Drag Strip Quarter Mile (Secs) : 11.75Drag Strip Terminal Speed (MPH) : 117.18



if i could make these times i would be very happy... Not that i know for sure that i cant as ive never timed the car but i really cant see it to be honest..

pa_sjo

Those performance calculators tend to be designed for perfect hook-ups, eg rwd drag cars.. fwd is a completely different story (on a road car, at least). I'd be very surprised if a 270bhp mk6 Fiesta would break into the 13's, let alone anything faster!

GavStyli

with road legal slicks and a good driver 5 secs or under, ive done a 5.2 with 200bhp
but it also depends on how its setup and what the power delivery is like. mine is a smooth and progressive powder as thats how ahmed mapped it.

Twellsie

iTrader: (1)

i would be amazed if the time are anything like taht in reality, as i does not take into account, drag, gearing, tyres, wind, weather conditions, road surface etc

foreigneRS

depends what you are doing to turbo it as well. are you keeping high compression and using a large turbine and low boost to gain mostly at the top end, or lowering CR and having mid range boost?

As above, Id be amazed if it touches 13s tbh!

My XR2 had around 260bhp, weighed about 800kgs, and ran a 13.1 @ 111mph on a quaife diff and Toyo R888s.

You'd be doing very very very well to get 13s imo.

Fast Guy

That must be why it's almost bang on with my 4x4.

Power at Flywheel (BHP) : 280
Weight without Driver (KG) : 1130
Power to Weight Ratio (BHP Per Ton) : 251.77
0 - 60 (Secs) : 4.100 - 100 (Secs) : 11.076
0 - 100 (Secs) : 6.97
Quarter Mile (Secs) : 12.82
Terminal Speed (MPH) : 107.61
Drag Strip Quarter Mile (Secs) : 12.42
Drag Strip Terminal Speed (MPH) : 111.23

I've been timed to 60 in 3.7 (at York), and 12.43 1/4 at 108 (On Datron, 60 in 4.0, 100 in 10.0 1/4 in 12.5)


If it can get the grip (which will be the hard part) I think a 270bhp fiesta should easily break into the 13s and well onto low 13s if not 12s.
My old montego with slightly more weight (1160ish) and about 240ish bhp hit high 13s
