110mph isn't bad for a 1.4!

1. Have you had the car mapped to take advanage of the mods?
2. Are you very fat? (no offence but lots of weight would massively reduce performance)

 

I would say that is fairly reasonab;e my 1.6 25 vhas had it at about 115-20 ish (not that i drive that fast of course:lol: ) but Ive only got the 52mm throttle body and induction kit with cold air.

Have you had the FSE set-up on a rolling road after all the other mods were done?


PS. What year is your car?

 

Considering most 1.3 cars don't do 100mph, it's not bad at all...

A Ford Fiesta 1.3 does 96 Flat out, and 0-60 in 14.8sec.... it aint doing bad...

Book says 105 for the 84bhp, 112 for the 103 BHP.

110 Seems "underpowered".

Turn off Aircon, shut windows, don't have a full fuel tank... and see the difference.

Also, wind direction can make 5-10 mph difference....

 

Cosb, what can ur TD go up to?

I've never got my SD past 115

 

Is it the 84PS 1.4 engine?

 

hmmm that is sluggish....

Mine will beat or at least keep up with most 1.6's and i havnt got the fancy performance stuff like urs!

my clock read 120 top speed and with my 17's i gotta add on 5.95%..... (but then i suppose take the same off for speedo innacuracy!)

Also..you are aware that you will go faster in 4th gear than 5th? (i hope u are!!)

and if it is the 84ps 1.4 then u def need to get the 52mm TB...you should see speeds of 125 with all the other stuff uve got.

 

Also..you are aware that you will go faster in 4th gear than 5th? (i hope u are!!)

Will you? I've heard this before, but I find that hard to believe. I just got back from holiday in Austria. So I could finally see how fast my car is on the autobahn in Germany and it did a little over 225 km/h (145 mph) on the speedo. I don't think it would have gone any faster in 4th gear .

 

lol well official figures say so...ill dig them up in a bit

 

Phil is right about the 4th gear, 4th is a shorter gear so will get to the top speed quicker, of course in theory you should be able to get a higher speed in 5th coz the revs are lower but the power isn't there as standard

 

here ya go...and thanx jon

 

Mmm, I'll probably have to wait till next holiday to test it . But I think I would have hit the fuel limiter in 4th gear at 145 mph .

 

Interesting. Do you have such a diagram for the VVC as well?

 

they dont do the 25 1.8 nemore so i dont know where to look for the figures..

 

Or a diagram of the MG ZR 160 maybe? (I do have a 160 bhp MG F Trophy engine in my car, so I think the topspeed of my car won't be much different from the ZR 160)

 

only reason you can get a higher speed in 4th in a 1.4 is because there isn't enough power for 5th

engine will be doing less revs at 105mph in 5th than in 4th, so providing you had the mods to increase power you can go further up the revs

when my R25 was standard I could do just over 115, after mods and a big increase in power I could do 130mph (I was at 4700rpm and in the red though )

 

Yeah it looks like anything above the 1.6 will go faster in 5th... so your 1.8 will prob go faster in 5th...

Thing is..this guy is running a 1.4 so his shud go faster in 4th...

 

Yes i also have the 52mm throttlebody on

 

ZR160 speeds in gear...

 

compared to the standard PG1 box in the ZR120.

Note, it won't of course achieve this speed, but this is what the theorectical maximums were, should you actually be able to red line it in 5th.

 

If only the ZR had a lower cD eh Steve

 

So would it b possible to put a 160 gear box in to a 105 and would it go straight on

 

That theoratical gearspeeds of the ZR160 are pretty much what's possible in real life.
When the road was going a little downhill (on the Autobahn, so perfectly legal) the car was doing 150 (on the speedo) and still going. I had to slow down for someone who was overtaking, but I'm sure I would have hit the end of the speedo at 7k rpm.

BTW Why is the theoratical topspeed of the ZR120 higher than that of the ZR160?

 

Suzuki swift

My Suzuki swift did 127 with 2000 rpm left to redline. My little monster is a 1.3 dohc Gti. It still did 0-60 in 6.9 seconds. I dont know the quarter mile time yet but hopefully at trax.

The reason i'm saying this is because engine size doesnt really matter for speed. My swift is chipped with full s/steel exhaust and rally cams. Not to mention the monster s/steel filter.

Its probably letting out 160bhp, considering it is 110bhp standard.

I advise any real racer to buy a swift gti for the weekends.......

Different ratio final drive.
