B14.4e Parts/engine.

I meant the diff ratio is good for 165mph...not that it would do it from the factory Ryan's 740 would do 150+ with ~230bhp, and with the current 275-odd, it goes off the top of the 140mph scale rather quickly! A 360 with 250-300 should be fine to do those kind of speeds...on power grounds, at least!

I had the pleasure of taking my car to Elvington a couple of years back. I have a nice (blurry) picture of the needle a fair way off the top of the scale.

Huskyracer's 340 1.7 Turbo will do ~150 when it hits the 7500rpm limiter with a 3.64 (1.7) diff. He said it was "interesting". I've now given him a 3.36:1 diff, as apparantly 150 isn't fast enough

hence me keeping my 4 speed box.. and 3.61.1 jobby diff:D


*cough*trying to get hold of an eton...*cough*

[foggyjames]

The 5 speed is better in every other way I can think of...but the ratios *may* work out that the 4 speed has a higher top speed than the 5 speed. A 5 speed will get there quicker!

Hmm no idea why you'd wana keep a 4 speed box, it makes the 1.4 painfully slow whilst in 5speed guise its not bad

[Jason B]

isn't the 4 speed box just the 5 speed ratios without 4th gear.

[Chris_C]

It's without 5th gear, and the diff is longer to give roughly the same speed, but with less accel.

Been thinking about this, I remember guess-culating you could get 170 out with the 3.36, and wondering how much power you'd need to do that given the 'aerodynamics'
Great to hear husky can hit 150 with (is it?) 210hp, that should mean 170 is within the realms of reality.
Still, my 60 was terrifying when I eventually got it off the clock, and I'd be really worried about lift at those speeds!

[foggyjames]

I don't have the data to hand, but I'm pretty sure the ratios are a little different between an M45 and M47. Only a little, mind...

cheers

[kaos]

i had the data availble to me..

but i dont untill i go pick up some more b172 parts..

still which one of you that has posted a million times want my lovely B14.4E

[classicswede]

I've had an indicated 120 MPH from a 1.4 I think 4 speed. But in real terms that is only about 105 - 110. I dare say on a long down hill you could possible get a little more

[filthyjohn]

I think the speedo's pretty accurate. 99 indicated on mine is 100 on the tomtom

[Chris_C]

The speedo's vary loads, Fake is about 10% over according to my GPS, Andy's red car is only around 3% out to the same GPS.

[foggyjames]

I'd say it's more likely to be related to tyre size than the speedos themselves...although they won't be perfectly consistant.

i am running sexy 13"s

[foggyjames]

...but what size tyres

cheers
