strip for a ton

[lee_capri]

i saw yellow escort pull 126 down the strip and a few others as well reaching well over ton are these cars set for just the strip? if so what advice could you give me apart from buying a escort to get more power already going to have it set up on rolling road would a chip be a good idea or not? would comp clutch make a differnce as i did'nt suffer from wheel spin on strip? taking the inside's out does this make a lot of diffence or not? what do you think

[Guest cortinamad-gonetoo]

what car you got now or is this question for a escort

 

id like to know too what they do

 

as far as i know theyre stripped out low ratio diffs decent boxes etc

 

lets watch this post and see what the experts tell us

[Burns]

what gear were you crossing the line in? if it's not top then fitting a different diff would make a difference

[Guest cortinamad-gonetoo]

cool do you mean 4th gear by top even if you have a five speed box

 

i just hit 4th gear before the line but could have possably gone over the line in 3rd

[Burns]

i was thinking of whatever is your top gear, 4th or 5th, LSD's make a big difference by all accounts (or welded diffs for the strip).

 

oh yeah, and makes a difference too

[lee_capri]

its capri 2.8lsd and going over the line in 3rd and its 5 speed box it was still pulling though as normel driveing i would change in-to 4th over a ton no wounder why it blows a leek

[Guest cortinamad-gonetoo]

woo mine was going over the line in 3rd but id change to 4th about 80

 

which is why i was differing between the two gears as my speed was 79 mph

 

burns is your sugestion to me to put a different ratio diff in mines 3.7 so would a 3.9 or 4.1 be better or is that the wrong way

[Burns]

yeah, in theory a 4.1 would give you better accelleration to your top speed, and since you're not actually hitting your top speed down the 1/4 then you'd get over that line quicker

 

what's the point of having a top speed of 120 if you're only hitting 80 over the line? better to have a top speed of 100 and hit that quicker over the line

[lee_capri]

91mph in 3rd what do you think boys

[Burns]

lol, smaller radius wheels and a different ratio diff me thinks

[Guest cortinamad-gonetoo]

lee capri

 

burns has helped me a little

 

im glad you put this post up

 

hope you dont think i tried to steel it

 

i think we should both go for a different diff

 

thanks burns

[Burns]

tis alright, tbh i've picked it up from others on here and learn theory quickly

 

that's what you learn from lurking on a car forum for ages

[brettp]

stick a load of gas in it gear it down

[lee_capri]

i have a 4.1 diff laying out side but would this be better than my lsd as my lsd did'nt wheel spin off line it just got on with it, would 4.1 diff cause wheel spin off of line also do the ones who pull top speed rev as lights are changeing or sit with throtal on a bit? as im not sure as this was my first time out :thumbsup:no worrie's dave good luck because i need it

[Burns]

couldn't you couple the 4.1 gubbins with the lsd and keep both?

 

i'm not really sure about the launching dude, i'm sure someone with more experience should be able to help

[lee_capri]

dont no but im sure some one will no on here to you burns p.s sweet pics of the day

[Burns]

cheers dude

 

maybe a question in the engines and transmission room may yeild more results

At the risk of attracting the wrath of the OSDC regulars I wouldn't consider a 4.1:1 final drive ratio on a 2.8i unless you're prepared to go to the inconvenience of swapping it back to the standard diff for normal road use

 

I'm assuming of course that this is your daily driver, or at least a regular road car? If so then for 99% of the time you'll not like it much with a 4.1:1 diff ratio. Losing your LSD would also be a step backwards, if you're determined to have the 4.1:1 then do not fit that diff, instead remove the CWP and replace your standard (3.09:1 I think) 2.8i CWP with it.

 

Plus to the best of my knowledge there's nothing in the 2.8i's fuel injection system to Chip, it's a Bosch K jetronic system isn't it?

[Burns]

that's a good point, i was talking purely about dragging your car, not road use

[lee_capri]

:lol:its not a 2.8 its a v8 rover running on tvr injevtion system pushing 190bhp when guy shut it down due to oil leek(blow)on left bank with moderfied prop and 5-speed rover box,2.8lsd and suspension no 2.8 ive had could take the abuse i give this has i kill 2.8s before i get them home dont matter what it is in neither misses wont let me have any-more 2.8s i tryed to buy a tickford on the sly but she found out so good buy tickford

In that case I'd definitely think carefully about a 4.1:1 CWP. Oh and by the way I wouldn't lose any sleep over losing to Deltamal, his Cortina is running a 241bhp NA cossie motor on Jenvey 45 TB's

[kevmk2]

My personal best top speed down the quarter is 131mph

Thats with a bog standard cosworth gearbox and 3.75 diff and 13" wheels

[lee_capri]

thanks for your help

To attain the speed over the line on a 1/4, first you must have the power, Torque produces accelleration and power produces speed, no matter what gears you run, if you dont produce the power you will not be able to produce the terminals, a 4.4 gearset will give you a better launch and accelleration , but will not give you the top speed you need if you run out of revs, where as a 3,5 ratio will give you the speed you need but you will loose out on accelleration and the car will be pulling its tits off trying to go faster against the gears, the terminal speed will be very similar in theory for both gears if your engine will carry the revs for the 4.4s

Terminal speed is allways a good indication of the power an engine is making, and of course weight will have a big factor

:thumbsup:v8ian queston would you no if they should be a rubber on the inside of dip-stic at the top , im going to lighten car up for next time out and see what happens
