acceleration

[Beech36]

right got a pretty much standard saxo vtr i want acceleration brilliant but i don't want top speed killing. What options have i got?

Diffed series 1 rallye box! :-)

But seriously it depends how much and what you're looking to gain as people could be here all night throwing suggestions at you.

[Beech36]

diffed series one rallye box? Would 1.1 saxo box be just as good? Name some main things. I want her to be a monster hhaha

[monka]

gti or vts box with a vtr/diesel 5th gear

Name a budget and I don't think anything will compare to that, unless you pick your own gear ratios and own final drive etc! :-)

[Beech36]

doesn't vts kill top speed on vtr tho?

[Beech36]

errrrrm i wud spend roughly 500 total on acceleration maybe more depending on how much it wud help. Accept from turbo

I'm unsure what to suggest apart from a manifold, good induction kit and a nice flowing exhaust, strip it out and there's a start :-)

[Beech36]

got most of that coming. What about gearbox wise? So many people tell me different things. I want a gearbox to increase acceleration bt that won't drain top speed

[Prickle]

Dear god..

id 16v it for that instead.

[Beech36]

haha insurance wud be issue then lol. What gearbox is better? Vts or 1.1?

[crutchs]

Strip out what you don't need that can be a very cheap way to do it? Hah decent intake and exhaust

[Chr15]

fail thread is fail

S1 rallye box will help a lot acceleration wise and are widely wanted hence the price tag they generally carry, and in all fairness I shouldn't imagine you'd notice the final drive?
Unless you often drive at 130+ mph.

105 mph max from a VTR with 6250 rpm rev limit when an s1 rallye box fitted. Makes it a hoot to drive though

Agh I forgot 8v! :-(
Thanks for correcting XD

turbo charge the engine. that or get a vts.

[Beech36]

how much does turbo charging cost i may just start savin

[Danny78VTR]

Your looking about £4k in new parts or can do it budget for about £2k down the 5th injector route
im having my car booked in for a turbo build ;), not as simple as a turbo on exhaust job done, read into it and then you get the understanding of it all :)

[W343NNA]

LMFAO, Vts it, "insurance would be a issue then" Might turbocharge it Oh and insurance wouldnt be a greater issue then...

[titchster]

You don't want to lose top speed, but want better acceleration? Considering a VTR will do what? 120mph flat out? A VTS box is still to do 122mph on with a 6200 rev limit. And a 1.1 box is geared for 125mph...


Why don't you want to sacrifice top speed though? Doing those kinds of speeds on a road is just downright stupid TBH, and it's extremely unlikely you'll get to them on a track in a relatively standard VTR.


I put a 1.1 box on my old 8v, never topped it out, and it accelerated quicker than any other 8v I came across. (Except for a mate's S2 engine'd S1 Rallye with an S1 box, that fucker went like stink).

Other option, is to strip the car, less weight = more go.

[SnakeVTR]

Another point you dont want to over look is that a 1.1 gearbox on a vtr is under extra load i.e more torque and horsepower than the gearbox was rated for, and if your gonna be thrashing the gonads of it because you like the acceleration it probably wont last very long. I have seen this happen many times, people think the gearboxes are the same exept for ratios but they are not, the sun/planet gears and bearings are not as strong as vtr/vts gearboxes :y:, a Rallye box on the otherhand should be able to cope as they are from a car with similar power as the vtr :y:

[titchster]

it probably wont last very long

My 1.1 box lasted for over a year on a VTR engine, and over a year on a 16v, and that was used on track and 1/4 miles, lots. Was still fine at the end of that too, AFAIK, the only reason it didn't go longer was because I took the car off the road and broke it for spares, otherwise, i've no doubt it'd still be going now.


With mechanical sympathy, they're not as weak as people make out.

[NismoSteve]

Yes acceleration is nice to have, I think even the vts box is really low geared, I have a 50mile commute to work, mostly motorways and to sit at (a true) 75mph its revving at just over 4200rpm.
My old pug 406 2.0 8 valve turbo would be sitting just under 3K at a true 80mph.
I'll have to see what its like with the BE box when I get round to that.
