Over 100mph

[conor]

On my private test course of course my vtr is quite nippy up through the gears but when it comes to around 100mph its :n::n::n: she can go off the clock at 120mph but takes around 3hours lol So I have a backbox and an air filter. I know people will say a 4 branch and a proper race system but again, what else can i do?

[frankie]

backbox wont do shit,

get a decat, get an enclosed filter (if you havent already)

strip it out

[conor]

Cant see a big airfilter doing much, only on a turbo yes. Need the car for general use so cant strip it and already got a de- cat

[frankie]

enclosed like a bmc, not the open gay ones.

cams?

change vtr box for a vts (no hp gain)

[VTR-Chris-VTR]

Why would you wanna go over 100mph anyway? unless u use it for drags :p

Only way your gonna get it to have power after 100mph is maybe some cams&remap this will help abit, but you will need as much BHP as possible cos of wind resistance and drag etc

[conor]

Is a remap anygood without cams? Might drop a vts lump in it

[VTR-Chris-VTR]

Is a remap anygood without cams? Might drop a vts lump in it

Most people will say its pointless re-maping your car without any majour engine mods.......so no point as you wont gain the full benifit of the re-map

VTS lump will be good, cammed up with trottle bodies then you will be speaking power :y: but will be expensive

[Ste]

VTS lump would be perfect for what you want at a sensible price. A few people will probably dispute this but a VTR just hasn't got the torque to give it any go out of 3rd.

With the VTS conv you get a higher limiter, shorter final drive and 30bhp. - Strip it and the usual breathing mods and jobs a good un.

[frankie]

vts lump :Y:

[gd16]

With the VTS conv you get a higher limiter, shorter final drive and 30bhp.
Assuming you get the VTS gearbox as well, just in case theirs any confusion.

But as said - the cheapest/easiest way to get more power from the Saxo is to put in the 16v engine. Could probably be done for £500 if you manage to source one that'll match up (well... get very close) to your wiring at a decent price and do the work yourself.

[jonezy]

VTS gearbox would help acceleration on the VTR engine no end also as VTS conversions can be expensive

[carlos45]

i had a vts box on my vtr, went through the gears quicker, but still no where near like the vts engine tbh.

[jonezy]

just a thought as the g/box is £150 max,

my VTS conversion so far has cost me about £1150 so far.

and thats doing the work myself, the engine isnt even in the car yet.

[Toad]

This is the sort of speeds where smaller engines show their characteristics; generally not giving much acelleration.

If you want more acelleration above 100mph, you will need a lot more BHP. Weight reduction will only help so much, it's all about the ponies I'm afraid.

[AlexB]

cam the hell out of it mate
or as said
vts convetion
im afraid without money being spent your not gonna get the results your after

[rushy_23]

Like Toad said.

Bigger car tbh.

[djmartin]

cam it
vts converstion
turbo/supercharger or throttle bodies
gmc/janspeed/supersprint or raceland manifold
sports clutch
lighter fly wheel
uprated crankshaft
bigger piped exhaust system
bmc or evo sports induction kit
bord out inlet manifold
better spark plugs
better oil
uprated brakes (bigger calipers etc etc)
roll cage
rip out the cars interior just have drivers seat nothing else

cant think of much else tbh lols

[Quick]

Reduce drag on the car!

Smaller mirrors, a good polish!!!

[rorz_vts]

when did you last have a service done on it mate my vts was ruunin dead slow top end 120 about 2 weeks back had a full service with high performance oil and triple plati/diamond plugs a cam belt change put on a full exhaust kit and an enclosed induction kit an its goin of the clock at 140 now an is pullin like a mother all good

[Matty-VTR]

Mine reads 110 in 4th, but 5th is way to long for the little power available. You need a lot more tourqe to pull the gear

[KamRacing]

you'll rarely get that fast on track so i'd consentrate on getting to around 100 quickly and tuning the suspension / handling so that you minimise the loss of momentum on the bends.

G

[duggy]

Why you need to go over 100mph in a daily runaround? lol :panic:

[Bounty69]

i got 135 out of my vtr on the motorway...very slightly downhill with a full car. quite sluggish getting thru the gears tho.

[tommyVTR]

hmm 135... what mods u got?

[Barry123]

hmm 135... what mods u got?

an incorrect speedo...

[Toad]

G

Indeed mate. Unfortunately I don't think a lot of people here think like that however. It's more like: Did a emfree at 140 innit...

[Raz]

tbh....i prefer 0-62 times than top end speed...never going to need top end speed really....especially on track....

i would concentrate more on the handling side of things so you can take your 'speed' through corners...

the VTR engine will do me for a daily driver :)

[Predator_R32]

i do hope this 100mph was on the track

[VTR-LEE]

Why you so bothered bout been the fastest top end boy around its not gonna happen with a 1.6 is come on lets be serious you can do it and it will be seriously exspensive and for the cash you gould by any second hand over 200 bhp car ie celica GT4, RX7, ect ect which will go past the 100 no probs,

But when are you gonna do that any way on the roads with out losin your licence or crashing coz you could not stop in time ?

[VTR-Chris-VTR]

i got 135 out of my vtr on the motorway...very slightly downhill with a full car. quite sluggish getting thru the gears tho.

Bit silly going that fast on a motorway really, but ur speedo was mostly likely out by 10mph mate........i mean now i reckon my VTR wll only do about 115mph, and its even got stainless system and sports cat on it

[VTR-LEE]

He can do what ever, its the full car thing that is stupid at that speed

[Barry123]

Question:

How is a VTS box going to help achieve a higher topspeed?

[nazz1]

Question:

go through the gears quicker, more momentum to keep you going

just a educated guess, probably wrong lol

[Barry123]

just a educated guess, probably wrong lol

yep dude you are I'm afraid. lol, sorry man it was a rhetorical question from me :D
you'll accelerate in gear quicker but when your up past 60-70mph the aerodynamics and outright power are much more relevant to attaining the higher speeds.

:)

my mate said he got 137 in his vtr.. NO MODS AT ALL! slip streaming his mates vts.. still dont belive him.. :)

at the end of the day your smarter than me

for a start you got a diesel that does like 5000 miles to a tank

[nazz1]

my mate said he got 137 in his vtr.. NO MODS AT ALL! slip streaming his mates vts.. still dont belive him.. :)


his mates vts is infact a vtr with vts badges, and vts wheels

hes been caught out

[Roy-VTS]

im sure the gearbox wont let you hit 140 in a vts, when i tracked mine it hit the limiter in fifth at about 130 ish maybe less

[Mr_X]

i love all this bullshit about it being on a fucking track, or on "my private road". total wankers

[Barry123]

at the end of the day your smarter than me

I wish! I'm no smarter than anyone else dude... you're probably a billion times more practical than me and know how to change this and that on a car - whereas I'm dumb enough to pay other people to do it as I don't have a clue :n:

5000 miles to a tank :D if only ha!

[Roy-VTS]

alot of the more serious members on this site have and regularly 'track' there cars

[MiniGibbo]

buy a car designed to have power over 100, a saxo no matter what has been done to it eg boosted or spray will still suck over 100

for example a 250hp ep82 will 0-60 in around 5.5 secs with traction but will still lose 70-120 with a stock mondeo disiel on a dualy lol :homme:

[conor]

Cant as im only 18 and cant get insurance on anything much bigger

[rorz_vts]

im sure the gearbox wont let you hit 140 in a vts, when i tracked mine it hit the limiter in fifth at about 130 ish maybe less

just sayin what me speedo said laa an that was at about 7000

[Roy-VTS]

just sayin what me speedo said laa an that was at about 7000

fair enuff m8, surely some speedo's have descrepencies (spelling) and maybe some vts's go fasters than overs the only way we can all back it up is official results using official equiptment

[kirby351]

just a thought as the g/box is £150 max,

my VTS conversion so far has cost me about £1150 so far.

and thats doing the work myself, the engine isnt even in the car yet.

why didnt you just buy a vts to start with surley cheeper ?

[scottyvtr]

Need the car for general use so cant strip it

. - Strip it .

rip out the cars interior just have drivers seat nothing else


???????????? :p did i miss something lol ????????

as said do the conversion change the gear box etc etc if you have the funds !!!!!!

[Joesnow]

yep dude you are I'm afraid. lol, sorry man it was a rhetorical question from me :D

:)

A question for you...

VTR
Max power - 98bhp @ 5700rpm
Max speed -116mph @ 5115rpm

It reaches its max speed before max power is reached, not using all of the engines power. If the gear ratios were changed so that it would do 117mph in 5th at 5700rpm, would it pull to 117mph? If so then it would have better acceleration and a faster top speed…

Getting back to the original question, a gearbox change is the best thing you can do £/performance in IMO… much better than filters exhausts etc. 5th gear on a VTR is far too long, a change to a VTS box will see you get to an indicated 120mph in much quicker than 3 hours!

[KamRacing]

the max speed is limited by the engines ability to push the car through the air ie power. The gearbox is physically capable of going faster for sure

[VTR-Chris-VTR]

If you had alot more power from your engine, then the 5th gear on a VTR box will be fine........its not the box its the engines power thats slowing you down after 100mph, like Kam-Racing said you need more power cause of the wind resistance, even spoilers slow you down abit due to the drag, but yes a VTS box will help abit but not alot that you will notice i dont reckon

[andywiddss1]

vts engine an s1 106 rallye box geared for 120mph end of story mate

[saxokid100]

You get vts motor in your motor for more power matey!!!

[andywiddss1]

im running 157.4 bhp an s1 106 rallye gearbox catch me if u can too 120mph ha ha

[vtr130]

Ive done 138mph on gps!! :)













Before u get all bitchy it was at brunters ;)

[vtr130]

And the speedo was round on the mileage part between 0 and 140, lol

[Ryan]

and the knob in the drivers seat was doing his hair :P

whens the feature out from that dude any idea??

[andywiddss1]

ha ha not on a s1 106 rallye box mate , when i had my vts box in would pull 145mph easy

[vtr130]

Next issue mate :)

Going to be good hopefully....

[vtr130]

ha ha not on a s1 106 rallye box mate , when i had my vts box in would pull 145mph easy

On gps i do doubt it!?

Unless u have a stupid limiter over 8k

[Ryan]

let me know when that issue is out please craig. and if you get it IF any of my pics ahave been used.

[vtr130]

Ok dude

[andywiddss1]

not bitchy vtr130 we all play the game

[andywiddss1]

speedo reading mate not gps so like u say 135ish

[jpsaxo]

vts box with 7,800 limiter is 145 iirc

[AlexR]

You can actually increase top speeds with different gearboxes.

Few examples:

Takes 110bhp to make a saxo do 127mph(real not speedo) if your car is at the wrong point in the rev range(say a vtr box on a vts) doing 5500rpm at 127(theoretical) then it can't reach 127 because it's not making enough power at that rpm, however if you fitted a shorter gearbox it would be revving higher and making more power so would be able to go faster.

fabia vrs, makes max power at 4000rpm, power tails off very quick with the standard turbo, say a remapped one would be capable of 10-15mph more than a standard one but it's geared for a standard engine so it's not making much more power at 4300rpm than a standard engine, and a higher top speed would require it to rev higher than that, so the potential is there for more top speed but the gearbox is limiting it.

Both instances are expecting the gearbox to be geared for the max power to arrive at the max potential speed of the car, however this will compromise the gearing for every day use and possibly reduce the straight line acceleration. You can be revving too high or low to get the top speed.

[jonezy]

why didnt you just buy a vts to start with surley cheeper ?

VTS's were expensive at the time i bought mine.

mine was also the only unmolested car i could find in my price range

insurance is cheaper with flux due to extensive mods, shows me to be an enthuisiast.

also i didnt anticipate it to cost this much, the cylinder head alone cost £550.

everything is being replaced so will be uber reliable

[Toad]

Yep, I agree completely. If, for exmaple, the VTR could hit 116mph @ 5600rpm, then there's going to be potential for top speed to increase.

In working practice, I can give you a good example. Running an S1 box, the car will not acellerate that quickly from 120 - 130mph, due to the fact that the RPM gets so high at 120mph, the engine drops out of its power band. However, with my stock gearbox, I could get from 120 - 130 considerably quicker as I was in my power band.

The VTR example is very similar, as it's all about where the power band is...

Just read this, and I agree too. :)

[vtr130]

I swear i was doing 8000rpm in 5th josh at brunters when they said it was 138mph!! Was scary there though with the crosswinds and stuff the car was swopping across lanes. lol

[Toad]

On paper, with 195/45/15 tyres, I think 7800 should see around 145mph, maybe more...

[Sean]

On paper, with 195/45/15 tyres, I think 7800 should see around 145mph, maybe more...

vts with vts 'box will hit 151.8mph in 5th@7800rpm ;)

[jpsaxo]

On paper, with 195/45/15 tyres, I think 7800 should see around 145mph, maybe more...

Thats worked out from gearbox and tyre size, so in theory should be right but who knows

[vtr130]

Well i thats what my speedo said not gps ;)

Anyways go buy the new redline mag all of you little F****s lol

[Toad]

vts with vts 'box will hit 151.8mph in 5th@7800rpm ;)

Nice one.

This is what makes me wonder about the accuracy of these GPS devices. They show a much slower figure than what you should be at any specific RPM.

or just get smaller tyres....

[Toad]

or just get smaller tyres....

Smart arse! ;)

[Sammy]

Lots of nos! But in all seriousness cheaper to drop a vts in it. I would rather build the 8v lump. Cam, headwork, manifold, decat and catback, bike bodies then get it mapped. 130 to 140 bhp and a mental noise when you wind it up. Bit pricey though
