is my vts on drugs?

[lavo-vts]

only had it a month. it has piper cams, big valve head + ported n polished, straight through exhaust and a vtr gear box its top speed is 145mph! is it just me or is that seriously fast for a vts?

[saxodan]

I think (dont quote me) that the top speed is 130 for a vts?

So an extra 15 mph is feasable

[SaxOmniaC]

yes it is on drugs, it got them off me!! ;)

[SaxOmniaC]

called speed!:P

not far off it dan

[saxodan]

Ok, here is your car spec- http://www.parkers.co.uk/choosing/specs/data.aspx?model_id=127&id=13058

The top speed is 127 mph, im not sure how much more bhp the mods you have done will give you but not i lot i presume.

And bare in mind that the speedo is out by a lot once you go over 70ish

Its probably reading 145 but your getting no more than 130ish

[lavo-vts]

sweet, was told by the guy i bought it of that its 157bhp does that sound bout right?

[rushy_23]

Dan is most likely correct, speedos are only an estimate, take it over 100 and it becomes more and more out.
Must still be pretty rapid with those mods tho.

[saxodan]

sweet, was told by the guy i bought it of that its 157bhp does that sound bout right?


Think hes pulling a fast one... the car came with 120 bhp when it was made (no doubt its lost a few horses over the years)

I very much doubt it is 157.. but i may be wrong

[ets2k9]

It does seem optimistic and the VTR box is a bad choice for those kind of mods.

[lavo-vts]

thats what i was thinkin. but i goes like the stink anyway

[lavo-vts]

whatr the difference betweeen the vtr n vts boxes??

[saxodan]

I thought the vts gear box was similar to the 1.1s?
(meaning the ratios are shorter)

[Saxoladlesta]

Yeh your VTS gearbox has a better ratio then the VTR one so I have no idea why you would want a VTR gearbox in your VTS

[ets2k9]

I thought the vts gear box was similar to the 1.1s?
(meaning the ratios are shorter)

Your correct the 1.1s are very similar and have shorter ratios for accelaration.

SSC Ratio thread (http://www.saxosportsclub.com/forum/posts.asp?threadid=270887&forumid=5)

[boz]

the vtr has a slightly longer last ratio than the vts i think, the vts has defo got closer ratios than the vtr.

[Barry123]

1.1 and VTS are the same ratios barring the final drive ratio

and 145 indicated will be around 130 actual.

[saxodan]

145 indicated will be around 130 actual.


Woo thats what i said i feel special .. ads is allways right aswell :geek: hes a rocket scientist or something..

the word you are looking for is god :cool:

[beastgtir]

the word you are looking for is uni student :cool:

i think ad is the most knowledgable person on these matters as he has the next thing down from a VTS. :hijack:

i think even a modified VTS would struggle to do 140+ and would be all over the road!

[slammed_vtr]

maybe hes put a vtr box in for a better top end ... i say this because if you put a vts box in a vtr u gain acceleration but lose top end so i think in my humble opinion if u put a vtr box in a vts u will gain top end and lose acceleratoin ?

so it may be almost right but they speedo will be out aswell

right or wrong?

[Jaz]

I've had ma vts at 137( probably only doin 125 ) when it was standard, the speedo's goes well off once u get by a ton

[RIBstaff]

Ive also seen 140 when my vts was standard

http://video.google.com/videoplay?docid=8463732027944869587&q=vts

[lavo-vts]

i can assure u all that 145mph is possible in a vts. i should know ive done it and have seen it done by others

[willsy]

Best way to test your speed is to borrow a sat nav or something, the speed from that will be very accurate. Obviously dont do it on a public road else itll be a police camera or speed gun thats giving the accurate readings

[Scott]

hurrah for inaccurate speedos, when it first shows "140" on the clocks its doing about 6400 rpm = 124mph. Foreign car to.

[lavo-vts]

sat navs arnt spot on. best thing is to try it near a speed camera

[RIBstaff]

How much does yor vts rev to? Myself around 7,7000

[Barry123]

Yeah you just need a turbo.

sat navs arnt spot on. best thing is to try it near a speed camera
More accurate than a speedo

[spencer_cammedvts]

mine pisses 130 on the clock and thats with about another 1500rpm to go till i hit the limiter and you can tell if you have more road it will go 140 (on the clock that is)

[spencer_cammedvts]

also depends what wheel circumference you got as to how accurate you speedo is reading and its been found that 16's with 45 profile are the most accurate. still a bit out though

[lavo-vts]

my vts revs out at 7600rpm when the life savin rev limiter kicks in

[lavo-vts]

Yeah you just need a turbo.

stop quotin me!

[Japman]

ive had my vtr jsut ova 135 on the flat.i couldbeleave it.they give it 117mph...mine does that in 4th

[CampDavid]

I have clocked 142mph in my camm'd VTS with PT51s and a remap. The speedo read a whole load more but thats the GPS reading. The car is very well setup suspension wise so it felt stable enough.

[bullit]

camp what is your sus setup, ive heard its good

where did you get your btb zaust? gmc?

[CampDavid]

Mine came of Stewart Toals car. He was selling his so I bought the suspension, brakes, wheels and exhaust off him

[bullit]

cheers. ill be asking you some questions on suspension soon then, lol.so many options to choose from. doing the engine at the minute then will be hitting suspension

[CampDavid]

I'd do it the otherway round ;) suspension makes the car much more fun than lairy engine work. Brakes are fab too

[bullit]

i knew you were gonna say that, lol. run konis at the mo which are ok.

i also would do it that way but in need of a map at the min, but im gonna go standolone and tbs, hopefully soon, but buying a 42inch plasma last week hasnt helped. then it 4 pots and then sus.

[CampDavid]

Nice, though I'd only go for bods with lairy cams and good headwork, don't seem to get much more on something like 708s or PT51s (Bunney managed 2 bhp more than me with bods on the same rollers)

[Simo]

VTS gearbox will take you to 141mph (by calculation) if you can get the revs to go right around to the limiter. A standard VTS wont manage this unless you find a big hill :P

Swapping to a VTR gearbox will reduce acceleration but will significantly increase top speed on a tuned VTS (ie, you need to be able to reach max revs again) a VTR box will see a tuned VTS upto almost 160mph... but I dont think i'd like to be sat in it at the time!

I've taken my car to 138mph at Bruntingthorpe (measured by sat nav). It felt fine but I didnt push it any higher. I dont have a rev limiter in my car so self control is the order of the day :P

[CampDavid]

Increased the limiter to 7850 Simo, was reading about 7300 IIRC

I'd imagine at 138 you need self-control to keep your underwear clean!!

[Simo]

I used to have a 7700rpm limiter. Now I dont have a limiter at all. (Blank ECU)

Well check you ;)

I would love to build a TU engine to rev higher, apparently the bottom end will go to 10k. Its the top end that needs the work

[Simo]

I remember back in the day, Dave Sharpe had his revving to about 9000rpm IIRC, but the head didnt last long.

He had a lovely stack dash revmeter for a while though :A:

[CampDavid]

Mine will have done its 50 thousanth camm'd mile soon so the head may come off at some stage next year for a total rebuild by some of our F1 boys. Will possibly go lairy then. Depends on so many things though, right now I have a reliable 160bhp and its done 25k in 12 months, need another car to take the commute

[bullit]

headworks already been done. future,future plans will be to run some lairy cams and solids. if this wasnt my second car i can say i prob wouldnt be doing it.
