Nil, Dave is correct on that one - 178.5mph at brunters and he only had 470bhp

 

where the power is made and how long it can hold it are far more important that the power alone.

You see so many graphs now that seem to concentrate on mid range torque to try and make them nice roads cars.

These do not cut the mustard on the top speed runs.

 

i think i do

i use the term ROAD CAR very loosely when talking about my car


what is the goal tho euan? whare will you stop?

i only ask as i watched kev spend daft money on his cosworths and i can honestly say i think he regrets it but when you get cought up in the topspeed crowd thats all you think about.

you get 185 but you want 188 next time,then you get that so you want to do 190+ and so on and so forth.

 

your right there Chip...

I know so many people that come up to me wanting to race my car and telling how they have 500 bhp etc etc

There has only ever been one car that has given me a good race.

the rest have been so far off th mark its untrue, yet all have 500 bhp

 

My next run will be it Dov...

I will not spend more cash on making the car more powerful.

It has pretty much the best of everything so I just want to enjoy it

I know what your saying about Kev and without ALOT of help from AVA I
would have propbably neede to spend alot more than I have.

 

great car tho euan,came from nowhare and tuned in scotland

 

Is that the wee Fiesta Euan

 

My car has a few different touches that others dont.

I genuinely believe that it can go a good bit quicker than it has before, I just need a bit more experience on the run way as people think driving in straight lines is easy....believe me its not as easy as you think

 

tatsxactly what i meant by my comment to dave! i know dave pulled 178 on 470 and was genuine.but it makes me laugh at the amount of supposed 500+ cars about that really dont put it out.

 

yeah dave the old devil sport fiesta was a quick wee thing.

it had me in acceleration that for sure maybe something to do with it running the shorter diff , 888's and a t38.

Bear in mind the nite i raced that I had a blowing manifold and I was on 400 ATW spec.

 

rods car makes all the others look slow

 

I suspect martin can prove that statement wrong.

I dont for a minute think he will beat Rod at top speed, Rod's car is far more focussed on that event, but I do think he will get close enough to make it look like less of a gap, currently the difference between rod and every other cossie at brunters is absolute fucking night and day, there just isnt anything else in the same ballpark!

 

Fastest cossie round the track....

Gareth Lloyd. End of!

 

Why has no one mentioned Ace performances 800bhp monster yet

That must be good for 190 +

 

true.

what about acceleration??? i've been out in a few supercars and i have to say i'd spen a lot on getting it to accelerate hard all the way till it runs out of steam

 

ok so who knows then facts then?

whats the top ten fastest top speed.

whats the top ten fastest 0-60

bit hard to do track because they havent all been round the same track.

i know you should include 60-160 or similar but that will be hard to find as well i suppose.

 

i think martin is going close the gap quite a bit,but i also think when rods is done its gonna be moved on a bit more

 

Whats Surge got to do with topspeed?!??!?!?!?!?

does anyone have a Cossie that does 180mph at 4,000rpm?!?!?

 

Top speed will be Rod.

Acceleration - Kev Sharp still have it, or did Martin beat on the old engine?

Track - will be Reyland 3 door (after Gareth Lloyd, AM Sport cars, Scotty's WRC car etc) as it's the only one competing in Time Attack at the moment.

 

You're right Euan, it's defo not all about top speed. Fair play to those that like it, but it ain't my cup of tea. The 2 top speed runs I did at the Daddy Thrash will be my only ones, even though I did 182.9mph on road wheels and tyres, my car's spec and set up is purely for track. It was a bonus though getting that speed and being one of the few that have achieved over 180mph.

 

i have kevs engine in my car now!

but i dont have 4wd or seven gears

 

thats probaly spot on i reckon but i think martins old car took the o-60

 

wont be accelerating very quick while its surging...

 

186 mph just with the electronic limiter removed.....otherwise totally standard......Ooops, I just remembered it's not a Cossie...........

 

But it's still producing the boost and the engine is consuming all the air it can until it gets past the surge point and the VE increases.

 

mine goes well goes of the clocks nee bother dont no how accurate they are mind
dont know my 0-60 cos ive snapped 6 shafts doing full on launches so i give up on that
and it handles pretty well to

 

your cheating Jim

 

Choo CHOO

 

Yes but that boost is in fact stalling the turbo until the extra air can be consumed, so acceleration suffers, which in the confines of say brunters is what you need in order to reach the top speeds in the given distance. IF you had unlimited road or private test track, then the loss of acceleration wont be such a problem

Thats how i understand it anyway

 

Totally disagree. Surely any car will pull through the surge quite quickly and it will have very little effect... or on a real top speed effort you will be reving the nuts of it in every gear so you won't get even get surge....


To get to 180mph in a Cossie you are going to be hard on the throttle for a long while with the revs at over 70000rpm.... how the hell can you have surge at 7000rpm on any sensible turbo??

Charge temps have the biggest effect on Topspeed efforts in my limited experience....

 

im just wondering with all these top speeds written on here, are they the maximum top speed avaliable.

the reason i ask is most people watched james may in the bugatti, once he got to 240mph, look how long it took him to get the 12mph on top of that, if it were at all possible to hire it from VW(not likely) then i think its possible for alot of cars on here to go alot faster

 

Sorry mate... thats bollox.

My Turbo surges its nuts off at the moment under 5000rpm... BUT it Will still do an 11 sec 1/4. Is that not accelerating hard enough for you?

When you are REALLY flooring a car in a straight line, surge has a very very limited affect in my opinion.... you just are not in the surge zone for long enough for it to make a difference!

 

I like cheating........

I'm sure both Stu and Karl have some comments on Turbo Surge......

 

Fair point Lee, but if you stopped your turbo surging under 5k then you would do the 1/4 quikcer than 11 sec which as i said in the confines of somewhere like brunters accleration MUST play a part in reaching the desired top speed

 

The theoretical top speed is a combination of drag, power and transmission ratios, given an unlimited distance (like a banked circuit), I am sure the transmission could be changed such that higher speeds can be attained over a longer distance for a given amount of power/drag.

My understanding (in Rod's case) is that there is limited space to achieve top speed, so gearing has to take into account the fact that you need to get up to speed in a short distance, as well as reach a high final speed, altering gearing for a higher speed might affect the car's ability to get there in time, thus requiring more power/torque to get going in the first place.

The final problem is that engine would have to stand sustained high revs for a prolonged period of time and would have to be designed for that purpose And let's face it, not everyone's got VW's budget for design and engineering

 

Not at all because You don't GET surge when REALLY on it mate.... because when you rev the engine to 8300rpm, when you change gear you are out of the surge zone already!!!!

 

Again, good point but your car surges below 5k yes? What about cars that surge above 5k? If your car surges acceleartion must be affected otherwise no one would try and overcome surge by capping boost and changing turbo's. And acceleration must play a part in reaching top speed in confined spaces surely

But thats is only a small point. Like you said ACT's are what hinders a lot of top speed runs
