So the 'top speed record' for escort rs turbos.. is this only valid if the engine is a 1.6 CVH? What about a 1.6 Zetec?

I'm tempted to have a go, if a 16v engine of equal displacement is acceptable, but I certainly wouldn't want to throw a lot of money at a project for it to be discounted

Im pretty sure Escort RS Turbo wise its 1.6cvh turbo only.

Although it would seem for the Fiestas most recorded are zetec powered.

Rab

It just needs to be an Escort as far as I can tell. It just so happens the fastest ones are CVH powered!

IIRC Ollie had a 1.9 CVH for a while....

pa_sjo

Hmm that's a shame. There isn't really a 'rule' as such though is there, the current and most recent erst top speed holder exceeds 1.6L displacement doesn't he?

Jim Galbally

there's nothing official, not like it's in the guiness book of records, so it doesnt really matter to anyone other than your peers IMHO

Rab

BTW, tuning a 1600 zetec to the power levels required for a decent top speed are ridiculous. Turbo'd or not. The 1600 zetec is practically and untunable engine.....

pa_sjo

Rab, it wouldn't necessarily be a 1.6 Zetec, but a Zetec of 1.6L displacement

Rab

Thats an entirely different kettle of rabbit dung then!!

Do tell me more!

In PM if it's all a big secret

foreigneRS

it wouldn't seem fair to compare a 16v to an 8v, even if they are the same displacement. you know as well as anybody that the extra flow capability of the extra valves gives an advantage, so you might as well be using a 1700 cvh or whatever.

are you thinking of doing something short stroke for high rpm power using the large bore to get a big valve area?

either way, it's always good to see others go for top speed runs and what they can achieve

pa_sjo

foreigneRS- for a few years i've contemplated building a de-stroked 1800cc zetec, to run relatively low boost but high rpm (say 9k).. sorting the crank/rods/pistons is the easy part - the head is the tricky area!!

Rab

As far as I can tell, then engine just has to be in an Escort....

I mean, still needs to be a Ford engine of course, but doesn't say anywhere it has to be a CVH or it doesn't count......

sounds interesting

i may be wrong but i thought that ollies car when it set the current record had a 1.6?

Turbocabbie

I think the record for fwd escorts and escort rs turbos are two different things.

Its the CVH Turbo that makes the car the RS..... take away the turbo cvh which was only available in that model and its an Escort Turbo

its like asking why are we not counting YB engined escorts as its never been clarified that you have to drive the front wheels

Tim

Think most of us christian ollie me etc all had 1.6 last time ollies block was 1 of mine which he has now kept lol ,,

Tony we thought of the yb but the cvh just seems to be getting faster and faster lol.

I recon 160 plus takes some doin in an escort whatever mota u have let alone 170 plus lol ,dont seem to be many done it imo.
tim

Linsay

agreed - Think people have a lot of respect for getting the best from the engine which came in the car

pa_sjo

Some interesting comments, keep 'em coming


With regards to the YB argument, yeah I guess that's fair. I suppose it depends on what you're trying to beat - the only ERST top speed records on PF, as far as i'm aware, are based on 1.6 CVH's. Would attempting the same thing but with a 16v engine suddenly put it into an 'anything goes' category? It's a tricky one - I don't want to build something that someone will come along with a 800hp v8 in and trash it 6 months later

I suppose a fair question would be to the current top speed holder and the previous one; would you happily admit 'defeat' if a 1.6 16v erst beat you or would you claim it's not a fair competition?

CVH RST's should compete for top speed, Anyone can build a 350bhp ZT, not everyone can build a '350' spec CVH.

pa_sjo

Well sure, but there are limits. I don't think anyone has gotten over 350bhp with a CVH head as there simply isn't enough material in the head to port it enough, so that's kinda a dead stop. Is it worth spending a lot of money building a fine-line CVH at 350bhp in the chance that it may just pip the specific record, or perhaps try something different that is equally as-cool?

Charlie Chalk

Christians made 351bhp.

hats of to all you top speed chaps

who thought 170 was poss a few years back

mart rs

an tims almost 370

Turbo Zetec

and M K's zvh made over 400 didn't it?

vroooom ptssssh

i once heard of a 800bhp 1.6CVH...think it was on ebay or something

Charlie Chalk

iTrader: (1)

He never had a ZVH, Field Motorsport done a ZVH that was meant to have made 410bhp.....

On gas.

For me the attraction is doing it with the proper engine. Mine actually has the block the it rolled out of the factory with and the original crank that is to this day unmachined.

As others have said, as soon as you take away the originality aspect, you might aswell fit a totally different engine. Why not put an Evo lump in there??

Whatever the case, in my mind, my competition is only 1600cc CVH's within their normal accepted terms (so obviously the minor overbores are not significant.

Thats my take on it anyway.

purple_fiesta

aslong as its a ford lump and front wheel drive imo

tabetha

Throw enough money at it and someone will beat it, as others have years ago, Peicher & Voln for one.

yes but a yb engine will make more power by doing nothing more than a chip and some injectors

Christian and Beccy

iTrader: (14)

Same could be said of a YB. Why piss around with that when there are other engines out there that are far more capable? It's a challenge to tune the original engine. Thats why I do, not sure about others reasons.

I would be interested to see the list of these engines
