There’s a US engine builder calming to built a 700bhp zetec engine on a budget. I think he is talking a load of BS but don’t know zetec engines well at all to call him out on it. The builder is being a complete ass and not telling anyone the spec and has not published the dyno result but a few people have claimed to have seen the dyno result and say it is legit. Is it possible to build a 700bhp zetec turbo? Also what sort of cost would be involved and parts?

everythigns possible mate ,

theres at least two zetecs in the uk with over 500 hp , both lads frequents this site, im sure they can help with specifics regarding prices ,

as for 700 hp .

could be done , if hes running it on race fuel and fuck off hugeeee turbo , slam a bucket load of boost through in one spike ,

it will make the numbers , but may not be useable ,

see what you can dig up over the pond fella

try searches on the web ect , if its a tuner it my be on youtube ,

quick search revealed this ,
http://www.focusfanatics.com/forum/s...d.php?t=205671

they mention a 700 hp zetec ,

but i only looked on first page ,


maybe you could read the rest ,

pps the first pic is andy gallachers new cosworth engine ,

and a few posts down they mention rod tarrys moster cossie engine aswell


both users on this site matey

I seem to remember there being some very big power zetecs over there years ago.

I wouldn't be supprised. They managed to get 1200 bhp out of a vauxhall ecotec for drag racing.

Thanks for the replay.

LOL, I am the user by the name of "English" on that thread. If you read all the pages the user 1turbofocus (Tom) is the one who claims he made 700bhp. I understand if you put enough money into a project you would get the results your after, but the user 1turbofocus (Tom) I just feel is bull shi*ing the questions he is being asked.

Also he say 800bhp out of a yb doesn't impress to him as he has made over 700bhp out of a zetec but wont post the engine spec or dyno.

Ever since I’ve moved to the US most message boards I’ve joined are full of bull shi*ers and this one I’m finding hard to believe as he is a respected zetec tuner in the US so I am not sure what to believe.

half way down that page post by focus_3xz mentions somebody called Shaun Carlson
and a 1000bhp zetec anybody ever heard about that before?

gareths09

That car was on ebay for sale not so long ago but not sure how true those numbers are.

creator

it sounds crazy if it was anywhere near correct tho.not sure how reliable it would be tho

gareths09

That is a full blow drag car so it does only have to last 10 seconds or so.

I can think of no good reason why a Zetec shouldnt make 700bhp if appropriately modified, plenty of other similar engines do.

This focus has never been 700hp ..
A quarter-mile time of 10.9 in the 134 mph
automatic transmission ...


funny

then I'm 1000hp

Chip

iTrader: (3)

Still making good power if its doing 134mph on the quarter

If its a 1000kg car then its gotta be over 500bhp I would think to make that sort of terminal, especially as auto transmissions sap more power than manual.

What does it weigh?
If its 1200kg+ then its gotta be 600bhp at least I should think

AustenW

Some of the rallycross cars were running about 660bhp with the zetec motor a few years ago in the UK.

If they use the ST170 / SVT engine they could get the numbers but the head would start to lift off the block above 600 unless they redrilled the block and installed thicker head studs.

At that sort of level you need to have a big budget motor, no question or it will last 2 mins.

Thats the key thing, making 700bhp isnt actually that hard, making it reliable is when it starts costing!

700bhp on a stock crank????

Chip

iTrader: (3)

Cranks rarely just snap instantly through power, they just die exponentially more quickly as a result of the flex, I dont doubt that the crank could take 700bhp for a short duration.

gareths09

So what do you all think...700bhp can be made but not for very long??

xr-stu

isnt it standard assumtion that 450bhp is the limit for the standard crank?

szabyk RST

iTrader: (1)

OK
I believe it is 600 hp

.. but not 700 WHP (800 crank)

I do not think so .....

Chip

iTrader: (3)

For how long?
At what torque?
At what rpm?


Cause if you think all 450bhp engines put the same strain on the crank, you are mistaken.

My hungarian is a little rusty mate, lol

Chip

Unless it weighs getting on for 2000kg (I havent seen the car in question) then I would agree with you on that one mate if its doing 134 terminals.

Specky did 138mph in his tigra on 505bhp

why???

afew more clues

Wow, this one claiming 1000bhp certainly LOOKS like it would make that sort of power

szabyk RST

iTrader: (1)

i run 1000ccm injectors....2008..

95% D.C(8k RPM)......550Hp.....

now run 1600ccm

and I am not 800HP .....

maybe 600-650...

Chip

iTrader: (3)

He'd need to be about at about 5 bar static fuel pressure on those injectors to see that power, lol

szabyk RST

iTrader: (1)

1600ccm injectors, so now there are runs on E85

Chip

iTrader: (3)

1600cc on E85 equates to similar power potential to 1200cc on traditional race fuel, due to the lower calorofic value of E85

Rick

I'm not familiar with running auto transmissions on a chassis Dyno, but he claims that they couldn't get a torque figure, and the dyno plot supposedly shows power vs elapsed time, not rpm. Now as a dyno works by measuring torque...

Chip

iTrader: (3)

A rolling works by measuring torque at the drum.
Then the RPM of the engine is used to translate between that figure and torque at the engine by taking the gearing out of the equation.

If they didnt have an RPM signal from the engine, they could still plot power, based on the torque and rpm of the drum, but they couldnt plot engine torque or engine power versus engine rpm

So it sounds perfectly reasonable to me that you could end up in that situation

yes..

iTrader: (6)

for me id be worried its making 700 hp on stock cams ??


surely that aint right lol

szabyk RST

iTrader: (1)

never

I run:
274 / 266°

10.90 / 10.45mm

2 bar boost...GT35/40R

may be, I do not do something well

Chip

iTrader: (3)

MADrod did 206mph with 900bhp or so on an exhaust cam milder than that IIRC

Cams factory running?
