Came across this on the web, saff cossie with 1300hp!!!
From Sweden, S&J block, Farndon crank, 2lt, PT8385 turbo 💪🏻💪🏻

The UK number chasers will need to up their game.... 😂😂

Cheers Paul

 

Jesus wept 😮😮 that's gotta be on methanol 650 hp per litre is mind blowing

Is there any dyno plots or times for it ?

 

Wow that would be a bloody handful! Emphasis on the bloody!

 

Anymore details on it? S&j head?

 

Definately the way forward these s and j blocks, if mine ever fails and is not repairable il be changeing over to one for sure

Looks on the plot to be 8800 rpm max I thought it might be higher than that it's huge power for sure, must be on some seriously hot fuel, cylinder pressures must be enormous 😮😮

I've looked up the turbo they appear to be like a beefed up gt42 size rated to 1400 hp 😮
must have some sort of anti lag id imagine to spool that beast

 

There was a video on Facebook that showed the graph sure it was nothing till about 7000 odd then a straight line up lol must be a drag engine

 

I'd imagine so mate, it's incredible to hit that sort of power though it's right up there like the 3000 hp gtrs 💪

Do you have a link pal ?

 

Drag engine??
Its a road car with a high up yb engine, like all saffs 👍🏻

Cheers Paul

 

Hardly see a stripped out race car the same as a full interior and a stereo car that makes power from 4000 odd rpm as being the same lol. You do have a real problem with high horse power yb’s don’t you lol. Maybe Carl will take you out in it as a road car so you can see what its actually capable of. If he like most knows how to use the gear box up on on the move guess what you can actually keep over 5000rpm lol

 

I've not seen the curve but if it is 7000 - 8800 rpm them yes it is 100% a drag engine flat out or nothing

 

It’s on Facebook on a group called retobeutes I don’t know how to add links to Facebook on here.

 

Explain this problem you say I have about high hp yb’s then?
Because I don’t have any problems my end....

Ive been out in big hp road cossies and know what they are like thanks, so even if Carl made that offer I’m afraid I’d decline.

Seems every cossie is a road car these days on this forum wether it’s 300hp or 800hp 🤷🏻‍♂️🤷🏻‍♂️
Or is that a club just applicable if you have an efr turbo because of their low lag? Lol

Cheers Paul

 

 

 

Cheers lads found it now

Definately a drag engine



3.6 bar of boost, 52 psi 😮
1300 hp at 8800 rpm
1255 hp at 8400 rpm
1075 hp at 8300 rpm
834 hp at 8000 rpm

That's the only data the display shows
But the curve underneath you can see the 1050+ hp curve which is 500 rpm at the end 8300-8800 rpm
8000 rpm is the middle of the on boost curve
So looks to be roughly 7000 rpm coming onto boost from what appears to be a long flat baseline curve pre 7000 rpm

​​​​​​ incredible how they've got it to gain 500 hp from 8000 to 8800 rpm 😮💪
must have a serious cylinder head on it, it's an na yb head they started with that's all the info I could find, must be huge valves, cams and ports

I wonder if anyone knows him on here, id love to know what they did to achieve it

 

No such thing as a n/a YB head as such.

Unless they're just meaning because it's a S&J head, it was n/a...but lets face it any head can be n/a or boost.

And the power is simple...big turbo lol.
The earlier videos seem to have a manual box, although I'd guess to cope with that narrow powerband it is likely an auto ?

 

I'm not sure but they specifically said they used an original yb na head not a Smith and Jones one

I guess huge turbo and head must be totally maxed out for flow
The turbine housing looks enormous on it

 

The same car was on a performance ford video years ago with 800hp running 9’s. Some jump in power be interesting too see what it does over the 1/4. Strange how they have still kept it 2.0 with the ability too up the capacity with the smith and jones block, definitely the way forward the smith and jones block.
John gambles new engine will be one too watch, should be 900hp used on the road and 1/4 mile.

 

Yeah seen hes gone full s&j looking forward to seeing that as he propper goes for it down the pod

 

2.0 smaller bores, thicker liners, stronger block.

That assumes of course it is actually still a 2.0

 

Serious car by the sounds of it 😮

 

It's not a club or anything to do with what brand the turbo is, it's having a big useable power curve which makes a car more driveable on the road.
If a car is still in full standard guise, full interior, not stupidly noisy and could be driven long distance in relative comfort, and have a power band that is big enough to be driveable then I think it's fair to say it's still a road car.
my cossie in its old spec was in rods own words not a road car anymore as it was a pig to drive, had to be thrashed to the absolute limit to be able to shift and get back in the power again, hence changeing the spec for the road which is where it's at now, a gtx4202 and race fuel was going to be used for the top speed it was going to do

But it is solely a road car now hence being tuned on pump fuel no racegas or nitrous

My new gtr I have used on the road but I wouldn't class it a road car, huge amounts of transmission noise, deafening exhaust, gearshifts set up for drag racing are very harsh I'd not want to long journeys in it would do my head in nowadays 🤣😂 lol

It can be driven on the road but it's certainly not what I would call a road car anymore it's to extreme.

 

Doesnt the extra capacity come from the s&j being taller? Do they use different sized liners also then?

 

I was being sarcastic but I guess that’s not coming across 😂😂
Never mind 🤷🏻‍♂️🤷🏻‍♂️

The passionford road legal Cosworth club, but only if your car is a certain spec and built by certain people 😂😂

Cheers Paul

 

It could be 6ft tall, if the bore and stroke are the same, the engine is the same capacity. A taller block might allow for a longer stroke, but more usually it allows people to use longer rods to achieve more desirable rod angles. ( although 6ft rods would be a bit impractical )

 

So the direct answer instead of going round the houses to the shops down the pub for a pint then back again is no and yes ffs 😂😂

 

Impressive power figure from a 4 cylinder

 

I'd say the likes of the Maltese Lixxu car is making the same sort of power if not more, although that Swedish one still appears to have a cooling system etc, and I guess can be driven. The Lixxu has the block filled and only runs coolant through the head, drag car only.

 

1300 hp from a 2 litre is just mind-blowing

For a comparison it's the equivelant of tuning a Bugatti veyron to 5200 hp 😮😮

 

What difference does it make who's built it ? Its either got driveability or it hasn't
Id happily use Tony, stu, or SCS but mark built my car so I'm sticking with mad

 

Some might think this is crazy to say but...

Is there a figure in a cossie 2.0 where you chase figures for sacrifice of enjoyment?

What I mean is, to a far lesser extent I’ve messed with imprezas and I think the sweet spot of a 2.0 STI (that revs to 8krpm) is 340bhp. At that figure you’ve got decent spool still and nearly 5krpm of full boost to enjoy.

Surely a turbo that’s on full boost in a 2.0 at 7krpm is a bit silly?

Or am I just getting old? It just doesn’t impress me and must be dog-turd to drive on anything other than the strip to say you’re the fastest ‘cossie’

It’s like getting a toffee hammer and adding a load of lead weight on the back to crack a coconut, just pick up a bigger hammer?

 

I guess it all depends on what someone wants

I think this 1300 hp yb is actually worse than you think in that regard, from the info I've seen it looks to start coming on boost at 7000 rpm, with full boost at around 8000 rpm

If would be a pig to drive I have no doubt, but it's a drag car and if it's geared right to keep it in that power it would be insanely fast for sure

I'd rather a bigger engine though personally for that kind of power, 650 hp per litre has gotta be getting up there with some of the most powerful engines ever in relation to power per litre of capacity

 

I would use all them guys too but we all know that’s not how the people on here operate

Cheers Paul

 

If it’s a drag car then the more power the better, and if you can get that power from a smaller, lighter engine then the better.

Drag car are flat out wide open so it don’t matter where it makes/comes on boost.

That power is massively impressive whatever the car is built for, those numbers are just mental. Again all depends what you after from an engine.
anyone could have 1000hp bit would you want and expensive rebuild every 1000 miles.

Power chasing is an expensive game.

This car wouldn’t be the fastest cossie, but it could be the quickest, two totally different things.

Cheers Paul

 

A 1300hp drag engine won’t last 1000miles 😂 more like 100miles that’s tech 400 passes😎.

Mark

 

If the engine has a dog box with flat shift then the very narrow power is only a problem coming off the line and the power management needed to reduce the hit in first.
I quoted for a 800hp drag engine for South Africa in a MK2 escort he thought it was too much money and spent double it trying to achieve it and had too small a power band and went slower as always fell off boost in the launch /1 gear power management.
A 1300hp engine is very cool 😎

Mark

 

I wouldn’t use any of them because mark is half an hour away and he has tuned my saff since he worked from a garage at his I believe dads house when I had 350bhp about 17 years ago lol

 

Hence why for the most part....it would really need to be an auto. Although the Lixxu car is on a Jericho/Lenco/Liberty style box. Also very light too which would help.

it'll certainly be interesting to see what it does at the strip. It should be very deep into the 8's at 170+ with that sort of power....or perhaps a little better.

 

Let’s face it the ybt is old tech now but still a good engine but compared to the honda 4 cyl they make 2300 hp plus these days,admittedly for drag racing but there’s plenty of road cars on stock K20 engines making over 600hp and rev to 8500 stock ,valves retainers and cams your up to 10k rpm plus

 

Most high ish bhp k20’s I’ve seen have the torque capped to n/a levels almost, seems most over in the U.K. don’t like to stray above 450hp/200lb ft. I’d take the 600hp figures with a pinch of salt have you seen how flimsy the standard rods and block are?
