Crown wheel and pinion is hewland engineering one but there too small and not strong enough. And yes the box is a big tooth in a t5 case I'll have to see how it go's ade ran one with 680bhp but the new turbos make more torque and sooner

nixon_2wd

Have you decided what diff to use, ajamesc?

ajamesc

I've a supra diff with a billet rear cover billet mount wier up rate kit on an mk rear beam with solid mounts there's a pic on my engine thread

nixon_2wd

Awesome! How much is the diff kit from MK?

ajamesc

It was a while ago now but the fitting kit was about 500 I've an mt rear cover wier kit and rebuild was 600. I got my beam for a grand

Hellraiser

I'm lookin for similar power James, I've got 10 long studded 200 block, which I'm gonna have linered by Mark at mad also. I've got std std crank, CP pistons also Carillo8mm longer rods that Mark got me. After block I'll be sending head to be done to Marks spec n cams to suit. Then turbo n manifold to Marks spec, n Ecu of his choice as he the one I want to map it. I've got 6deg rear beam to go on, bladed roll bar, supra diff,also fitted with weir kit n overhauled by Bara. Coil overs, 320mm discs n rotors 4x4 calipers on rear. I'm having billet hubs on front along with bladed roll bar adj tca's and comp struts all from Mk with the huge front brakes of nicks rs500 (reylands old car) n I've purchased brand new Tremec from Martin with hydraulic clutch so I'm hoping as everything new it'll all handle the power . Lots of money spent i know but I don't drink or smoke got to have some enjoyment, I want to do it right n right first time

smiley

Will make for a good thrash when were all done

Rod-Tarry

You beat me to that statement would be good to see these 650+bhp cars strutting there stuff but I think those days are gone but I hope im wrong. I would love to see a gaggle of these cars at a Vmax event.

turbotrev

I would love to attend some kind of Cosworth group thrash, that'd be awesome!

Not really vmax though as that's just top speed.
I have a lower gearing so would max out at 160/170 ish anyway.
I could possibly change that I suppose if I needed too

Cheers Paul

smiley

Like the old days but with modern set ups it would be a crime against the scene not to I've got a way to go with mine still in fabrication but once complete everything else should come together pretty quickly as have had time to save my pennies we will still need a head start though mate

smiley

I will also be limited to around that with oplligger long box and 3.9 supra diff I would like to see what it could do with different gearing I've got a spare box what would be a man enough rear dif for a 4x4 for top speed with correct ratio? This would be something to look forward to once the cars completed on a low ratio low lag responsive set up

Caddyshack

Mine is only going to be 530 bhp I think and 470 now, also limited by gearing but it would be good even to clock it at 160mph verified to be honest. Might be good to see how quick they get there. 170 mph is pretty fast at brunters.

Rod-Tarry

Any Cossie bash would not see mine wanting to attend but I would like to get involved. My dream is elsewhere a bash at the Roosh Ford GT as we are the 2 fastest Fords in the UK as we end 2015.

smiley

Make sure we know when they happens id like to see that

Caddyshack

Why wouldn't you want to go to a Cossie bash? Surelyn that is what you often say you miss?

Hellraiser

I'd be up for it once car done definitely

Adam-M

I'll search that crown wheel and pinion for my gripper but mines will never go over 450bhp. Sorry if I missed it did you have one of these crown wheels or did you wreck the standard one?

ajamesc

I took all the teeth of a standard one flooring it in 2nd coming off a roundabout lol it gripped no wheel spin at all and just went bang. I got the c.w.p done by a mates dad who worked there. It was shot peened and super finished by them

Rod-Tarry

I miss it but not to attend anymore. Think my car has proved its point being fastest Sapphire since 2002 & fastest RS Cosworth since 2004 its the time of others now.

smiley

Thanks for handing me your title rod "come on then lads LETS AVIT!!!"

Adam-M

Fucking hell lol, so even after shot peening it still couldn't take the power lol

turbotrev

What kinda power was it that destroyed it out of interest mate?

Cheers Paul

ajamesc

About 500 with around the same torque. It was the r888's that did it lol it would spin before I fitted them

turbotrev

Jesus!!! Not good!
Was that in its previous engine spec before it let go?

Cheers Paul

ajamesc

Yes it was as the engine was before I broke it. First off I broke the diff so fitted the gripper then I broke the crown wheel and pinion. That's when I rebuilt it with the up rated crown wheel and pinion. Not taking the risk with it in the new engine so as its worth about a grand it's a no brainier to fit a supra one and sell it

turbotrev

Sounds good.
Yet to see a broken supra diff.....

Does anyone know if gt35's or gt40's come in twin scroll?

Cheers Paul

Mark Shead

Havent I already said they do, A GT35 needs a atp housing to convert it to. The GT4088 comes in two diff housing options.

Mark

turbotrev

Not sure....
But thanks for clearing that up

Cheers Paul

Will be some good spec cars around shortly by the looks. I'm not going to compete with you lot but would love to have a go at top speed if there was ever another thrash, mine should be 550hp + gas.
Rod, what happens to the big power sure it was meant to be 800+hp escort Cossie that mark was doing for a customer a few years back? Sure he was going to have a go at top speed.

stevieturbo

Straightliners run various events over the year for top speed. Usually standing mile format, although looks like they may have a couple of longer events at Pendine and Pembrey for 2016 from their FB page open to cars and bikes.

Rod-Tarry

Two come to mind. Ranj was going to have an engine the same as mine but it didn't get completed & im using his as yet unused DKR crank in my new build. The other was Dave Moss but his was around 660bhp it ran 194.2 mph at Bruntingthorpe many years back. I hope these big power road cars do happen as this scene needs boundaries to be pushed again.

Sounds good both pendine and pembrey are local to me which would be good but don't think there's a stretch long enough at pembrey and it's a rough old place. Il have a look on the website.

lee2cossies

iTrader: (2)

Not either of them rod, this one there was a bit about it on here and a bit about it in fast ford when they ran a feature on marks place few years back. All I can remember is it had similar spec to your 800hp engine with individual throttle bodies, il try dig the mag out.

ajamesc

There was a huge spec escort that got broke not long ago. It had the engine from yum in it I think the guy decided he had too much money in it. I have the breather system off it

Caddyshack

That's right, I think he broke it up after the gearbox let go. I remember him saying how quick it was.

ajamesc

It had a twin scroll set up think it was well over 600bhp I remember he took it off the road after breaking the diff.

Caddyshack

Oh, it was the diff, not the box.

It does seem that a fair amount of cars get broken up shortly after being finished.

ajamesc

Ill not break mine I'm on a life sentence

lee2cossies

iTrader: (2)

That was turbomooks car not the one I'm talking about. Almost bought the engine out of it before turbomook had it. The engines now in a rs1600i I think. It's a shame all the big power cars seem to get broke.

Adam-M

Andrew Gallagher has an 800bhp escos don't know the spec of it but I very much doubt he'll do any top speed runs he's more of a drifter and circuit driver.
