Hello
what is a good setup for 500 hp / atw?

NEIL A

This plus a free flowing exhaust and T4 or gt35

A Chevy LS series V8!

El Grand Tomismola

Basically a fair bit of money

MatthiasBoldt

garrett t4 or gt30r?

Both will get you there on a suitably specced engine

Mark Shead

ATF is easy, ATW is much harder.

Mark

rapidcossie

prob would struggle to get 500 ATW from a GT30 specially if it was 4x4

MatthiasBoldt

its a 2wd

NEIL A

In that case a similar spec to what i posted above has been proven to do 500 atw with a wide power band.

rapidcossie

Buy Neils engine, its much cheaper than trying to build your own

Clikettman

good head, 2 BD14, a GT3076r and a good remap...

did,nt think 2 bd14s would do 500bhp

col cos1

iTrader: (5)

we will soon see

cossiedave

iTrader: (1)

let us know then m8 as i have a 16 and a 14 but want to get more driveability would think 2 bd14s would be that

col cos1

iTrader: (5)

my car is currently 470bhp dave so id think my recent mods will take it up to 450@wheels so a realistic 500bhp

or going by dastek rolling roads my car was near 500bhp a good while ago with nowhere near the mods it has now

cossiedave

iTrader: (1)

so if mine is 497 atw that makes mine over 500bhp then m8 ya sweet it is hard to get 500bhp atw with a 4x4

col cos1

iTrader: (5)

if yours is 497@wheels and 4x4 thats a fukn fast car

cossiedave

iTrader: (1)

it is fukn fast m8 but you know what its like we allways want more i just need to get a gearbox now as it keeps smashing 3rd gear out but fun whil it lasts

col cos1

iTrader: (5)

my mate has been doing the same and his only 360-380@ at crank,why dont you buy neils box?

Mike Rainbird

iTrader: (3)

That would not achieve 500bhp at the wheels.....

MatthiasBoldt

please,back to the tread,what is better?
t4 with ballbearing our gt30r
and the other parts:
bd 16s
swedish plenum
7.2 pistons
H rods
flowed head
6 long headbolts
ect.
its real with this setup?

sorry for my bad english,im from german

Cragrat

iTrader: (4)

thats not your fault mate its better than my german

col cos1

iTrader: (5)

spec sounds good but t4 all the way imo

Bart

I think the T4 BB and GT3076R are both good turbo's so i would go for the cheapest solution.

tore_tj

that'll be the gt30 then.. but that's not gonna make 500atw

Bart

The biggest GT30 will do this IMO. I think it's the GT3082R which is rated to 600BHP.

tore_tj

On a 2litre cosworth? well we'll see about that. I'll post my figures come may/june..

pa_sjo

What do you mean by 'best'? What is your criteria? Best price, best response, best what?

Mike Rainbird

iTrader: (3)

I've never heard of that turbo?

Are you sure you're not getting confused with the GT3076R wth 0.82 a/r housing or a GT3582R?

tore_tj

3076 will struggle with 500atw if 4wd imo

Bart

No, this is from ATP website:
Dual Ball Bearing "GT30/GT40R" Turbo assembly. T3 style inlet flange with 4 bolt T31 style exit. This turbo incorporates the same exact GT40 compressor wheel found in the popular GT35/40R, but runs the smaller 60mm w/84 trim turbine wheel from the GT30R. Appropriate for smaller engine where the GT35/40R feels too big, but the high amount of compressor flow is needed for the desired HP and boost levels. Large T04S style compressor housing with 4.00 inlet and 2.50" outlet. This turbo has a flow capacity of about 600HP.

Turbine
-Wheel: 60mm w/ 84 trim
-Housing: .63 ar, .82 ar, 1.06 ar
-Maps

Compressor
-Wheel: 82mm w/ 56 trim
-Housing: .70

tore_tj

flow capacity of about 600bhp if you've got the ideal setup I still believe you'd have to go gt35 for 600bhp on a cosworth. Would be interesting to see a dyno print with that gt30.

cossiemanden

560 bhp IS achived on the cranck by a cossie engine with a gt30.
and 734bhp IS achived by a gt35 so it is possible
What i´m wondering about is that everybody talk about drivabillity???
Drivabillity and a 500+ cossie engine is long gone, with that much hp you can only make it as good as possible, but drivable, no.

tore_tj

not driveable? I just read about AJC's car in fastford and iirc that was described as the ultimate roadcar. Porkies 3dr was driven by his mother afaik with ease so I guess they can be made driveable if you know how to spec.

I don't want to disagree to much about the numbers claimed here but I guess they are dyno numbers? I recently read about a GT30 escort here in Norway. 520+ flywheel bhp on the dyno. It made around 400 atw when the car hit the rollers..
That was a 3076 iirc.

Of course it comes down to what's hooked up to the dyno, ic, exhaust etc.. I'd like to see the graphs if someone's got them?

And to be clear: I'm not arguing it can be done, I've just haven't seen the results
And we are talking ATW figures here..

El Grand Tomismola

Andy's car power delivery is so smooth you don't relise your going that fast until you look at the clocks.

I watch him do his 11.9 at Pod this summer (from inside the tower, which was well cool!!) and i have seen his car on the road. The setup allows the car to be driveable but also insane when he wants it.

Actually - I need a passenger ride!!!!!!!!

tore_tj

That's what I'm after too. Perfect cossie imo

cossiemanden

Tore: i know what you mean, but a real 500+ engine is not drivable as a 330kit engine, that´s what i mean.
My girlfriend drowe my wild spec gt35 cossie in high heels without any truble, but there is NO power until u rev it past 3500rpm, and then it only comes slowly.
Drivable is not unstable standstill @ 1200rpm, clutch that is on/off etc etc
I know a gt30 is WAY better spool up, but to make 500 genuine horses it takes some spec of an engine.
And yes, andy´s is a good one to bring up, and only on bd14´s also

tore_tj

True

3i_gaz

yeah andy (AJC) has got an immense escos, as tom said you wont believe how smooth the power delivery is until you actually go in it, i couldent believe how much more driveable and smoother the GT30 seemed compared to a T4.
