Thanks to Stu & Karl we have a unique chance to find out just how much power a "standard" YB engine can produce with JUST the following mods:

Big Turbo
Big Injectors
Wire rung block
Thats it!

Stu & Karl will build and mapp the engine to produge BIG power!!

Looking for parts donated to make this project work by keep costs down.

We may even raffle the finished engine within PassionFord!

Post up your thoughts on here please

========================================

 

is this just before it "lets go" or before you run out of money/donated parts

 

great idea, sounds like fun too

 

And how will they measure the power it makes .

 

Sounds Cool

When was this all decided????????????

 

Which thread we gonna use? This or the Brom one?

Heres what i said on the other one (particularly the "rules" regarding spec which ive highlighted in BOLD)

IMHO providing the turbo is specced correctly (esp the exhaust housing is particulaly unrestrictive) is wont surge if done right.

Right then, a PF raffle type thing is a good idea for this i reckon Entry by donation or summat.

BUT the spec...

IMO it should be standard YB internals barring headgasket and/or wire rung block.

ALL bolt on parts (manifolds, turbos, and so on) total free for all, L8 ECU for fuel and ign, but boost control can be let to whatever we like (ONLY people whod want no boost control, or std only, is people who WANT them to fail, ie Phil )

Thats how they do it in USA etc and often get 600+bhp from std 2litre 4cyls.

I reckon it wont be a bad engine...

Drive like a std cossie off boost, but go like the fucking clappers. Will be a race fuel only type thing i reckon to make sure there no det (as thats what will kill this engine), and how long it lasts im not sure (will be pistons if anything, the rest of the YB is spot on really), but i reckon itl be impressive...

And probably make people change their ideas on cossie engine spec too...

 

So doug WHICH FUCKING standard YB version can they use?

RS500

2WD

4X4

ESCOS

 

Deffo as Steve says - completelly STANDARD internals/mainfolds!!!

The whole idea is to "discover" what a YB is capable of power wise with BIG turbo/Injectors..thats all (the wire rung block being the only other "trick" part)

 

a fookin interesting project !

 

It dont matter - Let Karl & Stu decide that! It's their engine project

==============================================

 

Well it does...as the RS500 is the only version that could produce the most bhp!

 

should be 200 block (as commonly available) not sure on rest

 

hmmmmmmmm

 

actually running 2wd inlet and 4x4 ex manifold

 

and 2wd cooler

 

To fill in the newbies...

Myself and Karl were discussing the possibilities one evening of throwing together a std YB lump and bolting ona fooking large turbo, just to see what power could be achieved before fundamental restrictions got in the way... IE: Compression, Port size etc....

We just thought it would be interesting to do it and hadnt discussed any "Laws" just that we would like to use an essentially std YB crank, rods, pistons, block, head and compression ratio. Manifolds i feel could and should be changed to utilise fully our chosen turbocharger and powerband, otherwise we may as well stick a T4 on and make 440bhp.. lol. Rpm is another issue with std valvetrain so may dictate turbocharger trim sizes. (8K absolute max im thinking initially due to valvetrain... or shall we go solid cos its easy.. lol)

Anyway...
It was simply an idea, over beers, it was mentioned on PF about an hour ago, and now we have folk making up whole new laws for our plan.. No boost control, smallest manifolds possible, opel nove ideally, T4... anything to make the plan pointless or fail... go IMA

The biggest problem instantly posed to us was cash.. who was to fund it.... That problem still exists.. roflol IMA?

 

Danny,
In that case, Phil's guess at 440bhp earlier on, would be pretty much spot on .

 

hands in pockets ppl raffle styleeeeee

 

i know mike thats y i put em all up its about what a standard engine will produce etc so i feel manifolds can be changed

 

440bhp....prouduced in 2500rpm power band with 1500 of those RPM surging

 

How about if you used my std engine as a base. Its only a wee stg 1 Its done 78,000miles though

 

Are you willing to lose it Paul? Seriously?

 

I dont see anywhere where we mentioned letting you have a hand in assembling or speccing it, so i dont foresee that happening....

 

The main good point of this expererment is that it will REALLY show how effective bolt on parts can be.

When it comes down to it, fitting bolt on parts (inc manifolds) are an easy DIY job, and hence relativley cheap (as its labour that costs the real money), tuning engines only gets REALLY expensive once you go internal.

This is why its so common in the USA, esp with Jap stuff, Supras, SXs, EVOs, Skylines, etc to go bigtime on the bolt-ons with std internals, and they get mental power n results.

There been 1000bhp@Wheels Supras with std bottomends.
There been 9sec supras on std bottomends.
There been low 10sec GTRs on 100% std engines.
There been 750+bhp@Wheels GTRs on 100% std engines.

Mental turbos, mental manifolds, whatever, who cares, nothing compared to the cost of a full engine build.

Look at this for example....

ATP Turbos in america, they ALWAYS doing these standard engine projects...

Heres there Audi A4 1.8Turbo project
http://www.atpturbo.com/root/releases/release050304.htm

STANDARD engine, 1.8litre, 11.97quartermile at 121mph!
Over 400lb/ft by 4500rpm!
426bhp at the WHEELS, and its 4wd so over 500@flywheel.

All engine components including engine block, cylinder head, cams, etc. remain stock. Only reprogramming of the stock ECU along with larger injectors were required to accomodate the additional horsepower.

This is AT THE WHEELS power



Heres thier EVO8 project---

Engine is completely stock with the exception of a 3.00" exhaust system to compliment the 3.00" Stainless downpipe included in the kit. Stock airbox, stock front mounted intercooler, and stock cams are all retained. Fueling is done via 660cc injectors and a custom tuned standard ECU.

POWER AT THE WHEELS (4wd remember


And ATP arnt even going all out like Karl n Stui were planning, they try n keep the car reliable and useable.

I think Karl n Stus aims are to build an all out screamer to pull a good bhp figure, not worry too much about lag and reliability

 

Nice grown up reply that mate ....you lost your sense of humour?

 

it makes sense standard manifolds carnt be used
for 1 a gt35 or bigger will not fit on standrd manifold so it needs modding to work so its not standard
so from the start do we devine standard internals and sizes so basicly a blue printed engine

 

Good luck to all involved

 

My engine is standard apart from the WRC gasket

 

Steve there is a guy in rallycross thats running 8.5-1 with 800bhp on a std YB bottom end!!!!!......I wonder how people arrived that a std bottom end is only good for a certain BHP limit?.....Obviously if your having to pay a tuner,i guess 500bhp is the most they'd risk which is understandale.......

So Stu the BEST plan would be to just use a std bottom end using the 200 block to see how much bhp it could withstand before the crank snaps...thats a more valuable test imo.

 

can't wait to see the result of this, will be interesting to see!

 

could someone explain what a wire rung block is please?

 

and there will be no 3bar map sensor also

 

Really?

Its like i always say, not just in YBs but cars in general (the UK GTR "scene" is classic for it), people upgrade to a stronger part without knowing (or being anywhere near) where the limit of the std one is.

I mean, anyone broke a crank or rod on a road going cossie that WASNT due to an oil issue? (Or a det issue, if det can bend rods...)

 

Brom

I agree the manifolds will have to suit the chosen turbo........

But it's best to let Karl & Stu will decide on the spec/parts used
throughout this project

 

why use a wire rung block, why not just go for a cometic 3layer gasket as nowerdays seems the "norm" for most as it doesnt need any machining of the block etc.

wire ringing is where a small groove is machined out of the block and c shape lengths of wire are dropped in them, these when the gasket is in and the head is clampled down supposidly give a better seal to high boost pressures, but personally, anytihg that is efectivly crimping the gasket is going to weaken it , i know there are big power cras running with them, but in todays world, would not a decent proper headgasket alone suffice?

 

If I had a spare car then yes, I'd give it a go. But i use the cossie at least once a week, and I assume this would all be dyno work, and not something that can be done step by step at weekends? as I'm about an hour from Karl.

Paul

 

Well its about power only as far as i can see so wont take a genius to work out what manifolds n intercooler will do the job for as little money as poss- MikeR "sweedish" inlet, adapted std 2wd exhaust man, and either some aftermarket RS500 cooler, or 4 2wds welded together.

For a cheap turbo, tho i dont trust their reliability at all as ive never heard of them being tested, theres a Brazilian turbo manufacturer called "Master Power" who make and sell huge turbos for fuck all money... Id be VERY interested to see how they perform...

 

yes doug i agree am not getting invloved
lol
i will run this 4x4 engine of mine into the ground over xmas waitin for my new engine bits

 

Yeah, its deffo not a day or 2 Job Paul..

When i say lose it though, i meant physically... we wont know what the limit is until we exceed it... unless we are lucky enough to spot the signs early...

 

That can be your donation then Stevie.. top man.. great offer
