Honestly stu, id be tempted...

85lb/min compressor flow turbo for 360quid And ive deffo seen bigger ones, for even less, let me search...

 

This is YB tuning the way it used to be
done back in the day

The likes of Dave Brodie, Graham Hathaway
would be proud of this project!

It's exactly how they found the limits of the YB
engines years ago - long before many of the
"essential" parts that are fitted to todays big
power engines were invented!

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

 

Bloody interesting this is gonna be

150quid

http://cgi.ebay.com/ebaymotors/ws/eB...937884546&rd=1
Under 300quid...

 

I'l ask Phil 2400 if he wants to donate that Bentley Turbo (Garrett)

 

Bentley turboa arnt good for much power tho if i remember right, may as well just put a T4 on it if you gonna use that

 

Interesting!

 

This is interesting as i may well bung the engine from my escos i get into the saff and just bung a GT40 on it with the Mike R plenum set of air to air and go 8 x greys and map my S8...i feel that if i modify my current map i could produce between 5500rpm to 8000rpm quite a fooking weapon...of course the flaw here is grip has i cant acheive any with current tune unless i bung it in the escos...but then transmission will be the flaw ...scrap this idea..ROFL.

 

The other flaw is you have no map to compare against or copy for a GT40 YB... so youd be fooked

 

If its any help, i'll chip in Ł25 via paypal to the fund, be interestin

 

Been researching Materpower turbos a bit...

Thatl do wont it?

Found their website too...

Let the intro play for some bangin music

 

Stu.....like you i'd use my map as the base...and add what i think would be the correct fuelling (obviously monitering det and af ratios.....i feel my ignition map is perfect if not a little dangerous...and whatever else i would need to do

So to you

Just cause your a God in tuning dont mean us little folk with a programmable ECU are stupid...ok me excluded ...we all read books to learn.

 

Why are they so cheap Steve?

Or are the prices actually what turbos should cost if it was'nt for the huge margins other manafacturers put on?

 

Steve... looks good but so does toffee ice cream, and its not

Phil,
How can your ignition map be perfect...... for a totally different turbo and engine Anyway.. good to have some banter back... im getting back into my stride so beware....

 

My ignition map will be easily modified to cope with the 5500rpm say spool up time.......at the mo i have a 4300rpm spool up time..so i got to modify 1200rpm...then from 5500rpm to 8000rpm i will put less ignition than i got now .....the engine is virtually the same comp ratio as mine so bottom end ignition will be fine imo.


Aye good to see you getting irritated by me again

 

Doug- They cheap as its made in Brazil, and think of the wages they pay in Brazil compared to USA etc where most turbos are made...

And to be honest they not INCREDIBLY cheap, but they are cheap.
You look at costs of US made turbos from the wholesalers in the USA, and then look at the costs they then sold on for in the UK (im thinking turbonetics as an example), then its a joke, talking 800quid vs over double that...

I wouldnt buy one myself until i had more proof that they good, but for a test engine like this, or generally a cheaper engine build than the one im doing, then i think its well worth the risk...

ALSO! Ive also seen in my searching, at least 2 warning NOT to buy these dead cheap T70 turbos thats been advertised on Ebay a lot lately under various names (they usually got garrett branded compressor housings), unless they MasterPower ones, as the others, as i expected, are just tidied up diesel jobs that blow to bits...

 

Stu/Karl, I will donate an S8 ecu with suitable base map if you want.

 

Good chap

 

.....aslong as it aint MY S8

 

I don't think I could lose it completely Stu, as I was going to base the new engine on the block. If you test it to it limits It could be blown to smitherines

 

Steve, the thing about std components is true. I got fancy cossie rascing pistons in my engine, but i bet the std mahles would be fine for some big power. And u can do a rod from det - ive done it... Smashed it pieces.

Need to find a turbo for a cvh - dont see the point of t34 - too old.

 

With regard to donations, could a list be put together of the bits that would be needed? I for one would love to contribute to this but dont know a great deal about building a cossie engine from scratch, mine came with one when I bought it. I have bits kicking around, as do alot of people i would think.

 

If there is interest in it, i will help in any way possible.

 

good idea for a project.

fund it by raffling it 10 quid a ticket - what kind of budget does it need? surely no more than 5 grand for parts, but then karl and stu's time would be required, as well as a dyno as mike says. 500 tickets and you've done it.

 

Id put money in to this if i had a chance of winning it (or the remains of )

 

OK, thanks for the offers of parts/cash - we will leave it up to Karl & Stu
to request how thay want to proceed - sure they are not looking for a lot of dosh, as the whole idea is based on simple/cost effective big power tuning

 

I dont think itd cost much, i mean, i dont think we need a NEW YB engine do we, just a decent condition one, or maybe all the 2nd hand bits to make one, and just new bearings n rings.

2nd hand audi wastegate, turbomaster turbo, adapted 2wd manifold, 2wd coolers welded togehter, blah blah, shouldnt cost much...

 

My Engine (41,000 miles from new), T4 Turbo, Greys, and everything you need is available for the project, as long I as get it back when it's finished. And I'll make the car available for any features you want.

How's that !!!!!

 

i have a wirerung 200 block you could use


its been stood a while so might need a re hone and the boltholes were the altinator screws in are a bit fooked but its on standard bore and free

 

Karl hasnt expresed an interest in proceeding with this project yet folks so slow down, dont forget this was started by a sheer chance comment this afternoon

I personally dont want paying a penny for my time as im interested enough in teh outcome to spend a good few hours of my spare time playing with this toy

 

Engine could be ideal Jim........lets see how Stu/Karl feel about your offer

As for turbo - I think they are planning something quite a bit bigger than a T4

 

Same question to you i guess Jim;

Ae you willing to let us kill that YB by accident at your cost?

 

Stu, If it does go ahead,

As well as an ecu, I can sort out a proper Engine Dyno session

 

i read this thread on my phone and sooooo thought it said V8 engine project... not YB lol!!!

nowwwww that woulda been interesting!!!

sounds a wicked project though - just hope that people are interested enough to have a crack!

 

FAO : STU

YES....... I TRUST U.

JIM

 

This is romance, in its purest form!

 

stretching the boundies needs more than trust

 

Jim,

What if they sub-contracted the engine building to IMA (Phil) ??

 

This was always my idea for my engine... The most bhp/torque available from a standard YB, using just injectors and Turbo, + the right ancillaries which I already have.

Jim

 

Doug : Ima....... That's what I said. I trust Stu and Karl.
