Project Widebody s4 600/800 (ex stumpys)

Ok so picked car up a while ago here is the car as it stands now
Car drives amazing its like it on rails
guymcc

Wow, ghost like!

Has it a camoflage wrap now?

I had no idea that ACME Disappearing-Reappearing ink was available as an automotive finish topcoat.

I helped Jimbo remove it, and fit this one

Carbon bonnet no good to me as it would fill with water so
Looking at a respray before I put it all back together

With carpet dash and a heater

Why the hell you would remove the blower Id never know

Paint choices

Stay the same gtr grey and add little bits of colour and spend money on other shiny bits (I do like bright colour's)

Imola yellow
Triumph diablo red
Porsche rs flat orange

Was going with lambo orange but they sprayer said if it scratches matching in will be impossible

Depends on your use of the car and budget I guess.

See Jimbo off loaded the wheels as well in the deal
rs6 hib

Yes I hate the old wheels that where on it didn't suit the car at all
Going for rota grids

My wheels would look so good on this...

Looks good, love the colour.

I'd stick with this colour and paint the grill surround and window trims etc gloss black. And put clear headlights back in

ok so been a while since i posted on this thread
got my engine spec below

just in 2 minds as to weather to lower compression ratio with a gasket and what turbo to go for at the moment the car does not feel like it has much torque compared with my old ko4 set up may be its not a good map

does any one have experience going from a k04 to tte 600 or 780 and how it felt in comparison pick up etc

any advice would be gratefully received
rs6 hib

I'm looking at tte600 or 780s at the moment I have rs6 oem on the car any one with similar setup could tell me what spool up is like etc as I don't want car really laggy
What sort of realistic power am I looking at with 99oct fuel with these turbos

Is worth lowering compression with gasket can any tuners advise  


The engine is assembled with:
- Oversized pistons Mahle Motorsport 81.5, stock stroke, 9.0:1 bought and installed brand new with piston rings and piston bolts
- Engine block bored and honed
- forged rods Maxspeedingrods
- new main, rod and thrust bearings from Mahle and Kolbenschmidt
- brand new 2.5TDI oil pump(upgrade for 2.7T, same as the TTD one) with new wheel, chain and tensioner all brand new and OE from Audi
- head bolts Elring
- head gasket Elring
2.8 Inlet cams
- head from 2.4 30V BDV engine fully rebuild(crack and leak free) with new valve seals and guides, new hydraulic lifter from INA, new sport intake and exhaust valves from Rosten Performance, new uprated valve springs from FCP Performance, new titanuim retainers from Rosten performance, new cam chain tensioner from Vaico, new cam chains from Audi and all new gaskets and seals including the valve cover gaskets
- measured and polished crankshaft
- Silly Rabit Motorsport bearing girdle with ARP main studs
- new oil level sensor in the oil pan
- every gasket, seal and O-ring has been changed
- new one way oil valves in the V under the crankcase breather, new crankcase breather gasket
- brand new spark plugs
- brand new lambdas

- full serives including new tensioners for the timing and service belts from INA, brand new Ina timing belt and service belt, new Thermostat, new water pump, new pulleys....
- brand new MAF, not refurbished bought 3-4 months ago
- new coolant temperature sensors
- Apikol mount at the front of the engine used for 10-12 monthts
- fully revised engine starter and alternator
new Fluidampr pulley
Full 63mm the tuner inlet pipes and y s

ive driven that car dude and I seem to remember that its an easy map on those turbos.

You'll have to check back to when it was stumpys and have a read.

K
rs6 hib

Yeah I think it is your right read the whole thread before I got the car

No point me remapping it as I have the new engine to go in

Its a job to know which turbos to go for as I don't want to pull the engine out again  and weather to lower compression

If any one is down south with tte600 or 780 that will give me a ride in would be very grateful
armageddon

After seeing the other topic logs, go for the tte780
rs6 hib

Yeah I'm thinking that does anyone have a graph comparison between 600 and 780
S4Player

speak to si from TTE. He'll help you out, my first build was on a turbo of similar spec to 600's and it was stupidly fast. Made my supercharged b7 feel like it was going backwards

What was the spec of the motor and the turbos dude?

Thinking about making some 600 spec copies for mine.

You got a graph?
S4Player

Overbore to 2.8, wossner rods and pistons, rebuilt rs4 heads with a slight port with loba cams and lo600's from loba if memory serves me right or it may have been 700's I'd need to double check. Made 680ps and around 900nms, I'm sure it's in a build thread on here I'll try look. Was stupidly fast
rs6 hib

The more I think about it the more im swaying towards the tte780s  

Just need to work out if I need to lower the compression or if I can leave it as is
qaiserrs6

Im running the TTE780's and have lowered the compression on mine, if your ever up north i can take you out in it
rs6 hib

What compression are you running and what sort of power is that giving you

mine is 9.0:1 how much do the gaskets lower it by and where is it best to buy them from
jimbo

keith ,this is the car I was talking to you about yesterday.
its running 8.0-1 cr makes just shy of 700 ps.
thick gaskets drop the compression by an extra 0.7 -1 cr over std gaskets.
they are made by buying 4 gaskets and making 2 out of them, its not rocket science but you don't just put 2 gaskets between the head and the block, each gasket has 4 layers so you make a 6 layer gasket out of 8 layers in total.

You missing it by any chance C?

Yup. Considered buying it back from the guy who bought it off me, and Jimbo, but I'd want to spend too much on it, so didn't make any sense.

Another WB though...

tte or rs6 turbos

so i emailed simon from tte and he sent me these graphs which is same engine spec as mine with the same compression as mine still in two minds which to go for as cost of tte780 will be about 3k more

ben at the turbo unit says stage 1 rs6 for the best response and spool up and about 600bhp  

does any one have graphs comparing the different stages of rs6 hybrids on the same set up engine

what does this mean?
rs6 hib

flbs of torque

oem rs6 vs tte780s
Kent

no this... 'stage 1 rs6'

that doesn't really mean anything.
rs6 hib

different billet wheel hybrid will need to speak to ben re exact info

On wheel to mention as well

It is at 20% tranny loss apx

850nm for oem RS6 - flywheel
1000nm for TTE780 - flywheel


Go 780s or you will pull your engine again.
Oem RS6 turbo is fairly fast spooling and you clearly see there is no substantional difference to TTE780.
Any hybrid stage RS6 are slower than oem.

I will also ad that RS6 turbo log was taken at much higher amb pressure day. If TTEs log was taken same day it would spool even faster. IAT temps were similar.

I can post a log on it later today.

This is the log from the same run on both turbos. It shows that intake temps was almost the same. RS6 started at 18 degC and TTE780 at 14.5 degC. Outside conditions was considerably favored to RS6 turbos as this run was done according the log in much lower amb pressure day. 1000mbar day for TTE780 vs 1030mbar for RS6. This means if TTE log had been done at the same day with much higher amb pressure -. it would actually pick up in spool even better.

Turbos

This looks good the only thing is

Ttes seem to come into there own at nearly 6000rpm well for a Rd car you are well into 3 figures by then that means your nicked

so been thinking long and hard over the last few days and with that in mind and the extra 3 grand cost for an extra 100bhp at the top of the rev range I'm not sure this is usable on British roads
May do the odd track day and Europe trip but I'm not sure it warrants the extra 3000 in cost

So I'm really swaying to rs6 hybrids
coullstar

Sensible choice, I think a lot of people get into the more power focus when doing this sort of thing, I know I would but it comes down to what you use the car for.
rs6 hib

Yeah I think you can just chase numbers if you are not careful

Your write in what your saying apart from you've not quite got it right about the turbos.

The TTE780s are so good because for such top end grunt they still spool really well.

Its the RS6 hybrids that you need to watch as although you will get some great top end power you will lose the early spool.

Its not all about the top end figure but about the volume of power under your graph.
rs6 hib

Yes but all the graphs I have seen are pretty much the same until you get to 5 to 6000 rpm I understand they are great turbos  I'm just trying to
Justify the extra 3 grand cost for the the 100bhp gain at the top end and realistically how often I'm going to use that

Don't get me wrong I'm swaying at the moment and have a lot to buy it just means the car will be off the road longer if I go tte780s

The turbo unit have developed a billet wheel that does not surge on inlet with seven or 11 blades they can be clipped if needed
Kent

i can see why you'd say that as they do look similar. They are not tho. Take any two graphs of 780 and the rs6 hybrids you can find and compare any data point from the mid range and you'lll see a big difference.

Here is a comparison of two cars same fuel...

2.5k - 300nm - 330nm
3k - 390nm - 450nm
3.5k - 500nm - 650nm
4k - 700nm - 900nm

RS6 hybrids behave in exactly the way your mentioning - "100bhp gain at the top end and realistically how often I'm going to use that"

If thats your arguement you dont want RS6 hybrids.

As Kent said, i think you are not understanding torque and meaning power under the curve well.
I can only tell you this. Turbos you are comaparing are not to be comapred in the first place. Good luck.
