    More power please

    Lot of time on my hands - away on business and bored [img]/ubbthreads/images/graemlins/frown.gif[/img]

    What are the current upgrade options for the S3 beyond a chip?

    So far I've read about:

    MTM - too rich for my blood and not after silly power
    Jabba - not many S3s running the IHI so a little nervous about this one
    Hybrid K04 - Some people say they're great, others that it's not worth the money.

    ..keep reading that the manifold is the restriction, turbo dynamics keep threatening one that'll fit but nothing is forthcoming.

    The S3/TT have been around for a long time now, so why the lack of options?

    Old car (Fiat coupe turbo) is far rarer but the tuning options were much better.

    I'm after ~300BHP/300lbft .. has to be reliable (daily driver)

    Cheers!
    Adam

    Re: More power please

    The IHI is a reliable solution. The reason there are very few floating about is because Jabba have not yet made a downpipe for 4wd models so its all custom made by whoever fits it (AmD have done some S3's). Basically, the S3 engine is no different to any other 1.8T (Basically! the rods, pistons .etc .etc are different) so nothing to worry about there. You should expect about 330bhp adn 330lb.ft

    Re: More power please

    I was told from jabba that the manifold was really restrictive on the S3 too. There was one on the bench there and it did look as though it could benefit from a bit of machining/porting etc but i dont think that would yield much power.

    I've heard a KO4 can deliver upto ~300hp so maybe an enlarged manifold is the key? Rich will know, hint [img]/ubbthreads/images/graemlins/wink.gif[/img](enlighten me again)
    Also i've read turbos with the turbine blades clipped, what does this acheive?

    I too want to see around 300/300 but im bucked if im spending 6000.

    Re: More power please

    Have you had your car rollered monty? I was wondering how you find the REVO map and what real proven power it gives???

    I know alot of people claim 270 - 280 is unachievable just from a map because they haven't seen it on their cars but i know of an S3 which has recorded an average on three independent rollers of 281hp and all it has had done is a REVO map DV and Samco TIP, so they cant all be bull results!

    Re: More power please

    281bhp from a chip on average seem way to over optomistic. I think an average of 255bhp would be more the norm. The owner of the S3 must have had some other things done to his car to get a result like this. This would mean he's not too far of the 300bhp result Monty is after.

    Re: More power please

    Going on the rollers in Feb, very doubtful it'll get anywhere near 280BHP. I think most chips are in the 260-265region .. anyone know why the LCR lot get more from theirs? Haldex losses on the rollers or something else?

    Thats what i was thinking as most on here claim 260-ish and the REVO is a generic program. The car is an early one (v reg) from my area and the guy hasn't owned from new but hes adament thats the only mods. The car was chipped when he got it and he didn't believe the plots himself so got it re done and i've even seen the plot recording 283hp. Its actually recorded as 283cv which im lead to believe is bhp??? it also has 110k miles too!

    281bhp from just a remap... that must be a really agressive remap... must be about 1.8bar boost!

    I spoke to Craig @ Turbo Dynamics and he said that modifying the existing K04 turbo would possibly produce an extra 20-30bhp, but your main problem is the manifold... it wouldn't last long because it's so restrictive.

    Modifying the turbo cost from 395 upwards... all depending on the condition. Turnaround is 2 days.

    I think you are getting a bit confused Grant..
    Peak boost only affects peak torque.
    1.8 bar peak boost will equate to about 320-325 lb-ft...1.85 roughly 325-330 and so on...

    Peak power is dependant on air flow...the K04 can't move enough air...so the pressure at peak power is about 1.2 ish bar.

    You can map a K04 to produce 1.2 bar from peak torque to peak power...only have 230-240 lb-ft of torque and still have over 270BHP...with a flat torque 'curve'
    But you can't get a car peaking at 1.8 bar at peak torque, to hold 1.8 bar at peak power...it just can't move ebough air.

    Cranking up the boost only really adds torque low down...you need to add more ignition advance or add a bigger turbo to get more power at peak power.

    With most NOS kits, you are recommended to fit a progressive controller which will gradually and smoothly deliver your extra power rather than the "Fast and the Furious" style where you hit a button and shoot back into your seat!

    From what I remember, Caney on the TT Forum runs a 100 shot of NOS in his TT with no problems.

    Cost for a professionally installed NOS kit is about 1k.

    So is a realworld 281bhp possible with a standard KO4? and can anyone confirm what the unit CV mean?

    Interesting ... wonder if their TT manifold is anywhere near ready....could be a decent combo for those not wanting to spend silly amounts of cash.

    Makes for interesting reading this [img]/ubbthreads/images/graemlins/laugh.gif[/img]

    If I don't get my Evo 7 in a few years I will defo consider going down the big cash/big power route.

    I just need someone to take me out in theirs and show me how slow mine is compared to theirs [img]/ubbthreads/images/graemlins/laugh.gif[/img]

    Not for much longer Rich.
    I've got a brand new large port head being ported and polished at the moment with single piece valves to be fitted to it. Pauter rods and 9.0:1 tt pistons going in at the same time, along with the bigger exhaust housing on the turbo.
    I'm going to run 21psi to the limiter if the turbo will hold it, plus push the limiter up a bit if I can.

    If the turbo runs out of airflow, then it's VF22 time. [img]/ubbthreads/images/graemlins/devil.gif[/img]

    No not bored, just got the offer of the head, and it spiraled out of control to a point where I just said '***k it, I might as well go for it.'

    It'll be late feb early march before it's mechanically complete, and then I've got to run it in for a 1000 miles or so, so hopefully mid march, I can wind the boost up and see what happens.

    Re: More power please

    What would be the pitfalls of making up an adapter plate to fit a B/T onto the standard manifold? granted the manifold would eventually crack but should be cheap and easy enough to replace, what other problems could arise?

    Andy,

    You could always get a stainles tubular manifold custom made? This way you can use any turbo you want.The problem with the S3 manifold is that its too restrictive... the ports are VERY small and would require a lot of work to get it to a remotely reasonable standard and even then, its just not big enough...

    Re: More power please

    I've phoned various companies Rich about fabricating a custom s/s manifold but because it's a one off you're looking at over 1000 for the work and they also need the car for a while.
    I was wondering about the plate as I think ATP do a kit with a GT28?? and an adapter plate

    Andy,

    Explain that it will be far from one off, and try to claim a discount for development. If you have a manifold that will fit the IHI turbo or similar custom made and then reproducable, they'll sell...

    Re: More power please

    What is the better IHI turbo for the Audi?

    The IHI VF22 or the IHI VF34, and can someone explain the differences and pros and cons of each please.

    Thanks

    Basically:

    IHI VF-22

    Pro: high power output ~360+bhp
    Cons: Increased Lag

    IHI VF-34

    Pro: Very little lag for its physical size.
    Cons: lower output ~340bhp

    Jabba have a proven manifold for the IHI... The only thing needed is for a GT28RS manifold.

    Has anyone thought about buying a jabba manifold, cutting off the flange and welding on a flange for mounting a RS? Wouldnt be hard, and would mean the turbo is located in the right position laterally, youve got a damn good manifold .etc

    I've tried that angle David, the response was that I would get money back after they had sold a number of them, so shelling out for the manifold at that price and then the rest that goes with it would bring me into the IHI territory anyway, a tried and tested kit

    of all the options possibly available

    the ihi isnt a developted kit for the s3 - you would need to get custom oil/water lines and downpipe, but the manifold is there. you would also need a custom map so would need to transport the car to get this done

    apr are not going to do rhd kits, but in theory you could buy one o their kits and a jabba rhd ihi manifold and hack the manifold to fit the turbo in the apr kit - this might then just need a bit of tweaking of the mapping but the basics should be right. you might have to modify the oil and water lines and again you would need a custom downpipe

    the sportec stuff is just silly prices

    the mtm kit is well developed, off the shelf and takes 2 days to fit - thats why i eventually went this route- all the other companies required too much bodging/hacking with little support if it all went horribly wrong.

    Re: More power please

    I've heard that the 28RS won't fit on jabbas manifold on a golf platform, as it fouls the bulkhead.
    JBS are trying to develop there own manifold to fit a 28RS, using some bits from ATP with their own manifold.

    But why bother. IHI kit is anything but fully developed, but it can be made to work relatively easily and in a reasonable time.

    It won't make totaly silly power, but the VF34 can be made to produce >350hp with some other tweaks, and retain sensible drivability, with low boost threshold etc.

    You cannot use more power than this on british roads for extended periods and either stay alive, or keep your liscence.

    You are also looking at silly money whichever route you take, and you could pick up an early 996 porker by the time you've finished.

    If I ever stop chucking cash at mine, it'll have cost in excess of 30K if you include buying the car new, and i've done everything cheap, with lots of freebies and favours along the way.

    My advice to anyone is chip your s3 or a3 and enjoy the 50hp gain for 500. To get the next 50hp will cost you 5k, and the next another 5K

    If you want more, buy a car that was designed for it in the first place. porker, evo etc.

    But I did it anyway, and I'd do it again.
