30v Tuning

Posted: Tue Mar 25, 2008 11:38 pm

I have already set in mind the exhaust and air filter, though still wondering if it's worth putting in a bolt on cone instead of a performance replacement (The V6 sounds great but I don't want it too noisy). I had an ecotek valve on the Coupe and I noticed a big difference in the initial throttle response as well as fuel economy, so for what it's worth I'll have one of those (with the muffler). But I have noticed performance ignition systems and distributor kits about and wondered if an upgrade (including leads and plugs) would be worth doing?

On another note, has anyone ever heard of splitfire's ceramic power boost?? "advanced engine protector" Question

Sounds a gimmick to me but claiming better cold start, increased engine power and reduced fuel consumption Question

I've got a ram air filter on order for Rebel Ship, S/S exhaust went on last week and instantly made a difference. Istoo points out and I've also come across web sites stating that you can increase 30v bhp from 194 to 224bhp with filer and exhaust alone....not bad Cool

I'm going to beon the prowl for a supercharger kit over the next few months which should upower to 280bhp but with much better responce etc wonder if anyone has managed 300bhp from this approach?

The S/S exhaust I have been quoted for includes a high flow sports CAT, So I'm hoping with the filter i should break 205 but hoping to bust 210. I looked at the Ram Air, Super ram I think (about sixty or seventy quid) and had a thought Idea

. What I should do is get it on a RR now whilst it bog std and then report back after the filter, S/S, Leads & Plugs and ecotek are in then report back on the difference.

You going to cost me alot of money I know you will Laughing

. I have thought about supercharging, but even as it is, the lowest mpg i have reached is 8.2 and I don't fancy getting it any lower Laughing

.

Nouwt wrong with the mid to high end, but unless you boot it off the line, I have noticed that stock is tiny bit lazy on the up. Get it around 3500 or maybe a bit less in third, and she pulls a treat. I was following a Bayern 2.?? along the carriageway earlier and we came to a kind of roundabout (but not quite) and i think he was a little perturbed that i caught up with him on the corner, so he decided to floor it off the bend to try and beat me, he had a car in his lane about 150 Meters ahead. I Dropped to third and flew past him before he even knew what he was up against Twisted Evil

Then I get some stupid *censored* in a so called pot noodled Corsa GSI thingy wanting to race me through the country lanes. Either he couldn't see the badge or thought he knew the lanes better than I did (been driving them for years Twisted Evil

) got to the first corner and never saw him after that Laughing

I noticed your posts earlier on these young idiots wanting to test their little toys on real motors, and it really is surprising. Dont mind going against Audi's or Bayerns, more fun, but come on a little car with a few tin cans stuck to the engine?????? Never understood it. I think your far better off leaving RS debadged. I might go down a similar route, just seems a shame to hide him!!!

Best of both worlds guys... Coupe + 2.8 30v + supercharger Very Happy

supercharger thread

second gear at 6k revs is like a jet at take off speed..awesome stuff Twisted Evil

I noticed your thread a while ago. Looks like an amazing amount of work Shocked

but I'm more than sure it was worth it Twisted Evil

I have mine booked in for a RR next thursday. Going to get a power run with it totally std just to get a base point. If I can afford it, I'll put it through again once super ram and S/S are installed and then again after ecoteck and ignition upgrade otherwise i'll wait till its all on and do it.

Docurely corrected a misunderstanding today when I made an enquiry for a new PES kit for RebelShip.....so PES is back on Cool

New prices are stupid (£3.5k to import plus taxes) andI only have £1.5k so will have to hunt high and low for a second hand one.

Fast - I've been told that a real amateur (mwa) could fix the PES kit to the A4 as there's no modding needed.what do you say?

Cheers

Just been looking for a thread I read a little while ago but can't find it now.

It was something about when installing Ramair and the like that an Oil catch can/tray will be needed. Have I got this right or am I off on one my own little walks here??? Laughing

Posted: Thu Mar 27, 2008 8:15 am

There is a copy of the PES G2 instruction manual on the net or search www.scaudi.com. There are no modifications req'd other than bending the power steering pump line, everything just bolts into place. You need a basic understanding of engine components but it's a fairly lengthy but basic installation.

Excellent, thank you Fast, thats sorts that one out. I have been speaking to Proven Products about induction Kits, and apparently Ramair have temporarily stopped supplying the Supa Ram and they don't know if or when it will resume. They are offering me a K&N 57i instead??

Thanks Andy. I ordered the K&N today, will be with me Monday. Exactly 100 inc delivery and membership disc Cool

Going to get my EBC's from them too just need to confirm the type of pads that are on the car. Apparently they randomly fitted three different types??????
Ordered an ecotek CB-26 Pipercross filter for the valve. I bought a valve to go on the missus' old renault but never did get round to it, so thats mine now Laughing

It's also booked in for S/S and they will also put the twin hi-flo CATS on too. only 220 each for the cats and about 260 for the remainder of the system. Good value IMHO and the company have been mentioned on here a few times. Got to travel to the West Midlands though.
Tmw, I'll be ordering the plugs & leads. Looked at performance coils and dizzies but for the price, are they really worth it??
Got some wheels in the pipes courtesy of S4_SAT (SAT, I will be in Walsall on Friday 11th April??).

After all this, I'm hoping that the full inspection booked for Mon, doesn't throw a spanner Evil or Very Mad

It's not going in till eleven on that morning and I reckon it will take several hours so who knows, May get a chance to see ya??? I'll be down Pleck Rd, MIJ.

Posted: Fri Mar 28, 2008 5:31 pm

Splitfire plugs & leads now on the way. Proven couldn't give me a discount on these as they are one of the few items they stock that is discounted anyway, they did knock a bit of carriage though. They are supplying sets of six so I didn't have to buy a set of four and then two seperate ones Very Happy

Leads were a bit expensive though, splitfire were the only ones they found for my engine.

Posted: Fri Mar 28, 2008 6:16 pm

splitfire did have a good reputation back in the day; not heard much from them lately.

With regards location, Walsall isn't far from me or work, but too far for "lunch"- I live in Tamworth (about 15 miles) but I'll be at work (near Brum airport) Sad

Posted: Fri Mar 28, 2008 6:49 pm

I used them on the coupe and again noticed a slight improvement. They had the NGK's but he put me on to the splits. Tempted by the triple platinums but with no noticable difference between them, but with quite a difference in the price, I went for the cheaper ones Laughing

Posted: Fri Mar 28, 2008 6:52 pm

let us know how they perform; maybe worth changing your avatar Wink

Erm..... yeah......er need to downsize one of my gallery photos though and not had the chance Laughing

Just got back from picking the car up from the rolling road. I was surprised a little by the figures but looking back, I shouldn't have been.

Parkers guide quotes 193Bhp with 280Nm torque, so I figured if i were to get 185, it would show the fact that it is a nine year old car. WRONG. it came out with MAX 210.2 at the crank, torque is reading 170fFTLb and lambda came back at 0.9????? (Dont know this one Embarassed

), however, this is at 7000rpm. At 5500 it comes back with 190bhp and 183fFTLb torque. Confused

Lost about 40Nm. anyone know how to get torque gains or any ideas how to replace them and gain??? Carbon flywheels???

I can only put it down to the fact the car has 75k and has loosened up a bit. Now to get the parts fitted and we shall see.............

Incidently, open air induction filters like K57i aren't all that. They tend to draw more hot air in than cold air, even when ducted to grill. The way to go is either install a non-oiled element in the box or get an enclosed cone ducted. I might try putting in a cowling around the cone and duct in with 4" pipe.

Posted: Thu Apr 03, 2008 9:10 pm

Some good figures there Smile

BTW the V6 engine makes peak torque around 3.5k revs and drops back gradually. Power will carry on climbing. Must of been scary hearing your engine rev all the way to 7000rpm Shocked

I don't think I've even reved it that far in mine! - used to having the old 12v Razz

If you want more torque then cramming more air into the engine is the only way, without forced induction it's smoothing the airflow into the cylinders as much as possible and removing as many obstructions as possible from the air filter to the combustion chamber. The 30v engine forum on Audiworld.com is a good start for reading information, even better is the 12v engine forum, much of which applies to the 30v engine!

Your lambda at 0.9 is on the right side of 1.0. 1.0 being the ideal air-fuel ratio of 14.7:1 which you will see at slightly loaded cruising conditions and idle. Open throttle conditions require an ideal ratio of 12.5:1 - 13.0:1 to make maximum power in a naturally aspirated engine. 0.9 is spot on at 13.2:1. Smile

Looks like a healthy engine to me!
On a dyno they can't really replicate the effects of ram-air on your intake and even with the fan blowing the engine will run hotter than if it was on the road so on a nice cold winter's morning running at 70mph there would possibly be more power than the dyno states. Quoting engine dyno figures is a grey area as transmission losses will be different for each make of car but the A4 quattro 2.8 generally loses about 50hp through the transmission (manual).

Posted: Thu Apr 03, 2008 9:45 pm

Thanks fast, this has really helped me put it all into perspective (Newbie RRer Smile

and a bit of an engine numbty Sad

) I did wonder about the differences on the ram air between sitting still and cruising down the road. I was originally looking at the 12v on the cabby and was pointed to that blokes thread on port polish etc but I would of thought the 30v, being a newer lump, they would have sorted the mismatched gaskets and smoothened out the ports a bit better? As for the torque, peaks at about 190fFTLb at 2800, drops a minutest amount and goes back and starts dropping again at about 3500. Rises a bit again between 4700 & 5700. only about 20Nm down on the book. Handy knowing this actually, means I can drive my car to it's optimum points although I would really like some more low down punch like you see with the T's. Guess i might be going down the PES route afterall Twisted Evil

I did cringe when they took it way up there, but boy, even though it's still std, the 30v sounded nice all the way through the revs. Now I cant wait for my S/S system now Twisted Evil

Thanks for the vote of confidence too, getting the figures is one thing but understanding if it's good or bad is something else. I know the car drives well, gets up and goes as well as it stops, but far from racing it at santapod, you can never really tell.

cheers Cool

interesting!
Think you can post a pic' of the plot?
What fuel were you using?
(seems i always ask that!)
What r/r did you use? How much, £50?

Not sure what i would / will do, would like to be satisfied with oe performance really.
Like to get 30v benchmarked, 12v needs doing again with decent fuel. (My plot is on s2forum somewhere)
My 30v sounds like a sewing machine compared to the cq,
Which troublingly i like and dislike in equal amounts!
Also exhaust seems in good condition. So difficult to consider replacing. Though gains are impressive! Like to see how much bottom end improves.
So looking forward to getting cq back. Soon after serious decisions to be made.
Will have to doe even more reading on audiworld.
Regards
Phil

Fuel - 98Ron (BP Ultimate) was a full tank too but dont know if that would make any difference (weight etc).

The company is Sussex Performance Centre in Horsham and it cost 106 inc VAT and they are putting their prices up soon Sad

seemed to know what they were talking about but I agree with Fast28 about the Air induction Razz

Posted: Fri Apr 04, 2008 11:56 pm

Rebel ship hits 7000 revs daily Laughing

.......mostly in second and third gears

No audi V6 sounds like the 5 cylinder (regulations stopped that) but a sporty exhaust helps Cool

After Spending 5 hours at MIJ (they also replaced my O/S tie rod end and four wheel aligned it) I now have a car that runs true and straight without any vibs and a sexy exhaust. Sounds really nice, A burble but without being stupidly loud. Ok what they installed: Two flexi's from the downpipes to two Hi-flow Sports Cats (looked a lot smaller than the orig's) then T304 Stainless back through two very small silencers to a set of twin 3" tails. Totalled a net of about £800. Worked out a bit more than the original quote, but that was because I hadn't thought about the flexi's. We looked at them on friday while the car was up on ramps, didn't seem to bad, but to me it was pointless putting in a long life system only to leave a weak point that wouldn't cost very much at this stage to replace, but would cost loads later on?

One of the guy's down there drives an S4 and another guy, an S3. The guy with the S3 is apparently an Audi nut. He asked if I was doing a remap, so I said it probably wouldn't be worth doing being NA engine, but he reckons that after all this work it would be worth doing a remap, something about the engine not running as hot??? probably gain about 20-25 horses. All the people at MIJ were friendly, and the Mech's certainly know their stuff.

I think in the future, if anyone asks me where they should go for a system, they will be the ones i mention Very Happy
