Is this loud?

[bassed]

I didn't get no stinking fan

[A4Rob]

My speakers were turned down, so no it was not loud. haha

[AudiSportB5S4]

haha yeah you can hear it gets loud for sure.... what did you put down on that shitty day?! i was there it was stupid outside. i cant believe no fan!!! HAH. why did you payyy for that

[biketsai]

thats the sound of a monster

[audiness]

Big turbo? sounded cool

[1fstavant]

yea bassed what did u put down....and i bitched and moand for that fan they werent gona run one for me either but i layed my pimp hand down

[bassed]

The W8 Passat after me put down lower numbers than stock.

Kinda big some would say.

[audiness]

wow.. look at the power curve

[bassed]

This one is better representative. You can also see how much boost I was running, which for this turbo is nothing.

Crank 'er up! The same turbo on an SRT4 put down some wicked #'s in the 25-30psi range.

Why do all your videos make your car seem so smooth? Keeping the boost down a bit probably helps too.

Good video, Unitronic tuned car, nice big Uni poster. Now if it were only 60degrees outside.

It seems smooth because it really is smooth
Even in turns The tune is very linear and smooth, just running a tad rich like a whole point as you can see in most of the videos. I would prefer to see like 12:1 not 11:1. I think there is a lot more to be had even at 18-20psi. I have been driving at 25psi all the time. It's just the camera can't take it, it always shuts off, so grabbing a Cannon DV20 is on my to do list so I don't have hard drive issues killing good videos.

Definitely would enjoy the videos a lot more, if they were longer.

How's it feel on the butt dyno 18psi vs 25?

You're AFR doesn't look that far off. Don't boosted cars tend to make the best power around 11.5:1? How much timing are you pulling?

19* and it feels much stronger at 25psi with W/M. A bit leaner will be faster and burn more efficiently

A S258 which is closer to what his hybrid is capable of did well over 500whp on a stock block evo running race gas.

GT30R power with spool slightly better than a 3071r.

Personally, I wouldnt have run without a fan... Thats completely BS that they did that to you..

Its not that loud, it does sound good though! My borla w/ test pipe and 1 muffler removed is louder than that.. Too loud infact, I put the first muffler back in..

[andyrew]

You dont dyno it personally, there is another person driving the car (employee of the dyno shop)

You just sit back, watch, and think of all the possible things that could go wrong...

He wasn't referring to the exhaust. The compressor on those turbos howl like a possessed banshee.

I am getting frustrated with not tapping the potential if this snail, I saw a few other setups running the S256 and S258. Thanks for the swift kick in the balls Jim I need to adress this quickly.

OK guys I just got a chance to sit down and look at the logs. I will keep updating things when i have more time to look at them. First thing i looked at was the Airflow. His 3076 same boost was low to mid 2000s hz.
Tonight with the CBRD/Blouch hybrid we saw 3079hz constantly. This turbo just flat out moves some air. I really cant put it into words how this turbo hits. Its really is crazy. This is also with a good cam gsc s1 but ith a tad bigger cams forget about it. This is a great street turbo. No significant spool loss 100-200 rpm and crazy top end compared to the 30r.

The turbo rocks guys. What the 30r lacked up top this new set up made up the difference and in my opinion for my driving style this is the perfect set upi for the street. I love how the power comes in smoothly and then its like wham lights out lol. It was a long day but the end result was very rewarding and the CBRD crew is top notch guys. Charlie thank you as always for making me smile with your tunes. I had a great time with you guys yesterday and I appreciate all the hard work that went into it. Chad gets a A+ in math

[317ssayzarc]

you need a bigger AR Ian

[AudiA4_20T]

you need more boost Ian... we need to have a custom tuning/possibly standalone option for us thats plug and play. That Evo you posted runs AEM EMS

I know you have your Uni tune but its annoying to have to go there every time u want to change something

[bassed]

Nah the .55 should he ideal for track and street. I'm not to off with 328/272 at 18psi. It's a matter of more boost and hoping on the Dyno again. The tune needs to lean out as I've mentioned. SDS or lugtronic are last resorts.

[onemoremile]

They run all sorts of different engine management, headwork, cams, etc.. I just wanted to show what the turbo is capable of. On a fully pimped out setup the S256 has hit 502whp and made a relatively easy 480whp. S258 is 30-60whp higher and a few hundred rpms behind.

[Don Supreme]

As I tell Clint all the time, forget the turbo... getting a turbo is easy.. Evos and Sti can hit 500 whp with just about any decent turbo 50 trim, gt30r, etc, etc.

Yet we struggle to hit 400 whp with even bigger turbos. We are missing something.....

I am trying to narrow this missing element down.. Right now I am thinking its either

A. Air flow (from the WIDE range of cam selection those motors have, especially 4g63, etc, etc)
B. Custom tunes

Hopefully I will know the answer soon enough.

The answer is in the head and the overall relationship between backpressure and intake manifold pressure. IM psi - backpressure psi = working psi. Lowering one is better than raising the other. You get the same result but overall efficiency is improved.

We only need one or two good cam profiles to be available. The problem is the lack of performance data available. Sport Compact Car just ran a series testing more than a dozen Evolution cams on a 35r equipped car and we need to see some results like that. Maybe we can petition Bob Q or 034 to work up some real data that they could use to move a lot of cams. This "you'll have to take our word for it" crap is pathetic.

[Don Supreme]

"you'll have to take our word for it" crap is pathetic.

I am sick of that shit too and then i saw another tuner on here (who shall remain NAME LESS) making a childish comment, something along the lines of "If I build it right everyone else would copy me" ---- What the hell is that?

Anyway, Bob was supposed to have a BIG BIG cam test last year June/July, but it never happened....

I guess he is selling enough not to justify the R&D that I think we deserve..

None the less I took the plunge and ordered a set of cams (From Bob Q - Great support) that I have never even seen a dyno for.. I sick of being a guinea pig... I pray that it works well for my setup.

[onemoremile]

That research data would help him too.

A nice site with plenty of dyno plots is like the menu at Denny's. People point at the one they want and hand over money.

Those that worry about others stealing their ideas need some confidence. There is always a lame copout to stand behind.

Honestly, I completely agree with you. Its seriously a HUGE lack of data, and also tuning, that is HUGE

It would be cool to actually do the dyno, but yeah, the data must be a great thing to have for tuning.

I have a feeling it's IM pressure for me that needs to lower. I have very little back-pressure as it is. I don't have a built head, just a AEB with 14k on it. The difference for turbo's this size on the 1.8T could come down to TB and TB inlet diam.

I'm sick of being a ginea pig as well, this setup is so out of the Audi [ ] that it doesn't matter anymore. I've made good ground and have proven another setup basically at this point. Granted I would like to hope on the DYNO again and see what 26psi with w/m does.

That would be wonderful!

The only data I've seen are back-to-back dyno runs with stock cams and Cat Cams 3651s. The 3651 run was lower octane and boost and it still made more power (10-14whp? I can't remember). With higher octane and more boost I'm under the assumption it'll make even more power over the stock cams. Well.... that is why I put a set of 3651s in my car. We'll see once I get a new [custom] tune.
