I'm not taking about thermal plates..Making a quick connect killer chiller set up..no cutting of ac lines..It will simply connect where you fill ac via a 3way quick connect!!

Interesting, sure enough that would keep you pretty damn cold... When are you going to put a build thread up?

[s4matty]

Once it's finished..Maybe 2-3 weeks.
Have to clean up the mess on my car from all the little projects lol
I also have a 80mm BMW throttle body pretty much figured out!

Not too interested in the killer chiller for my setup but, I feel like a larger throttle body is likely the next step.

How much did you have to modify the BMW TB to get it to fit? (Do a DIY? )

and the output is slightly different. You can get by with a driver box but ideally you want to open up the stock one to 74mm or so.

Dang I was hoping maybe you guys had found something that miraculously just worked.

VDO throttle bodies are notoriously bulky and are unserviceable. BTDT
IMHO a Bosch unit would be better but again you need a driver box.

You could throw a solenoid on there for on-demand cooling without the need to hook and unhook it and be able to run a/c separately. I love the idea of the quick connect. Never occurred to me!

Driver box? Any experience doing the 74mm boring of this specific tb?

Yup I have a solenoid in there already.The quick connect is just because I do not want to hack into my ac lines.

According to the charts, like 300-350RPMs on the blower more at 7k if you do it. How much that'll get you compared to the labor to change out the pulley is unknown and a call you'd have to make.

I just paid $500 for the JHM pulley so I don't want to swap that one out. I would do the labor myself so it was just cost me the price of the pulley.

I guess what I'm getting at is what, approximately, would that yield as an increase in boost (350rpms more from the blower)? If this would gain 5-10hp, it's not worth it to me.

[Ze_Nardo6]

I disagree
The crank pulley swap is actually faster than the supercharger pulley swap.
Once the vehicle is in partial service mode (i.e. front clip slid forward 3") you can swap the crankshaft pulley in under 10 minutes. It takes longer to warm up the betty crocker oven....
The trick is noting where the offset hole is. On the OEM crankshaft pulley there are 2 dimples on either side of the offset hole. What good practice would be is to install an exhaust manifold stud or any M8 x 1.25 stud into the offset hole , install the aftermarket crankshaft pulley using the other (7) M8 bolts and then removing the stud to install the final 8th bolt.


They will evolve now that tuners are more comfortable with not having a crankshaft pulley fail.

I disagree with this. I've swapped both and the crank pulley is more laborious. Having to guess the alignment of the bolts for the crank pulley is easier said than done.

EDIT: saw your method of aligning the bolts. That would put them on equal terms IMO

[Wizard-of-OD]

I've swapped both and the crank pulley is more laborious.

(8) M8 triple square bolts vs a puller + betty crocker oven + welding mits + + + ?
To each there own. I did over 20 supercharger pulley swaps and the crankshaft (to me) was easier and took less time to do.

I was trying to convince myself of that since I just did the work lol damnit..

May have to go bigger crank pulley..

[Loe]

Are you waiting till it's cool down there to put it on or just going for it now? 194 KI with the giac pulley right?

PM sent. Im undecided at the moment what to do but I still have my 179mm on; not like records will be made in mid 90's weather in FL

Had a misfire issue two days ago... I decided to try the 104 map and CW on 4-1 setting (also started experimenting with a new e85/100 octane mix). Every time I'd go WOT above 4k, all cylinders but CYL1 would shut down...

Was annoying dealing with that because it could've been a number of things (my colder plugs, the fuel mix, the CW 4-1 setting) but I determined I can't run an e37 mix on my car... Switched back to straight 100 octane, 100 apr map and CW 3-1. Car is honestly very very fast with these specs and running well. I'm going to run this setup for a while for the sake of my stock tcu which is adapting to the power quite well. 1-2 shift slips a little and the 2-3 ever so slightly when launching from a dig (no LC just mash and go)... From a 2nd gear roll, shifting at 7k, it's absolutely fantastic.

CW 3-1 seems to work well with the APR 100 map. I am hesitant to bump it back to 4-1 until the dsg is tuned.

Just wanted to share some of my testing with everyone. Going out later today to make two 0-120 passes. If anyone would like to see logs of those just let me know!

Here's a quick 0-60 run to hear the shifting

Check #1 cylinder plug
This happened 3x to me and every time the white porcelain on the side of the plug was cracked..IDN why.
Changed the plugs and was good to go

Checked plugs and all are good. It was the e37 mix that my car did not like. Runs like a champ on 100 octane gas

Made a couple test passes. Gotta love breaking traction off idle in an AWD car 78F, pss tires at 39F/38R

Looks fast! Can't believe your car isn't liking a 37.7% mixture though! Hope you can find the right mix!

[waxxonMTL]

3.4 with no tcu tune and a real dedicated tune.. i bet you would see 3.3 or maybe 3.2ish with appropriate ecu tune/dsg tune. but really that got me wondering hwo accurate are those p3 gauges.. i have a hard time believing those times.. seems too quick for a s4 compared to other supercar on the market.

Yea the p3 isn't all that accurate but I've used a vbox too and they line up surprisingly close as long as there is no wheel spin

AMAX mode would be great to have! If only!

What issues are you having with an E37-E38 mix? Yeah, on a race file, it's very very easy to break traction simply by just stomping on the gas even with the mild JHM 179mm crank pulley. I'm hoping the 194mm crank won't give me any trouble

Looks like me, you, and Matty run the same tires; I actually find the OEM Dunlop Sport Maxx GT's provided better traction during acceleration. Once my PSS's are at their replacement point, I'm going to find more dedicated extreme performance category tires or go back to the Dunlop's. Don't get me wrong, the PSS's are an excellent tire in all other aspect's, but once we get to these TQ level's, even Quattro isn't going to help with traction issues.

[Loe]

Used an endoscopic camera...please excuse the quality





Bottom line, I'm convinced that 6 ribs will not require grinding.

Is the top pic a 7 rib and the bottom pic a 6 rib?

I'm going stage 2 this coming week. I currently have the cw pro. I was thinking of selling it, but it seems like people are stacking the cw and tune. Are there any downsides to this? Btw I'm not getting the tcu upgrade. My cw is about 6 months old...does it need a specific map of sorts to run with the apr stage 2? Thanks guys.

Well at first I didn't think the misfire was fuel related. I made the mix and allowed it to run through the tank a good 80 miles. I also decided to try the 4-1 setting at the time of fillup.. Then whenever I'd go WOT above 4k all cylinders but 1 would misfire. I thought there would be fuel pressure related codes from running too much E so suspected it was either the 4-1 setting or the plugs. Still had the issue even on 3-1 setting and the plugs all looked good. Let the tank run down and then filled up with a half tank of 100. Drove at least 50 miles to get the 100 in the fuel lines and the first WOT pull was amazing (this was my first clean pull on the race file and CW 3-1). That made me think it was the mix that was causing the issue

I did quite like my dunlops as well but I think they were much heavier than the PSS are. I'm also considering something stickier after these wear. Maybe a sport cup tire or one of the competition tires

It is really amazing the level of performance we are getting out of these cars now.

Just a question if using 6 rib does not need to grind?

any slippages occur at 7k rpm?

i've had no slippage, my car only revs to 6800 rpm. 6-rib appears to not need any grinding based on my B8.5 install...still awaiting confirmation from a fresh b8.5 install. I was the first documented b8.5 install AFAIK and I did the grinding based on the 7-rib belt I received. It began slipping and I switched to a 6-rib belt that has given me no problems over the last 3 weeks...the original 7-rib began squealing within a week. After installing the 6-rib belt, I noted that the clearance appears to be adequate to forgo grinding.
