My audi CQ 3B S2 build

[chaloux]

Meh I never had surge. Both gtx with 4"antisurge and 3" compressor covers. But exhaust restriction is there so high egt and thus bambam det. NO THANKS!

First of all, I prefer to quote lowest reading dyno numbers. People swing from the dynojet nut so much that I get all kinds of shit when I do tunes on my dyno with people expecting 30% inflated numbers. it gets tiring having that conversation.

Second, 91 octane is swill when it comes to fuel selection.

Will you do better than 315whp on straight 91 pump with no det? Yes, almost certainly. I just prefer to set you up for worst possible numbers so you are happy when the final result is done, rather than the other way around!

Marc, I can see your point for sure, its better to err on the side of caution so I know what your saying, also your running a business and reputation is a large part of it so I can see why you take the approach you do. As we discussed the Meth is the best option for lower EGT so I have already looked into a Aqua Mist system to install. Your counsel has definitely not fallen on deaf ears.

I just wasn't expecting for another $1000 gone so it was a gut check for sure but its all for the best in the end. I don't want to blow up my new motor so I will take your advice and install the Meth. I want reliability and performance to parallel each other that's why I have spent so much money and time building the car before I purchased any performance parts. Usually people tend to become impatient and go straight for the go fast parts. Any way enough said, just have to scrape up another 1k for the meth.

cheers Mate

Ok finally back from fighting fires all summer. Gone almost two months straight. I got a little time to open up all my boxes of ordered parts. Got to get the house ready for winter so I haven't had any time to work on the car. I do believe I have everything except the injectors for the car which I am still waiting on Hank for those.

Got the 034 Motorsports fuel pump bracket for the 044 motorsport fuel pump various an fittings and steel braided hoses, got my Ecu back from Marc with the 4 bar map sensor installed and chipped for Methanol, 600BHP here we come, and also modified for the RS4 Maf which I still have to rewire. Also not show in the pick is the Aqua mist methanol injection system that I will be installing and running about 15%. I still have to fabricate a stainless steel container for that and mount it in the boot of the car. Still have to fabricate the waste gate down pipe, and exhaust down pipe from the turbo. The intercooler pipes have to be fabricated as well. Lots left to do so I can't possibly make it to BBQ which is a real bummer. I was so looking forward to that this year.

New parts for the Audi Project

Ok worked on the car for some time today I pulled everything off I.e. Turbo headers and finished installing the MVS 44mm waste gate with just enough room for the coolant and oil lines to clear the waste gate. I plan on a straight pipe off the waste gate to empty into the atmosphere here are some pics of the waste gate installed. Things are coming along slowly.

[scubadave]

glad to see progress Nate. just wish I didn't have to tear mine down again over burning some oil. at least a new clutch is part of that scenario.

glad to see progress Nate. just wish I didn't have to tear mine down again over burning some oil. at least a new clutch is part of that scenario.

What is the culprit for burning oil? Bad rings or valves? At the very least it is not a huge job. I did mine in one day head off valves changed and lapped then back together with a new MLS gasket. Is your clutch gone the way of the Aztecs? If so check your slave cylinder while your in there if your putting a heavier pressure plate.

How is the coupe running as of late any way?

[scubadave]

just had head gone through. new ferra ex valves, 3ang plus back cut. head should be perfect. Turbo is fresh. I believe its rings. Its ok as I have them in hand as well as coated rod and mains + arp main studs.

clutch wont hold power of the E85 crack pipe lol. which doesn't sadden me for some reason. read the last few posts of my thread and get the whole story.

Joe would be proud!

I was able to get some work done today. I got some of the inter cooler pipe cut and welded and got the 044 Bosch fuel pump installed. I had to send my turbo back to Hank due to some compressor housing issues so this is all I am able to mock up. I have my header system being thermal coated inside and outside that should be done very shortly. I also got the RS4 maf wired up with the new maf connectors so fairly productive today. Here are some pics of my efforts.

I got the exhaust manifold back from thermal coating today. It is the wrong color but I am ok with black. Both the outside and inside have been coated to reduce egt by as much as 50 degrees. The coating is able to withstand 2,500 degrees F without browning. I am mocking up some other things with carbon fiber but I will wait till their finished to post the progress.

[PRY4SNO]

Looks delicious... what colour was it supposed to be?

[araipilot]

It was supposed to be dark grey or silver black was my last choice but it looks ok so not to big a deal. The entire reason was the thermal protection so the color really isn't important.

Today was spent trying to wrap my head around the methanol system. I decided to go with stainless instead of a plastic container. I looked into prices for t-304 stainless fuel cells and it was $800 and up! Just went to the local metal shop and picked up some stainless and got to gettin. This container should hold approximately 4 gallons and will sit under the spare tire cover. I welded a 5 degree angle on the bottom with angles on each side so the fuel will naturally pool towards the pickup.

I got my turbo back from hank today so I started welding up the 3" down pipe with v bands also put a v band mid pipe so removal can be done without having to remove the axle or have the car up on a lift. On a different note I finally am dialing in my tig welder with some better results.

Today was spent fitting the exhaust up so I could fabricate the waste gate pipe. The exhaust had to be in place so I could see the allowable room for the 1.5 inch waste gate pipe. The wate gate will be dumping into the atmosphere so it give it that ridiculous sound like you've open hells gate. Here is the progress.

I got all the piping done for the inter cooler and the air filter. I had to buy a bigger air filter and a tight radius 90 degree bend. Almost ready.

[PRY4SNO]

Looks niiiiiiiiccceeeee.... really digging on the orange heat shield jackets, any links for those?

[Audilard]

034 sells that heat shield. It comes in gray as well.

Nate, I found your project thread again! Nice work!

[araipilot]

Cheers Darin,
A lot of work but it will be a think of beauty! pry4SNO you can buy the heat shielding from 034 as Audilard has suggested. As fabrication goes there is a lot of redesigning parts or changing locations so everything can fit. You can plan all you want but things change due to space restrictions or other parts becoming more of a nuisance than expected. This is where I am left, I had to buy a short radius 90 degree silicone hose 3.5 to 3.0 to accommodate the RS4 Maf and a new AEM air filter that has a 3.5 inch opening. There was no way around this as I had to keep the diverter valve tubing post Maf and I just plain ran out of space but the new parts will fit, but just. It should be very tidy once complete.

Thank you man, you up in Canada? Looks cold where ever you are. Busting my butt trying to get this thing back on the road. I have been working on this car for about a year now not full time but off and on hoping for about 500 WHP with methanol.

Any way thanks for the comments!

[ringbearer]

Looks great! Definitely getting closer, I especially like the meth tank

Thank you for your positive response. Looks like you have a nice usr4 in your profile pic. Do you have anything done to your car?
