VW/Audi 07K (2.5L 20V I5) Swap Thread
#1666
I think you mentioned in the video a thermo fan switch failed? Shouldn’t the 07K ecu trigger the fans? Shouldn’t the dyno fans provide plenty of air flow for cooling if the rad fans failed? I can’t imagine rad fans are going to keep up to WOT anyway. It was late when I watched the video so I may have misunderstood. Sounds like you caught it early and shut it down, so hopefully just some minor fixes and good to go. Better to find issues on the dyno than street or track. Keep plugging away.
The dyno fans 100% have enough flow o keep the engine cool, but in our excitement to do a run after making some tuning changes we forgot to turn them on. Just an unfortunate accident.

Took the car for a super quick drive today (no coolant ). It was an absolute blast and a MASSIVE improvement over the stock lump. The tuner says he thinks there’s still another 10% power left in it when we get it back on the dyno. The car car actually feels fast for the first time ever lol. Video linked below!

Not to clog up someone else's thread with my stuff but unfortunately those pics are from 2017. Car hasn't run since then.
Intake was, and still is a very nice piece. Cost stupid money to have made though. Disappointing since it's been doing nothing for quite a while.
If I had my time again I'd certainly think very carefully about moving to this i5 Audi platform though.
I know it's early days for Mike and Alan but it would be interesting to get your thoughts on this swap?

Hi Alan. Really like what you guys are doing. Watching the development come along and will continue to anticipate ensuing upgrades and the inevitable issues/solutions.
Haven't looked into it in super detail but imagine that it wouldn't take a lot to pull 600whp out of one of these motors with a bit of time. I think the iron block and smaller space between headstuds should really help avoiding headlift when screwing the boost up at a later date.
I'm sure there have been plenty of guys / shops pumping these motors up all over the world.

- Configuration - if you don’t mind working the plumbing in the stock 944/951 locations you can use an existing radiator for a 944/951. I think I’m going to stay with this type.
- The only off-the-shelf rads out there have two rows of 1” tubes so cooling capacity is unknown for higher powered guys.
I purchased the same intercooler as Alan (Frostbite) and will give it a try. Good price and almost perfect fit.

I have a few options in the works, but to be honest there are two hurdles for radiators.

For anyone interested, I can do a group buy of at least five (that's four of you plus me) of the complete cooling system for $1800. My cost is $1777 plus shipping, so call it $1800 to the group here plus freight from Milwaukee to you. Are there four seriously interested guys here? Here are the pictures:

Craig, the $500 rad sounds like a better option to me. I think that's about where we would land with the radiator I said I could supply (same layout as the Griffin one I customized, but sized to fit stock 951 mounting location). If you're going to supply them, I'll probably stay out of it (I have enough on my plate as it is).

Mike and I got to drive his car at Putnam Park Road Course yesterday. The thing was a blast and we got a lot of compliments about the engine installation and the sound it made on track. It felt comparable in power to my 951 when it had the stock engine (except that it didn't heat soak the intercooler and go into limp mode ) and lap times were about the same as well. Oil pressure and cooling was great. The only issue we had was the front serpentine belt. If you're following Mike's youtube videos, he explains it. Very annoying problem, but we have good leads on how to solve it with some different pulleys.
I can't wait to get my car on track with the turbo... double the horsepower will be even more fun.

How strongly does everyone feel about the radiator location and having both connections on the left? A few considerations, please vote!
Looking forward to everyone's opinion.
- I am planning to have my intercooler mount just rearward of the stock 944 radiator location, and the radiator just behind that. If I come up with a mounting system for this is everyone OK with this setup?
- Wizard can build a radiator same as their current offering, but with 2 rows of 1.25" tubes which they say will cool 500+hp, for $150 extra (figure $700 without volume discount for just the rad).
- + known quality name brand, can be used without a special mounting system if you are putting your intercooler in the bumper (or going N/A like Mike).
- + can use 944 fans/shroud as direct bolt-on
- - have to plumb the lower hose from the bottom right (Mike did it, I don't see this as a big deal)
- - $700
- Griffin has a radiator that has both connections on the right with a fill cap, 22"x13", with 2 rows of 1.25" tubes. This has similar dimensions to the Wizard above (slightly smaller), and I've asked for a price to remove the filler and swap the ports to the left.
- + less expensive (the standard version is $274, plus customization, total should be a few hundred less than the Wizard)
- + both hose connections on the left side
- + known name brand
- - would need to make a shroud and mount fans, or adapt the 944 setup
- - would need to add cost to put in the 944 fan switch port if needed (could also mount in an inline fitting in the hose run)
- - less straight forward mounting scheme
- - not quite as big as the Wizard, so cooling capacity?? at high loads and low speeds unless we use higher CFM fan(s)
Looking forward to everyone's opinion.
