Well 3 years and 1 motor later I figured it's time to start a member journal.

I don't have all that much done to the car, nor do I plan to do significantly more.

After my motor let go and I got a new one and was thinking about getting rid of the car.
I've since decided to keep it and give it another shot. My main goal now will be to simply make it autocross and track reliable. Or as reliable as one can get it. Otherwise it seems pointless to keep the car.

Since it seems stupid to keep doing the same thing without changing anything and expecting a different result I will keep a log at my attempt to save the second motor from the same fate as the first. It now runs on the Stage 1 91Oct LWG Cobb map with 93 octane fills. Likely to be tuned conservatively some time in the near future. I won't be taking the car out on track until I'm confident it can run autocross to my satisfaction.

Heat management will likely be the primary issue I'll be facing. Beyond that this will be my driving journal more than anything else.

Re: severe STI - it's about time?

First event of the season. Ran it mostly in S.

1080p on youtube.

Re: severe STI - it's about time?

My goal is similar to yours so I'm excited to see what you will do to you car to make it more reliable and fun to drive.

Also, is there a reason why you ran in S and not in S#? Heat issue? Power understeer?

Re: severe STI - it's about time?

Mainly precaution. They're boost select maps so S has near stock boost levels, where as S# is about 2lb's more. I still have logs from the event to check, just haven't had time. It's the first event on the new motor, so taking it easy so to speak.

Re: severe STI - it's about time?

Two rolls of DEI cooltape on the way.

I had thermotec tape on the IC before but it de-laminated and fell off.
Going to clean it up and reapply and hope this stuff is more durable.

Also will try to figure out some way to shield the air intake tract. I doubt the tape will stick to plastic so may need need to DIY some shields.

Re: severe STI - Heat Management Step 1

Got my cool tape. I like this stuff way better than the thermotec tape I tried before. Sticks better, thinner so it conforms better. Hoping it won't delaminate, but I have high hopes. I definitely don't recommend thermotec tape at all.

Re-wrapped the IC to start with.






Also noticed it sticks well so I decided to do a week test run with small patches on airbox and pre turbo inlet hose. If this holds up on plastic and rubber it will make life much easier.



Dealer broke a bunch of heat shield bolts and it rattled something awefull, so I replaced it with a manpon turbo blanket. It's been on for about a month or so and seems to be doing well. No issues with the actuator arm either. It looks bunched up, but it's actually barely touching. Looking at aftermarket heat shields in the mean time. Front 3 nuts are still good only the lower ones are screwed.

Re: severe STI - Heat Management Step 1

Interested to hear how the DEI tape holds up. I have a roll of their gold tape, going to be using it for the same purpose.

I know it's more money, but DEI also makes a cool tube blanket, for intake tubing. Waiting to put mine on.

Re: severe STI - Heat Management Step 1

I ordered another 60foot roll of the DEI cool tape.
It's already doing better than the thermotec stuff and plastic and rubber patches both holding up perfectly. Hopefully I get it in time for the weekend for Step 2 :)

Re: severe STI - Heat Management Step 1

I put DEI cool tape on my IC and the under side of my Cobb turbo heat shield almost a year ago, and its still holding up just fine. I also put a turbo blanket on as well

Re: severe STI - Post break-in compression test

Since I was changing the battery, working on the intake tract and changing plugs I did a compression test for the hell of it.

About 4k on the new motor

3=146 | 4=145
1=149 | 2=144

I'm happy.

Re: severe STI - Post break-in compression test

Trying to prevent the intake track from heat soaking the plastic when standing still. Fans blow a ton of hot air at it and there's a ton of heat radiating from the motor. I left the left side without any tape since there's no real heat source there

I was debating whether to do a heat shield or not but the DEI tape holds well. I figure I just throw it on the stock box, under the snorkel and the pre turbo inlet hose. We'll see during the next autox how far temps rise between runs.






A pic of what happened to the Thermotec tape:

Glimpse of a little side project I've been working on here and there.

Re: severe STI - Post break-in compression test

Why you shouldn't let the dealer work on your car. EVER!!!
This is what they did during the motor swap:



Seriously guys, what the ****! How do you even manage to break the tabs on the coil pack. Those clips come off easy. I'm debating whether or not I should go there and demand 2 new coilpacks.

Thats pretty epic. I had done the underside of the snorkle before i got my AEM intake, but never thought to take it as far as you did. will be interesting to see what you learn from the autox tests

Re: severe STI - Lots of updates: Heat Mgmt Step 2 | Amp/Sub Rack | WTF Dealership?

First of all great wrap jobs with the heat tape! Second go get new coil packs! thats a load of crap

Cover the MAF also, if you want to make the biggest impact. IAT's are read there and ignition tables are calculated off of this reading amongst others.

I have a small fortune in heat insulation so I'm a believer in DEI's products for sure. I have everything covered imaginable, from EWG vac lines to headers all the way back to the muffler.

I like how they zip tied your coilpack harness on like you're never going to change your spark plugs and find that. :lol:

Second event is this Saturday so we'll find out. I actually somehow missed the first event with the bmw club :(

It seemed to have made a difference to touch, also looks like cruising speed temps dropped a few degrees. I haven't really monitored them long enough to have a good baseline but once I stop the temps still seem to get up there

Thanks, yeah we'll see. It holds, I had to put them back in the same way...

Yeah i figured they would reuse the plugs from my failed motor which is why I decided to change them to begin with. I was right.
Thanks for the tip perhaps that's why I'm noticing the high temps still while sitting. Though the top of the MAF doesn't see all that hot, at least not 120+ hot. Inside of the plastic pieces isn't nearly that hot either, perhaps it's sucking in radiator air from that opening where the snorkel meets the box. Not sure, yet.

I hope they didn't reuse your oil pump or oil cooler also.
TBH I never noted much inlet temp difference with any and all of my heat tape with the MAF measuring IAT. Its pretty much useless using that as an IAT reference point anyways because its always going to change and never be the same once that air is pressurised and passed through the IC. I've really based my results off of surface temps taken with a radiant heat gun while we were on the dyno. Along with that just basic before and after underhood temps as a whole.
If you're looking for another quick cheap mod to beat the heat if you havent done so yet look into blocking off the coolant flow to the throttle body. :tup:
IMO it kind of defeats the purpose to have cooled charge air and then pass it through a constantly regulated 180* throttle body.
