Heat Wrapping

Fodera04 · 07-22-2006, 04:28 PM

Whats good fellas,
In the past couple of weeks i have been upgrading, bigger top mount and a new down pipe. the new down pipe will cause some boost creep so i am trying to keep the temperature down in the engine compartment to compensate for it. i was wondering what you guys though about wrapping the down pipe, i have heard that it does good things but i was concerned about the heat not dissipating and being trapped in the wrap and potently cracking ether the DP flanges or the exhaust housing on the turbo.

It's best to wrap the pipe, then spray with some hi temp silicone coating. I wrapped and sprayed my uppipe, then baked it at 500 degrees for a little while. I bought everything from these guys, check it out.

If you have the stock turbo you are not getting boost creep,you are overboosting.Most of it is from the new TMIC because it has less of a pressure drop than the stock one.Why don't you try using some engine management instead of your off the wall compensation fix before something bad happens.

But the heat wrapping is a good thing to do even with engine management.

A engine management system would be the best thing to do for the car but as a student cash flow is just a bit to tight so other cheaper alternatives like heat wrapping would hold me over until the real flow starts coming in.

Its all about the Benjamin's Baby

You obviously totally missed where i was going.Good luck with your handgernade(especially since you have an 04 with OL/CL issues).

Yeah, these are NOT cars to be budget upgrading, and wrap won't fix your problem.

My advice to you is to take the TMIC off until you can buy an EM system.

i agree, a DP on an 04+ MY could be hazardous to your engines health. SEll the TMIC for now, get an AP and go to stage 2 with the DP. Get some cheap wrap and wrap the hot side of the turbo and the DP. done.

There is no reason he can't just run a catless downpipe without em. I ran up/dp for over a year without Em and had no problems what so ever. And really, same thing for the tmic you don’t have to have a tune to run a bigger one. Heck, you could even run a fmic without a tune if you really wanted to. Yes, it would be optimal for you to get a tune, but you don’t need one to run a downpipe. As for wrapping your downpipe, I wouldn't do it. Yes heat wrapping it is the cheaper way to retain heat as opposed to getting it coated but it's also dangerous. I had my powersteering fluid line burst resulting in a fire costing me 2k. The fluid got all over my turbo and exhaust which started it, and it eventually burnt my electrical harness. If I had heat wrap, it would have soaked it all up and made the fire a lot worse. Save the money, get coating.

I'm not gonna agree with that at all.Most TMIC have a 2psi pressure drop at the least over stock one creating a major problem with the ECU trying to control boost.The stock EBC is set with all those parts in place.Cobb's "stage II" map basicly is just a stage I map with recalibrated EBC setting for the exhaust and that is also why they say "stock i.c." because that will change boost controlling abilities as well without tuning.Ya,you run that setup with the TMIC and DP with no EM and once fall/winter start rolling around and ambient temps drop you will really see what overboosting is.Are you just saying you had no problems because your car is still running or because you actually datalogged or had the apropriate gauges (egt,wideband,knock..) to know everything was good?Because if thats the casue all these engine management companies are really ripping people off.Next you should tell Fordera that MBC's and intakes are fine because you have been running them with no problems.Its just all a scam the tuners made up to suck our wallets dry from dyno time.

I see no reason to worry about the Em with a DP or TMIC. Together you may be pushing it but its not going to kill your car or your turbo. I have never heard anyone before say you have to get EM with a DP. Have fun with the DP hold off on the TMIC if you can and get it tuned when you have the money. No worries.

I didn't upgrade my intercooler until I got a new turbo because that is pointless. I did run an up/dp without tuning and the car was fine. There are a lot of people that run an exhaust without tuning and there cars work perfect. The only info I have regarding intercoolers is when I switched from an aftermarket TMIC to a fmic. I ran that set up for about a week and couldn't tell any ill effects of not having a re tune for the bigger intercooler. As far as the original poster, there is really no reason for you to have a new intercooler, the stock one will even support an aftermarket turbo like a vf34. Sell it, and use that money to get a tune for your exhaust. If you can, I would get a protune with the AP as the pre loaded maps suck ass.

hondaeater · 07-28-2006, 08:57 PM

wow a bit of misinformation if i do say so. Here's the real skinny:

starting in Moldel Year 2004, Subaru's hand was forced to implement a fueling delay to a certain % of their production vehicles. The delay is set to run stoichmetric AFR values for an extended amount of timewhen under throttle. The delay is meant to decrease emissions. 14.7:1 Air to Fuel Ratio (stoichmeteric) is the best ratio for a clean fuel burn.

Many with less superior gas (read cali and alaska) have datalogged their cars and have shown anywhere from light to heavy detonation, ON A STOCK CAR.

Removing the DP on our cars really opens up the exhaust, and allows the turbo to spool faster, without any tuning of the WG or WG duty cycle maps. THis could actually create a situation where you could be into full boost, or a decent amount of boost, and still be running 14.7 AFR's. This is bad mmmkay?

The 02 and 03's do not have this extended delay. They have a delay but it has not been shown to be an issue.

One thing the AP does is greatly reduce this emissions/fueling delay, making sure you are running plenty rich when getting under boost to prevent knock or detenation.

regarding TMIC's, a good aftermarket TMIC is a proven power adder to a stock turbo setup once tuned for. It's not too big for a stock turbo, and it's not a waste of money. This has been proven right in front of my own eyes on a dyno. The stock TMIC blows, end of story.

questions?

Indeed, my car had detonation stock, it had it when I upgraded my exhaust, and it had it a lot more when I ran the cobb AP pre loaded map for a vf34. Still, there are many, many people that get a turbo back and do not get a tune, if so many people are doing it I would say it's not as bad as you have led people to believe. I am not telling you to NOT get a tune, by all means if you can afford it do it. I'm saying if you can't afford a tune just yet, you will be ok running the turbo back by it self as many people do just that.

If everyone was jumping off a bridge...... Seriously,just stop and re-read all your posts in this thread.Detonation is BAD PERIOD.Just because your car is still runing doesn't mean damage hasn't been done and doesn't mean everythink is OK.
