EGTs in STi at track days....
�
�
Hey all,
Just did a HPDE at Pocono South last friday and was monitoring my EGTs quite a bit, but i'm a little unsure as to whats safe and not safe. I've read quite a few different opinions.
Anyway, car isn't stock: 20g turbo, PE 850s, walbro, turbo XS stealthback w/ high flow cat mated to prodrive axelback, Spearco TMIC, UTEC w/ wideband, perrin uppipe, perrin inlet hose, perrin drop in filter and removed intake resonator. I [URL=http://www.swaintech.com/header.html]swaintech[/URL] coated the stock exhaust manifolds, the perrin uppipe and the TXS downpipe. I still have the stock heatshields around the coated manifolds and the EGT sensor is about 3-4 inches away from cylinder #4. I was running a conservatice AFR map that day at 10.5-10.6:1 at WOT. Boost spikes at about 21psi and tapers to apprx. 18 by redline.
Track temperature was at least 95 degrees and i was hitting around 100-105 mph on the banked oval in 5th gear. My EGTs were hovering around 825-875 degrees celcius on the main straight. There were times however when i would lift off a little in the straight and the EGTs would quickly rise to around 900-950 C due to the AFRs leaning out a bit when lifting off. But EGTs would quickly return to 825-875 once on the gas again.
I'm just wondering if this is normal or not since track duty can be quite taxing on the engine. Also, do the swaintech coating and the heatshields there affect the temperature since it's keeping more heat in? I hear EGTs anywhere from 1550-1650 F(850-900 C) is the most you'd want to see. Any input would be much appreciated.
Thanks in advance,
Tom

950 is :eek: from all i gather.
how many miles have you put on the car this setup? How many track sessions?

950 C = 1740 F
Sounds high to me. I have full exhaust/intake. Before headers I ran EGT's max ever at 1550 F. With the borla headers I am somewhere arond 1470 F
High EGTs are abusive to pistons from what I have heard amongst other things.

I agree. I would not expect this motor to last too many track days with temps like that.
crystal can you tell me where you probe is located?

Hey,
Well the thing is, it only peaked there for a very very short amount of time off the throttle. It was not sustained at all.
That was my first track day with this setup and i was driving with this tune for about 1 day before.. It was running strong all day and the car was a beast passing just about everyone on the straight in my group including 2 '04 SVT cobras(granted they aren't the best car for a tight infield like pocono south and of course the nut behind the steering wheel matters too). Again, why are they high if my AFRs are still pretty rich and boost relatively low? Timing i believe is right around where it should be at ~25 degrees in the upper rev range. I'm starting to think that the swaintech coating plus the stock heatshield may be affecting the EGT readings. Does anyone have any experience with this? It also was hot as hell out there that day so that doesn't help.
Would like to hear more thoughts.
And V6, i think you're all right man. Forget all those little kids in PPB getting upset. Tell it like it is and keep it real. ;)

My most recent track day was my first with the STi modded. Modlist is pretty short: PDE catted DP, Ecutek custom tune, K&N typhoon intake, Prodrive Axleback.
On the street, my tune has never hit more than 820C or so EGT. At the track, it was maxed at 900C on a full run down the front straight (mid 5th gear). I then went to full up for gas midday and went out on the track again. The day was pretty hot (100+ F ambient) and on my very first run with the tank of gas, I saw my EGTs hit 930ish. I pulled her off the track, mixed in some 100 octane, went back out and never saw over 900 for the rest of the day.
I'm thinking over 900 is bad, but if it's just for short spikes... I'm sure it's fine.

Mods include TXS UTEC + Tuner, TBE, and intake. Max EGT's I see on the street are around 825C even in long pulls, but that doesn't mean crap haha. My AFR's are 11:1 in the midrange tapering to 10.8:1 by redline.
The first session I did with the UTEC installed I noticed EGT's climbing over 925C. The reason being, I had timing locked down in the 0 load sites in high RPM's to prevent shift knock. When I was part throttle at higher rpm's EGT's were skyrocketing. Make sure you don't have any timing locked down in your 0 load sites, let the ECU control it.
Once I changed that, my EGT's never go above 900C at the track. You're probably better to run a little higher octane and try to run a little more timing.. Also, you might want to actually lean it out some since you more than likely have residual fuel burning in your exhaust from running so rich.
Lastly, try not to run too extreme of boost in the top end since the turbo will be blowing hot air. My setup runs 1.2Bar in the mid and tapers to .85 at redline.

Saludos,
I have been running STI's on track days and time trials since they arrived. We also have run programs for customers also. Mi opinion is that since you're running on stock manifold those temps are OK! remember that the stock manifold maintains more heat reflecting on the EGT sensor at least 50-65 degrees more. When you install a header those temps will go to 825-850 and that's what basically we use to see.
It's nice when I see people going to this type of events, I respect drag but it just doesn't make it for me. I,ve been racing since I was 15yrs old and we basically specialize on track racing.
If you have photo's and if theres anything we can help you just email us.

Tom,
I would say your egts look pretty normal and should be safe. You may not want to lift on the straight but instead shift up a gear unless you can restore some ignition timing or fuel at partial throttle. With a UTEC adding race fuel may actually increase your egts unless you add ignition timing to combat the more controlled burn. Race gas is still a smart move at a track event as detonation will ruin your day much faster than a detonation free engine with slightly high egts.
Keep in mind egts are not necessarily indicative of what happening with in cylinder temperatures but high egts are more a reflection that fuel is still burning as it enters the exhaust manifold. Obviously high egts are going to punish your exhaust components and turbocharger but I think it�s unrealistic to get them much cooler than 875C with your level of modification.
We run a WRX with much higher HP but we also recorded egts well north of 900C this past weekend. During normal tuning runs we�ll peak egts around 900C at the top of 4th gear but on our local track I�m shifting into top gear in the first half of the main straight and this is when egts climb well north of 900C.
Just make sure you run really good oil and that your cooling system is up to the task of keeping cylinder temps as cool as possible. You�re also running your fueling very rich which can lead to oil contamination so consider changing your oil before a track event. Make sure all your breather lines or catch can lines are clamped so no oil hits those hot exhaust components also.
Thanks,
Phil

Brian, thanks for the reply. As for shift knock, what are you doing then to prevent shift knock? Should i just dump more fuel in on the 0 percent column instead of locking down on timing? That makes sense because thats when my EGTs went high was when i lifted off the throttle on the main straight.
I definitely have to find some race gas next time before i go. I was looking for some around pocono but there was none to be found.
As for boost, you have to remember that i'm running a 20g turbo and not a stock one. At that boost level the 20g turbo is not blowing hot air so i think my situation might have more to do with timing, AFRs, and ceramic coated stock manifolds with heatsheilds.
Alcrudojr, I completely understand where you're coming from. Track days compared to drag racing is like having sex with a beautiful girl to having it with the good ol' right hand!:D
But very good to know about the stock manifolds holding in more heat thus reflecting the EGT sensor's readings. Like i said, that stock manifolds plus a swaintech coating and the heatsheilds must affect the readings somewhat. What i would really like to know is if anyone has experience with coated stock manifolds and EGT readings. Anyone out there?

Phil,
thanks for the informative reply. I do change my oil before and after every track event with 20w-50 castrol GTX to play it safe. My cooling system is completely stock with regular coolant in it. But otherwise good to know that my EGTs seem normal to a reputable person.
Honestly i was trying to short shift the most i could throughout the whole day just to give me peace of mind. But there were times(many i might add :banana:) that i was passing people on the main straight and had to keep it in 5th the whole way. During those situations my EGTs were right at 850-875 C. It was those times when i was pulling on someone at the end of the straight that i had to lift off to avoid hitting them. That's when the EGTs spiked at 950.
Honestly i still need to get a professional to tune my UTEC but there isn't anyone by me that i trust. I did go to someone that is supposed to be reputable but i left unconvinced.
On another note, after every session i would keep my ignition on the "on" position to have the fan kick on if need be. Well it usually always does but compared to my cousin's 05 STi that was there it was on for half the amount of time his was if not less. I'm not sure if that means something or not but my car needed to cool off less.
Phil, any experience with coated stock manifolds?

Yep, just add a little more fuel in on the 0 load site. Forgot about the 20G, boost away :D

I'm hoping that the Defi BF gauges came with the better one. I'm assuming that it did because the gauges read past 1000 C. And also because they are expensive as shiite!

what you need to do believe it or not, is actually lean it out a bit more, and maybe add a little bit more timing.
if you timing is really low, and your dumping fuel.. It really heats up the EGTS!!
BTW: more psi (pressure) means more heat. more cfm means more volume, volume = hp.

you know, dropping the boost a couple PSI would do huge things for track day engine survival odds and would decrease the fun factor hardly at all..

900 c is what I also see peak at the track. Just like you it is only the peak at the end of the straight WOT. Very typical over the last 6 track days. No problems so far.

[QUOTE=tm999xxx]nice...mine is silver...I just signed up for the 27th... I would love to see how your 20g pulls on the my 39 around the bowl[/QUOTE]
Very nice! I'm sure it would pull fairly well. At least it was on my cousin's stock 05 STi :devil: Unfortunately i'm not going to be able to make that one because of a wedding. But i'm most definitely going to be at Watkins Glen in september and Lime Rock in November.
I actually just made an appointment to get tuned at Turbo XS on August 20th. I will have less worrisome track day after that tune. ;)
Anyone have any experience with Turbo XS tuning their car?

Yes dino oil. I'm not a fan of synthetic and never was on the subaru. Almost everyone that i know of or read about that has switched to synthetic on their STi has complained about oil consumption. Oil consumption is so far non-existent on my car and i plan to keep it that way. As a matter of fact, most tuners/gurus recommend not putting in synthetic oil in the STi as far as i'm concerned.

I second that. Regular oil, frequent change is fine. The Subarus are so clean running compaired to other cars I've owned (dirty GN motors, instant black oil)

... oil consumption is the least of your worries running an engine as hot as you are.

Odd. I changed to Castrol 10w-30 and it burned a ton, almost a full quart. I've since been on Mobil1 10w30 and it hasnt dropped a tick on similar mileage and auto-x events. I *think* the sythetic properties help it not to cook off in the turbo lube line.

That's why i use 20w-50. I don't like synthetic, plain and simple. It's a waste of money for my STi in my eyes.

Very good. I actually did tell them that i track my car and Jermaine mentioned that they would make a nice track day map for my needs. Looking forward to it.
WRXedUSA,
It is odd, but i've honestly heard of more people burning off synthetic as compared to dino on STi's. Do you have an EJ257?

maybe someone who knows can chime in.

It would be nice to have! Actually i've been thinking about getting an oil cooler kit. But i don't know if you read my previous post on the first page, but i mentioned something about my car cooling off compared to my cousin's stock 05 STi:
"On another note, after every session i would keep my ignition on the "on" position to have the fan kick on if need be. Well it usually always does but compared to my cousin's 05 STi that was there it was on for half the amount of time his was if not less. I'm not sure if that means something or not but my car needed to cool off less."
I do have the swaintech coated headers, uppipe, downpipe and stock heatsheild. That probably has something to do with it.
