Ok... Super happy ,,, so first time out with the C70 Coupe 5speed tonight. Seems to run well... hooked up the boost guage.. have a tune from ARD ( BLUE ) went to an 18T turbo, IPD intercooler, and I'm running 15llbs> not sure if that's where it's supposted to be with an 18T.. but that's as high as It got .. Still some things to hook up and fine tune.. It seems to really rip and pull very hard all the way through... I pulled her into the garage and popped the hood... and the turbo was bright red... Is that normal??/ If you could let me know the help is much appreciated.. : )

Should be about 18psi boost, you may have a leak or something. Glowing turbo is normal but if you're running the car hard you should drive it sanely and keep it out of the boost for a few minutes before you shut it off, or let the car idle for 2 or 3 minutes. Its bad for the turbo and your oil to shut the engine off with a hot turbo. What exhaust and downpipe do you have?

[Patric200]

thanks so much for the reply.. I thought it should be around 18 PSI too.????/ Although I don't believe that the Wastegate is adjusted correctly to be honest... will that affect boost at all... I think it does..??/ Anyway,, I have an Euro Sport Tuning, DownPipe and exhaust from Turbo all the way back.... it is an angle flange conversion. EST Air Intake, and an IPD R.I.P ( which I think does nothing ) Kit. I did stage 0 on the car first,, Plugs, Wires, Coil.. ect..

[Jardim]

Yeah man i'd check the wastegate, if that doesnt work check for vaccum leaks.

[TRACStar]

If the wastegate is too loose it will limit your max boost. No matter what your tune/boost controller set for, exhaust pressure will push it open if its not tight enough.

Last turbo swap I did I was limited to 12psi until I tightened the rod.

[gmsgltr]

i have never had a glowing turbo, even after multiple 1/4 mile runs... you must have really been getting on it often haha

glad to hear the 18t is strong, im doing one soon as well!

[RobT5.]

Never had mine glowing
Ive ran it up to 20psi before so its def capable of going over 15.
Check for leaks and your waste gate.
And did you adjust your timing per the tune?

your not running a boost controller? Manual or Electronic?

The blue tune with 18t should be at 18psi as well. since mine is.
I would check with lucky since he is the one who programs it.

Edit... Site says 18psi.

Blue - Tuned for 18psi and is intended for cars with either the 18T, 19T, or K24 turbo.

[850T5M]

Like everyone said, should be around 18PSI.
Do you have a wideband meter?

If you just installed the turbo, I'd wait like 100km before really beating on it...
I noticed that when I installed my 16T, it didnt boost well for the first few days of driving, it slowly started working better afterwards.
Maybe it had to oil up well lol, idk...

Enjoy the car!

[Patric200]

Lol.. I will,,, the wastegate does seem very loose... I'm having it correctly adjusted today... I'm still not sure if it's cool for that turbo to have been red..? lol I know I have some vacuum leaks to take care of.. and I think I have a leak to the vacuum line going to the fuel pressure reg..?? or something... Keep bringing any suggestions! I appreciate it..

Did you adjust your timing per the site I link'd?
And do you have an wideband to monitor AFR's?

[Mesoam]

do you have an exhaust on the car?

Turbos are designed to run red hot, why do you think turbo timers were invented? After driving like that remember to keep the car on to let oil flow through the turbo while it is cooling. If not the oil will sit in the turbo and 'cook'

[Patric200]

ok great.. so red is good,, just let it sit before I shut it down do the car can circulate the oil through the turbo.. sweet... As far as the timing it will have to see if he adjusted it to the -1 degree from that site.. and to Mesoam.. it does have a full EST downpipe and exhaust all the way back.. I'm new to this and don't know what a wideband.. or AFR's are.??? lol any explanation would be awesome.. : O)

[BoostedS70]

what kind of boost management are you running stock TCV... if so stock boost mangement is sub par if best IMO. i would reccomend you get a gizzmo IBC-R so you can really fine tune it. MBC are no good either as you will make boost way to fast good luck

and it being red is neither good or bad its just normal under heavy boost lol. your EGT's will reach over 1000 degrees F under full boost.

[Commander Riker]

What year is your C70?

[Patric200]

It is a 98 C70 Coupe 5sp. I only have the stock TCV.. guess its time to upgrade to something else... Lots of loose ends to still tie up.. The car Ran a 13.92, before I did the angle flange, 18T turbo upgrade and bigger intercooler.. I went to ARD and gave Lucky my build specs.. and he tuned up my ECU for me !! I was hoping to see maybe a mid 13, or even low if I had a good launch... Just have to make sure it's managed correctly before I try that again, : }

Did i say somthing wrong or give out some false information please tell me.

[BoostedS70]

stock boost mangement does suck ask anyone and they will tell you. if it was so great no one would go to any other boost managment . and egts do reach over a 1000F on full boost. i have put down couple 100 miles in canyon runs and my turbo is glowing most of the time when i stop. just means some of us men know how to push it to the limit . so i guess i gave out some bad information. FAIL... sorry to the OP listen go get urself a ipd HD TCV not saying its the problem with your boost its most likely the wastegate needs some pre-tension. but its a good upgrade if your going to be past 14psi. as factory boost managment is weak. if you really want to get fancy get urself an Gizzmo IBC-R electronic boost controller and you will have alot more control over the parameters of the boost and turbo itself.

[Patric200]

I will look into the Gizzmo boost controller... Not sure how they hook up to anything.. but I'm sure it's not bad...

[SeedyRom]

At what RPM does your boost start coming on? If it's too early, might need to adjust the wastegate. I've been holding off on an 18t upgrade until I get a wideband AFR gauge. It's to measure how much fuel/air comes out of the exhaust. This will tell you if you're running too lean or too rich. It's possible you're going lean and causing such high exhaust temps because of it. Especially since you say you're having a vacuum leak to your fuel pressure regulator.
