Background:

Old AP1, had turbo installed and tuned from manufacturer of kit. In one year, lost the turbo twice, and downpipe fell off once. Heat from under hood could be felt in cabin big time with aggressive street driving, which is nowhere near track driving. Kit's manufacturer made good one 1 year warranty and fixed all, but 3 issues (on the street) in less than one year has left a bad test in my mouth about a turbo setup having any degree of reliability on the track. I track about 1/month, for 6-10 track days, fwiw.
------------------------------------------------------------------------------------------------------------------------------
Was interested in the KW SC kit, but doesn't look like that's an option for the foreseeable future.

Wondering is there is any reliable FI option left, which is reliable on the track.

Is there anyway to have 2 maps for a turbo system? For example. 350 hp for track use, full bore (425+hp) for street use? The longevity of F22 motor, putting out 400+ hp on the track, makes me cringe.

 

Sounds to me like you have had either a bad kit or a bad install. Typically it is the tuning that is somewhat unreliable depending on who tunes the car. Most of the kits made by various sponsors on this board will be reliable pending a good tune by someone who knows what they are doing. Hope that helps

 

There are many factors to this and OTHER prevent things that must be done. Things I would suggest: Radiator, Oil Cooler, Heat wrap manifold, and etc. Basically things to try to keep the car cool. Something else that was told to me was shifting early, dont always Rev it out. Then the big thing, the tune, like mentioned above its ALL in the tune as far as how your car will last. Having the two maps is also possible as well. Good luck on your endeavor.

 

got a Koyo radiator - been collecting dust.

anyone have pics of their heat wrap?

Whe sells a decent oil cooler?

The install and tune was done by a major sponsor of this forum (hint) - I would hope they know what they are doing.

Hard not to rev it out when on the track - the rpm's climb quickly with a turbo. Sound like what you are saying is kind of what I was looking for (a lower state of tune), just you are keeping the boost low by shifting below max rpm.

 

talk to soulcoughing he just tracked his turbo car at pocono and the car did well.

 

Look at my build thread for heat wrap pics. Used atp wrap in California, first class work. The ptuning kit has been tracked reliably by metros on this forum. I also have the ptuning oil cooler option and it works great. I would say this is one of the best turbo kits to track for a lot of reasons. Good luck with whatever you do.

 

Tracked and autoxed my greddy turbo kit and never had a problem, for what its worth.

 

Ptuning, greddy, vortech, SOS, comptech. All no prob.

Others can work but be careful.

 

Were you monitoring your oil temps? If so, how high did they get? If you weren't monitoring them, you probably don't want to know...

 

We had a local s2ki member have a lot of problems running his greddy kit on track. Even with a nice oil cooler set up (mocal IIRC) he couldn't keep the oil temperatures within check. I think that is largely because the turbo in the greddy kit is only cooled/lubricated via oil. No coolant cooling to the turbo.

The garrett turbos that the PTuning kit uses are oil lubricated and cooled via coolant. You get a lot more cooling properties by running both. I have tracked my car in ~85* weather and temperatures were within check the whole time. Oil temp peaked at 259 (measured at the oil pan) and coolant temps peaked at 210* (measured in the upper radiator hose. That was on my 3rd track day with the PTuning kit, which is important to add because at this point I'm comfortable with the power and starting to really push the car.

Here is my set up at the last track day:
PTuning turbo kit with GT3076R, running 14psi and putting down 422rwhp, dual exhaust, ACT HDSS clutch, Koyo Radiator, PTuning oil cooler, stock thermostat, Staggered star specs.

For those of you that want a different map/tune for street vs. track: The control of the power is via right foot. True rpms climb quickly with turbo. However, it's not uncontrollable and with PTunings kit isn't bell curve peaky power output. Very linear power output, which helps keep the car settled/stable. You also have the option of keeping the car in a higher gear than you typically would in especially tight turns where you want to be especially cautious to keep the rear end in check.

OP - I don't feel an above average amount of heat coming into the cabin post turbo install. That hasn't seemed to change from OEM at all. Even with the top up, windows closed, and AC on in the 110* weather we had last weekend.
