I never let my students take off traction control off......

 

I should clarify. Those HPDE 1-2, and 3 (if they are new) until signed off, I agree. Anyone (thus HPDE 4+ prepping for comp school, TT or private students, we'll phase it out.

It seems there's a difference between the Evo X ASC/ AYC traction control systems and, say that of a Corvette or BMW (Porsche too) such that it's difficult to teach certain skills in the X with AYC on.

 

I just noticed this note. At 86 db/ 50ft you'll need to keep the exhaust completely stock to meet restrictions. (I think PCA gets 88db, right? Lucky). Maybe a couple of other guys here can chime in regarding LRP, but I know (as I'm sure you do) that a number of stock cars can't make the restriction at WOT (R8 for example, and the new Camaro). Just something to watch pretty closely.

We have a dedicated exhaust with resonators and two small mufflers into special downcut tips to meet the restrictions. It seems to weigh about 800lbs but gets it done. The tune for that specific exhaust only gives up about 6hp, but the sound limits are a real pain.

 

I won't put a special muffler on my race car to just run LRP. When we race there with PCA, the event is unmuffled. The noise restrictions laws at LRP are getting out of hand.....

BTW, in porsches the traction control is pretty lax, no need for a new student to take it off... especially when I am on the right seat......

 

Im thinking I'll push as hard as a feel comfortable with in ASC mode and see how it goes. If the throttle limiting is slowing me down too much i'll switch to the first OFF position. Im not super comfortable drifting or controlling 60mph tail "kick outs" yet. Will keep you guys posted! Thanks for the input

 

Sounds like a smart move on your part, especially if this is your first time on a track......
have fun!

 

Agreed, LRP is a disappointment - a very nice track, verdant, close, and as it were, one of the only locations with races in which I can coax my wife to attend. The unmuffled HPDE days are fun. Typically we just go where the season's events take us, and if that means LRP on a sound restricted day, that means the big exhaust comes out.

On the TC. Yes, that was my sense too. The Porsche's seems much less invasive than the Evo's. I suppose the Porsche might not save you as well, in the event of driver error - and leaving it on is smart while in the suicide seat.

 

Obviously one of the benefits the ASC is for safety and it makes you appear to be a better driver. What I notice was that the ASC kicks in pretty quickly where you have made a mistake in your line and start moving laterally with some steering wheel movement. With the proper instruction, wit the ASC off you will learn how to better manage the car versus the car managing your mistakes for you.

The difference I noticed with the ASC off versus on is when it is off you get oversteer;however when you have the ASC and perform a lift-off oversteer to powerslide the car (and smoke all four tires) you have to keep the wheel fairly straight otherwise if you steer the powerslide the ASC voilently calms the car down. I tried this a couple times and do not recommend it since it is hard on car.

 

i havent had any issues at LRP with an invidia q300, hfc, and downpipe fwiw. i agree though thats its getting out of hand with the sound restrictions

 

I've done a track day at homestead. It was probably the most fun i've had with pants on. My car was bone stock (suspension/brakes wise) with the exception of tires. I had hankook rs3's and they worked great. The brakes faded about 20 minutes in so I would recommend cooling ducts. I did find the stock seat belt didn't really keep me in place well. So harnesses might be a good upgrade too.

 

Yes, the Evo X chassis actually passes certain FIA tests without having a cage added, but that doesn't mean you should throw any old harness in there. I strongly suggest a Schroth Rallye-3 or -4 harness because it is made to stretch only the inside shoulder in a crash, such that you roll forwards (slightly) and towards the center of the car. Obviously, therefore, you need to get one left- and one right-side harness. Never ask an instructor or anyone else to be less safe than you are.

Try better pads and maybe the Mitsu air-deflectors for the front lower LCAs before adding ducts. You might not need them.

 

I took the TC off my Jeep SRT8 when I took it for a spin at NJMP

it definetly adds to the fun, but like you said, not when on the right seat.....

 

That's actually very good to know. I think having the cat helps a bit, even though it is HF. Does the Invidia have a resonator as well as the muffler?

 

Yikes! That's good fun. Do you recall your lap times at Thunderbolt? Wait, I can see it's about a 1:44 with the chicane.

 

That sounds about right, I can't believe it is a Jeep, the brakes were cooked after 1 session......I am about 10 secs faster in my racecar

I bet you run in the 20s with your EVO......
