I just wanted to find out what you guys are doing as far as big power mods (upgraded turbos, or turbo kits). Wanted to find out what you guys are running..

I have a AMS 3076 kit sitting here and am thinking about selling it as i'm not sure if it's the best thing for the car. I'd prefer to not be rebuidling the motor/driveline right now..

 

I'm using a stock IX turbo for TTS. You need to decide what form of racing you want to do and what class you want to be in - that will determine the type of turbo you want to use. Don't just add a big turbo without first knowing what the rules are going to be for the class you choose.

 

You don't mention what other mods you have, but a big turbo kit is the LAST power mod you want to do, not the FIRST. Start with free-flowing exhaust, 3" downpipe, rally cats or test pipes, and cold air intake. Then bigger fuel pump, fuel injectors, boost controller and some sort of tuning system (such as Apexi AFC). Then cams and bigger intercooler, and maybe bigger radiator (for summer). Then rebuild the block with forged internals.

Then get a big turbo.

 

have you ever driven on a track before?

 

Ha ha ha.. Yes, i do about 10 track days a year, have been for the last 5 years or so.. i'm decently quick.

The reason i ask is that the car goes pretty well in stock form. I bought the 3076 because i got an amazing deal on it, and couldn't pass it up. But, that's also why it's sitting on my floor and not under the hood. I figured the car would be a handful after the install with about 400hp and i'm not sure it really needs it. That's why i asked what are the typical big power mods the track guys are running.

 

I'm still pondering what to do as well.... I have about 333 at the wheels and I love my "fill up and go" reliability. If there is a really reliable way that I can make 420 or so at the wheels I would do it. I'm not too sure you can add a bigger turbo and not worrly about issues at the track.

QuickOne: if you do enough driving on track... an Evo can always use more power. Hell, i'm waiting for the problem of too much power

 

Well, i've had a car with too much power for the track. It's difficult to enjoy track driving when you can even get into full throttle due to a lack of traction. A 600hp rear-drive mustang will do that. End up selling the car and getting a 350Z.

But, with an evo, yes that would be much more difficult. AWD is a wonderful thing..

I think i might have to sell the 3076 here shortly...

 

yup... I would like to start getting some power oversteer in the evo. I would be running a lot faster laptimes if that was the case. 600 at the wheels should do the trick

 

I've driven the ams time attack car a couple times, and it was putting mid 500's to the wheels, and I would gladly have taken more power, as it was not a problem to control i. It is only an issue on corner exits, and a judicious use of the right foot solves that. I think up to 800whp or so should be drivable, but you really better be on top of things if you don't want to put the thing into the woods or worse. More power just means less room for error, but will almost always mean a quicker lap time if you can control it.

Mark,

Do you think the 35R (boost all at once) played any part in the corner exit oversteer?

Maybe we should be looking into a twin turbo road race setup for the evo jk

We have not had a problem with corner exit oversteer. If anything, on throttle push at corner exit is the problem. The real question was how much entry and mid corner rotation were we willing to live with. All that will change this year with the new 65/35 center diff that we will be running. The buildup of the 2nd generation AMS time attack car is being documented in an automotorports thread. Should be one insane car.

Sounds cool..
