You two sound like you need to be in the Bimmer forums. Sorry for sharing an interest in the turns.

I understand people really don't like FI on this forum concerning road courses, but the power can make up for the added weight and cooling can be addressed. Shoot, less than half the cars in the top 30 of C&D's Lightning Lap list are NA.

Considering the title of the thread I wouldn't think people would be lurking here just to give other people shit. Everyone is entitled to an opinion however that doesn't make my opinion wrong. I think perfectly balanced track cars are awesome. That doesn't mean I'm going to build one though.

Maybe for this particular section people either 'lurk or simply stop by on a semi-regular basis because the section title is "Road Course, Track, Autocross, HPDE".

OP is in the midst of deciding which of two ways to go here, which invites any and all reasonable comments. Skepticism included, which is something that only hinting about showing up at a track day as a never-done-this-before newbie with a big power car (and its potential for throttle-induced oversteer) can't help but attract.

The biggest issue is keeping it cool. Extra HP is fun.

You will want a tiger racing style hood. Cooling is going to be the problem but that can be overcome

Agree, I've seen 800+hp Nissan GTR's run a full 30min session at COTA without puking their fluid or boiling the oil, so we need to just cough up and buy the necessary parts to keep everything cool.

Just tell Porsche turbo race cars don't work......

Come at me Bro!

Come at me bro!
Lol- totally just joking.
If you go fast long enough you might get bored. One day, you might find that unless you started driving at age 7 in karts you might never be the fastest out there. Sooo sometimes, and just here me out; sometimes the extra hoonage on tap with FI is just that much fun.

... so we gonna have a "light hearted" FI vs NA stang grudge match at COTA?
Harris Hill?
Or maybe safer, just lap times at Dollahites East Austin track?
... theres also Big Bend open road race but that might favor FI too much.

$20 says no matter the lap times, everyone would love to hoon a Whippled GT around turn 1 at COTA full oppo with tires smoking...
$100 says theyd luv to do that while passing an old guy in a Z07 on the outside.
:cheers:

I'll play . . . now pay up.

If you can't see your way clear to getting 69 y/o me into a C7 (make it a Grand Sport), I guess I'll just have to settle for $20. :lol:

:cheers: anyway.

This^ big reason I turboed the miatas and ran the piss out of them. Its a freakin art keeping them cool but totally worth it

You can make anything *work* with enough time and money. But turbos are proven more efficient in the long run. SC's are great for grunt out of the hole, but that's not really road course work, is it? You're not gearing up for small bursts, you are gearing up for 30+ minute sessions at high RPM's. The SC has great pull down low, but the turbo is much better high up. On the track, the turbo is always making good power because you are always above 3-3.5k RPM's. You are never on the SC's optimal power band on the track.

So why not turbo, if you are interested in DE's?

For me, it's because it still demands anticipation further in advance for going from maintenance throttle even at 3500 rpm to wide open power with full boost. Too non-linear, and for me that just isn't much fun.

You might be a bit too worried about turbo lag and onset, which any competent road course tuner can eliminate. Never was a problem for me in my EVO even at 28 lbs of boost, largely thank to the road race tune. But I don't want to dissuade you. While you are choosing the hard road here, I'm interested in seeing if you can succeed. I've never seen an amateur, self-funded racer win big with a SC setup, but then again, I've seen all kinds of wacky, counterintuitive stuff in racing, so who knows? Good luck and let us know how things go!

Brian and Paul FTW!

Isnt this a rear mount single turbo S550?
Pretty sure thats a wicked quick FI platform.
