upgrading brakes, suspension componenents and before you know it you
are flat broke (oh, wait, maybe that is just me??).

It would be fun to make those choices though!!
Well said Marty!

Whatever happens ............ so be it.
Chad,you will also need a NHRA license to run the times that car should be capable of.

How much more horsepower can EVOMS make by using the air intake plenium that goes behind the motor to feed the turbos? It would seem like they are getting to the edge? Or maybe I am wrong? When I look at the supras motors they have huge intakes.. much bigger than what we can put in the conventional way but the only other method is what Protomotive uses in which the put the tubing into the fenders? What do you think?

For making really big power (I consider stage 4 very fast, anything above is really big power in my book) there is really no comparison. Protomotive builds/tunes are custom (IE not canned) packages that make more power (of course usually cost more) and are more reliable. I personally know of several blown engines and a host of problems when you get beyond stage 4 in the EVO packages.

The sub 10 GT800 was a great achievment, but it doesn't quite hold up to the top custom builds (like Marks and Scotts") that proto has done. Sorry, but that is a fact. It was a purpose built drag car, not a customer DD. Also, it is one thing to have Todd Z hand tune a GT 800, but another when that tune is done remotely.

Again, I highly recommend EVO for stage 1-4, especially now that they have solved the MAF problems. I also give top marks to many of the EVO products, like their IC's. And many of the EVO guys are outstanding individuals, but ultimately I would want Todd K to tune my car.

I am now donning my flame suit.
Another brilliant post, Sean. You're on a roll!

Chad, take a look at the 2007 NHRA regulations thread.

If you kick off all the "**** talkers" and then in fairness all the spruikers, this forum would be almost empty......

Now that would be no fun at all.

I've been happy w/ Protomotive and plan to stay w/ them.
If one is serious about tracking the car on a road course, smaller turbines will lower your lap times.
At mid ohio raceway this weekend I had get off the gas half way down the straights otherwise corner entrys were way too hot. Coming on boost strong in the middle of a corner makes for some challenging oversteer as well.

..

this is the first time since i joined this board that another member talked about what i learned from track days with my 996tt...

a stock 996tt with stock brakes is too heavy for most fast tracks..

as well as the 996 is engineered, the brakes can't handle the speed/weight after a few laps... at Road America, if driven hard, you would swear that the rotors were warped.. by the 2nd lap, the front tires/wheels felt like they were going to fall off !!

the car was slightly modded with wheels, tires, an exhaust and ecu remap..

it wasn't fun when everything heated up and there wasn't much my mechanic could do about it. Sol, from Perfect Power told me from the start that a street 996tt was not a good track day car (if driven hard) .. he was right and he should know as he has a real Porsche race shop near chicago that campaigns several cars..

i had fun but would have been better off with a race car.. (lighter)

Rob,I don't understand what you are getting at! There are a couple of cars running around in the 750-800rwhp range with that setup......I have it on my car and I don't think that is the limiting factor.The Proto and Evo are 2 different systems that deliver and measure the air in 2 different ways.....2 different philosophies.My car will easily pass a visual and emissions inspection that way with no problems.

A properly modded tt on the right track can be very capable. I had no problems on a short track dusting a Noble which is very light and track ready.

my point was that a street car without brake mods and weight reduction ISN'T being all that it can be..

the difference between a Porsche race car and a Porsche street car at the track is HUGE.

my friend Sol, who "educated" me, has some very interesting Porsche race cars...

That's actually a _really_ important point for us California-wussies. We recently got a 3.8L GT800 with said intake/plenum to pass smog here. It looks so stock-like and the plumbing still matches all the emisions labels on the decklid as well.
