Just wondering what mods i would need to beat my bro in law in his Porsche. The Porsche is a fantastic car (he lets me take it for the weekend sometimes ) It was actually me that convinsed him to buy it. My mods are dp, cb exh, intake, street ported, 255 lph fuel pump. Does it make sense to upgrade injectors before the ecu? Acceleration and top speed is what im asking about not race track.

 

350 Rwhp

 

no get the ECU first. Then upgrade injectors if they are not up to par with the amount of fuel needed for your desired boost level.

 

You will need all the bolt-ons at 13-14 psi with a tuned ECU. Don't go from a dig.

 

Try to take him from a roll if you can. I wouldnt try it standing still! I think you would have to be running about 330 to 340 hp to really put it to him minimum.

This is probably right. The 996 Turbo puts down about 315-320 at the wheels. That's right, they lose about 100 hp from the flywheel. And they weigh 3400 pounds, some 600 pounds more than an FD. But they have LOTS of torque, so the rolling start will be needed.

 

You cant upgrade the injectors with out upgrading to a programmable ecu first.

 

996 turbo is an amazing car it can go from 20 to max speed in sixth gear with ease!

 

I drove a 996 turbo all summer. My brother has one. I would guess that you would need at least 400whp to even stand a chance on the highway. My car is a little over 430whp and it just might be a little faster than the stock porsche was.

A modded 996tt? That's a different story. My brother putt on stright pipes and a new ecu and gained a little under 100whp!!And no matter what people think. The 996 turbo is an extreamly hard car to launch. I would bet that even from a dig an experienced rx-7 driver could keep up.

 

yeah that is true they are hard to lanch, its on the second clutch i think or third. he bought it used and abused i think dont tell him i said that though

 

I really don't think you need a 400hp fd to beat a 996. I am not debating that the car is fast, because it is, but 400 is a bit high. Just my .o2 thoguh

NOT. An FD in the 330-340 rwhp range should easily keep up with a 996T. At 430 rwhp, your car should be raping a 996T.

 

yah, all that aside, i dont think he has 330-340whp with the mods listed.. then again, im usualy wrong

 

well i guess well just have to see this summer as my car should be putting down about 330 rwhp. thanx for your opinions fellas

 

I read a couple of specs on the 996, and I think you do need 400+ to take it.

 

well alot of it comes down to the driver and not to toot my own horn or anything but im pretty sure i can out drive him

 

Damn, are we driving the same cars???? Are these specs all wrong???? Wouldnt that put it somewhat close to his FD's current level? Even if your FD is closer to 290, the power to weight ratio should still be in your favor.
How good is your brother in law as a driver???
If you want to be sure, get all boltons and if youre still on twins, max them out. Otherwise go right onto a decent size single turbo. lol I know thats what I want!!!

 

I second that. With all bolt-ons, stock twins, 14psi, sans an ignition amp I was able to pull from a 996 twin turbo through a gear and a half. However, after the HKS TP and a good tune the car was much faster and I believe I would have pulled hard.

 

I'm with RotaryFDTT, I barely walked a stock '02 base 996TT from a roll with raceport, E11, intake, exhaust, and some weight reduction.

 

I don't have my old dyno sheet, but as best as I can recall, in my old FD I was doing 337 rwhp with about 300 lb-ft torque. The 996TT will do about the same rwhp, probably a little less, but will have near 400 lb-ft of torque. That's why you need the rolling start.

I know my 993TT with the Turbo S ECU did 322 rwhp compared to its rated 424 hp. That AWD system just sucks the power.

 

A 340 rwhp RX-7 will run with a GT2. A 996 turbo will get beat.

 

Do you have any proof of that? not that i do but those gt2 are fackin fast

 

340hp will walk a 996T easily. I've done it. You guys should stop questioning and listen to the experienced people tell you the facts.

But if you're still not convinced, bring a 996T over to my house. I'll dyno my car for you and then walk the crap outta the Porsche from a roll on Rt 50 any time you like

 

^hehehe I like your thinking!!!

I try my best
