Quick question for those of you with MKII 996 gt3's... is 430 whp a legit claim for a highly modified one OR are that kind of numbers even possible?

 

It depends what modifications are done to it. Is it still a 3.6? If so, it is not possible.

 

Thats what I thought... I didn't think that kind of numbers were possible without upping displacement or camshafts if you keep it normally aspirated... someone (from a local shop none the less) is trying to tell me that an extra 50 hp in the gt3 is possible with only a K&N filter, full exhaust setup, and a powerchip ECU... of course I knew that wouldn't be possible, but I wanted to know if the 430 claim could be possible... how much does a cup car with its modifications put out?

 

I have those same mods in my 996 GT3. It does not have 430whp. I am supposed to get it dynoed this week and will post the results.

 

One of you is mentioning whp, and the other 50 more hp. 430whp is a lot more than 50 more, because 380 is at the flywheel. If that makes any sense.

 

Right. You wrote what I was thinking.

It's difficult to get a lot more out of this motor. Luis, I'm interested to see your numbers after your dyno.

 

I have done 372 rwhp with my 996 GT3. Only mods for that are bmc filter and europipe exhaust. Dyno was on the Mustang @ AWE Tuning....Great shop.

 

well the original discussion I had was about 430 rwhp, and I disputed that fact with only know how hard it is to get 50 plus hp out of my 986 S's 3.2 let alone a 3.6 from the GT3... a local shop chimed in saying that with the mentioned above mod's that 50 horsepower was easily possible. Do they EVEN? make a K&N intake for a GT3?

And I think Luis was being a little sarcastic

 

Most 996 GT3's dyno closer to 400-405 crank hp.

 

I was?

 

I have the Manthey 410 kit and thats ECU power chip Over size headers racing cats and mufflers so thats 410 at the crank. 450 at the wheels is probably not possible without forced incduction.

 

um I can't read...


Thanks guys!

 

Didn't know they dynod so high, cool!

I didn't think he was being sarcastic???

Confused now.

 

IMO, of all of the 996 GT3 "Kit or bolt on combinations" The Manthey 410 is one of the best engineered ways to extract more useable hp and torque out of this NA motor.
Point: 50 or so plus hp for just a couple of bolt ons is hard to believe..

 

actually it's probably that Boxster/GT3 and you guys are discounting how many hp all those stickers add.
