but the difference is the torque and where it makes the power. yes, the S makes decent peak HP. however it doesn't actually see that number till your running smack into the redline. the turbo will see more power, sooner. i put my money on the turbo given equal driving skills.

 

not to mention, my cab makes similar power to a turbo. doesn't get much heavier than my car with 19's and a blower. i've raced an S with software, intake, and exhaust. in the same run i've also raced a regular 997. slaughtered both of them from 50mph roll ons and i don't make nearly the torque of the turbo.

 

i've already proven that the suncoast headers make power on the NA cars. didn't you see my dyno?

 

and i proved the headers add zero....

 

D dog I think when used in conjunction with other mods you might pick up 1 or two HP hence your car being supercharged but on a N/A car I just dont see it.

 

I think what a lot of you guys are referring to are the whole effect and sound of the car. I dont buy that you will pick any more than a little better increased throttle response.

 

Not really true. Stock turbos dyno in the 370 to 390 rwhp and 380 to to 390 rw torque. HP gives your top speed but torque wins races. A stock 996 TT has 100lbs of torque more than than a 997s. Sorry but there is no chance on this one.

 

agreed and proven with my car

 

I'll agree to disagree with you and P997S being that I've tested these headers firsthand. And I tested it alone without the addition of several other mods added at the same time.

Something is obviously amiss with either his tuner or dyno's.

The hp obtained from the headers on my car is not a culmination of mods. The reason I tested those headers is because I saw the same results on NA cars. Cars that I had seen in person. I figured if they got those kind of results, I would get as good or better with the SC. Well, I ended up with the exact same results, not better or worse. I was skeptical when Suncoast showed me the dynos and quoted the numbers. That's why we worked out a deal where I would test them and if they didn't produce, I would return them. They worked, plain and simple. Yes, there is a slight low end tip, but that's what happens with exhaust tuning. It's just a good design. They spent a lot of time engineering and testing to get the end result. I'm speaking from experience here, not what I read in a magazine or got quoted from a salesperson.

I have no idea what is going on with P997's car. I wish he had done the mods individually and dyno'd each one. Something is not right. The flash, intake, exhaust, headers, etc.. should get get around 20 rw peak HP. I wouldn't expect much more than that. The fact that he got zero says something isn't right. EVO thought enough of these headers to start selling them, that should tell you something....

 

Ddog,
Are the headers that suncoast sells the same as evo? Is there any change in the sound with the new headers?

 

I agree with you with the fact that P997S claims he got 0 difference. He says this out loud everywhere. Even with a muffler swap I would expect him to gain or lose a little. With all the mods he has getting 0 is just does not sound logical to me. There should be a change even if it is for a decrease.

P997S: Buddy you are the only one I saw in all the forums I frequent that gets 0 difference. As I said I do not expect power gains as advertised, you may even lose some with some designs but there should be a difference. Can you clarify that issue for me and for some other members as well.

 

listen up everyone..i did all mods and did before and after dynos with a member of suncoast present and assisitng - same day, same dyno..the gains were ZERO...i then went to a different dyno a few days later and got the same results..it is what it is..i have no reason to lie..deputydog - u live near me - any time u wanna meet up and check for yourself...im hesitant to redyno - why pay good money for somehting im sure will show the same result..i have the dyno sheets...

im just trying to help save other people money..you cant improve on a NA porsche engine without supercharger or $17k x51 package - period..nuff said..if you dont want to believe me - go spend the $3k on intake, headers and flash...

here are the numbers guys

1st pull - very cold car - sat for 3hrs before first dyno
hp=312 tq = 260
2 pull - hp = 302 tq = 252

after mods - same day, same dyno
best pull - hp=304 tq = 251

next day - different dyno
1st pull hp=305 tq= 251
2nd pull = hp = 311 tq = 250
3rd pull- slightly lower judging by graph - numbers were cut off the end of the page

so i say zero based on 312 and 311..or zero based on 302 and 304 - ok +2

interpret as you will

 

yes, last i heard is that evo is now rebranding and selling the suncoast headers.

the car is noisier and the pitch of the exhaust is a little higher. i have to admit, i like the sound better with just mufflers, but it's still pretty cool with the headers too.

 

there has be something wrong. maybe there was a hiccup with the flash and is causing the computer to slightly retard timing. maybe the maf got soiled when they did the intake? plugs slightly fouled? who know's? to have the mods you have with zero gain sends up a red flag. have you called EVO directly? ask for mike or nate.

there has to be an explanation for this as you should see some small gains. they probably don't result in more than a tenth of a second in your zero to 60, but a slight HP gain should be there. i personally wouldn't spend $3k to get 20 horsepower, but i don't doubt that you can get that sort of hp from those mods. i went for the blower because it's the best bang for the buck with modding our cars. like i said before, i've seen impressive dyno runs with those headers on other people's NA 996's.

your dyno on the day the mods were done shows a loss after the mods. that alone would get me asking questions. what does Gordon at suncoast say?

 

I know with my Gemballa exhaust, headers and chip upgrade my butt dyno say nothing. Gemballa I think claims 25 hp. Just my 2 cents but heck my speed limit is 55 here.
