SVT raceheader tested

nazthug · Oct 17, 2002

quick results...too tired to talk now

Tested on naders car....vs 4-2-1

4-2-1 made 173whp
SVT header made 167whp

Not exactly sure why...too big? Not tuned for that sort of package? Tuned specifically for the SVT?

Although it was quieter, since its MUCH thicker, and heavier too...u guys better make brackets

Lost a bit more WHP on the red race car so maybe its not the best for all out NA cars...who knows...

I will test it also vs the FC which i already tested, and the new FS 4-1 i will be getting soon....

More to come...

at this NA power, we need a bigger manifold...

well i was telling tuan if svt only pushed out 145 on a dyno how could you get some huge gains with the svt header naz you have 166 your above the svt right now ehehe why go lower wait till they make an svt perfomance header then think about switching ehehehe your still awsome bro

Dev · Oct 17, 2002

But doesn't Nader have a ZX3???

I know that they fit the Z but why test a SVT race header on the Z and then compare the 2???

Not starting **** just asking a question.

mY sHoE · Oct 17, 2002

yah yah thanx dev just what i was wondering. yo dev sup dawg what have you been doing bro i have not heard for you for decades now ehehe. hey dev maybe you can answer my thread about the torque pressure.

<hr /></blockquote>They tested the SVT race header on the zx3. Why would they expect gains on it compared to a header that was made specifically for the Z? Is that easier to understand?

thats my dawg yah now thats what im talking about go devon go devon its your birthday go head

uhm...come on dev...R U SLEEPING?

Have you missed the whole SVT header craze and how its the bomb digity header?

So they decided to try and test it on a focus...the first people to do so just for the hell of it, and see what it does, so people know what to expect, when selecting hte SVT header over a race header designed specifically for the car, like the FS or FC header...

Thats all...come on guys...think...please.

Everyone wanted to know how it does against a race header, since its big, its got cool bends and all

ALthough the cool thing about it is that it quiets the engine down, makes it sound smoother...guess its the design and thickness

mY sHoE · Oct 17, 2002

And there it is folks question answered war over eheheheh the end ....

Dev · Oct 17, 2002

Thanks for the answer guys. Naz I know about the craze but I kinda figured that they SVT race header would be too much.

FocallyDistorted · Oct 17, 2002

So what about putting say a FC race header on an SVT, will it work?

I think that it would choke the svt.

Do the math man, i know even you can add...

SVT makes about 145whp

Nader is making 173whp
I am making 166whp

HOW IS THE header we are using, which gives more hp than the SVT, choke the SVT?

And how can the svt header be good for the svt and be too big on our cars??

Do you see what im getting at? Im a bit surprised at your math man...u must be sleeping...i dont blame u i guesss

nazthug · Oct 17, 2002

BUT as far as the results...im not sure what to say or think...they are just tests and results...

It is what it is...Im not sure why the SVT lost power....maybe the design is specific to how the svt acts....i know it cant be too big...

Because it lost EVEN more power on the red race car, that uses 2" header, 4-1....so go figure...

The funny thing is that it lost torque too...youd think the desing was for torque...hmm...

On the other hand..the yellowbird hit 150ft/lb of torque

again, i think the first NA car to hit 150ft/lb of torque at the wheel....

I may be seeing a set of stage 3's in the very near future,,,,they peaked out at 6600rpm too..kinda weird, but we concluded that the only thing holding it back is the INTAKE MANIFOLD

NO matter what cams, exhuast, head people run, everyones numbers tapper off at about 6500-6600rpm

mY sHoE · Oct 17, 2002

ok the issues concerning the switch of a fc header to a svt gains yah. why because its called vice versa but dev bro is right just might flood it with more than it could handle .but maybe not ehehe .i think there would be great gains shshshs. svt just has polished and ported wider heads cams ehehe not saying anything pistons differ and thats all. that gives it those gains nothing naz and nader aint already got.

Dev · Oct 17, 2002

Okay man. I was referring to the SVT raceheader and the FC race header on an SVT. That's what I meant. I guess I should have been clearer.

Uriah · Oct 17, 2002

I would be interested to see what re-tuning the cam gears would do with the SVT header.

brewfo · Oct 17, 2002

This sucks!

Is this with the full SVT header, cat, flexpipe or with just the header and FC cat elimination pipe? Can we see the dyno graph?

But, as Naz said, the SVT header on the SVT that has 145whp, LOOSES power on a ZX3 with 170whp.

which would MEAN that the FC race header IS BETTER, FLOWS MORE, then the SVT header.

I mean, it's pretty clear.

One thing I want to know, did you tune the cam gears with the SVT header on there? There might be some power to gain from tunning the cam gears at differenct settings then the FC race.
