is there one available??
i know abbott has one for the T5 but i havent heard about one for the T7

That sounds more like what we call in the tech industry an ID10T error. Seafoam is a great product. Just need to use it correctly.iGOTaSAABstory4u said:ive heard bad things about it.
i hear that ppl did that and caused damage to the engine.

I understand that...Adrian W said:That's because it isn't horsepower which would determine the useful limit. It's the air's velocity in the pipe which determines the restriction, and that is represented by RPM, and, to a lesser extent, VE.
Most of the time, with a turbo car, your power increases come from more boost. More boost increases the density of the air, but not its volume, so the velocity through the pipe remains the same.
I'm not suprised Nick saw a reduction in power either. T7 uses the MAF for most calculations, but the pressure sensor in that pipe is used for a few. If you increase the diameter of the pipe, the reduction in Bernoulli Effect will cause all the readings to be somewhat inaccurate, so those few calculations will be thrown off a bit.
I get that but... He says there is a restriction on the pressure side to. That is fixed w/ more boost. So that says to me by eliminating the restriction on the pressure side you would get more power w/ the same boost levels. Do I have my sides mixed-up?saabkid37 said:yeah your missing the fact that the delivery pipe isnt on the suction side of the turbo, its air being pushed to the tb by the turbo. the main restriction is air filter to compressor until yu hit 400bhp
Here we go your lazyness. :lol:saabkid37 said:post up the paragraph, ive read it but dont feel like finding it right now lol.
I remember Nick talking about this and what I remember him saying is the stock plastic delivery pipe did better because it did not heat soak as much as the metal larger delivery pipe. From what I gathered, he said he did lose hp, but he lost if because he felt the plastic was better at not heat-soaking and the metal pipe heat-soaked easier and caused the reduction in power.pade900 said:At above 400hp the plastic stock delivery pipe shows no restriction.
And Nick at GenuineSaab pointed out that he had a decrease in power with a bigger delivery pipe on his Viggen at below 300hp.
So the delivery pipe is far from the first mod you should do, unless looks is all one is after:roll:
Yes, I'm aware of that.Adrian W said:That's because it isn't horsepower which would determine the useful limit. It's the air's velocity in the pipe which determines the restriction, and that is represented by RPM, and, to a lesser extent, VE.

So a good sized delivery pipe w/ ceramic coating plus a little re-route to keep it further away from the engine could do wonders!John Z Williams said:I remember Nick talking about this and what I remember him saying is the stock plastic delivery pipe did better because it did not heat soak as much as the metal larger delivery pipe.

Air density is huge and if the air is warmer, its expaned and thinner and less dense and the power levels will be less. Heat soak is the big enemy of ng900's, 9-3's and the like with the small engine bays and massive under-hood temps. I did notice my 9000 aero is much less prone to heat soak with the same power levels and I believe much of this is due to the size of the engine bay and the location of the delivery pipe that is farther away from the engine...

In my case 375whp with 1.3bar of boost with the plastic T7 pipe.liketheword said:I get that but... He says there is a restriction on the pressure side to. That is fixed w/ more boost. So that says to me by eliminating the restriction on the pressure side you would get more power w/ the same boost levels. Do I have my sides mixed-up?
liketheword said:I understand that...
But, Nick says: "We can overcome restriction on the pressure side by upping the boost. On the turbo inlet it is suction, which dramatically alters the compressor efficiency for the worse. This problem is easily solved with our new version MAF to Compressor pipe." So he clearly states there is a restriction on the pressure side which would include the delivery pipe.
I must be missing something in the reasoning here...
dont really get what you mean, but as stated above. I do not have problems with heat soak in my car.John Z Williams said:Yea, heat soak is good for power....
