FP RED dispelling twin scroll myths.
I was thinking today after reading some discussion here on EVOM about the FP Red.
A few months back I started a thread about the use of twin scroll designs in medium-large sized turbo's and how they would perform.
The general feel from the anti-twinscroll advocates was that it restricted top end performance.
I have always been of the opinion that a correctly matched hot side would prevent this from happening and still produce great results.
Other people were saying that twin scroll was only effective on small turbo's ie stock.
Well since the release and success of the FP RED how can this be still true?
The FP RED is starting to make power near to if not above a GT30R and is using the factory twin scroll design. It is even making power close to a 35R with the use of the correct fuel and mods.
What do you think? This is some great results for pro twin scroll, its making good power on such a relatively small turbo. Not really choking the top end much.

I can't remember who the person was but someone on here is running a 35R twin scroll. I watched a video of him smoking a car which had the FP RED.
It looked like he was making good numbers.

Exactly. Also, need I say that, while the FPRed does remarkably well for simply being a retrofitted stock blower, at HP levels approaching what a GT35 is known for commonly producing, the FPRed is maxxed out. Forced Performance would have to regut, and redesign the internals to produce more power, if that is possible.
I am not a big fan of running specific parts on my car "on the edge", for if weren't for a decrease in reliability (perhaps, i could be wrong because afterall, this turbo, the red, might benefit from the general factory design- if any of that is retained interally), but also because I enjoy the of having the ability, and opportunity, to be able to have that large window of tuning possibilities that a GT35 can provide. Granted the spool up time between the two is night and day, but then again, if I strapped a GT35r, or higher, on my IX, it would be accompanied by a stroker kit for sure.

What im trying to say is that it was thought that twin scroll would limit the top end power made by a turbo. For a "small" turbo the FP RED has a very good top end.

Large or small turbo, it makes no difference. They both operate within the same laws of physics. TS is as potentially effective on one as it is on the other.
TS works for 4 cyl engines. This is evident beyond debate. The key to making it work to best effect is matching the appropriately sized housing to the specific application. Unfortunately, there are limitations with T3 turbine housing selection, and this is the primary shortcoming.
And as I've said at least a dozen times before, and as Aby has reiterated here, those who deride TS are those with the least amount of experience with it. Meanwhile, those who have the most experience with it definitely aren't complaining. I know I'm not.
