Twin Turbo Typhoon Fpv

they just need to get a hold of the twin-scroll turbo setup.. that sh*t would rock on a GT40 turbo

Umm, explain how a twin scroll set would work on a GT40? The turbo itself must be twin scroll doesnt it? Besides to what advantage would it be using Twin Scroll on the XR6T? It already spools the GT40 instantly and causes way to much wheel spin when power levels rise. All Twin Scroll would do is spool faster make boost quicker and more wheel spin.

Twin Scroll good on 2.0ltr STi's and EVO's that dont have displacment to spool larger turbos...

Nissan GTR's are twin turbo straight six's

What was I thinking last night :lol:

Why would they bother with the cost and complexities of twin turbos when the turbo they have now is good for 600hp.

Single's give more power so I dont know why theyre chasing such an idea

This is not true at all....Depending what motor....

Most others have failed with twin turbo setups and gone back to single turbos.. Even if twin is better than single...Whats make you think FPV can pull it off anyway.....

Two is always better than one. Some of the fastest GTR's in the world run unbelieveably large twin turbo setups after having a big single which didn't provide enough air. For example twin 3037's over something like a single T51R.

I don't think we'll be seeing twins on any of the ford line up mainly due to cost and really I can't see the need.

It wouldn't supprise me.

Aussie's generally hate lag. Hell, the media bags the big chev V8's for a laggy style power delivery. It wouldn't be suprised if with higher boosts (in fpv and XR turbos) it introduces more lag.

It would also make the FPV seem much more diffrent than the XR6T.

Regular Twin turbos is all about reducing mass and therefore reducing lag. While the current turbo could provide 600HP in a aftermarket situation, I don't think Ford would be interested in it. It would wear quicker and be fairly laggy.

With twins they could choose smaller turbos that would spool up quicker and provide less lag yet higher boost.

I think eventually FPV will fit a diffrent turbo better suited to their particular application.

My initial reaction was to agree with Turbo6man; that it wouldn’t be done because of the cost. However, in a premium pricing situation an extra $1k may not be a issue.

When you look towards how you could improve the car there are 3 major areas that they can change (IMHO) to get improvement:

1. ecu – the first attempt was reasonable, but the stalling and overboost problems have been a disaster, and will need to be improved. Of course, the F6 now has the independent cam timing, so that is a major step forward.

2. inlet plumbing – revise a la Nizpro, and design for a turbo car, rather than for a NA with a turbo as an afterthought

3. use a properly matched turbo: The GT3540 is a mismatched turbo, where the compressor is oversized compared with the exhaust. Maybe a pair of GT25/28 or 30s would work much better. From what I read Ford only tried 2 turbos in its R&D/test stages

I’ve owned 1.5, 2, 2.5, 3 and 4 litre turbo cars. Done properly, the 4 litre should not be laggy at all, especially with independent cam timing.

Intentionally or unintentionally (probably more the latter, for cost reasons) lag has been designed into the car, and there is room for substantial improvement.

Twin turbos wouldn’t surprise me, but they need to look at all aspects of the turbo inlet design, not just the turbos. Twin turbos will also give it a much better exhaust manifold result with superior gas flow and spool up over the inefficient current exhaust manifold currently used.

So I think it’s a good idea, and consideration by Ford would not surprise me.

Yeah well I think its the fastest GTR in the world uses a single. Singles will provide more boost than twins, the benefit of twins is you can run 2 smaller ones rather than one huge one and the smaller turbines will spool up faster
