Turbo Dilema, editted: Solved Twin Scroll BW EFR 7670 it is then.

[SCS j1mbo]

Out of interest what turbo's did he use in twin scroll,
The GT30 and 35 dont work correctly in twin scroll as the wheeks wheel is wrong for it and most go for the wrong exhaust housings and most turbo companies dont know the exh housing size is completly diff on it and does not compare to open scroll.

Unfortunately I cannot tell you mark as like I say it was before I was even getting into cosworths!

Its always good to have someone to push it a bit as thats what its all about
Uptill 3 months ago my twinscroll manifold was 3k now with the new company have got it down to 1k so its easier for people to say yes,
I have been running twin scroll kits on the YB of over 5years now so gained lots of exp with them.

Mark

with a bit of help

what you paying for a 550bhp engine build

Blunt and to the point I like your style! So did your engine make over 700hp or not?

Obviously we have no graph to show my 7670 atm, but I have as well as mark has the graphs for my gt35 one and it doesn't hit full boost on the gt35 till 5200rpm the 7670 hits it @4000.... Both twin scroll the gt was a t3 housing (and this turbo was the one I had off ur old man) . This alone should show you how well they work also that the gt series just doesn't like the twin scroll setup. Twinned with the fact when as mark has previouslysaid mine took 3.2s to get from 30-100 iI think mark said?

I didnt make yours rocket power 60 to 100mph in 3rd took 3.7 and a GTX3071 I have just done did the same test in 5.2 both using the same gear and road on the test.
People just cant comprehend how much better a BW turbo and twinscroll make to these cars.

But guys you are comparing a fantastic new twin scroll turbo that is at the top of its game with 2 turbos that are surgetasticly shite I mean full boost at 5200rpm I would think going back to a 20 year old tecnology T34 would be like a breath of fresh air all be it a weak one lol... Just sayin

Adds no more noncy text please

Ile pop up with the gopro you can take me for a spin and will shoot some videos of the boost ect... No funny business tho

Heres a spanner in the works as I have not tested the 7670 on the internal gated housing I am not going to sell this kit only the external gated one I will be selling, Until I have tested it on one of my engines to be happy with it.
