    I dont know.. but you will have to let us know.
    depends on what manifold pressure there is internally for the air to want to find another way out via external gate...

    I hope not but i'm sure CTS have done there home work??

    I'll keep you posted as i know you have the same cast manifold in your workshop and sure you will want to try it some day.

    I would be happy with 400+ The GTX3076r is rated at 630bhp i think i would have to fit large injectors if i want more

    The mass airflow spec of a GT3076 from what I have seen so far is approx 52lb/min... Garrett say that you get approx 9.5-10.5 bhp per lb/min of flow... so that would suggest the GT3076 is good for something between 494bhp and 546bhp depending on the spec...

    The 0.63 hotside will limit high end power though but will make the car more drivable

    Ok, that appears to be in the region of 64lb/min then looking at the compressor map I just found... so 608bhp to 640bhp then... should be interesting :)

    Hotside will ultimately kill off top end power but should drive nice especially with the 2.1 :thumbsup:

    Be good to see what this is capable of..

    400-500 I think it will be more than enough for my needs

    I hope it will be a nice drive too

    Im busy building up my S3 with that manifold and GT30. I only got the manifold from CTS as i had the rest of the hardware (turbo/wg etc).

    Did you buy the kit with the downpipe included? I was tempted to go for their downpipe but buying it seperately was going to cost nearly double what it will to have a custom one made over here.

    Great thread!

    Total flow and boost dependant of course... that power is assuming quite a lot of boost..

    Lower boost pressure will achieve the 400 to 500bhp range Andrew is after...

    I know
    Still would have been nicer to see how the GTX stacks up against the EFR turbo's

    I haven't seen any test results for the EFR Turbo yet, It will be a good turbo for sure but i don't want to be one of them people that gets the first ones and something bad happens.

    efr look interesting and likely excellent, however at a price, and Engineered For Racing are aimed at racers

    Thats what i thought

    If it went wrong it would be very expensive to repair and how many people in the uk would repair it?

    At least with the GT and GTX range we all know are reliable and not as much to repair, many places in the uk and repair or overhaul/service them.

    EFR turbo is destined for my racecar during this year, so i can see how it compares... significant reworking of my installation... EFR are large units physically.

    Do they come as a external gate turbo? all the ones i've seen are internal gated?

    With the turbo power range from 400-500bhp i'm now thinking that the 630cc injectors may be on there limit at 450bhp and thinking about going to Siemens 80lb (870cc) High-Impedance Fuel Injectors? so i might be able to see 500bhp?

    Just a small update as some may know i got my GTX3076r and kit from CTS in Canada, also placed a order for some 870cc injectors, supertech valve springs and titanium retainers.

    Did a little dummy build of the manifold, looks like i may have to mill the head to clear the down pipe but no biggy

    I'll update a little more later on

    I just meant as opposed to the 2.7TT conversion or turbo'd R32 engine, but I couldn't say 1.8T as yours ain't 1.8!
