HKS T04-R -->> Bullseye power Turbo, what size to go for

[Callaway Motorsport]

Hi guys,

 

After seeing other people getting Bullseye turbo's, it finally gave me the bump i needed.

 

I have been thinking about one of these since September of last year, when i spoke to one of the american guys who has a S472 on his with race cover. Not sure which in/ exducer sizes he has but i'm not comparing that anyway.

 

It would be to replace my current HKS T04-R setup with .96 A/r

and the goal would be to get a more reliable/ durable turbo (ball bearing),

make some more power (700-800 WHP mark max) without maxing the turbos potential. But at the same time not loose the good spool and response i get from the current setup.

 

Altough i have been following Jamie's progress with his billet turbo which is now giving interestingly high power,

I have read and seen more info on the bullseye turbos recently with good and better results against other turbo manufacturers.

 

I was wondering whether any of you experience guys could help me a little with your own experiences as to what turbo to go for, what size to upgrade to etc when going to a Bullseye setup, as they have many choices not only in compressor sizes, but also in the different housings etc.

 

It would be choosing the easier way when just ordering a T72/78 just to make more power. But as said above, I would just like to hear some tips/ comments from others what there experience and or advice would be.

 

Thanks

 

 

PS: dyno sheet below, car is on stock fuel at the moment but will be a Stage 2 PHR kit going on to support the power...

Be aware that the current status due to stock fuel is that its running @ 1.2 Bar when it can go to 1.6 (as per HKS spec)

For 700-800rwhp you are going to need a fairly large turbo, id keep an eye on what Paul wiffins dyno sheet is like with the Bullseye S368.
