Hi,

 

Does anyone have a PHR Street Turbo Kit?

 

Just looking into one myself instead of a boostlogic and was wondering what sort of RWHP you can get from it on Optimax?

Also what sort of fueling system is needed as a minium?

 

Cheers

There can't be that much difference can there cos both kits use the same turbo.....

 

Different manifolds, the Street kit uses a cast mani, Stage 1 and up uses a tubular mani. So there will be quite a large difference in performance. Just because they might use the same turbo does not mean the performance will be the same. ;)

That said...surely you could see 500rwhp on V-Power ???

 

I made around 530 rwhp at 1.5bar (SRR figures) on Optimax and that is with a much larger turbo (T71GTQ) which is rated on the BL site for 720-800rwhp.

 

To be honest I probably could have made a bit more as I did not realise that I made those numbers with a leak on the cold side of the compressor. ;)

Jake what power you getting from you stage 1 at the wheels?

 

Have a look here mate.

 

The thing is not to get too caught up with bhp figures. I'm not aware of anyone running a T60/T61 sized turbo in the UK that is making 500rwhp. Apart from Thor customers of course ;)

No mate, I'm about 80 hp below that.

 

You only make 420ish on all that fancy gear? I'll definitely be sticking with stock twins then - I'm only 50 behind you and I've hardly done anything...and that was measured on a ball-breaker of a dyno, a real ego-killing machine!

Seems it was 427.6 rwhp.

What mods have you got then? And what rwhp and torque?

Where is this ego-killing dyno? It doesn't seem to have hurt yours much :)

Just what i'm debating now, got 350 at the wheels at the moment so is the PHR street kit gonna be worth it??

Sorry, my mistake - my flywheel figure is 50 short of your wheel figure.

 

It was measured at Triton Motorsports in Bournemouth on their DynoDynamics RR, on a day when almost every car got nearly 30 less than they expected (or told their mates at the pub). I just set my expectations sensibly, that way you get pleasantly rather than unpleasantly surprised!
