Firstly WHY is 400 bhp so neccesary to you?? are you number chasing??
I,d go for a T34.48/55 i had a T34.48 on my old 3dr, Greys live map and tbh it was imo the PERFECT lag free, punchy setup going, live mapped peaking @ 32psi holding 28psi believe me, they,ll not be TOO much on the road that should bother you.....
Don,t get caught up in number chasing...................

but like i said i'm not looking for 400+ i'm just looking for around 400.
dont get me wrong the car is nice now when it comes on boost and a lot of fun

to be honest i think it is number chasing why change the car from standard in the first place ? it made good power out the box , but then we all get caught up with wanting that little bit more .

My T38 Saff was horrid how it delivered power, now my GT30 Evo was completely different again...
I,d personally opt for a T34.48 everytime now on my cossie, just a great road conversion imo..
Other people will agree/dis-agree, that,s life...........Lol..

if you want mid way power range id deffo go t34.55 or the smaller gt30 option.

I guess aswell guys it,s all about traction issues too..
I mena you look @ some of the Evos running GT30s, there 30-130 times are mid 11s alot of them because of no wheel spin etc...
Planting your foot in a rwd cossie with 450-500 bhp with similar torque in 2nd/3rd is going to be FUN TO SAY THE LEAST...

it seems there are many options lol there is pros and cons everywhere and mainly comes down to personal choice which im still bloody confused about just been on ggr's web site and how would you describe this turbo ? GGR 287 Stage 2 Unit - Larger compressor and turbine assemblies with 360° thrust bearing .
is that a t34.55 ?

Ok so you bolt this t34 .48 and some 55s on your fresh motor (and other bits). You are NEARLY at 400hp (at the flywheel).
So what does that translate to in performance numbers on a 2wd? 0-60 in 3.6 seconds? 170mph I assume.

My 3dr is running a Turbo Technics stage 2 T3 with 360 Thrust bearing, very punchy turbo ,BUT will die and explode @ around 320-330bhp max, it,s running 27psi peak on the live map, again it,s right on it,s LIMIT at this but that,s how i wanted the car, yes suicidle i know, BUT IF and when it does die i,ll go for a T34.48...

from my experience a genuine 170 mph will be a long drawn out affair with a t34 160 mph and it will be on its knees.

With the right rubber and alignment it's a big help.
Crap road tires and some saggy old beam and you will not be doing much under 5. Zero'd back end, 6 degree beam, some semi slick road tires. Actually tire size (diameter) would be quite critical.

On a ford speedo easily, I was quoting GPS figures
It did 170mph in less than a mile at RAF Woodbridge when we ran it there, and it did 150mph in half a mile, so I reckon 1.5 miles and it would nail 180 pretty easily as it was still pulling hard on the 170mph run

There are too many police or too many corners here. We don't have any airfields to go play at. No real chance at the big top speed runs unless I drive down to Bonneville.
Maybe I need MSD to sponsor me on a Bonneville speed run.
