who have ran or tested an engine with a t34 .55 ?

somebody has some dyno results to show?

what kind of injectors and cams should be associated ?

This is my mates graph, the engine spec iirc is :

SCS Built 400/420
7.6:1 C/R
Ported Cylinder head
BD16 inlet
Stock exhaust
T34.55
Light blues

It wouldn't hold the boost on the rollers due to it being run in 3rd on close gearing but its give you a rough idea of what to expect

Mine made 371.7bhp & 351lb/ft on a Dyno Dynamics RR

Peak boost was only 1.7bar @ 4200rpm dropping to 1.4bar @ the limiter 6700rpm, it holds a bit more boost on the road.

Spec is mild head porting, standard cams, 4x4 inlet manifold, 2wd exhaust manifold, light blues (400s), T34.55, comp 7.8.1

I was going to add that on the day the car ran about 1.7-1.8 bar which goes along with your figures Steve

On the road it peaks at 2.2 bar falling to around 1.8-1.9 so I don't think the engine is far off the power figures it made when it was built 7 years ago.

I wished mine peaked a bit higher, i get about 1.8bar max and 1.5bar held.
But mine is on a crap chip, soon to be changed

I had a t34/55 on a standard engine runing 21 psi and it made 290 ATW at AVA and was a very nice car to drive.

Good turbos IMO

Would like to crack 380bhp, but not that worried. After more midrange to be honest.

Hows the tina coming on ?????

i have the same spec as steve (cossie4i) apart from mine is standard c/r and mine has been live mapped at NMS u do notice more power at the higher rpm (i had a .48 before) it is slighly more laggy but this might be down to the mapping as it did have turbo surge when u was mapping it,mines set at 30psi spike 27psi through mid range tailling to 23psi at 7k

didnt beachs old saph do 379bhp? that was live mapped by karl and was running t34.55 on light blues

i suppose that it's good choice for road ....
