How many bhp with these specs ?

How many bhp with these specs ?
Was wondering :
YB standard bloc with standard cr
bd10
T35 0.63
Siemens 55lb
Large intercooler
30psi
Would say around 350bhp, but how much torque ?

Also forgot to say antilag 2 stages (mild and agressive). Would the bd10 be a better option than the standard ones ? Not interested in high-end power tho. More by large-band torque.

Antilag wont effect the peak power.

so with 30 psi i would imagine you to be getting high 300? low 400?

Yes well I am more interested by torque or having a more stable engine, so would prefer to have strong mid 350bhp rather than having to think about "what will break when I'll push that pedal to the floor". Main aim is large torque range.

Leave the Exhaust cam as it is, i'd opt for a BD14 IMO, live mapped with a T35.63 and 30 psi, i'd image 380ish with similar FT.LB...
You've siad you're not botheres with top end so much, so why not try a .48 hosing, you'll still get 350+ BUT it'll be nice and punchy, makes for a great road car..
My old 3dr made 363 bhp and 360 ft.lb with this setup..
There's not much that will trouble you then..

Yes, a 0.55 would be nice, but "problem" is I got a 0.63 T35 maram shafted to I better use it with mild antilag and when I want extra response, go for wild antilag. Would a head-work improve response too or would it be too much money spent for low improvement ?

You'd need to watch your transmission with anything upto 400bhp aswell, 4wd tend to break..

Yes, no launching etc and it'll be fine..

ive used bd10s for months on a t3 and t34 i found the car more agressive past 4.500 rpm. I changed back to standard cams boost peaked at 4000 rpm rather than 4600rpm on the bd10s the car had more midrange and was smoother altogether this was on a t34.63 to end with. So my opinion is standard cams for your spec and a .55 housing would be a lttile less laggy but loose a little yop end

Yes I am considering .55 option too at the moment. Still, what is the difference in peak boost between the .55 and the .63 housing ? I mean with a good mapping you can get quite a lower lag with .63. Heard 3500rpm is possible. But if the .55 can peak at less than 3000rpm I could be interested.

Not sure why turbo died,used Silkolene oil,allways let it cool down after thrashin
Few T34 cars that had been mapped to 35psi at MSD had no probs,including Stu's own car

I cant really add to any of the above, but I can reinforce it.
I am running pretty similar setup. Mild head improvement combined with T34 0.63 on Siemens 55c inj combined with big intercooler etc etc.
Car is on std cams and mapped by our good friend Stu at MSD.
Cant give you an official power figure, but I can say that Steves (Cossie4i) was dynoed at about 360 odd bhp, and his bum dyno reckoned mine was pacier.
I have always guessed it to be at the 380+ mark.
