My brothers B8/BP-T.

Well here it is my brothers engine he has been working on for fester. B8 block, BP head, and BPT turbo set up. We have a legit BPT engine but its for truckstiva later in the future, anyways here ya go:

[David88]

Very nice. What are the plans for it?

[mikemounlio]

looks good

[Damkid]

That engine would look good in my aspire

[Gforcefd]

Nice engine.

A couple questions. I thought the B8 Block with BP head raised compression? I probably have this backwards. If I do have it right, wouldn't that be a issue for the boost?

That engine will look super sexy in a red or black, or well any festiva

[91_festy_Gl]

Im not sure about the compression thing but it is getting dropped into a red and black festiva lol. I think my brother said it will lower the compression, I dont know?

[daniel_cogar]

im in class so real fast lol..... it lowers compression meaning with that head on a b8 block i can run more boost and more fuel. -dan

[sasquatch]

but the b8 crank isnt as strong as the bp crank... its lighter and will rev quicker but i dont know how long it will hold up to boost... and i cant remember if it is true but i think the pistons and rods are a bit weaker too...

right but with a vj23 charger on it it will be ok as a dd... i was just saying that about the bigger charger and fuel. i am just putting this one together to drive regularly and my TruckStiva the all out performance..... seems like i read somewhere this engine will hold 23lbs? before complete disaster. dont trust my menory on that the lol.... @ 15lbs 200whp with the vj23

[hofficergrover]

I don't know if 23lbs is right.
Had a friend that ran a pass on 24lbs and blew the bottom end right out on to the ground at the end of the track. It was a stock motor too

oops I did mean 23lbs as the limit as in not safe lol ... sry-dan

it dosnt matter what psi your running... you could run 25 psi on a tiny turbo and make X amount of power but if you got a higher flowing turbo (bigger) and ran 10 psi i bet you that you would make more power.... it may not come on as quick but it would be a better set up bay far....

right as far as air volume goes with that set up... but, a engine internals can only hold that certain amount of pressure. stock, untill you go forged pistons and rods. I think that you and I are on different pages lol. but were both correct to a extent.

I have seen stock block DSM's run 500 horse on stock rods, crank, and HG but with a good tune, but if it were me Id run 12 to 15 LBS of boost for a stock DD. IMO the B8 has enough power as it is so with this DOHC set up and 12 to 15 psi you should be happy without blowing the engine, and if it does you can give me that head for my B8 N/A build comming soon lol!

People arent understanding that this isnt a all out build, this is just something fun to drop in the car and play with. No way is that little turbo charger going to blow the bottom end on 15 psi.

Not comparing DSM to BP-T or BPT but stating that anything is possible.

No way is that little turbo charger going to blow the bottom end on 15 psi.

You can blow the bottom end out on most cars with crappy tuning at around 8 without proper internals or craptastic tuning.

15 PSI is relative to the amount of volume in the piping and engine. A larger turbine will push the same amount of PSI at a lower RPM but turbine size itself doesnt actually change the amount of air that PSI is relative to.

And actually a smaller turbine not properly tuned to the motor and PSI you are planning on operating at could indeed cause troubles. A larger turbine flowing more air at lower rpm will do so much cooler than a smaller turbine flowing the same amount of air at much higher rpm will run significantly hotter and increase engine, exhaust and intake temps dramatically.

Now of course a stock issue turbocharger for a BPT will do 15psi no problem since its properly tuned to the motor volume and RPM powerband, but i would reccomend if you havent already done your research to read up on turbine maps and how to properly match a turbine and the "sweet spot" to the appropriate RPM and PSI you want to ideally run.

Ask me how i learned all this the hard way some day BP #1 went out at 15PSI and BP#2 unfortunately suffered from a boost spike caused by a crappy ebay wastegate and shot a rod out the bottom at about 25psi
