Hi guys, just boosted by b18b block, and have achieved 230whp, However i would like some input into what you guys rekon the stock internals of a b18b is able to handle....
Ive got 550cc injectors and a hondata.... all this on 6psi...

Thanks in advance guys... if there are more details that you need, ask and i will answer ASAP!

A buddy of mine put down 263whp on 9 psi on that same motor... All stock internals...

god damn! thats some GOOD power for that amount of PSI

RSX8600

I wouldn't go more than 10psi with stock internals personally.

boostdc

wow, some good numbers,
any one else?

I would say 10psi daily and not more than 12psi for the track.A B18b can hold 12psi but not daily driving getting the **** kicked out of it.My buddy has been running 10psi daily on stock internals for 2 years now not a single problem.It's all depending on how you drive your car but safely I would go with 10psi daily.

boosted lude

Yes i agree no more than 12psi on stock internals... 12 for the track with race gas maybe... BTW he ran 13.2 on 8psi on street tires not bad for that motor...

there are many people running around w/ 300 whp+ on stock b18b's

properly tuned they will last, mine did.

Wow...that seems so hard to believe. A stock B18b only puts out about 112-120hp to the wheels STOCK!! Damn, you must be using a T-100 turbine or sumthing...!!!!

There are several LS-T's running around at 12+ psi daily driven and making around 300hp with hondata.

P.S. the question was "how much HP can a b18b1 hold"...not how much boost can it hold.

I wouldn't blindly ASSume intake pressure has a goddamn thing to do with the power produced, how it stresses your engine, and how much power your engine can hold, personally.

I would take it a step further and even say we cant measure a "max HP level." Its all relative. Get the right parts, the right EMS and a good tuner...and you'll find out your limit when he tells you

-Nick, who remembers when 240whp was the "max" then 260whp, then 300whp, now there are guys running 320+whp day in day out without any issues.

i run 12psi everyday and beat on it hard real hard. no engine problems yet

NVturbo

HMMMM.....Doesn't this dyno sheet BOLDLY say "Max HP = 263".....Where did you get 298hp from?.....Just wondering??!!!

it says 298 @ 12psi

263 looks to be 10psi

vaporboy12
