Hi,
it is safe to run 12-15psi with oem rods in a b16 engine?
 
Depends what turbo, on a t25 probably so, on a gt30 probably not lol
 
I read a lot from people who don't recommend more the 1psi, but those peaople didn't try more eather. Just a few cases where they tried and had no problem with, 12, 15psi

I love these questions...

The most accurate answer I can give is.... I dunno...

Power output and rpm limit may get you better advice though...
 
As stated above running 12-15 psi on a small t25 turbo will not have the same flow volume as a running 12-15psi thought a T3/T4 turbo. Theres a much higher chance of melting a piston before shooting a rod, saying that it all depends on air/fuel set up.
 
I currently have 8,7 psi and got 245whp. I know a stock b16 can handle much more than 245whp, but it can handle more boost?
 
Its the power i.e. cylinder pressure you need to be concerned about. Do you honestly think the pressure inside the cylinder on the power stroke is the same amount as boost pressure ? ;)

I must have said this a million and one times on this forum but you still see questions like ''can I run 9 psi on a stock this and that''

If you want an answer to the op's original question the stock sleeves will break long before the rods break or the ringlands break.

Boost is not what breaks things, poor tunes or pure power/ cylinder pressure is what breaks things.

Exactly , excellent point. There is a lot more to boosting than Bar and engine size. A lot of people dont realise just how much has to be considered when boosting car. Not directing that at the OP.
 
Hi we run upto 6/8psi safely on most b series depending on compression. That is using a td04 or td05 (Subaru).After 3 years of running a forced motor on 8psi it was stripped to have forged internals and everything was still within perfect tolerance
So yes you can do it but dont go greedy on boost.
 
Mines running 10psi, 340bhp and is scarely quick so why the hell you need to run 15, unless your drag racing is beyond me tbh....

believe me, i did A LOT of search before asking. But sometine is not easy find answers depending on the search string.
