How Much BOOST!!!!!!!!!
 

How much boost can i run on a hks 51 r before my engine cant handel it anymore.........? what mods do i neeed to run 25 psi...........

On my HKS T51R-KAI setup i ran 17-18psi on pump gas

as for 25psi..you need some serious dowel pins cause thats some serious strain on the motor...the housings could start pulling away from each other

Dude, you have been listening to all those tuners out there who make up that kinda bullshit to excuse their poor tuning, Extra dowels are like 3mm seals. Totally un-needed unless you plan on detontation. With 2mm seals in a standard engine detonation will blow the apex seal, with tougher apex seals you then break the next weakest link, which is cracking the endplate, added dowels dispence the load meaning you dont crack the end plate apon bad detonation with tougher apex seals. with added dowels and tougher seals, bad detonation will lead to caving in the face of the rotor. Both Cris and Peter will tell you the exact same thing. after all it is from them that i learnt that.

If I understand HWO's post correctly he's saying that tuning is the key issue.

YES, you can run 40psi and make 900 odd HP from your 13B provided you have enough fuel on tap and your seals are clearanced right. extra dowels are a detonation band aid thing.
