I was wondering how much boost a pinned block can handle? I have JE 9.0:1 compression pistons, and eagle rods so my internals are all good. I will be using the new smc duel, 450cc injectors and a msd inline pump. Let my know what you guys think. It's on a b18b by the way. thanks

 

i just ordered my smc dual. do you like it or hate it? ever had problems with too much compueter advance??

 

Anyone want to give a number that the stock sleeves on a posted block can handle?

 

I am going to go with 298.

 

lord...ok, you probably will never go over 25psi or so if I had to bet...just try it out and see...as long as you have no hair line cracks in the sleeves and you have had it properly re-centerlined after having it pinned, it should hold just fine for whatever you want as long as the rotating assembly is properly balanced.

 

my friend daniel had a b18a, ran about 19 pounds and bite dust. All tuning was done by DSR on a Dynojet with Motec A/F, and then bam, the sleeves ate it. that run was a 11.8 run. i posted a pic of the sleeves somewhere on this site.

 

but the question remains...did he do this with his sleeves pinned or just normal (straight from the honda engine assembly plant?)...the guy wants to know what he can run pinned versus stock after all and you didn't specify...

 

One important thing to remember, even though it is pinned, they are still stock cylinder walls that don't move as much. Just be cautious, start out low, watch your vitals, then slowly move up... EVERY motor is different, what worked on one ls block, may not work on a different ls block
