our race car made 395 to the wheels on a stock gsr block at 20 psi, eventaully one of the valves gave away though. :shy:
1: You’re talking about a race car that doesn’t see daily driving, and sees something along the lines of 3 or 4, 11 second Qtr mile passes a month?
2: The B18c block is a substantially different motor compared to the B18a. I.e., oil jets, rod/stroke ratio, factory block girdle, etc…
UCSlugRacerX : I think everybody’s right saying what are the weak points in the B18 block, and you really seems to be trying to have the last word on that subjet…
A fact is that without serious work a 3-400 whp block has less change to last longer than a sleeved block. Pushing beyond the stock rev limits is also something bad to do. Even though some people do it with success, others has less chance and sweep the engine pieces left on the floor…
Where I meant to go with my posts is to discuss the tensil strength of the Al blocks—such as the block threads for the head studs, and possible solutions for that. Have you ever tapped in headstud threads on a B-series block? It’s very very soft, in comparison to iron blocks.
Great job completely avoiding my question regarding our conflicting technical points. I don’t care about insignificant shit like who has the last word. You can always start up another thead. (If you want an endless flame war, go find Armed Ferret:rant: )
And obviously you know all about me, and this makes complete sense, considering me and a good buddy built my B20vtec 2 weeks before I drove the engine for 10 to 12 hours straight for 7 consecutive days across the country (around 3,000 miles) cruising at 75-85 mph, @ 4500 RPM’s with a '93 GSR YS1 short gear ratio tranny.
Your broad generalizations such as, “thats what i thought , sleeve fails when the pistons hit the walls if you pass the 6500 rpm redline,” has not even remotely been justified using technical evidence. Under what bore/stroke ratio, and stroke-to-rod ratio? 1.49:1? 1.7:1? Under what piston-to-wall clearances? Under what thermal conditions? etc… My point is that there are so many variables. But regardless of that, this is where I intended the discussion to go. Not about insignificant shit regarding who has the last word, or your insults about how all of my experiences involves destroying “B serie block.”
hehe the ‘distroying b serie block experience’ was not an insult at all !! And for the technicality i assum you know about everything, and i know some also, and that has already been discussed before in various other threads.
The internet is actually a serious source of conflict since you never hear the way things are said, and if you knew me, you would never have though i was insulting anyone.
And since i own a B18a engine containing LS crank and rods, i’ll ever go beyond 6800rpm because i know what it may cause in terms of a long or even short period wear.
it made closer to 11 10sec passes
