Anyone using this in their setup? Do you run a tighter piston to wall clearance? Is it good for street application? Any information would be great.

Any research I have done on the topic says, so no where near worth it for a DD. There are WAY cheaper ways to get more power, this is more reserved for capped engine class vehicles that need to squeeze everybit of power out of what they have.



Sorry if that doesn't answer your question or if you were just curious about it.....

Just get the rods rifle drilled,to get more oil around the wrist pins and pistons

A lot of turbo cars come from the factory with piston oil squirters. If your oil pump is up to the challenge, there is little downside to cooling your pistons this way. It CAN slightly rob horse power (not enough to notice) by creating more oil mist in the crank case but it can also keep your pistons in tact under more extreme conditions. For a moderate build in an engine not equipped with oil squirters from the factory, I don't think I'd worry about it though.



For reference, we do run oil squirters in our 1100 hp, 2.0L Mitsubishi drag engine. We do have a block built without squirters however so if we get a chance to run that engine this year, I can report back if we notice any difference.

Does the Beta have the same oil galley running along the bottom that the 4G63 has?

I'm not sure, I'll have to look into it. I would imagine the 4B11 in the Evo has squirters so my thought is that the provisions are at least there in the Hyundai version.

Beta block does not have provisions for oil squirters. You would have to rig up something completely custom and not worth it.

So there is no oil galley near the bottom of the cylinders then?

There is an oil galley/line cast into the beta1/beta2 block, but you'd be drilling into a cast iron block, tapping it, then threading in the oil squirters. We've got no way to VERIFY that the galley that's there isn't also shared with some other oil passage...and if you tap that, what are you diverting oil from? What are the adverse effects of diverting the needed oil flow/pressure from that galley to your squirters? On top of that, you've got no way to tell how well they squirt @ various oil pressures(how are you gonna test?), if they are aimed right, etc..etc..etc. And if one falls out, you better have an oil pressure gauge and always keep one eye on it and be ready to shut down fast!



For a street driven car. NO, not needed, not worth the effort/hassle/risks.

If you were building a 600+ HP drag/race car, maybe.

Thank you Random, that helped out quite a bit.

I plan to do a full analysis on a spare block in a few weeks, and see what options there are for them.



Cast iron isn't that hard to tap anyways, just need to know how to work it right.
