Hey guys, new member here although I’ve been reading all your threads for about 2 years now. So as there are many knowledgeable heads on here I have a gen 4 6.0 that I’m building for a turbo street truck and I had ordered a set of srp pro 4032 alloy pistons as it seemed like a good choice at the moment. I’m planning on pushing 15+ psi on this motor I have a forged crank molnar power adder rods main studs etc. I was wondering how fast you guys are going in 1/8th and quarter miles on these pistons. Thanks in advance

I would think someone will chime in suggesting that 2618 pistons would be a lot better for a boosted application. I am just guessing though and I always get the numbers incorrect
best of luck with your build

A lot of guys DO run 2618 pistons on the streets, whether deliberately or out of ignorance (because they seem to be both more available and more heavily promoted). But this isn’t a problem for most folks because these cars are not their primary means of transportation - they are weekend toys and/or track cars rather than daily drivers. For high mile daily driving, 2618 is indeed a bad idea.

I moved to a 2618 motor for a little more juice. Freshend the 4032 motor and put an lsa on top in a street car.
I think you'll be fine. I wouldn't hesitate to run those pistons.

Unfortunately, this means they will likely discontinue 4032. Wiseco did this with 4032. And I have no reason to believe that these guys won’t as well. I guess most people just want the strongest piston available, and probably won’t put lots of miles on their power adder motors. But 4032 was (and still is for the time being) a good choice for those who need extra strength compared to hypereutectic, but want the longevity benefits offered by 4032 vs 2618.

What pistons would be for a 50-70K mileage Maggy/LSA?

I used 4032 in my lsa street car. I have no proof of this but my local engine builder told me they last longer before needing a refresh in a street car. They expand and contract less and require a tigher bore (allegedly).

Yes, the 4032 only needs about .0025-.003 ptw clearance and are quieter. Tight piston to wall means less rocking and better ring seal, it’s really ideal for street- strip use, a max effort motor on the other hand should get 2618 slugs.

Yes, I do too, Ron, I’m using Mahle 4032 in an LS3 with 2cc dome, the rings are the newer 1.0 1.0 2.0, they’re coated with some kind of hard anodize making them dark gray. A little heavier than I like.

If its your only car and you drive it as a true daily drive definitely the 4032...
I have je 2618 and i drive mine everyday but i wont start it up just to go to the shop. I only use when i know that ill get it up to temp fully. I do 600+miles a week, over 14000miles since they went in and no strange noises
