  • 4.1L stroker

    This is just a reground 3.8 crank right? AKA offset stroker. Why is it 2000$? I know it comes with rods, but still. I understand its a lot of work to make, but you can get a completly new forged LS1 stroker crank for that much.

    So whos going to start the first GP?

    There are alot of machine shops that can do an offset ground crank for our motors. Check with yours to see if they can get you what you need. Or pay ZZP or whomever for theirs, since they did alot of R&D on their kit and have it ready to go, no guess work.

      Just noticed today on their web site they reduced the price down on this 4.1 kit. Just an FYI. :D

          1500 is a lot better price than 2000...it will probably spark more interest.
          And on their site they said it could handle 8 pounds of boost if nto a little more...so it would have you covered...it seems pretty cool.

            You can go much higher than 8psi on the STOCK crank. I wouldn't buy this junk. You could make the same HP with the 3.8

              true you can go higher than 8psi on the stock but you will reach higher hp faster with a stroked motor plus i would think a turbo would spool up quicker with more gas being burned (hence more heat) than a stock engine. i agree it would be nice to get a forged crank but for those of us looking into no more than 7-8psi this is something to look into now.

                It's not worth it. The reworked crank splits in half at merely 450 crank HP. That's not much when talking forced induction, and or nitrous. The stock crank can handle over 600 HP at the crank in bursts. You do the math. The stock crank is better when left alone.

                  I don't think that the 4.1 kit deserves so much ragging. It is now another option for those that want to increase performance. My hats off to those guys for putting the effort forth to try other things for the better of the community. Quite of few of you are putting this thing down but it might be the perfect alternative to those that don't want to worry about the headaches of FI.

                  I am not saying that I am going to do this mod just wanted to add a alternative view to the stroker haters....LOL.

                    I don't hate the stroker idea, I just think the should have used a custom billet crank, which would have been much stronger. In essence making the stroker a viable mod for everyone, whether N/A, FI, or Nitrous.

                      i deffinately agree with that. im planning on getting this after i get my turbo done and then getting a custom crank built. then ill come on here and sell the reworked crank probably.

                        I'll be honest, this is something I REALLY want!

                        I WANT more N/A power!!!

                        This would keep me VERY content.

                        BUT, I WILL NOT sacrafice my nitrous capabilities.

                        If they come out with a MUCH stronger crank I would buy it in a HEART BEAT!

                        Old dyno for me was 315 rwhp and 380 rwtq.

                          I know some of the nitrous cars are close, but has anyone on this board EVER dynoed over 375rwhp? 450 crank hp is a hell of a lot of power for a V6. Also, has anyone ever broken their stock crank?

                          What I want to know is how this effects the cyclic stress on the crank. If you run 300rwhp how long before it breaks? I know there is some way to figure it out. I have got to start paying attention in these engineering classes.

                            Does anyone have a good idea at what track time would be with this kit? My guess would be in the low 14's, considering it's near LT1 power numbers, with 240 RWHP.

                              The stroker kit itself wont give you 240...thats with some other mods as well if I'm understanding correctly...but thats still good. 240 N/A is quite an accomplishment for a V6
