    I installed a 2021 angle drive into a GEN 1 2019 car last night using the 2021 drive shaft and belt and it is direct replacement. Speed matched perfect did not get a MIL on the dash. the 2020+ angle drives had a complete overhaul on the design bigger casting with more ribs. I wish I would have noticed this 1 year ago. Seems Polaris intends to use these parts in the future to replace old units once they burn through the previous generations. The 2020+ has 1" larger ring and the ratio is 2.8:1 with a 35T output sprocket the previous 2015-2019 was 2.25 to 1 with 39T output sprocket. The sprocket change is what makes up for the difference in the drive ratio and is why you will need to run the shorter belt if you convert. Parts needed. 727-809-3256 is the best way to get ahold of me.

    Thank you! I Started it on August 9th and we Rolled into Vegas the day we where SUPPOSED to be there at 9PM on Sunday night (6 hours late) made it from Florida in 41 hours and that was after getting hassled from the DMV for an hour and a half in Tallahassee.

    Car guys get this build! IMO its a Slingshot still just one withOUT a traction issue! The quad kit has fixed the traction problem and am able to put this 525hp to the ground. I'm in search of traction loss again, The LSA build should be fun. See ya'll much later
    Haters are my marketing team! :thumbsup:

    Thanks Travis!!!!! the LS3 in the orange car is GM performance 19301360 525hp 483FPT and will be tuned on the dyno at the Tuning school where I have been training/learning GM we should be able to squeeze some more HP out of this beast! 700 club lol SMH.... next build should be more then that. This 525hp SS hooks up with the Bullet Speed quad kit. It is ready for the LSA build



    I will post some videos to my @bulletconcepts on the instagram and on our FB page follow and like

    This thing is nasty! I think it would roast any other SS ever built in every catagory, 60ft, 1/8mile 1/4 mile top speed and braking and I have built/driven some fast SS's! I would jump in it and drive it back to Canada right now but Dyno day is next friday and I have to finish breaking in this engine and trans and change the fluids. Next one on the books will be LSA with a built 4L60E for SEMA 2018 and will be in the American Force Wheels booth.. Same spot as last year! MSSGA! American Dreamin!

    Did you get the warm and fuzzy feeling or not really?

    Bullet Speed built the quad kit, Roof, Hood vent, and hand brake for 3P and 3P came up with the overall look and wheel choice, The wheels are sick! They are putting a blown 5.0 coyote motor in it now 850hp

    A couple other things about the dyno numbers that you saw, you should have a higher drivetrain loss with the 4 wheel conversion than the stock 3 wheel setup also, so do not expect to make the same power as the 3 wheel Slingshots at comparable flow rates.


    Also, that engine that you posted in your pictures looks like a used engine, please make sure to replace all of the plastic guides for the timing chain when you build that one up. Those plastic guides will get brittle and break on higher mileage engines. I am guessing with your level of detail it is something that you would do anyway, but just want to make sure since some people will not replace them when building their engines and it will become a problem later.

    our AFR was below 8.0 when we came into boost and dropped off the map..... should have been 12.0 so we where losing power based on that. We are also thinking we might need to move some O2 bungs around due to turbulence that Noel pointed out and also proved on a test drive. I have to get with Noel and see about getting another ECM flashed based on the dyno results. But FF is gonna tweak the bung locations and I thing dyno pulls will be necessary. Thank you for the information. btw Private message me I have a customer that wants to go supercharged.


    Thanks for the info Dave

    Greetings! I would like to pull some info from this forum about a couple motors I am building for our Slingshot, the engines are LE5 2.4 Ecotec, I have built a few V8's NA Ford/Chev this is my first Turbo build but I am in good hands with the Fab Factory. I would like to push 450 WHP out of this and as you can see I have motors to break if needed! The best dyno pull we have seen from this stock motor was 279whp 283wtq with a super fat tune on the ECM from Bob in cali (his first attempt) I know I am going to install ARP head bolts and stick with the stock crank, With some type of forged piston/Rods, Most likely gonna go with a standalone Haltech only because I feel like our hands are tied when on the dyno.


    couple thoughts
    counterbalance delete?
    Head?
    Cams?
    VVT or delete?
    Pistons?
    Ring Gap?


    Lets see what you guys have to say?
