                                            Got the refreshed Aaron Ginn Racing Transmissions 4L80 back in today, went out for a test drive and got a block away before the driver's side front brake line blew 😭
We limped it back to the shop to try and fix it tonight so we can still make the test and tune at Kearney Raceway Park tomorrow...I really want to see what this E85 stuff is all about with some party pulleys 😎 
42 tooth is the smallest 8MM pulley they make, and we're currently running a 47 top and 49 bottom (4% overdriven) so that would put us at 16.5% overdriven if we just changed the top pulley 👀
We also got a 51 tooth and 54 tooth for more combinations up to 28.5% overdrive!! 🤯 that would be the upper limit of how fast we can spin The Blower Shop 10-71 with the rev limit we have on the engine and we'll definitely need more fuel injector/pump and different fuel (methanol 🫣) to run that much boost
