Yeah, I know its nuts. But we’re going to turbo the Screamsicle. (also known as Morpheus..)
For you that aren’t familiar with the car, it’s a 5.7 LS6 engine that has many goodies. The dyno sheet I was given with the car shows 430 rwhp. My dyno showed 362 rwhp. But I’m thinking that was mostly the differences in dynos. Either way, both numbers are thrown around. We’ll go with 362 going forward. We’ll be adding a VS Racing 7875 Turbo with .96ar and V-band connections. With minimum boost I expect to be close to 500rwhp. We’ll use that for AX and track days at least to start. The drag strip is where we’ll eventually turn it up to about 14psi. That will give us approx. 700rwhp and hopefully set a mark to be beat. I go into why and everything else in the video, but really, it’s because I want to… Here’s the intro video for the LS Turbo series on our Budget Outlaws channel. https://youtu.be/6_Mlwf0nHLw |

Great question and I think there is a simple answer. Fast enough is when it breaks, and on the street the more hp, the more wheel spin, or something has to give. So I guess the answer is there is a limit to no limits. LOL Twin Turbo LS you have to get the gearbox from the C8. (IMG:style_emoticons/default/beerchug.gif)

The wide range 4spd means less shifting. 60-100 and maybe even 30-100 times could be done without shifting if I have the gearing right. So that may be where I have my most fun if I'm allowed. (IMG:style_emoticons/default/shades.gif) Can someone confirm my gear ratios? I believe it's a 78 930 box. Diff 4.22 1st 2.25 2nd 1.304 3rd .893 4th .625 |
