I'd think 5 across the boost areas would be fine and still conservative. You do have small bores, so it has a big impact.
Ideally, someone with a turbo'd 3.0 using J&S Safeguard could provide solid values. |
How did you do an entire turbo conversion in a few weeks? That is amazing to me.

I would estimate around 16 hours actual working time to complete it. |

I can't say this enough, it's easy to wire one up. The planning takes the longest. |

Nice build, just keep a eye on your injector duty cycle with e85 and 60lb injectors. I'm running the flex fuel sensor with ms3x and it works very well.

Dyno #s are in 402hp 361 tq
I will post the chart when I get home. Pretty happy with the results... |
Running E85?
Nice numbers!! |
Yessir

Air/fuel ratio was in the mid 11s. Their gauge was not working correctly, so they did not put the air/fuel info on the sheet. Kind of wish they put RPM instead of Speed... Maybe i can get another printout next time i am in the area. |

Here is another dyno pull that looks a little cleaner, not sure why the other one is so jumpy. |
Damn! nice build! That has to feel scary on the street. Is that still on a 915 gearbox? Did you shift into 5th at the end or something???

Nice result. I am sure its a blast to drive.
Did you datalog your run from the laptop? btw, you asked a question previously about timing. Yes, I also think this is conservative. though you are running high static compression so it probably works well. That is not a problem. However, Please do yourself a favor and scale your timing (and presumably fuel) tables where you will use them. Your timing curve shows peak pressure at 250kPa indicting 1.5bar boost pressure. I think you are only running up to 0.8bar boost. If so, you are not getting anywhere close to the top three rows of timing. This is just wasted resolution for you. Your max row should be somewhere around 180kPa maybe slightly higher depending on actual readout numbers from your MAP sensor. Then rescale the load values to fill in the gaps. You also need to scale your rpm bins. Your last column jumps from 5400 to 7500 rpm. I doubt you are spinning so fast. Notice that dip in your curve from 105 to 120 mph? That is your car wanting more timing. You can see the output pick up as you transition from 14 to 17 deg timing coming closer to the last cell. You can back calculate your rpm from the speed assuming you know which gear you were in. I would guess 4th based on the speed. This will help you determine where you need to adjust timing. carry on. |
Thanks for the feedback, I did not think to datalog any of my runs(would have been helpful) I have modified my timing table since then, I will see if i can post an updated table. but yeah, i see the jump from 5400 to 7500, that cant be good. I still have up to 250Kpa, so i guess i should probably dial that back a bit. I have a weird hesitation around 3k RPMs, and that happens to be an area where the timing jumps pretty drastically. This was just a tune that i conjured up from the autotune function, and the Spark table was modified from someone else's 3.0 build. I am thinking one day i will spend the $ to have someone custom tune the car.

Hot damn! Those are some big numbers! E85 is where it's at for sure.
Congrats on the #'s! |
Still the stock 915. We ran it all the way up to redline, that was most likely the fuel cut.
The car feels crazy fast in 3rd and 4th gear on the interstate. I really didn't know what to expect with this bastardized motor, but it seems to be pretty happy with the turbo. If i were not running E85, i would be really scared to pop this engine with the 9.5:1 compression ratio. Quote:
