Hustler, trade me your 6 speed for my 1.8L and 5 speed combo!
Nice numbers! I want a ride! |

Nice numbers! I want a ride! You can get a ride, hopefully at the track. I can't wait to rape in this thing. Suspension and brakes are still impressive too. Its a package deal. |
Torque doesn't hold too well after 5k. But still, solid numbers, especially for a dyno-dynamics. Your timing table is wild. I so gotta get me some 8.5:1 compression pistons. That's a good build and good tune for track duty. For damn sure.

fuck your 93 octane, fuck your timing map, fuck your 8.5:1 motor, fuck you
fuck youuuuuuu No likey the 2860 spool? What RPM were you making, say, 12 psi at? It is hard to tell from that dyno plot picture. |
would be schweet to see the datalog to go along with that pull
|
a lot of timing, not a lot of fuel, at least not much resolution in the fuel map. what is your REQ FUEL?
You're doing well, but I think you can be doing much better. :) |

LOL. No kidding that timing map in boost is nuts. I would have been pinging like a mofo with my 9.5:1 motor. And that is with 93 octane.

I bet that car is slow. We should have a drag race in reverse gear.
I expect nothing less than FTD at Hallett! Unless Matt goes...... |
you two should race in drag:giggle:

Way to go Hustler! The grass is always greener ... even though you are doubting your choice in turbo, it seems to me a great choice for what you want your car to be which of course is track slut and annihilator of snobby fags in expensive cars.
Everything will be just fine my friend. |
No doubt a 2560 would spool sooner (mine does 14psi at around 3300rpm now on the street at part throttle), but your 28 will not see much below 4k on track anyway and will run cooler at that. So you win on the track unless you forget to down shift :)
|
So.. more boost?
Seriousy though, congrats huster! I'm glad you stopped being a bitch and are happy about the car now. |
OMFG Now i know i been away to long hustler has a turbo :magna: needs to come back and haze him bad lol
GJ man |

Magna, it was about time! We miss you :giggle::magna: You went away for so long that hustler had time to complete his build! :) |
fix your spool fool!

req fuel is 5.7 and i have a new walbro 255. I need to learn more about tuning, but I don't know where else to find the answers or theory to make this turbo spool-up faster and to keep the torque high after it spools. I don't know what to do now. |
It looks like his afrs are around 11.5 to 12.0 during spool. I have found running 13.5 14.1 during spoolup increases it alot. Also you need the most ve% at torque peak. After that you should tapper off ve% since your required fuel per cycle is less. That is why you are getting richer and richer on the big end and losing torque. That is unless you want that for safety.
I personally tune for good afr's then add timing. 12.0 at your boost level. One thing that adding fuel does is delay the beginning of the burn thus it is the same thing as retarding timing. I have found that running the correct afr and less timing makes more power than running rich and more timing. Very good baseline tuning. Let me know if I explained it properly i'm not a good explainer. |
