Vortech Tuning, HP/TQ with 600cc Injectors
I'm in the process of Tuning My Vortech Setup once again.......
Top Log Setup
2.87, 32/28 cog, Walbro, 440cc DW's, 6/1 FMU, 4 x 12 x 24 core intercooler, headers, full exhaust, no cats, ect. ( keep in mind that in this log I rolled on the throttle, was not at WOT to about 5000rpm)
Attached Log Setup
2.87, 34/28 cog, Walbro, 600cc DW's, 3/1 FMU, 4 x 12 x 24 core intercooler, headers, full exhaust, no cats, ect.
Still a little Rich yet from about 4000rpm/5.5psi. Looks like I've gained so far a solid 20-30 WHP, and 20-30 Ft/lbs WTQ with 40 Ft/lbs WTQ in some areas. With 3/4 to 1-1/2 Pounds of Boost from 5000 up. With a much Broader HP/TQ curve. I still think their is a little More, will Lean it up a bit and see if I gain any.
Note: I would not go to a 2.87, 34/28 setup without a huge intercooler.

I have an LM1, the LM2 is a little different, I'm not sure what....
You can Log with the LM2, you need to download the LogWorks3 Software, its Free. but you will only get AFR's, if you add the Aux box they work together and then you can log AFR's, Rpm, Boost, EGT's, IDC, ect.....
logs look like mine. I kinda wish I woulda put more 1/4 mile times on my G before I took it apart. Only 2 passes since the local track is 1/8th.
thats why i always tell people to keep pulleying down til you make a good trq curve. It can be done with a Vortech setup easily to match any turbo kit on a stock block.

Looks good, 4100-4400ish you could lean that out a lil. you are in vacuum and less the 3lbs of boost but your air fuels are high 11's low 12's. you trim that area in throttle response will feel alot better when entering into boost..
what are you recommending for a/f under 3psi vince?
^^^ not lean it out the same overall, more so have the taper a lil better....for instance at 4220 RPM he is still in vacuum and his air fuels are 11.85. lil richer then they need to be, I usually have it tapering from 13.0 under vacuum to 12.5ish around 3-4 psi and the slower tapering richer as boost builds and torque continues to climb...

Vince, you are looking at my old Tune with 440cc's. I put it up for to compare. Look at the Attached File MAP 11 in Post #2. Pretty much the whole map is still too Rich in open loop. I still making changes to lean it out. what are you suggestions for AFR's.
Thanks
Thanks
^^^ Pretty much what strdum1 said, except maybe with the 2.87 pulley I would run it richer above 7 psi like 11.7ish. Also those "estimated" dyno numbers are prob off by about 15%...

i assume this is because of the building nature of a s/c.
would you still run leaner on the rise of a turbo setup?
^^^ yea def....actually if you look at the fuel curve of a lot of factory turbo cars the have really lean spool. The GTR at about 6lbs of boost air fuels were at 13:1ish from factory, and when we richened it up it greatly effected power and torque in spool.
That's just one example but a lot of cars respond the same way. Once you start doing bigger turbos you cant get away with that cause at the same boost level you might be flowing twice the air....so its all relative...
