That's a really nice, flat curve.
A little later boost onset than a GT3071/64 but holds the peak for a bit longer.
Awesome job....you may want to richen it up a bit between 4250 and 5250 just for safety's sake, but you're probably fine through the winter.

|GenuineSaab||Since my dyno is equipped with dual widebands I have been playing lots with this before and after thing. At light load obviously the signals will lag quite a bit but once the load (airflow) comes up they are always the same, just the time alignment is offset. Remember the cat can only work near stoic..|

would there be any advantage to running it down to 12:1 and putting in more timing? i would think that might help the power hold a tad longer since i doubt there is a bottle neck in the system, unless the exhaust wheel is really that small.

Ims, I kept the viggen stock for 3 days I was very impressed with it in stock form. I did put in t5 cams and the 6cm2 turbine housing from a 9k aero and with the light Woessner pistons and the lightly lightened stock flywheel, the car is very fast. I am surprised! Its an 02 model and they were rated at 230bhp and they have leaned out the fuelling map to get that extra power and it goes very well indeed.
I have now tune it for stg 1 and set up the knock counters in the sid function so I can see the knocking counts on each cylinder and then reduced the timing so I only get about 1 knock count per pull. It was about 3-4 knock counts per pull in stock form and made about 1140 airmass. I have it making about 1220 airmass now and raised the first and second gear torque limits. Its a fairly quick car now.
Next will be a stg 3-4 with the ets ic and 3" JT exhaust. The last step will be stg 5 e-85 flex fuel.

|Moosepuck||Thanks everyone... I'm very happy with the way she drives..... I don't think I want anything bigger that would cut down on my low end... I am helping someone else with a Holset VGT install on his 9-5, if that works out on his, it might just be the best of low and top end...should be interesting......|

Very nice indeed!
John, what have you done to your new viggen?

|wasaaabi||hey lowbudget...i dont' think i ever had the chance to get back to ya. sorry. but yeah, still got it. how u doin?|

|lowbudgethero||that is such a flat power band over 300hp from 4250 to 7K|
|12-01-2009 03:55 PM|
And I like how thorough it is, with boost and AFR. You should add it to the thread in the proof section!

nice run moose!
my car's on the rack as we speak. .64 exh housing going in, with the 60lb injectors. and a new JZW tune....wish me luck. nice stickers BTW. i'll keep y'all posted. =)

Remember that is at the tailpipe, wide band right after turbo shows 12.5/1
|12-01-2009 07:47 AM|
13:1 af? tad lean for my blood.
i bet you could go dow to aout 12:1 and put more timing in.
boost holds solid though....how much more do you see on the road?
|12-01-2009 07:11 AM|
Thought I'd share here as well......
Here it is, looks like the AFR is pretty good, I see a couple more PSI on the road, but I'm pretty pleased overall with the nice, wide powerband.....
Thanks to JZW for all his help, (let me know if you see any other changes you want to make)......
