Hey guys, i know its not "SVT" but its the Teksid DOHC!!
Finally Got the Mark VIII Dyno Tuned at Logan Motorsports. I got a SCT Xcalibrator2 and had Logan see what they could improve on..
So, as it was, before hooking up the xcal, i asked if they would do a dyno pull just as i had it, when they did, the air to fuel was soo lean that he didnt feel like it would be a safe pull so he stopped it at around 4000 RPM. For some numbers, the a/f ratio was at a little over 16:1. for those of you who dont know, it should be, depending on the tune, around 13:1 ish...
I was reallly suprised.!!
After the tuning, it ended up putting down 239RWHP and 245RWTQ. It was still making power all the way to 6000rpm(where the dyno stopped) he said at 6500rpm it makes 243-248rwhp..It was about 80 degrees in the shop. I had the shift points raised, Shifts Firmed up! Which was a HUGE difference. Cooling fans come on around 180 now. along with some other things.
Heres a graph of one of the pulls. As you can see, the torque curve is nice and flat, So for everyone who had questions about running a short runner cobra intake, You don't Loose the low end .. Just goes to show, unless someone has done it, then nobody really knows for sure.(nobody has dyno'd a mark viii with short runner cobra manifold.) i had soooo many people tell me that it would be a dog down low even with the 4.10's, grant it that i am still running the imrc's..
Overall i am REALLY impressed with the numbers considering on their dyno, (which they told me early on reads a little low), that the gen 2 marks were running from 205rwhp to 212rwhp.. so to be conservative, i gained about 30 wheel horsepower from the mods in my sig.. Very impressed. heres a video of after the tune 0-85..

and lets not forget the before the tune video i posted. you dont need a timer to see that it is way slower here!

anyone got a stopwatch? i would like to see how my 0-60 and 0-80 changed between the two videos!
Comments please. Be honest!
