Just got home from straightline performance 639wh 543trq car actually gained average power everywhere it even flattened the trq curve last dyno was 605 525
Lumberjack cam
IPS stage 2 heads
12.0 comp 93 Oct
Shortened 102 runners 102 tb full 4"intake
Uncatted kooks homemade axle back
Electric water pump br7 plugs 70lb inj
the cats were taken out also and 102TB was added with the custom CIA over the VR intake so its not a true apples to apples but seeing how it changed and smoothed the whole trq curve and the hp curve starts to run away at 4k plus is what tells me it worked i was expecting to loose down low some but it did not that i am pumped about
[QUOTE=double06;1591805437]Any differences doing just regular driving more bucking etc?[/QUOTE
the cam is big and has some of that but not bad at all i think the br7 non projected plugs added to that more than the runners did it deff does not drive like a stock car its got a hinson shifter with mounts monster lt1sc its not for whiners
and i should say this is with 1 deg less timing and a tad richer afr then last time
I have found that once you have timing within range, moving it 2-3 degress does nothing to power output. Only when you are far off MBT, would it be impactful.
If anything, you are better off with less, to protect against bad batch of fuel, hot day, etc...

Great gains! Curious what it would look like revving beyond 7200rpm.
its starting to flaten out maybe with different heads or a mild solid roller i think it would still breath up in that 7200-7400 area or alteast carry the power very well who knows maybe ill find out this winter
When you shorter runners did fast make different runners than the original ones that the intake comes with.....thanks
These are standard runner that come with the intake I just cut and re shaped them since fast will not release the ask runner sets they have been teasing us with for 2 years now
I'm glad it made gains. Thanks for including us in on your project. If you ever drag race it then you'll want to shift it as high as you feel comfy for best performance provided traction, of course.
