drive to dyno instead of trailering with the mindset that if it cant survive an hour drive it dont need to be on the dyno.
30 miles in, it started running bad and really rich. Wide band on driver side but what I find after a couple dyno pulls trying to find source was a burnt plug wire boot. Brand new firecore with high heat boot,I let lay on header and didnt know it. Rick is taking care of it but I also paid to add titanium sleeves to them.
also on driver side was 1 plug that looked dry vs rhe rest that was wet. I'm changing out the injectors for some I was gonna put in anyway. Fic1000 ,

I will have running Wednesday when I get home with repaired wires and new injectors

 

Figured I'd do an update. I got my plug wires back from Firecore and put them on, put new tr6 plugs in and running good. There is still some issues like header bolts backing out and my exhaust pushed off yesterday. Fixed that and went out driving and tuning yesterday. I have ltft's dialed in to within 2% so I'm happy with that.
wot is close as well. Command 12.73 air fuel and is actually around 12.3 with my meth spraying. That is there for safety and when street cruising but when I go to track I'll turn that off. Which would put me around the commanded air fuel .
. I run boostane mixed at .25/gallon of gas which is around 97 octane on the chart for boostane.

I moved my tq arm down two holes on front mount and that made a huge difference in the way the car bytes. The mad is ported and feels awsome, just seems done by 7200 rpm so the same guy who ported it will also cut 2" out the runner and reinstall the bell mouths on ends of runners. Really helps these motors rpm more which is why I went solid roller to begin with. That will come once my gremlins are all sorted out.
also had a charging issue that was fighting me. New alternator went on and then I pulled the small wire from alternator to the ecm out of the connector. Had to fix that too. But it's coming along.
My vacuum pump is pulling lots of oil with these valve covers. I have to make a baffle at bottom as it's right over a rocker and its slinging oil up to the vacuum pump. This testing was with no belt on pump and hose disconnected from valve cover. I covered the valve cover port with rag and zip ties to let it breathe to atmosphere for now. No oil coming out.
. So at 20deg timing ,meth on and 12.3 air fuel, its moving a lot of air in the data log. More than my ls3 head combo ever did. Just need to get it right and go back and try it on dyno and the track.

 

Car is driving good. Tune is dialed in pretty good until I can do another cold start idle log. Once warmed up it's really close.
. Still only 20 degrees of timing until I either dyno or run at the track to see what it wants.

I tried getting a draggy 60 to 130 pull but had to hit the brakes and pull went to 129. Damn 1mph shy of goal.
a dog ran across the road.

car is strong though, I hate to speculate but the buttometer says its stronger than ls3 head set up

 

Good deal Chad. Keep us posted.

 

Will. Do Scott. Im on a boat until Tuesday so nothing but time to imagine im driving it😂

 

went to the track Friday night. Trying to dial it in there is tough but the best pass was at 22 degrees of timing and spraying my meth kit(spraying -22below windshield cleaner) .
10.35 @131.86 1.44 60ft
That was footbrake.
Turned meth off and slowed to 10.36@131.65
added 2degree timing and left on transbrake at 3800 and went a 10.35@131.5 but new best 60ft 1.42

so it dont want the timing without the meth and it showed as it loses mph even though the da was getting better.

best pass was 350 above I believe got down to 200 on my last pass.

probably switch to e85 soon and cut the runners in the intake 2" to get more rpm .

 

that thing is getting it! Mine is down for the count now. 3 dead cylinders. Time for more powa for me too!

 

sent to much boost? Come back stronger. Win win😁

 

That 60' is killer and the car is definitely making some steam @ 131 mph. What is your race weight now?

 

hasn't changed. The msd intake is at the porter getting the runners cut 2" for more rpm.
. A member here is sending me a Sniper for ls7 to try, I will dyno with it, draggy test and go to the track before the cut runner msd goes back on

 

Race weight 3841

 

Holy cow, definitely making good power bro!

 

hopefully I find some more with the intake swapping but after that it's all going in to using all I have. No more hp mods

 

I'm pretty much close to that point with my Camaro build too. It'll be losing weight now. I'm curious to see how much you pick up up top with the shorter runners.

 

being a solid roller build ,the stock length msd just isnt taking advantage of the rpm capability and flow of these heads.
after seeing that my 60ft only marginally improved with the msd over the old heads with a point less compression and short runner sniper I figure going shorter will be better for me.

had I changed cams with the heads to work with the msd ,we could get it to rpm more. My cam needs shorter runners to do so

 

Update on cutting the runners. BRENTON done a great job with them. He cut them down to 6.75" long . Car is running with the intake back on, I do have a coolant leak on a steam port on passenger rear of head. I'll have to lower the k member down and see if I can reach it or pull intake back off.
anyone needs any port work done,I highly recommend Iron mask airflow innovation. Very meticulous with his work and puts a lot of time in doing it right.

 

Old ls3 head combination

Old ls3 head combination vs new mast ls7 heads with a modified MSD sr intake with some tire spin and looser converter

Top is final pull bottom is first pull on ls7 heads aet up. Also tuning in e70 fuel



dyno done at Engine power systems by Geoff Skinner.

 

So the new Mast top end didn't increase quarter mile performance (mph) that much? I am really surprised.

Weight didn't change between the two packages right?

 

it wasnt as much as I expected honestly. The best ever with ls3 heads was 10.29 at 131.8 in -800 Da

went 1 time with ported msd but stock length runners and mast top end. Went 3 back to back 10.35 passes at 131.6 in plus 350 da.

My converter really needs to be able to rpm more than 7200 so I had runners cut down ,now peaks at 7100 and pulls all the way to 7800 maybe more. So next time track is open I'll see if that improves anything.

car was 3841 with half tank of fuel how I run it

 

I dont have good data at track for the short runner Msd yet other than a spinning track visit . I did make more mph from 1/8 to 1/4 mile so I feel it is helping.
I just bought some 28x9 pro bracket radials and mounted on some 15x8" weld pro stars. The combination of wheel and tire will drop 15lbs off each side compared to my forgestar d5 15x10 /295x55x15 Mickey Thompson ss radials. And should hook better as well.
I got a set of 15x3.5 weld pro stars to match the rears and with a regular street radial from an old Volkswagen bug they dropped 10lbs per side compared to my 17x4.5 d5 fronts and Mickey Thompson sr radials.
50lbs of unsprung rotating weight off the car should also help.
I also just swapped to a 4.56 gear from 4.10 gears. First drive was an hour ago and nice and quiet surprisingly for a Richmond 4.56

I would go to state Capitol tomorrow but track wont be good and I need to break the gears in more. I dont like changing ro much at once but lighter wheels and tires are a given and with the data I got on the dyno and the track last outing, I need more gear to take advantage of pulling to 8000 rpm. I will test with my msd short runner intake and then swap to a sniper intake that i'm gonna try. Aaron on here sent to me. I forget how to type his screen name on here but thanks Aaron, hopefully we get some good data on that thing
