This is going to be a little long but want to give all the info....current setup is basically
TFS 11r heads (190 58cc)
R intake
60lbers
Ultra gold 1.6 rockers
Ba2400
Upr boostpipe
Strim (high output...stock pulley)
Crane hi 6
Crane coil
Ngk plugs (3/4" reach per TFS rec and 1 step colder than stock)
Msd 8mm plugs
Blew a headgasket on my old setup 2yrs ago...stock heads and gt40 tubular intake...took me until this past winter to get it back together with the current setup.
Took it to a dynotune to have it dialed in...i have a 4 bank SCT chip...i believe he wrote code with moates quarterhorse...
Well he starts getting cold starts amd idle dialed in etc...it went quicker than usual he says and starts pulling power out of it...starts a lower rpm pull...makes adjustments...more rpm...more adjustments etc....gets to the 4th pull or so and tragedy strikes....my waterpump gasket blows.... (i didnt realize the gasket was most likely compromised when i blew the headgasket since i overpressurized the cooling system)...trailered it home...got my new gasket on and drove it around for a few weeks before taking it back to make sure i had no more leaks etc...3 weeks later (aug 28rd) i drove it back (no trailer available this time)...then i find out he didnt know i was coming back in that day his receptionist never mentioned to him and it was his first day back after a week vacation and he was on his own at the shop this week (so seemed a little rushed but still personable etc)
Straps it in...asks abt how it was running and i said man it was running great...good on cold and warm starts...crisp throttle response etc...he said ok great ill just work on pulling more power...
Adds some timing (went to 17* i think)pulls 491rwhp @5600rpm i think...ups to 18* pulls 514rwhp...he says wow if the block would hold this setup could pull 600rwhp bc i still have 3 more degrees i could throw at it but he doesnt like to tune a stock block over 500rwhp at most... (he does alot of ford tuning from what i heard and read abt him etc)
He makes a final pull after dropping the timing back down and the boost falls right off...he said the supercharger was "heat soaked" from all the pulls? And that it would take awhile to cool off so he locked it in at the last good tune at 17* which was 491rwhp...this is my first build and first time on a dyno but i didnt like that the car wasnt re-pulled after that...is heatsoaking normal?
He says he threw in some safety precautions such as made the tune a little rich...pulled timing when intake temps get over a certain setpoint etc...said if it was a race car he would risk it more but wants to keep it together as long as possible (as do i lol)....
I take it and start driving home and already notice it isnt nearly as responsive nor crisp as it was before this second tune...felt too rich...drive it home...not overly impressed (tune was $650 btw)
Fast foward to last couple weeks..usually when i back out and pull into the garage i go nice and slow and ease out the clutch and let it pull me in or out respectively...now it just about stalls or stalls...
Tonight i go to take my wife for a cruise and let it warm up in the garage a few minutes...back it out...and i hear what sounded like a small buzz or click from either my ignition box (crane hi 6 mounted on pside tunnel) or my ecu...shut it off and restart it(no more noise)..car just turns over...try again and give it gas...it struggles to start but starts...idles down and stays running...blip the throttle...sounded clean and crisp no hesitation...
Shut it off and start it again..cranks fires up and on its way down to idle rpm range shuts right off or has a few struggles to stay alive and then shuts off...again with throttle it will get started then stay running...my thoughts are its too rich and my plugs are carboned up? Or my box is going bad?
All my gauges look good...fuel pressure...oil press...vac...etc..
Sorry for the long story...i appreciate your thoughts...
