Hi, I am new to this forum and I have a couple of problems with my sycone right now.
even though I could be opushing more boost, it is tunned for 20
psi ant it is all I am running for now.
My first problem involves a lot of blow by. it has to oil catch can connected to each head cover and the one connected to the passengers side is also connected to the intake. if I disconnect any of these, bkue smoke comes out of the valve cover hole where the breather goes, I guess the turbo sucks it in through the intake when connected and blows it out the exhaust. I thing this might be a bad ring but the funny thing is that sometimes it smokes a lot out the exhaust, and sometimes, it does not smoke at all. Oil pressure, temp etc etc are fine.
My second problem is that, out of 7 races (per say). the drivers side manifold gets red glowing hot. I have not a clue of what this is, sometimes it does it, sometimes it doesnt. the first time it did this, was when I found out the torque converter was lose but I fixed that and is still doing it.
And the third one is, that if is a hot day and I don't full trhotle on it for a list 3 sec. so the methanol kicks in, when I try to launch it, it takes years to boost up or sometimes it won't even go over 6 psi deppending on how hot it is.
I figure all this could be related to tunnig because is tunned for a much colder weather but I wanna see what you guys think about this.
here are some of the mods in my truck: (thank you)
”4.3 Bowtie V-6 90 degree block”
This block has siamesed cylinder bores, priority main oiling, 8620 steel main caps, the three center mains are splayed 20 degrees on the outer bolts.
2" OD cam bearing at all four locations. Deck height is 9.025" with a maximum recommended bore is 4.150".
The block is set with wet sump oiling.
cylinder bores and heads have been O-RINGED
Heads are studded with ARP fasteners.
block is bore 60 over with JE forged pistons (compression is 8-to-1)
Eagle H-Beam rods
Billet crank
Clevite H series main and rod bearings
Total seal rings
ARP fasteners thought out
CRANE CAMS Billet timing set
Cam Motions Custom Grind Cam
Melling oil pump
Pro/Race harmonic damper all steel construction
Lunati Hydraulic Roller Lifters with vertical link bar
Competition Cams Hi-Tech Stainless Rocker Arms Rocker Arms, Stud Mount, Full Roller, Stainless Steel, 1.5 Ratio, 7/ 16 in. stud
McCoy Motor sports stage 3 heads they flow @ 28” intake 278 and exhaust 201
2.05 intake valve 1.67 exhaust titanium retainers
Custom Aluminum Fabricated Valve covers
Arizona Speed and Marine twin 58-mm throttle body (polished)
Upper and Lower intake “pro” ported

Tony De Quick Air-to Air Intercooler
Polished intercooler 2-1/2-inch tubing
Snows Boost Cooler Stage-2 with a 7-quart reservoir, Waste gate Solenoid Upgrade, Reverse Flow
Check Valve
Duel stage Turbo X electronic boost controller, fully adjustable, set it up with a low boost setting (currently 15 psi) and high boost setting (currently 20 psi) and toggle between the settings with a covered switch on the center console. The truck can safely run in the high boost setting with the water/methanol injection system and the tuning from the FAST engine management system on 92 octane.
ATR in tank tandem fuel pumps (340-ltter per hour each) at 10 LBS of boost the 2nd pump kicks in monitored through an adjustable Hobbs switch.
75lbs injectors
Terry Houston 3-inch down pipe (with a manual dump)
3 in. custom throughout (removable high flow catalytic converter)
Custom test pipe (replaces the high flow catalytic converter)
