S/C Install finally FINISHED Hi Bought a Vortech SQ about a month ago http://forums.stangnet.com/showthread.php?t=594221 Finally started the install this week. Jay and Tom did most of the work Wednesday. (my sons) Wednesday night pulled everything down to and including the heads. Why the Heads?? Putting Cosmetic gaskets on to lower the compression using .71 custom gaskets to lower from 10.1 to about 9.6. Waited on the head gaskets til tonight. Then reinstall and torque the heads.. Jay and I ..Done Tomorrow hope to adjust valves, install lower intake, headers, 42# injectors then the fun start the S/C install. Steve
Wow, thats a very thick gasket!! Be very careful on your tune, that thick gasket is gonna kill your quench and make you more prone to detonation, something you don't want with a blower. Pull out extra timing to be safe! You could have just had the chambers opened up a little to lower the compression w/o hurting your quench and use a .039 ish gasket.
DO NOT, I repeat DO NOT think about romping on the throttle after its installed. I blew my heads off the block just a few days after the blower was installed. Get it on a dyno first. Get it tuned then let it rip. It probably won't run if your using 42# injectors on the stock computer anyway.
you did the right thing by lowering the comp some . keep us updated on the progress if you run in to trouble just ask
I am pulling the chip and taking it to the tuner before I start the car and he will put a tune for the supercharger and injector's on it... Then First trip is to http://www.paulsautomotiveengineering.com/ to see Mike for it's tune. I know it will be tempting maybe I'll let my son drive it over there. Steve
Quench is the distance from the top of the pistons to the bottom of the head deck. The further you make them apart, the less efficient your combustion is and you'll be more prone to detonation. As you know, detonation isn't something you wanna risk on a blower or any power adder. If you wanted to lower the compression, your best bet would have been to open the chambers and run a .039" ish gasket. My quench is .039". My block is zero deck meaning my piston comes level to the block deck. So the only distance seperating them is the .039" gasket. I believe optimal quench is .035"-.045" range. You'll probably be fine but its not the ideal way to do it. Personally, 10:1 is fine with a blower IMO with a good tune.
Hi Saturday evening Jay and I worked til 5pm. This is what it looked like when we started Saturday around 10am.
The 42lb injectors from Ford are Lime Green Top. Some companies that make injectors use same color for their injectors. The ones in pic look like they might be Bosch injectors.
Supposed be 42#'s out of my sons car he went to 60's. I've decided Vortech's instructions suck!! These are much better.. IMHO http://neptune.spacebears.com/cars/stories/scprep.html Steve
