Which option is best....??? OK, I'm gonna put my car back together like it was, and I want to fix it so it has a lower probability of breaking again. I've got LS1Edit on the way so I can control timing, so that's an option...
I have to decide whether to just throw a stock head gasket back on or go Cometic, and then if I should go thicker for less compression.
Or should I put the bigger pulley back on and settle for less boost
Or should I try to fab up a small intercooler to bring my IATs down a bit, even 50-100 degrees would help.
so here's the question of the day for me, if I were able to fab up an intercooler and get my IATs down, should the stock head gaskets be OK or should I still look to lower compression???

Re: Which option is best....??? I've gotten word that the Cometic gaskets do a much better job than the stock gaskets. Whether you need to lower compression probably depends on how much boost you anticipate running...

Re: Which option is best....??? powerdyne 6# kit right?
shouldn't have to do anything special except tune it. what's your list of current mods?
I can send you a couple of different edit files to give you a baseline of where to start.
I am going to do water/alky injection to combat the IAT's so I can crank up timing but even without it the car is running well. I dyno tommorrow and I will let you know how it does.
My current setup is 6# pulley, 36# injectors, mac's with cats, supertrapps in place of stock muffler. Computer tuned by me with ls1-edit. I will then bring the water/alky on line, then comes heads/cam/ls6 intake <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" />
I'll let you know how it does tommorrow.
Also I did another powerdyne car, he does not have headers just the blower, 36# injectors and a borla, and on 91 octane, 401/406 and he beats it daily. no issues. It's all in the tune. He sees 7psi at 6200 btw.
Our powerdynes don't push enough air to stress over compression IMO. Especially if you have headers,cam,heads, etc... Just adding the MACS lowered my boost 1.5#'s I have to wind the shi@ out of it to see 5.

Re: Which option is best....??? I'm going to put a stock head gasket on the car and put it back together as-is. I'll be getting LS1Edit soon, so I'll just baby the car till then. I'lve pulled out the HPP3 programming (sold the HPP3) so my stock rev limit should keep me out of trouble till I get LS1Edit, then I'll play around with possibly intercooling to get my IATs down. I'm not re-installing my AC condensor, since I may have to pull that crap out again soon it I do the intercooler.
I *may* also install the bigger pulley back in the SC, or maybe run the stock intake (not through the fenderwall) and see where I end up boost-wise.
hopefully the car will be running by Sunday, so we'll see...
