well you would know if you blew a piston unless your retarded. If your having ring problems you need to do a leakdown test and that will be a def. answer if you are having a problem. If you really want to make power out of a sc car you need to have all the cooling mods you can get your hands on and 2nd raise the compression. Doing that will allow you to run a bigger pulley while still making more power so this way you don't create as much heat to begin with. I really can't wait to get this manifold on my car because I should be looking at IAT2's very close to IAT1's allowing me to run as small as a pulley as I want and still be able to make a good amount of hp.

^^ My car would cruise fine, "idled fine" to the untrainied ear, but one look at the interceptor and the amount of misfire it read clearly told a different story...that and goin WOT and having my dipstick pop out, compression test confirmed she was done. Though like I said she cruised around absolutely "normal."
Lemme know when that goes down, I'd say I need to do that myself...
What kinda IAT2s you guys seeing on 3rd gear pulls? Mine shoot up to about 170ish, then shoot down instantly...cruising, my IAT2s are always lower than my IAT, unless you sit a light for a sec, then they creep up for a sec.
When I ran Tim, we did back to back 40 rolls...car seemed like it ran a little better the second time around, I consider my cooling mods "minimal." I need a 2.8 or something, cant imagine what'd they be like.
ran ish again and kevin with the fast 4door si... me vs kevin on a dig i won by 1 car. me vs. ish on a dig i won by 1 car. on a roll... Ish is basically being heat-soaked like a mother phucker so i wouldnt even call it a race. even though im running cool as anything. i think me and ish should do the stu mod def

damn, thats crazy...these damn things are just gonna go somehow eventually...
See heres my thing though on IATs. We're are always worried about IATs...If your car is heat soaking really bad, and actually killing you run after run, I definitely see why you wanna battle IATs but shouldnt the actual head, block be ok? ie. Aluminum has a melting point of what? 600* so, technically the HEAT wont "hurt" your motor(I say that loosely)? What the heat is hurting is your performance right? See where Im gettin at w/this?
Seems like common sense but my little theory is probably skewed...Im saying heat is ONLY killing performance, you cant run as much timing, you cant run as lean. Okay, If I make 300+whp on a 2.5 w/high IATs. Thats all it is, 300whp on high ass IATs, right? Wrong?
As "uneffecient" as it sounds, if it can get the job done......just been thinkin bout that lately

Ok first of all if I think I have a blown motor I'm not sticking my ear by my tailpipe and listening for a sound change to know something is wrong with my engine. Like I said doing a leakdown test is the correct way to do it.
dom heat will hurt your motor. that hot of air inside your cylinders can cause hot spots on the cylinders walls or more commonly on parts of the combustion chamber or head. when that happens you risk the chance of pre-ignition or worse detonation. you will not hit 300 hp with high iat's. cold air is more dense than hot air their for more air inside each cylinder. That is why i said before you see people making 250 hp with a 2.5 although they do make a lot more torque for the reason torque is down low before the supercharger is really spinning and creating heat. You have to keep your intake charge cool to make the most power. the hotter the air the farther the molecules spread out and vice versa when the air is cold.

I definitely feel you on heat hurting the engine and parts so to speak, my old cams were shot w/heat spots and I had to replace all the sleeves in the block due to the stock pistons do a number on the walls, which Im sure was because of heat. Cooler is better, no doubt about it, I was just thinking "practical" on aluminum's heat properties combined w/what our IATs are etc. Either way, Im almost sure this s/c is coming off for a turbo in the near future, this heaton is a killer.

why are people afriad of raising their compression ratio but have no problem running 2.5 pulleys. what is the difference if I run a higher compression and a 2.8 pulley or bigger. The only diff. is now I'm making more power and the supercharger is now in its efficiency range.

tuning isn't a bitch. Either learn how an engine works and wants and figure out how to use hptuners or pay somebody who does.
yeah I saw jimmy at the shadybrook farm meet last night and he gave me the bad news. that f**ing sucks man I wish that upon nobody.

Funny you mention that when a page or 2 back you said you aren't tuning cars anymore cause of the liability. I also doubt that YOU have the capabilities to tune correctly for higher compression.
Exactly I'm not a shop nor do I try and make money for anything that I do with hptuners. If someone needs a case relearn or something I have no problem helping people out especially since its free. What stops somebody if they really wanted to to sue me if they blow their engine up. Also I never said that I had the capabilities of tuning a higher compression engine, atleast here I didn't. Please do not put words in my mouth. You can ask probably anybody in this thread that I really don't post all that much and I keep to myself. I do however interject occasionally and try to help or teach some of the information that I have gained. I do not know everything nor do I act like I do. I simply through some facts or info about a couple of things here or there and all of a sudden you get defensive and call me out. You are like just about 90% of the population on this website. They all know everything and have to hate on everybody. You sir are a tool and I will ignore every post with your name attached to it.
