Start by going back and quoting where I said you were wrong.
Next, the LSJ head can't touch the K20 head. Its basically done at .400" lift flowing just under 200 cfm and 208 cfm at .500". Same on the exhaust. Its done at .400" flowing 147 cfm on the exhaust side and 149 cfm at .500. The K Series head blows it away. I hear it flows close to 300 cfm on the intake at 500''.
Thats why when I heard the numbers you put down. I knew it wasn't done on a unported head as you you leaf most everyone on to believe. I do know a thing or two about cylinder heads and there's no way your making 340's to the tire with that head untouched. Not unless you spray the engine. I certainly don't know the LSJ engine like you do and I don't need to own a Cobalt to know that you can't make that kind of power on those heads unported.
Just as relevant as your question was on asking me about the LSJ and K series head. Why don't you tell me how much the factory small block Chevy camel back heads flowed vs the Vortech head. Which is better? Thats too easy because you can probably look it up on the net. How about you tell me what you know about the early 1960's factory big block Chevy cast iron rectangle port closed chamber heads vs the open chamber oval ports. Which would you use on a NA 468" engine turning 6000 rpm maximum. Or how about Fords GT40 vs. the GT40P. Which is better and why?
As for owning the current highest whp stock motored supercharged lsj. Nope, it probably wont be added to my lifetime list of accomplishments or that I will be remembered by when Im gone. I was however a helicopter mechanic in the Marine Corps for 5 years. I never mention that to anyone because it's not relevant and Im not one to blow my own horn or ride my high horse. Did one tour to Afghan and one to Iraq. But I did turn wrenches on 50 million dollar aircraft, not just cars, in which the lives of not only myself but the crews and pilots depended on.
What do you know about those engines? What do you know about working on them and trouble shooting them when the pilots complain about not having enough power? What do you know about listening to the pilots comments on flight controls and trouble shooting them to correct the problem. What do you know about working on 3000-4000 psi hydraulic systems which drive the flight controls. My squadron has a legacy and history that dates back to Vietnam. Why dont you search the internet and find out why HMH 462 is called the screw crew
I served my country and gave the ultimate sacrifice. Did you? Im not looking for thanks. The Marine Corps thanked me twice a month while I was in. Im just pointing out that its guys like me that served our country, so guys like you can have the luxury of calling guys like me ignorant.
Happy New Years,
Rodney
PS. As for as your down pipe. I can make that and weld it myself for under $100 I bet. You got ripped off if you spent $500.00

Thank you for your service to our country. however 340whp on a stock head is NOT as impossible as we all think. I have been flirting with that number for a while on a couple stock head, TVS, methanol injected, cars and I am by no means as skilled of a tuner as Bryan. oth cars that are approaching the mid 300whp mark are running 2.8 and 2.9 pulleys with 7gph nozzles using a mix of roughly 80/20 meth.
Steven,
What does a screen shot of your HPL file prove? You have an iat2 of 115 after a 3rd gear pull. Thats all. It doesnt prove that your method is better or produces more power.
I love you all.

i'm the one who tuned/tunes his car. it's peachy for summer fun.
and rodney, your ignorance on the winter tune thing is a shame. it's simple. massive air temp changes and the lsj ecm do not get along. if the ambient temp is 50 degree's during the day and you're running 12.0 afr everything is fine. temp drops to 21 degree's later that night, or the week. your afr is NOT 12.0 you're well into the 13's on afr. ecm lack basic compensation for temp changes.

Anyway, Like shaun said, we've discussed it quite a bit a while back, and i think we just agreed to disagree, but im on the side of going large on nozzles. I would go as large as you can before bogging/flooding and enjoy (or ideally just switch to E85...but alas, no E85 near me). I like pushing it to the limits...and god save me if i ever have a meth pump failure (excuse to upgrade!)

how many ******* times do i have to say this before you people stop putting words in my mouth. I HAVE A STOCK HEAD ON MY CAR ASIDE FROM VALVE SPRINGS. it has been this way since 35k miles. that was almost 60k miles ago.
got it?
steven. i am not impressed by your iat's. mine runs cooler without meth.

last time i was on the rollers, it was 62 degree's in the shop. started at 110 degree's iat2, ended at 125 degree's. 2.6 pulley on a tvs. no meth. only a fmhe for "added" cooling.
from 2k to 8k rpms.
we can keep playing this game if you really want.

im assuming the ported head you referred to in my quoted post is not installed then? if so, thats all i was looking for in an answer.

i didnt put words in your mouth, i quoted you directly. They are your exact words, and there was no hostility on my end. chill the **** out...

Im well aware of what it says...not sure why you're telling me. In the thread, he made some good power numbers, i said he needs to port his head and see what it can really do, then he said he already had a ported head...it made it sound like it was installed. He also then clarified that it was a hand port job, and i figured it might be a mild port job. Again, im not sure what you're defending or arguing, because regardless, his response was way out of line. I was asking a simple question

i'm defending or argueing because he alsp happens to be my friend outside of .net and i'm starting to get fed up with the same stuff he is.
i've seen his car in person. i've seen his engine bay in person. hell ive ridin in his car. i've seen the pile of parts that aren't on his car. i don't know where he got the reputation of being shady and not sharing stuff he does with his car. i'm gonna guess that it carried over from not sharing things about his tunes and how he does it. which i don't blame him. if you made money doing something, learned and taught yourself how to do the trade, and are very successful at it?? why the hell would you tell people how youre doing it? but him being shady about whats on his car and whats not. is false. his motor is 100% stock save for valvesprings, which anyone could have guessed that with his 8k rpm redline.

so after sifting through all the crap, i think i got out of this thread i should run an m5 at the largest for my current setup...at what mix% though? 50/50, 75/25? 100? id like to have at least 75/25 so im not going through the meth too quick haha
