Also Im going to contact Patriot Performance and see if they would be interested in testing thier LS6 Stage 3 head as well on this test, along with any other head producers that would be interested.
Im going to do this with a ls6 intake on both setups with a ported throttle body. And i am going to try and do it with a 90mm FAST LSX intake (i have some 78mm lsx's here) and a 90MM FAST Throttle body as well on the dyno testing. This is all being done on a 11.5:1 91 octane, ls1edit tuned, large cammed, 408 stroker on my dynojet. Im not a producer of any parts, only a retailer so i have no biasedness in anyway...im interested in solid results.
Im going to come back and give full HP/TQ and airfuel/tuning graphs results independantly and unbiased, as im going to stay with and purchase the better head and return the other.
This was brians idea, but im not sure if Jay @ Absolute is willing to send me the best he has. As i plan on purchasing the better of the two and give some good ls1tech results.
Jay @ Absolute : Would you be interested in sending a set of heads for this back to back dyno test ??? I have alot of faith in your heads being a solid contender. And i think a ton of customers would be really interested in seeing the results. Like TEA is interested in testing as well. Please respond with your thoughts.

What makes you so special that they should send you their heads for free? Trust me when I say that you aren't breaking any new ground in the LS1 world, plenty of people have run fast with nitrous. ARE's 422 ran 8's on n20 but that was with C5r heads, a custom intake, and a big solid roller; and to top it off they have good tracks to their advantage, I can say the only place you'd have a prayer of running well in CA is Sacramento or Pomona. Also you say you have a raceweight 2900 lbs (that means with you in it) yet you say it's full interior, C4's weigh around 3300 lbs without driver, that's means you've removed 400-500 lbs from your car, I don't really see who you could do that with a full interior.

Yea..I know the patriots arent really up to that level, but so many people are bent on the "stage 3 ls6 head" they have that maybe they will learn something from it.
I just have to wait for jays reply, because i cannot afford to purchase both sets of heads to do this...I can cover one, but not the cost of both.
TSSovr4U: I went 10.5 on the old 450 rwhp setup....with the nitrous bottle out and 1/4 tank of gas my race weight is 2900 lbs with me in it. If this setup does 490-500 rwhp, i think i will push it near the 9.9's on the transbrake....
Kinda curious have any hydralic cammed n/a cars went 9's on motor yet?

Linear, he stated he would purchase the best set of heads and will be sending the other sets back. He's not just getting 3 free sets of heads, rather he will be getting a try before you buy advantage which will also help other big cube engined folks out there.

The cam really didn't make much diff as the Vette ran 154mph with a 242 hyd.as well. With 300 lbs lighter and seems like the car works great
mid 8's may even be there.Just a question, wasnt the post asking to find what the best N20 heads were? You are now doing a back to back(great test by the way) in NA form. How about if the best NA heads perform not as good as the others? I guess we will never know that
Just an observation not anything meant by it. Last edited by Nick Agostino; 02-10-2004 at 06:55 PM.

dont think you're gonna hit it w/o some c5r heads. realisticly, are's motor took a 400 shot to get to the 8's and only weighed a tad more. everyone knows that once ya hit 9's on these motors the heads are pretty well maxed out. best of luck, and i hope that ya do, but the power just isint gonna be there imo.
aside from that, sponsors, send me some stage 3xx heads, and i'll go for 7's

I think the head testing would be great! I would be willing to send one of our heads to a shop (independent) for testing. To see which heads are the best in a given stage. We really need to find a shop that has nothing to do with LS1's to do this at. This way they would be unbasis. We should start another post though for it, if there is interest.
By the way, I would say that both Jay's and TEA's heads are good and both could do the job. But I would have to go with Jay's heads if I wasn't running my own. More and more of my customers are running Jays heads. There's got to be something good with them!

I could take the car down to 2500-2600 lbs without me if i really wanted to pull weight out of it..but i like keeping the car full interior/nothing stripped etc...
