Glad you mentioned the TQ. I caught a lot of **** from a few people for getting the Tri y headers. I remember them saying " They would be awesome on a truck " but I went with them anyway. I saw Dr Whigham put them on his C5 and it made awesome numbers with just a tune. Made more TQ than HP I think. So I figured the ported fast 102 might be down on TQ so going with the Tri y would complement it. Hope I'm making sense lol.

Hey scotty, I been tossing this around. See what you think.
You trapped 119 on your old tune and made 380-ish HP on that oldvtune. That about right? And nobody really has an issue with that. Now, whatever mods you had, you had a TON of KR, which now I'm thinking must have been fueling related. I suspect the WB on your previous dyno tune might have been off on calibration.
Anyway, there isn't much you need to prove here. It's just LS1tech. You've made a ton of track runs already, and you'll go back. Even if you "only" trap 123 and ET around 11.5, nobody will be calling BS on your power. They'll be calling BS on your mod list.
I for one am very curious to see how you do with your current list. I'd also be curious to see how you do with higher ratio rockers, lighter springs, and possibly some oxygenated fuel. See how far you can push that stock cam and heads!

No thanks. No need to swang from another dudes sack.
So did you gain all that power from a tune?
If you trapped 119mph, w/ 389rwhp, you should be expecting around a 6mph gain from the power you gained. Get around 125mph next time out.
What is the weight of car?

Uuuhhh no.
It trapped 129.xx in +2k da. Been as high as 131.3
The 1.2 60' was a freak of something.
I can't say i think it's a timing error but that's another story.
Yup

I dyno'd on dr's last time to. So that could also be to his favor. Either way i am implementing similar mods. Just haven't finished them up. His engine is fresher....mine has 90k on it. Many small things like that make me think his #s are spot on. I'm hoping to pick up a few hp's so hopefully I'll get close to his numbers.

You know what Scotty, I could give two ***** about the dyno numbers or even track times They are what they are and will be what they will be. This Z is a major upgrade over what you had, is a badass car, and you should be dann proud of it!

Scotty... do you plan on upgrading to a set of aftermarket heads? If so which ones are you looking at?

He and i make the same tq. The tri y seems to help his carry better up top. But we are comparing this on different dynos although the same brand.
I had my doubts on them. I know they can work if tuned right fir the application. I just wasn't sure if they really did that. Seems like they did!
Not really hard to believe. I'm at 417 and was running through a y pipe then. I have rockers and he doesn't (4hp) but his exhaust, cai set up and balancer are no doubt better. He is also running through a stock 3.42 gear vs my 3.90.
I dyno'd on dr's last time to. So that could also be to his favor. Either way i am implementing similar mods. Just haven't finished them up. His engine is fresher....mine has 90k on it.

as a separate comment the tri y stuff is interesting, might have to do a little searching on that.

A carbon drive shaft is nice but $$$$$ saves some rotating mass but the diameter is so small I'm not convinced it makes a difference
