I know. It seemed like a couple years ago the highest cam only numbers were around the 430whp range. Lately there have been a few at 450whp posted and now 460+. Wait a couple more years and everyone will expect 500whp with a cam swap.
My C5Z put down 462/400 with just cam only stock Intake manifold and stock 243 heads (untouched). The printer at Quality Motorsports had a mind of its own that day and on the highest run it did not print the TQ just the HP. But out of 5 pulls the car was a solid 453-462hp and 395-400tq.
I think the dyno had a mind of its own!!!!!!!
Time for it to be recalibrated

[QUOTE=ctusser;1576882786]I have the Trex cam by Thunder racing. I am going to be having it dynoed again so I will have a update with the new numbers and this will be a on a totally different dyno.

I have been seeing 418-425 rwhp roughly on the forum here with lt headers, cai, cam, and tune. klr z you are saying you have a cam only correct and i assume a tune, stock manifolds got to kill a cam it needs to breath, i would think 405-410rwhp tops without. JMO
What cam you running

I worked a corvette (C5/C6) specific performance shop for a few years and in that time I can only remember one person getting heads and headers done without a cam in a C5Z, I dont remember the exact results but if it was something even somewhat impressive I would have. I could see maybe 410-415. Better flowing heads, intake etc is only going to do so much when the cam doesnt need that much air. I like the out of the box thinking and hope it works for you. There was one 03 C5Z that with just a CAI (I think Vararam) and a catback (maybe bullets?) and a tune put down 382rwhp, I thought that was pretty impressive.

As a long time engine builder, fabricator, etc. I've built many platforms over the years. As I move and learn more about these LSx engines, I have tried to establish what's been done and what's yet to be done.
Like many other genres I have experience with, the Corvette crowd has a pretty typical upgrade path that 95% follow to get to "x" hp and what not. What I haven't seen much of are those who try to break the path.
One would be, who's explored the limits of the car while maintaining stock heads/cam. Combinations with headwork, intake mani work, etc. C6Z whp with a C5Z combination that is mildly mannered is the ticket IMO. Has anyone pumped up the c/r a tad, worked the heads/intake and kept the stock cam to see how much power can be made while being able to lug 6th gear at 40mph like a stock cam car will?
This feels to me to be the path I'd like to go with this car. I'm just wondering if there are any others out there. Any aftermarket companies on here ever really explore what you can do on a stock grind?

Calling me a "douche", yet not even spelling it right is laughable. Saying "hey look at me, I build race engines"....well, I mean, I do run a company that builds racecars, forced induction components, GTM's, SLC's and tunes EMS's...I must know something to be here. I've built more engines than I recall so...I have SOME experience I think. The guy who called me a douche....what do you do for a living? You've done a few bolt on mods and troll a forum puking up info you've read?
As with most things, I'll do it and share with those who value the information. On engine building forums, things like this spark discussion on how to make such a thing possible, on enthusiast forums it sparks trolls.
Cams dictate an engines ability to breath yes, but saying YOU CAN'T MAKE POWER without an upgraded cam is ridiculous. Has anyone ever taken note of the power cup cars make, or ALMS cars with ridiculously small inlet restrictors in place? It CAN be done, but is the effort worth it is the question. Is the investment worth it? Will I do it to see....mostlikely yes...
I have a full shop, countless LSx motors here, a dyno, three GTM chassis, two Corvettes and time. Doing something like this benefits the members and enthusiasts, as well as our business. If I thought so narrow minded about how engines make power, then I'd have never gotten into building cars. That's like saying 800hp isn't possible unless you have 8 cylinders. Words spoken by those who think they know way more than they do.
We all have a lot to learn...some continue to learn, some figure they got it all covered. Doing what I do got me where I am today so....troll all you want there Zeevette...maybe I'll see you at SEMA or PRI....ehhh...doubtful right....yeah I thought so.

Theres no way thats accurate with just those mods.

I really would like to meet you at SEMA. I think it could be very educational. You can explain your magic ability to extract unrealistic amounts of HP (what about TQ?) with rather severe restrictions, and I can respond to your name calling. I have gone, but it's more for entertainment, and seeing what's new, than making business contacts. Cars are a hobby for me, not a means of making a living. Be that as it may, I stand by my opinion, of it being impractical, improbable, and certainly not cost effective to do as you claim. I believe you are wrong, and I can spell douche.

You could conceivably hit 450whp on a Dynojet with 13.5:1 compression with stock cam, full bolt ons, some head & Intake mani porting, EWP, UD pulley, Lightweight flywheel if you do run race gas. But to get it might require dome pistons which would eliminate the stock bottom end premise.

When I had my ls6 cam only (with supporting bolt-ons) I was at 430/383. But this was appeox 4 yrs ago. Those numbers are passed daily with the newer cams.

You can't answer a straight question, because you have no answers. For such a smug, self-satisfied know-it-all, you contribute nothing. What's impractical? Your stupid idea of bettering a LS7 without changing stock heads and cam.
