2003 C5 Z06 Partial build/Low numbers? 2003 C5 Z06 (M6)of course
TSP camshaft, don't have the specs here/ said comprable w/MS3
Patriot heads 2.02 intake/ I forgot the exhaust
OBX stainless headers, hi-flow cats & crossover
Borla SP2 exhaust
Fast LSXR 102mm intake
Stock 05-08 LS 90mm electronic throttle body
Deatshwerks 36lb/hr injectors
BBK CAI
Dyno Tuned
I'll try to get the dyno sheet posted sometime
Made 504.xx rwhp & 487rwtq.
Read so many stories in GM high tech of FAST intake + large cam + heads making way more power than this.
Car had a few issues and is going to get a final tune as soon as we get the oxygen sensor extensions and fix a few exhaust leaks where the crossover pipe connects in.
Is there any tips or tricks of the trade of gaining a few extra ponies?
Do you guys think these dyno numbers are accurate?
Also I think it was a mustang dyno but I am not sure.

If thats a stock CI motor and a mustand dyno than your numbers are some of the highest I have ever seen. I'd love to see the graph on this one.

It is stock CI, and we didn't have the pistons fly cut because TSP said we were good with the cam and stuff they fixed us up with. I beleive it was a custom grind cam from them, I wasn't really in with that part of it.
We started out not going with the FAST intake and had a prof products. Ended up having fitment issues with the firewall and so we pulled it off and sold it because we didn't wanna cut on a 50th anniversary 8k original mile Z06 lol. That is the same reason we didn't use a FAST throttle body is because if we had did the cable drive conversion we would've had to drill some holes. Too bad FAST didn't make an electronic.
I was pretty happy with the build and thought the numbers looked good. We started saying if we could get 500rwhp we'd be happy. After him talking with the guy who tuned it he had his hopes on 540~ish rwhp and it just didn't happen.
Should have final dyno sometime next month and I'll be sure to post for you guys. We are expecting a slight more gain as the front O'2 sensors weren't hooked up and because of some issues we had with the throttle body at the time it was tuned on speed density w/o the maf getting used. Supposedly* expecting to get up around 515rwhp on the final tune but I guess we shall see.
As far as the dyno, a friend of ours had an 05 GTO w/6.2L GT-1 cam, exhaust,cai,tunec M6, monster clutch- layed down like 430rwhp at Karma performance in Nashville. He came down on this dyno to see the diff and it put down like 427rwhp. An 05 with the stock 6.0L and a few bolt ons/cam did like 410rwhp. Another friend has a new camaro w/headers,exhaust & cai put down 372rwhp on saturday.

I've got a 90/90 on my 02 and it fits ok, is the 102 taller? I drilled 2-1/8" holes in the deck to get a long allen wrench through to tighten the blasted intake down, not much butchering. I'm usually take mine on/off w/3/8" b&d drill.
Also, if your combo really put down 500+ w/that setup, then "that" is the combo to use on those cars!!
Yea i think this is a bit off too. I have never seen any stock cube motor go 500 with patriots. Also torque is most like about 50-60 to high. the only 500whp builds i have seen are parts that are matched together to make a perfect combo. All have worked AFR, or TFS heads. I bet you are making some good power tough. I have seen combo's like yours go 470/420 which is pretty damn stout! maybe a little more with the fast 102.
Haven't I met you? Manager at the O'reily's in Dickson, right? I am The guy you met with the black hardtop Z28 that night. I think you are talking about blue with the Ls3 in his black Goat too and Dank in his silver GTO?
If so, damn good #'s out of your Z06! I didnt know you were that serious about power! You need to get your Revenge on Blue now!!!

Haha, yeah I'm the assistant ~ Trent. I've got the silver goat that I'm doing a few things to. Trying to get ready for the huge rod run up in pigeon forge in april.
Boyd is the one that laid down the numbers in his black Z06. Thing is sick.
Yes and on that same dyno that Blue put down a few less ponies than he did up in nashville.
On the FAST 102mm it fits perfect. Bolts up with no clearance issues just like FAST claims. Car WAS dyno'd with the FAST 102.
Idk we will find out the true numbers with it and I WILL GET A GRAPH when we do the final dyno. Either their dyno is off or we got lucky with a really good build on this.

Yeah Scott tuned it. The only other thing we are actually worried about is because of a TPS sensor issue we had on the old throttle body is that its on speed density and its going to have to go back to MAF. We do not know if this is going to help us or hurt us.
Problems on original dyno tune -
Was about 40-45 degrees outside and a little humid.
Had late 08-10 90mm electronic TB that did not interface correctly with the computer so he had to "bypass" the throttle controls.
No front 02 sensors were even hooked up because we did not have the extensions. He said he ran them as "optimal".
Have a few exhaust leaks under the car where crossover pipe bolts in.
Was tuned on speed density being as with the TB issue he couldn't use the MAF.
I know Scott knows what he's doing hell he took a stock T/A that only put like 252rwhp down on this dyno up to like 340rwhp just with a tune lol.

That's not a realistic improvement. That was more of problems in the tune from the beginning handicapping the car. Scotty is a damn good tuner and we're lucky to have him based out of Nashville.

Its a stock 8k mile bottom end LS6. I'm not making it up, those are the numbers we were told from the guy that tuned it. I don't have a graph, as I said we had problems and knew we were gonna have to go back. The dyno shouldn't be off, as stated and another guy in here that knows me can confirm it dyno'd a gto that put 432rwhp down on a diff dyno and on the dyno we used it put down 427rwhp.
The only thing I can possibly figure is that Scott (the tuner) may have told us wrong. I doubt he would straight up lie to us. I really wanna know myself and I can't wait to see the graph either. I am going to be dissapointed if we didn't hit 470rwhp/450rwtq numbers or so.

I'm not saying the dyno didn't spit out those #'s. I would think it had major spikes in the graph to do it.
IF the torque is that high it will be the highest torque a 346ci , I have ever seen in 10 years. Add that to Patriot heads.
With a setup like yours I would expect 440hp/420tq.

He means crank horsepower
With 12:1 compression A whole lot of port work,Solid roller cam, & lifters. ti valves, Fast ported 102 combo
Maybe that at the wheels

Never really trusted the tq #'s on that dyno, they've always been high. The hp #'s from the dyno are usually pretty accurate from the 20 or so Ls car's i've seen on there. For whatever reason, the tq was always off though. They said they had corrected it though?
