This thread is for all you SmokinVettes out there that have questioned or pondered the thought of a Naturally Aspirated engine. The supercharger and twin turbo companies have done an excellent job of marketing and engineering of some incredible components. We have taken delivery and installed one of the most reliable superchargers on the market - Magnuson - thanks to the folks at Callaway!

Our other 2005 C6 (black) project Vette is getting a whole different engine set up. Thanks to Tony at Air Flow Research and Mike with Haddad Motorsports, this Vette will potentially push more power than our blown engine?!

Need to be motivated? Here is a recent video of Tony's naturally aspirated C5 beast! The video starts off slow as we traffic clears, then speeds up a bit at the end! http://www.youtube.com/watch?v=bcqJW82Q1Q0

With all this said, if you have any questions that you have regarding Naturally Aspirated engines ONLY post them here. Blown motor questions we be addressed in other threads! Thank you.

How much HP is that C5 pushing to the ground??!

Had to watch that video 2x!! Second time turned up sound! LMAO!! That Vette is a monster, would be interested to know the HP/TQ what has been done to it also!

Amazing!!!!

:eek: What do you feed that thing??! I showed a couple people that video and everyone has the same opinion! Just when you think you have a fast car, you see something like this! Love it!

All the previous post clearly show my thoughts as well. Would be interested to learn what you did to the motor?

Guys,

The silver C5 in the video belongs to me and has been the AFR poster child for our LS line of cylinder heads (the car we have been using for most of the Gen III R&D efforts).

It currently has a 383 CID engine with our 225's and a small street friendly solid roller cam. Its a very optimized package that I built personally and is currently generating 535-540 RWHP (610 documented flywheel HP) with close to 500 RWTQ as well (485-490 usually). You could drive this combination every day, yet it still knocks down close to 25 MPG on the freeway and will run high ten's at 129-130 MPH.

Here is a link to a very detailed thread of the engine dyno testing I did over a year ago....

And here is an even better video of the car in action....

Enjoy!

PS....While N/A serious power is much more difficult to produce, the results and looks on peoples faces make it all worthwhile. It just takes time, money, and the right combination with the latter being the most important.

PSS....In the event I roll up on something really serious, I also have a Nitrous Express wet kit which would be useless till at least 3rd gear on anything but a purpose built drag tire (ET Street or straight up slick).

that just shows you never know what is under a hood! What hood do you have on that? Very :cool:

watching these videos gets you thinking of what possiblities there are with these cars. beautiful car!

The possibilities are endless.....half the battle is figuring out what works the best for you.

Punisher....the hood is an RK Sport hood that I really like as well.....now if I can just find enough time to paint it....LOL (Luckily the hood is gray gelcoat and my car is silver so it doesnt look that bad unpainted!).

I need to have Alex or Greg transfer all this dialogue to an actual thread....we have been responding to basically an unrelated sticky. I will give them a call on Monday.

after watching this video I look at my car and :( on a positive note that is inspiration of what can be done :D awsome car!

WOW! i just bought first vette last week, i like the sound of that vette, it sounds like a race car.

so cool... i'm at a lost of words:cool:

For those where money is no object, like the Corvette Racing Team (aka Ron Fellows and crew), Katech builds some tremendous NA engines. Katech will do engine upgrades as well as build new crate engine applications.

Media does point heavily to TT's and Supercharged engines and your forget the "roots" of old school muscle. NA! Great vids, that C5 sounded great, what exhaust is being run on that car? It may have been posted and I over looked. Sounds great either way.

I thought this was a neighbors car! I can clearly see this one has more power. I'm new here and will need to get my neighbor on this site for him to post his 2002(think its a 2002??).

What cam is in this vette in the video?

Guys...

That is my personal car and the one AFR has featured most of it's R&D on concerning the AFR Gen III cylinder heads and related packages. I head up that department at the company.

The exhaust is something custom I fabricated utilizing C5Z06 titanium mufflers with a pair of rear cut-outs that allow the exhaust gas to bypass the mufflers and the restriction they represent. Note that the exhaust still travels the entire length of the system (thru cats) and still exits directly out the tips....its simply able to bypass the mufflers with the cutouts open via a remote switch I located on the frame of the driver's seat. In the video the cut-outs are open as you can tell by the more in your face "pop" emitting from the exhaust. Sounds wicked at WOT....the video doesnt do it justice. When I close the cut-outs it still sounds good but far more muted and the WOT blasts are much more stealthy (as is the idle and cruising around). Its my own personal version of having your cake and eating it to because you always grow tired of too loud an exhaust and always want more from too quiet an exhaust.

Regarding the cam its a small street friendly solid roller in the low 240's at .050 duration but on a wide LSA to keep it reasonably tame and help the high RPM charge. Drives down the road perfectly and I can lug it as low as 1100 RPM's without protest. The idle is about 925 RPM btw....

Have a good weekend!

Tony

Tony thanks for the post great seeing again this weekend.

Tony we just received the AFR heads in yesterday... VERY impressive!!!

Are there any photos available under the hood stuff on this car? Impressive video would like to see those photos if available.

thanks - Jim

Jim...

I could snap a few by the weekend and probably attach them to another post. It looks very stealthy IMO....the only real give away anything is going on is the larger tube headers (1.875) and the gray FAST intake which one day I will paint black just to fly by under the radar even more.

Give me a few days and I will put something together....

Cheers,
Tony

Very cool, I have had my vette for 6 months or so and now it seems that I notice more of them on the road. Never have I seen one built up like the one you have! That was awsome! Watching the videos gives me something to think about. Was thinking about a TT, now theres more on the table.
