383 LT4 Hits the dyno Wednesday!

Just wanted to say Thats really Healthy and with no overlap ur right Its right where it should be. Thanx's for telling me the details of the build. Its just natural for me to always pry. Can u tell why u didn't get into the high/mid 11's on the A/F? it seemed like it liked it getting closer to it and kept making more?
Also I bet ch ya with a cranking compression cam dial in you'd get over 400rwh and a 11.5 or so A/F

I also want to stress that it would have made more power if I would have ran it to 6500 or so rpms. I have a rock solid valve terrain and I use to spin the last build to 7200. I just want to make this engine last so my rev limiter is set at 6300.

Every once in a while, I find a pretty big gain when I advance the cam way more than normal/ I have seen up to 20 HP when I went 4 or 5 degrees more than normal. You just have to try it on your combination. I think in general, lower compression engines will respond more to this idea.

This is all relative. The engine I was referring to was a 347 Ford. It had 10.5 to one, but a fairly long cam(248-258 on 108) when I advanced it to 8 degrees total, It picked up power everywhere from 4000 to 7200. It was cranking 185 before, and it when up to 197-198 with four degrees more. It seems the 10-11 to one engines might be the ones that like the extra cam advance.

One of Smokey Yunick's recommended ways of finding the "sweet spot" in a cam was to advance and/or retard the cam until you got the highest cylinder compression reading while cranking the engine with a fully charged battery.[/quote]

I wish I was as competent at building engines as alot of guys lol. Its a whole lot of work to tear back into this thing to degree it in and check for max compression! It going to stay like this until she blows or I sell the car! lol
#64
actually 10.1:1 compression is not really low for forced induction application with that kind of boost......that thing is going to make a GREAT amount of power......just keep it from detonating.....that will be your enemy and issue.....hopefully the tune you get will allow premium pump gas......
Jesus, I was happy with my 350rwhp car; seems like nothing these days......times have changed since I did my build..........

Thanks! Im headed to pick up the procharger from the fedex store now! I hope to have it on the car tonight! The tune will be a sinch because I will be running the previous tune I had with the old blower, but I will do a little wot enrichment! well maybe alot! lol
#67
I spent 6 hours out in the shop tonight and got the blower completely installed and fired her up for the first time with the D1SC! She sounds amazing! Now its time to see what kind of power she puts down! Here is a video!

That's why he has 2 Corvettes! JK JK.
Seriously though, very nice! I wish I had the funds freed up to spend the cash on boost for mine right now. Damn student loans and retirement plans/investments are taking up too much of my income. Cant wait for road america next summer. We should get to planning it before next spring so people (like myself) can get the time off.

Yo Smooth We need to see a Test Beat with someone taking video in the passenger side with a through the windshield view or mount it somewhere good. Thats one of our Perks for hanging on in ur thread. We r all Speed Nuts and wish we all had some boost so we can at least sit here at our computers and drool while u go on a blast
Something like these 120mph blasts

Ye-ha Dam those pull hard and wind up quick and I love the oil pressure on those. No thats not mine in the Video.
Why do u think the C6-Z06 1/4 mile times r so close to C5-Z06 times? They got twice the motor and more rubber?

Actually the C6 Z06 is quite a bit faster than the C5Z. I have saw them (c6Z) run 10.80s on radials and bone stock everything else. A c5Z stock will run high 11s on radials.

Nice Video by the way and yea they are almost a good 1/2 sec Quicker just play-in, and pulling over a g in corners and that dry sump is sweet and needed earlier models were sucking air in the corners instead of oil because of the good cornering I love those 6's
