Chris you had AFR 205's before correct? Those are a 66cc chamber. If you were at 11.0:1 with a 66cc chamber and you now have a 72cc chamber you are at about 10.2:1. 6cc's is usually worth about 8/10ths of a point of CR.

Correct, I had AFR 205's that were milled to 59cc and Cometic .040 gaskets

Now its the 317's and GM MLS gaskets

Very nice numbers man. Good job Taylor.

Makes sense, not sure about your cam but as far as setups I am using -2cc flat top Diamonds now for the past 6 years. My LS6 heads were CNC and hand ported to 77cc's. I used a cometic gasket (.060") only because with my heads and block decked (clean ups during rebuilds) and the 6.125" rods I used...my pistons come out of the hole .014"...about double what the stock pistons do....otherwise I would have used the stock GM MLS head gaskets. Cometics MLS gaskets have been really good to me.



I actually think that the APS and ATI's revised twin ICs could be a better option for Roadcourse setups (like LPE engineered) because they are efficient enough liimit pressure drop and will flow enough CFM to support big time hp. Back when we were all going to single FMIC...the twin IC options were pretty small and really only aimed at around the 600-700rwhp mark.

I think the new twin ICs would be helpful for sustained HPDE as the area immediately in front of the Rad is open using the Twin ICs vs. a FMIC.

Of course AVB tracked the hell (HPDE) out his car and in hot weather 100* temps. From what I could see from his data logging is that his coolant and oil temps were really even with an FMIC..but he had a Tigershark front end as well.

It would be nice to see how much difference (I have to imagine a little) the coolant temps would be with Twin ICs..although it might actually make a bigger difference in stop and go traffic.

I haven't had any issues in Stop and Go traffic..but I could easily switch out my FMIC for Twins if I wanted to try it as my Turbos could route the charge plumbing to Twin ICs pretty easily.

^ I kind of like the idea of the twin IC's also so my radiator doesnt get restricted in anyway whatsoever, esp since I drive the car ALL the time in this HOOOTTTT Louisiana weather!

I also run the Tigershark front fascia so that helps airflow even more

How many Lbs of boost? WHat type of fuel? Thanks

Corvette-Chris

13.8 psi and pump gas + meth

FactoryRaceCar

Congrats Chris! Well deserved

383c5

What is max boost you can run with your setup?

Corvette-Chris

Thanks Nouman....Its been a long time coming

Not sure to be honest with you...I really dont see myself turning it up past what its on. Ive seen other forged 347 cid motors handle 18 psi so I think my motor would be ok. The transmission and turbos probably wouldnt like it for long periods of time

Congrats Chris!! Have you gotten to drive her yet? I'm sure you have a list of local victims lined up.

Corvette-Chris

Hopefully him and Jason will get you sorted out VERY soon

Corvette-Chris

Thanks Bret. No I havent driven it yet. Im actually coming with a trailer tomorrow morning to pick it up from DP. It still doesnt have a bumper on it so I dont want to drive it home and possibly damage the IC's or Radiator.

Im sure me and some local guys will get into something LOL
