wanting to push the limits of a 408
hey everyone, im building a fully forged 408(iron block lq4 to start with) for a customer of mine in plans of procharging it. i havent ordered all the internals yet but thats why im here now with 2 questions
1. what compression would be best to go with, i was thinking 8.7:1, basically what were shooting for is the nastiest engine we can get to run on 93 octane. meth injection is an idea too.
2. Which model procharger should we go with, im thinking F1A, like i said it will be street driven, not really daily, but it needs to deal with some stop and go. theres no emmisions here so thats not a big deal
BTW its going in a 99 TA 6speed
thanks, Mark

What are the goals for the car? On a 4-bolt setup you can run it close to 1000 rwhp without pushing a lot of water, after that the issue becomes pushing water/lifting the heads. As stated above if your going procharger an F1 model should be more than enough for your build, but again it depends on the customers goals. As for compression I would agree and reach out to Bob @ EPP. Lots of FI builds nowadays are running 9.0-9.5:1 compression so you could probably go a little higer than 8.7:1 but id ask the pro's about that.

the guy basically just wants all he can get, i was hoping for more than 750 through the t56 and 9 inch.
i was planning on talking to epp, thats where i had planned on ordering the F1 through

The crew at Exotic Performance Plus are building me the exact motor.I will still use my ProCharger from my present LS1 and up the boost for the new motor.I am looking foward to a possible 650 RWHP on the new set-up.They build a lot of motors and they also sell and install Pro Chargers.Give them a call.

Thanks everyone, we appreciate it! We do indeed shoot for a compression ratio around 9.5/1 for using an ATI ProCharger. There is no need to drop the compression ratio any lower than this. I agree that the F-1A is the blower to go with. Bob
