ok want to get off the juice and into some boost. the problem is im running 243 heads milled to 59 cc with a .045 gasket. the cam is not ideal (232/236 580 580 112+4) but i think it will do until i get a built long block. i was thinking of getting an A&A kit with a YSI and just run a big pulley, alot of meth, and a conservative tune. one thing i do have in my favor is DA, it goes from 4000' in the winter to 8000' in the summer. do you think it would be ok to shoot for around 600-650 rwhp without it being a ticking time bomb?

Whats your compression ratio ?

my calc. shows around 11.4 with .080 flycuts.

Good question. I also have high CR- 11.3. I have been told by 3 tuners now that even with forged internals IF you go with a turbo or centri setup don't go much over 5-6 lbs of boost. More than that your engines longevity is in serious question.

Of course a buddy of mine is running 14 lbs through a twin .50 APS kit on his 11.1 06 GTO and has been doing so for about 10k miles with no serious issues.

Its certainly been done... Meth is your friend...

I'd def. run meth on a higher CR motor.

That' should not be hard to achieve.

You can run some thicker gaskets to help drop the compression.

pretty sure speed inc did a f-body with a 408 with 11:1 with an aps kit. with 7 lbs of boost they made like 700 plus horse. with the compression that high you dont need alot of boost to get high power numbers.

i am running a 10:1 motor. but i aslo am going e85.

Like these?

I also heard you can run heads with a larger chamber but economically speaking it would be cheaper to just tear the engine down and run lower CR pistons.

Sig check! Id like it to be a 9:1 motor, but eh, eventually!

It will be a 95% C16 motor.... pump will be E85, or 2-5#s on 93 and a neutered timing table...

i tried calling and talking to you about this and a aps kit but the guy that answered the phone said you were to busy to talk. when i told him joking "ok....ill call a competitor" he hung up on me. kinda sucks too since your pops was so nice to me a few years ago when i was out there having godspeed tune my old ta back when the x2 hit the market. hell i even run the pros on my current Z06. anyway, i ended up buying some 317s to drop the compression.

I am about to do a TTIX build with a lS3 418 with 10.8cr. I have been low cr and didn't like it. Thought I would try this.
