Compression ratios

Nope, rods and pistons.

BTW, I'm running 11 lbs boost, 450 rwhp on the stock block, so far, so good.

Good to know. i was going to go with DR's vortech or paxton kit. I'm leaning towards paxton right now. Anybody running a centri style setup around here want to help me out. I want to make good power but not risk integrity of my stock motor

PM Marauderman, he's running a Vortech, IIRC around 13 lbs boost.

On my previous car I ran 456rwhp and 412rwtq at 12# on a vortech s-trim.
The car had been FI since 27k miles and I sold it with 72k.
On race gas I ran 502rwhp and 456rwtq. I did about 20 passes on the car at that power level, several high 11 sec passes with an 11.67 at 65* weather.
Before I sold the car I did a compression test and the lowest one was at 182.
The durability depends on the maintenance and tune.

The pros and cons between air to air and water to air? Sounds like it holds up way better than I expected under boost. What pulley size is 12#s on that setup?
 
I would get a forged shortblock from a well known builder before I'd ever drop the coin for an aluminator. Btw, my original block with 130+k on it still has the original crosshatch on the cylinder walls!

The aluminator would be the easy way out just since everythings assembled. I like doing things myself anyways. "Built Not Bought" is my motto

Air to air is a way simpler setup, and you don't have to worry about a pump going bad
The bad is if you do long extensive burnouts the intake temp will rise incredibly quick.
I ran a 3.33 pulley and spun the engine to 6500rpms.

What do you set your 1-2 and 2-3 shifts at? My burnouts aren't that long and extensive. I know when I get my point across ;). Sounds like I'd want an air to air setup with the 3.33 pulley just to be safe. Now basically the only downside of the air setup is obviously always have to have airflow otherwise i'll burn right up.

If you're going centri, keep the CR high. They don't spike the dynamic compression at low RPM boost like a PD blower does, so you can get away with more compression. Use flat top pistons and call it a day.


i bet you will have an aluminator and will be wondering why the hell the stock one wont blow up lol

That's what happened with me, the transmission gave up before the engine did.

I already built my transmission ;)
 
I decided eaton swap it is, where do I start??I know I need the eaton M112 blower, lower intake manifold, intake plenum, kenne bell boost-a-pump, ford gt supercar fuel pump, 39# injectors, handheld tuner, coolant reservoir relocation, move my battery, custom brackets (anybody in the know on who here can make 'em? If not I can fabricate my own, modify my coolant crossover tube 1 inch lower to clear snout and pulley, intercooler (which one? if not custom piping with a IC from frozenboost.com) IC pump and custom bracket to mount it. Anything else guys?

PM gortch for the brackets

I highly recommend the Frozenboost Type 100 IC heat exchanger, you won't be disappointed with it.

PM me with your e-mail address and I can send you some info on parts needed, approx pricing, etc.

I saw the crosshatch on a crown vic cab motor that we were taking the pi heads off... thing had over 300k on it and still had the crosshatch hone marks. Mod motors will run forever if you leave them alone. But that's not fun. :D
