Soon, I will put to the test the 7.5 with a detriot tru-trac and 28spline mosers
with my car i'd assume and hope it can do low 11s high 10s

before i touch the fuel and bigger turbo

I'am unsure both should be equal...
When i get more money later the tranny has to come out anyway to change the syncros. depending how i feel the clutch i'll change it then

and honestly you have to tell me which banks your robbing or how your playing your stocks.. very nice tho again.. its gonna be a bit for me to get my forged block

lol iam going paycheck to paycheck.
new promotion at work helps to plus online orders and local porting and polishing as well as side jobs

Block and head is back from the machine shop
pictures tomorrow
build starts next week

head flow

intake-235cfm

sticking with the camshaft that i have for now

i cant wait to see some numbers and pictures!

What's the stock piston's compression ratio? Is it lower or higher than 8.5:1?

Higher

radomirthegreat · February 14th, 2009, 02:28 AM

Since the 3.8 is naturally aspirated, does it then have a 9.5:1 or 10.0:1 compression ratio? Chris, which turbocharger are you using? Something in the 60mm range?

9.3:1 ratio.

That's what i have but the problem you run into which J greatly informed me is it limits you to how high you can go on pump gas. stock ratio will let you go to about 540rwhp on pump gas before you have to go to race fuel. the 8.5:1 ratio really opens doors and allows somewhere in the 700+rwhp range. i forgot exactly.

however 500rwhp is my goal with this p1-sc procharger. this build though however has a huge goal in mind and will need 8.5:1 compression. This will just make it easier and not much power is lost on our engines with the compression difference.

radomirthegreat · February 14th, 2009, 06:16 PM

What's the stock bore on the 3.8? You can go down to 8.5:1, but then you can over-bore a bit to get some more compression. You may make it up to 8.6:1 if you can bore enough.

You know that wont ever happen.

radomirthegreat · February 14th, 2009, 06:28 PM

If you get a smaller charger, you can keep stock compression. It would help keep the charger in its range of efficiency. Either way is possible. Why wouldn't you be able to get to 500 WHP? That or more is what I'll get with my turbo Bonneville that I'm building up. Seems possible as long as you keep pouring money endlessly into it.

SleeperStang88 · February 14th, 2009, 06:30 PM

ssstang, im very confident that stangcharger could hit over 500 rwhp with his s/c that he has......it will be tough but im sure itll happen, and even if he cant make it that high with that particular s/c then he can go from a p1-sc to a D1-sc which is much higher rated for hp

itschristorres8 · February 16th, 2009, 01:14 AM

with a p1 s/c it will be very hard. the SSX intake will greatly help him though.
either way s/c's on these cars are brutal, the more power you demand the more power THEY demand which means it wont be as efficient.

9:31:1 or 9:39:1 is the stock compression ratio.
The stock 3.8 rods are garbage and frail but no one intended it to handle gobs of power. although it worked for 439rwhp with me.

CURRENTLY I'am using a SC44 turbo which is a little bigger then a Pt57 and similar to a 60-1
it has a .68a/r
in the future that will change

stock BORE is 3.810 (belive thats piston Diameter.)
Pistons I personally went with are .030 over= 3.840 pistons
Total seal rings
the block you CAN go .060 over though which someone has done

but compression rating has nothing really to do with bore...
compression ratio is more piston height, dish, and cylinder head
if you mill your heads down .02 then you've increased your compression
My pistons as you can see have a decent size dish i think its 16 or 18cc

bore will not effect compression ratio

radomirthegreat · February 16th, 2009, 01:24 AM

Awesome info. What happened to your 439 WHP bottom end?

If you go from 3.81 to 3.84 or 3.87 pistons, you will have .03 or .06 inches of more piston diameter. Your compression ratio with an 8.5:1 piston may then go up to 8.51:1, maybe. It does increase the compression just a tiny bit more. Definitely, getting the heads milled down does help a whole lot more. I just thought I might mention the slightly increased comp, but I do understand it's barely noticeable.

Have either one of you been around here long enough to know shit? I guess not.. Phil and Keith(novi2k) can't hit 500hp do you think a p1 is going to hit 500? Even Gary was having trouble touching 500rwhp with the F1 procharger. And Phil has sucked every inch of hp out of his motor, and his C&W upper intake. - Now back to chris and his build which should make 500 easy -

radomirthegreat · February 16th, 2009, 02:00 AM

I guess I haven't been around here long enough to know that you get diminishing returns on money poured into your car.

I was writing to Chris when I said he could retain stock compression and go with a smaller charger.

ESG-642T · February 16th, 2009, 02:14 AM

Yep spend money on a smaller turbo when your chasing higher hp goals in a street car on pump gas!

We don't have a facepalm smiley do we?

radomirthegreat · February 16th, 2009, 02:42 AM

I asked what size he's using now. The Precision SC44 is easily capable of taking smaller engines beyond 500 HP, but in this case it's too small for that much horsepower. If he were to have had a large turbo now, I would have lucked out in advising him to go with a smaller one or keeping that one and stock compression.

You should be glad there's no facepalm smiley here. With the kinds of posts you have been making here, you would be by now sick of seeing it all the time.

Yeah no, you realize chris isn't responding to you because and I quote "itschristorres8 (12:12:33 AM): lol im just not going to respond to him
itschristorres8 (12:12:46 AM): i have no time for stupidity or ignorance"

Later.

radomirthegreat · February 16th, 2009, 03:18 AM

Sometimes different ideas are seen as stupid and/or ignorant. I'm not the one building a 500 WHP Mustang, so my consequence if I'm ever stupid or ignorant in this thread is minimal if anything. Chris is building a heavy duty Mustang, and if he doesn't consider all possible options, he faces a ton of consequences involving money, time, knowledge, etc. I'm sure he will reach his goal, but there's no reason to consider opposing viewpoints as stupid & ignorant.

I don't think anything bad about what he's doing, and he's actually doing it. I'm just talking about different options, and already people think I'm wrong. It's his thread. Of course he gets to decide if he's going to respond or not. Eventually though, if he keeps thinking other ideas are so dumb, those with other different ideas will return the favor.

Zatrekaz · February 16th, 2009, 10:04 AM

Chris knows what he is doing, and I am sure he has considered all options.
