Estimated power with a Procharger on H/C/I car? Just getting ideas here... I don't want too much power I like the street ability of my car.
My car makes 450+ to the wheels now with MS3, #42 injectors/255 pump, 90/90 intake and ETP 215 heads and all other "supporting mods".
If i were to put a P1 or D1 on the car and push 8 pounds do you think it would be worth it and how much power do you think will be gained?
M6 car btw. Nitrous is out of the question although it has crossed my mind.

You with bleed of some boost with that ms3 cam for sure. Its not (ideal) for boost but it will still work. I would think you would be in or over the 650hp range with a D1.

630 is a low guess but at least you won't b disappointed hoping for more and ending up with less.... i wouldn't run more than that on a stock short block though.....

I have some questions what is your CR with the heads you have? I hope you plan on spraying some Meth as well.
600rwhp is gonna be hard to hit with no Meth. Also don't even think about buying a P1 just get a D1 Then buy some 60 or 80 lb injectors and a Good Meth kit like Alky control. Then 600-650 should be easy but might take a little more than 8 psi
I had a friend make 670rwhp in a Vett last year with 11 psi stock bottum end ls1 with heavily ported 241 heads and a NA cam that was on 93 and Meth

i would cringe every time i got on it makin that power on a stock short block....i do now with my baby 571rwhp........lol
i agree D1 only. leave the P1 for the 2v mustang guys lol.... if your near 11:1CR....id be rethinking that 8psi....or like he said.....lots of meth. E85 would work also.

I was in the exact same position as you last year. PI heads (MAST), 227/235 610/615 113 cam, long tubes, FAST 90/90 and ended up putting on a D1SC with front mount intercooler, 60lb injectors, dual intank pumps but no meth.
I only wanted to make 8-10psi but ended up making 15psi at 6800 and quickly realized I was out of injector at that rpm, but then again I was seeing 10.8-11:1 afr, so I needed to lean it out a little.
Needless to say after popping #7 ringland, I'm in the process of building a forged shortblock. The car was a beast, at least to me.
Meoh/water injection is definitely needed if you plan to keep the shortblock together because the factory rings are not boost friendly at this level. Some guys have popped #7 just running high compression NA.
I have no idea how much dyno power it was making, but it was definitely fun.

I made 2 mistakes, 1, not backing down the pulley size once I realized how much boost I was making, and 2, not putting water/meoh on it right away.
My tune was good, and detonation wasn't a factor, but the amount of heat on the pistons was just too much for the factory shortblock.
Trust me, I blame no-one for what happened and don't feel bad about it. Fact is, the power was addicitive and I didn't want to back down the boost, so I knew when I got my bonus this year it was going towards a forged shortblock. Unfortunately, I popped the motor about a month before I got my bonus, oh well, it was fun.

See this is the thing.. I only want to push 8 psi... Nothing more to be on the safe side with a SAFE tune...
Big king DICK in the town i live in has a ZR1 and thinks hes the **** and unfortunately my car doesn't make quite enough to take him. My goal is 620-650 range and that's why im asking.
The block has just been rebuilt with all new pistons due to #7 ring going out ( ran lean shitty tune ). I was just curious if it was really worth putting a procharger on it with the current setup I run. Sounds do-able.

If I could go back right this instant, before blowing my ls1 on the dyno...
procharged (9lbs) @ 600rwhp on the dot with a 4.13 pulley at 5800 rpm.
I would do this to make it last:
Tone it down to 7-8lbs
Add meth or E85
Add colder plugs (ngk tr6)
I WOULD ABSOLUTELY NO DOUBT ADD HEAD STUDS AND GASKETS
ADD ROD BOLTS
And keep the timing and the AFR real safe.
Only spin it to 6k instead of 6550
ALSO I would make sure the steam vents were (all 4 for 01-02 ls1's) vented to keep temps down, and put the highest flowing injector on number 7.And although the ms3 will "work" its not at all ideal. Id ditch it for a 228r or anything else basically.
Just my $0.02

you dont need studs for 8 psi man. mine is 11.5 afr, redline at 6500rpm... its all in the tune. people want to much with no risk. only thing im concerned with his setup is compression ratio. thats really gonna limit the amount of boost he can run because of detonation. thats y i suggested E85 or Meth. but head studs arent a must at 8psi imo. or rod bolts, unless its a 98, in that case, then id only spin it to 6000rpm..

I have ARP studs on everything with cometic gaskets I think I should be fine there.
As far as racing and getting on it... I hardly race it or anything... Ill get on the car hard maybe once a month.
Went back with stock pistons... DUMB on my part but didnt have the money for the pistons/rods/crank at the time.

im just bustin your ***** man lol. i would of done the same thing. I busted the rear end in mine 2 weeks ago because i couldnt help but get on it, and i knew the 10 bolt wouldnt last haha... I thought unburnt fuel maybe collected in the ring land and detonated causing it to break. though u had like a 10.2:1 afr for some reason?? hmmm i dunno. hows the short block coming along?
Real early on when I first put the procharger on, I had added a bunch of fuel up front to make sure I ran rich rather than lean. The entire time I never touched my commanded afr as it was set for 11.2:1 at max torque and tailed off to 11.5:1 at redline.
When the motor popped in January, I was 10.8:1 at peak torque and 11.2:1 at redline, so the tune was getting closer, but wasn't spot on yet. Definitely wasn't risky or dangerous as other's have insinuated.
