Any 427 LS3 guys running a TVS or Whipple setup?

The only time I've had the car N/A was when I got it new. When the car got 10K miles on it I had the TVS2300, cam, headers, CAI all installed at once. Once that motor needed to be freshened up I went with the forged stroker with fairly good components in it for some security and perceived durability. The stock motor was at around 530 WHP and I'm about 100 up on that now with a considerable increase in torque across the board. I can tell you the manacharger will get you to 10 psi with this combo for sure. For me , that's all I have planned for a while .

So, I'll probably be going with a D series ProCharger. 7-8 psi. Looking at keeping the same cam and upgrading fuel. Going to make some calls this week and see what I kind find.

lol when will people learn that chasing hp numbers is always better/more satisfying boosting.

Good decision, you will easily get 7-8psi and should be about 700 rwhp since your CR is pretty stout.

I was able to get 11-12 psi out of my D1SC running a 3.7" pulley and 700/700rwhp/tq. I have major belt slip at 5300rpm and thats where my HP numbers peaked and flat lined all the way to 7000rpm so I am leaving about a hundred or so hp on the table. My motor was built at 9.4:1 CR, i have always planned to crank the boost way up. Next up is a TT system and 18-20 psi

Ya know. This thing is going to be purposed as a street car, no intentions on ever turning it into a track monster. Any chance I will regret procharging it?

I'm with that very question.

If it was me, I wouldn't have a second thought using a procharger or a Vortec, they make the most sense to me with what you are wanting and what you already have done.

I would look at Bull's build and the issues he has mentioned in his last few posts though with his D series blower. I personally would go bigger than the D1SC, just in case you ever decide to crank it up, you're not having to buy parts again. I've replaced replacement parts already and it bites you in the ass even harder the second time. Figure out where you want to be, and buy at least 1 step bigger so you will still have room to grow.

I haven't seen anyone build a car to meet their goals of 600rwhp, that hasn't come back and bumped it to 650, then 700, etc... When I started my plans, I wanted 550rwhp and passed that by nearly 100 and I'm still looking at adding a little more. A 750hp car can be incredibly street friendly when its done right, and that will make you want more. I think it's sickness.

All good points. I suppose it just a matter of throttle control. As long as you dont mash the gas everywhere you go, it can be very manageable. Pretty much how you would drive an exotic/super car. Know a few guys with them and it took a lot of getting used too. One figured it out after a 26K reapair to the front end of his Mercialago.

Excellent advice. I would start with an F1C and pulley it accordingly. This will leave you the option to go all the way to 900rwhp if you ever get bored. The F1C should not be too much more than a complete D1SC setup.


I was going to go the F1c route when we maxed out the D1 on my new motor but my shop said they would like to do Twin Turbo using PTE6766 turbos. This will be a custom install/build and it will be less than upgrading to an F1 head unit. (they are really hooking me up with this!)

In all honesty, i am having a bunch of fun with the D1 at the moment. The torque of this motor down low and the power up top is pretty un manageable, and im only at 700/700 rwhp/rwtq. This is with the HP peaking at only 5300 due to major belt slip. The D1 is maxxed out

Im not too sure how accurate this dynocom dyno was however. Later in the week my car toasted the bearings on the dyno while working some tune issues. So i dont know if the dyno was completely accurate during the tune. I know my butt dyno indicates this car has a lot more than it did on the LS3 when i was at 715/611 rwhp/tq.

TT will put me over 1000 to the wheels

Exceptional advice!!!! Also look on the forum Marketplace. There was an F1R cog at a killer price at one point. You can often save $s going with slightly used items from this forum and get more than you planned to originally.

If I can find a used intercooler/F1 kit I would be game. Would have to chase down some fuel system components, but I would rather buy those new.

Yea, i was gonna mention if you go F1 or even crank up the D1 you should go with an ADM dual pump setup or bigger return style with ID1000 or equivilent injectors. The Squash performance has been awesome so far!

Keep whatever you come up with fed well and it should last a while
